Agreed, Jack. Science always changes with new relevant information. But right now,
Darwin is the man. And it looks as though DNA, RNA, and verifiable experiments back him up.

I think we can agree that it's always a good sign when scientists challenge orthodoxy.
There is no 100% in science as you have pointed out. This is only the province of religion which allows for no differences. Here "faith" becomes the 100% assurance. And this often trumps any scientific information.
