Some of us think it's the cutest, others think it's the worst… I think science has finally settled the debate with a new study about the panda; and it turns out, they are terrible at life. Here's what you probably know about Giant Pandas already: they are solitary tree-climbing black-and-white mountain bears that only eat bamboo and are notoriously difficult to breed in zoos. All of that is true, but new research from the American Society of Microbiology studied the gut bacteria of the giant panda and found they're NOT GOOD AT DIGESTING BAMBOO. WHICH IS THE ONLY THING THEY'LL EAT. According to their findings, the giant panda's microbiota are horribly adapted for the diet that they eat. Which is just. *i mean* I just need a minute here. Guys. Giant Pandas eat bamboo for 14 hours every day. It's one of the fastest growing plants in the world[1], some species can grow a meter a day; which is good because pandas consume 27.5 pounds (12.5kg) of it daily, but STILL CAN'T DIGEST IT. They only process about 17 percent of the stuff they shove in their maw! This is an incredibly sad and real illustration of evolutions lags. Looking at what bacteria the panda DOES have, reveals the evolutionary history of our favorite black and white bear. Pandas began to exclusively eat bamboo around two million years ago, but even so, their gut flora were essentially the same as their carnivorous and omnivorous cousins! Surprisingly, they have not evolved some of the basic bacteria to break down the plant fibers; and YET EAT PLANTS. What the hell evolution? Dick move. So it seems as if it's supposed to eat meat, based on the bacteria living inside its gastrointestinal tract. The reason why it doesn’t might be answered by a study in PLOS One. The study looked at the genes of the giant panda, and found 4.2 million years ago, the giant panda's T1R1 gene mutated, causing them to lose ability to taste umami -- the deliciousness that comes from meats like bacon. Their appetite-reward system was forever altered, and this mutated species lost its taste for meat, literally! Okay, that's a little hyperbolic, pandas DO eat the occasional small rodent, or deer fawn. But scientists believe because of the loss of umami, their herbivorous diet was further reinforced. Funnily enough, herbivores like cows and horses DO carry the T1R1 gene which allows for umami… Scientists are puzzled to say the least. To add to all this biological dissonance, are the well-documented problems with panda breeding. Females only ovulate once a year, for only a couple of days! If the female doesn't meet a male -- they're really solitary remember -- they don't birth any cubs that year. But if they do, the newborn is 1/900th the size of its mother; it's seriously tiny and blind, and it requires feeding every two hours when it cries -- similar to a human baby. Eventually they grow and mature, gaining black and white hair that scientists still don't understand and three years later will strike out on its own -- THIS IS SERIOUSLY THE WORST SYSTEM FOR BEING AN ANIMAL. Look. I don't want them to go extinct, but it sure sounds like the panda just doesn't want to panda, doesn't it? But let’s not put the blame entirely on them. Thanks to humans destroying the panda habitat, there are only about 1,000 left in the wild, and maybe 100 in zoos; we're learning a lot about them! But man, the more I learn, the more I just shake my head. Do you love pandas? Not just the red ones, they're the cutest.
