Ghost in the shell: Never-before-seen extinct species of human found lurking in genes of today's West Africans, study finds

https://www.rt.com/news/480784-extinct-human-dna-found-africa/


A new study comparing the genomes of 405 West African people to Neanderthal and Denisovan sequences has revealed the “ghost” of a mysterious and previously unknown hominin that once lived alongside our ancestors.

The study, by Arun Durvasula and Sriram Sankararaman of the University of California, Los Angeles, published this week in the journal Science Advance, sequenced the genomes of people from four modern West African populations.


After feeding the detailed data into very powerful computers, and then cross-examining and comparing them to Neanderthal and Denisovan sequences (as well as other modern African genomes) a spectral presence faintly revealed itself. Hidden deep in the DNA code of present-day humans is evidence of an extinct human species, detectable only by a few tell-tale genetic markers lingering in their ancestors. 

Human, but not Homo sapiens

The study’s authors say that these genetic differences are best explained by hybridisation with an unknown humanoid. This suggests that ancestors of modern West Africans interbred with a yet-undiscovered species of archaic human – similar to how ancient Europeans mated with Neanderthals. 

Once, many species of humans roamed the Earth, of which Homo sapiens was just one. In 2014 a landmark genetic study revealed that human beings of European and Asian descent are not entirely human, as we had previously understood the term. That is, they are partial hybrids of at least three human species: Homo sapiens, Neanderthals and Denisovans. Denisovan DNA seems to be mostly found in Oceanian and some East-Asian populations, but basically everyone except sub-Saharan Africans has some Neanderthal DNA lingering in their cells, around 4 percent on average.


The researchers believe that the ancestors of this unknown archaic"ghost" hominin branched off from the modern human family tree before Neanderthals did. They even seem to have left their mark in modern populations to an even greater extent than Neanderthals: the amount of ‘ghost’ DNA in modern West African people ranged from 2 to 19 percent.

With the help of mathematical models and computer-aided number crunching, the team estimates that this archaic hominin split off from the ancestor of Neanderthals and modern humans between 360,000 and 1 million years ago. Then, from about 124,000 years ago, that break-off hominin reunited with the ancestors of modern West Africans and interbred with them, for an unknown period of time. They believe that the population of this introgressing hominin group was about 25,000 strong.

Although this is a simplified version of events – the separating and admixture of different populations and sub-species can be extremely muddled and complex – this is the most likely scenario that can be pieced together from the limited evidence. 


Out of Africa
One of the most remarkable things about the 2014 bombshell was that it proved that the only people on the planet who did not have any Neanderthal DNA were sub-Saharan Africans. This is because most of the interbreeding between different human species happened outside of the African continent, after the first humans had ventured out and began spreading to the rest of the world. Sub-Saharan African people’s ancestors have, as best we know, never left sub-Saharan Africa. But far from making them a uniform or an inbred population, they are in fact by far the most genetically diverse peoples on Earth. Just compare a Maasai warrior to a Congolese pygmy to a Ghanaian sprinter – there is more variation here than anywhere else on the planet.

European and Asian populations, although displaying a tremendous amount of morphological (physical) differences, from body size to facial shapes, are surprisingly inbred. But as the ancestors of European and Asian people migrated out of Africa, most would have died off in so-called ‘bottleneck’ events. Any number of new threats, from plague, to new predators or environmental catastrophes could have killed off swathes of the migrants, leaving only a few alive to reproduce and spawn the next generation.


1. No Neanderthal genes in subsaharan people including Yorubas
2. The sample for this study was drawn from Yoruba and Mende people
3. European and Asian populations are inbred, that is, they are full of inbreeding
4. Ghosts or Irunmoles or the Orishas

DNA analysis of people in West Africa reveals 'ghost' human ancestor

Four West African populations carry genes from what may be an undiscovered archaic hominin. This archaic group of humans seems likely to have diverged from the shared ancestor of Neanderthals, Denisovans and modern humans before these lineages split about 800,000 years ago.

