Researchers have now discovered that the kiwi fruit we’re eating today, has as much vitamin C as an orange.
Sciencedaily.com reports that the “extra boost in vitamin C production is the result of the kiwifruit's ancestors' spontaneously duplicating their DNA in two separate evolutionary events approximately 50-57 million and 18-20 million years ago.”
"Polyploidy is an abrupt evolutionary event that produces thousands of extra copies of genes overnight," says senior author Xiyin Wang, an agricultural plant scientist at the North China University of Science and Technology.

"These extra copies may greatly elevate the robustness of the plant, providing opportunities for natural selection to prune and rewire its biological system over time."
The report also points out that kiwis, coffee, and grapes “share a common ancestor and thus share large swaths of genetic information,” so soon we might get coffee and grapes that has the recommended daily dose of vitamin C.
