Dong et al. elucidate grapevine evolution and domestication histories with 3,525 cultivated and wild accessions worldwide: in the Pleistocene, harsh climate drove the separation of wild grape ecotypes caused by continuous habitat fragmentation; then, domestication occurred concurrently about 11,000 years ago in Western Asia and the Caucasus to yield table and wine grapevines; the Western Asia domesticates dispersed into Europe with early farmers, introgressed with ancient wild western ecotypes, and subsequently diversified along human migration trails into muscat and unique western wine grape ancestries by the Late Neolithic.

Early Neolithic jar, circa 6000-5000 BC, from Khramis Didi-Gora in the Republic of Georgia. Note the probable grape cluster motives encircling the mouth of the vessel, and the small base, which would have been inadequate for a free-standing vessel. The latter feature suggests that the jar was once partly or wholly buried underground, like modern qvevris (Georgian, ‘large jars’). This specimen is nearly a meter (3.3 feet) tall and a meter (3.3 feet) broad, with a volume exceeding 80 gallons. Image credit: Mindia Jalabadze / National Museum of Georgia.
