What are the fundamental differences between humans and closely related species?

There are several differences between humans and animals. The main thing is that people can make tools and use them. A man, unlike an animal, owns speech. He has a mind and he can reason. Animals are incapable of creative activity, but man can create, create material and spiritual values. By their actions, people change the world around them. Animals act instinctively and do not separate themselves from nature. A person can control his behavior and choose a role in society.
