Re: more evolved / less evolved
Take two species today and their last common ancestor. Quanitfy the differences in genomes between the current species and the ancestor. The species with more changes to its genome is more evolved than the other.
More divergent does not equal more evolved. Selection of already existing features is as much evolution as selection of new features.

Re: more evolved / less evolved
Everybody's really digging their heels in on this absolute claim of "no such thing as more evolved" and, I think that it can be seen as technically incorrect.
What seems to be confused is the process vs. the end result. Every lineage has been influenced by the process of evolution, but the end result of that process is different for each lineage.
As an analogy, if a random number generator spit out a series of numbers would the highest number be called the most random? Of course not. All numbers are equally random even if some numbers are larger than others. They are all products of the same process.
However, there is a term that does describe what people are trying to get at, and it is the term that scientists actually use. That word is "derived". A more derived species is one that has more changes than sister species as compared to the common ancestor. This would make modern bacteria less derived than humans since modern bacteria share more features with the common ancestor of bacteria and humans than humans do. Does that make sense?
I don't think so. Stasis is a lack of evolution.
False. The only way that stasis can occur is through evolution. Stasis is the selection of alleles found in previous generations. Without evolution the prevalence of alleles from previous generations would be swamped by variation found in each subsequent generation. Whether it is selection of new alleles or pre-existing alleles the process is the same: evolution.

Re: If Extinct then not transitional?
Falsifying TOE does not prove creation. Falsifying TOE as it stands now does not mean evolution did not happen either. What supports creation is based on research such as that by scientists like John C Sanford on entropy and other creationist dating methods and research.
Sanford's work is strictly anti-evolution. His model seeks to demonstrate that evolution working alone would result in genetic meltdown, therefore species could not have evolved. Period. Nowhere does Sanford run experiments that test whether or not species were magically poofed into being.
I would think that of all the branching that must have occurred over the last 8 million years that some of the now extinct branches should have survived, yet not been offered the environmental or adaptive influences or drift to advance them all the way to Homo Sapiens. Why are there none stuck in a evolutionary transitional form?
It is impossible for species to get stuck anywhere since every generation has new mutations not found in any previous generation. Evolution doesn't stop. It continues in every lineage.
We can use the Romance languages (e.g. French, Italian, Spanish, Portuguese) as an example. All share a common ancestor which is Vulgar Latin. All language groups have acquired their own specific differences over time. None are a transitional form of the other, nor are they in-between versions of one langage and Vulgar Latin. Each language lineage diverged from the others and continued to change. At the same time, there are obvious homologies in each language that come from their common ancestral tongue. In order to find the "in between" stages you have to travel back in time along the lineage of each language.

Re: more evolved / less evolved
I'm talking about the end results.
The process is evolution. The end result is varying degrees of divergence.
Can't we say that some species have been influenced more than others? That they've gone through more changes?
Is Mecury more gravitated because it's orbit is more heavily influenced by the Sun?
Random thought: On a totally different aspect, what about species that are better adapted to their particular niche? Couldn't describing that as being more evolved to that niche make sense?
Nope. That is described by fitness. Species are more fit or less fit, not more evolved or less evolved.
ABE: Just thought of some better examples. Let's look at the camel and polar bear. If we put the polar bear and camel in the desert you would say that the camel is more evolved. If we put them both in the arctic you would say that the polar bear is more evolved. So how can the polar bear (or camel) be both more evolved and less evolved at the same time?
What I'd be judging is the output of number. The more varience between the numbers, the more random they would be.
It was only an analogy that is not meant to be strained this far.
On the other hand, what about a species that, for whatever reason, did not experience as much mutation as normal, and also had very little selective pressure.
That would only affect the speed at which populations change. They are still evolving, just as both Mercury and Pluto are orbitting the Sun through the same process, just at different rates.
Edited by Taq, : No reason given.

Re: If Extinct then not transitional?
Good analogy. I'll also point out that in your travel back in time along the lineage of a language, you'll never find anything like Latin-speaking parents waking up one day to find their children all speaking French.
This is true of each generation in both the French and Spanish lineages, clear back to the point where the languages diverged. At no point were children incapable of speaking to their parents, but the same can not be said of generations separated by longer time periods (try reading the Canterbury Tales in Old English). The difference is that each lineage acquired different changes. It is the divergence due to lineage specific changes over time that moved the two languages apart, just as it does in biology.
Languages actually make for a good analogy when discussing evolution. It isn't a perfect analogy, but then no analogy is. For reference, wiki has a nice diagram of the Romance Languages here.

Re: more evolved / less evolved
Alrighty then.
Well, having the phrase "more derived" to better describe the concept than "more evolved" does will work for me, so thanks again for the replies.
I'm convinced that "more evolved" isn't good phraseology so I'll replace it with "more derived" in the future.
Just so you don't feel picked on, I have heard biologists on TV programs talking about more and less evolved lifeforms. I wish they wouldn't do it, but they do nonetheless. If you were to push them on the topic they would probably agree that the phrasing is incorrect. The problem is one of communication. Scientists try to adopt a more colloquial vocabulary when talking to the public, and in doing so they can misrepresent what science actually says.
More on topic, the term "ape" is colloquial. In scientific papers scientists will not use the term ape, at least not in my experience. Most often, they will usually just use the term "primate". A discussion on the every confusing classifications can be found here.

