WASHINGTON —
Scientists using sophisticated techniques to determine the age of bone fragments, teeth and artifacts unearthed in a Siberian cave have provided new insight into a mysterious extinct human species that may have been more advanced than previously known.

Research published Wednesday shed light on the species called Denisovans, known only from scrappy remains from Denisova Cave in the foothills of the Altai Mountains in Russia.

While still enigmatic, they left a genetic mark on our species, Homo sapiens, particularly among indigenous populations in Papua New Guinea and Australia that retain a small but significant percentage of Denisovan DNA, evidence of past interbreeding between the species.

Fossils and DNA traces demonstrated Denisovans were present in the cave from at least 200,000 to 50,000 years ago, and Neanderthals, a closely related extinct human species, were present there between 200,000 and 80,000 years ago, the new research found. Stone tools indicated one or both species may have occupied the cave starting 300,000 years ago.

1. So, 300,000 years ago?

Judi Lynn, I have read your posts again and a again, and I have watched documentaries about first man in the new world, and I have articles about it.

When do you conclude that man entered into America? I figure 40,000.

2. Searching, I found this

No idea of the veracity of this site or its content but I found more on the Denosivans and North American migration.

4. Wildly speculative

Existing figure is about 25,000 years ago. Not Denosovans.
