On the serious side.
the statement is true.
No longer are we driven by forces in nature.
We breed not with the strongest or the smartest or the fastest, there is no rhyme or reason to how we select a mate.
People with diseases like childhood diabetes are through the advent of technology able to keep the genetic pool filled with this flaw.
Asthma allergies and the rest are not even a consideration when breeding.
Evolution has hit a horrible point, Lord only knows if we can blow our selves up fast enough to insure that genetics dont kill us first.
