So do the examples given meet the criteria of macroevolution as defined?
Hi again idscience,
... The def of macro is changes above the level of species. According to many evolution experts, speciation is macro-evolution, ...
Yes, because you were incapable of providing the definition the administrator for the forum had to step in and do your work for you.
I take it from this response that you do accept this definition without reservations or quibbles.
... , so that is no help. Does not get me to my questions.
au contraire.
Message 1: I am interested in todays best evidence for macro-evolution.
I am interested in hard evidence that moves macro-evolution from hypothesis to theory? Evidence of the same standard that is demanded from intelligent design science. ...
Now that we have a definition of macroevolution to use and to compare evidence against there have been several posts that provide you with examples that show that macroevolution occurs, that it is a fact that it occurs.
See Message 81, Message 84, and Message 85, just for starters. With just these posts your questions are answered for this thread topic, even though there is a lot more evidence avaiable.
Macroevolution in biology and evolution is not an hypothesis or a theory, it is a process that is defined for the purpose of discussing different levels of evolution that we see in the fossil record, in the historical record, in the genetic record and in the world around us.
The theory involved with evolution is the theory of evolution.
Now if your questions still aren't answered, it's could be because you did not frame them correctly, mixing up macroevolution with the theory of evolution and having false expectations, based on a (demonstrated) incomplete knowledge of biology in general and evolution in particular.
photoreceptor pathway?
flagellum motor?
how are they built by a blind undirected process?
This is not macroevolution, nor is explaining this to you in any way connected to providing you with evidence for macroevolution. If you want to discuss these you need to start another thread.
There is a lot more evidence for macroevolution that we can discuss, however you need to focus on your issue of evidence for macroevolution, review the evidence already provided and confirm or deny that they meet the criteria for macroevolution as defined.
If you feel they meet the criteria for macroevolution as defined, then your questions for this thread are answered and it can be closed.
If you feel that they do not meet the criteria for macroevolution as defined, then you need to show why they don't and substantiate your assertions with evidence.
If you don't understand how they meet the criteria for macroevolution as defined, then feel free to ask questions
Enjoy.

Re: Is it a duck or is it another pratt?
Hi again idscience,
How about the mouse is still a mouse. No morphological changes, no intermediary structures or systems. What about all the different species that can breed together? human and Neanderthal for one example. I would consider this micro. A variation, not a transformation.
Curiously, what you consider it is irrelevant. This thread is about evidence for macroevolution according to the scientific definitions provided
Message 81 (abbreviated) :
... for the purposes of this thread macroevolution is defined as evolution above the species level. A gray squirrel evolving into a red squirrel is macroevolution. ...
And idscience could easily have looked this up on wikipedia:
Macroevolution - Wikipedia
quote:
Macroevolution is evolution on a scale of separated gene pools.[1] Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution,[2] which refers to smaller evolutionary changes (typically described as changes in allele frequencies) within a species or population.[3]
The process of speciation may fall within the purview of either, depending on the forces thought to drive it. Paleontology, evolutionary developmental biology, comparative genomics and genomic phylostratigraphy contribute most of the evidence for the patterns and processes that can be classified as macroevolution.
quote:
Berkeley:
Biological evolution, simply put, is descent with modification. This definition encompasses ... and large-scale evolution (the descent of different species from a common ancestor over many generations). Evolution helps us to understand the history of life.
Macroevolution - large scale evolution - is the descent of different species from a common ancestor over many generations.
quote:
UMich:
The gradual change of living things from one form into another over the course of time, the origin of species and lineages by descent of living forms from ancestral forms, and the generation of diversity
Note that the ... definition emphasizes the appearance of new, physically distinct life forms that can be grouped with similar appearing life forms in a taxonomic hierarchy. It commonly is referred to as macroevolution.
Macroevolution - The gradual change of living things from one form into another over the course of time, the origin of species and lineages by descent of living forms from ancestral forms, and the generation of diversity.
These help define what "above the level of species" means: the generation of new species and the formation of nested hierarchies of descent from common ancestor populations and the generation of diversity.
Now that you have a definition to use, and people have provided you with evidence of evolution that meets the criteria as defined, do you agree that your thread question is answered?
Enjoy.

