  For speciation you need some kind of separation, which does now sometimes happen within a generation (e.g. one social group refusing to date another social group), but is very unlikely to persist across many generations. Evolution by natural or sexual selection within a single species can still occur.

  haven't we as a species already denied natural selection long ago? No, how could we? We have influenced external pressures such as predators on our selection, at most.

  > For evolution you need physical separation. With our level of globalisation that's not going to work. Global empires are nature's way to shuffle some genes around and reduce inbreeding. Then individual nations start to exploit the empire for their selfish benefit, everything falls apart and nature runs an iteration of competitive evolution for a change. Rinse, repeat.
