Men ‘are no more promiscuous than women’

Washington, Apr 25 (ANI): The long standing belief that men are promiscuous and females are selective when choosing a mate is a myth, claims a new study.

The research, published by Cell Press in the April issue of the journal Trends in Ecology and Evolution, suggests that human mating strategies are not likely to conform to a single universal pattern and provides important insights that may impact future investigations of human mating behaviors.

In 1948, Angus J. Bateman’s performed some now famous studies in fruit flies that showed that males exhibit greater variance in mating success (the number of sexual partners) and in reproductive success (the number of offspring) when compared to females.

In addition, Bateman showed that there was a stronger relationship between reproductive success and mating success in males than females.
“The conventional view of promiscuous, undiscriminating males and coy, choosy females has also been applied to our own species,” says lead study author Dr. Gillian R. Brown from the School of Psychology at the University of St. Andrews.

“We sought to make a comprehensive review of sexual selection theory and examine data on mating behavior and reproductive success in current human populations in order to further our understanding of human sex roles,” the expert added.

To reach the conclusion, Brown and colleagues examined the general universal applicability of Bateman’s principles. To test one of Bateman’s assumptions, they collated data on the variance in male and female reproductive success in 18 human populations.

While male reproductive success varied more than female reproductive success overall, huge variability was found between populations; for instance, in monogamous societies, variances in male and female reproductive success were very similar.

The researchers also examined factors that might explain variations across human populations that are not in keeping with the prediction of universal sex roles.

“Recent advances in evolutionary theory suggest that factors such as sex-biased mortality, sex-ratio, population density and variation in mate quality, are likely to impact mating behavior in humans,” concludes Brown. (ANI)
