[Ancestors of cats and dogs] Extinct species Miakis

Animal

Few people know about the common ancestor of cats and dogs. That’s no wonder, they are animals that lived in ancient times and are now extinct. Miakis means “mother of animals” in Latin. They are said to be the ancestors of bears and raccoon dogs, and lived from the European continent to the North American continent about 65-48 million years ago. Of course, there are no pictures of them because they are animals from tens of millions of years ago.

habitat

Miakis lived from Europe to North America. As for information, they are classified as the same as cats and dogs and are said to have the same ancestor. Of course, it evolved a long time ago, so even if you search for it, you won’t find any information about its appearance or form back then.

Characteristics

Miakis is 30 cm long. It is said to have had a slender body, a long tail, and short legs, and was said to have resembled a weasel. The hind limbs are longer than the forelimbs and have claws at the ends. Miakis is said to have lived in trees, because of the presence of powerful predators on the ground. The strongest predator in those days was the Hyaenodon, a carnivorous beast with a maximum length of 3m and a weight of 500kg, so Miakis is said to have come to live in trees.

ecology

Miakis is said to have lived by preying on reptiles and birds. Life expectancy is said to be decades.

Dog

Chinodictis, which evolved from Miakis and lived 12 million years ago, evolved into an animal called Tomarctus, which looks like a wolf or a dog, and is said to be the ancestor of the canid family. After that, they came to be bred by humans, and now they are very active in various fields such as rescue dogs, service dogs, and police dogs.

Cat

It evolved from Miakis, and about 20 million years ago evolved into Pseudaerrus, which was good at agility and tree climbing, and then branched repeatedly. The Libyan wildcat, which branched off from other wildcat species about 130,000 years ago, is said to be the ancestor of the domestic cat.

Dog and cat separated

Miakis lived in trees, eating reptiles and bird eggs as food. However, the struggle for survival in the forest gradually unfolded, and Miakis’ residence was divided into the following two streets. Miakis, who moved from the forest to the grassland, evolved into a dog, and Miakis, who did not move to the grassland and remained in the forest, evolved into a cat.

Extinct species

Why did Miakis go extinct? No one knows the exact reason. It is speculated that in the process of evolution, it was absorbed into a new evolutionary system.
