Humans Gathered Grapes Long Before They Cultivated Them

By Diane Nelson

About 22,000 years ago, as the ice sheets that consumed much of North America and Europe began retreating, humans started to eat a fruit that today brings joy to millions of wine drinkers around the world: grapes.

People have been making wine from grapes for at least 8,000 years, but genetic evidence shows that humans influenced grape vines long before that (Gregory Urquiaga/UC Davis).
