Tamed 11,400 years ago, figs were likely first domesticated crop

ops without insect pollination and is prevented from falling off the tree, allowing it to become soft, sweet, and edible. However, because such figs do not produce seeds, they are a reproductive dead end unless humans interfere by planting shoots from the parthenocarpic trees.

"Once the parthenocarpic mutation occurred, humans must have recognized that the resulting fruits do not produce new trees, and fig tree cultivation became a common practice," Bar-Yosef says. "In this intentional act of planting a specific variant of fig tree, we can see the beginnings of agriculture. This edible fig would not have survived if not for human intervention."

Figs are very easily propagated: A piece of stem stuck in the ground will sprout roots and grow into a plant. No grafting or seeds are necessary. Bar-Yosef, Kislev, and Hartmann suggest that this ease of planting, along with improved taste resulting from minor mutations, may explain why figs were domesticated some five millennia before other fruit trees, such as the grape, olive, and date.

"The reported Gilgal figs, stored together with other vegetal staples such as wild barley, wild oat, and acorns, indicate that the subsistence strategy of these early Neolithic farmers was a mixed exploitation of wild plants and initial fig domestication," Bar-Yosef says. "Apparently, this kind of economy, a mixture of cultivation of wild plants, planting fig trees and gathering other plant foods in nature, was widely practiced during the second half of the 12th millennium before present throughout the Levant, the western wing of the Fertile Crescent."
