An ancient jawbone discovered in Taiwan belonged to an enigmatic group of early human ancestors called Denisovans, scientists reported Thursday.
Relatively little is known about Denisovans, an extinct group of human cousins that interacted with Neanderthals and our own species, Homo sapiens.
"Denisovan fossils are very scarce," with only a few confirmed finds in East Asia, said study co-author Takumi Tsutaya at the Graduate University for Advanced Studies in Japan.

All of the full-time employees in the Centers for Disease Control and Prevention's Vessel Sanitation Program are now off the job, multiple officials tell CBS News, gutting the agency's ability to investigate outbreaks and conduct health inspections on cruise ships. A smaller group of 12 U.S. Public Health Service officers will remain.
