Unlike giant pandas who currently live in mountains from the southwest of China and they eat exclusively from bamboo, your ancestors already missing they probably had diet more diverse, similar to those of others mammals, according to a study published today (January 31, 2019).

"It is generally accepted (the belief) that giant pandas are fed exclusively to bamboo in the past two million years, but our results they proved to be the opposite, "explained Fouwe Wei of the Chinese Academy of Sciences and author of the work published in the journal Current biology.

To carry out his research, Fulen and his team analyzed it isotopes on bone collagen of modern pandas and fossils of 12 ancient pandas collected from seven archaeological sites in southern and southwestern China.

A comparison of the data showed that the isotopes of one and the other are different, which suggests that differences in their eating habits.

This means that the ancient giant pandas had diverse diet, similar to others mammals who lived beside him, and probably are not fed only with bamboo, according to researchers.

In addition, the authors of this study believe that the eating habits of the giant pandas evolved in two phases.

First they went from being omnivores to eat plants, and then, in the second phase, they began to feed exclusively on bamboo, for which they have a special finger that allows them to better understand their stems, leaves and buds.
