In ancient China, there was a saying that 6 animals were prosperous, so what kind of animals do 6 animals refer to, 6 animals refer to 6 main kinds of domestic animals, referring to dogs, sheep, pigs, chickens, cattle, and horses.

After obtaining the sheep today, the Tianlong tribe has already obtained dogs, sheep, chickens, and if you add the little Fu Ma, they already have more than half, only the cows and pigs have not.

Based on fossil and relic evidence, the chronological order of the six animals domesticated by humans is: dogs

1. Dogs (31,700 years ago)

The date of domestication of wolves and the breeding of dogs has not yet been determined.

The earliest fossil evidence comes from the Gyuette Caves in Belgium, dating back 31,700 years from the Paleolithic period. The fossil appears to be large, with many canine teeth exposed, and it has been verified that this dog mainly feeds on horses, musk oxen and reindeer. "Paleolithic dogs are very similar in appearance to today's Siberian huskies, but Paleolithic dogs are much larger and about the size of today's shepherd dogs," says Gomoen, a paleontologist at the Royal Academy of Natural Sciences of Belgium. ”

In China, the undisputed earliest dog bones were found 7,000 years ago in the front half of the dog skull and mandibles at the Cishan site in Wu'an County, Hebei Province. The controversy is that in the strata of Zhoujiayoufang in Yushu County, Jilin County, China, the late Pleistocene or Holocene, about 28,000~11,500 years ago, the semi-fossil skull of a domestic dog was found, but its specific age is disputed, but most believe that it is about 10,000 years old.

2. Sheep (10,000 years ago)

The ancestor of the goat was the wild goat, and the ancestor of the sheep was the argali, and since there is more than one species of wild goat and argali, it is inferred that there may be more than one ancestor of the goat and sheep today

Goat and sheep bones are often found at the same time in Neolithic sites in Western Asia. The Zagros Mountains between Iraq and Iran and their vicinity may have been the earliest domestication sites for goats and sheep, temporarily 10,500 years ago, the earliest domesticated goats were found in the Jericho region of Jordan, and sheep appeared in Iraq or Iran 9,500 years ago.

Evidence of sheep breeding has been found in the Longshan culture 4000~5000 years ago in China.

3. Pig (10,000 years ago)

For the time being, the majority of the scientific community is that pigs were first domesticated in Asia, mainly from the European wild boar (which was widely distributed in Asia during the Pleistocene, with fossils found throughout China) and some from the Asian wild boar.

The oldest domestic pig bones were unearthed in 1994 at the site of Hallan Cemi at the foot of the Taurus Mountains in southeastern Turkey (belonging to the Asian part of Turkey), about 10,000 years ago, and at the same time, such ancient pig bones have been found in Jericho in Palestine, Jarmo in Iraq, Catal Huyuk in Turkey and other places, and the age is concentrated between 8000~10000 years.

The earliest internationally recognized evidence of pig breeding in China comes from the Xinglongwa site of Aohanqi in the Inner Mongolia Autonomous Region of northern China (8200~7400 years ago), where a human-pig burial tomb and many pig bones were found, but the pig bones at this time still have the characteristics of wild boars, which are estimated to be the early stage of domestication. The more obvious domestic pig bones were unearthed in Dawenkou, Shandong (5000~6000 years ago)

Evidence not internationally recognized in China includes 113,000,000-year-old pig teeth and pig bones excavated at the Guilin Retort Rock site in Guangxi Province and 9,000-year-old pig bones from the Jiahu site in Wuyang, Henan Province.

4. Chicken (8,000 years ago)

The earliest evidence of chicken domestication comes from Asia, from the domestication of the original chicken, temporarily the earliest fossil evidence comes from the ancient site of Cishan in Wu'an City, Hebei Province, China, the dating of chicken bones is about 8000 years ago, from the measurement data of more than ten complete tarsal metatarsal bones in the chicken bone specimens found at the Cishan site, these chicken bones are closest to the wild wild pheasants in modern birds and slightly larger, but smaller than modern domestic chickens; At the same time, the vast majority of these chicken bones are roosters, and the number of hens is very small, this is because, like modern people, the ancestors of Cishan slaughtered the rooster and left the hen to lay eggs, so there are more rooster bones, which also indirectly proves that the chicken bone specimen unearthed at the Cishan site is indeed a domestic chicken.

However, due to the fact that the Yellow River Basin and the area north of it are low-temperature areas in the Palearctic boundary of animal zonal zoology, no wild wild fowl with high constant temperature have been found. China's Lingnan to Indochina and Bengal, located on the Tropic of Cancer, is the place where the original chicken evolved, so it should also be one of the earliest places for the original chicken to be domesticated into domestic chickens. Therefore, the domestication of chickens must have predated 8,000 years ago.

5. Cattle (8,000 years ago)

Common cattle originated from the original cattle (Bos primie-nius) and began to be domesticated in the Neolithic period. The remains of protocattle have been found in West Asia, North Africa and continental Europe. Based on archaeological remains, most scholars believe that the common cattle were first domesticated in Central Asia and were domesticated in southwestern Turkey more than 8,000 years ago, from which they were introduced to Africa, Asia and Europe

Chinese cattle appeared in the Hemudu site 7,000 years ago as a cattle, and cattle farming techniques began to appear in the Western Zhou Dynasty (2,500 years ago)

6. Horses (6,000 years ago)

The wild ancestors of domestic horses are mainly found at the western end of the Eurasian steppe. The excavation of a large number of horse bones from sites of Neolithic and Bronze Age cultures in the Ukrainian and Kazakh steppes shows the process of domestication from wild horses to domestic horses.

Over the years, the remains of horses have been unearthed more and more in archaeological sites in Eurasia and in the Siberian steppe zone since 4000 BC. But whether the domestication of horses began in one region and then spread to other regions, or whether they were domesticated separately in different regions, remains unclear to archaeologists.
