Literature, music, mathematics, art, are constituents of culture and each of them has its separate history. But each of them can also be seen as a manifestation of a human biological drive, a drive towards exploration, experimentation, the analysis of human perception. Culture is not something separate from human evolution but a part of a continuing human evolution, indeed the main form which human evolution has taken over the last few thousand years. It is a familiar idea, but perhaps a wrong one, that human evolution, as a Darwinian process, has ceased and been replaced by something quite new, a more Lamarckian process involving the inheritance of acquired characteristics, more specifically of the changing forms of human culture.But human culture can be seen as an aspect of human behaviour - and changes in behaviour in relation to changes in the environment are a central part of the Darwinian process of evolution for all creatures.
