A girl goes nose-to-nose with a Neanderthal statue in Germany. Ancient DNA research is increasingly revealing the genetic links between modern humans and our extinct ancestors, including Neanderthals and the mysterious Denisovans.A new, improved sequencing of ancient human relative genomes reveals that Homo sapiens didn't only have sex with Neanderthals and a little-understood line of humans called Denisovans. A fourth, mystery lineage of humans was in the mix, too.
As reported by the news arm of the journal Nature, new genetic evidence suggests that several hominids — human relatives closer than humans' current living cousin, the chimpanzee — interbred more than 30,000 years ago. This group of kissing cousins included an unknown human ancestor not yet revealed by the ancient DNA record.
"It's implied it could be something like Homo erectus or similar," said Carles Lalueza-Fox, a paleogenomics researcher at Pompeu Fabra University in Spain, who was not involved in the research, but who was present at a talk on the findings given by lead author David Reich of Harvard Medical School at a meeting on ancient DNA sponsored by the Royal Society in London on Nov. 18. Homo erectus is an extinct species of human that originated in India and spread into Asia.
