The pattern of evolutionary phylogeny has been highly reticulate mainly on account of hybridization (crossing between individuals belonging to populations which have different adaptive norms) followed by stabilization and perpetuation of some of the hybrid derivatives. The significance of hybridization in obtaining a picture of evolutionary relationships is discussed. First the evolutionary advantages that might result from hybridization are considered, second the drawbacks; finally the ways and degrees to which such drawbacks may be overcome are discussed.
