Summary Introduction

To test: The given hypothesis for evolution of human traits arisen by sexual selection.

Concept introduction: Sexual selection is the process or a form of natural selection where a member of one sex chooses its mate from the opposite sex (intersexual selection) and to mate with the opposite sex, it should compete with the member of the same sex (intrasexual selection). Sexual selection leads to the evolution of some traits that help in sexual attractiveness among the partners.

Some human traits may have arisen by sexual selection. Over thousands of years, women attracted to charming,  witty men perhaps prompted the development of human intellect beyond what was necessary for mere survival.  Men attracted to women with juvenile features may have shifted the species as a whole to be less hairy and softer  featured than any of our simian relatives. Can you think of a way to test this hypothesis?
