Will we recognize ourselves in that future? Or will we be so different from evolutionary drivers that we might have either more biological talent or perhaps even less? Usually you get new species when they split, when they speciate, and that's not going to happen with humans. But if we set up colonies on Mars, for example, then it would be not unexpected that they might become a separate species which could no longer interbreed with us.
Our evolutionary journey concludes with Neil deGrasse Tyson, Richard Dawkins, Bill Nye, Eugene Mirman, Jim Gaffigan and Maeve Higgins, recorded live at the Beacon Theatre in NYC.
