What is the CDH13 gene psychology?

A further analysis found that two genes in particular, ‘cadherin 13’ (CDH13) – a gene involved in neural connectivity and ‘monoamine oxidase A’ (MAOA), a controller in dopamine levels in the brain, were associated with criminal behaviour.

Who has the MAOA gene?

The MAOA allele occurs in apes and Old World monkeys as well as in humans, leading to speculation that the allele arose 25 million years ago in the common ancestor of these primates and was subsequently favored by natural selection.

Not unsurprisingly, no one really knows the answer to this question. The most likely answer, though, is that the majority of the most prolific and dangerous serial killers were genetically disposed to behave anti-socially and furthermore grew up in an environment that cultivated a disregard for the lives of others.
