What was the difference between ancient people and animals?

The earliest people had a number of differences from animals:

1. Appearance. The face and body were no longer completely covered with thick hair. The man got upright posture. For this reason, his front (upper) limbs always remained free. It is possible that it was the great functionality of these limbs that led to upright posture. The hand and her fingers were very flexible. The thumb has become especially functional. He became equal to the rest of the 4th.

2. Collective lifestyle and communication. In those distant times, the foundations of speech were already laid. This helped to adjust the joint efforts.

3. The most important thing. This is self-awareness. The man began to understand and realize himself. There was a conscious interaction with subjective and objective factors. Man became man, although the base was not at all alien to him.
