The Selfish Gene Another criticism of the book is its treatment of morality, and more particularly altruism, as existing only as a form of selfishness: The philosopher Mary Midgley has suggested this position is a variant of Hobbes' explanation of altruism as enlightened self-interest, and that Dawkins goes a step further to suggest that our genetic programming can be overcome by what amounts to an extreme version of free will. Part of Mary Midgley's concern is that Richard Dawkins' account of "The Selfish Gene" serves as a moral and ideological justification for selfishness to be adopted by modern human societies as simply following
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
