Evolution Site – Teaching About Evolution Despite the best efforts of biology teachers, misinformation about evolution persist. People who have been exposed to pop science nonsense often assume that biologists are saying they do not believe in evolution. This rich website – companion to the PBS series – provides teachers with materials that support evolution education and help avoid the kinds of misinformation that can hinder it. It's organized in a nested “bread crumb” format for ease of navigation and orientation. Definitions Evolution is a complex and difficult subject matter to teach well. It is often misunderstood by non-scientists, and even some scientists are guilty of using an interpretation that is confusing the issue. This is particularly applicable to debates about the meaning of the word itself. It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful way. The website is a companion to the show which first aired in 2001, but is also an independent resource. The material is presented in a nested fashion that assists in navigation and orientation. The site defines terms such as common ancestor, the gradual process and adaptation. These terms help to define the nature and significance of evolution to other concepts in science. The site gives a comprehensive overview of the way in which evolution has been examined. This information can help dispel myths created by creationists. You can also access a glossary that contains terms used in evolutionary biology. These terms include: Adaptation: The tendency of hereditary traits to become more suited to a particular environment. This is a result of natural selection. Organisms with better-adapted traits are more likely than those with less adaptable traits to reproduce and survive. Common ancestor: The most recent common ancestor of two or more different species. The common ancestor can be identified by analyzing the DNA of the species. Deoxyribonucleic Acid: A huge biological molecular that holds the information needed for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are the basis for new genetic information within cells. Coevolution is a relationship between two species in which the evolution of one species are influenced by evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey or parasite and host. Origins Species (groups which can interbreed) change by a series of natural variations in their offspring's traits. 에볼루션사이트 can be caused by a variety of causes such as natural selection, genetic drift, and gene pool mixing. The evolution of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food and habitat can slow or speed up the process. The Evolution site tracks the development of a number of different groups of animals and plants over time, focusing on the major transitions that occurred in the history of each group. It also focuses on the human evolutionary roots, a topic that is especially important for students to understand. Darwin's Origin was written in 1859, when just a few antediluvian fossils of human beings had been discovered. The most famous among them was the skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, one year following the initial edition of The Origin. Origin. While the site is focused on biology, it also offers a lot of information on geology and paleontology. The Web site has several aspects that are quite impressive, such as the timeline of how geological and climate conditions have changed over the course of time. 에볼루션사이트 features a map showing the distribution of fossil groups. Although the site is a companion to a PBS television show, it also stands on its own as an excellent resource for teachers and students. The site is well-organized and offers easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features of the museum website. 무료 에볼루션 help users move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also links to John Endler's experiments with guppies that illustrate the importance ecology in evolutionary theory. Diversity The evolution of life has produced an array of animals, plants and insects. Paleobiology is the study of these creatures in their geological environment offers many advantages over modern observational or experimental methods of studying evolutionary processes. In addition to examining the processes and events that happen regularly or over a long period of time, paleobiology is able to analyze the relative abundance of different groups of organisms and their distribution throughout geological time. The site is divided into several paths that can be chosen to study the subject of evolution. One of the paths, “Evolution 101,” takes the viewer through the complexities and evidence of evolution. The path also explores misconceptions about evolution as well as the history of evolutionary thought. Each of the other major sections of the Evolution site is equally well developed, with materials that support a variety of educational levels and pedagogical styles. The site offers a wide array of interactive and multimedia resources which include videos, animations, and virtual laboratories in addition to general textual content. The breadcrumb-like structure of the content assists with navigation and orientation on the massive website. For example the page “Coral Reef Connections” gives a brief overview of coral relationships and their interaction with other organisms. It then narrows down to a single clam that is able to communicate with its neighbors and respond to changes in water conditions that take place at the level of the reef. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a wide variety of topics in evolutionary biology. The material also provides an explanation of the role of natural selection and the concept of phylogenetic analysis, which is an important tool in understanding evolutionary change. Evolutionary Theory Evolution is an underlying thread that runs through all branches of biology. A vast collection of resources helps teachers teach about evolution across all life sciences. One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that offers both the depth and breadth of its educational resources. The site has a variety of interactive learning modules. It also features an “bread crumb structure” that assists students in moving away from the cartoon-like style of Understanding Evolution and onto elements of this vast website that are closely linked to the fields of research science. An animation that introduces students to the concept of genetics, which links to a page highlighting John Endler's artificial-selection experiments with guppies on native ponds in Trinidad. Another useful resource is the Evolution Library on this website, which includes an extensive library of multimedia resources that are related to evolution. The contents are organized into curriculum-based paths that parallel the learning objectives set out in the biology standards. It includes seven short videos specifically designed for use in classrooms, and can be streamed for no cost or purchased on DVD. Evolutionary biology remains a field of study that has many important questions to answer, such as what triggers evolution and the speed at which it happens. This is particularly true for human evolution, where it has been difficult to reconcile the notion that the physical characteristics of humans were derived from apes, and the religions that believe that humanity is unique among living things and holds a an enviable place in creation with soul. Additionally there are a myriad of ways that evolution could be triggered with natural selection being the most widely accepted theory. However scientists also study other kinds of evolution like genetic drift, mutation, and sexual selection, among others. Many fields of inquiry are in conflict with literal interpretations of the Bible Evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, others haven't.
