[ Biology ] Open Question : A question about evolution, involving dinosaurs? Please answer seriously.?
I just watched a jurassic park movie marathon (I know it's full of inaccuracies lol, it bugs me all the time. But it was on tv, and I was bored :P)
So, they mentioned something I heard a few times outside the movies, and I got to thinking...
they say that they evolved into modern day birds, but I don't quite understand how or why that would be a positive mutation that would be passed on. Can anyone explain? I'm confused. I know the extinction theories and none of it really makes much sense to me still. I'm not saying I do or don't believe the theory fyi - I'm just asking the explanation on this. Please answer seriously. I'm curious.
