    Landmark new research that involves analyzing millions of DNA barcodes has debunked much about what we know today about the evolution of species.In a massive genetic study, senior research associate at the Program for the Human Environment at Rockefeller University Mark Stoeckle and University of Basel geneticist David Thaler discovered that virtually 90 percent of all animals on Earth appeared at right around the same time.More specifically, they found out that 9 out of 10 animal species on the planet came to being at the same time as humans did some 100,000 to 200,000 years ago."This conclusion is very surprising,"...

    Researcher He Jiankui said last week that he had altered embryos for seven couples during fertility treatments. He said two of the edited embryos were born healthy twin baby girls. Their DNA had been altered to try to make them resistant to infection with the HIV virus. There is no independent confirmation of what He says he did. Over the weekend, reports emerged in Chinese media that He was being kept under house arrest. He was last seen Wednesday during an appearance at a conference in Hong Kong. He's [His] employer, the Southern University of Science and Technology in Shenzhen,...

    There’s some additional bad news out there for the “party of science” (as the Democrats have taken to calling themselves) and particularly for transgender advocates. But even if you have no interest in such social justice topics, a new study published by geneticists in Israel is still pretty fascinating. The Liberty Council has a report this week on new research material coming from Israel’s Weizmann Institute of Science, where scientists have undertaken an exhaustive study of genetic differences between the two genders which go far beyond just what’s found in their 23rd chromosomal pair or what sorts of genitalia they...

    The English idiom "highbrow," derived from a physical description of a skull barely able to contain the brain inside of it, comes from a long-held belief in the existence of a link between brain size and intelligence. For more than 200 years, scientists have looked for such an association. Begun using rough measures, such as estimated skull volume or head circumference, the investigation became more sophisticated in the last few decades when MRIs offered a highly accurate accounting of brain volume.Yet the connection has remained hazy and fraught, with many studies failing to account for confounding variables, such as height...

    For a long time it was believed that a giant rhinoceros called Elasmotherium sibericum went extinct around 200,000 years ago — well before the Quaternary megafaunal extinction event, which saw the end of the woolly mammoth, Irish elk and saber-toothed cat. Now improved dating of fossils suggests that the species survived in Eastern Europe and Central Asia until at least 39,000 years ago, overlapping in time with the existence of early modern humans. Today there are just five surviving rhinoceros species, although in the past there have been as many as 250 species at different times.Weighing up to 3.5 tons, Elasmotherium...

    Way more sex happened between Neanderthals and the ancestors of modern humans across Europe and Asia than scientists originally thought, a new study finds. Scientists initially thought that interbreeding among the two groups was more isolated to a particular place and time — specifically, when they encountered each other in western Eurasia shortly after modern humans left Africa. This idea stemmed from the fact that the genomes of modern humans from outside Africa are only about 2 percent Neanderthal, on average. Subsequent research, however, has found that Neanderthal ancestry is 12 to 20 percent higher in modern East Asians compared...

    New research published in Science shows that our most recent common female and male ancestors could have been alive at the same time.Thousands of years ago, somewhere in Africa, lived a man who – probably – had no idea that he, among all the other men in his group, would go on to become humankind’s most recent common male ancestor. Scientists would call him “Adam.” Now, a new paper published in the journal Science significantly narrows the time during which Adam could have lived – about 120,000 to 156,000 years ago – putting him in about the same time period...

    Our ancestors bred with other species in the Homo genus, according to a study published today in the Proceedings of the National Academy of Sciences1. The authors say that up to 2% of the genomes of some modern African populations may originally come from a closely related species. Palaeontologists have long wondered whether modern humans came from a single, genetically isolated population of hominins or whether we are a genetic mix of various hominin species. Last year, an analysis comparing the Neanderthal genome sequence to that of modern H. sapiens showed that some interbreeding did take place between the two...

    All modern humans descended from a solitary pair who lived 100,000 to 200,000 years ago, scientists say. Scientists surveyed the genetic 'bar codes' of five million animals - including humans - from 100,000 different species and deduced that we sprang from a single pair of adults after a catastrophic event almost wiped out the human race. These bar codes, or snippets of DNA that reside outside the nuclei of living cells, suggest that it's not just people who came from a single pair of beings, but nine out of every 10 animal species, too

    MIT Technology Review ^ | November 25, 2018 | Antonio Regalado
    A daring effort is under way to create the first children whose DNA has been tailored using gene editing. When Chinese researchers first edited the genes of a human embryo in a lab dish in 2015, it sparked global outcry and pleas from scientists not to make a baby using the technology, at least for the present. It was the invention of a powerful gene-editing tool, CRISPR, which is cheap and easy to deploy, that made the birth of humans genetically modified in an in vitro fertilization (IVF) center a theoretical possibility. Now, it appears it may already be happening....

