An article from the BBC covers one man’s theory about a bifurcation in the human race. He presumes that over long periods of time, sexual selection combined with dependence on technology will lead to beautiful, athletic men and women on one end of the spectrum, and hunched ugly little trolls of men (and women) on the other.
He neglects, in his up to 10,000 year outlook, one simple thing that is very likely to happen: we will gain the ability to manipulate and fix our bodies and even our genes. This very likely eventuality, should it come to pass, will nullify his whole idea. It is already coming to pass.
