From the always interesting................

 .....................................Kevin Kelly:

Our humanity is something we invented over the course of a million years. It’s our first and most important “tool”. In fact, we ourselves — humans — are the first wild creations we domesticated, before wheat, corn, dogs, cows and chickens. We’ve been modifying ourselves, and our genes, since day 1. It’s true that most of our behavior is primitive, unchanged, ancient, and no different than our animal cousins. But not all. And it is these different bits that make us human.
