Scientists may have a step forward in understanding how life on our planet came to exist. The mystery of how tiny molecules of RNA came to be enclosed within membranes, forming the very first cells, ...

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 ...
