1 Answer. Cats, dogs and bears all belong to the Carnivora clade of mammals, but they are not the only ones belonging to this clade. For instance, cats are more closely related to mongoose and hyenas than to dogs or bears, who in turn are more closely related to raccoons, weasels, and walruses.
Are Bears Related to Dogs
In brief, although bears and dogs share many characteristics, they are not directly related. Scientific classification and historical evidence can be used to determine whether or not particular animal breeds are related.
The scientific method of classifying animals according to particular traits is called taxonomic classification. We still use this system, which was developed in the eighteenth century by Carolus Linnaeus, to better understand the relationships between various animal species.
This system divides specific animal classifications into more general categories, up to the largest grouping, called a kingdom. When classifying an animal, factors such as behavior, habitat, diet, and physical characteristics are taken into account.
Among the family Canidae, which also includes wolves, coyotes, and foxes, are dogs in particular. Their long jaws, non-retractable claws, pointed ears, and less specialized teeth
However, given the differences in ear shape, thick coats, sturdy claws, and other characteristics, it is obvious that bears are not members of the dog family.
So which family are bears in? They are members of the Ursidae family, which is also made up of creatures like weasels, raccoons, and pandas. All members of this family have plantigrade feet, which means they walk on the entire bottom of their feet rather than just their toes, short snouts, and round ears.
Dogs and bears are not related by blood, but they are both classified as facultative carnivores. This is a subclass of animals in the Carnivora Order that consists of any organism that can subsist primarily—though not exclusively—on meat.
Most of the major obligatory carnivores, such as lions, tigers, and hyenas, are members of the Carnivora Order, as one might expect. But it also includes a number of other omnivores, or animals that consume both plants and meat. This includes bears, dogs, raccoons, and badgers.
Eventually, the broad-spectrum Carnivora Order split into the Feliformia and the Caniformia biological families. All feline species, including lions, tigers, and cheetahs, are included in the former category. Their claws are semi-retractile, and their faces are broad and short.
In the meantime, all of the canine-like creatures belong to the Caniformia family. This category also includes bears, weasels, and sea lions in addition to dogs, wolves, and foxes. It’s hardly surprising that they have a lot in common both physically and behaviorally given their grouping.
But it’s crucial to keep in mind that this is just an evolutionary coincidence. Even though they might be grouped together, that doesn’t always imply a close relationship.
The fact that dogs and bears have a common ancestor, the Miacids, is the closest evidence that suggests dogs and bears are related. These diminutive, omnivorous organisms existed between thirty and sixty million years ago.
From there, the Feliformia and the Caniformia families eventually split. Despite having similar ancestry, they have developed separately to become the unique species that they are today.
How closely related are dogs and bears? While bears and dogs don’t share a direct family lineage, they do both belong to what’s known as facultative carnivores. This is a subgroup of animals within the Carnivora Order that includes any creature that can survive on a diet that’s mostly, but not exclusively, meat.
- Panthera, or roaring cats, includes jaguars, lions, tigers, leopards, snow leopards, and clouded leopards.
- Acinonyx (the Cheetah)
- Felis (all other small cats)
