Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution persist. People who have absorbed popular science myths often assume that biologists are saying they do not believe in evolution. This site, a companion to the PBS program that provides teachers with resources that support the evolution of education while avoiding the types of misconceptions that make it difficult to understand. It's organized in a nested “bread crumb” format to facilitate navigation and orientation. Definitions It's not easy to properly teach evolution. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is particularly relevant when it comes to the definition of the words. It is therefore important to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site serves as an accompanying site for the 2001 series, but it is also a resource on its own. The content is presented in a way that assists in navigation and orientation. The site defines terms such as common ancestor, gradual process and adaptation. These terms help to frame the nature of evolution and its relationship to other scientific concepts. The site also provides an overview of how the concept of evolution has been tested and confirmed. This information can be used to dispel the myths that have been propagated 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 heritable traits to become better suited to an environment. This is a result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adapted traits to survive and reproduce. Common ancestor (also known as common ancestor) The most recent ancestor that is shared by two or more species. The common ancestor can be identified by studying the DNA of those species. Deoxyribonucleic acid: A huge biological molecule that holds the information necessary for cell replication. 에볼루션 바카라 사이트 is stored in a sequence of nucleotides that are strung together into long chains, called chromosomes. Mutations are the basis for new genetic information within cells. Coevolution is a relation between two species, where the evolution of one species influence evolutionary changes in the other. Coevolution can be seen in the interaction of predator and prey, or parasite and hosts. Origins Species (groups that can crossbreed), evolve through a series natural changes in the traits of their offspring. The changes can be triggered by a variety of causes that include natural selection, genetic drift and mixing of genes. The evolution of new species could take thousands of years. Environmental conditions, like changes in the climate or competition for food resources and habitat, can slow or accelerate the process. The Evolution site traces through time the evolution of various groups of animals and plants and focuses on major changes within each group's past. It also examines the evolution of humans, which is a topic of particular importance for students. Darwin's Origin was published in 1859, when only a handful of antediluvian fossils of human beings had been discovered. The famous skullcap, with the bones associated with it were 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, just a year before the first edition of the Origin was published, it's extremely unlikely that Darwin had ever heard of it. While the site is focused on biology, it also offers a lot of information on geology and paleontology. The website has numerous features that are particularly impressive, including a timeline of the way that climate and geological conditions have changed over the course of time. It also features maps that show the locations of fossil groups. The site is a companion for a PBS television series, but it can 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 specialized elements of the museum's web site. These hyperlinks help users move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and has numerous advantages over the modern observational and research methods of examining evolutionary phenomena. Paleobiology focuses on not only the process and events that take place regularly or over time but also the relative abundance and distribution of different species of animals across geological time. The website is divided into different paths that can be chosen 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 the most common misconceptions about evolution, as well as the evolution theory's history. Each of the other sections of the Evolution site is similarly created, with resources that can support a variety of educational levels and pedagogical styles. In addition to general textual content, the site features an extensive selection of multimedia and interactive content including videos, animations and virtual laboratories. The breadcrumb-like arrangement of the content assists with navigation and orientation on the vast Web site. For example, the page “Coral Reef Connections” provides a comprehensive overview of coral relationships and their interactions 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 on the site, provide an excellent introduction to a wide range of topics in evolutionary biology. The material also provides an explanation of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool for understanding the evolution of changes. Evolutionary Theory Evolution is a common thread that runs through all branches of biology. A wide selection of resources helps teachers teach evolution across the life science disciplines. One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both depth and breadth in its educational resources. The site offers a variety of interactive learning modules. It also features a nested “bread crumb” structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this massive website that are closer to the world of research science. An animation that introduces students to the concept of genetics is linked to a page that highlights John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad. The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning objectives set out in the standards for biology. It contains seven videos specifically designed for use in the classroom, and can be streamed at no cost or purchased on DVD. A variety of crucial questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it happens. This is particularly relevant to human evolution, where it has been difficult to reconcile that the innate physical characteristics of humans derived from apes with religious beliefs that hold that humans are unique in the universe and has a special place in creation, with soul. There are also a number of other ways in which evolution can take place including natural selection, which is the most popular theory. However, scientists also study other kinds of evolution, such as genetic drift, mutation, and sexual selection, among others. Although many scientific fields of study conflict with the literal interpretations of religious texts, the concept of evolution biology has been a subject of intense debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, others haven't.
