University of Bielefeld Researchers at Bielefeld University and the Technische Universität Braunschweig are the first to confirm the benefit of multiple paternities for a vertebrate under completely natural conditions. Together with their team, Dr. Barbara Caspers and Dr. Sebastian Steinfartz have shown that female fire salamanders mate with several males under natural conditions (so-called polyandry). This grants them fitness-relevant benefits by increasing their number of offspring. The...

In cultures that permit men to take multiple wives, the intra-sexual competition that occurs causes greater levels of crime, violence, poverty and gender inequality than in societies that institutionalize and practice monogamous marriage. That is a key finding of a new University of British Columbia-led study that explores the global rise of monogamous marriage as a dominant cultural institution. The study suggests that institutionalized monogamous marriage is rapidly replacing polygamy...

A social psychologist in the Netherlands says wealthy women tend to have more sons than their poorer counterparts. Dr. Thomas Pollet of Groningen University said data on 95,000 Rwandan mothers suggests low-ranking wives in polygynous marriages have more daughters than sons, Britain's Daily Telegraph said Wednesday. Our findings show that low-ranking wives, of third order or lower, have lower fertility than other women, suggesting that they are in poorer condition, Pollet said. These...

New research suggests that men from polygamous cultures outlive those from monogamous ones. Virpi Lummaa, an ecologist at the University of Sheffield, suggested that after accounting for socioeconomic differences, men aged over 60 from 140 countries that practice polygamy to varying degrees lived on average 12% longer than men from 49 mostly monogamous nations. The research looks to solve the long-standing puzzle of life expectancy in human biology. A phenomenon called the grandmother effect...

News of politicians' extramarital affairs seems to be in no short supply lately, but if humans were cut from exactly the same cloth as other mammals, a faithful spouse would be an unusual phenomenon. Only 3 percent to 5 percent of the roughly 5,000 species of mammals (including humans) are known to form lifelong, monogamous bonds, with the loyal superstars including beavers, wolves and some bats. Social monogamy is a term referring to creatures that pair up to mate and raise offspring but...

BANGUI (Reuters) - Central African Republic has ordered radio and television stations to stop broadcasting songs which encourage men to dump their wives, saying such music is a hindrance to the country's development.

"It's out of the question that...

The Financial Times quoted Employment Minister Gerard Larcher as saying...
