Scientists from UC Berkeley have discovered genetic remnants of two previously unidentified human lineages embedded in contemporary DNA. One lineage, referred to as a 'ghost' lineage, interbred with early modern humans in Africa over 50,000 years ago, contributing approximately 0.5% to 1% of today's genome. The second lineage, labeled as 'super-archaic,' dates back around 1.8 million years and seems to have intermingled with Denisovans before its DNA was passed on to modern humans. Featured in Science, these revelations shed light on the intricate web of ancient human evolution.
