A DOMESTICATED GRAPEVINES MIGRATE WITH HUMANS People domesticated vines independently in two regions, the Caucasus and western Asia, starting about 10,500 years ago and transported vines as they relocated over millennia (arrows). A large international group of researchers collected and analyzed 2,503 unique vines from domesticated table and wine grapes and 1,022 wild grapevines. by extracting DNA from the vines and determining the patterns of genetic variations among them, they found some surprises. Wild vines separate into two geographic regions Domesticated wine vines migrate with humans Cultivated vines diversify genetically WILD GRAPES SEPARATE Cold, dry, ice-age climates gradually killed grapevines in the Balkans between 200,00C and 20,000 years ago, leaving western and eastern groups of vines that evolved into distinct genetic lines.
