Lethal and nonlethal suicidal behaviors are major global public health problems. Much suicidal behavior (SB) occurs after the suicide victim committed a murder or other serious transgression. The present study tested a novel evolutionary model termed the Costly Apology Model (CAM) against the ethnographic record. The bargaining model (BRM) sees nonlethal suicidal behavior as an evolved costly signal of need in the wake of adversity. Relying on this same theoretical framework, the CAM posits…

Combat stress in a small-scale society suggests divergent evolutionary roots for posttraumatic stress disorder symptoms
It is found that symptoms that may have evolved to protect against danger, like flashbacks and startle response, were high in the Turkana and best predicted by combat exposure, however, symptoms that are similar to depression were lower in the Turks compared to American service members and were better predicted by moral violations.

Human suicide: a biological perspective
Four heuristic models are presented here to account for suicide in an evolutionary and sociobiological framework, suggesting that suicide should be tolerated by evolution when it has no effect on the gene pool.

Results indicate that when the harm-doers apologized, as opposed to when they did not, the victim-subjects refrained from severe aggression against them.
