What are your thoughts on this?

Modern Homo sapiens is still evolving. Despite the long-held view that natural selection has ceased to affect humans because almost everybody now lives long enough to have children, a new study of a contemporary Massachusetts population offers evidence of evolution still in action.

A team of scientists led by Yale University evolutionary biologist Stephen Stearns suggests that if the natural selection of fitter traits is no longer driven by survival, perhaps it owes to differences in women's fertility. "Variations in reproductive success still exist among humans, and therefore some traits related to fertility continue to be shaped by natural selection," Stearns says. That is, women who have more children are more likely to pass on certain traits to their progeny.

Interesting, but such trends may accelerate or even reverse, quote, "Despite evidence that human evolution still functions, biologists concede that it's anyone's guess where it will take us from here". It's informed speculation and I'm always a little wary of "sophisticated statistical analysis that controlled for any social or cultural factors that could impact childbearing.." It depends on the 'controls'.

Indeed. I personally find the subject interesting and there are several good ideas going around about it.

Perhaps we can get an upgrade on this eye and lose the wisdom teeth and appendix?
