You may have thought that dogs would be a little closer to humans on the evolutionary scale, but it turns out that cats actually have 90.2% of the DNA in common with us! You read that right! Cats are genetically surprisingly closer to us than dogs, who share about 84% of the genes with us (Pontius et al, 2007).
Lynxes, lions and cheetahs are the closest relatives to our furry companions, the domesticated cat. Outside of this family, there are roughly 90 additional species that makeup Feliformia, a suborder of “cat-like” carnivorans, which includes mongooses, civets and four species of hyena.
Cats are closer genetically to lions than dogs are to wolves. ABC News' Dan Harris helps to clear up misconceptions about our feline friends. — -- The family cat may sit on your lap for hours, purring in domestic bliss as it savors human companionship, but underneath that friendly fur beats the heart of a lion.
By taxonomy, hyenas are closer to cats than dogs. Hyenas are part of the Order Carnivora together with cats and dogs, but hyenas and cat are part of the Suborder Feliformia. A few genetic analysis have show that cats and hyenas share a more recent commune ancestor and therefore they are closer related.
Hyenas and lions cover the same ground, hunt the same prey, and scavenge the same remains of animals. Consequently they steal food from each other, chase each other, and even kill each other's young. 3. Should humans/conservationists intervene to reduce the conflict between lions and hyenas?
Lions and Other Beasts Fear Hyenas
What causes such fear in many animals, including the lions, is that hyenas often fight in packs. In an aggressive group attack, they outnumber the lions by a large margin and can shred them to pieces.
Bears are caniforms too, and are more closely related to dogs than cats are.
Scientists categorize big cats based on two specific qualities: they belong to the genus Panthera and have a special two-piece hyoid bone in their throat that allows them to roar. This limits the big cat club to just lions, tigers, leopards, and jaguars.
Wild cats get tamed
The cuddly domesticated house cats we love so much today are in fact descendants of lions and tigers, who are successors of early carnivores known as miacids. From here modern wild cats evolved into three key species – the European wild cat, the African wild cat and the Asiatic desert cat.
While our domestic cats and tigers shared a common ancestor around 10.8 million years ago they in fact share 95.6% of their DNA!
Cats are very territorial, much more so than dogs. Territorial aggression occurs when a cat feels that his territory has been invaded by an intruder. Depending on where your cat spends his time, he may view your whole neighborhood as his territory. Female cats can be just as territorial as males.
Hyenas are not members of the dog or cat families. Instead, they are so unique that they have a family all their own, Hyaenidae. There are four members of the Hyaenidae family: the striped hyena, the “giggly” spotted hyena, the brown hyena, and the aardwolf (it's a hyena, not a wolf).
So it seems the cat family evolved first! However, it's a different story when it comes to when humans domesticated cats and dogs. This is hard to find out about, but a burial of a man alongside an 8 month old cat is the oldest known evidence of cat domestication so far, at 9500 years old.
Spotted hyenas are more closely related to cats than dogs, despite their dog-like appearance. Their closest relatives are actually mongooses and civets. Unlike all other carnivores, spotted hyenas have a complex social system where animals live in female-dominated clans of up to 90 individuals.
Our feline friends share 90% of homologous genes with us, with dogs it is 82%, 80% with cows, 69% with rats and 67% with mice [1]. Human and chimpanzee DNA is so similar because the two species are so closely related.
Bears usually run from a dog because most bears have learned to associate dogs with people. However, a dog off leash may chase and harass the bear causing the bear to get angry and chase the dog. When dogs get scared they may run to their owner.
Based on the number of neurons found, they speculated that dogs have roughly the same intelligence as raccoons and lions, while domestic cats have comparable intelligence to bears. For comparison, humans have by far the highest number of neurons in our cerebral cortexes—as many as 16 billion per person.
Cats and dogs are colour blind
To see in full colour as we know it, humans use three cones – red, blue and green. However cats and dogs only have blue and green cones. This means they have a much more muted perception of colour, which is akin to colour blindness in humans.
The tiger shares 95.6 percent of its genome with the domestic cat, from which it diverged about 10.8 million years ago, the comparison showed. In addition, several genes were altered in metabolic pathways associated with protein digestion and metabolism, or how the body uses fuel like food to power cells.
In most cases, cats will purr when they are in a relaxed environment, sending out waves of calmness. This may also occur when you stroke them, and if this is the case, your feline friend is feeling happy or sociable. However, cats purr to communicate other emotions and needs, too.
Lions have few predators to fear other than humans. A very young or sickly lion might fall prey to hyenas. Cubs may be attacked and eaten by adult male lions. Lions are most threatened by humans who hunt them and encroach on their habitat. Lions do not selectively hunt humans and do not often attack humans.
Do lions have predators? No predators hunt lions to eat them; however, they do have a few natural enemies, such as hyenas and cheetahs. Hyenas compete with lions for food and often try to steal their kills.
While it may look shocking, it is not unheard of for groups of hyenas to take down lions – most often cubs or older individuals.