Re: idscience and the definition of macroevolution
Hi again idscience,
Wow, yurrr shuuur hung up on the definition thing M8.
No, I am "hung up" on discussing science with the correct scientific terms and a proper understanding of them so that communication is achieved.
Now, how about giving it a shot at answering my questions on complexity being built by Darwinian means, yes, even your definition of macro-evolution.
Amusingly such explanation has nothing to do with whether or not there is evidence for macroevolution, nor is it a part of macroevolution as defined.
You appear to be confusing the theory of evolution with the process of macroevolution.
If you want to discuss how the theory of evolution explains this, then start another thread and finish this one by acknowledging that evidence of macroevolution has been provided that meets the definition provided.
If I am understanding you correctly, with the current definition of macro-evolution on the table, as long as evolutionists can cite examples of speciation, no other evidence is required to prove common descent? Can I quote you on my site?
First, no theory in science is proven. Theories can be invalidated by contrary evidence or validated by confirming evidence, but validation means that the theory can only be considered tentatively true at best.
Second common descent is just the process of offspring from parent, and it can be demonstrated by evidence to have in fact occurred. The theory of common descent would be that this process can be applied to larger groups to form a tree of life. So far the evidence for this is that it can indeed be applied to virtually all known life -- ie that it can be considered a valid theory.
Third, what you can quote on your site is this:
(1) The process of Microevolution involves the change in the frequency distribution and composition of hereditary traits within breeding populations from generation to generation, in response to ecological challenges and opportunities.
Mutation can cause change in the composition of hereditary traits carried by individuals of a breeding population, but not all mutations do so. In addition there are many different kinds of mutations and they have different effects (from small to large).
Natural Selection and Neutral Drift can cause change in the distribution of hereditary traits within the breeding population, but they are not the only mechanism that does so.
The ecological challenges and opportunities change when the environment changes, the breeding population evolves, other organisms within the ecology evolve, migrations change the mixture of organisms within the ecology, or a breeding population migrates into a new ecology. These changes can result in different survival and reproductive challenges and opportunities, affecting selection pressure, perhaps causing speciation, perhaps causing extinction.
Mutations of hereditary traits have been observed to occur, and thus this aspect of microevolution is an observed, known objective fact, rather than an untested hypothesis.
Natural selection and neutral drift have been observed to occur, along with the observed alteration in the distribution of hereditary traits within breeding populations, and thus this aspect of microevolution is an observed, known objective fact, and not an untested hypothesis.
(2) The process of Macroevolution involves the development of new species, the formation of nested hierarchies of descent of new species from common ancestor populations, and an increase in the diversity of life.
This looks at the continued effects of microevolution over many generations, where the accumulation of changes from generation to generation become sufficient for new species to develop that are different from the ancestral parent populations. This lineal change in species is sometimes called phyletic or arbitrary speciation.
(a) The process of Phyletic Speciation involves a lineage of descent from an ancestor population accumulating sufficient differences through microevolution that, when compared to the ancestor population, it would appear to be a different species.
This is sometimes called arbitrary speciation because it is difficult to agree on where the line of division from one species to the next occurs, how many times this occurs in a given lineage, and because the definition of species itself is fairly arbitrary.
The amount of change in phyletic speciation can be compared to the changes seen in divergent speciation between parent (ancestral) populations and the daughter (descendant) populations as a check on the amount of change to be considered.
(b) The process of Divergent Speciation involves the division of a parent population into two or more reproductively isolated daughter populations, which then are free to (micro) evolve independently of each other.
The reduction or loss of interbreeding (gene flow, sharing of mutations) between the daughter populations results in different, independent, evolutionary responses in the daughter populations to their respective and different ecological challenges and opportunities (including the existence and impact of the other daughter population/s on survival).
Independent evolution within each subpopulation results in divergence of the subpopulations from each other. Divergent speciation forms a branching pattern of descent from a common ancestor pool, and results in added diversity of species. Further instances of divergent speciation adds further to the branching pattern and results in a nested hierarchy pattern.

Phyletic speciation with the development of new species by extended microevolution in a lineage of descent has been observed to occur, and thus this aspect of macroevolution is an observed, known objective fact, and not an untested hypothesis.

The formation of nested hierarchies of descent from common ancestor populations has been observed to occur, and thus this aspect of macroevolution is an observed, known objective fact, and not an untested hypothesis.
The addition to diversity by increasing the number of species and higher groupings has been observed to occur, and thus this aspect of macroevolution is an observed, known objective fact, and not an untested hypothesis.
One single example that shows all of these processes in the fossil record is:
Conditions for quoting are (1) that it be quoted in full, (2) that it be properly cited as a reference and (3) that you give me irrevocable permission to edit your site and correct any errors you make (it could use some help anyway).
or you can just link to this thread and this message so that people perusing your thread can be exposed to what the science actually says.
I don't care so much about what you call it, I am interested in how it occurs? Something a little more substantial than, changes of millions of years, and a little deeper than, one fish can't seem to breed with another one.
Again, this doesn't apply to the definition for the process of macroevolution or to the provision of evidence that macroevolution occurs, which are the topic of your thread.
What you are asking is how the theory of evolution explains the diversity of life, and this is a different question from your initial post.
I could suggest you take a course in evolutionary biology at your local community college or higher, or I could suggest that you read through all the pages on
http://evolution.berkeley.edu/...shtmlBerkeley Evolution 101
Then start a new thread on what you don't understand.
Enjoy.

macroevolution is a process not an hypothesis - are you talking about ToE?
Hi idscience,
Because speciation as stated before, is considered (by scientists) to be macro-evolution, it does not get me to the evidence I am looking for.
Then perhaps you are not looking for evidence of macroevolution by the definitions provided but something else. If response to your question does not give you the answer you expect then it is time to review your question/s to see if what you asked was what you needed to ask.
Perhaps if you can define better what you expect to see, and why, then we can see if what you expect is based on false understanding (something that does not actually occur under evolution, such as the hopeful monster pratt), or whether it is an aspect of evolution that is explained via the theory of evolution (which you apparently confuse with macroevolution).
If you are asking how organism develop specific aspects seen in the fossil record then you are talking about the theory of evolution rather than macroevolution.
Does anyone have a pathway to develop a photoreceptor, or a flagellum motor?
Yes, but not under macroevolution. This would be under how the theory of evolution explains what we see in the world around us, in the historical record, in the fossil record, and in the genetic record.
macro is a hypothesis because it is based on assumption that similarity = common ancestry. It stands on assertion, not facts.
Sadly, for you, this opinion has already been shown to be false. It is a process and a the occurrence of macroevolution is an observed and documented fact.
Macroevolution is a process that is defined in order to facilitate discussion about evolution, not an hypothesis. Look at the wiki article:
quote:
Macroevolution - Wikipedia
The process of speciation may fall within the purview of either, depending on the forces thought to drive it. Paleontology, evolutionary developmental biology, comparative genomics and genomic phylostratigraphy contribute most of the evidence for the patterns and processes that can be classified as macroevolution. An example of macroevolution is the appearance of feathers during the evolution of birds from theropod dinosaurs.
bold added -- it's a process not an hypothesis. The definition allows different aspects of evolution to be classified as macroevolution or not.
Again, it looks like what you need to ask about is the theory of evolution:
The Theory of Evolution (ToE), stated in simple terms, is that the process of (micro) evolution, and the process of (divergent) speciation, are sufficient to explain the diversity of life as we know it, from the fossil record, from the genetic record, from the historic record, and from everyday record of the life we observe in the world all around us.
So when you are looking for an explanation of how x could have evolved you are asking about the theory of evolution. Whether x is classified as microevolution or macroevolution is irrelevant.
Enjoy.

