Men living in harsh geographical and climatic conditions prefer women who have masculine features.

The responses were then analyzed and compared them with demographic and social characteristics of each country and found that men from countries such as Nepal, Columbia and Nigeria preferred women with masculine features while those from countries such as Japan, Australia and United States displayed preference towards women with feminine features.
Dan Kruger, an evolutionary psychologist from the University of Michigan, suggested that one of the reasons for disparity in preference could be due to harsh living conditions. “It seems like there’s a trade-off going on, where in the harsher environments, men are putting less preference on femininity. You could see how these preferences may or may not shift to see how deep-seated they are”, he said.
