The Evolution of Cooperation on. When Richard Dawkins set out to "examine the biology of selfishness and altruism" in "The Selfish Gene", he reinterpreted the basis of evolution, and therefore of altruism. He was "not advocating a morality based on evolution", and even felt that "we "must" teach our children altruism, for we cannot expect it to be part of their biological nature." But John Maynard Smith was showing that behavior could be subject to evolution, Robert Trivers had shown that reciprocal altruism is strongly favored by natural selection to lead to complex systems of altruistic behavior (supporting Kropotkin's argument that cooperation is as
Evolution of the brain evolution once the divergence between chimpanzees and humans had already occurred. Each of the gene sequences went through specific changes that led to the evolution of humans from ancestral relatives. In order to determine these alterations, Lahn and his colleagues used DNA sequences from multiple primates then compared and contrasted the sequences with those of humans. Following this step, the researchers statistically analyzed the key differences between the primate and human DNA to come to the conclusion, that the differences were due to natural selection. The changes in DNA sequences of these genes accumulated to bring about a competitive advantage
