I find it interesting for a few reasons:
1. Humans apparently get here within a few thousand years of the Pleistocene extinction. I'm curious about how that dynamic went down.
2. Did the Megalith cultures of the New World have contact with those of the Old, or some common source culture?
3. Politics. If the first New World humans were European, then none of the three remnant linguistic/genetic groups of Asiatic stock gets to claim "Native American" status any more than me, as a native Californian. Peaceful "Native Americans" in harmony with nature bs will be dealt another blow.
4. We can finally uncover the truth behind the Mysterious Dinosaurs of Acambaro.
