What are the main distinguishing features that characterize a person as a social being?

The main distinguishing features of a person as a social being include the need for communication and being in society.
If a person developed separately from the surrounding world and society, he would never be able to develop language as a way of communication.
In addition, when you are in a confined space, the possibility of development and formation of a personality is almost completely eliminated.
Due to being surrounded by other people, a person forms an opinion, his own thinking, and the natural instincts that he was guided by earlier fade into the background.
