* Scientist reconstructed the mitochondrial genome from two grams of bone
* They found early humans shared a common ancestor with the Denisovans
* This was suprising as early humans were thought to share a common ancestor with Neanderthals due to similar skeletal features
The world's oldest human DNA has been recovered from the thigh bone of an ancestor that walked the Earth 400,000 years ago.
It belonged to a hominin, or early human, known as Homo heidelbergensis and provides a new vital piece of the jigsaw in the story of evolution.
Using a technique for retrieving and sequencing highly degraded ancient DNA, scientists were able to reconstruct the almost complete mitochondrial (mt) genome from just two grams of bone powder.
Oldest DNA Leads To Evolution Questions. A 400,000-year-old thigh bone found in Spain surprises scientists with its genetic links, which they cannot yet explain.
