With the advent of the modern entertainment industry, human beings are exposed to a myriad of images each day. Many of the images or sequences of images would have been impossible in the distant past. For example a picture of your grandmother as a teenager, next to a picture of her as an adult approaching senior years. Seeing images of the same person as simultaneously young and old would have been an extremely foreign experience to our ancestors. This luxury of being able to see, compare and contrast an individual’s change over decades, at a glance, is new.
We also encounter an over abundance of gruesome images, sexual images and computer enhanced images. Our evolutionary environment bared only a passing resemblance to the things we see every day on the screen and real life.
Almost everyone reading this will have witnessed a murder or brutal act of violence via television. Yet only a small, small fraction of people would have witnessed such things in primeval times (during peace time). To witness such things they would have had to see them in person. What was once reserved for the unfortunate few who witnessed violent acts, is now seen by nearly all, at least monthly.
Humans also evolved to be in villages of only a few 100 people with tens of potential mates to see and choose from over the course of their entire lives. Now the average person will see 1000s of members of the opposite sex by the time they are 25. What effect does this have on our mating practices?
Our minds did not evolve experiencing many of the conditions that are so familiar to us now in modern society. We still have the same brains our ancestors had 1000s of years ago. How do these new types of conditions effect the way our brains operate and evolve?
