Race and language in the Darwinian tradition (and what Darwin’s language–species parallels have to do with it)

What should human languages be like if humans are the products of Darwinian evolution? Between Darwin’s day and our own, expectations about evolution’s imprint on language have changed dramatically. It is now a commonplace that, for good Darwinian reasons, no language is more highly evolved than any other. But Darwin, in The descent of man, defended the opposite view: different languages, like the peoples speaking them, are higher or lower in an evolutionarily generated scale. This paper charts some of the changes in the Darwinian tradition that transformed the notion of human linguistic equality from creationist heresy to evolutionist orthodoxy. Darwin’s position in particular is considered in detail, for there is disagreement about what it was, and about the bearing of a famous paragraph in the Descent comparing languages and species.
