What are the ancestors of geese?

In terms of origin and evolution, geese raised at home are all artificially trained by wild geese (China geese generally originated from Yu Hongyan, while European geese and Ili geese mostly originated from gray geese), which are a kind of birds belonging to Rhus, while swans are a kind of swimming birds belonging to the genus Swan.

Goose raising has a very long history. In ancient Egypt in 2500 BC, there were detailed records of keeping geese in pens and raising foie gras. Temples in the Roman Empire once offered offerings to help them find invaders? God goose? .

China also has many stories about geese:

Wang Xizhi of Jin Dynasty liked to appreciate the singing of geese. He heard that an old woman had a goose that was good at singing, so he went to watch it. As a result, the old woman heard that Wang Xizhi was coming and slaughtered the goose for Wang Xizhi, which made the latter cry.

At the age of seven, King Robin of the Tang Dynasty watched geese swimming in the pond and wrote Ode to Goose, which has been handed down for ages? Goose, goose, Xiang Tiange, white hair floating green water, red palm clear waves? .

The ancestors of domestic geese are wild geese, which were domesticated by humans about three or four thousand years ago, and now they are raised all over the world. But you know what? The domestic geese raised by Europeans are actually different from those raised in Asia (mainly China).

In China, almost all geese have a big head. They look like old people (see above).

The European domestic goose doesn't have this feature, just a dull-looking son (see the picture below), but its fighting capacity is as important as that of the Asian goose.

The fundamental reason for their different appearances is that these two domestic geese are actually domesticated by two different geese.

The ancestors of Asian domestic geese are geese.

Yes, that's right, the kind that flies across the sky every autumn and then lines up for a while? One? So, will you arrange it later? People? Words soar above our heads? Goose? .

Compared with domestic geese, Hongyan is stronger and more compact. Its light brown belly and dark brown wings are perfect camouflage in the yellow grass, and its black beak bulges slightly on its forehead, indicating their blood relationship with Asian geese.

However, it should be noted that the head of geese only has a slightly raised forehead, and some individuals even don't stand out at all. The prominent forehead of China Goose, like the red sarcoma of wart-nosed duck, is the result of artificial breeding.

Let's talk about the ancestors of European domestic geese first. They are Ansel Ansel, a grey goose that lives in Europe and West Asia.

The color of geese is actually very close to that of geese, but the beak of geese is bright orange and yellow, while the beak of geese is black, which is the most obvious and intuitive difference between them. You can tell at a glance.

There is another difference, that is, some Hongyan individuals have prominent foreheads. After being domesticated into China geese, people also choose and specialize this head structure. But the gray goose has no protrusions on its forehead, so the European goose domesticated by the gray goose does not have protrusions on its head like the Asian goose.
