What the hell are you talking about? If you are going to change the form of an animal, there has to be a change or mutation early in the formation of that animal while the body plan is being formed. And when that occurs, it is always fatal.
False assumption. Certainly there are some mutations that can be fatal...absolutely.
But how is it you don't notice obvious mutations in existing living animals?
If someone has a mutation that causes them not go grow lungs; that's fatal. If someone has a mutation that caused them to have 6 fingers...Not fatal.
we all know perfectly well there's nothing wrong with a 6 toed cat. they can do very well.
what we're into, seems like, is that for the part of the "chaos" that surrounds us, there's a theory to explain a piece of it. and that theory is called evolution. there's observations, studies, and extrapolations that have occurred that have allowed us to come with terms with what is happening to the natural environment and it's segments or components over a period of time. apparently the dinosaurs lost their ability to adapt for whatever reason. so, it was requiring a re-start.
dinasours couldn't get into space for whatever reason. maybe too slow & clumsy because they were cold-blooded.
they did provide solutions to a lot of other challenges though. locomotion, walking on their hind feet, eating meat, etc. etc.
maybe we haven't given them proper credit for their contribution to our past development that has led us to our current successes?
