Today, I will introduce a good friend of human beings -it is plump and round, pink and cute, bright and bright, delicious. Essence

(Rest assured, your way to open is right)

That's right! It is a family pig, a family pig who loses dreams. It has always wanted to know how the cute self is reduced to a fragrant braised meat.

With dreams, it has always felt that it is different from those pigs who only know about eating and drinking Lazara every day. It has always believed:

You can rewrite the fate of being eaten by humans yourself! Go to the peak of pigs!

But no matter how hard it works, it cannot change the fate of being eaten.

On the bridge, he was angry, and it decided to greet its ancestors:

Why is it? Intersection Give up freedom and fall to the point where it is cursant in the circle of humans?

About the origin of A pig for more than 9000 years

Studies have found that pigs are now more time to earth than humans.

From about 40 million years ago, pig familys have traces in Europe; as of 15 million years ago, pig familys have a wide range of distribution on Asia, Europe, and Africa.

According to the research and research of pork bone fossils, the ancestors of modern pigs are wild boars living in the deep forest or swamp.

According to the characteristics of skull, wild boars can be divided into Asian wild boars and European wild boars. Asian wild pigs are distributed in countries and regions of mainland China, Taiwan, Japan and other countries. European wild boars are mainly distributed in the Tianshan Mountains in Europe, North Africa and Central Asia.

About 9,000 years ago, the Eurasia started domesticated wild boars. It is generally believed that Europe and Asia have domesticated wild boars, forming two very different varieties. The Yellow River Basin in my country is an important domestication center for Chinese pigs.

There are many varieties of wild boars, but there are no reproduction isolation between each other. Therefore, as far as the species level is concerned, the origin of home pigs is single.

But in terms of regional levels, its origin and domestication are diverse. The domesticated wild boar is a activity carried out in different spaces at the same time.

In other words, no matter where it is, humans have found that the wild pork is delicious.

(Pig and pigs cry QAQ)

The varieties of modern home pigs have gradually evolved from wild boars in different places.

The domestication process of Azhu

The Neolithic era was the beginning of human nomadic turning to settle lifestyle. Humans and wild boars who had not committed rivers in well water. With whether you die or I live a "intimate contact".

At first, human fighting tools were relatively simple, and they couldn't beat strong wild boars at all. They could only get some old and weak disabled players.

It may be that wild pork is too delicious, and our ancestors vowed secretly:

keep it up! To make progress! Intersection To eat more pork! Intersection

With the development of human society and the improvement of labor tools, human hunting technology has made rapid progress, and the number of wild boars is increasing. The supply is greater than demand, so that the meat has surplus.

At this time, the ancestors had a clever movement. Since we have successfully domesticated dogs, the pigs are not enough! As a result, the wild boar turned into a pig.

A Zhu felt that the quality of life suddenly had a qualitative leap. There was a place to sleep, something to eat, and to walk around without the wind and dust.

Because A pig does not leave home (actually lazy), he can grow and grow fast, and gradually be appreciated by humans, which prompts the domestication speed of pigs to greatly surpass other livestock.

Like other wild animals, the process of domestication has gone through five stages:

Streaming based on hunting;

The non -blocking type based on domestication;

Wild stocks with limited space;

There are grazing with special personnel;

Circles based on sufficient feed.

Due to the changes in lifestyle, breeding management, and the participation of manual selection, A pig's habits, body, and physiological functions have undergone great changes.

Azhu's historical highlight moment

In the Western Han Dynasty, which is more than 2000 years ago, my country has become an excellent pig species, which has epoch -making gaps between the nursing pigs and wild boars.

And another huge change occurred in the 18th century Britain: people used several ancient pig breeds to cultivate modern meat species with large body, fast growth, and plump figure.

After the Opium War, more than a dozen foreign pigs from all over the world poured into China. Many varieties of foreign pigs have a positive impact on Chinese pig species, such as Yorkshire pigs, Bucks summer pigs, long white pigs, and Soviet big white pigs.

It is worth noting that these foreign pigs are mostly white pigs. On the contrary, most of the original pigs in our country are mostly black pigs.

Black pig breeding ability, strong resistance to reverse resistance, and good meat quality, but there are great lack of growth performance and carcass. In order to make our country's pig species better, Chinese breeding experts use more than 50 pig species or new products by local pig species and foreign pig species introduced abroad, which greatly enriches my country's pig species resources. Black pigs gradually occupy home.

And pork has gradually become the most common food on the table in my country, and every part of the pig can become a dish.

For example: rice noodle meat, Yipin meat, chestnut meat, altar meat, red meat, yellow sauce meat, sauce tofu, dried stove meat, stewed meat, sticky meat, meat, pine meat, canned meat, roast, roast Meat, large meat, barbecue, white meat, red elbow, white elbow, smoked elbow, crystal elbow, beeswax elbow, pot of pot, cooked elbow strip ...

However, the wild pork is still a king compared to home pigs.

Studies have found that the content of protein in wild pork is 242 mg/g, which is higher than 132 mg/g than home pork. In addition, we can see that wild pork is more red than home pork, which is also because the iron content of wild pork is higher. The iron content in wild pork is 27.4 mg/g, higher than 10.0 mg/g of home pork.

(Academic Junxiao Tip: Although the wild pork is delicious, don't try it easily, cherish life, Peace & Love)

In the final analysis, wild boars and pigs are brothers of a mother, but the former is left in the mountains and self -employment, and the latter is raised by human domestication.

If there is a dream of a dream pig escapes the circle, after successful jailbreak, it will reappear the habits of wild boars and become more expensive!

In summary, our friend A Zhu still has the opportunity to regain freedom and go to the peak of pigs!

In fact, I don't know if Azhu had thought about it: accepting being eaten frankly, cooperating with raising and being taken care of, so that the race can be better reproduced. This survival strategy is very strategic!

Regardless of whether it is a person or a pig, when you come to this world, you always have to face death. You have to die early and die. Is it better to focus on the living day?

If you think about it, this is the case for pigs. The great wisdom of survival is really different, and it is better to lie flat.
