I am sorry cofty I didn't see I was hijacking the thread thank you for pointing out my wrong ways how I could I become better. And I suck at sarcasm as well.
#1 I agree that we don't have a good or accepted definition of Homo sapien. Maybe I am to ignorant on the subject but I don't see why we couldn't arrive at one. If we claim we are clearly humans(in the video he makes this claim) and that his resent ancestors are clearly humans what makes them so clearly humans. Couldn't that criteria be used to test the rest of the ancestors.
#2 Again I might just be ignorant but I don't see why evolution cannot be applied to individuals as well.
