It doesn't. It's not supposed to. Simplicity is the common denominator between us all.
quote:
Well if it isn't useful for classifying forms of life, what is it good for?
By saying 'Simplicity is the common denominator between us all' I was referring to common sense. In order to understand the complex you must first understand the simple. To understand the simple you need commmon sense. Uderstanding the complex is what takes intelligence. In other words what this "system of simplicity" does is to help show us the simple leading up to the complex.
quote:
I wasn't aware that 'relatedness' could 'state' anything,
but it certainly implies linkage between living things, by definition.
So you're weren't aware that relatedness could state but you're aware that it could certainly imply. Of course, wanting to keep on the subject, I agree. I never said I didn't.
quote:
you can now say that organism A is more related to B than to C.
What is so useful about that
quote:
So we are no more related to monkey kind than we are to 'algae kind'or 'bacteria kind'? I am sure we all have some very similar enzymes and other proteins in common, but the number of differences are few between man and monkeys. In fact "Studies indicate that humans and chimps are between 95 and 98.5 percent genetically identical. So similar, in fact, we probably belong in the same Genus.
Same genus? I wouldn't be surprised, but we're not the same species. That is the whole point. Though we have similarities we're not the same. Yes we are more closely related to monkeys than algae. But we are still man kind and monkeys are still monkey kind.
quote:
You need to read more outside of your Sunday school assignments. See:
Chimps Belong on Human Branch of Family Tree, Study Says
And you read national geographic? The people that said a theory is'nt really a theory but a fact accepted over time? Just to get people to believe their so called "science"?

Is Homo erectus man kind, monkey kind or Homo erectus kind? What are Australopithecines?
Have you ever seen a Homo erectus besides in the text books and in magazines and plaster exhibits in Smithsonian? How do you know they ever existed. No one ever even found a comlete skeleton. As for Australopithicines they could possibly still be alive in Africa. I've never seen them but I do study Cryptozoology and it is a possibility. That is if they ever existed at all.

Well, if it has no predictive value or a basis in anything other than a simplistic, child's notion of what 'kinds' of things are related, then is is simply a fun thing to believe, but nothing more than that.
quote:
I was speaking metaphorically about commmon knowledge.
Great. So what does this have to do with Biology?
It's a story you tell but is otherwise not useful.
quote:
Metaphors can be useful if you figure it out. It saves a lot of complicated explanation that, other than the point, is usually not necesary.
Science does not proceed through the use of methaphor and simplistic explanations.
Science deals in predictions, evidence, testing, and very, very detailed-oriented, meticulous work.
So, should we stop using Chimps and other primates in medical testing because we have no way of determining how closely related various species are?
quote:
No. I never even remotely indicated that.
Yes, you most definitely did when you said in message 13 of this thread:
quote:
What you're talking about is micro-evolution, the only testable, observable, and proven aspect of evolution (also known as a variation). When fish, or insects inter-breed it may form a new species but it's still a fish, it's still an insect, it's still the same kind of animal. Science is observable and testable. Macro-evolution is not.

