Does Race Exist?

According to geneticist and anthropologist Spencer Wells:

"It's worth getting the message out, that we are related to one another, that we are much more closely related genetically than people may suspect from glancing around and looking at these surface features that distinguish us; so that's an important social message," Wells says. "Race, in terms of deep-seated biological differences, doesn't exist scientifically. We are 99.9 per cent identical roughly, at the genetic level."
