What species will human kind become? Evolution works both ways, don't just look to the past, look to the future. What will the squirrel become? What will the bald eagle become?

What I don't understand is, after the dinosaurs were wiped out, why didn't evolution make some more of them. Or is that in the works and we just have not waited long enough. Or, did evolution 'decide' to make some different stuff this time around.

Yeah right! And if life began in the primordial soup billions of years ago has it happened again since? was this just a one time thing?

From what? Evolution only works with what's available. The dinosaurs were gone, so no dinosaurs were available to take their places. Birds and mammals vied for the new niches, with the birds gaining temporary ascendency before the mammals displaced them in most terrestrial ecological niches.

The only way for more dinosaurs to come about would have been for other surviving reptiles, such as crocodiles, to evolve in that direction or for birds to regain their dino features. There was no environmental pressure pushing reptiles and birds back into the dinosaur direction.

Furthermore, the empty niches left by the extinct dinos were quickly filled by various other types of animal, such as mammals.
