which is true about the “denisovans”?

Why the heck do we have hundreds of Neanderthal fossils, but up to three subspecies that have left us only fragments and bones. The cave is known locally as Aju-Tasch, which means “bear rock” in Altay. What the Denisovans might have looked like has been one of the hottest debates in paleoanthropology since the discovery of this extinct human lineage back in 2010. L'homme moderne serait sorti d'Afrique il y a 125.000 ans. So did Neanderthals. By this time — more than 100,000 years ago — Neanderthals and modern humans had advanced cognitive abilities, indicated by the complexity of their tools and hunting strategies. “No one had suspected such a population was out there,” says geneticist Matthias Meyer, who worked on the specimen. “It couldn’t really happen any other way than interbreeding,” says Rasmus Nielsen of the University of California, Berkeley, a lead scientist of the discovery, which was published in Nature in 2014. LATEST IN DENISOVANS. They may be a different branch of recent human evolution. Sign up for our email newsletter for the latest science news. We have genetic evidence. They were only discovered about a decade ago, and we have found very few remains of them. The "Out of Africa" hypothesis suggests that … Does Genetic Diversity Aid Starling Invasions Around The World? That partial finger bone was the first evidence of the Denisovans, a distinct branch of the Homo family tree, whose members mated with both Neanderthals and modern humans during the past 100,000 years. They might even have been more than one subspecies. This might allow for the bones to be found much later. Researchers gather in the Eastern Gallery of Denisova Cave, a location that has yielded thousands of artifacts and bones, including all of the fragmentary fossils of Denisovans yet known. Let’s think, for a moment, about funerals. Neanderthals buried their dead in a fetal position in a hole. For right now, though, we don’t know anything about who these people were. Although ancient DNA analysis confirmed the bones were Neanderthal, a small segment of maternally inherited DNA is more closely related to Denisovans. This was considered a gift to nature. Now, there could be a treasure trove of Denisovan fossils and burials just waiting to be discovered. The body has to be buried quickly. The fossils belong to a collection of at least 28 hominins discovered at the bottom of a 40-foot cave shaft known as Sima de los Huesos, the “Pit of Bones.” The bones account for most of the human fossils ever discovered from the Middle Pleistocene, the period 120,000 to 780,000 years ago during which modern humans, Neanderthals and Denisovans split into distinct lineages. In the sterile ancient DNA lab at the Max Planck Institute in Leipzig, Germany, geneticist Matthias Meyer searches for clues to the Denisovans’ story in their genome. This would explain why we aren’t finding Denisovan fossils in Siberia, but what about wetter places where they also lived? This proved to belong to a previously unknown hominin lineage related to, but not the same as, the Neanderthals. Select all of the following which are true about Denisovans. The single finger bone was unusually broad and robust, well outside the variation seen in modern people. Well, except they aren’t. It is true that Asians have crossed the Bering Strait, then an unbroken land named Beringia, at various periods, during the Pleistocene, but the human invasion of America remains still insufficiently dated.