Previous research has shown that Homo sapiens bred with Neanderthals and Denisovans after migrating from Africa, but little is known about the presence of genes from ancient hominins in people whose ancestors never left Africa, partly due to the difficulty of obtaining ancient DNA in hot climates where it can degrade.

To overcome these barriers, Sriram Sankararaman and Arun Durvasula at the University of California, Los Angeles, used computer modelling to compare gene variations in 405 West African genomes with those in Neanderthal and Denisovan genomes.

The team looked at both modern and ancient segments within the genomes of Yoruba people from Ibadan, Nigeria . They found more instances of genetic variation in the ancient segments than are seen in Neanderthal and Denisovan genes, suggesting that neither of these groups of ancient humans were the source of the genomic variance.

Similar patterns were seen in the genomes of Mende people in Sierra Leone, Esan people in Nigeria and those in western areas of Gambia . The four populations are estimated to derive between 2 and 19 per cent of their ancestry from an archaic group of genes.

We don’t know whether this archaic hominin is a “ghost”, for which we have no physical record, or one we have found traces of already, such as Homo heidelbergensis, which may have evolved around 700,000 years ago. “It’s a really intriguing question,” says Sankararaman.

This mystery hominin is most likely to have diverged from the ancestors of Neanderthals, Denisovans and modern humans before that lineage split into these groups, according to the researchers. They estimate this divergence took place at some point between 1 million and 360,000 years ago, and interbreeding between the archaic population and the ancestors of the modern populations occurred at some point in the past 124,000 years.

These findings complicate our understanding of human ancestry and the timing of when several branches evolved, much like the discovery of the Sima de los Huertos hominins in Spain, says Pontus Skoglund at the Francis Crick Institute in London. “Perhaps all this ties into something that we don’t fully understand, some complexity around the half-a-million year ago mark, or perhaps a bit more recently,” he says.

To discover more, we need more physical evidence, says Skoglund. “We might be able to find other hominins from Eurasia, where it is a bit colder with better DNA preservation, and they might let us understand the relationship between Neanderthals and modern humans in a better way.”

‘Ghost’ Ancestor Detected in DNA of Today’s West Africans

Yoruba and Mende have up to 19-percent genomic contribution from unidentified archaic human, who may have survived until recently. You might have a signal from it in your DNA too

https://www.haaretz.com/archaeology/.premium-ghost-ancestor-detected-in-dna-of-today-s-west-africans-1.8526887



An unknown hominin made a substantial contribution to the genome of modern West Africans, a new study has demonstrated. The genetic signal of this unknown ancestral species has been identified in four groups of West Africans, report Arun Durvasula and Sriram Sankararaman of the University of California, Los Angeles.

In fact, you may have a trace of this unknown archaic human as well. “Our study shows that some of this ancestry is also present in non-African populations,” Sankararaman tells Haaretz – it’s just less pronounced than in the West African groups.

He and Durvasula are in the process of testing other populations around Africa for the signal, he shares.

The interbreeding event in West Africa may have been quite recent in evolutionary terms, even though this new unknown species split off from the Homo line well over half a million years ago, before the split between Neanderthals and Homo sapiens, they reported Wednesday in Science Advances.

Specifically, by comparing the genomes of 405 West Africans with Neanderthal and Denisovan genomes and applying computer modeling, Durvasula and Sankararaman have discovered that contemporary Yoruba and Mende people derive between 2 to 19 percent of their genomes from this mysterious archaic hominin. In terms of averages, 6.6 percent of the Yoruba and 7 percent of Mende genome sequences are archaic, they calculate.

Their revelation comes years after the discovery that non-Africans contain genetic signals from Neanderthals and Denisovans. But in this case, the authors demonstrate by statistical methods that these sequences cannot have originated in Neanderthals, Denisovans or African populations such as the southern African Khoisan or central African pygmies.

Asked if Neanderthals might have had it too, Sankararaman explains that we can’t know at this stage. “Our methods require substantial sample sizes to detect this ghost population,” he says – and there is very little Neanderthal DNA around to work with, which is a challenge.

