Question 1: What is the ancestor of dogs 1. The origin of dogs has been an interesting and controversial issue for many years. Although zoologists all over the world have done a lot of research and textual research, because their domestication date is prehistoric, the relevant information and opinions are not perfect. Some people think that the only ancestor of dogs is wolves or jackals, and even some little-known extinct breeds. But the most widely accepted view is that dogs have multiple ancestors, including extinct and existing. Charles Darwin strongly agreed with the multi-ancestor theory that domestic dogs are descended from at least two kinds of wolves. But he cautiously added: "We may never know the exact origin of domestic dogs. Paleontology has not yet figured out this problem, on the one hand, because the skulls of extinct animals are very similar to those of existing wolves and jackals, and on the other hand, because the skulls of domestic dog breeds are very similar. " Since Darwin's time, Richard and Alice Fiennes have had the most extensive and practical discussion about the ancestors of dogs. In their book The Wild History of Dogs, they think that early dogs, such as Australian wild dogs, Eskimo dogs, African hounds and Indian hybrid wild dogs, are closely related to wild canids, and they can't be separated in any case. The modern experiment of taming wolves in the former Soviet Union shows that although wolves are rarely as docile and vigilant as dogs, they are still relatively afraid of people, not all of them are fierce. On the Olympic Island in Washington, USA, there is a pasture for raising herds. These wolves can get along well and cooperate with their masters. There are many real reports all over the world about the abandoned baby adopted by the mother wolf in the wilderness and fed as "wolf children".1In May, 972, bhaskar, an abandoned baby raised by wild wolves, was found in the Indian forest. He actually spent several spring and autumn periods under the support and protection of "Wolf Mother". These facts remind people of the other side of the so-called "wolf nature". Although human beings have not completely uncovered the last secret of the origin of dogs, there is a consensus that the primitive ancestors of dogs were different types of wolves. As for the farther ancestors of wolves and wild dogs, they can be traced back to Eocene 40 million years ago. There is an animal with small body, short limbs and long tail, which can climb trees, be good at flying and be fierce. This is the same ancestor of wolves, foxes and wild dogs today. Second, dogs are domesticated. Dogs belong to wild animals. At the beginning, the motive of human domestication of dogs may be to eat and wear (skin), but later for different purposes such as religion, service and love of play, they were gradually recognized and developed in the long-term breeding process, and there was no such foresight in advance. There is no written record of the original motivation and domestication process of human domestication of dogs. Modern variety show? Although many of them are reasonable and possible, they are all unconfirmed speculations. There is a saying that large wild animals often live around cavemen, threatening the survival of mankind. Humans intentionally or unintentionally throw extra food to wild dogs, let them get as close as possible, and use wild dogs' vigilance against other wild animals to stand guard for people. Another way of saying it may be that primitive people captured more wild dogs and seven wild dog puppies, and instead of killing them all, they fed them for later use. There is another saying: after primitive humans settled down, they often abandoned leftover or inedible meat, bones, skins and so on. Around their residence. At that time, wild dogs foraging everywhere could easily get food near human habitation, so they stayed. Among them, the more ferocious or timid individuals were either killed or driven away, and the tame individuals were preserved. These wild dogs have the opportunity to participate in human hunting activities, experience the sense of superiority dating back to human beings, share some food and gradually put them away. In a word, human beings have changed from killing wild animals to raising wild animals and then domesticating them into domestic animals, which is a great change. The domestication of wild dogs into domestic animals is the result of human labor and the product of human civilization and progress. The ancestor of dogs is wolves. Although they have been bred and domesticated for more than 10,000 years, their genes still retain many primitive wolf habits, and the sociality of living in groups is one of them. Wolves are social animals, usually seven or eight hunt in groups, and each wolf has a different class status in the group. Zoologists are used to calling the leader of the wolf an alpha wolf, and the distribution of food, the settlement of disputes and even the responsibility of offspring reproduction depend on it. The rest of the wolves are also content with their position in the group and obey the leadership of the alpha wolf, which is the wolf's >>

Question 2: Where did the ancestors of dogs live? The ancestor of dogs is wolves. About 65,438+0,000 years ago, human ancestors began to domesticate wolves, and by feeding wolf cubs and driving them to participate in human activities such as hunting, their connection with human society was further strengthened. Then, through generations of artificial selection, more docile offspring are obtained and passed on stably. This is a dog. Therefore, the ancestors of dogs can be said to be all over Eurasia, which is wider than the distribution area of wolves now.

Question 3: What are the ancestors of dogs? Dogs are domesticated by wolves. It first appeared in Mongolia and North America. Due to the bad weather conditions, the wolf's food supply is not sufficient. So wolves often visit human settlements in search of food. Some wolves even stay there, waiting for the food that humans throw away every day to satisfy their hunger. Gradually evolved into a dog over time. Then these dogs were brought to all parts of the world by human beings, and many breeds were produced.

