Scientists Find the Oldest Human DNA in 400,000-Year-Old Fossil
The oldest DNA evidence yet of humans' biological history was discovered by scientists on Wednesday in Spain. The fossil found dates back about 400,000 years shattering a previous record of 100,000 years. The thigh bone initially seemed to belong to a forerunner of Neanderthals, but its DNA showed that it actually belonged to an enigmatic lineage of humans known as Denisovans. The only other remains with the same type of DNA were found in Siberia, 4,000 miles east of where the new DNA was found. Scientists are now rethinking human evolution and considering the possibility of unknown extinct human populations that may have interbred, swapping DNA. Only time will tell.
