That's right. They are discussing it and hopefully they will do it next season!!

"My goal this year is to prove natural selection on the show. It's gonna take a while, it's gonna be very hard to make it fascinating on film in the context of our narrative structure, but I figure screw it. The sky's the limit. Let's do, Let's do natural selection. I'm sick of fifty percent of this country thinking creationism is reasonable. It's appalling. And I have the unique ability, maybe, to sell this idea to Discovery, and they'll, they might allow me to do it, and I'm gonna try as hard as I can."
The thing about doing a show on Natural Selection is that most creationists already accept it. I think it might be a good idea to create an evolutionary computer algorithm for the show to demonstrate that mutation and selection can and do produce complexity.It would also be a good idea to show that cerain things (homologous structures, vestigial organs, atavisms, etc.) are present when evolution from common ancestry is simulated, and that these things are present in the real world.
