Behaving Brain 1. Explain the major concepts of evolutionary theory, such as natural selection and variation. Charles Darwin created the theory of evolution and helped us to understand the roots of behavior and mental process. Natural selection states: variations increasing that odds of reproducing and surviving are most likely to be passed on to future generations, this has shaped our traits and behavior tendencies. Nature has selected advantageous variations from the mutations and new gene combo's produced at each human understanding.
Nurture on the other hand is a view, is a view proposed by the social approach suggesting that behavior is affected by socialization and environment. The natural and sexual selection in the evolutionary approach are two important factors to account for the survival of the fittest. When there is a change in the environment, a danger, a situation which needs quick adaptation to survive, the individuals who adapt the fastest and the better are the ones to survive and therefore to pass on their genes onto the next generation. The individuals that fail to adapt die, and their genetic makeup is lost. In the sexual selection, individuals from every sex have genes, which provide them with attractive characteristics to attract the
Chapter 7 study guide Adaptation is a structure, behaviour and phsyclogical process that helps the organism survive and reproduce in a particular environment. Camouflage and mimicry are the examples of structural adaptation. Mimcry is a structural adaptation in which a harmless species resembles a harmful species in the coloration or structure. The changes in characteristics are the result of random, heritable mutations in genetic material that accumulate over generations. Environmental conditions determine whether a variation in an individual has a positive or negative effect, or no effect on the individual’s ability to survive and reproduce.
Her analysis suggests that it is the knowledge and acceptance of otherness what helps the relationship between two different races achieve new evolutionary level of social and biological symbiosis. Hardy argues that in order to understand the complex relationship between both species and the psychological impact that it has on both of them, the readers must first examine complex Talic and Terran’s arrangement. She opens her essay quoting Butler’s afterword to “Bloodchild” where Butler presents the picture of the utopian society. According to Butler, Hardy says, humans will eventually encounter an alien live form and they will have to make certain adaptations and unusual sacrifices in order to survive and preserve humanity. In “Bloodchild” Butler speaks of the adolescent boys carrying the eggs of insect aliens as the part of agreement between both species.
Did the phylogenies of the different islands support the theory of one colonization followed by adaptive radiation and convergent evolution? Yes | 1. How did one species produce so many different species (the six ecomorphs)? The need to survive in different areas. | 1.
In his opinion, college students should try to find evidence, investigate, and speculate differently about the material they have learned. “In other word college deals with the rational justification of belief” (Meiland). Also college professors should present and examine the basis of the material in order to give basic information to the students. Meiland says “college simply reflects the legitimation of belief by inquiring into the rationality of every belief to find out whether each belief is supported by good reasons”( Meiland). He wants college students to keep
03-27-2012 Extra Credit: Response to Robert Krueger's Talk Robert Krueger's presentation, “Understanding genetic and environmental contributions to individual differences: Contemporary findings and challenges”, looked at different factors contributing to personality and psychopathological tendencies. Krueger started out his presentation explaining Genome-Wide Association studies (GWAS). He was excited by the new technology that allows researchers to quickly analyze whole genome samples at a high resolution for genetic variation. He claimed that research show genes only vary slightly among individuals. Krueger then discussed twin studies and other methods commonly used to tap into that variation.
Chapter 13 Learning Objectives Define Adaptations Something, such as a device or mechanism, that is changed or changes so as to become suitable to a new or special application or situation. Evolution Change in the genetic composition of a population during successive generations, as a result of natural selection acting on the genetic variation among individuals, and resulting in the development of new species. Fossils are any preserved remains or imprints of living organisms (usually ancient animals and plants), such as bones, shells, footprints, or leaf impressions. Who was Charles Darwin, what was the name of the ship that he sailed on, and what is the name of his 1859 publication? The beagle, Explain the importance of the following people: Jean Baptiste Lamarck French biologist.
Sometimes the same species have different colours to better blend into their habitat (Forkner, and Hunter, 2000). According to Robinson and Holmes, (2006) who termed adaptation as A trait (structure or behavior) that has changed over time to make an organism better suited to survive and reproduce in its environment. The theory of natural selection when observed using a real life situation it could be exhausting and take years to gather enough information to depict what happens in real life. Therefore a theory of natural selection can be tested and observed using a model system to see what can happen in a real world. By using a model system is appropriate as one can predict what will happen in a short period of time.
Introduction State what you are doing in the essay This response will attempt to uncover the assumptions and interrelationships of the evolutionary explanation for emotion, in particular, disgust. Define evolution Evolution is the changing in the inherited traits of a species over time. Describe the theory of evolution Evolutionary psychology is at the biological level of analysis and aims to explain all behaviour by evolutionary means. Charles Darwin – the father of evolutionary psychology – proposed the theory of evolution. He suggested those who adapt best to environmental challenges will have a greater chance of survival, reproduction, and passing on genes.
