Evolution Site – Teaching About Evolution Despite the best efforts of biology teachers, misinformation about evolution remain. 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 that support evolution education and avoids the kinds of myths that hinder it. It's organized in a nested “bread crumb” format for ease of navigation and orientation. Definitions Evolution is a complex and challenging subject to teach effectively. Non-scientists often misunderstand the subject and some scientists use a definition which confuses it. This is especially true when discussing the nature of the words themselves. It is therefore crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. The site is both a companion for the 2001 series, but also a resource on its own. The material is presented in a nested fashion which aids navigation and orientation. The site defines terms like common ancestor (or common ancestor), gradual process, and adaptation. These terms help frame the nature of evolution and its relationship to evolution to other concepts in science. The site provides an overview of the ways in which evolution has been examined. This information can be used to dispel misconceptions that have been propagated by creationists. It is also possible to get a glossary of terms used in evolutionary biology. These terms include: The process of adaptation is the tendency of heritable traits to become more suitable to their environment. This is due to natural selection. It occurs when organisms that are more adaptable traits are more likely to survive and reproduce than those with less adapted traits. 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 large biological molecular that contains the information needed for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are the source of new genetic information in cells. Coevolution is a relationship between two species in which 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 that can interbreed) change by a series of natural variations in their offspring's traits. Read Significantly more can be triggered by a variety of factors, including 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 accelerate the process. The Evolution site tracks the development of a number of different animal and plant groups through time and focuses on the most significant changes that took place in the evolution of each group's history. It also explores human evolution and is a subject of particular importance to students. When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was a year before the first edition of the Origin was published, it is highly unlikely that Darwin had heard or seen of it. While the site is focused on biology, it includes a good deal of information about geology and paleontology. The site offers several features that are especially impressive, including a timeline of how geological and climate conditions have changed over time. It also has a map showing the distribution of fossil groups. The site is a companion to a 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 introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler’s experiments with guppies, which illustrate the importance ecology in evolutionary theory. 에볼루션사이트 of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures in their geological context and has a number of advantages over the current observational and experimental methods for analyzing evolutionary processes. Paleobiology can examine not only processes and events that happen regularly or over time, but also the relative abundance and distribution of various animal groups across the geological time. The site is divided into different routes that can be taken to study the subject of evolution. One of the paths, “Evolution 101,” walks the reader through the complexities and evidence of evolution. The path also reveals common misconceptions about evolution as well as the evolution of thought. Each of the main sections on the Evolution website is equally well-developed, and includes materials that can be used to support a variety of curriculum levels and teaching styles. In addition to the general textual content, the site features a wide range of multimedia and interactive resources, such as video clips, animations, and virtual labs. The content is presented in a nested bread crumb fashion that aids navigation and orientation within the vast web site. For instance, the page “Coral Reef Connections” gives a brief overview of coral relationships and their interaction with other organisms, then zooms in on a single clam that can communicate with its neighbors and respond to changes in water conditions at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages gives a good introduction to a variety of topics in evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a crucial tool in understanding evolutionary changes. Evolutionary Theory Evolution is an underlying thread that runs through all branches of biology. A rich collection supports teaching evolution across all life science disciplines. One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that provides the depth and breadth of its educational resources. The site offers a range of interactive learning modules. It also features an “bread crumb structure” that allows students to move away from the cartoon-like style of Understanding Evolution and onto elements of this vast website that are closely related to the fields of research science. For instance an animation that introduces the concept of genetic inheritance links to a page that focuses on John Endler's experiments in artificial selection with guppies in native ponds of Trinidad. The Evolution Library on this website has a huge multimedia library of resources that are associated with evolution. The content is organized into curriculum-based paths that parallel the learning objectives outlined in the biology standards. It includes seven short videos designed for use in classrooms. These can be viewed online or purchased as DVDs. A variety of crucial questions remain in the midst of evolutionary biology, including what causes evolution to occur and how fast it occurs. This is particularly relevant for humans' evolution, where it was difficult to reconcile religious beliefs that held that humans have a distinct place in creation and a soul with the notion that our physical traits were derived from apes. There are a myriad of other ways evolution can take place and natural selection being the most well-known theory. However scientists also study other kinds of evolution, such as genetic drift, mutation, and sexual selection, among other things. Although many scientific fields of study are in conflict with literal interpretations found in religious texts, the concept of evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the ideas of evolution, others aren't.
