Here's another defrocked weatherman or whatever putting it at 70,000 years and claims race is not genetic.No one knows for how long the different races have been evolving independently, but it might be necessary to go back one million years or more to find an ancestor common to all races. Clearly, a great deal of divergence has taken place during that time.
Next they will claim that aliens landed in Africa 300,000 years ago and were the source of all mankind. Oh wait.....Our broad racial categories appear to be founded on genuine biological differences between people from different geographical regions. And these differences seem to define a set of natural human groups, the product of the last 70,000 years or so when modern humans emerged from Africa to colonize the other continents, acquiring distinct physical traits as they adapted to new environments.
You can be from Africa if you want Spike, I prefer to think I am from a galaxy far far away..LOLHumans contain ‘alien’ genes not passed on from our ancestors, researchers have discovered. Scientists have discovered parts of our DNA which are not traced back to any known human ancestor.