    A giant rhino that may have been the origin of the unicorn myth survived until at least 39,000 years ago - much longer than previously thought. Known as the Siberian unicorn, the animal had a long horn on its nose, and roamed the grasslands of Eurasia. New evidence shows the hefty beast may have eventually died out because it was such a picky eater. Scientists say knowing more about the animal's extinction could help save the remaining rhinos on the planet. Rhinos are in particular danger of extinction because they are very picky about their habitat, said Prof Adrian Lister...

    A team of Spanish and Portuguese researchers has carried out molecular genetic analysis of the Y chromosome (transmitted only by males) of the aboriginal population of the Canary Islands to determine their origin and the extent to which they have survived in the current population. The results suggest a North African origin for these paternal lineages which, unlike maternal lineages, have declined to the point of being practically replaced today by European lineages... Although contribution is now mainly European, scientists state that North African and Sub-Saharan contribution was higher in the 17th and 18th centuries. The explanation as to why...

    Research by a group of Montreal scientists calls into question one of the most basic assumptions of human genetics: that when it comes to DNA, every cell in the body is essentially identical to every other cell. Their results appear in the July issue of the journal Human Mutation. This discovery may undercut the rationale behind numerous large-scale genetic studies conducted over the last 15 years, studies which were supposed to isolate the causes of scores of human diseases.

    But hair sample could have been from a wandering mercenary. An early wave of migration into the New World and the Arctic has been identified by sequencing a genome from a frozen hair excavated in Greenland. Archaeological evidence shows that there were two waves of migration to Greenland starting 4,500 years ago, first with the Saqqaq and then the Dorset groups, collectively known as the Paleo-Eskimos. Later, around 1,000 years ago, came the Thule culture which led to the current native population. The relationship between these three groups has been uncertain. Some theories hold that Paleo-Eskimos derived from the populations...

    New research has revealed that agriculture came to Europe amid a wave of immigration from the Middle East during the Neolithic period. The newcomers won out over the locals because of their sophisticated culture, mastery of agriculture -- and their miracle food, milk. Wedged in between dump trucks and excavators, archeologist Birgit Srock is drawing the outline of a 7,200-year-old posthole. A concrete mixing plant is visible on the horizon. She is here because, during the construction of a high-speed rail line between the German cities of Nuremberg and Berlin, workers happened upon a large Neolithic settlement in the Upper...
  • Ancient DNA reveals male diffusion through the Neolithic Mediterranean route

    06/02/2011 5:26:34 PM PDT · by SunkenCiv · 21 replies
    The Neolithic is a key period in the history of the European settlement. Although archaeological and present-day genetic data suggest several hypotheses regarding the human migration patterns at this period, validation of these hypotheses with the use of ancient genetic data has been limited. In this context, we studied DNA extracted from 53 individuals buried in a necropolis used by a French local community 5,000 y ago. The relatively good DNA preservation of the samples allowed us to obtain autosomal, Y-chromosomal, and/or mtDNA data for 29 of the 53 samples studied. From these datasets, we established close parental relationships within...

    The archaeology of North Africa remains enigmatic, with questions of population continuity versus discontinuity taking centre-stage. Debates have focused on population transitions between the bearers of the Middle Palaeolithic Aterian industry and the later Upper Palaeolithic populations of the Maghreb, as well as between the late Pleistocene and Holocene. Results: Improved resolution of the mitochondrial DNA (mtDNA) haplogroup U6 phylogeny, by the screening of 39 new complete sequences, has enabled us to infer a signal of moderate population expansion using Bayesian coalescent methods. To ascertain the time for this expansion, we applied both a mutation rate accounting for purifying selection...

Nearby is one of the most complete repositories of written knowledge on the tick, dating back to Homer, 800 B.C. Hundreds of thousands more of the bloodsucking creatures are tucked away in government-issue metal filing cabinets. The Smithsonian's little-known U.S. National Tick Collection is stored in a former home-economics demonstration house at Georgia Southern University. The collection's curators, the world's foremost authorities of tick identification, are in charge of more than 1...
