Most non-Africans possess at least a little bit Neanderthal DNA. But a new map of archaic ancestry--published March 28 in Current Biology--suggests that many bloodlines around the world, particularly of South Asian descent, may actually be a bit more Denisovan, a mysterious population of hominids that lived around the same time as the Neanderthals. The analysis also proposes that modern humans interbred with Denisovans about 100 generations after their trysts with Neanderthals.
The Harvard Medical School/UCLA research team that created the map also used comparative genomics to make predictions about where Denisovan and Neanderthal genes may be impacting modern human biology. While there is still much to uncover, Denisovan genes can potentially be linked to a more subtle sense of smell in Papua New Guineans and high-altitude adaptions in Tibetans. Meanwhile, Neanderthal genes found in people around the world most likely contribute to tougher skin and hair.
"There are certain classes of genes that modern humans inherited from the archaic humans with whom they interbred, which may have helped the modern humans to adapt to the new environments in which they arrived," says senior author David Reich, a geneticist at Harvard Medical School and the Broad Institute. "On the flip side, there was negative selection to systematically remove ancestry that may have been problematic from modern humans. We can document this removal over the 40,000 years since these admixtures occurred."
Reich and lab members, Swapan Mallick and Nick Patterson, teamed up with previous laboratory member Sriram Sankararaman, now an Assistant Professor of computer science at the University of California, Los Angeles, on the project, which found evidence that both Denisovan and Neanderthal ancestry has been lost from the X chromosome, as well as genes expressed in the male testes.

They theorize that this has contributed to reduced fertility in males, which is commonly observed in other hybrids between two highly divergent groups of the same species.
The researchers collected their data by comparing known Neanderthal and Denisovan gene sequences across more than 250 genomes from 120 non-African populations publically available through the Simons Genome Diversity Project (there is little evidence for Neanderthal and Denisovan ancestry in Africans). The analysis was carried out by a machine-learning algorithm that could differentiate between components of both kinds of ancestral DNA, which are more similar to one another than to modern humans.
The results showed that individuals from Oceania possess the highest percentage of archaic ancestry and south Asians possess more Denisovan ancestry than previously believed. This reveals previously unknown interbreeding events, particularly in relation to Denisovans. In contrast, Western Eurasians are the non-Africans least likely to have Neanderthal or Denisovan genes. "The interactions between modern humans and archaic humans are complex and perhaps involved multiple events," Reich says.
The study's main limitation is that it relies on the current library of ancient genomes available. The researchers caution against drawing any conclusions about our extinct human ancestors based on the genetics and possible traits that they left behind. "We can't use this data to make claims about what the Denisovans or Neanderthals looked like, what they ate, or what kind of diseases they were susceptible to," says Sankararaman, first author on the paper. "We are still very far from understanding that."

A man pulled over in a routine traffic stop found himself behind bars over a long-overdue copy of the Tom Green comedy “Freddy Got Fingered.”
“That’s what my local law enforcement officers are up to,” he says in the video. “They’re not out here catching heroin dealers".
The North Carolina man, James Meyers, was pulled over for a broken brake light. When the Concord, NC officers ran a check on his driver’s license it showed an outstanding warrant for a movie he had rented and failed to return — in 2002.
The Rowan County warrant remains open, according to the report, and Meyers is liable for a fine. He’s due in court on April 27 to answer the charge of failure to return hired property, a misdemeanor.
The film in question, “Freddy Got Fingered,” starring comedian Tom Green and actor Rip Torn, was a relatively new release at the time. The video shop, J&J Video in Salisbury, North Carolina, has since closed.

We don’t really understand that either, but we imagine Belgian authorities will be discussing the issue quite a bit in the weeks and months ahead because it’s now emerged that on Thursday, Didier Prospero was shot and killed while walking his dog in Charleroi (about an hour drive from Brussels). Why should you care about Didier? Well, because he is (or “was”) a security guard at Tihange. His security pass was stolen as he lay dying.
“The murder was completely ignored and was committed on Thursday night in the judicial district of Charleroi,” Derniere Heure reported. “A security guard, accompanied by his dog, was shot in the early evening. His badge was stolen.”

