The Evolution of Culturally Transmitted Teaching Behavior

摘要: The replacement of Neanderthals by modern humans may possibly have been influenced the different cultural transmission mechanisms two hominins. Since teaching is widespread in human societies, but extremely rare animals, it played an important role evolution. In humans, how and whom to teach may, part, be transmitted culturally. Therefore, this paper, I develop a model teaching. show that even when costly, can evolve provided teachers transmit their traits more actively than non-teachers. Teaching likely cost social learning low relative individual learning, accurate, environment stable, effect extensive. Under certain conditions, states, existence non-existence population, are evolutionarily stable (bistable). When happens, sometimes maintained under unstable environments where cannot exist without Differences subsistence strategy group structure between affected evolution behaviors
