The caves suited the Neanderthals' purposes especially well because they lived in very small groups of about a dozen individuals. Few caves could support a larger population. There is evidence that in at least one case, Neanderthals and early humans lived in the same cave at the same time ...
A Neanderthal spear is predominantly made up of two parts, a piece of flint for the point, and a stick for the shaft. But one aspect is often overlooked, and has recently been puzzling archaeologists: the glue that fixes the point to the shaft. For this, Neanderthals used tar from birchb...
The research team report inNature Communicationson September 7, 2021, that humans in populations in Europe reproduced on average at a younger age than populations from east Eurasia and America over the past 40,000 years. “We estimate a difference of 3 to 5 years between the mean generation ...
The study, published in the journalCell, compared ‘brain organoids’ — 3D tissues grown from stem cells which model early brain development — that were grown from human, gorilla, and chimpanzee stem cells. Similar to actual brains, the human brain organoids grew a lot larger than the orga...
The genomes of humans and Neanderthals differ little; the two groups have fewer than 100 proteins that differ in their amino acid sequence. DNA sequences alone give little indication of whether the gene was active or not. In contrast, epigenetic chemical signatures can sometimes differ between gen...
Homo sapiens coexisted with earlier hominids such as Neanderthals. With their greater intelligence and organization, Homo sapiens out-competed other pre-human species for resources, enjoyed greater reproductive success and eventually replaced them. A competing theory suggests that pre-humans that had ...
the world andNeanderthalsand Denisovans disappeared. Exactly why they went extinct is another great mystery, but it seems likely that our species played its part. Interactions weren’t entirely hostile, though:DNAevidence shows that modern humans sometimesinterbred with both Neanderthals and Denisovans....
