Genome analysis suggests interbreeding between modern humans, Neanderthals, Denisovans and a mysterious archaic population.
New genome sequences from two extinct human relatives suggest that these
‘archaic’ groups bred with humans and with each other more extensively
than was previously known.
The ancient genomes, one from a Neanderthal and one from a different
archaic human group, the Denisovans, were presented on 18 November at a meeting at the Royal Society in London. They suggest that interbreeding
went on between the members of several ancient human-like groups living
in Europe and Asia more than 30,000 years ago, including an as-yet
unknown human ancestor from Asia.
“What it
begins to suggest is that we’re looking at a ‘Lord of the Rings’-type
world — that there were many hominid populations,” says Mark Thomas, an
evolutionary geneticist at University College London who was at the
meeting but was not involved in the work. [...] nature.com/
