Evolutionary Psychology Facts

Evolutionary psychology is a field of study that aims to explain psychological attributes, such as memory, perception, or language as a functional product of natural selection or sexual selection. Evolutionary biology usually adopts an adaptationist point of view to physiological mechanisms such as the heart, lungs, and immune system. This is the same line of thinking applied in evolutionary psychology.
According to evolutionary psychologists, human behavior arise from psychological adaptations which was a result of attempts to resolve recurrent problems in human ancestral environments. For them, humans have acquired special mental capacities for developing language without inheriting no ability to read and write. Evolutionary psychology also state that humans also acquire other adaptations such as inferring the emotions of other people, determining relatives from non-relatives, to work with others, to name just a few.
For evolutionary psychologists, behaviors and emotions are universal. Fear of snakes and spiders are merely evolved adaptations which interact with cultural inputs to generate certain behaviors. This opposes the idea that human mental faculties are general-purpose learning mechanisms. Some of the fields closely connected with evolutionary psychology are behavioral psychology, human behavioral ecology, dual inheritance theory, and sociobiology.
Evolutionary psychology rose from the current discipline of sociobiology as an attempt to analyze the human race through sociobiology. In reaction to the controversy, evolutionary psychology was introduced by anthropologist John Tooby and psychologist Leda Cosmides as a field of sociobiology. It has become less controversial by diverting from questions on human biodiversity.
Evolutionary psychology is a hybrid discipline that gets its insights from modern evolutionary theory, cognitive psychology, biology, economics, anthropology, computer science, and paleoarchaeology. There are five core premises where evolutionary psychology is based. For psychologist David Buss, these principles include:
1.Manifest behavior is determined by underlying psychological mechanisms, information processing devices located in the brain, in association with the external and internal inputs that activates them.
2.Evolution by selection is the only recognized causal process which has the capacity to generate complex organic mechanisms.
3.Evolved psychological mechanisms are functionally designed to address adaptive problems that have recurred for humans over the history of their evolution.
4.The processing of information in many evolved psychological mechanisms are designed to be adaptively influenced by certain classes of information from the environment.
5.Human psychology involves a large number of functionally specialized evolved mechanisms with the sensitivity to certain forms of contextual input, which are blended, coordinated, and integrated with each other to generate manifest behavior.
