Finkelstein,
Yes, somewhat in agreement. Funnily enough, I remember arguing against evolution when I was 12 years old in a science class. It was Adam and Eve.
On another note, but still loosely affiliated with evolution and man, do you think this theory would satisfy creationists?
There were already humans living on Earth before Adam was created. Where Genesis says, "Let us make man in our image", it wasn't talking about God(s) creating man from scratch but improving an existing human couple by tinkering with their DNA.
It would give a satisfactory answer as to where Cain got his wife from and why he wanted to build a city for more than two people.
