Peaches used to be small, cherry-like fruits with little flesh. They were first domesticated around - 4,000 B.C. by the ancient Chinese and tasted earthy and slightly salty, "like a lentil". They had a waxy skin and the flesh represented 64% of the fruit.

But after thousands of years of farmers selectively breeding them, peaches are now 64 times larger, 27 percent juicier, and 4 percent sweeter. Their skin is now soft and edible skin and represents 90% of the fruit.
