Abstract

Abstract: The dichotomy between 'typological thinking' and 'population thinking' features in a range of debates in contemporary and historical biology. The origins of this dichotomy are often traced to Ernst Mayr, who is said to have coined it in the 1950s as a rhetorical device that could be used to shield the Modern Synthesis from attacks by the opponents of population biology. In this two-part essay, I argue that the origins of the typology/population dichotomy are considerably more complicated and more interesting than is commonly thought. In the first part, I argued that Mayr's dichotomy was based on two distinct type/population contrasts that had been articulated much earlier by George Gaylord Simpson and Theodosius Dobzhansky. Their distinctions made eminent sense in their own, isolated contexts. In this second part, I will show how Mayr conflated these type/population distinctions and blended in some of his own, unrelated concerns with 'types' of a rather different sort. Although Mayr told his early critics that he was merely making "a temporary oversimplification, " he ended up burdening the history and philosophy of biology with a troubled dichotomy. Highlights: The origins of the typology/population dichotomy are traced. This dichotomy did not originate with Ernst Mayr, as is commonly thought. Early type/population distinctions due to Simpson and Dobzhansky are explicated. It is argued that Mayr confounded these individually meaningful distinctions. The resulting account is situated in the broader Modern Synthesis historiography.
