A psychological scientist once raised chimpanzees with his own children. What happened to them later?
In nature, many animals began to slowly change in order to adapt to the environment. For example, giraffes began to grow their necks in order to be able to eat leaves higher on the tree. Some animals were obviously not good at swimming in the early days, but in order to avoid being caught, they gradually evolved into aquatic creatures.

Eating monkeys, drinking cow blood, and washing your face with cow urine is why Africa, the birthplace of mankind, is still uncivilized
Where is the poorest place in the world? It is estimated that many people will say that it is Africa. Because many people in Africa live in primitive grass shacks, people living in the streets and alleys full of sewage are becoming poorer and poorer in the abyss of poverty. Especially in rural areas of Africa, it is very difficult for the local people to use water for their lives. They need to go to places more than ten miles away to fetch water with buckets. Not only that, but there are no roads, railways and communication signals here. Why is Africa, the birthplace of mankind, still uncivilized?

Could extinction really happen? The sixth human mass extinction More than 500 million years ago, the first mass extinction broke out on the earth, the Ordovician mass extinction. In this global extinction event, a total of 85% of the creatures on the earth died. There is no life on land, so the main extinction is marine benthic life. Later studies have shown that it is likely that the gamma-ray burst was responsible for this extinction event.
