Document Summary
A starting framework: there is a gene-culture co-evolution, which feeds into neural structure (anatomical differences between. Joseph he(cid:374)ri(cid:272)h sa(cid:455)s the se(cid:272)ret of our su(cid:272)(cid:272)ess is that: (cid:862)we"re a species addicted to culture(cid:863). We adapted cultural learning to take in information, which is the distinguishing feature between humans and other animals. If you check you blood sugar levels after drinking a litre of milk and they consistently go up. They clustered near milk fat: using old artifacts (clay bowls that held milk), he hoped their pores would conserve milk fats. If this mutation existed once dairy was introduced, the mutation may have persisted because it provided the selective advantage of consumption of a major food source. 1: milk was very beneficial because it was high in protein and fat. Genes underlying the cultural self: 5htt gene (serotonin transporter gene), found in people susceptible to mood and anxiety disorders.
