Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, there are still a lot of misconceptions regarding evolution. Pop science nonsense has led many people to believe that biologists don't believe evolution. This site, which is a companion to the PBS series It provides teachers with materials that promote evolution education and help avoid the kinds of myths that make it difficult to understand. It's organized in a nested “bread crumb” format to make it easy for navigation and orientation. Definitions It is difficult to effectively teach evolution. Many non-scientists are unable to grasp the concept and some scientists employ a definition that confuses it. This is particularly relevant to discussions about the definition of the word itself. It is therefore important to define the terms used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful way. The site is a companion to the show that premiered in 2001, but is also an independent resource. The content is presented in a nested fashion which aids navigation and orientation. The site defines terms like common ancestor and the gradual process. These terms help to frame the nature of evolution and its relationship to other scientific concepts. The website provides a summary of the way the concept of evolution has been examined. This information can help dispel myths that are created by the creationists. It is also possible to get a glossary of terms that are used in evolutionary biology. These terms include: Adaptation: The tendency for heritable characteristics to become more suitable to a particular setting. This is a result of natural selection, which happens when organisms that have better-adapted traits are more likely to survive and reproduce than those with less adaptable characteristics. Common ancestor: The latest common ancestor of two or more different species. The common ancestor can be identified by analyzing the DNA of the species. Deoxyribonucleic acid: A massive biological molecule that contains the information required for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are responsible for the creation of new genetic information inside cells. Coevolution is a relation between two species where evolutionary changes of one species are influenced by evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasite and hosts. Origins Species (groups that can crossbreed) develop through a series of natural changes in the traits of their offspring. These changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental circumstances, such as climate change or competition for food or habitat can slow or speed up the process. The Evolution site tracks the development of various species of plants and animals over time with a focus on the key shifts that occurred throughout each group's history. It also explores human evolution and is a subject that is particularly important to students. 에볼루션 룰렛 was written in 1859, at a time when only a few antediluvian fossils of humans had been found. Among them was the famous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, a year following the initial edition of The Origin. The site is mostly one of biology however it also includes many details on geology and paleontology. Among the best features on the site are a timeline of events that illustrate the way in which climatic and geological conditions have changed over time, and a map of the distribution of a few fossil groups that are featured on the site. The site is a companion for a PBS TV series but it can be used as a resource by teachers and students. The site is very well organized and provides clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler's experiments with guppies that illustrate the importance ecology in evolutionary theory. Diversity The evolution of life has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures within their geological context and has a number of advantages over modern observational and experimental methods in its exploration of evolutionary processes. In 에볼루션 바카라 체험 to studying processes and events that occur regularly or over a lengthy period of time, paleobiology can be used to analyze the diversity of kinds of organisms as well as their distribution throughout the geological time. The site is divided up into several routes that can be taken to study the subject of evolution. One of these paths, “Evolution 101,” guides the user through the complexities and evidence of evolution. The path also explores the most common misconceptions about 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 educational levels and teaching styles. The site has a range of interactive and multimedia content that include videos, animations, and virtual labs, in addition to its general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the massive website. The page “Coral Reef Connections” For instance, the page “Coral Reef Connections” provides an overview of the coral's relationships and interactions with other organisms and zooms in on a single clam, which can communicate with its neighbours 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 many topics in evolutionary biology. The content includes an overview of the significance of natural selectivity and the concept of phylogenetics, an important method for understanding the evolution of changes. Evolutionary Theory For biology students the concept of evolution is a major thread that binds all branches of the field. A rich collection of resources supports teaching about evolution across all life sciences. One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that offers both the depth and breadth of its educational resources. The site has a wide array of interactive learning modules. It also has a nested “bread crumb” structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this huge site that are more closely tied to the world of research science. An animation that introduces students to the concept of genetics is linked to a page highlighting John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad. The Evolution Library on this website has a huge multimedia library of materials that deal with evolution. The content is organized into curricula-based pathways that correspond to the learning objectives set out in biology standards. It includes seven short videos designed for classroom use. These can be streamed or purchased as DVDs. 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 relevant to human evolution, which has made it difficult to reconcile the idea that the physical characteristics of humans evolved from apes and religions that believe that humans are unique among living things and holds a an enviable place in creation, with a soul. In addition there are a myriad of ways in which evolution could occur, with natural selection being the most popular theory. However scientists also study different types of evolution such as genetic drift, mutation, and sexual selection, among others. Many fields of inquiry are in conflict with the literal interpretations of religious texts evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, other religions haven't.
