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?
How will the environment in the future be different from what it is currently? In what ways are the current anatomy and physiology of humans, squirrels, etc. insufficient to deal with these future environmental changes? If there are no environmental changes that a species can't deal with, then there's no selection pressure and therefore no major changes to a species. If there is a selection pressure, then the nature of that pressure must be known in order to determine the result of evolution of that species.
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.
Depends on the environmental pressures in the future. Also, humans are likely to engage in genetic engineering on our own species in the future to adapt humans to low-gravity environments and the like. We'll be responsible for our own evolution in the future, most likely.
