strengths and weaknesses of evolutionary theory page 386

The history of false predictions generated by a theory tells us about its strengths and weaknesses, and how and why the theory is believed to be true. McNamara (2004) pointed out that in rats the mother must be in NREM sleep for oxytocin release to occur. Evolutionary psychology suggests that human behaviour and phenomena can be explained through the process of natural selection. There is strong evidence that emotions affect cooperation, but less evidence that negative emotions are any more effective than positive emotions in this respect. Also some Christians believe that it shows an ever-working God, so there is still space for a creator God. Traits which offered our ancestors a survival or reproductive advantage in our environment of evolutionary adaptation (EEA) would be passed on to offspring and as a result … ... What are the strengths and weaknesses of our current psychological adaptive capacities? There is also strong evidence that dreams provide images that are used in cultural and religious contexts to promote cooperation and group unity. Central to McNamara's (2004) costly signaling theory of REM dreams is the impact the dream continues to exert in the waking life of the individual. Biggest Weakness of Darwinism: The Mechanism. (2007). The Attachment Theory is how one is attracted to another human being and how one builds relationships with different people (Chisholm, 1996). Rather, I am primarily cautioning amateurs (such as LW regulars) about some of the caveats involved in (armchair) evpsych and noting the rigor required for good theories. The human homologues of these genes, PEG3/PW1 and PEG1/MEST 1 are imprinted; PEG3/PW1 is paternally expressed in the brain, but according to Isles and Holland, the imprinting status of PEG1/MEST1 in the brain is unknown. 806 8067 22 To begin with, scientific usage of "theory" differs from everyday usage.In common usage a theory is simply a conjecture. Calling for strengths and weaknesses of evolution was again a contentious issue when the TEKS came up for revision in 2008 (Scharrer 2008). In diverse animal taxa, poor sleep negatively impacts development, cognitive abilities and longevity. Although this criticism often confuses ultimate and proximate explanations, there is one division between the evolutionary and feminist positions that cannot be bridged, its ultimate origin. Furthermore, as described above DNA methylation can occur as a result of mother-infant interaction, and the epigenetic changes are then passed on to the next generation. McNamara's (2004) evolutionary theory of dreaming accounts for all the patterns of brain activation that have been shown through imaging, and for the neural substrate of dreaming as described in Domhoff (2003). But evolution is no longer a hypothesis. © Copyright Get Revising 2020 all rights reserved. "Strengths and Weaknesses" article, with text of Texas "TEKS 3A" that requires teaching weaknesses in the classroom. Evolutionary psychology is founded on a model of ancestral human reproductive ecology (the EEA), yet the current version of this model is woefully out of date. Starting this summer, the state education board will determine the curriculum for the next decade and decide whether the "strengths and weaknesses" of evolution should be taught. McNamara (2004) reviewed Kuiken and Sikora's (1993) study in relation to the emotional processing functions of dreams, but McNamara didn't refer to the emotional content of their study, even though McNamara's theory revolves around the central idea that negative emotions in dreams have a continuing impact on waking life. I had my own insight into this a few years ago when one of my positive psychology colleagues urged me to join a gym and lose weight. Not only are aspects of maternal behavior caused by imprinted genes, but also maternal behavior causes epigenetic effects in the offspring, which are then transmitted to future generations (Champagne, 2008; Champagne and Meaney, 2007; Weaver et al., 2004). We do not say that the function of the waking state is learning simply because learning takes place during the waking state.

