Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions persist about the evolution. Pop science nonsense has led many people to believe that biologists aren't believers in evolution. This rich website – companion to the PBS series It provides teachers with materials which support evolution education and help avoid the kinds of myths that undermine it. It's laid out in a nested “bread crumb” format to facilitate navigation and orientation. Definitions It's not easy to effectively teach evolution. It is often misunderstood by non-scientists and even some scientists have been guilty of using definitions that confuse the issue. This is particularly relevant when it comes to the nature of the words themselves. As such, it is essential to define terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful way. The site is a companion to the show which first aired in 2001, but also functions as an independent resource. The information is organized in a way that makes it easy to navigate and comprehend. The site defines terms such as common ancestor, gradual process and so on. These terms help frame the nature and relationship of evolution with other scientific concepts. The website provides a summary of the manner the concept of evolution has been examined. This information can be used to dispel myths that have been propagated by creationists. You can also access a glossary that includes terms used in evolutionary biology. These terms include: Adaptation is the tendency of heritable traits to be better suited to an environment. This is a result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted traits to survive and reproduce. Common ancestor (also known as common ancestor): The most recent ancestor shared by two or more species. By analyzing DNA from these species, it is possible to identify the common ancestor. Deoxyribonucleic acid: A huge biological molecule that contains the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the cause of new genetic information within cells. Coevolution is the relationship between two species, where the evolution of one species are influenced by evolutionary changes of the other. Coevolution is evident through the interaction between predator and prey, or parasite and hosts. Origins Species (groups of individuals that can interbreed) develop through natural changes in the characteristics of their offspring. Changes can be caused by many factors, such as 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 change or competition for food or habitat can slow or speed up the process. The Evolution site tracks the evolution of a variety of groups of animals and plants over time, focusing on the major shifts that occurred throughout the history of each group. It also explores human evolution, which is a topic that is of particular interest for students. Darwin's Origin was written in 1859, when only a few antediluvian fossils of human beings had been discovered. The skullcap that is famous, along with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as 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 extremely unlikely that Darwin had heard or seen of it. While the site focuses on biology, it offers a lot of information about geology and paleontology. One of the most appealing features of the Web site are a timeline of events that show how geological and climatic conditions changed over time, and an interactive map of the distribution of a few of the fossil groups featured on the site. The site is a companion for the PBS television series, but it could also be used as a source for teachers and students. The site is very well-organized and has clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum Web site. These links facilitate the transition from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are 에볼루션 슬롯게임 to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has led to a wide variety of plants, animals, 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 focuses on not only processes and events that happen regularly or over time but also the distribution and frequency of different species of animals across geological time. The Web site is divided into various ways to learn about evolution, including “Evolution 101,” which takes the viewer on a line through the nature of science and the evidence to support the theory of evolution. The path also explores common misconceptions about evolution and the evolution of thought. Each of the main sections of the Evolution website is equally well-designed, with materials that are suited to a variety of levels of curriculum and teaching methods. The site includes a variety of multimedia and interactive resources that include videos, animations, and virtual laboratories as well as general textual content. The breadcrumb-like organization of the content assists with navigation and orientation on the vast web site. The page “Coral Reef Connections” For instance, the page “Coral Reef Connections” provides a comprehensive overview of the coral's relationships and interactions with other organisms and zooms in to one clam, which is able communicate with its neighbors and react to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to the broad range of topics in evolutionary biology. The material includes an explanation of the importance of natural selection and the concept of phylogenetics analysis, an important tool to understand evolutionary change. Evolutionary Theory Evolution is an underlying thread that is found throughout all branches of biology. A rich collection of resources helps teachers teach about evolution across the life sciences. One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that provides depth and wide range of educational resources. The site features a wide range of interactive learning modules. It also has a nested “bread crumb” structure that allows students to move from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the field of research science. Animation that introduces the concept of genetics, which links to a page highlighting John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad. The Evolution Library on this website contains a large multimedia library of assets related with evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning objectives outlined in the biology standards. It includes seven short videos specifically intended for use in the classroom. These can be streamed or purchased as DVDs. Evolutionary biology is an area of study that has many important questions, including the causes of evolution and how fast it takes place. This is particularly relevant for the evolution of humans where it was a challenge to reconcile religious beliefs that humanity has a unique place in the creation and a soul, with the idea that innate physical traits originated from Apes. Additionally there are a myriad of ways in which evolution could be triggered and natural selection is the most widely accepted theory. However scientists also study other kinds of evolution, such as mutation, genetic drift and sexual selection, among others. While many fields of scientific inquiry conflict with literal interpretations of the Bible, evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, while others haven't.
