| Who Were The Denisovans? Mysterious Extinct Hominin Species | |

| Who Were The Denisovans? Mysterious Extinct Hominin Species | |
| [quote]Denisovans are the first group of ancient extinct archaic | |
| humans to have been discovered based on their DNA alone, even | |
| though this happened by accident. | |
| In 2008 research was done in the Denisova cave by archaeologists | |
| from the Russian academy of Sciences during their investigation | |
| they discovered a finger bone from a teenage female hominin that | |
| was thought to have lived somewhere between 50.000 and 30.000 | |
| years ago. | |
| In total we have fossils belonging to 6 different distinct | |
| Denisovan individuals that were found in the Denisova Cave. | |
| These individuals have been identified through their DNA, and | |
| they are known as; Denisova 2, Denisova 3 who is also known as X | |
| Woman, Denisova 4, Denisova 8, Denisova 11 and Denisova 13. | |
| Denisova 11, or otherwise known as Denny, is of significance for | |
| a very different reason, the fossil belonging to her body was | |
| discovered in 2012. | |
| The fossil is a piece of either an arm or a leg bone and this | |
| was another adolescent female, approximately 13 years of age and | |
| she lived approximately 90.000 years ago. | |
| This is the only Denisovan and Neanderthal hybrid that we know | |
| of at this point in time. | |
| She is a 1st Generation archaic hybrid, research has uncovered | |
| that she had a Neanderthal Mother and a Denisovan Father. | |
| All Denisovan fossils came from this one location, the Denisova | |
| Cave in Siberia and their DNA was discovered to be carried by | |
| many people in Asia, Indonesia and all the way down south to | |
| Australia. | |
| But in 2019 a research group in China discovered that a partial | |
| mandible found in the Baishiya Cave on the Tibetan Plateau in | |
| China belonged to a Denisovan. | |
| They were not able to extract DNA from this bone, but they were | |
| able to do an ancient protein analysis that contained collagen | |
| and found this specimen had closes affiliation to the Denisovans | |
| from the Denisova Cave. | |
| The researchers discovered that the Mitochondrial DNA of | |
| Denisovans differ on 385 of the 16.500 bases, or nucleotides, | |
| with Modern Humans. | |
| To put this in perspective a bit, modern human and Neanderthals | |
| only differ on 202 of the 16.500 nucleotides. | |
| But this wasn�t the only type of DNA research that was done on | |
| the Denisovans, aside from the Mitochondrial DNA they also did | |
| Nuclear DNA testing and through that the researchers discovered | |
| that the Denisovans and Neanderthals were much more closely | |
| related to each other than both of them were related to modern | |
| humans. | |
| So what do we know about what Denisovans looked like? | |
| Well, as you can imagine there is little known about the Anatomy | |
| of the Denisovans, because we only have a small amount of | |
| physical remains and the ones that we do have are either small | |
| in size or teeth and therefore not indicative of their | |
| appearance. | |

| Ooops. This belongs in the human evolution thread, sorry. | |
