Evolutionary psychology explains the why of appreciation of beauty and neuroaesthetics explains the how of appreciating beauty. Evolutionary psychologists focus on two major reasons for why we admire the beauty of nature: sexual selection and natural selection/adaptation. Human physical beauty is based on sexual selection and what we find beautiful in nature is based on natural selection. Men find an hour-glass figure to be a fitness indicator that they find beautiful in women (a waist-to-hip ratio of 0.70 seems to be ideal); and a V-shaped body is a fitness indicator that women find beautiful in men. Women and men who have these qualities are perceived as likely to produce strong babies who will survive and later reproduce. The Savanna Hypothesis argues that it was adaptive to evolve to find attractive: (a) open spaces with short grass and groups of trees; (b) water nearby; (c) a panoramic view; (d) animals and birds present; and (e) greenery with flowers and fruits. Through natural and sexual selection, combined with the rise of human culture, we have learned to find beauty in myriad forms of art and craft. Through natural and sexual selection and natural cooperation, the human virtues developed and have taken on moral beauty.