definitions, macroevolution etc
Hi idscience,
You spend a lot of time asking me for defintions and explanations while providing non.
Message 29: For instance, I'll define microevolution (seeing as you agree completely with this process):
Microevolution is the change in the frequency distribution and composition of hereditary traits within breeding populations from generation to generation, in response to ecological challenges and opportunities.
Also see Message 81, repeated in Message 107, and then see Message 112 for several additional definitions.
Both the bird wing and the bat wing have the same bones in the same order as limbs. What's new about that?
That is common design.
Sadly, for you, this is not common design but analogous traits:
Homologies and analogies - Understanding Evolution
quote:
Not all characters are homologies. For example, birds and bats both have wings, while mice and crocodiles do not. Does that mean that birds and bats are more closely related to one another than to mice and crocodiles? No. When we examine bird wings and bat wings closely, we see that there are some major differences.
Bat wings consist of flaps of skin stretched between the bones of the fingers and arm. Bird wings consist of feathers extending all along the arm. These structural dissimilarities suggest that bird wings and bat wings were not inherited from a common ancestor with wings. This idea is illustrated by the phylogeny below, which is based on a large number of other characters.
Note that there is nothing similar in the use of the finger bones, their length or position. In the bird wing several of the finger bones are bunched together, shortened or fused to make the end of the wing stronger, while all the fingers are spread out and extended in length in the bat wing.
That is not the same design, it is not common design.
My point ... is, a birds wing and a lizards leg, are not similar ...
And yet they still have similar bones in the same order from pelvis to toe, the differences are derived traits that have evolved since the time of their shared common ancestor that gave them the pattern of bones.
and if macro does not have to produce novel structures....????
Curiously, macroevolution, microevolution or evolution in general do not have to produce anything. Macroevolution is a process that involves speciation, the formation of new species, the development of nested hierarchies and an increase in diversity.
Evolution is a response mechanism.
... produce novel structures....????
What's a novel structure? Is a webbed foot a novel structure? We see instances of mutations all the time where toes are webbed in offspring while their parents do not have webbed toes. Is that what a novel structure is?
You spend a lot of time asking me for defintions ...
That's because I need to understand what you mean. For example, you could not define macroevolution and you still can't explain what you think it means except that the definition used in science does not give you the answers you want.
I'll take that as a no, you do not have a usable definition for "information" that would allow one to measure it and see whether or not it increased.
This is of no concern to me nor to biology in general or evolution in particular, as this term is not used in this science. We get along fine without it.
Enjoy.

Re: so can you define macroevolution or not?
Hi Big_Al35
Here is a source from your source which I don't agree with
A review of Michael Denton's book?
quote:
Conclusion (updated: 29 July 2005)
Michael Denton often is called a creationist. The title of the first Chapter of his book is: "Genesis Rejected", but the chapter contains a historical account, not a defence of Genesis. It is true that Denton accepts Paley's argument from design. This is a philosophical argument for the existence of a supernatural designer. But it is also a 'natural theology' in the tradition of Paley. Since Denton rejects (macro)evolution and his own Typological Model does not explain the origin of species, he needs an answer. Paley has given him the answer. This is a nonscientific answer because both philosphy and natural theology are outside the natural sciences. With hindsight, Michael Denton could be called the first 'Intelligent Design Theorist' (5). Denton must be aware that Paley's answer is outside sience, because:
"Undoubtedly, one of the major factors which contribute to the immense appeal of the Darwinian framework is that, with all its deficiencies, the Darwinian model is still the only model of evolution ever proposed which invokes well-understood physical and natural processes as the causal agencies of evolutionary change."
So he says that Denton is a neo-Paleyist that rejects macroevolution and that evolution is based on natural processes. Big Whap. So why do you disagree with it?
It cites that the Darwinian model is still the only model of evolution ever proposed which invokes well-understood physical and natural processes as the causal agencies of evolutionary change.
And?
Curiously, that is what science in general does, including physics, chemistry, astronomy and geology for starters. If you have trouble with science taking an agnostic position, then you should talk to one of the people on the clergy project list.
The difference between Darwin and Mendel was the basis of heridity; Mendel had it right but Darwin had it wrong
Not really: Mendel had no clue about natural selection or mutations. What he did was isolate dominant and recessive hereditary traits, not the genes responsible for them. He had instances where this experiments did not work out quite right and he ignored these anomalies ... caused by mutations. His work was important because nobody had done this isolation of dominant\recessive heredity before and his ignorance of genes and mutations was universal at the time. He started science on the path to finding genes.
Darwin noted that natural selection operating on the observed variation in species was sufficient to explain the origin of species.
Interestingly, the modern theory of evolution incorporates Darwin's natural selection with Mendel's hereditary traits and several other processes.
As I've said previously on this thread (getting back to the topic):
(1) The process of Microevolution involves the change in the frequency distribution and composition of hereditary traits within breeding populations from generation to generation, in response to ecological challenges and opportunities.
Mutation can cause change in the composition of hereditary traits carried by individuals of a breeding population, but not all mutations do so. In addition there are many different kinds of mutations and they have different effects (from small to large).
Natural Selection and Neutral Drift can cause change in the distribution of hereditary traits within the breeding population, but they are not the only mechanism that does so.
The ecological challenges and opportunities change when the environment changes, the breeding population evolves, other organisms within the ecology evolve, migrations change the mixture of organisms within the ecology, or a breeding population migrates into a new ecology. These changes can result in different survival and reproductive challenges and opportunities, affecting selection pressure, perhaps causing speciation, perhaps causing extinction.
Mutations of hereditary traits have been observed to occur, and thus this aspect of microevolution is an observed, known objective fact, rather than an untested hypothesis.

