It gives absolutely no evidence that pandas have evolved from non-pandas. And although some pandas will eat meat, they prefer bamboo, fruit and plants. Yet we find there is no evidence their ancestors were anything but vegetarian pandas. In fact, zoologists still can't agree after more than a century on what pandas could have evolved from. The red panda's sharp claws and vicious bite are not leftover traits from a time when its ancestors attacked and defended themselves from other animals.
Pandas have no enemies other than man.
Their claws simply help them climb trees easily. And their strong jaws and teeth are needed to snap and crunch their huge daily meals of bamboo. These traits don't show us evolution.
