Women marry men who look like dad...
Women tend to choose husbands who look like their fathers - even if they are adopted, reveals a new study.
The research shows that women use their dads as a template for picking a mate by a process called "sexual imprinting", says Tamas Bereczkei at the University of Pécs in Hungary and colleagues.
Husbands and wives have long been suggested to look alike and this is known to occur in many animal species. Couples that look like each other are also more likely to share common genes, and having a degree of similarity is believed to beneficial.
This might explain the study's findings, suggests Glenn Weisfeld, one of the research team and a human ethologist at Wayne State University, Detroit, US "There seems to be an advantage for animals to select a mate somewhat similar to themselves genetically," he told New Scientist.
"One good possibility is that there are some fortuitous genetic combinations which are retained in the offspring if both parents are similar," he says. "In humans there is evidence to show a lower rate of miscarriage."
However, he points out that there is a balance between the benefits of marrying someone genetically close and the harmful effects of inbreeding. "There seems to be an ideal balance, maybe around the first or second cousin point."
