It’s short and sums some things up very well. I’ve read dozens of books about the theory of evolution. It just doesn’t stand up to scientific standards. For leftists, it MUST be true because it is the only method, other than panspermia, that allows for a godless universe. So, even though it doesn’t stand up to scientific standards, they can not quit it because its would lead people to believe in God. And they can’t have that.
