Unattractive women are more likely to chase attractive men in an effort to boost their children's genes, new research has suggested.
This goes against previously held opinions that attractive people are drawn to each other, instead implying that only one attractive partner is necessary.
It is thought that women pursue men who are handsome to give their children a greater chance of reproducing since they will be more attractive, the researchers from the Department of Anthropology at Poland's University have found.
Better looking women, meanwhile, do not need to find a handsome man with whom they can reproduce, since their own attractiveness genes will give their children the boost they need to succeed in the world of reproduction.
The researchers concluded: "It can be hypothesised that women with higher waist-to-hip ratio, i.e. less attractive ones, may more intensively 'hunt for genes' related to attractiveness to increase their offspring's chance to be more attractive and to have a greater chance of reproductive success."
