Humans and Denisovans had Similar Fingers

The study describes tip right-hand little finger, separated rest finger bone excavated 1 years ago. A digital reconstruction complete finger bone, phalanx, reveals Denisovans’ fingers were much more similar modern humans expected. “I’m happy we get something out,” says Eva-Maria Geigl, palaeogeneticist Institute Jacques Monod Paris, co-led study. “So far there nothing, phalanx lost.” Mum’s Neanderthal, Dad’s Denisovan: First discovery ancient-human hybrid Her team sequenced DNA missing fragment show matched rest fingertip bone, used photographs reunite two pieces published September Science Advances1. “It’s not going revolutionize knowledge Denisovan morphology, adds little piece,” says Bence Viola, palaeoanthropologist University Toronto Canada part team. Denisovan discovery. The mystery surrounding lost piece began remote valley foot Altai Mountains southern Siberia, Russian archaeologists excavating Denisova Cave uncovered finger bone belonging group ancient humans 2008. Anatoly Derevianko, archaeologist Russian Academy Sciences Institute Archeology Ethnography Novosibirsk leading dig, decided divide bone send pieces two labs see DNA extracted either half. One fragments went Svante Pääbo, evolutionary geneticist Max Planck Institute Evolutionary Anthropology Leipzig, Germany. His team sequenced DNA discovered bone belonged lineage distinct modern humans Neanderthals. In January 2010, Pääbo several his colleagues flew Novosibirsk. Use ancient remains more wisely. That’s Derevianko told Pääbo’s team he divided bone two sent half Edward Rubin, geneticist then Lawrence Berkeley National Laboratory (LBNL) California, se team been competing Pääbo’s sequence Neanderthal DNA. “We freaked bit,” remembers Viola, joined Pääbo trip. “We idea there second part.” Worried getting scooped, Pääbo his team raced report their discovery. They published fossil’s mitochondrial genome — short stretch maternally inherited DNA — March 20102. Several months later, they went reveal first complete nuclear genome Denisovan3.studies showed Denisovans were group extinct hominins were more closely related Neanderthals modern humans, they lived Siberian cave — probably across Asia — more 30,000 years ago.

Researchers have found more ancient-human bones cave, including stunning discovery first-generation hybrid, Neanderthal mother Denisovan father. But Viola — analysed nearly every Denisovan fossil cave — says he never forgot second finger-bone fragment. “I’ve been wondering le time half would have looked like,” he says. “All I knew Berkeley.” Revisiting old bones According Geigl, Rubin, left LBNL 201 industry not reached comment, sent his half fossil her lab 2010. Pääbo’s team already published fossil’s mitochondrial genome. But Geigl hoped obtain nuclear DNA fossil, indicate much more hominin’s relationship humans Neanderthals.

Move over, DNA: ancient proteins starting reveal humanity’s history Initial efforts extract DNA bone failed, Geigl’s team worked developing methods. But Pääbo team published Denisovan nuclear genome, Rubin asked Geigl return fossil. She returned fragment 2011, able sample DNA take detailed photographs first. Geigl sat data years, 2016, she decided publish them, suggestion Pääbo. Her team sequenced mitochondrial genome discovered — unsurprisingly — exactly matched sequence Pääbo’s team published 2010. But digital reconstruction complete finger bone held surprise: bone slim, more fingers modern humans stout digits Neanderthals, even Denisovans more closely related Neanderthals.few.

Denisovan remains been discovered, including large molar teeth, tend not resemble modern humans. “Given limited skeletal remains definitively associated Denisovans, important discovery,” says Tracy Kivell, palaeoanthropologist University Kent, UK, not involved study.slender shape Denisovan finger suggests Neanderthals’ burlier fingers have evolved result strenuous their hands, she adds. Although story missing fragment become clearer, current whereabouts still unknown. According Derevianko, Rubin sent sample ancient-DNA lab Eske Willerslev University Copenhagen Natural History Museum Denmark 201 2012. Willerslev did not respond requests comment Nature’s news team. Pääbo his team grind portion their piece bone produce high-quality genome sequence returned rest Derevianko, Geigl unsure half she analysed gone. “It’s Sherlock Holmes story,” she says

Another Pre-Human Detected in Papuan and Aboriginal DNA

Research shows Neanderthal man, Denisovan and another in DNA.
Paleontologist have all the answers about man. They have a complete map of the evolution of humans beings. If you think this way, you are wrong! Evolution to the present is just based on a few old bones.  Modern examination from other sources it changing established theory.  Neanderthal man Denisovan
Mortlock Islanders
Two prehumans are known: Neanderthals and Denisovans. However, genetic research has now shown that there are traces of another extinct human species in human DNA. Australian Aboriginals of north-east Australia and the people of Papua New Guinean carry these genes.
   Neanderthal man evolution
Astralo-Pacific people have about 2.8 per cent of Neanderthal in their genetic makeup. It was believed that another 6 per cent was from Denisovans. The latest research shows this estimate to be wrong. Only 1.11 is clearly Denisovan. This leaves 4+ per cent from another prehuman or maybe more sub-species.
   Neanderthal man.
Africa is truly our Garden of Eden.  Man is not the only species to have left Africa in steady waves. Neanderthals and perhaps Denovans left Africa too. It is believed that Denisovans were an off-shoot of Neanderthals. This should be treated very carefully, though. It could be the other way round!

Humans Crossing With Neanderthals and Denisovans is Rubbish

Much has been said about humans having mated with neanderthals. Scientists claim that all of us have Neanderthal genes. There is the real issue of humans and Neanderthal having a different number of chromosomes. It is known that if a horse is mated with a donkey, the result is an infertile mule. This holds true for all species, so how is it possible for two type of man who branched away from each other a very long time ago to have fertile offspring - the answer is it isn't possible.
Another issue is the premise that Denisovans mated with Man. There is little evidence for this. Currently, we do not know the number of chromosomes Denisovans had. Yet most scientists treat the mixing hypothesis as fact.

Can scientists be wrong? They have of course been very mistaken in times past and the present is no different. Why do specialists accept theories that have not been tested by the well know scientific method. It must be the case that most of them accept that Santa exists and lives at the North Pole.

There is another answer as to why Neanderthals, Denisovans and Humans have some of the same genes, but no one ever says it. We all have a common ancestor. Why couldn't there be some of the ancient genes from this ancestor present in each species?  Look in the mirror and see if you have a flat forehead and a large brow ridge.  You do?  Then join the club!
