The Omo 1 Fossil is maybe the biggest mystery in human evolution - a 200,000 year old fully modern human.
After consulting with many experts, it is highly likely that the supposed 200,000 Year old Modern Human Omo 1 From Ethiopia is actually only 50,000 Years Old, a tall and slender Female with a Gracile skull slightly more robust than modern females, and the face and jaw was wrongly reconstructed as Male. So rather than a gracile early modern male, it is a slightly robust modern female.
1. The attachment point for neck muscles on the back of the skull is small compared to males.
2. The Vertical part of the Mandible (Ramus) is short, which indicates a Female (females usually have less prominent chins that males as well)
3. The Occipital (back bottom of the skull) is small, also indicating a small neck.
4. The Pelvis is 95% certain to be from female, and closely matches the Omo Tribe who currently live in the region
5. The teeth are fully modern but slightly more robust but there are no 3D scans
6. The skull was found associated with fauna including Wild Cattle. The tribes in the region are well known as cattle herders so this would date back thousands of years
7. The skull and skeleton were found together in an Open Air site and it is almost unheard of to find such a complete skeleton unless it was deliberately buried.
8. The skull is much more modern than the Skhul and Qafzeh skulls of the Levant which are 80k to 120k years old (especially the jaw). These are also the oldest known burials.
9. The height estimate of 6 feet and the slender build is incredible for an ancient human female, but the Omo Tribes are known for having women that are 6 feet tall and slender.
10. The skull cannot be directly dated, so it is dated using the soils it was buried, which makes precise dating impossible.
11. Omo 2 which is more archaic and closely resembles the Herto skulls was found in a different site and cannot be used to date this skull
12. Omo 1 site was originally dated to 37,000 years, then 130,000 years, then 195,000 years then 233,000 years...the site has never been tested to see if the fossil was intrusive to the site

Thanks watching! What do you think is a good example of what they looked like? I think it is difficult to find a good example of what they looked like because there was lots of variation based on location and time period.
Denisovans in the south likely looked totally different than Siberian Denisovans. For example if the Harbin skull is Denisovan, it would be very robust while if the Solo skulls from Java are "southern Denisovan" they would be much more gracile.
Neanderthals from 300,000 years ago would look very different from Neanderthals 40,000 years ago. Some Neanderthals were very heavily admixed with Homo sapiens especially in the Middle East, while some had very little HS admixture.
Their skin color would probably match the latitude they lived because they were likely adapted for several hundred thousand years to their latitude and environment.
As for personal adornment, I think it is more likely that they adorned themselves with body paint at least and more likely tattoos, feathers, furs, and jewelry. I don't think they looked like homeless people, all disheveled and not caring about their appearances. The men would want to look fierce and the women would want to be pretty, just like today.
As for their physique, I think they would more likely be very muscular than thin and wiry, except for more recent Homo sapiens in East Africa. In colder climates they would have needed to be very muscular because they were not chasing game for miles across a hot African savannah. They were ambush hunters.
Just look at a Male chimp or a gorilla to see what a Male hominid who has not been totally emasculated should look like.

So, modern humans only took 30,000 years to evolve light skin but Neanderthals lived in Europe 300,000 years and never evolved light skin? Otzi had dark brown skin, not black skin, comparable to Middle-Easterners and North Africans today. The same was true for Cheddar Man and other WHG.
https://www.newscientist.com/article/2161867-ancient-dark-skinned-briton-cheddar-man-find-may-not-be-true/
"MC1R is a receptor gene that controls the production of melanin, the protein responsible for pigmentation of the hair and skin. Neanderthals had a mutation in this receptor gene which changed an amino acid, making the resulting protein less efficient and likely creating a phenotype of red hair and pale skin."
https://humanorigins.si.edu/evidence/genetics/ancient-dna-and-neanderthals
When you say "African skin" tone, that is an extremely biased statement because Africans have a wide range of skin tones, from brown to black. You should read this study to better understand skin tone, which is related to Latitude, and not politics.

