Funny
Very entertaining cartoon. I have taken a look at a bunch of reviews and I'd like to address a few things.
1) The guy who said something about species not being a hard thing, there is no 100% chicken or 99.9999 etc. % chicken, is right. Evolution happens very slowly, and it's impossible to state when it's a chicken or not a chicken. You can only look at focils and say "well that's DEFINATELY not a chicken".
2) There was a guy who said that this cartoon doesn't answer the question, just diverts it. Now which came first, the chicken-like creature, or the egg? And the answer is the egg... again. Another bird like creature hatched the egg, making the chicken-like creature. And where did this bird come from? Another bird. And where did that oen come from? Another type of bird. Keep going far back enough and eventually you get to dinosaurs. Bird evolved from dinosaurs.
So which came first the dinosaur or the egg? THe egg... it just keeps going back until the dinosaurs go back to the ocean, the ocean creatures get smaller and smaller, and eventually, you get a creature who mutated in some strange way to allow it's baby to develope outside it's own body in an egg. So eventually, a creature does come before the egg.
3) Someone mentioned that they don't understand how humans came from monkies. That's because humans didn't come from monkies. It's a misconception. Humans were never monkies. Ever. We were never gorillas, we were never apes. We just had a common ancestor. At one point, before there were humans or monkies, there was one species who gave birth to several (put simply, this happened over millions of years).
As for those who are religious and do not believe in evolution... I really dont' understand what there you don't believe in. Isn't it possible that God set up evolution? Perhaps God started the whole chain of events, and made sure it led to humans. Perhaps Adam and Eve were the first humans created (at least, by whatever standard God uses for humans).
Religion and science can merge very easily if you change "God did it" to "God set it up."
Anyway, with that said and done, I very much enjoyed your movie.