Note that Phyletic Speciation is included under (extended) Microevolution, and that this combined with Divergent Speciation means that the process of Macroevolution is included in the theory.
Alternatively, we can drop the distinctions on evolution and speciation and simply say:
(4) The Theory of Evolution (ToE), stated in simple terms, is that the process of Evolution, and the process of Speciation, are sufficient to explain the diversity of life as we know it, from the fossil record, from the genetic record, from the historic record, and from everyday record of the life we observe in the world all around us.
This theory is tested by experiments and field observations carried out as part of the science of evolution.
Macroevolution is a process that is defined as a distinction from microevolution, to apply to different aspects of what is seen in the objective evidence we have, specifically when we look outside what occurs within a breeding population at what causes diversity.
Like any theory, the job of the ToE is to explain the evidence in manner which invokes well-understood physical and natural processes as the causal agencies. It does this.
Thus if you look at the fossil record and see X and you want to understand how X came to be, your don't ask microevolution or macroevolution to explain it, you ask the ToE to explain it, using the known processes involved in microevolution and macroevolution.
How does an eye form? How does a fin form? ask ToE.

Re: What is macro-evolution?
Hi Jar,
What macro-evolution is has been questioned throughout this thread, ...
Well that is the heart of the question isn't it? There are so many definitions both from science and from non-science (particularly creationists) that it is easy to be confused or for two people to be talking about two different things.
... but it seems to me that macro-evolution is simply an artifact that depends on what is being observed; it is humans looking at two critters from a lineage that are each temporally and generationally distant.
It is an artificial artifact of our making merely to make a label to use in conversation.
It is just the sum of a long series of micro-evolutionary changes caused by repeated mutation and selection.
Yes, it is evolution accumulated from adding up the single generation observations of microevolution. 1+1+1+1+1+1+1+1+1+1=10 rather than 1+1=2.

Re: so can you define macroevolution or not?
Hi again Big_Al35
You are suggesting that the exceptions to the rule drive microevolutionary change? That was never my understanding. Exceptions to the rule are like lawless bandits where no real working foundation can be established. The result is confusion, chaos and misunderstanding. That's why I wanted to leave exceptions out of the equation for the time being. However, if you believe exceptions are the foundation of evolution then I was right when I said that we can't even agree on micro-evolution never mind macro-evolution.
In this case the rule was strict inheritance, and the exception were those cases where the pea plants were modified by mutation and thus did not fit in the neat boxes of Mendel's model.
So in this case those exceptions, being mutations, are part of what drives microevolutionary change.
Would you agree that they largely hold true then?
Of course, those would be the hereditary traits that are passed from generation to generation and form the homologies observed in patterns of descent.
But preservation of homologies are not part of the mechanisms of change, and Mendel's work was focused on the preserved homologies in his experiments.
But neither mutations nor preserved homologies are elements of the larger picture that is the macroevolution process, rather they are part of microevolution.
The topic is evidence for macroevolution.
Enjoy.

peppered moth thread
Hi again Big_Al35
That's fine but I often hear claims that grey moths turning into black moths is evolution in action. But surely this is just an existing homology which is being wiped out and therefore no evidence of evolution? It appears that you concur.
If this is what you hear then you are often being told falsehoods. If you want to discuss this further or just read what is actually shown by the peppered moths ...
See the Peppered Moths and Natural Selection thread for the details.
As it is off-topic here.
Message 139: I think we need to be clear here.... we have already cited several different avenues for change.
1) mutations resulting in new beneficial homology (good genes)
2) mutations resulting in new detrimental homology (damaged genes)
3) mutations resulting in new neutral homology (new alleles)
4) mutations that don't result in new homology but are beneficial
5) mutations that don't result in new homology but are detrimental
6) mutations that don't result in new homology but are neutral
7) traits that suddenly appear according to laws of inheritance
8) traits that suddenly disappear according to laws of inheritance
9) natural selection acting upon traits governed by the laws of inheritance
All of these are examples of micro-evolution not macro-evolution. Therefore Mendel's laws do fall into the category of micro-evolution even though you claim that's not the case.
Perhaps this could be a good start for a new topic: Evidence for the mechanisms of Microevolution

