Thanks. That's interesting. I didn't know about that at all and though I don't know dingos well, they're one of my favorite animals. Like coyotes, they just seem so intelligent and robust as animals. Very cool.
>>crossed the land bridge with early Native Americans
I was just listening to a podcast series on the people of America (in French, so I won't bother to link), but it seems that among scholars, the idea that all American Indians** crossed the land bridge 12,000 years ago is almost universally rejected. The evidence was always poor, but for a while a few influential scholars forced others to fit their evidence into that framework or be rejected. But for decades now, scholars have said that people came to the Americas much earlier than that.
Currently, they simply say that people arrived in the Americas sometime between 20,000 and 60,000 years ago, almost certainly in multiple waves and possibly by multiple modalities. Interesting debate.
**The local tribal councils have requested that, by preference, Indians be referred to by their tribal names when appropriate (i.e. when referring to one tribe), and by the collective "Indians" when referring to them as a group. Every time NPS posts something to Facebook using the terminology requested by the local tribal councils, there is a flurry of people calling them racist imperialists and demanding they use the "correct" term, "Native American," as specifically rejected by the local tribes because (as a tribal member explained to me), properly speaking, anyone born here is native to the Americas and, properly speaking, over a long enough timescale, everyone outside of East Africa is descended from immigrant stock.
