On Cultural and Reproductive Success: Kipsigis Evidence

Studies testing the evolutionary biological prediction that striving for cultural goals is a proximate means of attaining high reproductive success are reviewed, and some of their problems are examined. Recent data from the Kipsigis of Kenya provide robust demonstration that wealth enhances a man's reproductive success. The evolutionary significance of correlations between cultural and reproductive success, and the additional problem of interpreting studies conducted in the rapidly changing environments of modern man, are discussed.
