The ancient man looked very much like a monkey. He had a rough face with a broad, flattened nose, a heavy, chinless lower jaw, and a receding forehead. Above the eyebrows was a roller. Their gait was not yet quite straight, but hopping, and their long arms hung below their knees. People didn’t know how to talk yet. Intelligent man differed from the earliest people in a number of anatomical features, a relatively high level of development of material and non-material culture (including the manufacture and use of tools), the ability to articulate speech and developed abstract thinking.
However, the most ancient people and intelligent people had similarities. All of them lived in groups, carried out joint activities for food, housing and protection from predators.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
