Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misinformation about evolution persist. Pop science fiction has led a lot of people to believe that biologists aren't believers in evolution. This rich Web site – companion to the PBS series – provides teachers with materials that promote evolution education and help avoid the kinds of myths that make it difficult to understand. discover here laid out in a nested “bread crumb” format to facilitate navigation and orientation. Definitions It's difficult to properly teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. This is particularly relevant when it comes to the meaning of the words themselves. As such, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site is both an accompaniment to the 2001 series, and also a resource on its own. The material is presented in a nested fashion that assists in navigation and orientation. The site defines terms such as common ancestor and the gradual process. These terms help frame the nature of evolution and its relationship to evolution to other concepts in science. The site also provides an overview of how the concept of evolution has been tested and confirmed. This information will help to dispel the myths that are created by the creationists. It is also possible to get a glossary of terms 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. Organisms that have better-adapted traits are more likely than those with less adapted characteristics to survive and reproduce. Common ancestor (also called common ancestor): The most recent ancestral ancestor shared by two or more species. By analyzing the DNA from these species, it is possible to determine the common ancestor. Deoxyribonucleic Acid: A massive biological molecular that holds the necessary information for cell replication. The information is contained in a sequence of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the reason behind the creation of new genetic information within cells. Coevolution is a relationship between two species, where the evolutionary changes of one species influence evolutionary changes in the other. Coevolution is evident in the interactions between predator and prey, or parasites and hosts. Origins Species (groups of individuals that are able to interbreed) change through natural changes in the characteristics of their offspring. The changes can be caused by a variety of factors, including natural selection, genetic drift and mixing of genes. The development of a new species could take thousands of years, and the process may be slowed down or accelerated by environmental factors like climate change or the competition for food or habitat. The Evolution site traces through time the emergence of various animal and plant groups, focusing on major transitions within each group's past. It also examines the evolution of humans as a subject that is particularly important for students. Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans were discovered. One of them was the infamous skullcap and bones that were discovered in 1856 in 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, a year after the publication of the first edition of The Origin. While the site is focused on biology, it includes a good deal of information on geology and paleontology. The website has a number of aspects that are quite impressive, such as an overview of the way that climate and geological conditions have changed over time. It also has maps that show the locations of fossil groups. Although the site is a companion to a PBS television series however, it can stand on its own as an excellent source for teachers and students. The site is well-organized and provides easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized features of the museum website. These hyperlinks make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are hyperlinks to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life has led to many species of animals, plants and insects. Paleobiology, the study of these creatures in their geological environment offers many advantages over modern observational or research methods for exploring evolutionary processes. Paleobiology is able to study not only processes and events that take place frequently or over time, but also the distribution and frequency of different groups of animals in space throughout geological time. The website is divided into several optional pathways to understanding evolution, including “Evolution 101,” which takes the viewer on a line through the scientific process and the evidence supporting the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought. Each of the other sections of the Evolution site is equally well constructed, with materials that can be used to support a range of educational levels and pedagogical styles. In addition to the standard textual content, the site also has an array of multimedia and interactive resources, such as video clips, animations, and virtual labs. The content is laid out in a nested bread crumb fashion that aids navigation and orientation on the web site. For instance, the page “Coral Reef Connections” provides a comprehensive overview of the relationships between corals and their interactions with other organisms. It then concentrates on a specific clam that can communicate with its neighbors and respond to changes in water conditions 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 broad range of topics in evolutionary biology. The content also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis, which is a key tool for understanding the evolution of change. Evolutionary Theory For biology students evolution is a crucial thread that binds all the branches of the field. A wide selection of resources helps teachers teach evolution across all disciplines of life science. One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that provides depth and breadth in its educational resources. The site features a wide range of interactive learning modules. It also has an encased “bread crumb” structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. Animation that introduces the concept of genetics, which links to a page about John Endler's artificial-selection experiments with guppies on native ponds in Trinidad. The Evolution Library on this website contains a large multimedia library of resources that are associated with evolution. The content is organized according to curricula-based paths that correspond to the learning goals set forth in the biology standards. It includes seven short videos specifically designed for use in classrooms. They can be viewed online or purchased as DVDs. Evolutionary biology is still an area of study that poses many important questions, such as what triggers evolution and the speed at which it happens. This is especially true in the case of human evolution, where it was difficult to reconcile religious beliefs that held that humanity has a special place in creation and a soul, with the notion that our physical traits originated from the apes. There are 에볼루션바카라사이트 of other ways evolution can take place, with natural selection as the most widely accepted theory. Scientists also study other kinds such as genetic drift and sexual selection. While many scientific fields of study conflict with literal interpretations in religious texts, the concept of evolution biology has been the subject of intense debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, others aren't.
