Link between altruism & suicidal tendencies?

Postby andthistoomustpass » Mon Oct 02, 2017 10:38 pm

Humans display altruistic behaviour, sometimes putting the good of the extended family (the tribe) before their own or putting themselves out or at risk to help a stranger. There is certainly a powerful cultural component at work here, I wonder if there is a genetic predisposition for our brains to work this way too. It would give a powerful advantage to the tribe who worked together when the chips are down and make it more likely that their culture and perhaps genes would propagate and so this behaviour would spread.