But who might it have been? Could this mysterious ghost have been a hominin not ancestral to Homo sapiens: a line that split off, but before going extinct, introgressed with the modern humans in West Africa? “That’s a very likely model,” Sankararaman answers.

Prehistoric liaisons dangereuses

We have long since debunked the assumption that our evolution was a linear progression from tree rat to monkey to ape to us, with only one species in the Homo line at a time. Not so. Only Homo sapiens ultimately survived. But throughout all our history until the last 30,000 years or so (maybe less), there were multiple coexisting humanoid species on the Homo tree.

For example, at least four types of australopithecinesoverlapped 4 to 2 million years ago, and the less said about our understanding of Homo erectus’ spread and lineages the better. 

It has also become clear that hominins weren’t too choosy about their love interests. In Eurasia, after Homo sapiens left Africa, they met and mixed with Neanderthals and Denisovans, many times. Neanderthals and Denisovans had a common ancestor, but after they split they also interbred: extraordinarily, a first-generation hybrid teenage girl resulting from just such a mix was found in Siberia. Remains of hybrid Neanderthal-Homo sapiens have been found in Israel.

This is why all non-Africans have some Neanderthal genes, typically between 1 to 2 percent. Many non-Africans – chiefly Melanesians, but in fact Asians in general (and the earliest Americans who came from Eurasia) – have Denisovan heritage too. Oceanic people have as much as 6 percent Denisovan contribution in their DNA.

Also: Hundreds of thousands of years ago, the shared ancestor of Neanderthals and Denisovans interbred with a “superarchaic” hominin that had separated from the Homo line about 2 million years ago.

More? Well, recent research found that after Neanderthals andHomo sapiens mixed in Europe, some hybrid Homo sapiens-Neanderthals went back to Africa and mixed with the Africans,resulting in a faint Neanderthal signal in them too. However, if in non-Africans the Neanderthal signal is usually around 1 to 2 percent of the genome, in the tested African populations the Neanderthal signal is about 0.3 percent.

On top of all this, several studies had indicated contributions from “deep lineages” to the ancestry of today’s Africans. But the extreme rarity of hominin fossils and the even more extreme difficulty in obtaining DNA from anything that died more than a week ago had hampered the research. Now the researchers have found the smoking DNA of a strange ancestor in the Yoruba and Mende, where the signal is loud and strong, and in some non-Africans, where the signal is weaker.

Once upon a time in West Africa

When might this mixing have happened? It likely was quite recent, also indicated by the fact that some West Africans have as much as 19 percent genomic contribution from this enigmatic ancestor.

Durvasula and Sankararaman estimate that the introgression event was about 43,000 years ago – though the potential margin of error is tens of thousands of years.

Therefore, the archaic may have survived, living contemporaneously with modern humans until recently, Sankararaman confirms.

“Alternately, it may have interbred earlier with a modern human population, which then interbred with the ancestors of present-day West Africans,” he tells Haaretz. There could have been a single interbreeding event, but a more realistic model would include low levels of gene flow over an extended period of time, they say.

Durvasula and Sankararaman deduce that the mystery hominin split from the Homo line about 625,000 years ago (mean), though their margin of error is again stupefyingly wide: 340,000 years to 1.02 million years.

Just to make the messy ancestry even more confusing, fossils evincing strange morphological combinations of archaic and modern features can be found from times as recent as 35,000 years ago in sub-Saharan Africa – at Iwo Eleru, Nigeria, andIshango in the Democratic Republic of Congo – and the Middle East, says the two-man team.

The bottom line is that people who were something other than “Homo sapiens sapiens” may have persisted much, much later than we usually assume.

Re: Sub Saharan People Do Not Have Neanderthal DNA by MrPresident1: 6:26am On Mar 07, 2020
The ancestors of the Europeans mated with Neanderthals. The Neanderthals do not possess a superior gene pool so this cannot be hybridisation, as apparently there was nothing to gain in this mating except a devaluation and degradation of the gene pool due to the introduction of inferior genes.

