Change within species via mutations and natural selections? Yes I believe I do understand...I also anticipated your tired "creos dont understand evolution" argument.
So why arent reptiles producing mutated offspring with hair and fur?
Thanks for clearly and directly proving my point.
Really? so change in populations via inherited traits, mutations and natural selections isnt what Evolution is about? Wow! Evolution Theory is constantly evolving.
You say the words and don't understand what they mean.
