The evolutionary advantage of psychological phenomena can be gleaned by comparing them with physical traits that have proven adaptive in other organisms. The present article provides a novel evolutionary explanation of suicide in humans by comparing it with aposematism in insects. Aposematic insects are brightly colored, making them conspicuous to predators. However, such insects are equipped with toxins that cause a noxious reaction when eaten. Thus, the death of a few insects conditions… 
Choosing Death Over Survival: A Need to Identify Evolutionary Mechanisms Underlying Human Suicide
TLDR
It is speculated that explorations of probable proximate explanations of suicide which stresses the need to diffuse attention paid to fitness consequences of the act alone are needed in order to build a robust and comprehensive evolutionary theory of human suicide.

Human suicide: a biological perspective
TLDR
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.

TLDR
Evidence on suicidal behavior among animals is analyzed to discover analogies with human suicidal behavior, and sparse evidence supports some resemblance between the self-endangering behavior observed in the animal kingdom, particularly in animals held in captivity or put under pressure by environmental challenges, and suicidalbehavior among humans.
Selfish and Spiteful Behaviour in an Evolutionary Model
TLDR
It seems to be a neglected question whether the harm delivered to an adversary is always merely an unfortunate consequence of adaptations for survival, and whether such harm ever be adaptive in itself.
When Saying “Sorry” Isn’t Enough: Is Some Suicidal Behavior a Costly Signal of Apology?
TLDR
Results provided mixed support for the hypothesis that some instances of suicidal behavior function to send a costly signal of apology to those harmed by a transgression, as well as supporting the Costly Apology Model.
Gestures of Despair and Hope: A View on Deliberate Self-harm From Economics and Evolutionary Biology
A long-standing theoretical tradition in clinical psychology and psychiatry sees deliberate self-harm (DSH), such as wrist-cutting, as “functional”—a means to avoid painful emotions, for example, or

Altruism and Related Phenomena, Mainly in Social Insects
TLDR
With better knowledge of heredity and with more facts regarding the social insects to draw upon, Weismann recognized the possible conflict between intergroup and intragroup selection in the evolution of worker attributes.

TLDR
It is concluded that the belief that kin selection is necessary for the evolution of aposematic coloration depends on the untested assumptioin that distasteful animals are killed during experimental tasting by predators.