>A new study finds that the Ice-Age diet -- a high-protein intake of large animals -- triggered physical changes in Neanderthals, namely a larger ribcage and a wider pelvis.
Homo sapiens, the ancestor of modern humans, shared the planet with Neanderthals, a close, heavy-set relative that dwelled almost exclusively in Ice-Age Europe, until some 40,000 years ago. Neanderthals were similar to Homo sapiens, with whom they sometimes mated -- but they were different, too. Among these many differences, Neanderthals were shorter and stockier, with wider pelvises and rib-cages than their modern human counterparts.
But what accounted for these anatomical differences? A new Tel Aviv University study finds that the Ice-Age diet -- a high-protein intake of large animals -- triggered physical changes in Neanderthals, namely a larger ribcage and a wider pelvis.
According to the research, the bell-shaped Neanderthal rib-cage or thorax had to evolve to accommodate a larger liver, the organ responsible for metabolizing great quantities of protein into energy. This heightened metabolism also required an expanded renal system (enlarged bladder and kidneys) to remove large amounts of toxic urea, possibly resulting in a wide Neanderthal pelvis.
Seeing evolution from a new angle
"The anatomical differences between the thoraxes and pelvises of Homo sapiens and Neanderthals have been well-known for many years, but now we're approaching it from a new angle -- diet," said Prof. Avi Gopher. Prof. Gopher, Prof. Ran Barkai and PhD candidate Miki Ben-Dor, all of TAU's Department of Archaeology and Ancient Near Eastern Cultures, co-authored the study, which was recently published in the American Journal of Physical Anthropology.
https://www.sciencedaily.com/releases/2016/03/160329132245.htm
"During harsh Ice-Age winters, carbohydrates were scarce and fat was in limited supply. But large game, the typical prey of the Neanderthal, thrived," said Ben-Dor. "This situation triggered an evolutionary adaptation to a high-protein diet -- an enlarged liver, expanded renal system and their corresponding morphological manifestations. All of these contributed to the Neanderthal evolutionary process."
"In a 2011 paper, which dealt with the demise of Homo erectus in the Levant, we had already tapped into the notion that diet played a major role in human evolution," said Prof. Barkai. "We argued then that high fat consumption was one of the most important solutions to the predicament presented by human evolution. Humans are limited in the amount of protein they are able turn into energy -- protein provides just 30 percent of their overall diet. The solution, therefore, was to consume more fat and more carbohydrates when they were seasonally available.
"We found that, in the case of the Neanderthals, an acute shortage of carbohydrates and a limited availability of fat caused their biological adaptation to a high-protein diet."
The proof in the dietary pudding
Numerous animal experiments have already demonstrated that a high-protein diet is likely to produce enlarged livers and kidneys. "Early indigenous Arctic populations who primarily ate meat also displayed enlarged livers and the tendency to drink a lot of water, a sign of increased renal activity," said Ben-Dor.
According to the researchers, the total dependence of Neanderthals on large animals to answer their fat and protein needs may provide a clue to their eventual extinction, which took place at the same time as the beginning of the demise of giant animals or "Megafauna" in Europe some 50,000 years ago. The team is now researching this subject.

