The intellectual discipline — distilled from Mayr's seven decades of practice — of naming accurately before building, insisting that description precede prescription and that what is in the river be identified before the dam is placed.
The taxonomist does not build dams. The taxonomist names what is in the river — distinguishes the species that look alike but are fundamentally different, identifies the populations that are diverging, warns when the isolation is deepening. The taxonomist's contribution is not action but accuracy: the insistence that before you build, you must know what you are building for, what you are building in, and what you are building with. This posture is what the Mayr simulation offers as the corrective to the AI moment — not a rejection of Segal's beaver metaphor but a complement to it. The beaver must still build. But the dam is placed well only if the builder first understands what is in the river, and the understanding requires the patience and precision of a practice that has spent a century watching systems evolve.
