When compared side by side, dogs and bears look eerily similar. However, this is not true of all dogs. Some of the larger and hairier varieties, though, are called “bears” for obvious reasons. Furthermore, there are numerous shared anatomical features between canines and bears. Do bears and dogs share any sort of connection, or is this all a coincidence?
Is there a Strong Connection between Bears and Dogs?
The short answer is “not here.” Similarly emphatic. Even though bears and dogs look so similar to one another, they are quite far from one another on the evolutionary tree. Dogs, wolves, foxes, and jackals are all members of the Canidae family.
However, bears, such as the panda bear, belong to the family Ursidae. Since bears and dogs aren’t related, there have been many cases of households adopting bear cubs thinking they were dogs.
Why do Dogs and Bears look so much alike?
Causes include natural selection incentives and simple evolutionary routes. Both species needed sturdy furs, paws, claws, canine teeth, etc. to survive. This is not to say that their lifestyles are identical, of course.
Although both dogs and bears are omnivores (they may eat both meat and vegetables), bears are often much more tolerant of a vegetarian diet than dogs are. Bears today still eat almost exclusively fruit and foliage, yet they still have their characteristic huge canine teeth, pointed claws, and muscly bodies.
What do Bears and Dogs have as their Most Recent Common Ancestor?
Dogs and bears share a similar ancestor that lived 42 million years ago, according to scientific research. A large or “bear-like” ancestor was not present. However, these were examples of the now-extinct family Miacidae. They were little and lived in the trees; their tails were lengthy. Smaller, carnassial teeth indicated a diet high in meat.
Although they looked nothing like modern bears or dogs, scientists believe the Miacidae family to be the true origin of the Carnivora Order. The gradual divergence of Miacidae species led scientists to categorize them all under the same Order.
