Scientists claim to have unravelled the oldest DNA ever retrieved from a Homo sapiens bone, a feat that sheds light on modern humans' colonisation of the planet. Teased out of collagen in the ancient bone, the genome contains traces from Neanderthals -- a cousin species who lived in Eurasia alongside H. sapiens before mysteriously disappearing. Previous research has found that Neanderthals and H. sapiens interbred, leaving a tiny Neanderthal imprint of just about two percent in humans today, except for Africans. Dating when Neanderthals and H. sapiens interbred would also indicate when H. sapiens embarked on a key phase of this trek -- the push out of Eurasia and into South and later Southeast Asia.
