As with most of the things that Ken Ham says about evolution, it reflects absolutely no knowledge of the subject and includes invective and nonsense. As Mehta points out:
The entire point of science is to take what we know, try something new, find out new information, and expand our base of knowledge. The evidence for evolution springs from that process. You don’t need to regurgitate it. You don’t need to point to a science textbook. You can test it for yourself.This is something Ken Ham will never understand.
P.S. This is one of the reasons I don't use Twitter.
