Edward O. Wilson called humans eusocial apes, arguing for similarities to ants, and observing that early hominins cooperated to rear their children while other members of the same group hunted and foraged. [46] Wilson and others argued that through cooperation and teamwork, ants and humans form superorganisms.
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies. Sociality is a survival response to evolutionary pressures. [1] For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. [2]
For example, territorial choruses by male lions discourage intruders and are likely to benefit all contributors. [2] This process contrasts with intragroup competition where individuals work against each other for selfish reasons. Cooperation exists not only in humans but in other animals as well.
Cooperation is common in non-human animals. Besides cooperation with an immediate benefit for both actors, this behavior appears to occur mostly between relatives. Spending time and resources assisting a related individual may reduce an organism's chances of survival, but because relatives share genes, may increase the likelihood that the ...
The concept of "reciprocal altruism", as introduced by Trivers, suggests that altruism, defined as an act of helping another individual while incurring some cost for this act, could have evolved since it might be beneficial to incur this cost if there is a chance of being in a reverse situation where the individual who was helped before may perform an altruistic act towards the individual who ...
The co-operative behaviour of social insects like the honey bee can be explained by kin selection.. Kin selection is a process whereby natural selection favours a trait due to its positive effects on the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction. [1]
W. D. Hamilton [13] was among the first to propose an explanation for natural selection of altruistic behaviors among related individuals. According to his model, natural selection will favor altruistic behavior towards kin when the benefit (as a contributing factor to reproductive fitness) towards the recipient (scaled based upon Wright's coefficient of genetic relatedness between donor and ...
Human reciprocal altruism seems to be a huge magnetic field to interweave different disciplines closely. New exploration has been made by these disciplines at different levels from different points. Generally, the core of Human reciprocal altruism is located in the puzzle: How to overcome short-term self-interest and achieve cooperation.
