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.
