How Pandas Became Vegetarian Decoded After Discovery Of Fossils In China

The fossils belong to the now-extinct ancient relative of the panda called an Ailurarcto that lived in China six to eight million years ago.

The discovery of panda fossils in China has helped researchers solve the mystery of how the giant species developed a "false thumb" and became the only dedicated vegetarian in the bear family.

Fossils dating back about six million years found in southwest China's Yunnan province included a greatly enlarged wrist bone called a radial sesamoid.

It is the oldest known evidence of the modern giant panda's false thumb that allows it to grip and break heavy bamboo stems, scientists wrote on a research paper published in the latest edition of the Scientific Reports.
