Researchers found that men are drawn to feminine looks - large eyes, pillow lips and a soft jaw - to a greater extent in countries that are the healthiest.
The reason for this difference is not clear, however scientists believe that evolution may drive these attractions, at least subconsciously, 'Live Science' reported.
According to Urszula Marcinkowska, a doctoral candidate at the University of Turku in Finland, men in harsh conditions may have a better chance of fathering children who survive if they mate with a woman who can hold on to resources.
Feminine women are also perceived to have less potential at acquiring resources, Marcinkowska said.
