    The evolution of sexual reproduction is an adaptive feature which is common to almost all multi-cellular organisms and also some single-cellular organisms with many being incapable of reproducing asexually. Prior to the advent of sexual reproduction , the adaptation process whereby genes would change from one generation to the next genetic mutation happened very slowly and randomly. Sex evolved as an extremely efficient mechanism for producing variation, and this had the major advantage of enabling organisms to adapt to changing environments. Sex did, however, come with a cost. In reproducing asexually, no time nor energy needs to be expended in choosing a mate.
