The research claim that individuals are generally attracted to the opposite sex with similar facial features to their own, but after a stressful experience, blokes" preferences change to include a wider variety of women
In the study, it is found that relaxed males rated women 14 percent less appealing if they looked very different from themselves compared with women who looked similar. But a group of stressed men found dissimilar women 9 percent more attractive.
Johanna Lass-Hennemann, said, "Men have a tendency to approach dissimilar mates and to rate these to be more pleasant when they are acutely stressed. But we are not sure how this might reflect in true mating decisions."
The scientist are of the view that stress might increase men's tendency to "outbreed", or reproduce with more genetically dissimilar women, with the obvious benefit that any children born from the relationship might be better equipped to cope with a stressful environment.
