Body language originates from animal communication

The origin of body language comes from animals. The relation of body language to animal communication has often been discussed because body language is a product of both genetic and environmental influences. For example the genetic makeup of humans causes blind people to smile and laugh in a funny situation even though they have never seen a smile. Animals’ ideal way of communication compared to humans is completely different. But animals do have perks, for example when participating in a group conversation there is only one person speaking whereas when humans are in a group conversation they may be multiple interruptions because it’s verbal.
