Evolution Site – Teaching About Evolution Despite the best efforts of biology teachers, there are still misconceptions about the evolution. People who have absorbed the nonsense of pop science often believe that biologists claim they don't believe in evolution. This rich Web site – companion to the PBS series – provides teachers with materials that support evolution education and help avoid the kinds of misinformation that can make it difficult to understand. It's organized in a “bread crumb” format to facilitate navigation and orientation. Definitions It's difficult to properly teach evolution. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is especially relevant to discussions about the nature of the word. As such, it is essential to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The website is a companion to the series that first aired in 2001, but is also an independent resource. The information is presented in an organized manner that makes it simpler to navigate and comprehend. The site defines terms like common ancestor, gradual process and adaptation. 에볼루션 슬롯게임 help to define the nature of evolution as well as its relation to other scientific concepts. The site gives a comprehensive overview of the ways that evolution has been examined. This information can help dispel myths created by creationists. It is also possible to find a glossary of terms used in evolutionary biology. These terms include: Adaptation is the process of changing 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 adaptable characteristics to survive and reproduce. Common ancestor (also called common ancestor) is the most recent ancestor 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 required for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells. Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution is evident in the interactions between predator and prey, or parasite and hosts. Origins Species (groups that can interbreed) change by a series of natural variations in the traits of their offspring. These changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of a new species may 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 tracks through time the emergence of various groups of animals and plants with a focus on major changes in each group's past. It also focuses on the evolutionary origin of humans which is particularly important for students to understand. When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year before the first edition of the Origin was published, it's very unlikely that Darwin had ever heard of it. While the site is focused on biology, it also contains a wealth of information about geology as well as paleontology. The site offers several features that are particularly impressive, such as a timeline of how climate and geological conditions have changed over the course of time. It also has a map showing the distribution of fossil groups. The site is a companion for the PBS television series, but it could also be used as a resource by teachers and students. The site is well-organized and provides easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features of the museum's website. These hyperlinks make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are hyperlinks to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures within their geographical context and offers numerous advantages over modern observational and experimental methods of examining evolutionary processes. In addition to examining processes and events that occur frequently or over a long period of time, paleobiology can be used to analyze the diversity of species of organisms and their distribution in space over geological time. The Web site is divided into various pathways to understanding evolution, including “Evolution 101,” which takes the user on a linear path through the nature of science and the evidence to support the theory of evolution. The path also explores misconceptions regarding evolution, as well as the history of evolutionary thought. Each of the main sections on the Evolution website is equally well-developed, and includes materials that are suited to a variety of curriculum levels and teaching styles. In addition to the general textual content, the site offers an extensive selection of multimedia and interactive resources including videos, animations and virtual laboratories. The breadcrumb-like organization of the content assists with navigation and orientation on the massive Web site. For example, 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 that take place at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, offers a great introduction to the many areas of evolutionary biology. The content also includes an explanation of the importance of natural selection and the concept phylogenetics analysis as a key method for understanding the evolution of change. Evolutionary Theory Evolution is a common thread that connects all branches of biology. A vast collection of resources helps teachers teach about evolution across the life sciences. One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that offers both depth and a variety of educational resources. The site has a variety of interactive learning modules. It also features an “bread crumb structure” that allows students to move away from the cartoon style used in Understanding Evolution and onto elements on this site that are more closely related to the worlds of research science. An animation that introduces students to the concept of genetics, which links to a page that highlights John Endler's artificial-selection experiments with 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 in curriculum-based pathways that correspond to the learning goals set forth in biology standards. It contains seven short videos specifically designed for classroom use. They can be viewed online or purchased as DVDs. A variety of crucial questions remain in the midst of evolutionary biology, including what triggers evolution and how fast it occurs. This is particularly relevant to human evolution, where it's been difficult to reconcile the notion that the physical traits of humans derived from apes with religious beliefs that hold that humanity is unique among living things and holds a an exclusive place in the creation. It is a soul. There are also a number 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. Many fields of inquiry have a conflict with literal interpretations of the Bible evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, other religions haven't.
