BEAUTY is in the brain of the beholder: it seems the brains of men and women respond differently to beautiful landscapes. This may stem from the varied evolutionary pressures on the two sexes in our hunter-gatherer ancestors.
A team led by of the University of the Balearic Islands in Palma, Majorca, Spain, asked males and females whether photographs of natural and urban landscapes were beautiful or not.
When they looked at a scene they deemed beautiful, both men and women had greater electrical activity in the parietal region, near the top of the brain. In women, this activation occurred in both halves of the brain, but in men it was restricted to the right hemisphere (Proceedings of the National Academy of Sciences, ).

This might reflect evolutionary differences, the team suggest. In early humans, they say, men were hunters who needed mental maps of distance and direction, while women gathered plants for food and oriented themselves using landmarks.
This fits with data that the left brain handles 鈥渃ategorical鈥� spatial relations, such as landmarks, while the right evaluates 鈥渃oordinate鈥� data, such as distance and direction. The team say that what we find beautiful may have evolved from what our ancestors looked for in a habitat.
