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 digitally.work 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

Australian Aboriginal
Progenitor?
We were taught that anthropologists knew it all, and everything they held about human evolution was correct. Human lineage could be placed on a timeline This is now proved to be incorrect: Papuans came out of Africa much earlier than the 50,000 to 80,000 years assumption. These people left the continent of Eden at least 100,000 yrs ago. The Original African theory supposed an Eve living as far back as 200,000. | ▶ not. |◀ |

African man
Adam?
Professor Alan Wilson has put forward the hypothesis that Australasia could be the fountain place of Man. Aboriginals have the highest rate of genetic mutation of any "race". Mitochondrial evidence along the female line proves this. A colleague of Alan Wilson, Rebecca Cann, suggests the combining of two human lineages in Aborigines pushing modern Man back 400,000 yrs. | ▶ | stories not | ▶ |    

There is another big mystery: humans have always lived alongside dogs. The presumption is that Africans travelled all the way to the Indonesian Archipelago with canines, but did not take them to Australia - very odd indeed. The British brought dogs in the eighteenth century. Dingoes escaped from fishermen journeying from Southeast Asia only a few centuries before. The Asian dog is a dingo. | ▶ | not. | ▶ |   | ▶ | not dogs | ◀ |

Neanderthals and Denisovans Are in Heaven

Anthropology: Adam and Eve hominids in the Garden of Eden.
Humans were not alone on the evolutionary path. There would always be at least one more type of hominid existing nearby until the last 13,000 years (Hobbits). If the number of chromosomes was very close then fertile offspring were possible. The case for neanderthal closeness is still not yet known for sure. Some make bold claims about humans having neanderthal genes, but note that we did have a common ancestor.
"This is the Garden of Eden love, from the volcano God."
Take it with a pinch of salt about us being Neanderthal, Denisovan, human hybrids. This is fairytale stuff. Neanderthals were mainly in Europe and Denisovans were for the most part in southeast Asia. This would mean that humans from Africa would be genetically pure. However, the Neanderthal gene chains are also in them. Perhaps these genes are common to most hominids.

Only a few decades ago many scientists loudly proclaimed that people came out of Africa to populate the world only 80,000 years ago. This has now been pushed back to 200,000 years. When humans moved into Europe 40,000 years ago they did not have the largest brains. Neanderthals were hands down winners. Indeed, Homo erectus did draw and carve. And stone tools was old technology for 3 million years before the present.

Humans are not special. We did get down to a few dozen survivors at one time. It is just good luck for us that we are here and Neanderthals are not. Furthermore, perception of a God is not unique to humans. Burial practices go back 400,000 years. If there is an afterlife, expect to see a some Neanderthals and Denisovans walking around in heaven.
