The question about the ancients is as follows

Australopithecus. The common ancestor of humans and apes, Australopithecus began to evolve in different directions. Australopithecus acquires an upright state, with primitive tool-making and simple communication of language and gestures.

Because the laryngeal structure of Australopithecus is not suitable for pronunciation, it can only communicate with vocalization-like language and gestures, which is also the biggest difference between humans and Australopithecus.

Capable stage. At this stage, the brain size of the ape-man doubled to more than 800 cubic centimeters.

Homo erectus. Cooked meat eaten provides more energy than raw meat that can be eaten.

Homo sapiens stage. Homo sapiens continued to grow in capacity, and thus art, proving that abstract thinking had progressed, and that new social structures had been formed as a result of the Neolithic ecological upheaval, which had finally led to our present world.

Australopithecus.

Homo sapiens. It's in the encyclopedia, it's quite comprehensive.

The lieutenant is from the Han Dynasty. The people who live in the city are not necessarily rich, and the rich people do not necessarily live in the city. If there is a case outside the city, he will go to the county office to report to the local magistrate.

In the Ming Dynasty, there were both rich and poor people living in the city, and there was a distinction between "noble community" and "slum" and "shantytown" in the city, and even a large number of farmland and vegetable fields existed in the city

- Even a Beijing teacher like Nanjing is like this.

The countryside is basically a gentry society, and there are also "haoqiang" and the like - some of these people are famous literati families; Some are retired former officials - this is the gentry

Some are local tyrants (with family power or personal prestige and force).

Cases between urban and rural areas are all handled by Baojia and Lizheng, and ordinary matters can be solved under the auspices of the squires - at that time, the government's control ability was weak, and the power did not go to the countryside, and the grassroots incidents were often controlled by officials, squires and clans.

Only serious incidents (such as **) will be reported to the official, and the county will send a public servant; Inspections may also be accepted in the vicinity.

In the old days, it was an important first-level organization, and in the city it is equivalent to the current street and community; In the countryside it is equivalent to an administrative village.

In the Ming Dynasty, there were many towns, but this town was only conventional, not a first-class government in the legal sense. There is no such thing as a "town mayor", but in towns with developed transportation, there will be inspectors and tax collectors, and some large towns even have permanent general judges or acquaintances

At that time, in feudal society, there were dynasties.
