Why did dogtail grass not become a food in ancient times?

Dogtail grass has nothing to do with wheat, but it has nothing to do with millet. Next, let's talk about the source of the wheat we usually grow, and then talk about the relationship between dogtail grass and millet.

Speaking of the source of cultivated wheat. I'm going to tell you a story. In the early 19th century, there were two people in Japan named Sakamura and Kihara Hitoshi. In the process of studying wheat, they found that the chromosomes of wheat were very complex. Many organisms had two sets of chromosomes, while there were six groups of chromosomes in cultivated wheat. And these six groups come from three different plants. Isn't that weird? Don't worry, let me give you a step-by-step approach.

The original ancestor of wheat, in academia, is called a grain of wheat, that is, two sets of chromosomes. when they grow naturally in nature, there is also a plant called Jiaomai in western Asia, where it often grows. The two plants have grown together for countless generations. They have feelings for each other, and they smoothly combine to produce the next generation. Note that this next generation is the next generation that is sterile. Like a mule born from a combination of a donkey and a horse, it is known that mules are barren. The product of the combination of wheat and wheat can not escape this fate.

However, by chance and coincidence, the product of their combination naturally doubled its success in nature, which became what is now known in academic circles as two-grain wheat.

As a result of the doubling of chromosomes, two-grain wheat gained the ability to carry on the family line, and then flourished in the vast land of western Asia. After countless belts of reproduction, it seems that it inherited a wheat dare to love the character, like the wolf fell in love with the sheep and fell in love with a different species, this species is called pseudo-Spelt goatgrass. The product of the combination of the two is also unable to get rid of the rules laid down by nature, making their offspring infertile.

But fate is so magical, there is no other way, after I do not know how many attempts and efforts, their offspring are also naturally doubled under accidental conditions. At this point, it multiplied into ordinary wheat, that is, the so-called cultivated wheat. This process was re-simulated successfully after 1940. Therefore, it is estimated that there is no half a cent for the relationship between dogtail grass and wheat.

The relationship between dogtail grass and millet. According to legend, Shennong tasted all kinds of herbs in Shanxi, and finally selected millet with large ear, grain weight and high quality from dogtail grass, and taught people to sow and produce. It freed the tribes from hunting life and entered the life of agriculture and animal husbandry.

Since Shennong tasted all kinds of herbs, it has a history of five thousand years. Myth belongs to myth, and when archaeologists excavated the Banpo site in Banpo Village in Xi'an, Shaanxi Province, they found that the millet (su) from more than 6000 years ago was preserved in a set of clay pots. After the millet was peeled, it was what we called millet. In fact, the history of domestication of dogtail grass by the Chinese can be traced back to tens of thousands of years ago. on the other hand, millet can still be degenerated into dogtail grass when it propagates naturally in nature, and it is difficult to distinguish between newly grown dogtail grass and millet. This is the origin of the idiom "the good and the bad are intermingled".
