New research shows that ancient humans had sex with non human species. According to a study conducted by Omer Gokcumen, an assistant professor of biological sciences at the University of Buffalo, ancient humans had intercourse with a ghost species" of "proto human". Gokcumen explains that humans are only one member of a broader species named "hominins". The research found that humans had sex with other members of the hominins group. Gokcumen found "wildly different" genes in DNA of humans living in Sub-Saharan Africa. He believes these genes can be traced back to about 150,000 years ago when ancient humans were breeding with this mysterious "ghost species". This other species is referred to by the scientific community as a "ghost species" as there are no known fossils that can be analysed. "It seems that interbreeding between different early hominin species is not the exception - it's the norm," Gokcumen said. "Based on our analysis, the most plausible explanation for this extreme variation is archaic introgression - the introduction of genetic material from a 'ghost' species of ancient hominins."

Each news summary is created according to strict standards. Here's how we do it.
Each summary is created using a consistent editorial procedure. The target length is approximately 16 lines of 11-point Arial text in a 650-pixel-wide column. Up to 25% of a summary may be set in bold to emphasize the most important ideas. Summaries are composed of verbatim excerpts presented in the same sequence as they appear in the original news source, with very minor editorial additions. Where material has been omitted between excerpts, the omission is indicated with ellipses (...). Any words added by an editor for clarity or context appear in [brackets]. Our original news editor was Fred Burks. Tod Fletcher edited most summaries from 2007 through 2014, and Mark Bailey has served as news editor since 2014.
