Excavations in Georgia reveal 1.8 million-year-old human tooth

VAN (AA): Georgian archeologists have discovered a 1.8 million-year-old tooth belonging to an early species of humankind.

The tooth was discovered near the village of Orozmani, around 100 kilometers (62 miles) southwest of the Georgian capital of Tbilisi, near Dmanisi, where human skulls dated 1.8 million years old were found in the late 1990s and early 2000s.

The Dmanisi finds were the oldest such discovery anywhere in the world outside Africa and one which changed scientists’ understanding of early human evolution and migration patterns.

The latest discovery at a site 20 kilometers away provides yet more evidence that the mountainous south Caucasus area was likely one of the first places early humans settled after migrating out of Africa, experts said.

“Orozmani, together with Dmanisi, represents the center of the oldest distribution of old humans – or early Homo – in the world outside Africa,” the National Research Center of Archaeology and Prehistory of Georgia said, announcing the discovery of the tooth on Thursday.

Giorgi Bidzinashvili, the scientific leader of the dig team, said he considers the tooth belonged to a “cousin” of Zezva and Mzia, the names given to two near-complete 1.8 million-year-old fossilized skulls found at Dmanisi.

“The implications, not just for this site, but for Georgia and the story of humans leaving Africa 1.8 million years ago are enormous,” said British archaeology student Jack Peart, who first found the tooth at Orozmani.

“It solidifies Georgia as a really important place for paleoanthropology and the human story in general,” he told Reuters.

The oldest Homo fossils anywhere in the world date to around 2.8 million years ago – a partial jaw discovered in modern-day Ethiopia.

Scientists believe early humans, a hunter-gatherer species named Homo erectus, likely started migrating out of Africa around 2 million years ago. Ancient tools dated to around 2.1 million years have been discovered in modern-day China, but the Georgian sites are home to the oldest remains of early humans yet recovered outside Africa.
