Prehistoric Caucasus
The Caucasus region, on the gateway between Southwest Asia and Europe, plays a pivotal role in the peopling of Eurasia, possibly as early as during the Homo erectus expansion to Eurasia, in the Upper Paleolithic peopling of Europe, and again in the re-peopling Mesolithic Europe following the Last Glacial Maximum, and in the expansion associated with the Neolithic Revolution. == Lower to Middle Paleolithic == Dmanisi skull 5, found in Dmanisi, Georgia, is among the earliest Homo erectus fossils, dated to 1.8 Ma.