(, Liljelund, P., Handforth, A., Homanics, G.E., and Olsen, R.W. To understand potential strengths as well as weaknesses and criticisms of these theories. Costly signaling theory was also used by McNamara (2004) to explain cultural and religious uses of dreams. », How can people not believe in the Big Bang? Misconceptions about natural selection and adaptation: . Biologists define an acquired characteristic as one that has developed in the course of the life of an individual in the somatic or body cells, usually as a direct response to some external change in the environment or through the use or disuse of a part. Basically, because developmental sleep processes may affect brain development, sleep behaviors may have an impact on how much energy an individual directs toward somatic versus reproductive strategies. Max Weber, The Theory of Social and Economic Organization, trans. The evolutionary theory like any other sociological theory is strived with strengths and weaknesses. Cellular and neuronal signals are also exchanged during REM and NREM sleep. It is difficult to test the ideas of evolutionary. To illustrate this model, McNamara described the changes in maternal sleep that occur during pregnancy. McNamara (2004) reported that REM dreams have been found to be more emotional than NREM dreams: “NREM dreams were characterized as being less vivid and more thoughtlike than REM dreams” (p. 73). Through DNA methylation, effects of maternal behavior change the oxytocin-estrogen interactions, estrogen receptor levels in the hypothalamus, and oxytocin receptor binding in the hypothalamus (Champagne, 2008; Champagne and Meaney, 2007). By identifying them, I am able devise a plan to improve my areas of weakness, while using my strength to my advantage. The Intelligent Approach: Teach the Strengths and Weaknesses of Evolution Jonathan Witt July 25, 2005 Intelligent Design. History of Lamarckism, an early theory of organic evolution. In 1984, evolutionary molecular biologist Michael Denton wrote Evolution: A Theory in Crisis, a very revealing book describing in detail the very weaknesses in evolution that Dr. Scott and the NCSE maintain do not exist. The Myth of the Recapitulation Theory German biologist Ernst Haeckel proposed in 1866 that “ontogeny recapitulates phylogeny”. (p. 96). (p. 133).

McNamara (2004) gave a brief description of how life history theory relates to sleep. Conversely, dreamer-initiated friendliness occurred in 90% of the NREM dreams and only 54% of the REM dreams. During the 2003 hearings, creationists urged textbook publishers to include examples of alleged strengths and weaknesses of evolution from the Discovery Institute Fellow Jonathan Wells's book Icons of Evolution (Wells 2000). It doesn't seem necessary to insist that these signals are also costly in the sense of being negative. 3. conflicts between Printed in the United States of America Max Weber, From Max Weber: Essays in Sociology, ed. In situating his theory of REM sleep dreaming within evolutionary theory, McNamara (2004) provided a detailed description of the appearance of REM and NREM sleep states in mammals and argued that these distinct sleep states emerged from a combination of sleep states that first appeared in monotremes. Clearly, REM poses a risk to human health and is thus costly from a biological perspective, a feature that McNamara used to associate REM sleep and dreams with costly signaling. (p. 249). Also some Christians believe that it shows an ever-working God, so there is still space for a creator God. The “strengths and weaknesses” language was slipped into the curriculum standards in Texas to appease creationists when the State Board of Education first mandated the teaching of evolution … Thus, there will be conflict in that the fetus will attempt to extract the maximum amount of resources for itself, while the mother may have other interests. Although this seems plausible, McNamara does not offer any evidence to support this theory. Just to add a bit to Ian's three points and the other excellent answers here: The basic rule for evolution is: don't be any stronger than you need to be. He also described a positive correlation between REM sleep and breastfeeding, and between breastfeeding and increased activity in the occipital-temporal-parietal area of the infant's brain. McNamara and Szent-Imrey (2007) supported this argument by showing that healthier individuals are more able to bear REM deprivation and the subsequent increased REM without ill effects: “Healthier individuals showed fewer signs of ill effect of the [REM] deprivation procedures. (p. 16). As noted by McNamara (2004), increased REM sleep is also associated with increased risk of mortality. McNamara (2004) described how REM and NREM processes interact in various conflicting patterns, for example, to influence the release of and affect the circulating level of different hormones. In addition, he developed a distinctive version of institutional theory which, over time, has generated productive linkages with evolutionary economic and resource-based theories of organizations – strands of work feeding into management strategy. This product could help you, Accessing resources off campus can be a challenge. By "the theory of evolution" I mean to signify the notion that new, superior species arise through the processes of genetic variation and natural selection. McNamara (2004) based his claim about negative emotions in dreams in part on dreams scored using the Hall/Van de Castle scoring rules. Some insist that only Darwinism be taught in the science classroom while others are bent on including the Biblical account alongside modern evolutionary theory. As such, it seems that this trait would be self-limiting, but McNamara (2004) and McNamara and Szent-Imrey (2007) did not address this. Evolutionary