Ancient DNA Reveals a Completely Unknown Population of Native Americans (sciencealert.com)
schwit1 shares the findings of a new study of 11,500-year-old bones: Sunrise girl-child ("Xach'itee'aanenh T'eede Gaay") lived some 11,500 years ago in what is now called Alaska, and her ancient DNA reveals not only the origins of Native American society, but reminds the world of a whole population of people forgotten by history millennia ago. "We didn't know this population existed," says anthropologist Ben Potter from the University of Alaska Fairbanks. "It would be difficult to overstate the importance of this newly revealed people to our understanding of how ancient populations came to inhabit the Americas." In a new study published this week, the team reports that a genetic analysis of sunrise girl-child's DNA shows she belonged to a forgotten people called the Ancient Beringians, unknown to science until now. Before now, there were only two recognized branches of early Native Americans (referred to as Northern and Southern). But when the researchers sequenced sunrise girl-child's genome -- the earliest complete genetic profile of a New World human to date -- to their surprise it matched neither.
Given the nature of this field of research -- and the scope of the new findings -- it's unlikely the new hypotheses will remain uncontested for long. But in the light of all the new evidence researchers are uncovering, it's clear the first settlers of America carried a more diverse lineage than we ever realized. "[This is] the first direct evidence of the initial founding Native American population," Potter says. "It is markedly more complex than we thought." The findings are reported in the journal Nature.

So, are these what they call the Clovis or "pre-Clovis" people or are we talking way before them?
It is unlikely they are Clovis. The Clovis people are genetic ancestors of Native Americans, while the girls in TFA are not. Also, the Clovis people lived in Montana and New Mexico about 13 kya, while these girls lived in Alaska 11.5 kya, so they likely arrived from Siberia after the Clovis migration.
Because we suspected that they existed, and because we knew that Beringia existed. Names had been coined.
Also, we don't know what they were called, Ancient Beringians is what they are called.
The summary and title of course are clickbait and should be ignored. The key phrase isn't "completely unknown" but "previously unproven."
Apparently it is news to people that the Irish have Semitic and North African admixture
This is true even of their traditional languages. Irish is Indo-European, while Semitic languages are in the unrelated Afro-Asiatic family. Yet the Celtic languages of Britain and Ireland share several key grammatical features with Semitic languages. Perhaps these features were shared alongside the mixture of genes.
