Evolutionary psychology is a psychology informed by evolutionary biology of Homo sapiens. Evolutionary psychology postulates that the human brain, thus human psychological mechanisms have been shaped by natural selection in the specific ecological niche in order to cope with various problems that our ancestors met. Those mechanisms must be the sets of adaptive information-processing, and decision-making algorithms. In order to find out those algorithms, we should have a detailed knowledge about the course of Homo sapiens evolution and its ecological niche as well as a detailed knowledge about the workings of modern human minds. Some examples of previous researches and the future prospects of this decipline are summarised.
