To be honest, guys, it's kind of shitty, but he's right.
Pandas are really bad at evolution. If anything, we should be embracing them as solid proof against intelligent design - they're a carnivorous species of bear that survives primarily on a hard to digest plant that provides virtually no nutrition. They spend 90+% of their waking time eating, or looking for patches of bamboo to eat. They have to eat 30 pounds of bamboo a day to survive.
Because all they eat (99%) is bamboo, which they can't digest properly because they're carnivores, and can't digest easily because the plants are so fibrous, they have virtually no energy which makes them incredibly slow and insures that they have virtually no dexterity. Because of this Pandas stay away from inclines and do not climb.
They're anti-social animals who can't coexist around other Pandas, or most other animals, so they rarely breed and will only mate with pandas that match some strange panda criteria - because they're so picky most Pandas never breed and those that do breed rarely and in small numbers.
So why haven't Pandas died out yet? They're really big carnivores. That's the only thing that has really saved them. Their only evolutionary ace. Carnivores don't often hunt and eat other carnivores, and there's not many predators that can hunt in that size category. That's where we come in. Hate to say it guys, but if we were ever given an evolutionary place in the world, our evolutionary place was to make sure that the flawed genetics of the Panda don't continue into further generations and species. We are their only real natural predator, and failure is unfortunately their destiny.
I know Pandas are very cute animals. It's very sad that Pandas have to die out. But come on, guys - this is evolution. Evolution, unfortunately, does not always evolve viable species.
