The Panda Ancestor
The scientific name for the panda's closest ancestor is agriarctos. It's also known as the giant short faced bear. The giant short faced bear is now extinct and has been for 10,000 years.
Fossil Evidence Of Panda Evolution
Panda's Today
Panda Evolution
Because the pandas eat so much bamboo, over millions of years they have evolved a psuedo thumb. This psuedo thumb is an enlargement of a bone on the side of their hand. This evolution has helped them to grasp bamboo much easier. It also helps so they reach inside of the bamboo and pull out the shoots.

They live in elevations of 1,200-3,400 meters. Pandas eat 12-16 hours every day. They eat up to 22 pounds of bamboo every day. 99% of a pandas diet is bamboo.
A way the two animals were compared was by the distal cusps in the premolars. They also compared the Agriarctos fossils to the Giant Pandas fossils and came to a conclusion that they were relatives.
This is a cladogram of the Giant Panda
The oldest panda fossil ever found(by Yuanmouenis) is thought to be 8.2 million years old.
