Gah. Classical evolution is over. To clarify: Evolution is real, but it is also glacially slow. Social changes are orders of magnitude faster, and technology faster still.
The odds of selective effects causing any changes whatsoever to human nature before someone rewrites our genome like it is a manuscript in dire need of editing are zero. The time scales are wrong. As far as evolution is concerned, if it takes us 300 years to master genetic engineering, and another 500 before the laws against it stop being enforced, then that is a bullet Darwin cannot dodge. And after that point, evolution is no longer blind.
