Why are dogs more loyal to humans than cats? How do cats and dogs recognize their owners

Many people like to keep pets, and the most common ones are cats and dogs. In most people's ideas, dogs seem to be more relatives and more loyal than cats. Why are dogs more loyal to humans than cats? Do you know why? How do dogs and cats recognize their owners? Let's learn about their owners with Xiaobian.

Dogs became human pets earlier than cats

Dogs are the first animals that human beings began to domesticate, and it happened before the agricultural revolution. Although experts have different opinions on the exact age, archaeological evidence shows that domestic dogs were born about 15000 years ago, and their actual time of joining human life may be pushed forward by thousands of years. In addition to hunting and fighting, dogs can also serve as an alarm system to warn of wild animals or human invasion.

Over time, people and dogs have evolved together and can communicate well with each other. The dog that can best meet human needs and care for human emotions can get more care and food, so it is easier to survive. At the same time, dogs have learned how to please people and meet their needs. After 15, 000 years of being together, the understanding and emotion between man and dog is far more than that between man and other animals. In some cases, even dead dogs can be buried.

Let's look at the domestication of cats. When was the cat domesticated? About 6000 years ago, it began in ancient Egypt in the Middle East. The young of African wildcat is easy to be domesticated. It is generally believed that it may be the main ancestor of domestic cats. At that time, the living conditions of human beings had been greatly improved and improved. Human beings had entered the farming society, and their survival materials and food resources were not so deficient. They could not only maintain their lives, but also had surplus stocks. So why domesticate cats? Because mice, when humans have surplus food, have to fight with rats, and cats are the best weapons.

Why are dogs more loyal to humans than cats

It is the nature of dogs to be loyal to humans. Edward Wilson, a professor of biology at Harvard University, believes that the courage and resilience shown by today's dogs in protecting their owners from harm stems from the unity of their ancestors' social life.

The gregarious dog has a strong collective instinct, so the dog is accustomed to collective action. It will obey a stronger person than himself or the leader of the team. Dogs have a keen sense of hearing and smell, and can find prey as early as possible, or chase or bite prey. In the process of hunting, they are very helpful to human beings. Since then, humans have been actively raising dogs, choosing dogs that are more loyal to their owners, and these dogs will have a better chance to breed.

Later, in the farming society, people who lived a settled life kept storing food and gradually formed large tribes. Later, in order to get more fertile land, there was competition among tribes. Therefore, they are not only wary of animals, but also wary of human beings. In this process, the dog's vigilance to strangers and the ability to tell people that there are abnormal things through barking also play a great role. Therefore, from the dog watching things to the hound and shepherd dog, and then to the process of watching the dog, the relationship between human and dog is more and more profound.

However, in the cat's view, rats are caught by themselves and have nothing to do with human beings, so the food they get is due to their own efforts. They just establish a mutually beneficial relationship with human beings. Therefore, there is no need to be so loyal to human beings, let alone flatter them.

How do dogs and cats recognize their owners

People who have dogs will have this feeling: when you go out to go home, it will quickly wag its tail and pounce on its owner, the scene is warm, so how does the dog identify its owner?

The first is smell. Dogs have a lot of wrinkles in their noses, which are similar to humans, but they have much more folds than humans, spreading out about four times the size of humans. And the olfactory cells on the folds are also densely packed. There are 5 million olfactory cells in humans and 125 million in dogs. Just comparing the number of olfactory cells in the nasal cavity, we can know how powerful a dog's nose is. Dogs not only have a keen sense of smell, but also have a deep memory. They can remember a lot of smells, especially those of their owners. No matter how long it takes, they will never forget.

The second thing that can tell the owner is listening. The hearing of dogs is 16 times higher than that of humans, and the sense of hearing is very strong. Even if you are far away, the dog can recognize your voice immediately.

Cats are very similar to dogs. Cats also have a good sense of smell. For example, a cat can easily smell a mouse running for a long time, and then follow the smell to catch the mouse. The taste of the owner is remembered by the cat as well as the dog for a long time.

The cat's hearing is also excellent. You take a small step towards it quietly, and it can hear it, and instantly alert. Cats are also better at locating sounds than humans. Their two ears, like radar antennas, can rotate in the direction of sound. Whenever the owner calls the cat's name, the cat can tell whether it is its owner or not. If so, it will even call out to respond.

Who is better, cat or dog

The average brain capacity of a dog is 64 grams, while that of a cat is only 25 grams. However, the average weight of a dog is much heavier than that of a cat. Another way to more accurately measure the brain's intelligence is to look at the brain's ability to process information, that is, the number of cortical neurons. Cats are far better than dogs in this respect, with 300 million neurons in the cat's cortex, compared with 160 million in dogs.

Dogs can find food based on human actions, such as extending fingers and nodding their heads. Even chimpanzees with high IQ can't do this. The cognitive ability of cat is similar to that of dog, and its behavior is similar to that of dog. But cats are not as obedient as dogs, so it's hard to get them to carry out orders. If the food is hidden, the dog is more likely to look for help from its owner, while the cat tries its best to find it on its own, though in vain.
