New study reveals Neanderthals faced a population crash 110,000 years ago A new study has uncovered a major genetic bottleneck in Neanderthals about 110,000 years ago, shedding light on their demographic history and potential causes for their extinction. The research was conducted by an international team of scholars and published in Nature Communications. They examined the morphology of the semicircular canals—structures in the inner ear responsible for balance—to track genetic diversity in Neanderthal groups over a span of almost 400,000 years. The researchers examined fossil specimens from multiple sites, such as Atapuerca in Spain, Krapina in Croatia, and other locations in Europe and Western Asia. What they found aligns with earlier ancient DNA studies, confirming the idea that later Neanderthals saw a dramatic decline in genetic diversity...

Did you know the 1st recognised #Neanderthal skeleton was initially believed to be a deformed #Russian?

In 1856, a skull was found near Düsseldorf. Anatomist August Mayer examined the #bones & concluded that the strong pelvis was the result of riding & that the pronounced brows were from worrying from pain. He thought him a Russian Cossack from the Napoleonic War.

Another anatomist, Hermann Schaaffhausen, had actually correctly identified the bones - but he wasn't popular.

This is a photo of the skull cap of "Neanderthal 1" - the fossil mentioned in the post. It shows the very upper part of a humanoid skull, including the brow bridge. The skull is a deep sand colour, looking somewhat uneven. The bones appear very thick. The brow bridge is very prominent, shaped almost like a rounded "m". The background is white.
This is a charcoal drawing of Hermann Schaaffhausen, the man who correctly identified the fossil but was dismissed due to being unpopular. It shows a man in his thirtieth or forties, from the mid 19 hundreds. He wears a jacket, waistcoat and white starched shirt, with a minimal collar and a small black bowtie. His face is round, somewhat overweight, and enclosed by a trimmed beard which covers his chin, cheeks and all the way to his ears. He has no facial hair otherwise. His hair is styled in an almost-bob, ending just above his ears. He has a deep parting on the right, with the rest combed over to the left. His eyes are small but lively, with gently shaped brows. His nose is average, neither up-nor down turned. His cheeks are overly full. His mouth has a large lower-than-upper lip and is set in a mild smile.

About 20% of the Neanderthal genome survives in modern humans, with about 1-4% of most people's DNA being such for people with ancestry outside sub-Saharan Africa, and about 0.3% for those with (recent) roots in sub-Saharan Africa.

But what would a person with all those 20% in their DNA be like? What would they look like? Any differences beyond the visible ones?

A Little Boy Found a Strange Stone on the Beach. Archaeologists Told Him It Was a Neanderthal’s Hand Ax.

The artifact is now on display at a museum in southern England. Experts say the find is “so rare that most qualified archaeologists would never find one themselves”.

An earlier review of 2022 studies on #Neanderthal #family life. Social structure according to #genetics looks like #patrilocal with #females moving out of groups.

We are close to 💯 per cent certain that #Homosapiens did the exact opposite -- daughters stayed with their mums, and sons-in-law came into the group to do #brideservice. We are so sure here because it's what #African #huntergatherers do. As a result, our lineage flourishes (thanks to grandmothers), Neanderthals dwindled (lack of grandmothers?) and numerous Neanderthal women could have moved into the incoming African origin groups.

NatureEarliest modern human genomes constrain timing of Neanderthal admixture - NatureModern humans arrived in Europe more than 45,000 years ago, overlapping at least 5,000 years with Neanderthals1–4. Limited genomic data from these early modern humans have shown that at least two genetically distinct groups inhabited Europe, represented by Zlatý kůň, Czechia3 and Bacho Kiro, Bulgaria2. Here we deepen our understanding of early modern humans by analyzing one high-coverage genome and five low-coverage genomes from ~45,000 year-old remains from Ilsenhöhle in Ranis, Germany4, and a further high-coverage genome from Zlatý kůň. We show that distant familial relationships link the Ranis and Zlatý kůň individuals and that they were part of the same small, isolated population that represents the deepest known split from the Out-of-Africa lineage. Ranis genomes harbor Neanderthal segments that originate from a single admixture event shared with all non-Africans that we date to ~45,000-49,000 years ago. This implies that ancestors of all non-Africans sequenced to-date resided in a common population at this time, and further suggests that modern human remains older than 50,000 years from outside Africa represent different non-African populations.

Ever since scientists discovered that most people on Earth have a small slice of Neanderthal in their DNA, they have been trying to figure out when and how it got there. Now, two research groups say humans interbred with Neanderthals for a limited period about 50,000 years ago as our ancient ancestors migrated out of Africa. But why did Neanderthals die out while humans survived? Read more from @NBCNews.

Neanderthals were the first fossil collectors, new evidence from Prado Vargas Cave reveals Recent findings from the Prado Vargas Cave in northern Spain have unveiled a remarkable aspect of Neanderthal behavior: their apparent inclination toward collecting non-utilitarian objects, much like modern humans. A study led by Marta Navazo Ruiz of the Universidad de Burgos and published in the journal Quaternary reveals that 15 marine fossils, dating back 39,800 to 54,600 years, were intentionally gathered and brought into the cave. Except for one fossil that showed evidence of being used as a hammerstone, the rest bore no signs of practical use, ornamentation, or modification. Their deliberate transport—often from sources over 30 kilometers away—suggests a deeper motivation, possibly tied to symbolic, aesthetic, or social practices...
