What distinguished ancient people from animals?

The most basic feature that distinguishes humans from animals is self-awareness. This means that a representative of this species understands himself, realizes his role in his own life and the life of society. Animals do not have this feature. A person distinguishes colors. A person can make articulate sounds. Bipedal locomotion is characteristic. The appearance of the most ancient man, although it retained some features of animals, already had the features of a modern man. Living in caves has evolved over time into living in dwellings of branches, bones and animal skins.
