The reason for the evolution of sex, and the reason(s) it has survived to the present, are still matters of debate.Life has evolved from simple stages to more complex ones, and so have the reproduction mechanisms.Initially the reproduction was a replicating process that consists in producing new individuals that contain the same genetic information as the original or parent individual.Multiplicity of gamete types within a species would still be considered a form of sexual reproduction.However, no third gamete type is known in multicellular plants or animals.
