Evolution Site – Teaching About Evolution Despite the best efforts by biology educators, there are still a lot of misconceptions about evolution. People who have absorbed the nonsense of pop science often believe that biologists don't believe in evolution. This site, which is a companion to the PBS program that provides teachers with resources which support evolution education while avoiding the types of misconceptions that can undermine it. It's arranged in a nested “bread crumb” format to make it easy for navigation and orientation. Definitions It's not easy to effectively teach evolution. Non-scientists often misunderstand the subject and some scientists use a definition that confuses it. This is particularly applicable to debates about the meaning of the word itself. It is therefore crucial to define the terms used in evolutionary biology. Understanding Evolution's website does this in a straightforward and useful manner. click through the next webpage is a companion for the 2001 series, and also a resource of its own. The material is organized in a manner that makes it easier to navigate and understand. The site defines terms like common ancestor and the gradual process. 에볼루션 무료체험 help to define the nature of evolution as well as its relation to other scientific concepts. The site also provides an overview of how the concept of evolution has been researched and verified. This information can be used to dispel misconceptions that have been propagated by creationists. You can also access a glossary which includes terms used in evolutionary biology. These terms include: Adaptation is the tendency of heritable traits to be more suited to the environment. This is a result of natural selection. Organisms with more adaptable traits are more likely than those with less adaptable traits to reproduce and survive. Common ancestor (also called common ancestor) The most recent ancestor that is shared by two or more species. The common ancestor can be identified through analyzing the DNA of these species. Deoxyribonucleic acid: A huge biological molecule that contains the information needed for cell replication. The information is stored in nucleotide sequences, which are strung into long chains called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells. Coevolution is a relation between two species, where the evolution of one species are influenced evolutionary changes of the other. Examples of coevolution are the interactions between predator and prey, or the parasite and the host. Origins Species (groups of individuals who can interbreed) develop through an array of natural changes in the characteristics of their offspring. The causes of these changes are many factors, such as natural selection, gene drift and mixing of the gene pool. The development of a new species can take thousands of years, and the process may be slowed down or accelerated by environmental factors like climate change or competition for food or habitat. The Evolution site tracks the evolution of a variety of species of plants and animals over time and focuses on the most significant transitions that occurred in the evolution of each group's history. It also examines the evolution of humans, which is a topic of particular importance to students. When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap when it was published in 1858, a year following the initial edition of The Origin. While the site focuses on biology, it also offers a lot of information about geology and paleontology. One of the most appealing features of the website are a set of timelines that show how climatic and geological conditions have changed over time and an interactive map of the distribution of some fossil groups that are featured on the site. The site is a companion to a PBS TV series but it could also be used as an educational resource by teachers and students. The site is well-organized, and provides clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features of the museum's website. These hyperlinks make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are also links to John Endler's experiments with guppies, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment and has many advantages over modern observational and experimental methods of examining evolutionary processes. In addition to studying processes and events that take place regularly or over a long period of time, paleobiology is able to study the diversity of species of organisms and their distribution in space over the course of geological time. The site is divided into various paths that can be chosen to gain knowledge about evolution. One of the paths, “Evolution 101,” guides the user through the evolution of nature and the evidence of evolution. The path also reveals common misconceptions about evolution and 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. The site has a range of multimedia and interactive resources which include videos, animations, and virtual laboratories in addition to general textual content. The content is presented in a nested bread crumb fashion that aids navigation and orientation on the web site. The page “Coral Reef Connections”, for example, provides a comprehensive overview of the coral's relationships, their interaction with other organisms, and then is enlarged to show a single clam, which is able communicate with its neighbors and respond to changes in conditions of the water at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages offers a great introduction to the many areas of evolutionary biology. The content also includes an explanation of the role of natural selection and the concept of phylogenetic analysis, which is a key tool in understanding evolutionary change. Evolutionary Theory For biology students evolution is a crucial thread that weaves together all the branches of the field. A vast collection of books helps in teaching evolution across all disciplines of life science. One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and breadth in its educational resources. The site has a variety of interactive learning modules. It also has an “bread crumb structure” that allows students to move away from the cartoon style that is used in Understanding Evolution and onto elements of this vast website that are closely related to the worlds of research science. An animation that introduces students to the concept of genetics 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 materials that deal with evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives set out in the biology standards. It contains seven videos designed specifically for use in the classroom, and can be streamed for no cost or purchased on DVD. A variety of crucial questions remain in the midst of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is particularly true for human evolution, where it has been difficult to reconcile the notion that the physical characteristics of humans derived from apes with religious beliefs that hold that humans are unique in the universe and has an enviable place in creation, with soul. There are a variety of other ways in which evolution could occur including natural selection, which is the most well-known theory. However, scientists also study other kinds of evolution like mutation, genetic drift and sexual selection, among others. While many scientific fields of study conflict with literal interpretations found in religious texts, the concept of evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
