To extract ancient human chromosomal DNA from caves, Vernot and colleagues identified regions in chromosomes rich in mutations specific to hominids to help the team filter out nonhuman DNA. This helped the researchers successfully analyze Neandertal chromosomal DNA from more than 150 samples of sediment roughly 50,000 to 200,000 years old from a cave in Spain and two caves in Siberia.
After the team compared its data with DNA previously collected from Neandertal fossils of about the same age, the findings suggested that all these Neandertals were split into two genetically distinct waves that both dispersed across Eurasia. One emerged about 135,000 years ago, while the other arose roughly 105,000 years ago, with one branch of the earlier wave giving rise to all the later groups examined.
In the Spanish cave, the researchers found genetic evidence of both groups, with the later wave apparently replacing the earlier one. “There were signs based on the mitochondrial DNA of this turnover, but seeing it clearly with the nuclear DNA is really exciting,” says paleogeneticist Qiaomei Fu at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, who did not take part in this study.
The later wave may be linked with the emergence of the last “classic” stage of Neandertal anatomy, skeletal features such as a bulge at the back of the skull that may indicate strong neck muscles or enlarged brain regions linked to vision, the researchers say. This later wave may have coincided with cooling and other environmental changes that came with the advent of the last ice age, they note.

from the FRchives:The Scars of Evolution:"The most remarkable aspect of Todaro's discovery emerged when he examined Homo Sapiens for the 'baboon marker'. It was not there... Todaro drew one firm conclusion. 'The ancestors of man did not develop in a geographical area where they would have been in contact with the baboon. I would argue that the data we are presenting imply a non-African origin of man millions of years ago.'"

Butt butt, butt native tribes...........
Where are my reparations for the genocide upon my ancestors?
Too bad they cannot bring themselves to spell “Neanderthal” correctly...
“A few years ago, scientists showed that it’s possible to extract prehistoric human DNA from dirt, which contains genetic material left behind by our ancestors from skin flakes, hair or dried excrement or bodily fluids such as sweat or blood...”
Had no idea!
Perhaps you should take your inability to know what you’re talking about to another thread.
The forensics technology has made huge strides in just the past few years.
Neanderthal, (Homo neanderthalensis, Homo sapiens neanderthalensis), also spelled Neandertal, member of a group of archaic humans who emerged at least 200,000 years ago during the Pleistocene Epoch (about 2.6 million to 11,700 years ago) and were replaced or assimilated by early modern human populations (Homo sapiens) ...
Paging Jeff Goldblum....
Neanderthal is the more common spelling of the noun denoting the species of robust humanlike creatures that went extinct around 30,000 years ago. Neandertal is preferred by a few scientific publications. Neanderthal, the original spelling, was derived from the German valley where Neanderthal fossils were first discovered in the 19th century.
I remember. Cave prices skyrocketed.
What intrigues me more than origin location is how rapidly science has progressed. Just 100,000 years ago Neanderthals were running around. While earth is 5 billion years old.
So modern humans have been around for only about 0.00002 fraction of earth’s age. Will humans survive the remaining life of earth of 99.998% of earth’s remaining life?
In the North Rhine-Westphalia.
“Perhaps you should take your inability to know what you’re talking about to another thread.”
What??? I know exactly what I am talking about.
The Neanderthals and the Denisovans cohabited to a degree, which is an interesting theory all the way around.
They did - there are 2 accepted spellings - the first is the original German spelling prior to 1901; then it was changed to the latter spelling.

The origin of anatomically correct humans through mDNA dating has been pushed back to 300,000 BC. So the question arises, what were we modern humans doing for the 293,000 years before ‘modern history’ began?
I guess without guns, without anti-biotics, without decent shelters, without agriculture, they were simply busy surviving lions, lack of reliable food supply, covid-18 (lol), the ice age etc.
I trace the explosion of science to the invention of internal combustion engine. That freed up humans from drudgery work to have free time for thinking at higher levels.
