摘要
A central tenet of 演化ary 社會 science holds that behaviors, such as those associated with 社會 dominance, produce fitness effects that are subject to 文化 selection. However, evidence for such selection is inconclusive because it is based on short-term 統計 associations between behavior and fertility. Here, we show that the 演化ary effects of dominance at the 族群 level can be detected using noncoding regions of DNA. Highly variable polymorphisms on the nonrecombining portion of the Y chromosome can be used to trace lines of descent from a common male ancestor. Thus, it is possible to test for the persistence of differential fertility among patrilines. We examine haplotype distributions defined by 12 short tandem repeats in a sample of 1269 men from 41 Indonesian communities and test for departures fr
