How have pandas changed over time?

Answer 1

The panda's thumb has evolved-- twice. It has turned into an omnivore (it doesn't only eat bamboo, but also small insects) instead of an carnivore like its ancestors. And there is a legend in China. Here it is:

Long ago pandas were pure white. Chinese legend tells how the panda got its black and white coat. The ancient tale tells of a young girl who gave her life to save a snowy white panda cub. The pandas were very sad and rubbed black ashes on their legs as a sign of mourning. They wiped their eyes, hugged each other and covered their ears with their paws. Wherever they touched themselves the ashes stained their fur black.

So, yea. Hope this helps :)
