This is granting too much priority to biology. It is not accurate to state that a biological substrate creates dispositions; rather, social relations and biological features are mutually determinative. For instance, brain development shapes and is shaped by social interactions in early childhood. I know that andie has made this very point in LBO posts in the past, but the phrasing above could be easily misconstrued as the claim that biology is the precedent.
A minor point, perhaps, but I take every opportunity to undermine the pernicious and misleading notion that there is some biological substrate modified by a sociocultural veneer.
