And we have archeological evidence of humans in Southern Chile as early as 14,500 years ago, and as well in Florida as early as 14,500 years ago. So humans had migrated into and settled in the Americas many, many, many thousands of years ago. And like other places in the world, they followed similar development patterns. 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.
