Extract

Any reasonable generalisation on possibly fundamental rules of specific and generic differentiation would appear to be worth consideration. Defining our main terms briefly, we may here state that the genera and species of quantitative evolution are the genera and species recognised as such by responsible systematists who have considered entire groups in detail: the relatively few “critical” genera do not yield comparable data.
