One newly described group of Neanderthals appeared to have never met their neighbors.
Scientists found a new lineage of the early humans that emerged about 100,000 years ago. They remained genetically stable for about 50,000 years ago and possessed genomes that differed from Neanderthals found elsewhere on Earth at that time, according to a report in the journal Cell Genomics.
Remarkably, the newly described Neanderthals lived within walking distance of the greater population. The findings have the potential to rewrite what we know about Neanderthals.
