CTD, the substance in question is called keratin, not collagen, so my bad. Keratin is a protein that makes up most of the material in the cells forming the beaks, feathers, hair, hooves, horns, nails, scales and skin of animals.

In other words, no matter how different the 'kind' of animal, no matter what its needs are, apparently the creationist god was so limited in his abilities that he had to use and reuse the same substance over and over, and over again. He couldn't even once come up with a new substance, better designed to suit the animal's lifestyle. That's why your tender skin and a lion's nasty claws, a horse's strong hooves and a bird's delicate feathers, a cow's horn and a husky dog's warm fur are all basically the same thing. I don't think you really addressed this in your response.



Failure there then, since the vast majority of creatures that have existed are now extinct.



So where in creationist theory is your evidence that it was one god and one god only who created everything? Apart from "it says so in the Bible"?



Interesting how you are separating all of these. Are you honestly saying that Darwin is the only one on the list who accepts evolution? Interesting. As far as I'm aware, I've made it pretty clear that I accept evolution to be the best explanation for what we see in fossils and how they are sorted in the geological column.

I think you're on about spontaneous generation again because you like to use this to paint scientists as idiots. People used to think the earth was flat, too, until science proved otherwise. People have held a lot of erroneous beliefs in the past until science proved otherwise, and this includes spontaneous generation. Case closed.

I'm still waiting to see you back up any of your claims with solid evidence.
