Scientists find out why giant pandas eat bamboo rather than meat

Chinese scientistshave made progress in revealing more details of giant pandas' feeding habits and why they eat bamboo rather than meat although their teeth and the construction of the digestive tube are similar to carnivores.

Despite having physical characteristics more suitable for eating bamboos, including when compared alongside other carnivores as well as a relatively larger head, pandas cannot absorb energy by digesting cellulose as well as herbivores.

However, they do better in digesting starch than other carnivores, and they usually choose the starchiest part of bamboo trees for consumption, according to a recent survey conducted by Zhang Wenping, a researcher at the Chengdu Research Base of Giant Panda Breeding.

By analyzing fecal matter from giant pandas, researchers found that giant pandas can only obtain energy from starch, hemicelluloses, and pectin in bamboos. The reason that giant pandas is that bamboos, widely distributed in the wild, are easy forthem to obtain, and they contain more starch than other woody plants.

Also, giant pandas consume little energy each day, indicating that their relatively heavy weight can be maintained by just feeding on bamboo.

The pandas have evolved through more than in which they have fed on bamboo. Previous gene sequencing research also shows that the creature lost in the process of evolution and, therefore, started to eat bamboo.
