Question

What were the mode of communication of early human?​

Answer 1

Answer:

Long before the earliest writings of the Sumerians and the Egyptians were developed, people communicated with each other by a number of different methods. Early humans could express thoughts and feelings by means of speech or by signs or gestures. They could signal with fire and smoke, drums, or whistles.

These early methods of communication had two limitations. First, they were restricted as to the time in which communication could take place. As soon as the words were spoken, the gesture was made, or the smoke was blown away by the wind, they were gone and could not be recovered, except by repetition. Second, they were restricted as to space. They could be used only between persons more or less close to each other.
