Genes are important for understanding our behavior. Incredibly important - after all, they code for every protein pertinent to brain function, endocrinology, etc.

Naturally, things are more complicated - those groovy, pro-social effects of oxytocin apply to how we interact with in-group members.

The less it is possible that something can be, the more it must be.

Almost always, genes are about potentials and vulnerabilities rather than about determinism.
