What is evolutionary psychology? In the three and a half centuries since William Harvey proved that the purpose of the heart is to pump blood‚ physiologists have revealed the functional organization of the body in blinding detail. Their discoveries demonstrate beyond question that the structure of the body serves survival and reproduction. Further‚ there is near unanimity among biologists that this functional structure is a product of natural selection. In our century‚ psychologists have developed

Evolutionary psychology is an approach that explains psychological traits such as perception‚ memory‚ and language as adaptations. This approach is focused on how evolution has shaped mind and behavior. Michael Ghiselin coined the term evolutionary psychology‚ making him a key theorist. Other key theorists include Jerome Barkow‚ Leda Cosminde‚ and John Tooby. These three popularized the concept of evolutionary psychology with their book “The Adapted Mind: Evolutionary Psychology and the Generation

Outline and evaluate the evolutionary explanation for gender roles Gender refers to culturally constructed distinctions between femininity and masculinity. Individuals are born female or male but they become feminine or masculine through complex developmental processes that take many years to unfold. For example‚ women usually look after babies while men are the providers. The evolutionary approach argues that gender role division appears as an adaptation to the challenges faced by the ancestral

EVOLUTIONARY THEORY Evolution is the process in which significant changes in the inheritable traits (genetic makeup) of a species occur over time. The validity and value of evolutionary biology are based on continual analysis and interpretation of accumulating science data. THEORIES OF ORGANIC EVOLUTION • Historically three theories • The views of most modern biologists combine the second and third • No evidence of the first theory‚ that of Lamarck LAMARCK: Inherited Acquired Characteristics

behavior naturally occurring? Firm believers of evolutionary psychology assert that‚ “evolution by natural selection‚ is at present‚ the only viable scientific explanation of the existence of complex biological and psychological mechanisms.” (Ploeger et el 2008) These beliefs are highly debatable and only serve as a theory as to why violence occurs. From‚ “Evolutionary Psychology‚” many human behavior ecologists defend the theory of evolutionary psychology. However‚ this does not appeal to many psychologists

Describe and evaluate evolutionary explanations of gender. [8 + 16] During the evolutionary adaptation time period‚ between 10-40 thousand years ago‚ our ancestors were hunter-gatherers. This created a division between men and women. The men would hunt for food and the women would be in charge of the domestic duties such as cleaning and cooking. Doing the domestic chores would have kept women more protected‚ as it is less strenuous and would have guarded the camp whilst the men were out hunting

Albert C. Perez May 10‚ 2017 The article “The evolutionary psychology of hunger”‚ focuses on the “coordinating mechanisms” of the human body which are set up to deal with the physiological and psychological aspects. The general question of the article is how hunger plays a part in influencing these “coordinating mechanisms” in order to solve an “adaptive problem” and to what degree. These mechanisms according to the article influence things such as our ability to focus on tasks depending on the

Evaluation of Evolutionary Theory of Altruism And The Role Of Genes-A Modern View Background: Evolutionary theory holds that organisms with the strongest genes for survival and reproduction do‚ in fact‚ survive and reproduce most successfully. They thus multiply their genes most widely‚ spreading the advantageous genes through whole populations. Ceaseless repetitions of the process can gradually transform species into totally new ones. Such a world seems to have no place for self-sacrificing
