에볼루션 – Teaching About Evolution Despite the best efforts of biology educators, there are still a lot of misconceptions about the evolution. Pop science nonsense has led people to believe that biologists aren't believers in evolution. This site, a companion to the PBS program offers teachers resources that support the evolution of education while avoiding the types of misconceptions which undermine it. It's arranged in a nested “bread crumb” format to make it easy for navigation and orientation. Definitions Evolution is a complicated and difficult subject to teach well. 에볼루션 바카라사이트 is often misunderstood even by non-scientists, and even scientists have been guilty of using a definition that confuses the issue. This is especially relevant when discussing the meaning of the words themselves. It is essential to define terms used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient way. The site is both a companion for the 2001 series, but also a resource of its own. The material is presented in a structured way that makes it easy to navigate and comprehend. The site defines terms like common ancestor, gradual process and adaptation. These terms help to define the nature of evolution as well as its relationship to other concepts in science. The website provides a summary of the way the concept of evolution has been tested. This information can help dispel the myths created by creationists. You can also access a glossary that includes terms that are used in evolutionary biology. These terms include: Adaptation is the process of changing hereditary traits to become better suited to an environment. This is the result of natural selection, which occurs when organisms that have more adaptable characteristics are more likely to survive and reproduce than those with less adaptable traits. Common ancestor (also called common ancestor): The most recent ancestral ancestor shared by two or more species. The common ancestor can be identified by analyzing the DNA of the species. Deoxyribonucleic Acid: A huge biological molecular that contains the information needed for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are the source of new genetic information in cells. Coevolution is the relationship between two species in which the evolution of one species influence evolutionary changes in the other. Coevolution can be observed through the interaction between predator and prey, or parasite and hosts. Origins Species (groups of individuals that can interbreed) evolve through an array of natural changes in the characteristics of their offspring. Changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, such as climate changes or competition for food or habitat can impede or accelerate the process. The Evolution site tracks the evolution of a number of different animal and plant groups through time with a focus on the key transitions that occurred in the evolution of each group's history. It also focuses on human evolution as a subject that is of particular interest to students. Darwin's Origin was written in 1859, when just a few antediluvian fossils of human beings had been discovered. Among them was the famous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap when it was published in 1858, a year following the initial edition of The Origin. While the site focuses on biology, it includes a good deal of information on geology and paleontology. The most impressive features on the site are a timeline of events which show how climatic and geological conditions have changed over time and an outline of the distribution of some fossil groups listed on the site. Although the site is a companion to a PBS television series however, it can stand on its own as a great resource for teachers and students. The site is well-organized, and provides easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features on the museum's website. These links make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler’s experiments with guppies. They illustrate the importance ecology in evolutionary theory. Diversity The evolution of life has resulted in an array of animals, plants and insects. Paleobiology is the study of these creatures within their natural environment and has numerous advantages over the modern observational and research methods for analyzing evolutionary phenomena. Paleobiology can examine not only the process and events that happen regularly or over time, but also the relative abundance and distribution of different species of animals across geological time. The site is divided into a variety of pathways to understanding evolution, including “Evolution 101,” which takes the viewer on a liner path through the nature of science and the evidence to support the theory of evolution. The path also explores the most common misconceptions about evolution, as well as the history of evolutionary thought. Each of the other main sections of the Evolution site is similarly developed, with materials that can be used to support a range of educational levels and pedagogical styles. In addition to the general textual content, the site offers an array of interactive and multimedia resources, such as videos, animations and virtual laboratories. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the vast web site. The page “Coral Reef Connections”, for example, gives a brief overview of the coral's relationships, their interaction with other organisms and is enlarged to show a single clam, which can communicate with its neighbors and react to changes in conditions of the water at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a wide variety of topics in evolutionary biology. The material includes a discussion on the role of natural selectivity and the concept phylogenetics analysis which is a crucial method for understanding the evolution of change. Evolutionary Theory For biology students, evolution is a key thread that binds all branches of the field. A vast collection of resources helps teachers teach about evolution across the life sciences. One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both the depth and breadth of its educational resources. The site features a wealth of interactive learning modules. It also features an “bread crumb structure” that helps students move away from the cartoon style used in Understanding Evolution and onto elements of this vast website that are closely linked to the realms of research science. For instance an animation that introduces the concept of genetic inheritance links to a page that focuses on John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad. The Evolution Library on this website is a vast multimedia library of resources that are associated to evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives set out in the standards for biology. It contains seven short videos designed for classroom use. These can be viewed online or purchased as DVDs. Evolutionary biology is still an area of study with a lot of important questions, such as what triggers evolution and how quickly it takes place. This is particularly applicable to human evolution which has made it difficult to reconcile that the physical characteristics of humans were derived from apes with religious beliefs that claim that humanity is unique among living things and holds a a special place in creation. It is soul. In addition there are a myriad of ways that evolution can be triggered and natural selection is the most widely accepted theory. However scientists also study different types of evolution such as mutation, genetic drift and sexual selection, among other things. While many scientific fields of study conflict with literal interpretations found in religious texts, the concept of evolution biology has been a subject of intense debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs to evolution while others haven't.