macroevolution is originally a scientific definition of a process
Hi idscience,
I am not surprised.
Are you willing to learn?
Lots of arguing about definitions, and species, and how that proves macro-evolution. convenient for evolutionary scientists to have defined macro-evolution so that it can be proved so easily. ....
Macroevolution is not proved, it is a process that is observed and named. Because it is observed before it is named, the evidence that was observed demonstrates that the definition fits the observation. This is not a difficult concept.
Science defines terms for use in discussions of the science, and this means that they would necessarily define terms to mean things that are actually observed.
Perhaps you could try to go back and find who first used the term macroevolution and what it was originally used for.
quote:
Macroevolution - Origin of the term:
Russian entomologist Yuri Filipchenko first coined the terms "macroevolution" and "microevolution" in 1927 in his German language work, "Variabilitt und Variation". Since the inception of the two terms, their meanings have been revised several times and the term macroevolution fell into limited disfavour when it was taken over by such writers as the geneticist Richard Goldschmidt (1940) and the paleontologist Otto Schindewolf to describe their orthogenetic theories.[5] ...
Have fun finding the original definition ... however it should be noted that what is critical is how it is used in science today. How creationists use or misunderstand the term is irrelevant to what the scientists discuss with the term used by their definition. If you want to discuss science, then learn the meanings and use the terms of science.
... It has been more important to satisfy the minimalist definition of macro-evolution than to offer the evidence for the overiding principal for it, large morphological changes occur. ...
We gave you what you asked, if that is not the answers you wanted then you asked the wrong question.
Do you want to see how large morphological changes occur and the evidence for them then you are asking for evidence of how the ToE explains changes observed in the fossil record and ends up with the diversity of morphological differences we see in the world today.
Of course, first you are going to need to define what you mean by "large morphological changes" as this is not a quantified description.
Do you think that the morphological differences between a house cat and a red fox are "large morphological changes"? Do you think they are differentiated by just a little or by lots of macroevolution?
Do you think a webbed foot is a "large morphological change" when the parents don't have webbed feet?
You might want to read through Dogs will be Dogs will be ??? or MACROevolution vs MICROevolution - what is it? and see if you can formulate your question clearly.
... The only defence offered for that is, "enough time will do it". The rest is arguing about speciation, which many believe is just variation or micro-evolution. The only difference is evolutionary scientists decided it wasn't.
Well can you deny that many generations add more evolution than single generations? Here's Pelycodus again:
How many generations do you think are shown there?
Speciation can be taken as the boundary between microevolution and macroevolution, and this would be consistent with microevolution occurring within breeding populations. Generally, however, scientists don't worry so much about macro and micro, and prefer to talk about evolution and the resulting cladistic patterns.
What happens with speciation events is a division of the breeding population into two or more populations, each then free to evolve independently by microevolution within their respective breeding populations.
I have read, speciation is defined as an isolated repoductive community. Although many separate species are able to reproduce with each other. I guess that doesn't matter.
Are zebras and horses different species? Can they be bred in captivity? Do they willingly breed in captivity? Do they willingly breed in the wild?
Able to be artificially bred in captivity does not mean willing to breed.
No one seems interested that the best microbiology has been able to accomplish is 1+1=2. No one is interested in the boundries and limitations of mutational changes, or that just about all the changes involve loss of information. Information loss, cannot build anything new. Just faith that enough time can do the job.
Perhaps that's because we've seen the evidence for 1+1+1+1+1+1+1+1+1+1=10 and know that your assertions are absolutely false.
Of course you could try to prove me wrong by actually providing evidence of this mythic mutational barrier. See "Macro" vs "Micro" genetic "kind" mechanism? -- an 8 year old thread that asks for this mechanism, but which no creationist nor idologist has provided. Be the first.
Anyone could look at old fossils and make relational assumptions. Especially if they are commonly designed.
And those assumptions can be tested by applying the methodology of cladistics, and by having separate groups make simultaneous analysis and by comparing it with similar analysis using DNA.
Curiously this has been done, extensively. Guess what? They confirm each other. Can you tell me why the results are the same if the process is subjective?
Oh, Ida pushes back divergence x of years, oh wait, Ida is just a lemur, never mind. Because evolution is a "fact", the relationships made between fossils are contrived. Trees, branches, divergence, is just an attempt to make sense of a premise that may very well be wrong.
But amazingly has not even been dented in over 150 years of attempts, both from creationists and scientists (scientists continually test their science, and one could make a big splash name for themselves should they show the theory is false).
I see nothing here, no evidence outside variation to suggest evolution can invent new organs, limbs, or body plans. The cornerstone, and backbone of this belief, is TIME. Certainly over billions of years anything can happen, right!
Thanks guys for the excersize in futility. I was hoping to read something new but its the same ol thing, variation has no limits time cannot overcome.
No, we thank YOU for the exercise in futility, trying to answer questions for someone who (a) doesn't understand what he is asking, (b) is unwilling to learn when his misunderstandings are explained, and (c) had his mind made up before hand.
My blog on this subject is called "evolution's shell game"WordPress.com — Get a Free Blog Here
Thanks, I'll add it to the thread Scientific vs Creationist Frauds and Hoaxes and note that this is another site spreading false and ignorant information to delude gullible people.
I believe the science of mapping ancestrial descent is in the mess it is because the theory is flawed. Paleo's homologies are not matching molecular homologies (some are some are a mess), and even within molecular homologies branching is conflicting. IE: DNA and RNA. the once simple tree is now discribed by scientists as a "mosaic", or a "thicket" because there is no clear line of descent. The seemingly all over the place similarities are better explained by common design. What may look related, is only because of the similar design features.
And yet, interestingly, science and scientists are not perturbed. Perhaps because there is not the major issue you seem to think there is.
Dawkins once said that nature only has the appearance of design. Maybe, because it was. I know I have not changed anyones minds here and that wan't my goal anyhow. Most of you if not all think I am an IDiot, conspirator who just wants to kill science and force religion on school students. That I have not one cintilla of evidence to believe what I say I believe. It's all eithre a ploy, or I am just plain stupid. I have heard is all before, many times.
Let me leave on this note:
I can see the logic in believing in common ancestry. There are some complelling evidences. IE: progression of fossils in strata, variation in the species, common looking features in the fossil record, and similar genome homologies. I am not saying your all nuts. Many very smart people believe common ancestry to be logical, and I can see how they get there.
I however, don't get all the way there when adding in common design. Design theory is more compelling to me given the barriers mutation and change have come up against over 150 years to trying to engineer changes in labs.
Again, you have provided absolutely no evidence for any barrier. Your assertion is based on your opinion. You want to see common design, so you even claim you see it for the bat and bird wing, in spite of evidence that the homologies between bats and quadrapeds and the homologies between birds and quadrapeds are greater than the homologies between bats and birds.
The evidence of nested clade hierarchies is evidence against common design.
The evidence of homology distribution between species with convergent evolution (like the bird and bat wing) are evidence against common design.
The fact that scientists have not been able to produce anything even close to changes beyond "speciation", ...
Multiple speciation events, formation of the nested clade hierarchy have been done, and they are changes beyond "speciation" (as defined and used in science), so again you either have failed to comprehend the evidence or are ignoring it.
... Not just new species, used in the context that they are actually new animals. The definition of species doesn't even require a morphological change. ...
And?
Your apparent failure to understand that science uses terms the way they define them to be use to clearly discuss the science, rather than the way some underinformed layman uses them, is not a problem for us.
... So arguing that macro-evolution is proven by speciation doen't do much for me ...
It isn't proven, it is defined to start with speciation and the development of nested clade hierarchies. The picture above for pelycodus meets this definition, therefore it is an example of the process defined by the term macroevolution.
... Especially when the definition is inconsistant anyways. IE: interspecies breeding does occur, so how can species be defined as an isolated reproductive community. ...
They can be isolated by behavior, geology, timing, and a number of other barriers to breeding in the wild.
I respect everyone here, I respect the conclusions made here and the logic used in getting there. I have an opposing position which makes me your opponent, not your enemy.
You have an opposing position that you have not supported, that is the "enemy" -- not you.
Thanks everyone, I enjoyed the discussion.
Feel free to come back, particularly if you have any new questions.
Enjoy.

