[QUOTE]Originally posted by Doug M: [QB] [QUOTE]Originally posted by Archeopteryx: [qb] Hopefully better techniques to retrieve and analyze DNA from human remains will help to also see how those ancient people looked like. Already now they start to try to assess phenotype from DNA out of just fragments of skeletons, and soon perhaps also from eDNA. Interesting is that they tried to make some kind of reconstructions from the autosomal DNA from three of the Abusir specimens. See this thread: [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=15;t=013243#000000]Forensic and facial reconstructions[/URL] From the thread: [IMG]https://i.ibb.co/58fsXjM/Ancient-Egyptians-DNA-Phenotype.png[/IMG] Even the phenotype of the Denisovans has been predicted by DNA analysis [IMG]https://i.ibb.co/BBLjL49/Denisova-DNA.jpg[/IMG] [QUOTE] Now, in an impressive feat, Gokhman and his colleagues have mapped out a proposed Denisovan skeleton using information for 32 skeletal features encoded in DNA that was extracted from a pinky bone. The research, published today in the journal Cell, doesn’t give exact values for Denisovan proportions, but it does offer a comparative look at how this mysterious kind of hominin measured up against Homo sapiens and Neanderthals. [/QUOTE][URL=https://www.nationalgeographic.com/science/article/dna-reveals-first-look-enigmatic-human-relative]DNA reveals first look at enigmatic human relative - National Geographic 2019[/URL] [/qb][/QUOTE]That DNA study has been discussed here before and such techniques are not necessarily accurate. The only way to prove that this DNA based method works is to take random individuals from around the world and submit their DNA this process in the blind. Meaning have the labs run the DNA and see what skin color it predicts without them actually knowing anything about the individuals being sampled. Then compare their results with reality. The issue is that reconstructions are always going to be subjective in many aspects. That is why it is always to be taken with a grain of salt, not just for skin color but overall fleshy features and appearance. Beyond that, Denisovans arent humans and we know what the first humans in Asia looked like. That isnt really a mystery needing to be solved. Not to mention, we also know for a fact that black skin was always present in Northern Africa. The issue is when did white skin become dominant in North Africa, because a few immigrants doesn't change an entire population. And we know for a fact that Africans across the continent have variation in skin tones, without Eurasian influence. So light skin was always present to some degree in North Africa as well. Not to mention "North Africa" as a region covers thousands of square miles and it is impossible to claim that populations along the coast are representative of the entire region in time and space. Populations in Southern Algeria and Libya are on average much darker than those in the North of these countries and have been for quite some time. So lumping all people in Northern Africa together as having the same complexion is just not based on facts or reality. [/QB][/QUOTE]
