“If efficient copying is adaptive, such that natural selection should favor greater and greater reliance on social as opposed to asocial learning, then the tournament also establishes that a number of characteristics strongly evocative of human culture will follow automatically.… — Kevin N Laland Copy Share
“If efficient copying is adaptive, such that natural selection should favor greater and greater reliance on social as opposed to asocial learning, then the tournament also establishes that a number of characteristics strongly evocative of human culture will follow automatically. With increasing copying inevitably comes greater behavioral diversity; the retention of cultural knowledge for long periods of time; conformity; and… — Kevin N Laland Copy Share
“Strategies that did well in competition with other strategies were not, however, those that maximized the returns to agents. Rather, we found a strong inverse relationship between the mean fitness of individuals in populations containing only one strategy, and that strategy's performance in the tournament. This finding illustrates the parasitic effect of strategies that rely heavily on OBSERVE. Strategies using… — Kevin N Laland Copy Share
“When changes in one genetic trait are the source of selection for changes in a second, the rate of response in the latter depends in parts on the rate of change in the former, which, as a rule, is not fast. In comparison, if a cultural practice modifies selection acting on human genetic variation, then the greater the proportion of… — Kevin N Laland Copy Share