However, with the West Africans, it was hybridisation because in essence, it means that mere men mated with gods who had superior genes. The offspring of this hybridisation process would be super beings. In a nutshell, the West Africans, who are the offspring of the gods, are superior because they are the offspring of GOD.

There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.

As far as Neanderthals and denisovans are concerned the hybridization obviously did not produce desirable offspring as Homo Sapien offsprind remained more "sapient" and therefore its offspring having all the aptitude to survive over any hybrid with Neanderthal. The neandathals were however Human but of a different lineage and so did not develop so much speciation as to make it impossible to breed with their cousins the sapients

'Ghost' DNA In West Africans Complicates Story Of Human Origins

https://www.npr.org/2020/02/12/805237120/ghost-dna-in-west-africans-complicates-story-of-human-origins


About 50,000 years ago, ancient humans in what is now West Africa apparently procreated with another group of ancient humans that scientists didn't know existed.

There aren't any bones or ancient DNA to prove it, but researchers say the evidence is in the genes of modern West Africans. They analyzed genetic material from hundreds of people from Nigeria and Sierra Leone and found signals of what they call "ghost" DNA from an unknown ancestor.

Our own species — Homo sapiens — lived alongside other groups that split off from the same genetic family tree at different times. And there's plenty of evidence from other parts of the world that early humans had sex with other hominins, like Neanderthals.

That's why Neanderthal genes are present in humans today, in people of European and Asian descent. Homo sapiens also mated with another group, the Denisovans, and those genes are found in people from Oceania.

The findings on ghost DNA, published in the journal Science Advances, further complicate the picture of how Homo sapiens — or modern humans — evolved away from other human relatives. "It's almost certainly the case that the story is incredibly complex and complicated and we have kind of these initial hints about the complexity," says Sriram Sankararaman, a computational biologist at UCLA.

The scientists analyzed the genomes of 405 West Africans. Sankararaman says they used a statistical model to flag parts of the DNA. The technique "goes along a person's genome and pulls out chunks of DNA which we think are likely to have come from a population that is not modern human."

The unusual DNA found in West Africa isn't associated with either Neanderthals or Denisovans. Sankararaman and his study co-author, Arun Durvasula, think it comes from a yet-to-be-discovered group.

"We don't have a clear identity for this archaic group," Sankararaman says. "That's why we use the term 'ghost.' It doesn't seem to be particularly closely related to the groups from which we have genome sequences from."


The scientists think the interbreeding happened about 50,000 years ago, roughly the same time that Neanderthals were breeding with modern humans elsewhere in the world. It's not clear whether there was a single interbreeding "event," though, or whether it happened over an extended period of time.

The unknown group "appears to have split off from the ancestors of modern humans a little before when Neanderthals split off from our ancestors," he says.

Sharon Browning, a biostatistics professor at the University of Washington who has studied the mixing of Denisovans and humans, says "the scenario that they are discovering here is one that seems realistic."

Browning notes that the ghost DNA appears frequently in the genetic material. "That tells us that these archaic populations might have had some DNA that did some useful stuff that's proved to be useful to the modern population," she says.

But at the moment, Sankararaman says, it's not possible to know what, if any, role these genetic materials have for modern humans who carry them. "Are they just randomly floating in our genomes? Do they have any kind of adaptive benefits? Do they have deleterious consequences?" he added. "Those are all questions which would be fantastic to start thinking about."

He says there is likely evidence of other ghost populations in modern humans in other parts of the world. "I think as we get the genome sequences from different parts of the world at different points in time, there is always the possibility that we might discover these as-yet-unidentified ghost populations," Sankararaman says.

It's also possible that the ghost DNA found in this study comes from multiple groups, Browning added. "Within Africa, we don't know how many archaic groups might have been involved, and the study doesn't tell us that," she says. "It tells us that there was integration, but it could have been from more than one archaic population, in theory."

Compared with the Neanderthals, where there is abundant DNA fossil evidence, physical samples are much harder to come by in Africa. Browning says the climate on the continent has made it challenging.

