there is evidence that west Africans specifically have a large contribution to their genetics from unknown hominid(s) species.

which may explain the unusually high frequency of genes associated with violence and criminality in west african populations and their descendants .

Melanin in vertebrates contributes to aggressive behavior because the pigment is important in neural development signaling


(Seriously look it up, mutations that disrupt it like the spider pattern in ball pythons have neural developmental disorders)
