Human beings, who are said to have been born in Africa, are roughly " monkey people " while various strains of human beings are born and disappear. ⇒ Original ⇒ old man ⇒ newcomer It is said that it has evolved through the stages of.
* However, it is said that a paper with evidence denying Darwin's theory of evolution came out in 2018, so the textbook may change in the future.
Meanwhile, major environmental changes will occur on a global scale.
Cooling and drying have reduced the forest areas that were originally abundant in Africa.
Our ancestors, modern humans, are
I have come to suffer from cooling and drying. So modern humans are
- To get food and water
- To find a place to hide from the enemy
Escape from the African Continent.
Please refer to the illustration below for the movement route and age of human beings after escaping from Africa.
Among them, the classification by "change in appearance" as shown in the illustration below is race . Will be called.
Of course, not only changes in appearance, but also differences due to words and habits have begun to appear. If people with similar appearances, words, and customs gather together, wisdom and lifestyle ideas that may be useful will spread.
By the way, some words are derived from a common language, even if they are different words in the end. "English and German and Dutch", "Latin and French", etc. Similar language groups derived from such a common language are language families Is called.

With such a living environment in place, Paleolithic Lithic reduction like Hunter-gatherer society Is farming / livestock The reason for the change was once again due to changes in the global environment. The glacial period is over and the earth is warming I did.
Large beast during the glacial period There were many in the places where humans live.
The large beast disappeared, and it was no longer possible to stand up in the traditional lifestyle.
In that difficult situation, humanity is farming / livestock We have created a new means of obtaining food. It is said to have started in West Asia around 8000 BC.
At first, it may have been a kick to say, "I found the same plant growing from the place where I left behind the seeds of the plant I'm eating." This event, which was a major transformation in human history, was a agricultural revolution . It is also said to be.
Agriculture And livestock At the beginning of the farming, I was farming while moving, but eventually I settled on the side of the water source and farming / livestock Will be done.
That was the key to that.
Irrigated agriculture is. Irrigated agriculture It wasn't in areas with heavy rainfall, but in areas where we had to constantly seek ways to use water. In areas with a lot of rain, it is possible to use rainwater in our daily lives, so we didn't have to bother to secure water.
Irrigated agriculture as a result of the combination of water use and agriculture Is thought to have been born. It was the beginning of the wisdom of areas where it was difficult to secure water in arid areas.
As irrigated agriculture begins and the population grows, it becomes necessary to construct rivers and cultivate land for further food production. Furthermore, the difference between rich and poor will come out depending on the yield of crops. From the above circumstances, a mechanism to lead people was completed in a large number of people. So-called nation is born To do.
Initially Tigris / Euphrates Mesopotamia in the basin It started from Nile Basin (Egypt), Indus River (India), Yellow River / Yangtze River Basin A similar mechanism was created in a large river basin such as (China).
I want to read it together
Birth of ancient civilization
As I mentioned in the previous article, human beings have evolved and spread all over the world, and the change from hunter-gatherer life to farming and livestock life has greatly changed people's lives, and the structure of a nation was completed and civilization was born.
