Pandas have six fingers because of a mutation in their genes. There are two primary theories as to why pandas have six digits on both the front and hind feet, rather than the usual mammalian five digits.
The first theory suggests that the sixth digit is an evolutionary adaptation based on the diet of pandas. This extra digit allows pandas to better support the stems of bamboo, which makes up 99% of their diet.
The second theory proposes that the mutation originated in an ancient ancestor, and has been retained in the panda genome by genetic drift. This means that the gene responsible for the sixth digit has persisted due to chance and is not necessarily beneficial to the panda, which is why only some species of bear display the same trait.
Regardless of the original cause of the mutation, it seems that the mutation has been advantageous for the giant panda and has been beneficial to their survival.

What are 5 interesting facts about pandas?
1. Pandas are native to southwestern China, and their scientific name is Ailuropoda melanoleuca.
2. They can grow to between 4 and 6 feet in length, with a shoulder height of around 2 to 3 feet.
3. These mammals eat almost exclusively bamboo, which makes up 99% of their diet.
4. While they appear cute, they are top predators and are skilled fighters – they have even been observed standing on their hind legs to drive predators away.
5. Pandas are a critically endangered species, and there are an estimated 1,864 adult pandas living in the wild, as of 2018. Conservation efforts are actively underway in an attempt to save this species.
How many hearts does an panda have?
A panda does not have multiple hearts or even an extra heart like some other animals. Instead, a panda just has one single heart like every other mammal. The heart of a panda is relatively large when compared to the size and weight of the animal, which helps it to maintain its metabolic and circulatory functions, as well as its core body temperature.
The heart of a panda beats to the same rhythm as a human heart, but the rate varies according to the panda’s activity and stress level. Additionally, the heart is protected by thick layers of fat, which helps keep it safe.
Which animal has 32 hearts?
The octopus is the animal that has 32 hearts. An octopus has three hearts that each pump blue-green oxygenated blood to the organs and three separate hearts that pump colorless deoxygenated blood to the gills.
This creates a closed circulatory system which the octopus can use to quickly and efficiently distribute oxygen and nutrients to its eight arms and other organs. Each of the eight arms also possess their own hearts, which are designed to pump blood to the arm itself.
This complex cardiovascular system allows an octopus to quickly and effectively catch prey, swim, and perform other life-sustaining activities.
Is there an animal with 4 hearts?
No, there is not an animal with four hearts. This is because, generally speaking, the majority of animals have one heart. However, there are a few species that have two hearts, such as the octopus. This is because octopus have a circulatory system that is divided into two parts, each with its own heart.
Other multi-hearted species include the squid, which has three hearts, and the horseshoe crab which has nine hearts. It is also important to note that humans and other mammals have two separate circulatory systems.
This means that each system has its own heart. So technically, you could say these animals have four hearts, but they are two separate systems rather than one single heart.
Has a panda got 4 legs?
No, pandas have not got 4 legs. Pandas have 2 front legs and 2 slightly shorter back legs that enable them to sit upright. The hind legs are longer than the front legs, allowing the panda to climb homeothermic rocks and trees.
Pandas have 5 toes on each front paw, but 4 toes on each hind paw. The panda has a ‘thumb’ on each paw which is an elongated bone that gives the animal a firmer grip when climbing trees. The sole of the foot is slightly concave which helps them to climb more efficiently.
Pandas are surprisingly fast and can reach speeds of up to 25 miles per hour when they are in flight.
Can pandas cry tears?
No, pandas cannot cry tears. A common misconception is that pandas cry when they are feeling sad. However, this is not the case. Pandas, like other animals, are unable to produce tears. In fact, pandas don’t even have tear ducts.
Though they may appear to be sad due to the distinctive facial expression they make, the truth is that they are simply unable to produce tears.
What do pandas use their sixth finger for?
Pandas have a sixth digit, known as the pseudothumb, located on their front paws. This digit is an enlarged version of an extra-flexible wristbone, known as the radial sesamoid, which they use to help rope and grip food, such as bamboo shoots, as well as to manipulate objects, such as scratching their head or rubbing a sore spot.
They also use this digit to allow them to hold onto branches and cling to thick tree bark. While they sometimes walk or climb trees with all five fingers, they are able to rely upon their sixth finger when they want to transfer their weight during certain balancing acts.
Additionally, small cup-shaped pieces of fur around the sixth finger act as a cushion, allowing pandas to grip onto slippery surfaces, such as tree trunks.
Can you hug a giant panda?
Unfortunately, you cannot hug a giant panda due to their endangered status and the fact that they are wild animals. Giant pandas live in the temperate forests of southwest China and are at risk of extinction due to several environmental factors.
To protect the species, humans are not allowed to touch or interact with them directly. Furthermore, human interaction can cause the pandas to become too accustomed to humans and not be able to survive in the wild if they’re released back into their natural habitat.
Conservation programmes that focus on protecting and breeding pandas in captivity are continually being developed to ensure their survival, so we can admire them from a distance.
How did the panda’s thumb evolve twice?
The panda’s thumb is an impressive example of convergent evolution, a process by which different species independently evolve similar features to adapt to similar environments. While many mammals have a thumb-like bone, the panda’s thumb evolved twice — first when the first panda ancestors adapted to a life of climbing and evolved the bone, then again when they developed the specialized bone structure that the modern panda has today.
Initially, the giant panda saw its thumb evolve from a bone found in its wrist. This bone acted as a primitive thumb, allowing the panda to anchor itself to surfaces as it climbed. But over time, the panda evolved a more specialized thumb structure.
Adapting to the difficult mountainous terrain in which the pandas lived, their thumbs became more mobile and longer in length so that they could better grip and manipulate bamboo — their main source of food.
The panda’s thumb is an impressive example of evolutionary innovation. By evolving twice, it equipped the panda with the tools necessary to survive in a unique and challenging environment.