Re: More evolved?
Indeed G is meant to be homo erectus. The skull presented in your picture is an ape. However if they would have pictured Turkana Boy he is fully human. Turkana boy is classified as eragaster sometimes. From A-G are simply varieties of apes.
What criteria are you using to differentiate between ape and not ape in those skulls?
What features must a fossil have in order for you to consider it as intermediate between humans and non-humans?
So what you actually have is a good representation of apes and the sudden appearance of mankind, only missing Turkana Boy, because that would throw the whole graduation thing into disarray for evolutionists. Well done!
Until you share with us the criteria you are using you can claim no such thing.

Im not lying. This my opinion and belief.
So what do you call it one someone's opinions and beliefs are directly contradicted by the facts, but they keep pushing those opinions and beliefs as if they were not contradicted by the facts?
I would call this dishonesty. What about you?

Re: More evolved?
In the case of humans Ardi, although not the missing link, is proposed as an intermediate. Ardi is now being refuted by some reasearchers as not being in the human line.
So what features must a fossil have in order for you to consider it transitional? How did you determine that the fossils in the picture below were not transitional?
What criteria are you using?

Re: More evolved?
If ones beliefs being contradicted by the facts means someone should give up their beliefs then you should not be an evolutionist.
Which facts are these?
What is dishonest is the evolutionists claim that the evidence for human ancestry with todays apes is solid. It isn't.
Why isn't it solid?

Re: More evolved?
The erectus fossil is only an ape. Turkana boy, however is human, and was not illustrated as it throws the nice crap line out of whack.
What criteria are you using to determine whether a fossil is ape or human? What characteristics must a fossil have in order for you to accept it as transitional?
I have posted evidence showing that similar morphology is NOT a sign of ancestry, hence your so called 'evidence' is not more than a wish and hope list put forward as flavour of the month.
So you are saying that if humans and other apes do share ancestry that we should not find any similarities between us and and other apes? Similarly, are you saying that we should not find transitional fossils if evolution is true?
You need faith to believe than any of these fossil skulls have anything to do with the human lineage.
It doesn't take any faith to conclude that these fossils do have a mixture of modern human and basal ape features just as one would expect to find if evolution is true. These fossils are used to test the theory, and the theory passes those tests. If you found a fossil with a mixture of ape and dog features then you would falsify the theory. See how that works?
The link above is not about whom is right or wrong but simply demonstrates that the vast majority, at least, of your support for human ancestry is questionable and refuteable.
Could you discuss this material in your own words, please?
"But researchers led by David Reich of Harvard Medical School in Boston, Massachusetts, now calculate that the split may have occurred no more than 6.3 million years ago, and possibly as recently as 5.4 million. That would make Touma older than the time of the split. "
H. erectus is younger than 6.3 million years, so this doesn't disqualify H. erectus or H. habilis, H. ergaster, A. afarensis, etc. All of these fossil transitionals are younger than the 6.3 million that you posted here.
In other words these researchers have no clue and are best guessing and hoping at best.
So what features must a fossil have in order for it to be transitional in your eyes? Why can't you answer this question?

Re: More evolved?
If ones beliefs being contradicted by the facts means someone should give up their beliefs then you should not be an evolutionist.
So what facts contradict shared ancestry between humans and other apes?
The evolutionist paleontologists C. A. Villee, E. P. Solomon, and P. W. Davis admit that man emerged suddenly on Earth-in other words with no evolutionary ancestor before him-by saying, "We appear suddenly in the fossil record."
Please cite their peer reviewed papers so that we can discuss this.
What is dishonest is the evolutionists claim that the evidence for human ancestry with todays apes is solid. It isn't.
The genetic evidence is irrefutable. One of the prime examples is orthologous endogenous retroviruses (ERV's) as discussed in this peer reviewed paper:
Given the size of vertebrate genomes (>1 109 bp) and the random nature of retroviral integration (22, 23), multiple integrations (and subsequent fixation) of ERV loci at precisely the same location are highly unlikely (24). Therefore, an ERV locus shared by two or more species is descended from a single integration event and is proof that the species share a common ancestor into whose germ line the original integration took place (14).
Just a moment...
As it turns out we share tons of ERV's at the same location in our genome. This is the smoking gun evidence of shared ancestry.
Do you notice how I cite peer reviewed scientific papers instead of websites run by crackpots? See how that works?
And you still haven't answered my question. What features must a fossil have in order for you to consider it transitional between modern humans and our common ancestor with chimps?

Re: More evolved?
"ScienceDaily (June 29, 2011) Modern humans never co-existed with Homo erectus -- a finding counter to previous hypotheses of human evolution -- new excavations in Indonesia and dating analyses show. The research, reported in the journal PLoS ONE, offers new insights into the nature of human evolution, suggesting a different role for Homo erectus than had been previously thought."
I never co-existed with my great grandfather. Does this mean that my great grandfather is not one of my ancestors?

Re: More evolved?
Really most of your Homo Erectus fossils are nothing more than a variety of gorilla, with a human thrown in here and there eg Turkana boy and possibly the little skull cap from Java man.
A gorilla? Really? Here is a gorilla skull:
Notice any differences?
