Amongst issues that evolutionary psychology (EP) undertake there is a problem of morality. Evolutionary psychologists not only consider evolution and nature of morality, but also discus the problems of normative ethics and metaethics. This paper is the critical analysis of the possible implications of evolutionary psychology for free will, responsibility and punishment. On the ground of EP I will argue (1) in favour of free will and moral responsibility (2) but against the traditional form of punishment by imprisonment in case of offenders which crimes are results of biologically determined dysfunction of brain. These conclusions are broadly consistent with the solutions adopted in many systems of criminal law.
