As women become more financially independent, they seek older, more attractive male partners, according to a new study.
Previous work has found that women place greater emphasis on whether a man can provide for them when they are choosing a new partner.
The latest study, conducted by University of Abertay Dundee researchers, has revealed that as women earn more money their tastes actually change.
Greater financial independence gives women greater confidence in choosing their partner, and instinctive preferences for material stability and security become less important, the study found.
"We'd assumed that as women earn more, their partner preferences would actually become more like those of men, with a tendency towards preferring younger, more attractive partners rather than those who can provide and care for children," the Scotsman quoted lead researcher Fhionna Moore, of the University of Abertay Dundee, as saying.
"However, the preferred age difference did not change as we had expected," said Moore.
The findings were published in the journal Evolutionary Psychology.