Summary: Macroevolution is defined as a process that was already observed.
To idscience and other participants,
The early part of this thread was taken up by many repeated attempts to get idscience to define macroevolution in his words, to get a better idea of what he was talking about.
The term macroevolution has many misunderstandings and misinterpretations, especially among those not well versed or knowledgeable in the field of evolution.
The reluctance of idscience to define this term reveals such a lack of knowledge. Other comments reveal a poor understanding of the use of terminology, theory and proof in science. This is unfortunate, and I think it is a sad commentary on our education system for idscience to be in this position.
Microevolution is defined as a process that was already observed.
Similarly, Macroevolution is defined as a process that was already observed. This means that it is neither an hypothesis or a theory, but a fact by definition. If I define 'pencil' as a tube with a center stick of a compound that leaves an observable, erasable track on paper, then observing such an object does not prove that the hypothesis of 'pencil' is true nor is it proof that 'hypothetical pencils' exist.
The confusion of macroevolution with the theory of evolution and the misunderstanding of what scientific terms, hypothesis and theories are used for and do is exemplified by the following from idscience:
Message 67: macro evolution has to be able to produce novel morphology.
A wing has to be built from a limb,
a leg from a fin.
Macro-evolution has to demonstrate how the increase of information occurred.
It is not the function of the pencil to demonstrate how words are written, nor does a pencil have to draw a picture. It is a tool. The term macroevolution is a tool for understanding the variety of life.
The job of theories and hypothesis is to explain observed objective evidence. It is the job of the ToE to explain how a wing can be developed from a limb, how a limb can develop from a fin, how increased diversity occurs, including more complex forms from less complex forms and less complex forms from more complex forms.
The ToE is capable of doing this.
Whether these developments are considered "novel" is irrelevant to the process, as non-novel developments also need to be explained.
When creationists and idiologist ask for explanations of novel morphology they are asking about something other than the occurrence of macroevolution, as macroevolution occurs many many times without novel morphology (a wing from a limb uses the same bones and other structures, just adapted by microevolution into a different pattern), and even after lots of macroevolutionary steps, the differences between, say a cat and a fox, are not that remarkable.
Its like they ask for an example of how a pencil is made, and when you show them the process of gluing wood around a stick of graphite, they say that it doesn't explain mechanical pencils.
They are asking these questions because they think, or they have been told, that evolution cannot explain them.
More telling is that the formation of new structures is not by the process of macroevolution but by the process of microevolution.
Due to the continued failure of idscience to provide a definition of macroevolution the admin stepped in (Message 79) and defined macroevolution for this thread, to be used by all participants:
quote:
About the definition of macroevolution, for the purposes of this thread macroevolution is defined as evolution above the species level. A gray squirrel evolving into a red squirrel is macroevolution. A fish evolving into an amphibian is macroevolution. A bacteria evolving into man is macroevolution. Included in this definition is the fact that such transformations require thousands to millions to billions to even trillions of generations, depending upon the degree of change.
Color added for emphasis.
Once this definition was provided several examples of macroevolution were provided.
Message 81: In this regard this:
Shows the evidence for macroevolution occurring several times in the fossil record for Pelycodus.
Do we see evolution above the species level? Yes, several times. We see Pelycodus ralstoni evolving into Pelycodus mckennai as one instance at the bottom and the evolution of Pelycodus jarrovii into Notharctus as another instance at the top.
Do we see speciation? Yes, several times. We see the speciation event that divides the Pelycodus trigonodus parent species into the Copelemur feretutus and Pelycodus ebditus daughter species and the speciation event that divides the Pelycodus ebditus parent species into the Pelycodus jarrovii and Pelycodus frugivorus daughter species.
Do we see the formation of a nested hierarchy? Yes, from the original Pelycodus ralstoni at the bottom we have several branches of a nested hierarchy that looks like this:
                         |
                         ^ a
                        / \
                       /   \
                      /     \
                     /       ^ b
                    /       / \
                   /       /   \
                  e       d     c 
Do we see an increase in the diversity of life? Yes, where originally we had one breeding population Pelycodus we now have three: Pelycodus Copelemur and Notharctus.
Do we see the formation of higher taxon levels than species? Yes, where originally we had one species Pelycodus we now have three genera: Pelycodus Copelemur and Notharctus that together form a family.
And this is but the tip of the iceberg of evidence for macroevolution.
Indeed, we could add foraminifera where many many many examples of the hierarchis of nested clades and macroevolution are preserved in a virtually complete fossil record. This even includes the formation of morphology that did not exist before (and hence is "novel" by normal definitions of the term).
Also see Message 84 and Message 85. There are many instances of macroevolution both in the fossil record and in the genetic record.
Unfortunately, idscience seemed reluctant to accept that his use of macroevolution was wrong, as we see in his first post following the admin's definition:
Message 93: Another post with no information. The def of macro is changes above the level of species. According to many evolution experts, speciation is macro-evolution, so that is no help. Does not get me to my questions.
photoreceptor pathway?
flagellum motor?
how are they built by a blind undirected process?
... ie - how does it explain a mechanical pencil ...
Amusingly, these questions are (a) old creationist pratts, and (b) about how the theory of evolution explains these formations, which it does with microevolution and the adaptation of existing structures, not by de novo creation of new structures.
Thus idscience still does not understand what he is asking about, even after it is explained to him, several times, by several people.
It is at this point, where repeated attempts to explain things to people that I consider the effects of cognitive dissonance on firmly held beliefs:
Cognitive dissonance - (Wikipedia, 2010)
Cognitive dissonance is an uncomfortable feeling caused by holding two contradictory ideas simultaneously. The theory of cognitive dissonance proposes that people have a motivational drive to reduce dissonance by changing their attitudes, beliefs, and behaviors, or by justifying or rationalizing them.[2] It is one of the most influential and extensively studied theories in social psychology.
A powerful cause of dissonance is an idea in conflict with a fundamental element of the self-concept, such as "I am a good person" or "I made the right decision". The anxiety that comes with the possibility of having made a bad decision can lead to rationalization, the tendency to create additional reasons or justifications to support one's choices. A person who just spent too much money on a new car might decide that the new vehicle is much less likely to break down than his or her old car. This belief may or may not be true, but it would reduce dissonance and make the person feel better. Dissonance can also lead to confirmation bias, the denial of disconfirming evidence, and other ego defense mechanisms.
A curious side effect of cognitive dissonance is that (initially anyway) the belief is held even more firmly while the denial of disconfirming evidence and attempts to discredit messengers and similar behavior increases. The conclusion is not 'whoa, that may be right, let me investigate' but 'whoa, that must be wrong, I must disprove it' leading to seeking out evidence with confirmation bias, rather than an open-minded skepticism.

