Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

When scientists found the skull, named Yunxian 2, they assumed it belonged to an earlier ancestor of ours, Homo erectus, the ...

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

They detected clear chemical signatures in these remains, which indicated that lead exposure for these species dated back to at least two million years ago. Through high-precision laser-ablation ...

The genomes of a 5,200-year-old woman and three 4,000-year-old men yield clues about the founding of Celtic populations. New clues from ancient DNA reveal the remarkable effect of agriculture on ...

A lost chapter in human evolution has been revealed after an analysis of modern DNA found that we come from not one but two ancestral populations—ones that drifted apart and later reconnected long ...

The human gastrointestinal tract is in a constant state of flux; it hosts a diverse and dynamic community of microbes known as the gut microbiome, and is constantly exposed to things in the ...
