Does True Altruism Exist In Nature?

Does true altruism exist in nature?
Within nature Darwin has proposed the notion of natural selection as the driving force of evolution. Individuals acquiring traits solely designed for their survival and reproductive fitness. Accordingly, animals act selfishly to survive and pass along their genes to future generations. Since then, controversy has circled around the idea of organisms acting out in a selfless manor decreasing their fitness for the success of another member’s fitness. Its puzzling to assume individuals will sacrifice themselves for the benefit of another member when Darwin’s assumptions were predominately associated with the survival of the fittest. Explanations to this issue have been observed amongst kin where family members will help the survival of its relatives in order to increase the success of the group; this is otherwise known as kin selection and is one explanation of altruism. Similarly,
Altruism is defined as a social behavior that decreases the fitness of the actor in turn increasing the fitness of the recipient. (West). While Darwin believed in natural selection he was also aware of many functional help services amongst animals. Therefore, Darwin presumed natural selection to favor socially interactive animals by enabling advantageous traits that indirectly benefit the species at the group level. According to Mr. Domondon’s review, Darwin presented a theoretical species where some monkeys will inherit a gene that permits alarm singling when predators are spotted, while others will not. Essentially the species that contain monkeys with this trait will sacrifice themselves, or engage in costly behavior causing a greater amount of its group members to survive and pass down the alarm-signaling gene. If such genes are generating a higher reproductive success then groups who do not possess the gene, then this altruistic trait will become inherited; fundamentally causing more altruistically modified