But if you want to say what the ancestors of dogs are, I personally think it should be primitive single-celled creatures.

Question 4: What are the ancestors of dogs? There are two theories about the origin of dogs:

1, monism says that dogs are domesticated by wolves, which means that wolves are the only ancestors of dogs.

2. Pluralism says that dogs are formed by wolves, and in the process of domestication, a small number of canine genes such as foxes and jackals are gradually mixed in.

Either way, wolves are definitely the main ancestors of dogs.

Question 5: What are the ancestors of dogs? The ancestor of dogs is wolves.

Dogs are fierce carnivores.

Dogs can hurt people and other small animals.

Don't dog lovers often flaunt their love for animals?

Dog owners only have dogs in their minds. Why do dog lovers have no sympathy for animals eaten by dogs?

Dog lovers are so narrow-minded. Dog lovers are so hypocritical, dog lovers are so * * *!

Dog owners are selfish and evil people.

Dog lovers are as vicious and cruel as dogs! Dogs are not friends of human beings. Dogs are the devil who spreads rabies.

Question 6: What are the ancestors of dogs? There are two theories about the origin of dogs:

1, monism says that dogs are domesticated by wolves, which means that wolves are the only ancestors of dogs.

2. Pluralism says that dogs are formed by wolves, and in the process of domestication, a small number of canine genes such as foxes and jackals are gradually mixed in.

Either way, wolves are definitely the main ancestors of dogs.

Question 7: What is the ancestor of the puppy? The ancestor of dogs is wolves. Although it has been domesticated for more than 10 thousand years, its genetic genes still retain many primitive wolf habits, and the sociality of gregarious is one of them. Wolves are social animals. They usually hunt in groups of seven or eight, and each wolf has a different class status in the group. Zoologists are used to calling the leader of the wolf an alpha wolf, and the distribution of food, the settlement of disputes and even the responsibility of offspring reproduction depend on it. The rest of the wolves are also satisfied with their position in the group and obey the leadership of alpha wolves. This is the wolf club. Where's the dog? Although dogs have evolved for a long time, they still retain the nature of these wolves, but the object of social interaction has expanded from the same kind to the people who feed them. At home, dogs treat every family member as a member of the ethnic group, live with us, play games and hunt together (go out for a walk). During the period of living with human beings, sensitive dogs have unconsciously made themselves their home. The ancestors of dogs are wolves in East Asia. After analyzing the DNA of hundreds of dogs from Europe, Asia, Africa and North America, scientists found that all dogs in the world have similar gene sequences, so they concluded that all domestic dogs in the world evolved from wolves in East Asia about 6.5438+0.5 million years ago. The ancestors of these dogs and the earliest settlers in America crossed Asia and Europe through the Bering Strait to America. Scientists in Sweden and China have studied the genes of 654 dogs and found that the genes of East Asian dogs are very diverse, which indicates that East Asians tamed wolves into dogs at the earliest. The research results were published in the latest issue of Science, and the researcher who led the research was Peter? Savorin said that humans initially speculated that the ancestors of dogs came from the Middle East based on little evidence, because some archaeological discoveries in the Middle East proved that many animals were tamed in this area. Researchers in the United States, Latin America and Sweden found that dogs with genes similar to East Asian wolves appeared in America before European settlers came to America in the15th century. This shows that the first settlers who arrived in America through the Bering Strait from 1.2 to 1.4 million years ago came to America with tame dogs. Kars, a researcher at Uppsala University in the United States? Vera said that the existence of dogs can explain why settlers in the American continent spread relatively quickly. The two studies differ on when dogs were domesticated from wolves. The dog's mandible was first discovered in Germany, about 6.5438+0.4 million years ago. The research teams of scientists from Sweden and China believe that DNA analysis and archaeological findings show that this dog was domesticated 6.5438+0.5 million years ago. The ancestor of the dog: An Fei Xi Weng (a heavy bear-like dog with a long tail) lived 30-30 million years ago and became extinct in the third era. Pliocene is a transitional form of pseudotaxonomy (small fine-toothed animals and canines, produced in North America). In the fourth century, it was Tomatos (the ancestor of all canines who lived 1500~ 1000 years ago). Wolves are just animals with the same ancestor as dogs, such as raccoons, bears, weasels, civet cats and jackals.

Question 8: Are wolves the ancestors of all dogs in the world? The origin of dogs is actually a mystery, and no one really knows. In Tibetan Canon, the author said that some dogs in the world are made of Tibetan mastiffs, so they are strong.

Question 9: Which nation regards dogs as ancestors? It seems that the She nationality has a similar legend.
