Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, there are still a lot of misconceptions regarding evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution. This rich website – companion to the PBS series – provides teachers with materials which support evolution education and avoids the kinds of misinformation that can undermine it. It's organized in the “bread crumb” format to aid in navigation and orientation. Definitions It is difficult to properly teach evolution. It is often misunderstood by non-scientists and even some scientists are guilty of using an interpretation that is confusing the issue. This is particularly true when it comes to discussions on the nature of the word. Therefore, 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 manner. The site serves as a companion for the 2001 series, and also a resource on its own. The content is presented in a nested fashion that assists in navigation and orientation. The site defines terms such as common ancestor (or common ancestor), gradual process, and adaptation. These terms help frame the nature of evolution as well as its relationship to other scientific concepts. The site also provides an overview of how the concept of evolution has been vetted and verified. This information will help to dispel the myths created by creationists. It is also possible to get a glossary of terms that are used in evolutionary biology. These terms include: Adaptation is the tendency of hereditary traits to become better suited to an environment. This is the result of natural selection. It occurs when organisms that have better-adapted traits are more likely survive and reproduce than those with less adaptable characteristics. Common ancestor (also called common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of those species. Deoxyribonucleic acid: A huge biological molecule that contains information necessary for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information within cells. 무료에볼루션 : A relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or parasite and host. Origins Species (groups of individuals who can interbreed) change through natural changes in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food and habitat can impede or accelerate the process. The Evolution site tracks the evolution of a variety of animal and plant groups through time and focuses on the most significant shifts that occurred throughout each group's history. It also examines the evolution of humans, which is a topic of particular importance for students. Darwin's Origin was written in 1859, when just a few antediluvian fossils of human beings had been discovered. The famous skullcap, along with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, which was a year following the initial edition of The Origin. Origin. The site is primarily a biology site, but it also contains many details on paleontology and geology. One of the most appealing features of the website are a series of timelines that show the way in which climatic and geological conditions have changed over time and an interactive map of the distribution of some of the fossil groups featured on the site. The site is a companion for the PBS TV series but it can also be used as a resource by teachers and students. The site is very well-organized and offers clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These hyperlinks make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. In particular there are links to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life has led to an array of animals, plants and insects. Paleobiology is the study of these creatures within their natural environment, has many advantages over modern observational or experimental methods for exploring evolutionary processes. In addition to studying the processes and events that happen regularly or over a lengthy period of time, paleobiology is able to analyze the diversity of kinds of organisms as well as their distribution across the course of geological time. The website is divided into several routes that can be taken to gain knowledge about evolution. One of these paths, “Evolution 101,” takes the viewer through the evolution of nature and the evidence of evolution. The course also focuses on common misconceptions about evolution as well as the history of evolutionary thought. Each of the other major sections of the Evolution site is equally created, with resources that support a variety of curriculum levels and pedagogical styles. The site has a range of interactive and multimedia content which include animations, video clips and virtual laboratories, in addition to its 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 instance, it provides an overview of coral relationships and their interactions with other organisms and is enlarged to show a single clam, which is able to communicate with its neighbours and respond to changes in the water conditions that occur on 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 material includes an explanation of the role of natural selectivity and the concept of phylogenetics analysis, an important tool for understanding evolutionary changes. 에볼루션 무료 바카라 For biology students evolution is a crucial thread that connects all the branches of the field. A rich collection of resources helps teachers teach about evolution across the life sciences. One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides the depth and breadth of its educational resources. The site features a wide 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 linked to the realms of research science. Animation that introduces the concept of genetics, which links to a page that highlights John Endler's experiments with artificial selection using Guppies in native ponds in Trinidad. Another useful resource is the Evolution Library on this website, which includes an extensive library of multimedia resources related to evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in biology standards. It contains seven videos designed specifically for use in classrooms, and can be streamed for free or purchased on DVD. 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 occurs. 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 the creation and a soul with the notion that our physical traits were derived from the apes. There are a myriad of other ways evolution can take place including natural selection, which is the most well-known theory. Scientists also study other types such as genetic drift and sexual selection. While many fields of scientific inquiry conflict with literal interpretations of the Bible Evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolution, while others haven't.
