it is only when assisted by some form of segregation–which determines exclusive breeding of like with like–that heredity can effect arborescent or polytypic, as distinguished from catenated or monotypic, evolution.Romanes, G.J.

Natural Selection without isolation effects monotypic evolution, and only by the aid of isolating factors of some kind results in polytypic evolution.Leavitt, R.G. (1907). The geographic distribution of closely related species. Amer. Nat. 41, 207-240: 211.
