The archeologist Andrew Smith, discovered a skeleton in St
Helena´s baith in 2010, near the place where some human tracks from 117.000
years ago, appeared. Those prints were called Eva´s prints. That skeleton
belongs to a man that lived in southern Africa 2.330 years ago, and the finding
of it gives us more information about human´s origins and our common ancestor.
The mitocondrial or matern DNA extracted from a teeth and a
rib was analyzed and it has aported the
first proof of our origin: we all come from Africa (from a lineage that is,
presumably, extinct). Besides, it can be used to develop the human geneological
tree with all the branches derivated from a common mitocondrial Eva.
The genetic information found in those bones are the oldest
ones that diverged from the genetic profile made about some modern human
appeared 200000 years ago.
