Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science nonsense has led people to believe that biologists don't believe evolution. This site, which is a companion to the PBS series – provides teachers with materials which support evolution education and avoid the kinds of myths that make it difficult to understand. It's laid out in the “bread crumb” format to make navigation and orientation easier. Definitions Evolution is a complicated and challenging subject to teach effectively. It is often misunderstood even by non-scientists, and even some scientists use a definition that confuses the issue. This is particularly true when discussing the nature of the words themselves. As such, it is crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful manner. It is a companion for the 2001 series, and it is also a resource on its own. The material is presented in a nested manner that aids navigation and orientation. The site defines terms such as common ancestor, gradual process and so on. These terms help to define the nature of evolution and its relationship to evolution with other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and validated. This information will help to dispel the myths that are created by the creationists. You can also access a glossary that contains terms that are used in evolutionary biology. These terms include: Adaptation: The tendency of hereditary traits to become more suitable to a particular setting. This is the result of natural selection. It occurs when organisms that are more adaptable traits are more likely survive and reproduce than those with less adapted traits. Common ancestor (also called common ancestor): The most recent ancestor shared by two or more species. By studying the DNA of these species, it is possible to identify the common ancestor. Deoxyribonucleic acid: A large biological molecule that contains information needed for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the source of new genetic information in cells. Coevolution is a relation between two species where evolution of one species are influenced by 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 that are able to interbreed) change through natural changes in the characteristics of their offspring. Changes can be caused by various factors, including natural selection, gene drift, and mixing of the gene pool. The evolution of a new species may take thousands of years, and the process can be slowed down or speeded up due to environmental conditions, such as climate change or competition for food or habitat. The Evolution site tracks the development of a variety of species of plants and animals over time and focuses on the most significant shifts that occurred throughout the evolution of each group's history. It also explores human evolution and is a subject that is particularly important to students. Darwin's Origin was written in 1859, when only a few antediluvian fossils of humans had been found. The famous skullcap, with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, one year after the first edition of the Origin was published, it's highly unlikely that Darwin had ever heard of it. The site is mostly a biology site, but it also contains lots of information about geology and paleontology. The Web site has several aspects that are quite impressive, including an overview of the way that climate and geological conditions have changed over time. It also includes a map showing the distribution of fossil groups. 에볼루션 is a companion to a PBS television series, but it can also be used as a resource by teachers and students. The site is well organized and provides clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These links make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. In particular there are links to John Endler's experiments using 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, the study of these creatures within their geological environment offers many advantages over the current observational or experimental methods for studying evolutionary phenomena. In addition to studying processes and events that take place regularly or over a long period of time, paleobiology is able to study the relative abundance of different groups of organisms and their distribution throughout the course of geological time. The website is divided into various options to gain knowledge about evolution. One of these paths, “Evolution 101,” guides the user through the evolution of nature and the evidence of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought. Each of the other major sections of the Evolution site is similarly developed, with materials that can support a variety of curriculum levels and pedagogical styles. The site includes a variety of interactive and multimedia content that include animations, video clips and virtual laboratories, in addition to its general textual content. The content is presented in a nested bread crumb style that facilitates navigation and orientation within the large web site. For instance, the page “Coral Reef Connections” provides a comprehensive overview of the relationships between corals and their interaction with other organisms. It then narrows down to 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 multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. 에볼루션 무료체험 includes an explanation of the role of natural selectivity and the concept phylogenetics analysis which is a crucial tool for understanding evolutionary change. Evolutionary Theory Evolution is a common thread that connects all branches of biology. A rich collection supports teaching evolution across the disciplines of life science. One resource, the companion to PBS's television show Understanding Evolution is an excellent example of a Web site that provides the depth and the breadth in terms of its educational resources. The site features a wide range of interactive learning modules. It also features a “bread crumb structure” that assists students in moving away from the cartoon-like style of Understanding Evolution and onto elements of this vast website that are closely linked to the fields of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page that focuses on John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad. Another useful resource is the Evolution Library on this site, which contains an extensive collection of multimedia items connected to evolution. The content is organized according to curricula-based pathways that correspond to the learning objectives set out in the standards for biology. 에볼루션 코리아 contains seven short videos specifically designed for classroom use. These are available to stream or purchase as DVDs. Evolutionary biology is still a field of study with a lot of important questions to answer, such as what triggers evolution and how fast it happens. This is especially true for the evolution of humans where it was a challenge to reconcile religious beliefs that held that humans have a distinct place in creation and a soul, with the notion that human beings have innate physical traits evolved from apes. There are also a number of other ways evolution can take place and natural selection being the most widely accepted theory. Scientists also study other kinds like mutation, genetic drift, and sexual selection. While many fields of scientific inquiry are in conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolution, but others haven't.
