Ancient peoples in South America had both Denisovan and Neanderthal DNA — and we have no clue how it got there

Ancient peoples seem to have mingled much more than thought possible.

Archeologists in Brazil are hard at work to uncover the genetic ancestry of some of South America’s earliest humans.

While the genetic contribution of Neanderthals to the modern human gene pool is well known, these ancient hominids are generally associated with Europe, especially Northern Europe. Denisovans, meanwhile, are generally associated with populations in Asia.

You can imagine, then, the surprise of archeologists working on two archaeological sites in Brazil when they discovered the presence of Neanderthal and Denisovan DNA in ancient South Americans.

Locally-produced
The findings are based on human remains recovered from archeological sites in Brazil, Panama, and Uruguay. Initially, the researchers working at these sites were aiming to map out the patterns of ancient migrations throughout the South American continent. This confirmed that migrations occurred from north-to-south along the continent, but also found evidence of migrations in the opposite direction along the Atlantic coast. But the genetic sequencing of these remains provided them with an unexpected surprise.

1. Those Neanderthals and Denisovans must have taken a LONG walk... nt

2. Aliens.....

It's obvious.

3. Both of which were picked up

(as I'm sure the archeologists will be quick to affirm) - long before any of these populations arrived in the Americas.

(unless we are totally turning history on its head. archeology is certainly in flux, but ... )

4. Interesting thought!

5. Picked up before immigrating to the Americas?

Would depend on the timing. We know Neanderthals were in Europe, and Denisovans in Asia, and we know that First People immigrated from Asia.

6. Very possible people traveled along the edge of the ice sheet across the northern Atlantic...

And I wouldn't discount the possibility of people getting across from Africa to Brazil. Get caught in a storm and who knows.

"Primitive people" were more mobile than we tend to think.

7. We consistently underestimate Paleolithic humans n/t

8. Indeed! Easier to blame it on "Ancient Aliens"...
