What is the idea of the Evolution theory of the government?

Others claim that the state devoloped naturally and gradually out of early family. They hold that the primitive family, of which the fatheras the head of the family and thus the "government", was the first stage in human political devolpment. Over countless years the original family became a network of closely related fam8ilies- a clan. In time the clan became a tribe. When the tribe first turned to settled agriculture- when it gave up its nomadic ways and first tied itself to the land- the state was born.
