Is EP just SocioBiology warmed up?
I think there are three clear differences. Sociobiology believed all behaviours existed for the benefit of the gene. And therefore could be reduced to / explained by biological necessities.
EP in contrast ...
reintroduces interest in SexualSelection : therefore traits can exist not because they are utilitarian but attractive. (Suddenly there is no requirement to show that a behaviour increases utility to show that it is inate.)
introduces notion of memetics which is a theory of an autonomous cultural level that doesn't need to be reduced to the biological. Memes can exist because they are good at surviving, not because they help genes.
emphasizes difference between adapted and adaptive. Makes claims that behaviors are adapted to historical situation, not adaptive in current one.
