Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions persist regarding evolution. Pop science nonsense has led people to believe that biologists aren't believers in evolution. This rich Web site – companion to the PBS series It provides teachers with materials which support evolution education and avoid the kinds of misconceptions that make it difficult to understand. It's organized in a “bread crumb” format to facilitate navigation and orientation. Definitions It's difficult to effectively teach evolution. It is often misunderstood by non-scientists and even some scientists are guilty of using definitions that confuse the issue. This is particularly true when it comes to discussions about the meaning of the word itself. Therefore, it is essential to define terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a simple and efficient way. The site serves as an accompanying site for the 2001 series, and also a resource on its own. The content is presented in a nested manner which aids navigation and orientation. The site defines terms such as common ancestor, gradual process and adaptation. These terms help to frame the nature of evolution as well as its relation to other scientific concepts. The site gives a comprehensive overview of the ways in which evolution has been tested. This information will help to dispel the myths created by creationists. It is also possible to get a glossary of terms used in evolutionary biology. These terms include: Adaptation: The tendency of hereditary traits to become more adaptable to a specific environment. This is the result of natural selection. It occurs when organisms with better-adapted traits are more likely to survive and reproduce than those with less adaptable characteristics. Common ancestor (also known as common ancestor) is the most recent ancestor that is shared by two or more species. The common ancestor can be identified through analyzing the DNA of the species. Deoxyribonucleic acid: A huge biological molecule that contains the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to 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 are influenced evolutionary changes of the other. Examples of coevolution include the interactions between predator and prey or the parasite and the host. Origins Species (groups that can crossbreed), evolve by a series of natural variations in their offspring's traits. Changes can be caused by various factors, including natural selection, gene drift and mixing of the gene pool. The development of new species can take thousands of years. 에볼루션 무료 바카라 , like changes in the climate or competition for food resources and habitat can slow or speed up the process. The Evolution site tracks through time the evolution of various groups of animals and plants, focusing on major transitions in each group's history. It also examines the human evolutionary roots, a topic that is particularly important for students to know. When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. One of them was the infamous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was one year before the first edition of the Origin was published, it is highly unlikely that Darwin had seen or heard of it. The site is mostly one of biology however, it also has a lot of information on geology and paleontology. The most impressive features of the website are a timeline of events which show how geological and climatic conditions have changed over time as well as an interactive map of the distribution of a few of the fossil groups featured on the site. The site is a companion to the PBS TV series but it could also be used as a resource for teachers and students. The site is extremely well organized and provides clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler’s experiments with guppies that illustrate the importance of ecology in evolutionary theory. Diversity The evolution of life has resulted in a variety of plants, animals and insects. Paleobiology is the study of these creatures within their geological context offers many advantages over modern observational or experimental methods of studying evolutionary phenomena. In addition to exploring processes and events that occur frequently or over a long period of time, paleobiology is able to examine the relative abundance of different species of organisms and their distribution across geological time. The site is divided into several options to study the subject of evolution. One of these paths, “Evolution 101,” walks the reader through the nature and evidence of evolution. The path also explores common misconceptions about evolution and the evolution theory's history. Each of the other main sections of the Evolution site is similarly created, with resources that support a variety of different pedagogical levels and curriculum levels. In addition to the general textual content, the site offers a wide range of multimedia and interactive content including video clips, animations, and virtual labs. The content is organized in a nested, bread crumb fashion that aids navigation and orientation within the large web site. The page “Coral Reef Connections”, for example, provides a comprehensive overview of the coral's relationships and interactions with other organisms, and then zooms in on one clam that is able communicate with its neighbors and respond 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, offer an excellent introduction to a wide spectrum of topics in evolutionary biology. The material also provides an overview of the importance of natural selection as well as the concept of phylogenetic analysis, which is a key method to understand evolutionary changes. Evolutionary Theory For biology students the concept of evolution is a major thread that connects all branches of the field. A vast collection of books helps in teaching evolution across all disciplines of life science. One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that offers both depth and breadth in its educational resources. The site offers a variety of interactive learning modules. It also has an “bread crumb structure” that assists students in moving away from the cartoon-like style that is used in Understanding Evolution and onto elements of this vast website that are closely linked to the fields of research science. For example an animation that explains the concept of genetic inheritance links to a page that highlights John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad. Another resource that is worth mentioning is the Evolution Library on this Web site, which has an extensive library of multimedia items related to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning goals set forth in the standards for biology. It contains seven videos designed specifically for use in classrooms, and can be streamed for no cost or purchased on DVD. A number of important questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it happens. This is particularly relevant in the case of human evolution, where it was difficult to reconcile religious beliefs that held that humans have a distinct position in the universe and a soul, with the idea that innate physical traits originated from apes. There are also a number of other ways evolution can take place including natural selection, which is the most well-known theory. However scientists also study other kinds of evolution like mutation, genetic drift and sexual selection, among other things. Although many scientific fields of study are in conflict with literal interpretations in religious texts, the concept of evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, but others haven't.
