cultural adaptation biology
Are Psychological Adaptations Even Possible? This key adaptation is the one that enabled humans to understand other individuals as intentional agents like the self. 23 January 2011. Cambridge: Cambridge University Press. Evolutionary psychology. New York: Psychology Press. Different neural mechanisms are specialized for solving problems in humanity's evolutionary past. Initial studies show the importance of these components in early life for positive child outcomes. Neuberg, S. L., Kenrick, D. T., & Schaller, M. (2010). Evolutionary psychology is founded on several core premises. One of the keys to the process of adaptation is biological or behavioral variation, thereby implicating the notion of selection and the processes of decision making (Bates, 2005). 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. Web. Schacter, Daniel L, Daniel Wegner and Daniel Gilbert. , If the theory that language could have evolved as a single adaptation is accepted, the question becomes which of its many functions has been the basis of adaptation. Oxford: Oxford University Press. Van Vugt, Mark & Ahuja, Anjana. Biology Notes Chapter 1 Characteristics of Life (Pg. This genetic event opened the way for new and powerful cultural processes but did not specify the detailed outcomes of behavior we see today. Buss (2011) notes that these methods include: Cross-cultural Consistency. through the increased risk of injury when defending offspring against predators, the loss of mating opportunities whilst rearing offspring and an increase in the time to the next reproduction. Humans have biological plasticity, or an ability to adapt biologically to our environment. Adaptation is a characteristic feature of all living organisms. Workman, Lance and Will Reader (2008). clothing - not a physical adaptation because it is not a biological adaptation therefore it is cultural.  Liking and disliking, he says, evolved to help present day humans' ancestors form coalitions with others who reciprocated and to exclude those who did not reciprocate. One example is the fact that although about 10,000 people are killed with guns in the US annually, whereas spiders and snakes kill only a handful, people nonetheless learn to fear spiders and snakes about as easily as they do a pointed gun, and more easily than an unpointed gun, rabbits or flowers. a visual image of a spider, and outputs the appropriate reaction, e.g. Evolutionary psychology. Resolving the debate on innate ideas: Learnability constraints and the evolved interpenetration of motivational and conceptual functions. In one such adaptation, the eggs or larvae are distasteful, inedible, or apparently harmful to potential enemies. In biology this general idea has been coopted so that adaptation has three meanings. Defenders of the truth: The battle for science in the sociobiology debate and beyond. 161-184. Evolutionary psychologists are also interested in identifying these proximate mechanisms (sometimes termed "mental mechanisms" or "psychological adaptations") and what type of information they take as input, how they process that information, and their outputs. Cultural change can have many causes, including the environment, technological inventions, and contact with other cultures. 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. Today, the theory of cultural evolution is an (often unstated) underpinning for other, more complex explanations for cultural change, and for the most part archaeologists believe that social changes are not only driven by biology or a strict adaptation to change, but by a complex web of social, environmental, and biological factors. While each of these hypotheses has its merits, each is still highly speculative and requires more evidence from different areas of research (such as linguistics and anthropology). The key adaptation is one that enables individuals to understand other individuals as intentional agents like the self. Evolutionary psychologists seek to understand psychological mechanisms by understanding the survival and reproductive functions they might have served over the course of evolutionary history. The key adaptation is one that enables individuals to understand other individuals as intentional agents like the self. A classic example is shown by the melanistic (dark) phenotype of the peppered moth (Biston betularia), which increased in numbers in Britain following the Industrial Revolution as dark-coloured moths appeared cryptic against soot-darkened trees and escaped predation by birds. Corrections? ", Evolutionary psychologists generally presume that, like the body, the mind is made up of many evolved modular adaptations, although there is some disagreement within the discipline regarding the degree of general plasticity, or "generality," of some modules. 2K views ), The Innate Mind: Structure and Content. Researchers in the emerging field of evolutionary social psychology have made many discoveries pertaining to topics traditionally studied by social psychologists, including person perception, social cognition, attitudes, altruism, emotions, group dynamics, leadership, motivation, prejudice, intergroup relations, and cross-cultural differences. Psychology will be based on a new foundation, that of the necessary acquirement of each mental power and capacity by gradation.  These social motivations match what evolutionary psychologists expect to see in adaptations that evolved to maximize the benefits and minimize the drawbacks of reciprocity. weaving. One of the most common forms of constraint involves the function of anatomical traits that differ in size. , When endeavouring to solve a problem humans at an early age show determination while chimpanzees have no comparable facial expression.  He found evidence that humans share at least five basic emotions: fear, sadness, happiness, anger, and disgust. , 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. Durrant, R., & Ellis, B.J. On the other hand, ancestral humans did not read or write, thus today, learning to read and write require extensive training, and presumably involves the repurposing of cognitive capacities that evolved in response to selection pressures unrelated to written language. 2004 Evolutionary thought in Psychology: A Brief History. Cross-Cultural Adaptation Theory. , Currently several competing theories about the evolutionary origin of language coexist, none of them having achieved a general consensus. Breton , C. ( 2019 ). Naturally Selected: The Evolutionary Science of Leadership (2011). (2003). (2011). 5–67). Encyclopædia Britannica.  Evolutionary psychologists say that animals from fiddler crabs to humans use eyesight for collision avoidance, suggesting that vision is basically for directing action, not providing knowledge. Raison, C.L, Miller, A. N. (2012). Experimental approaches are important for showing that any small variability, as in many physiological or behavioral differences, is an adaptation.  Evolutionary psychologists respond that they do know many things about this environment, including the facts that present day humans' ancestors were hunter-gatherers, that they generally lived in small tribes, etc. Evolutionary Psychology. Recently emerging multistep frameworks or stage models are examined, as these can systematically guide the development of culturally adapted EBIs. Consistent with the theory of natural selection, evolutionary psychology sees humans as often in conflict with others, including mates and relatives.  Moral indignation may have evolved to prevent one's altruism from being exploited by cheaters, and gratitude may have motivated present day humans' ancestors to reciprocate appropriately after benefiting from others' altruism. Until 1964, it was generally believed that genes only achieved this by causing the individual to leave the maximum number of viable offspring.
