Will you concede that domestic animals evolve through selective breeding? A poodle never existed in nature. It was bred into existence by people. Why is it such a stretch of the imagination to suppose that such a thing can happen randomly in nature?

Variation is observed. Evolution is not. It is a leap of faith to say that because variation happens, evolution happens. You may as well say that because Chevys have different models, they must have trains and planes too.

So explain that over millions of years we are THE ONLY intelligent being on the planet (aside from cats ;) ) I would think that some animal over the past years hasn't come even close to developing intelligance.

We are the most intelligent species on the planet, but we're not the only intelligent species on the planet.

Furthermore, there are plenty of ancestors/relatives of homo sapiens that were quite intelligent, even by human standards. Neanderthals, for example.

You're right. We've never created an entirely new species from selective breeding, but such a thing is not theoretically impossible. It's probably just a matter of time. It has been done through genetic engineering with new viruses and such. Are you saying that you'll become an evolutionist when it happens?

Actually, I'm not trying to prove that the Theory of Evolution is true. All I'm saying is that as a theory it's got a lot going for it, and it hasn't been disproven, even after 150 years. Nothing else explains the phenomenon of speciation, unless you just want to say "God did it", but that's a theological argument, not a scientific one. That's part of the problem in this debate. We're talking apples and oranges.

Evolution still doesnt explain anything about animals anyway.

Evolution explains why 'God' gave men nipples.. ;)

Still happening now. Look at how dim-witted lefties have stopped reproducing.

explain why they are not a credible source of science. explain how the pope is soooooooo all knowing.

Fine, if you want me to explain evolution, it simply put was some accident that created the universe, and some accident that happened on earth to create a little bit of life, such as bacteria. It was from that that we evolved using natural selection. I HAD to learn what evolution is in the BJU science books, IN THIRD GRADE. but it was tought as a theory, not fact. you guys have no proof that evolution exists, I have yet to see it, all you have is "evidence" from "millions" of years ago.

Well, first of all, I am a woman. And all you have to do is watch Jerry Springer to see the men fathering multiple children - lol.

True—now. But shift back hundreds of thousands of years and the situation changes drastically. In a world where human numbers were small and the war for existence was on-going and brutal, smarter individuals clearly had an advantage and no doubt succeeded in reproducing more often than dumber ones. Nowadays, we're so numerous and so successful as a species that intelligence gets downgraded a bit as far as fitness to reproduce is concerned. Still, when you were in high-school, would you have been attracted to a Beavis & Butthead-type guy or to a McGyver-type guy?

I guess it was a pretty steep evolutionary curve when God spoke us into existence...

LMAO

yup -ever adapting dogma is getting pretty deep in evolutionism churches... Next we will have the evolutionary big bang and or big spurts connected via missing links...

Observations are able to show the frequency of phenomena according to the times, places, populations or circumstances studied. In this way facts are discovered, but facts do not constitute a criterion for judging the truth of a complete theory lacking incomplete facts. The observation of the phenomena is certainly to be linked with truth; however, the linkage itself true does not by default impart truth into theory incorporating such...

Evolution explains why 'God' gave men nipples.. ;)

And why marsupial fossils can be found in Antarctica...

And why the sensors on our retinae face the wrong way (badly designed but still work)...

and... (repeat for thousands of curiosities of that evolution explains)

"This accelerated rate of evolution is consistent with the presence of selective forces in the human lineage that strongly favored larger and more complex brains. "

Beaurocracies. Nahhh!! that would have a retrograde impact. Human intelligence evolved DESPITE governments, not because of them.

I'm not sure that's quite true. IIRC, goldfish have been bred from coi over the last 1500 years or so and are now a completely species.

the group with the right set of genes for wings

Okay, I'll bite: How is it that a "group" gets the wing gene? I don't recall any suggestion in the theory that there exists a mass coincidental genetic deviation. This is the crux of the "complex" theory. If evolution is to be considered the way it is taught today you must believe the changes take place on a individual basis and so slowly that it is (nearly) imperceptible. It makes sense in the development of a giraffe's neck or the development of the human hand. System integration (the complexity of the human eye) is quite different.

Religion boils down to a question of faith as well. In terms of proof, science has more going for it.

Why do you correlate smartness with feebleness?

"It is perhaps the complex social structures and cultural behaviors unique in human ancestors that fueled the rapid evolution of the brain"

I believe it has more to do with the physical environment. For example, in an ice-age environment, selection pressure is at its strongest. Only the most intelligent and those who are able to cooperate with one another will survive and reproduce. It isn't a matter of smart people having more kids; it is a matter of stupid people dying off.

Culture or social interaction may explain verbal intelligence, but it does not explain logic, mathematics, abstraction, and visual-spatial abilities.

The wing example was used to make the point that some genes take a lot longer to saturate a gene pool than others, I should have taken a little longer to come up with a better example of the point.
