Ancient peach stones reveal domestication history | Past Horizons

Ancient peach stones reveal domestication history | Past Horizons | Kiosque du monde : A la une | Scoop.it

Research has revealed that today's domesticated peaches can trace their ancestry back at least 7,500 years ago to the lower Yangtze River Valley in Southern China...

Peach stones are well represented at archaeological sites in the Yangtze valley, so they compared the size and structure of the stones from six sites that spanned a period of roughly 5,000 years. By comparing the size of the stones from each site, they were able to discern peaches growing significantly larger over time in the Yangtze valley, demonstrating that domestication was taking place. The first peach stones in China most similar to modern cultivated forms are from the Liangzhu culture, which flourished 4,300 to 5300 years ago.

Positive selection

“We’re suggesting that very early on, people understood grafting and vegetative reproduction, because it sped up selection,” Crawford said. “They had to have been doing such work, because seeds have a lot of genetic variability, and you don’t know if a seed will produce the same fruit as the tree that produced it. It’s a gamble. If they simply started grafting, it would guarantee the orchard would have the peaches they wanted.”

Crawford and his colleagues think that it took about 3,000 years before the domesticated peach resembled the fruit we know today.

“The peaches we eat today didn’t grow in the wild,” Crawford added. “Generation after generation kept selecting the peaches they enjoyed. The product went from thinly fleshed, very small fruit to what we have today. Peaches produce fruit over an extended season today but in the wild they have a short season. People must have selected not only for taste and fruit size, but for production time too.”

Discovering more about the origins of domesticated peaches tells us more about our human ancestors, too, Crawford noted.

Crops such as domesticated peaches indicate that early people weren’t passive in dealing with the environment. Not only did they understand grain production, but the woodlands and certain trees were being manipulated early on.

“There is a general sense that people in the past were not as smart as we are,” said Crawford. “The reality is that they were modern humans with the brain capacity and talents that we have now.

“People have been changing the environment to suit their needs for a very long time, and the domestication of peaches helps us understand this.”
