Sex With Aliens

Hey I know it sounds crazy but this is on Wikipedia now so it must be true.

Mystery humans spiced up ancients’ sex lives

Genome analysis suggests there was interbreeding between modern humans, Neanderthals, Denisovans and an unknown archaic population. Ewen Callaway

The ancient genomes, one from a Neanderthal and one from a member of an archaic human group called the Denisovans, were presented on 18 November at a meeting on ancient DNA at the Royal Society in London. The results suggest that interbreeding went on between the members of several ancient human-like groups 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.

The first published Neanderthal1 and Denisovan2 genome sequences revolutionized the study of ancient human history, not least because they showed that these groups bred with anatomically modern humans, contributing to the genetic diversity of many people alive today.
