  Title Why does culture increase human adaptability? Type Journal Article
  Year 1995 Publication Ethology and Sociobiology Abbreviated Journal Ethol. a. Sociob.  
  Volume 16 Issue 2 Pages 125-143  
  Keywords Social learning; Adaptation; Culture; Sociobiology  
  Abstract It is often argued that culture is adaptive because it allows people to acquire useful information without costly learning. In a recent paper Rogers (1989) analyzed a simple mathematical model that showed that this argument is wrong. Here we show that Rogers' result is robust. As long as the only benefit of social learning is that imitators avoid learning costs, social learning does not increase average fitness. However, we also show that social learning can be adaptive if it makes individual learning more accurate or less costly.
