A LONG JOURNEY FROM AFRICA

Recent technical developments are making it possible for us to measure and understand our biological differences: we have come to understand that humans have the lowest degree of variability among primates, as can be expected in a species grown quickly through intense migratory exchanges. By comparing fossil archaeological and genetic data we are now able to retrace the main migratory events which led us from Africa to spread over 5 continents, in possibly less than one hundred thousand years. Such studies undermine the idea of separate biological races in our species, even at a time when the notion is returning in the political and social spheres.
