How Charles Darwin's theory of evolution had an Enormous impact on the study of psychology. Charles Darwin’s theory of evolution had a big impact for two reasons. According to David M. Buss a Professor of Psychology at the University of Texas at Austin. “Darwin provided two key theories that guide much of modern psychological research—natural selection and sexual selection.” Because of those theories it helped psychologist see how our ancestors and other animals have adapted to new survival situations to pass on their genes. It has also helped add on to the perspective of cognitive psychology (The Mental processes humans make). One way it has added on is through the error management theory. The error management theory is about
the way humans think and make decisions. These decisions have been made by either biases or metal shortcuts because they have led to reproductive success. But because we use these mental shortcuts or biases it shows psychologist why men tend to think that women are more interested in them then when there is nothing present to show this. It also explains why women tend think that men are less interested in them then when they actually are very interested in them. But this theory does not only talk about reproduction. It also talks about how we perceive things. In this picture both of the orange circles are the same size but some people might perceive the orange circle on the left to be bigger because of the mental shortcuts and biases we use.
