Reciprocal Altruism Theory
{"Image DocumentName": "Reciprocal Altruism Theory", "Image ImageDescription": "Proposed by Trivers (1971). Natural Selection may create psychological mechanisms designed to deliver benefits even to non-relatives, provided that such actions lead to reciprocal beneficial actions in the future. This is not necessarily limited to the same species e.g. cleaner fish. If the benefit received is larger than the cost incurred, then individuals who engage in such behaviour will out-reproduce those who do not. E.g, in vampire bats, an individual will share food with a conspecific (whether related or not) if the other has shared food with that individual in the past.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