"The conditions have to be right for the fossils to not totally disintegrate" in order to recover DNA, Browning says. Bones have been found in Africa from archaic populations, but no DNA has been recovered. Still, she adds, "the technology is continuing to improve, and people are still out there looking for more fossils."

So what happened to this mysterious group of ancient humans? Scientists aren't totally sure.

They might have died off, or they might have eventually been completely subsumed into modern humans.

‘Ghost DNA’ belonging to ancient extinct humans is still alive in the genomes of West Africans

A new lineage of humans has been identified in the DNA of certain African populations. But no one knows what they looked like or what happened to them.

by Tibi Puiu

February 13, 2020

Tens of thousands of years ago, modern humans may have interbred with a yet-to-be-identified related species. We know this because traces of this ancient interbreeding have been transmitted to the genomes of modern-day west African populations, according to a recent study.

Human evolution hasn’t followed a straight line but rather a series of divergent branches. Some of our ancestor’s lineages went extinct entirely, while others branched further.

It’s remarkable to imagine that at one point in time Homo sapiens shared this planet with at least four other lineages: Neanderthals, Denisovans, Homo floresiensis, and perhaps with Homo luzonensis (the latter still awaiting confirmation).

Now, a new study suggests that there may be a fifth lineage of humans. We haven’t found their fossils, but their genes are still very much etched in the genomes of certain west African populations. In some cases, up to a fifth of their DNA comes from these mysterious missing relatives.

The discovery was announced by a team of researchers led by Sriram Sankararaman, a computational biologist at the University of California, Los Angeles, in a new study published in Science Advances.

Sankararaman and colleagues sequenced the genomes of 405 individuals from four West African populations: two from Nigeria, one from Sierra Leone, and one from Gambia.

By employing statistical techniques, the researchers looked for markers of interbreeding that may have occurred in the distant past — turns out it did.

When they compared the African genomes with DNA from Neanderthals and Denisovans, the researchers found a huge chunk of DNA that came from an unidentified group of archaic humans. Their impact was highly substantial, ranging from 2% to 19% of the populations’ genetic ancestry.

“We don’t have a clear identity for this archaic group,” Sankararaman told NPR. “That’s why we use the term ‘ghost.’ It doesn’t seem to be particularly closely related to the groups from which we have genome sequences from.”

These ‘ghost’ people seem to have split from the common ancestor shared with Neanderthals and modern humans between 360,000 and one million years ago. According to the molecular genetic data, as many as 20,000 individuals belonging to this group of archaic humans interbred with the ancestors of modern West African humans at some point in the last 124,000 years.

We don’t know how these human relatives looked like or how they lived, but their genes paint a compelling story of complex interactions with our ancestors. In the process, our own story has suddenly become richer.

There is still much to learn. Next, the researchers plan to focus on some of these genes in order to tease out what they do. It’s very possible that many of these genes were kept across the generations because they provide an adaptive value to West African populations. What would prove to be a gold mine is finding fossils belonging to this mysterious extinct human relatives. Alas, that’s highly challenging since Africa’s climate is not kind on fossil preservation — but one can never know!

The researchers detected statistical anomalies they suggested were best explained by interbreeding between West Africans and an unknown ancient human lineage whose ancestors diverged from those of modern humans before the split between Neanderthals and modern humans. Four West African groups -- Yoruba in southwestern Nigeria, Esan in southern Nigeria, Gambians in western Gambia, and Mende in Sierra Leone -- may derive 2% to 19% of their DNA from a ghost lineage, the researchers said.

The key word here is "HUMAN" but an olodo like yourself simply misinterprets this very important point.

The "ghost" lineage is a paternal "HUMAN" Lineage A00 which is a sequence that is the oldest mutation YDNA detected in Africa. A mutation is simply a change in DNA sequencing that determines breaks in lineage ergo how we determine when one set of humans diverged from another set after developing changes in situ within a population.

A dog is of the Canine family of which I am no where close to in phyla.

If you said ape that would have been somewhat appropriate.

Like I said Yaba left nurses are very caring. They will help you.
