Throughout human evolution, individuals have subsisted in a variety of ways. These ranged from hunting and gathering, to forming nomadic tribes, to settling as a result of the agricultural revolution, and eventually to creating civilization once surplus resources were reliably established. It is undeniable that this progression resembles the evolution of a macro organism (such as a bee or ant colony) from single cells, through tissues, organs, and penultimately social organisms. In today’s world, most individuals (depending on location) are unlikely to possess the skills of hunting, gathering, or self-subsistence. We truly rely on one another in order to survive.
Using the evolutionary argument, the claim that this communal organization is a result of our genome is justified. So, it could be argued that human civilization is our genome’s most effective and successful method for ensuring its self-proliferation and survival.
Those who feel dissociated from society or are pathologically depressed for other reasons are more likely to commit suicide than others. Suicide is a valuable paradigm because it is so extreme; there is truly no evolutionary advantage for the individual’s genome. Obviously, suicide prevents this negative genomic impact from proliferating (e.g. genetically transmitted clinical depression from being passed to offspring). It also removes genes that may be deleterious to society (the human macro organism). Are suicides examples of detrimental genomic information culling itself from the gene pool? If individual humans are analogs for cells in the organism of humanity, is suicide programmed cell death? Does war follow the same logic?
