We are taught that all humans are human, and of the same species. But, surely, at some time not long ago, many human-like species did exist that were not necessarily the same species. Even that is controversial. So, if we look even further back we will find the point where our species diverged from the Chimpanzees.

What is the bar for identifying a new species of human should one emerge?

What would the broader social repercussions of this discovery be? Is anyone looking for them?
