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 site, which is a companion to the PBS series – provides teachers with materials that support evolution education and avoids the kinds of myths that undermine it. It's organized in a “bread crumb” format to make navigation and orientation easier. Definitions It's difficult to properly teach evolution. It is often misunderstood by non-scientists and even scientists use a definition that confuses the issue. This is especially relevant to discussions on the definition of the word itself. Therefore, it is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The website is a companion to the show which first aired in 2001, but also functions as an independent resource. The material is presented in a way which aids navigation and orientation. The site defines terms such as common ancestor and gradual process. These terms help to define the nature and significance of evolution to other scientific concepts. The site provides an overview of the way in which evolution has been examined. This information can help dispel myths that are created by the creationists. It is also possible to access the glossary of terms used in evolutionary biology. These terms include: The process of adaptation is the tendency of hereditary traits to become more suitable to their environment. This is a result of natural selection. Organisms with more adaptable traits are more likely than those with less-adapted traits to reproduce and survive. Common ancestor: The most recent common ancestor of two or more distinct species. By analyzing DNA from these species it is possible to determine the common ancestor. Deoxyribonucleic Acid: A massive biological molecular containing the information required for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form long chains, also known as chromosomes. Mutations are responsible for the creation of new genetic information within cells. Coevolution: A relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be seen through the interaction between predator and prey, or parasite and hosts. Origins Species (groups which can interbreed) develop by a series of natural variations in their offspring's traits. The changes can be caused by a variety of causes such as natural selection, genetic drift, and mixing of gene pools. The evolution of new species could take thousands of years. Environmental circumstances, such as changes in the climate or competition for food and habitat, can slow or accelerate the process. The Evolution site tracks the development of various animal and plant groups through time, focusing on the major shifts that occurred throughout each group's history. It also focuses on human evolution and is a subject of particular importance to students. Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of human beings had been discovered. The famous skullcap, along with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was published in 1858, one year after the first edition of The Origin. Origin. The site is primarily a biology site however, it also has a lot of information on paleontology and geology. The website has numerous aspects that are quite impressive, such as a timeline of how geological and climate conditions have changed over the course of time. It also features an interactive map that shows the location of fossil groups. Although the site is a companion to a PBS television series, it also stands on its own as a valuable resource for teachers and students. The site is well organized and provides clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized components of the museum's Web site. These hyperlinks make it easy to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. In particular, there are links to John Endler's research with Guppies, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has resulted in a variety of animals, plants, and insects. Paleobiology is the study of these creatures within their natural environment is a superior method of study over modern observational or research methods for studying evolutionary phenomena. Paleobiology can examine not only processes and events that take place frequently or over time, but also the distribution and frequency of different groups of animals across geological time. The website is divided into various options to gain knowledge about evolution. One of these paths, “Evolution 101,” walks the reader through the evolution of nature and the evidence of evolution. The course also focuses on misconceptions about evolution as well as the history of evolutionary thinking. Each of the main sections on the Evolution website is equally well-developed, with materials that are suited to a variety of levels of curriculum and teaching methods. In addition to the general textual content, the site features an array of multimedia and interactive resources, such as video clips, animations, and virtual labs. The breadcrumb-like arrangement of the content helps with navigation and orientation on the large website. For instance, the page “Coral Reef Connections” provides an overview of coral relationships and their interactions with other organisms, then zooms in on a single clam that is able to communicate with its neighbors and respond to changes in the water conditions at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages, offers a great introduction to many topics in evolutionary biology. The content also includes a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a crucial method to understand evolutionary change. Evolutionary Theory For biology students, evolution is a key thread that weaves together all the branches of the field. A vast collection of books helps in teaching evolution across the life science disciplines. One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that offers both depth and a variety of educational resources. The site features a wide range of interactive learning modules. It also has a nested “bread crumb” structure that helps students move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the field of research science. 에볼루션 사이트 that introduces students to the concept of genetics links to a page highlighting John Endler's experiments in artificial selection using guppies on native ponds in Trinidad. The Evolution Library on this website has a huge multimedia library of materials that deal to evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives set out in the biology standards. It contains seven short videos specifically designed for use in classrooms. They can be streamed or purchased as DVDs. Evolutionary biology is an area of study that poses many important questions, including what triggers evolution and how quickly it takes place. This is particularly true in the case of human evolution, where it was difficult to reconcile religious beliefs that held that humanity has a unique place in the creation and a soul, with the notion that our physical traits originated from the apes. There are also a number of other ways in which evolution can occur and natural selection being the most well-known theory. Scientists also study other types such as genetic drift, and sexual selection. Many fields of inquiry conflict with the literal interpretations of the Bible evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolution, while others haven't.
