Skip to comments.A New Batch of Neanderthal Genome Provides Insights Into Their Complex History
Posted on 03/26/2018 3:35:09 AM PDT by SunkenCiv
People today of Native American, European, Asian, and North African heritage have Neanderthal DNA in their genomes, with percentages estimated between 1-4 percent. As a result, the majority of people alive today are related to these humans that, as a distinct population, are thought to have gone extinct 39,000-41,000 years ago.
An international team of researchers led by scientists from the Max Planck Institute for Evolutionary Anthropology has just overcome the problem, allowing for whole genome sequencing of five Neanderthals who lived 39,000-47,000 years ago. The findings, reported in the journal Nature, provide important insights into Neanderthal history before and after they encountered anatomically modern humans.
She and her colleagues took small bone and tooth samples from the remains and ground them into a fine powder. The powder was then treated with a mild, hypochlorite solution that preferentially removed the contaminating DNA.
The remaining genetic material was then sequenced and compared with the other Neanderthal genomes as well as related data for Denisovans and two anatomically modern humans whose lifespans and locations overlapped with those of the studied Neanderthals.
Since there is currently no genetic data available for Homo floresiensis, aka the "hobbit" human from the Indonesian island of Flores, it is not possible to determine how this group was related to Neanderthals and Denisovans.

The Neandertal Enigma"Frayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127]

I am curious as to how the hair and coloring for the Neanderthal model was derived. Was there a well-preserved specimen to work from? Are Neanderthals considered a separate species or a subspecies to homo sapiens (or homo erectus)?
LOL! Good one, SC!
I don't believe there is any sample of Neandertal hair, just their genes for hair color. DNA is a match -- 23 chromosome pairs. If you get your DNA done by 23andMe or Ancestry.com, etc, you have the option of checking (after you get your results) for archaic DNA.
There is some debate as to whether they were a distinct species of the Homo genus (Homo neanderthalensis) or a subspecies of Homo sapiens. *
I got started with Mazurki, his was the first to come to mind, because [blush] of that Gilligan's Island episode in which he appeared (the one where they travel to the other island, where the mad scientist has his lab). Then I thought of Anthony Quinn, then Olmos. Then I quit, because there are probably more who would work in that gallery. And believe me, I mean no harm to the fine gentlemen.
Ahead of our time in many ways ....
I’d rub noses with her!
Yep...that train of thought is often a Runaway, especially at times like this. I was right there with you, waiting to see who would show up next.
Of course, this was back when actors were entertainers and knew their craft.
They identified one Neandertal as having a mutation that would cause red hair, and it isn’t the one you find in humans.
There are professors and students here who look like that.

More explanations about the BLM farce?
Neandertals ARE HUMANs!
From 23andme, they noted that I’ve got a .1-percent bit of Neandertal in me. Course, they also said I had a .2-percent Afghan/Pakistan DNA element as well....which really stretches the imagination a bit to figure how that got into the mix.
Maybe every now and then, over the thousands of years, some marriages were not quite so “evolving” or “merging” and some individuals have still come through in our time with a larger than average contingent of the neanderthal genome, leading to the use of the epithet of calling someone a “neanderthal” as accurate in some cases. Maybe I’m joking?
