Pygmies

The Bambuti Pygmies were a tribe of Africa that was isolated from all civilization and had no contact with other people until Colin Turnbull, an anthropologist that was studying civilizations in Africa, encountered this tribe and realized something real interesting, publishing some books on these observations and his discoveries. He had a Phd and had a kind of rough childhood, he saw many things and swore to defend and help out people who were needed and were minorities, in his attempts to study little tribes in Africa he discovers something really crucial about perception and the human mind, such as that humans learn about all the tricks in perception, such as things appearing smaller when they are further away from the human eye, etc. Things such as how a buffalo looks further apart compared to how it looks really close,  the Bambuti Pygmies had not seen anything from long perspective since they were surrounded by trees and could not see things on a long perspective and when they saw things far away they got really scared, doing this Colin Turnbull learned that people learn that things further away are the same thing although they look smaller than what you are accustomed to see. This was a crutial and really important observation on the subject of perception and what it consist of, on how everybody see things on a different way. This further helps understand the human brain and what how we learn certain things, things that we think we have from birth, but in fact we have learned to see things in certain ways.
