As formulated by one contributor to thisvolume, however, the evolutionary increase in neocortex seen in primates has induced a signi?cant emancipation of - havior from hormonal determinants, and in parallel, an increasing role for intelligent socialstrategies(Keverne 2008).

Olfactory structures exhibit the same number of receptor genes, but a large number are transformed into non-coding pseudogenes.
