Until there was something that could be set against it—technology, art, consciousness—there was only “nature,” and so no real use for the category. It’s also probably true that by the time “nature” was invented, culture was already enmeshed in it. Twenty thousand years ago, wolves were domesticated. The result was a new species (or, by some accounts, subspecies) as well as two new categories: the “tame” and the “wild.” With the domestication of wheat, around ten thousand years ago, the plant world split. Some plants became “crops” and others “weeds.”
