Experts Dated Oldest Modern Human Fossil in Eastern Africa to Over 230,000 Years Ago

Since the discovery of the remains called Omo I in Ethiopia in the late 1960s, scientists have been analyzing chemical fingerprints of volcanic ash layers discovered above and below the sediments in which the fossilized remains were located to date the Omo I remains correctly. Earlier attempts to date the fossils revealed they were less than 200,000 years old, but the current analysis suggests they must be older than a major volcanic explosion that took place 230,000 years ago.
