Archaeologists at the Omo Kibish site in Ethiopia, where Richard Leakey found human fossil remains in 1967, used volcanic ash analysis to show their true age.
Volcanic ash left over from a huge ancient eruption has helped scientists determine that important early Homo sapiens fossils found in Ethiopia in 1967 are older than previously believed,.
The new findings conform with the most recent scientific models of human evolution placing the emergence of Homo sapiens sometime between 3,50,000 to 2,00,000 years ago.