If you are denying the reality of macro evolution, and you declare that Humans and chimps are separate "kinds" and I am guessing you also claim they are not closely related, then you are most definitely suggesting that using chimps and other primates in medical research is useless.
If humans and chimps aren't the same "kind", then the research should be useless. At least, using primates shouldn't be regarded as being the next closest thing to testing humans.
Right?
quote:
Actually I was agreeing that humans and animals, some animals more than others, have similarities but they are not the same species,
Well, no, of course we aren't the same species, but remember, you are the one who said that there was no such thing as macroevolution.
If there's no such thing as macroevolution, then you need to reject the entire field of genetics, because it certainly does point to macroevolution having happened.
Anyway, maybe you should provide a definition of the following; "kind", "macroevolution", and "microevolution".
For good measure, why not throw in a definition of "descent with modification", too.
quote:
and until a reptile gives birth to a bird,
...which the ToE never, ever predicts.
quote:
or a hyrax gives birth to a suvivng mutation that looks like a horse
...which the ToE never, ever predicts.
Where on earth did you ever get the idea that this is how evolution works? You have some rather major misconceptions that a little information should rectify.
Please, read this basic overview of how evolution actually works.
BTW, I suspect that you are thinking of hyracotherium, the oldest known ancestor of the horse. The hyrax is not closely related to the horse lineage, but to elephants.
quote:
I will not believe evolution.
You clearly have a very distorted idea of what evolution actually is.
Perhaps, before you handwave away the underpinning Theory of most of modern life science, including Biology, Paleontology, Genetics (including Population Genetics), and much of the science that modern medicine, Agriculture and Animal Husbandry is based upon, perhaps you might consider making an effort to understand what it is you are rejecting.
You know, just to be safe.
quote:
Furthermore I will believe the oldest document until it is proven wrong. That document is the Bible.
The oldest document is not the Bible.
link
Sumerian, the oldest known written language in human history, was spoken in Mesopotamia (modern Iraq and peripheral regions) throughout the third millennium BC.
The Code of Hammourabi is probably the oldest known document.
quote:
It is the only document that says the earth is round way before Colombus figured it out.
1) Columbus didn't "figure out" that the Earth was a sphere. This was known by the Greeks through Pythagoras, Aristotle, and Ptolemy.
Unfortunately, once the anti-intellectual, Church-led Dark Ages settled into Europe, the strides in science and learning the Greeks had made were discarded in favor of superstition. (This thankfully did not happen in the Arab world, which is where Europe rediscovered the Greek texts during the Age of Enlightenment which followed the Dark Ages. Sadly, it seems that much of the Arab world is now repeating the same mistakes of anti-intellectualism and religious extremism that the Europeans made 1000 years ago.)
2) The Bible clearly says that the Earth is round, yes, but like a disc, with a dome-shaped firmament over it into which the stars are permenantly "set". Indeed, this Biblical view is exactly why it was thought that one would be in danger of sailing "off the edge of the Earth" if one ventured too far out to sea.
Finally, I notice that you didn't answer one of my questions, so perhaps you missed it.
Do you accept that DNA paternity tests are reliable and accurate?
Why or why not?

OK, here is my problem with the above.
You say that my housecats and a Siberian tiger are both "feline kind", correct?
You also say that humans and chimpanzees are NOT the same "kind" but "human kind" and "monkey kind".
The problem is that even though my housecats and a Siberian tiger have much more dissimilar genetic codes compared to humans and chimpanzees, you lump the first two together in the same "kind" and separate the second two into seperate "kinds".
This doesn't seem to make much sense as a classification system, because it isn't consistent.
This is why I asked if we were to discard genetic similarities when deciding what animals belong in what "kind" group.
If it is simply arbitrary, then it is useless.
(BTW, scientists consider both humans and chimps "apes", not monkeys. Monkeys have tails and apes do not, among other major differences such as intelligence, social structure, use of tools, and the presence of a culture)

I haven't gotten to all your questions yet. If you haven't noticed I already have about a zillion questions to go through from the second page. I don't have 6 hrs to spare going through all these questions you probably already know the answer to.

incorrect. I never said that either. I'm not sure where you got that idea. Apes, monkeys, I thought about specifying the difference but I didn't think we were getting that technical.

Mistaken sources
Some theories state that evolution happened quickly like in the case of reptiles and birds
You should not phrase this as a firm statement. When you are unsure of the subject you are discussing and someone with, perhaps, more knowledge suggests you have misconceptions you should respond with something like:
I read, in such and such a place, that evolution happened quickly in the case of reptiles and birds.
or
I thought that this was supposed to have happened quickly.
This gives the idea that you aren't so sure of your "facts" and are ready to be corrected.
In each case it would make sense for you to fill in a few more details such as were you read it. As for "quickly" you might want to be sure that you have a number on the time scale involved so others can understand what you mean by quickly.
What you have posted simply suggests that you have reached a conclusion without having,really, any facts on which to base a conclusion. This is neither good decision making or a very good base for learning new things.

Columbus didn't "figure out" that the Earth was a sphere. This was known by the Greeks through Pythagoras, Aristotle, and Ptolemy.
the Bible was still around back in the time of the philosophers or whatever you prefer to call them.
There are too many questions flying around. Let me make my point clear
Macroevolution-Evolutionary change involving large and complex steps resulting in a different KIND of animal
Microevolution- a change within a single species resulting a different species or subspecies.
kind- if it looks like a housecat it's a house cat. If it looks like a tiger it's a tiger if it looks like an ape its an ape if it looks specifically like a human it's a human
What I'm saying is that you are talking about micro evolution not macro.

"Quickly" in evolutionary terms involve many, many tens, even hundreds of thousands of years, intead of many millions of years.
Nowhere, ever, does the ToE posit that an individual of one species will give birth to a completely different species with many very dissimilar behavioral and physical differences, which is exactly what you said it did posit.

There is also no rush. Just indicate when it is that you expect to be able to reply.

So, what "kind" are my housecats and what "kind" are Siberian tigers, and why do you put them in the "kind" category that you do?
