Any explanation of human behavior that fails to take into consideration our evolutionary history is an explanation that can, at best, only answer part of the question. The following work attempts to illuminate a complex and often
misunderstood behavior: suicide. In a letter to Robert Hooke, Sir Isaac Newton remarked, “if I have seen further, it is by standing on [the] shoulders of giants” (Newton, 1675). Science builds upon the findings of previous researchers
and theorists, and the proposed model is no different. A number of evolutionary explanations for suicide have informed the proposed model. In this section I will touch upon this work and briefly review the core proposals
of each.
