And what's interesting is over time, we're likely to discover other places as we have more archeological digs and we find more fossil evidence of ancient agriculture and ancient peoples. And even the timeframe where we believe this happened, the 10,000, 12,000, 15,000 years ago, that's likely to maybe move back a little bit as we discover older and older evidence. So I'll leave you there, but the big takeaway is most of human history, we were not only making rough stones for our weapons and our tools, but we were chasing animals wherever we could find them. We didn't have predictable food sources. We were gathering fruits and grains and insects wherever we could to support our families. And there was a limit on how many humans could be around. But shortly after the end of the Ice Age, it all changed.
