In this hour, TED speakers explore our origins as a species — who we are, where we come from, where we're headed — and how we're connected to everything that came before us. In an updated interview, futurist Juan Enriquez says homo sapiens are becoming a new species, right before our eyes. Other guests from the original 2014 episode include geneticist Spencer Wells, historian David Christian, paleontologist Jack Horner, and anthropologist Louise Leakey.
