Real scientific understanding: 1. There is something wrong with Engels’s conclusion. Lack of support from biological theory. First of all, labor cannot allow human intelligence to be inherited; secondly, labor cannot make the son of a person who stands up also stand up. It is like cutting off the tail of a mouse, and the little mice it gives birth to still have tails.
2. Can labor be the essential difference between humans and animals? That's not right, all animals are working, at least working to have enough to eat.
3. Not only humans can make tools, but some birds, such as crows, can also make simple tools. Therefore, why humans separated from animals is still a topic
4. Labor is indeed a main feature of intelligent creatures, but this is a phenomenon, and the nature of its origin needs further discussion.
