Question

Identify and explain three instances of how evolution has shaped human nonverbal behavior.

Answer 1

There is no theory as such based upon this. But in early mankind these non verbal cues must have been arose out of primary things such running in case of danger, search for shelter, search for food, attracting a opposite sex etc. Non verbal expressions develop when a person is with the other person, if there is a relationship between two people.

For e.g. when fire was discovered the surprise as well as danger symbol,then expression of fear ,making big eyes etc

In case of hunt of animal, running behind the animal,if the animal is caught, makeing the yes symbol by closing fist, or by waving hand to call the other people around.

In case of attracting other person, attraction by eyes, attraction by the gaze by some hand movements would have beeen developed in terms of non verbal cues.
