5. For instance, he fails to notice the drastic difference between the domestication of animals and that of plants. Hybridization has played a very subordinate role in animals, but has been involved in the origin of many of the most important crop plants. More generally, hybridization is frequent in the plant kingdom and is not only responsible for all allopolyploids, but also for much other reticulate evolution. Among animals hybridization above the subspecies level is rare and in most taxa negligible.
