That wasn't me, and I said "in the usual sense" specifically because the context was Will's (unusual) definition.
I differentiate between selection and genetic drift like usually done and the case of blue eyes would be an example of the latter. I think the difference is normally described as selection being a consistent non-random effect. Personally I'd describe it as an effect on the relative frequencies caused by the presence of the gene.

I apologize for confusing you with him.
Personally I'd describe it as an effect caused by the presence of the gene, which genetic drift isn't.
Okay, well I would still guess that natural selection is going at a good clip these days. For example it seems pretty likely that the gene for twinning is spreading pretty fast.
I was browsing my RSS feed, as one does, and came across a New York Times article, "A Village With the Numbers, Not the Image, of the Poorest Place", about the Satmar Hasidic Jews of Kiryas Joel (NY).
Their interest lies in their extraordinarily high birthrate & population growth, and their poverty - which are connected. From the article:
From Wikipedia:
Robin Hanson has argued that uploaded/emulated minds will establish a new Malthusian/Darwinian equilibrium in "IF UPLOADS COME FIRST: The crack of a future dawn" - an equilibrium in comparison to which our own economy will look like a delusive dreamtime of impossibly unfit and libertine behavior. The demographic transition will not last forever. But despite our own distaste for countless lives living at near-subsistence rather than our own extreme per-capita wealth (see the Repugnant Conclusion), those many lives will be happy ones (even amidst disaster).
So. Are the inhabitants of Kiryas Joel unhappy?