Ignorance Is No Crime
by Richard Dawkins
"It is absolutely safe to say that if you meet somebody who claims not to believe in evolution, that person is ignorant, stupid or insane (or wicked, but I'd rather not consider that)." I first wrote that in a book review in the New York Times in 1989, and it has been much quoted against me ever since, as evidence of my arrogance and intolerance. Of course it sounds arrogant, but undisguised clarity is easily mistaken for arrogance. Examine the statement carefully and it turns out to be moderate, almost self-evidently true.
By far the largest of the four categories is "ignorant," and ignorance is no crime (nor is it blissI forget who it was said, "If ignorance is bliss, how come there's so much misery about?"). Anybody who thinks Joe DiMaggio was a cricketer has to be ignorant, stupid, or insane (probably ignorant), and you wouldn't think me arrogant for saying so. It is not intolerant to remark that flat-earthers are ignorant, stupid, or (probably) insane. It's just true. ...
I recommend reading the whole article several times, particularly if you are someone who does not accept evolution.
Ignorance is curable by learning the truth. Of course the ignorant person has to be willing to learn. He concludes the article with:
quote:
I don't withdraw a word of my initial statement. But I do now think it may have been incomplete. There is perhaps a fifth category, which may belong under "insane" but which can be more sympathetically characterized by a word like tormented, bullied, or brainwashed. Sincere people who are not ignorant, not stupid, and not wicked can be cruelly torn, almost in two, between the massive evidence of science on the one hand, and their understanding of what their holy book tells them on the other. I think this is one of the truly bad things religion can do to a human mind. There is wickedness here, but it is the wickedness of the institution and what it does to a believing victim, not wickedness on the part of the victim himself. The clearest example I know is poignant, even sad, and I shall do it justice in a later article.
Of course, tormented would be one of the effects of cognitive dissonance. I call this final category deluded and agree that it is sad to see occurring with the frequency I see here. It seems that our school system has failed a lot of people.
de•lu•sion -noun (American Heritage Dictionary 2009)
  1. a. The act or process of deluding.
    b. The state of being deluded.
  2. A false belief or opinion: labored under the delusion that success was at hand.
  3. Psychiatry A false belief strongly held in spite of invalidating evidence, especially as a symptom of mental illness: delusions of persecution.
Like ignorance, delusion(1b) and delusion(2) are curable by learning the truth, as long as the ignorant person is willing to learn.
However, brainwashed is a bit stronger than delusion(1b), and would be harder to cure, as this can interfere with the willingness to learn, and pushing the person towards delusion(3), which is the wickedness of the brainwasher.
What is the tactful word for the concept of telling deliberate untruths? Would mendacious work do describe this paragraph accurately? To mild I think.
Try ignorant, stupid, insane, wicked, ... or deluded.
Passing on misinformation that you have been deluded into believing is not necessarily mendacious or wicked. It is sad. And it is sadder still when the victim is unwilling to learn.
Deception is all creationists have. I don’t respect mendacity. idscience, I don't respect you as a person, neither your deception, at all.
Harsh. I am disappointed, disappointed by the unwillingness to learn and the retreat to repeated assertions (as if that makes them more real).
I am saddened and disappointed each time I see such recalcitrance on these threads. If our schools cannot teach science, they should at least teach open-minded skepticism and encourage a willingness to learn more.
Finally, idscience asked if he could quote me on his website and my response was:
quote:
Third, what you can quote on your site is this:
(1) The process of Microevolution involves the change in the frequency distribution and composition of hereditary traits within breeding populations from generation to generation, in response to ecological challenges and opportunities.
Mutation can cause change in the composition of hereditary traits carried by individuals of a breeding population, but not all mutations do so. In addition there are many different kinds of mutations and they have different effects (from small to large).
Natural Selection and Neutral Drift can cause change in the distribution of hereditary traits within the breeding population, but they are not the only mechanism that does so.
The ecological challenges and opportunities change when the environment changes, the breeding population evolves, other organisms within the ecology evolve, migrations change the mixture of organisms within the ecology, or a breeding population migrates into a new ecology. These changes can result in different survival and reproductive challenges and opportunities, affecting selection pressure, perhaps causing speciation, perhaps causing extinction.
Mutations of hereditary traits have been observed to occur, and thus this aspect of microevolution is an observed, known objective fact, rather than an untested hypothesis.
Natural selection and neutral drift have been observed to occur, along with the observed alteration in the distribution of hereditary traits within breeding populations, and thus this aspect of microevolution is an observed, known objective fact, and not an untested hypothesis.
(2) The process of Macroevolution involves the development of new species, the formation of nested hierarchies of descent of new species from common ancestor populations, and an increase in the diversity of life.
This looks at the continued effects of microevolution over many generations, where the accumulation of changes from generation to generation become sufficient for new species to develop that are different from the ancestral parent populations. This lineal change in species is sometimes called phyletic or arbitrary speciation.
(a) The process of Phyletic Speciation involves a lineage of descent from an ancestor population accumulating sufficient differences through microevolution that, when compared to the ancestor population, it would appear to be a different species.
This is sometimes called arbitrary speciation because it is difficult to agree on where the line of division from one species to the next occurs, how many times this occurs in a given lineage, and because the definition of species itself is fairly arbitrary.
The amount of change in phyletic speciation can be compared to the changes seen in divergent speciation between parent (ancestral) populations and the daughter (descendant) populations as a check on the amount of change to be considered.
(b) The process of Divergent Speciation involves the division of a parent population into two or more reproductively isolated daughter populations, which then are free to (micro) evolve independently of each other.
The reduction or loss of interbreeding (gene flow, sharing of mutations) between the daughter populations results in different, independent, evolutionary responses in the daughter populations to their respective and different ecological challenges and opportunities (including the existence and impact of the other daughter population/s on survival).
Independent evolution within each subpopulation results in divergence of the subpopulations from each other. Divergent speciation forms a branching pattern of descent from a common ancestor pool, and results in added diversity of species. Further instances of divergent speciation adds further to the branching pattern and results in a nested hierarchy pattern.

