The first evidence we have of the development of agriculture in the Americas is about seven to eight or 9,000 years ago. So once again, it coincides with when agriculture, we believe, started to emerge in other parts of the world. And the more archeological evidence we find, we'll probably find dates that go even further back than that. In fact, I've seen some that go eight, 9,000 years ago. Now one misconception, significant misconception, about the Americas is that when the Europeans colonized, remember Columbus sailing in 1492 looking for the East Indies, and then he bumps into this, he actually doesn't bump into the whole continent, he bumps into an island that's close to the continent. But with that, you start having the beginning of the European colonization of the Americas, roughly the last 500 years. And one misconception that folks often have is, well, it was maybe sparsely populated, mainly by hunter-gatherer nomadic people, and nothing could be further from the truth.