>Texas scientists have found the oldest confirmed site of human habitation in the Americas just north of Austin, where the Edwards Plateau meets the coastal plains.
>The unprecedented haul of artifacts from as far back as 15,500 years ago brings archaeologists much closer to answering the mysteries of who the first Americans were, where they came from and how they got here.
>The new work, published Thursday in the journal Science, may definitively prove humans lived in the Americas prior to the “Clovis” people, who spread widely across the western hemisphere beginning about 13,000 years ago.
>These people, identifiable by their characteristic fluted spear points, long were thought to be the first Americans.
>The discovery of such an old settlement also suggests the first Americans must have come from Asia, not through an ice-free corridor over land, but along the Alaskan and Canadian coasts in boats as long as 16,000 years ago.
>“I think we’re getting closer and closer to understanding how and when the first people came into the Americas,” said Michael Waters, a Texas A&M University archaeologist who led the study.
>Waters and his colleagues found the trove of some 15,000 stone artifacts about 50 miles north-northwest of Austin at the Debra L. Friedkin site along Buttermilk Creek.
...
>>35115
>Fed by permanent springs, this area between the Edwards Plateau and lower coastal plains would have offered ample game from both ecosystems, and its limestone held an abundant supply of flint-like rock, or chert, ideal for making Stone Age tools.
>Since the 1930s, archaeologists have believed the ancestors of the Clovis people —so named for a small number of stone “points” found near Clovis, N.M. — walked into North America from Asia across the Bering Sea landmass as the last Ice Age waned about 13,500 years ago.
>They feasted on large game unaccustomed to human predators and possibly contributed to the extinction of animals such as the mammoth. They followed this game and quickly spread throughout the continent. Eventually the Clovis technology gave way to varied, ancient Indian peoples.
>This is the story long told in textbooks and museums.
>In recent years, however, this “Clovis first” theory has come under mounting attack by some archaeologists, linguists and geneticists who suggest people may have been in this hemisphere for far longer, predating the Clovis by thousands of years.
>Some sites in Virginia and Pennsylvania have produced artifacts that archaeologists claim show evidence of habitation 15,000 to 17,000 years ago. But this evidence, generally measured in dozens of artifacts rather than thousands, hasn’t convinced some Clovis-first archaeologists.
>The new evidence, however, is difficult to dismiss. Waters’ team found the thousands of older artifacts in sediments beneath a layer of Clovis artifacts. The design of the older points is cruder than Clovis technology, but there are enough similarities to suggest Clovis points were derived from the older points.
...
>“Some people will say this is the final nail in the coffin for the Clovis-first theory,” said Gary Haynes, a professor of anthropology at the University of Nevada at Reno, who long has been skeptical of pre-Clovis peoples in the Americas. “I don’t think this is the last nail, but I do think they’ve done some pretty good work here.”
>Haynes said he still has questions about the accuracy of the dating of sediments — without carbon-based material it’s difficult to get precise estimates of dates — and he has concerns that artifacts from later eras could have slipped down into older sediments.
>But Lee Nordt, a co-author of the Science paper and a geologist at Baylor University, dismissed that concern. He said there’s no evidence of such post-burial redistribution in the sediments.
>“They demonstrated to us unequivocally that the peopling of the Americas occurred prior to Clovis times and more than 13,000 years ago,” Nordt said.
>If Waters’ conclusions are correct, the first Americans evidently were handy with boats.
>Prior to about 13,500 years ago, sheets of ice two miles thick covered nearly all of Canada, making a land route impassable.
>The most plausible solution is that the first Americans traveled a coastal route, using boats to come down the Alaskan and Canadian coasts, parts of which probably would have been free of ice.
>There is little archaeological evidence of this trek, however.
So native americans are just boat asians?

The Chief Information Technology
Officer with the UN, Atafeh Riazi,
said in an interview as to how she
is planning to secure the dark web.
She said that Digital Blue Helmets,
an expert group to be set up, would
be of great help in foiling the ill
effects being caused by the
activities on the dark web.
According to the UN CITO, the
need to set up an expert group has
arisen because of the changes that
have come about in the cyber
world.
She noted that Digital Blue Helmets
would act as the peacekeepers of
the cyberspace.
Operating in the cyber world, the
experts group would protect the UN
from cyber intrusion.
The group would also support the
UN in delivering their missions in
the cyberspace.
In fact, Riazi’s plan is to create a
“light web” with the help of Digital
Blue Helmets and counter the
operators in the dark web.
Further, the UN plans to reorganize
its logistics and invest in security
tools and solutions so that the team
becomes equipped to handle both
the IT and operations sides.
