Swiftly in evolutionary terms is still hundreds of years. So you are contradicting yourself again!!!! First you say that common descent is assumed based on looking similar. Wrong. Then you say old and new world vultures look the same because they made similar adaptations to similar environments. Then you contradict yourself and say they were always vultures and would not change. And now you contradict yourself AGAIN and say it had to happen quickly!
Wow are you ever ignorant and confused.
You're the one who is ignorant of your own Darwinist beliefs not me. The only reason you believe in Darwinism is because you are too stupid to understand it. If you understood it, you would see how darwinists are the ones who have contradicted themselves. They said that evolution had to happen very slowly, then they said it had to happen quickly. They said every animal was descended from one common ancestor, and now they shrug and say, well maybe all animals are not related after all.
You need to get out of the pathetic Darwinist internet chatrooms where you "learned science," and go to college like I did. Then you won't be so ignorant.