theory holds that an organism's traits change over long periods of time to adapt in ways that enhance the organism's fitness for survival. Get Revising is one of the trading names of The Student Room Group Ltd. Register Number: 04666380 (England and Wales), VAT No. At the very least, negatively toned dreams are more often remembered than are positively toned dreams, and this fact must contribute to the ways in which dreams function to affect waking mood and behavior. In agreement with this, McNamara (2004) posited that REM sleep and dreaming, although costly, are traits that have evolved to increase fitness. Create a link to share a read only version of this article with your colleagues and friends. Theory of evolution Evolution of human beings over millions of years from ape-like ancestors. McNamara stated that emotional content of dreams is uncertain: “Further studies are needed to clarify emotional content of typical dreams” (p. 133). The theory of evolution, to which reference has been made, actually has no bearing on the Torah account of creation. Supporting a genetic basis for sleep, Maret et al (2007) found that in mice, Homer1a, which is involved in intracellular calcium regulation and synaptic glutamatergic signaling, is the brain molecule that responds most clearly to sleep deprivation: “Our findings suggest that Homer1a might represent the molecular link between sleep, cognition, and neuropsychiatric disorders” (p. 20095). One of the most important aspects of the evolutionary theory is that it deals with systems, structures, adaptations and change as part of social stratification. elaborate Watson’s Theory of Human Caring and elucidate its strengths and weaknesses in the acute care setting. ... Turchin’s theory deals in large part with … McNamara's (2004) theory that residual negative affect from dreams creates a costly signal that enhances cooperation was based on the preponderance of negative emotions in dreams; it would then follow that the majority of people experience these negative moods.

Morewedge and Norton (2009) found that in addition to creating emotions that carry over into waking life, dreams impact many people's waking feelings, thoughts, and actions more than actual waking experiences do: We suggest, however, that people do not merely lend the same amount of credence to thoughts that occur in dreams as thoughts that occur while awake but actually treat the content of their dreams as more meaningful than the content of similar waking thoughts. (, Kozlov, S.V., Bogenpohl, J.W., Howell, M.P., Wevrick, R., Panda, S., Hogenesch, J.B. and Stewart, C.L. McNamara argued that this continuing impact sets a negative emotional tone, creating a handicap that positively influences the individual's meaningful communication interactions with others. However, it does seem clear that these signals are hard to fake, and thus would facilitate honest, emotionally meaningful communication. Below is a summary of the six main psychological approaches (sometimes called perspectives) in psychology. Thus, natural selection would not have favored REM sleep and dreaming unless the benefits overran the costs that went into producing them. By ... organisms by evolutionary biologists are sufficient to understand and explain the events of the Cambrian or whether evolutionary theory needs to be expanded to include a more diverse set of macroevolutionary processes. Although McNamara agreed that REM and NREM are involved in memory function, he argued that this involvement does not explain the function of sleep from an evolutionary perspective: Thus, even if memory consolidation occurs in sleep, this does not tell us what the specific function of sleep may be. Because dreams are involuntary, telling one's dream to another is providing an honest view of one's internal processes. Although costly signaling may “emerge from conflict,” according to McNamara, “it may operate to allow for cooperative alliances and honest communication between individuals who may otherwise have conflicting genetic interests” (p. 14). The evolutionary theory like any other sociological theory is strived with strengths and weaknesses. McNamara (2004) described genes that regulate sleep, including separate genes that regulate REM and NREM, and presented information that indicates that some genes regulating REM are imprinted by paternal alleles, and some genes regulating NREM are imprinted by maternal alleles, lending support to his theory that genomic conflict influences the interactions of REM and NREM sleep. As described in these studies, genomic conflict plays a role in growth, development, sleep regulation, maternal behavior, and maternal-infant interactions, supporting McNamara's claim for the role of genomic conflict in REM and NREM sleep and dreams. Limitations This theory focuses solely on the traditional mother role. Evolutionary Psychology. In reviewing the effects of genomic imprinting on brain development, Wilkinson et al. One type of costly signal was discussed above: the emotional handicapping that occurs because of the predominance of negative emotions in dreams, which McNamara posited increases cooperation in social interactions. From an ethnographic perspective, Lohman (2007) provided a detailed description of the role of dreams in shaping cultural and social interactions in a variety of traditional cultures in the modern world. This “facilitates some vital communicative goal of the dreamer” (p. 30). Issues: The decreasing coherence of the field identified in the meeting description indeed is a real and difficult problem. Given these risky and costly characteristics, McNamara posited that REM serves an important function: “I argue that serious consideration of the costs associated with REM might help us identify its benefits and therefore its adaptive functions” (p. 10).
