Neanderthals and Denisovans, two "archaic humans" that are now extinct, were so closely related to our species that these three groups interbred within the last 40,000 years.
|
|
In an emerging model of evolution, widely supported by scientists, different types of early humans, including Neanderthals, interbred and left their genetic traces with many of us today.
|

|
|
But if a small party of human ancestors made its way into Europe, interbred with the Neanderthals, and left behind genetic traces in the mitochondria, that discrepancy might make sense.
|
|
These were the Neanderthals and Denisovans, archaic humans who interbred with those early moderns, leaving bits of their DNA behind today in the genomes of people of non-African descent.
|
|
We now know that homo sapiens and Neanderthals interbred, so the choice of a high forehead or widely set eyes would encourage us to mate solely with other homo sapiens.

|
|
Now a new study of global genomes, published this month in the journal Science, reports that our ancestors also crossed paths and interbred with another distinct hominid species known as the Denisovans.

|
|
Since 2009, studies have revealed that approximately 0003,000 to 60,000 years ago, some modern humans spreading out of Africa interbred with Neanderthals; they later did so with another ancestral human group, the Denisovans, as well.
|

But one new brew has emerged from a dark pond of secret herbs and interbred with barley, malt, and bubbles to create Fernetic, which, as one might guess, is a Fernet-Branca-inspired craft beer.
|
|
Up until now, the scientists wrote, a lack of understanding of the species as distinct has had the effect of "directly impairing scientific conservation management" -- including the potential for the two species to be interbred in captivity.
|
|
In addition to representing the oldest evidence of human interbreeding on record, the finding is also surprising because the two populations that mated were far less closely related than other human groups previously known to have interbred.
|
|
Whereas modern humans and Neanderthals had been on separate branches of the evolutionary tree for about 750,000 years when they interbred, the newly discovered population and the neandersovans had been separated for more than 1 million years.
|
|
WASHINGTON (Reuters) - Scientists have conducted a meticulous genetic comparison of humankind's closest living relatives, chimpanzees and bonobos, and found that much as humans once interbred with Neanderthals long ago these two ape species also were kissing cousins.
|
|
The story is a thinly veiled screed against miscegenation where the populace of Innsmouth have, in exchange for wealth, interbred with deep ones—think The Creature from the Black Lagoon—and now resemble half-people half-fish hybrids.
|
|
Photo: Cheburgenator/WikimediaGenetic analysis suggests two populations of Denisovans—an extinct group of hominids closely related to Neanderthals—existed outside of Africa during the Pleistocene, and that both of these populations interacted and interbred with anatomically modern humans.
|
|
Complicating the picture even further is the realization that some Denisovans interbred with Neanderthals, as evidenced by a 90,000-year-old fossil found in Denisova cave belonging to a female with a Neanderthal mother and a Denisovan father.
|
|
Genetic analysis makes it clear that there were at least two periods when Homo sapiens and Homo neanderthalensis (a species found only in Europe and Asia) interbred with one another: one 100,000 years ago, the other 50,000 years ago.
|
|
WASHINGTON (Reuters) - Scientists examining the genomes of West Africans have detected signs that a mysterious extinct human species interbred with our own species tens of thousands of years ago in Africa, the latest evidence of humankind's complicated genetic ancestry.

|
|
Also, the DNA data available for the Sima individuals isn't very complete, so even though their DNA might bear a resemblance to Neanderthals, it's possible that this group interbred with some other unknown hominins, resulting in the observed dental differences, according to Browning.
|
|
With different populations, methods, and approaches, each of these studies came to a similar conclusion: modern populations of non-Africans can trace the majority of their ancestry to a single migration of ancient humans out of Africa who then interbred with Neanderthals.
|
|
The list is large: Homo erectus could have interbred with Denisovans — another group of human ancestors found mostly in Siberia and east Asia — as well as two other early human species that lived on Pacific islands, called Homo floresiensis and Homo luzonensis.
|
|
The newly sequenced Vindija genome is important for another reason: because Neanderthals and anatomically modern humans are thought to have interbred roughly 50,000 to 60,343 years ago, the Vindija genome is a closer match to the Neanderthal DNA still found in modern human genomes today.
|
|
There was a big question about whether they interbred with modern humans and the DNA work, in which I was involved, showed definitively that they did interbreed with the ancestors of non-Africans (non-Africans contributed about 2% of the DNA over Africans living today).
|
|
But it would be a major achievement in the world of canine science, and a landmark in the analysis of ancient DNA to show evolution, migrations and descent, much as studies of ancient hominid DNA have shown how ancient humans populated the globe and interbred with Neanderthals.
|
|
They study large groups of people and analyze their genetic patterns with respect to ancestry: sometimes current ethnicities, sometimes historical, sometimes archaic humans and ancient DNA and deducing how people have moved around the world and when they've interbred and when they haven't, all these things.
|
|
Statistical models have helped scientists infer the existence of a couple of these populations without fossil data: For example, according to research published in late 2013, patterns of genetic variation in ancient and modern humans point to an unknown human population having interbred with Denisovans (or their ancestors).
|
|
How ancient genetic admixture events affected modern African genomes has been little studied — although a pair of researchers recently reported in PLOS Genetics that humans in Africa interbred with another ancient hominin group both before and after the ancestors of European and Asian populations split off and migrated away.
|
|
"As modern humans spread around the world, they interbred with Denisovans and Neanderthals, who had already been living in these different environments for hundreds of thousands of years," said Rasmus Nielsen, a professor of integrative biology at the University of California, Berkeley and an author of the paper.
|
|
During the Reagan decade, conservative Christian belief in the reality and power of Satan, the near-universal presence of electronic media in U.S. households, and cultural spillover from the paranoid style in American politics all interbred to birth an era uniquely repelled by and obsessed with the specter of evil.
|
|
However, by comparing DNA extracted from the finger bone to the genomes of people alive today, researchers have shown that Denisovans and Neanderthals shared a common ancestor sometime between 500,000 and 700,000 years ago, and that they interbred with each other and with the direct ancestors of H. sapiens on more than one occasion.
|
|
When a lab in Leipzig, Germany, sequenced the majority of a Neanderthal genome, in 2010, the scientists surprised just about everybody with the finding that humans and Neanderthals had actually interbred; we now know that most people, with the general exception of sub-Saharan Africans, can trace part of their genetic inheritance to our extinct cousins.
|
|
"From that information, however, I think what was most interesting to me was the evidence that ancient modern humans interbred with Neanderthals really early (we see this in the Neandertal genomes) during a time that was prior to when we think the big movement out of Africa occurred (that resulted in the colonization of the rest of the world by modern humans)," Stone told Gizmodo.
