This next story would fit in either the evolution section or this DNA section. I'll post it here.

COLD TRUTH ‘Missing link’ in human evolution found after 30,000-year-old remains are dug up – rewriting history of first American settlers

Excerpts:
NEWLY discovered ancient teeth dating back 31,000 years are evidence of a new ethnic group in human history - and could change everything we know about the first American settlers.

Living in extreme arctic conditions in Siberia during the last Ice Age, the previously-undiscovered group is being hailed by scientists as a "missing link in evolution".

The ancient people have been named as 'Ancient North Siberians' and the new study suggests that they would have survived in harsh conditions by hunting woolly mammoths, woolly rhinoceroses and bison.

They were discovered thanks to DNA analysis of two ancient milk teeth, found buried deep at the Yana Rhinoceros Horn archaeological site in Russia.

Professor Eske Willerslev, who led the study, said: “The Yana site 31,000 years ago was an Arctic steppe - more rich in plant diversity than today and dominated by varies forbs and grasses, there were very few trees if any. The animal life was very different than today.

"It was more like what we know from the African savanna with mammoth, woolly rhino, horses, bison, wolves and lions. The Ancient North Siberians were hunting these particularly rhino and mammoth.”

The discovery was made as part of a wider study which also found 10,000 year-old human remains in another site in Siberia.

These 10,000 year-old remains are being labelled as the missing link in the story of Native American ancestral history.

DNA analysis revealed that a male skeleton found at the Kolyma site contained a mixture of Ancient North Siberian DNA and East Asian DNA, which is very similar to that found in Native Americans.

This suggests that Ancient North Siberians were key to the interbreeding and migration which led to Paleo-Siberians diverging and travelling across the Bering Strait from Siberia to North America to become the first Native Americans.

It is thought that ancient humans migrated across continents in pursuit of animals to hunt and due to other factors like climate change and avoiding confrontation with different groups.

The discovery of Ancient North Siberians has subsequently changed what we know about human migration as a whole.

The researchers think 40 people belonging to this group would have lived at the Yana site and they would have belonged to a wider population of around 500 people.

Stone tools, lots of animal bones and other evidence of human habitation have been found at the site.

This research has been published in the journal Nature.

The missing link is a non-scientific term that typically refers to transitional fossils. It is often used in popular science and in the media for any new transitional form that is discovered.

Tsk Tsk Tsk posting non-scientific terms in a scientific section of the forum !

One striking discovery was that Mal’Ta Boy’s genome showed affinities with both modern European and Native American populations, but not with modern East Asians. This suggests present-day Native Americans are likely descended from at least two source populations: one originating in East Asia and the other closely related to Mal’ta boy’s Central Siberian roots.

There is also the solutrean hypothesis, but I don't know enough about that. Might have been debunked.
