I promoted the topic because it mentions the relatively recent phenomenon of decreasing fertility among young men.

Re: Evolution by Personal Selection

No. What he is saying is that humans, through our technology, are no longer subjet to the driving force of evolution, natural selection.
More accurately, those human populations with access to the necessary technology can render themselves immune to some forces of selection.
Interestingly, a recent genetic analysis of human populations indicated that Homo sapiens are evolving more rapidly today than in the past. If this finding holds up, one possibly valid implication is that our technologically altered environment is feeding back on our evolution.
