New DNA Study Shows Humans Bred With Unknown Species
Denisovans interbred with yet another extinct population that lived in Asia more than 30,000 years ago — one that is neither human nor Neanderthal.
Updated genome sequences from two extinct relatives of modern humans suggest that these ‘archaic’ groups bred with humans and with each other more extensively than was previously known.
The ancient genomes, one from a Neanderthal and one from a member of an archaic human group called the Denisovans, were presented at a meeting on ancient DNA at the Royal Society in London. The results suggest that interbreeding went on between the members of several ancient human-like groups in Europe and Asia more than 30,000 years ago, including an as-yet-unknown human ancestor from Asia.
“What it begins to suggest is that we’re looking at a Lord of the Rings-type world — that there were many hominid populations,” says Mark Thomas, an evolutionary geneticist at University College London who was at the meeting but was not involved in the work.
The first published Neanderthal and Denisovan genome sequences revolutionized the study of ancient human history, not least because they showed that these groups bred with anatomically modern humans, contributing to the genetic diversity of many people alive today.
All modern humans whose ancestry originates outside of Africa owe about 2% of their genome to Neanderthals. Certain populations living in Oceania, such as Papua New Guineans and Australian Aboriginals, share about 4% of their DNA with Denisovans, members of a group named after a cave in the Altai Mountains in Siberia, Russia, where they were discovered. The cave contains remains deposited between 30,000 and 50,000 years ago.
At the meeting, however, David Reich, an evolutionary geneticist at Harvard Medical School in Boston, Massachusetts, who worked on those studies, said that the conclusions were based on low-quality genome sequences, riddled with errors and full of gaps. His team, along with collaborator Svante Pääbo at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has now produced much more complete versions of the Denisovan and Neanderthal genomes — matching the quality of contemporary human genomes. These high-quality Denisovan and Neanderthal sequences are both based on bones from the Denisova Cave.
The Denisovan genome indicates that the population got around: Reich said at the meeting that as well as interbreeding with the ancestors of Oceanians, they also bred with Neanderthals and the ancestors of modern humans in China and other parts of East Asia. Most surprisingly, Reich said, the genomes indicate that Denisovans interbred with yet another extinct population of archaic humans that lived in Asia more than 30,000 years ago — one that is neither human nor Neanderthal.
The meeting was abuzz with conjecture about the identity of this unknown population of humans. “We don’t have the faintest idea,” says Chris Stringer, a paleoanthropologist at the Natural History Museum in London, who was not involved in the work. He speculates that the population could be related to Homo heidelbergensis, a species that left Africa around half a million years ago and later gave rise to Neanderthals in Europe. “Perhaps it lived on in Asia as well,” says Stringer.
One day maybe kids will play with early hominid toys like they do dinosaurs now.
I would also be curious if we are forming new species now. When I was in college there was some question if people who lived their whole lives in high altitude could even breed with people at sea level.
I had one of those too. I couldn't shake her. Relentless she was. She didn't stop until I started going out with her best friend...who was quite cute. Go figure. But gorilla girl got the hint.
How's that for a peer review?
We have been fully human since God created Adam and Eve. Even though we have an ever-widening gene pool, we are still basically breeding within our same family. There are no "outsiders".
I believe it was Democratus Idotus, and there is a recessive gene that has become more dominant in some over the last couple of decades.
I hate it when stuff cross-pollinates in my vegetable garden.
Got no use for feral fruit.
Nephilim. The alien race that spiked our cocktail? I have always wondered.
If two "species" can inter-breed, then they are not distinct species, but rather just different races or breeds.
Consider canines. The various dog breeds can look very different from each other, with different temperaments and levels of intelligence, but still produce viable offspring with each other.
There they go again; "such large returns of conjecture from such small investment in fact." Next thing we know, we'll be told what they had for breakfast, and how independent the females were, and how abortion was not just tolerated, but required! and, of course, free birth control was not only rampant, but required.
Q.E.D.
It goes without saying that every perversion known (and now unknown) to man was rampant in the state of nature.
So these "scientists" soon will be are celebrating their lifestyles.
So we can all stop resisting and find confirmation and justification for the current pervert lifestyles, but imbued with special privileges. .
Nephilim and giant Philistines comes to mind.
They also spiked the football, for they apparently scored often.
They migrated across the Bering Straight and, although extremely rare, are now known as Sasquatch!!
Maybe the DNA of Democrats ought to be checked.
No, you saw pictures of a lot of people with that cross-bred DNA that day.
She so fine
Living proof that God has a sense of humor.