According to Prof. Chris Stringer, world expert on ancient humans, who I contacted about this information, there is a soon to be published study that backs up the dates that Erectus and Sapiens overlapped in Java. I don't know what you mean that the 1996 study dates are not confirmed. There is disagreement, but that does not mean that older research is wrong.
Erectus varies widely between Africa, Indonesia, and China and the Java Erectus seem to be the most advanced, and lived the longest, so you cannot compare them all across time and space. Anthropologists cannot even agree what specimens should be included as Erectus, such as the fossils from Georgia, so you cannot say that all Erectus had the same capabilities.

According to a recent study, Black skin is actually a more recent trait (and therefore more advanced) while light skin is the ancestral state of the ape.
"The latest findings suggest that some particularly dark skin tones evolved relatively recently from paler genetic variants, underlining how deeply flawed the racist concept of people with whiter skin being “more advanced” really is."
https://www.newscientist.com/article/2150253-gene-study-shows-human-skin-tone-has-varied-for-900000-years/
There are many different genes that effect skin tone, so saying that "white skin did not appear until 12,000 years ago" only means that the gene responsible for white skin in modern humans evolved 12,000 years ago. Light skin has always been around, just using different genes. So ancient humans such as Neanderthals would not have the exact same pigmentation genes as modern humans because genes are always mutating, and like you say you cannot predict 100% what a person's pigmentation is based on a single gene.
The idea that a hominin living in a northern Ice Age climate for 500,000 years had dark skin goes against the laws of nature.
" Most of the genetic variants associated with light and dark pigmentation from the study appear to have originated more than 300,000 years ago, and some emerged roughly 1 million years ago, well before the emergence of modern humans. The older version of these variants in many cases was the one associated with lighter skin, suggesting that perhaps the ancestral state of humans was moderately pigmented rather than darkly pigmented skin."

@jasonborn867 The A00 haplogroup was described by Fernando Mendez and colleagues back in 2013 (https://doi.org/10.1016/j.ajhg.2013.02.002). It is a Y chromosome branch that seems to diverge from the rest of the modern human Y chromosome tree between 240,000 and 580,000 years ago. It’s found today in some Mbo men from present-day Cameroon, and some African-American men.
That’s very early compared to the rest of the Y chromosome tree. It is not very early compared to the autosomal genome, which shows that African populations started to become genetically differentiated around 300,000 years ago or so.
There’s a suspicion that this haplogroup may have entered recent human populations by interbreeding with a more ancient, diverged branch of archaic humans. It’s possible. The story of African “archaic” humans today is intricate, because we have just enough data to raise questions and not enough data to answer those questions.
The A00 haplogroup does not seem to mark that early diversification, because it isn’t present in Khoesan as far as we know.

Mendez and colleagues reported the identification of a Y chromosome haplotype (the A00 lineage) that lies at the basal position of the Y chromosome phylogenetic tree. Incorporating this haplotype, the authors estimated the time to the most recent common ancestor (TMRCA) for the Y tree to be 338 000 years ago (95% CI=237 000–581 000). Such an extraordinarily early estimate contradicts all previous estimates in the literature and is over a 100 000 years older than the earliest fossils of anatomically modern humans. This estimate raises two astonishing possibilities, either the novel Y chromosome was inherited after ancestral humans interbred with another species, or anatomically modern Homo sapiens emerged earlier than previously estimated and quickly became subdivided into genetically differentiated subpopulations. We demonstrate that the TMRCA estimate was reached through inadequate statistical and analytical methods, each of which contributed to its inflation. We show that the authors ignored previously inferred Y-specific rates of substitution, incorrectly derived the Y-specific substitution rate from autosomal mutation rates, and compared unequal lengths of the novel Y chromosome with the previously recognized basal lineage. Our analysis indicates that the A00 lineage was derived from all the other lineages 208 300 (95% CI=163 900–260 200) years ago.
