Recent findings at an archeological dig in the country of Georgia are calling into question long-held beliefs about human evolution. Skulls uncovered at Dmanisi, south of Russia, suggest that instead of emerging from Africa, modern humans may have evolved in Europe. The 1.8-million-year-old skulls resemble those of early ancestors of Homo erectus, suggesting that our very early ancestors travelled to Europe. There, they may have evolved into Homo erectus before journeying back to Africa, where they made the transition to Homo sapiens.
