People say wolves are like lonely warriors who never surrender, but in fact, they are the first animals domesticated by humans. Scientists believe that all domestic dogs in the world evolved from wolves approximately 10,000 years ago from East Asia

200,000 years ago, the most ferocious predators in the food chain had three: Titan bird, saber-toothed tiger and wolf. With the passage of time, other top predators disappeared, only the wolf survived, and once became the highest-end ruler of the food chain. Until the appearance of humans, it was replaced

Wolf packs have had social systems since their emergence, they formed in the form of core families, including a pair of mates and their offspring, sometimes also adopting orphaned wolf cubs. When wolves start to howl, although sometimes it looks like a bow and arrow, in fact their relationship is quite harmonious

Wolf packs have a very strict hierarchical system. A wolf pack's number is normally about 7, so-called seven wolves, and some wolf packs have exceeded 30. Wolf packs do not overlap with other packs, and both sides strictly do not cross the border, usually announcing the range with howls

Wolves are social animals, but they only have one companion in their lifetime. Once two wolves choose to be together, they will stay together for life

When wolves run quickly to catch prey, they use their toe running, which will help them stop and quickly turn, and better protect their paw pads

Wolves have two hundred million olfactory cells, about 40 times that of humans, they can smell animals one mile away

Wolves have strong jaw strength, about 1500 pounds per square inch, while dogs only have 750 pounds. They have 42 strong teeth, used to pierce, cut and crush meat and bones

Wolves' pregnancy is about 63 days, cubs are not heard or seen when they are born, they have no self-defense ability, their eyes are blue and will not turn to normal yellow until eight months

The emergence of the wolf king in the wolf pack is extremely cruel, a large male wolf can only defeat all other adult male wolves in the wolf pack to become the wolf king. The wolf king can have the best nest, priority mating rights and priority to choose food

Some wolves suffer from rabies, but they are not carriers, usually infected with the disease from some prey (raccoon and fox)

Wolves' food is diverse, when hunting, each wolf in the wolf pack has a clear division of labor, expanding the wolf pack tactics, and every time they return with a full load
