The last twenty years or so have seen a resurgence of interest in human evolution in many aspects. A distinction can be made between 'narrow' and 'broad' human evolution. The broad perspective is beginning to make its presence felt, for example, through the developments in evolutionary genetics, evolutionary psychology and behavioural ecology. Here, the limits of human evolution are explored, using two approaches - first, finding where humans 'fit' the expectations of evolutionary principles; and second, applying evolutionary methods to particular human contexts, whilst looking for an evolutionary signal.
