CONCEPT
Population Thinking
Mayr's formalization of Darwin's deepest conceptual revolution — the replacement of <em>typological</em> thinking with the recognition that <em>variation</em>, not average, is the fundamental biological reality.
Before Darwin, the dominant mode of biological thinking was typological. The species was conceived as a type — an ideal form, an essence — and individual organisms were understood as imperfect copies of that type. Variation between individuals was noise; the real thing was the type. Darwin's revolution inverted this: the variation is not noise, it is the signal. Without variation, there is no natural selection. Without selection, there is no adaptation. Mayr formalized this insight into the distinction between typological thinking and population thinking, arguing that it constituted the most important conceptual revolution in the history of biology. "Averages are merely statistical abstractions," he wrote. "Only the individuals of which the populations are composed have reality."
