Did humans evolve in Eurasia?

The conventional view of human evolution and how early man colonised the world has been thrown into doubt by a series of stunning palaeontological discoveries suggesting that Africa was not the sole cradle of humankind. Scientists have found a handful of ancient human skulls at an archaeological site two hours from the Georgian capital, Tbilisi, that suggest a Eurasian chapter in the long evolutionary story of man. The skulls, jawbones and fragments of limb bones suggest that our ancient human ancestors migrated out of Africa far earlier than previously thought and spent a long evolutionary interlude in Eurasia – before moving back into Africa to complete the story of man. Experts believe fossilised bones unearthed at the medieval village of Dmanisi in the foothills of the Caucuses, and dated to about 1.8 million years ago, are the oldest indisputable remains of humans discovered outside of Africa.
