The Importance Of Human Evolution - amazonia.fiocruz.br

Evolutionary psychology is a theoretical approach in the social and natural sciences that examines psychological structure from a modern evolutionary perspective. Adaptationist thinking about physiological mechanisms, such as the heart, lungs, and immune system, is common in evolutionary biology.

Some evolutionary psychologists apply the same thinking to psychology, arguing that the modularity of mind is similar to that of the body and with different modular adaptations serving different functions. These evolutionary psychologists argue that much of human behavior is the output of psychological adaptations that evolved to solve recurrent problems in human ancestral environments. Evolutionary psychology is not simply a subdiscipline of psychology but its evolutionary theory can provide a foundational, metatheoretical framework that integrates the entire field of psychology in the same way evolutionary biology has for biology.

Evolutionary psychologists hold that behaviors or traits that occur universally in all cultures are good candidates for evolutionary adaptations [6] including the abilities to infer others' emotions, discern kin from non-kin, identify and prefer healthier mates, and cooperate with others. There have been studies of human social behaviour related to infanticideintelligencemarriage patterns, promiscuity The Importance Of Human Evolution, perception of beautybride priceand parental investmentwith impressive findings. Criticism of evolutionary psychology involves questions of testability, cognitive and evolutionary assumptions such as modular functioning of the brain, and large uncertainty about the ancestral environmentimportance of non-genetic and non-adaptive explanations, as well as political and ethical issues due to interpretations of research results.

Evolutionary psychology is an approach that views human nature as the product of a universal set of evolved psychological adaptations to recurring problems in the ancestral environment. Proponents suggest that it seeks to integrate psychology into the other natural sciences, rooting it in the organizing theory of biology evolutionary The Importance Of Human Evolutionand thus understanding psychology as a branch of biology. Anthropologist John Tooby and psychologist Leda Cosmides note:.

Evolutionary psychology is the long-forestalled scientific attempt to assemble out of the disjointed, fragmentary, and mutually contradictory human disciplines a single, logically integrated research framework for the psychological, social, and behavioral sciences — a framework that Sql Analysis Sql And Sql only incorporates the evolutionary sciences on a full and equal basis, but that systematically works out all of the revisions in existing belief and research practice that such a synthesis requires.

Just as human physiology and evolutionary physiology have worked to identify physical adaptations of the body that represent "human physiological nature," the purpose of evolutionary psychology is to identify evolved emotional and cognitive adaptations that represent "human psychological nature.

It describes mental processes as computational operations, so that, for example, a fear response is described as arising from a neurological computation that inputs the perceptional data, e. Under this view, any Domain-general learning is impossible because of the Combinatorial explosion. This implies Domain-specific learning. Evolutionary Psychology specifies the domain as the problems of survival and reproduction. While philosophers have Huuman considered the human mind to include broad faculties, such as reason and lust, evolutionary psychologists describe evolved psychological mechanisms as narrowly focused to deal with specific issues, such as catching cheaters or choosing mates.

The discipline views the Thd brain as comprising many functional mechanisms, [ citation needed ] called psychological adaptations or evolved cognitive mechanisms or cognitive modulesdesigned by the process of natural selection. Examples include language-acquisition modulesincest-avoidance mechanismscheater-detection mechanismsintelligence and sex-specific mating preferences, foraging mechanisms, alliance-tracking mechanisms, agent-detection mechanisms, and others. Some mechanisms, termed domain-specificdeal with recurrent adaptive problems over the course of human evolutionary history.

Evolutionary psychology has roots in cognitive psychology and evolutionary biology but also draws on behavioral ecologyartificial intelligencegeneticsethology source, anthropology The Importance Of Human Evolution, archaeologybiology, and zoology. It is closely linked to sociobiology[6] but there are key differences between them including the emphasis on domain-specific rather than domain-general mechanisms, the relevance of measures of current fitnessthe importance of mismatch theoryand psychology rather than behavior. Most of what is now labeled as sociobiological research is now confined to the field of behavioral ecology.

Nikolaas Tinbergen 's four categories of questions can help to clarify the distinctions between several different, but complementary, types of explanations. Evolutionary psychology has its historical roots in Charles Darwin 's theory of natural selection.]
