The Santa Elena Peninsula, a dry thumb of land poking west into the sea off coastal Ecuador, reached much further out. Mangroves grew along its ancient shoreline, and in those mangroves, clams flourished. The people who ate those clams were already doing something extraordinary. They were planting seeds. By approximately 8000 BCE, the Las Vegas culture was domesticating squash, one of the earliest agricultural experiments anywhere in South America. They were still hunters, still gatherers, still fishers. But they were also becoming farmers, and they were doing it on a coastal desert where it almost never rained.
