racial differences in early ability

A recent paper by Levitt and colleagues that generated some discussion is linked below. it shows that there is very little difference in measured abilities by race at 8-12 months but that differences begin to appear at age 2. They do make all the caveats, but in my view come down on the side of the argument that suggests that their results are a blow to genetric causation and are more suggestive of environmental causation. worth a read but i think it is very much an opening move in this debate rather than anything conclusive.
