摘要: Cultural variation can affect the genetic evolution of a species if there are consistent cultural differences that contribute to fitness between groups individuals. In this study, measures reproductive success sperm whales from different clans used as proxies for fitness. We measure using population length distributions acoustic and photographic measurements visual observations presence calves. The results obtained generally methods; large significant in success. study strengthen case hitchhiking by indicating culture correlate with