Phyletic speciation with the development of new species by extended microevolution in a lineage of descent has been observed to occur, and thus this aspect of macroevolution is an observed, known objective fact, and not an untested hypothesis.
Divergent speciation with the development of new species by the reproductive isolation of daughter populations has been observed to occur, and thus this aspect of macroevolution is an observed, known objective fact, and not an untested hypothesis.
The formation of nested hierarchies of descent from common ancestor populations has been observed to occur, and thus this aspect of macroevolution is an observed, known objective fact, and not an untested hypothesis.
The addition to diversity by increasing the number of species and higher groupings has been observed to occur, and thus this aspect of macroevolution is an observed, known objective fact, and not an untested hypothesis.
One single example that shows all of these processes in the fossil record is:
Conditions for quoting are (1) that it be quoted in full, (2) that it be properly cited as a reference and (3) that you give me irrevocable permission to edit your site and correct any errors you make (it could use some help anyway).
In Message 150 idscience says:
I will data mine the site for any new perspectives and information. I'll probably pop up again for another thrashing on another subject so your boys better keep up to date on current events, so I don't catch anybody with their "genes" down, sort o speak.
This is okay so long as comments are not taken out of context (as his first request to me was), which of course is the old creationist\idologist ploy of "quote mining".
Instead, I would prefer that idscience stick around and participate in other threads (several have already been recommended), and learn so that he can provide correct information in his own words.
This may be asking a lot ... as willingness to learn has not yet been displayed.
Enjoy
