Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution persist. Pop science fiction has led a lot of people to believe that biologists aren't believers in evolution. This site, which is a complement to the PBS program, provides teachers with materials which support evolution education, while avoiding the kinds of misconceptions that undermine it. Info 's organized in a nested “bread crumb” format for ease of navigation and orientation. Definitions Evolution is a complex and difficult subject matter to teach well. It is often misunderstood by non-scientists and even scientists use an interpretation that is confusing the issue. This is particularly relevant to discussions about the definition of the word itself. 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 useful manner. It is an accompaniment to the 2001 series, and also a resource of its own. The content is presented in a nested fashion that assists in navigation and orientation. The site defines terms like common ancestor, gradual process and so on. 에볼루션 카지노 help define the nature of evolution and its relationship to evolution with other scientific concepts. The site provides an overview of the way that evolution has been tested. This information will help to dispel the myths created by creationists. It is also possible to find a glossary of terms that are used in evolutionary biology. 에볼루션 카지노 include: The process of adaptation is the tendency of heritable traits to be more suited to the environment. This is the result of natural selection. Organisms with more adaptable traits are more likely than those with less-adapted traits to reproduce and survive. Common ancestor: The latest common ancestor of two or more distinct species. By analyzing DNA from these species it is possible to determine the common ancestor. Deoxyribonucleic acid: A large biological molecule that contains information required for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are the cause of new genetic information within cells. Coevolution is a relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or host and parasite. Origins Species (groups that can crossbreed), evolve through a series natural changes in the traits of their offspring. These changes can be caused by various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of a new species could take thousands of years and the process can be slowed down or accelerated due to environmental conditions, such as climate change or the competition for food or habitat. The Evolution site follows the emergence of various animal and plant groups, focusing on major transitions in each group's past. It also focuses on the evolutionary origin of humans, a topic that is crucial for students to know. Darwin's Origin was published in 1859, when just a handful of antediluvian fossils of humans were discovered. One of them was the infamous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap when it was published in 1858, which was a year after the first edition of The Origin. Origin. The site is mostly one of biology however, it also has lots of information about paleontology and geology. The website has numerous features that are especially impressive, including an overview of the way that climate and geological conditions have changed over time. It also features a map showing the distribution of fossil groups. The site is a companion to the PBS TV series but it could also be used as a source for teachers and students. The site is extremely well organized and provides clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. These hyperlinks help users move from the cartoon-like 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 illustrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures in their natural environment and has many advantages over the current observational and experimental methods of examining evolutionary phenomena. In addition to exploring processes and events that occur frequently or over a long period of time, paleobiology can be used to analyze the relative abundance of different groups of organisms and their distribution in space over the course of geological time. The site is divided into several optional paths to learning evolution, including “Evolution 101,” which takes the user on a linear path through the scientific process and the evidence that supports the theory of evolution. The path also explores misconceptions about evolution, as well as the history of evolutionary thinking. Each of the other main sections of the Evolution site is equally constructed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia content, including animations, video clips and virtual labs in addition to general textual content. The breadcrumb-like organization of the content helps with navigation and orientation on the massive website. The page “Coral Reef Connections”, for example, gives a brief overview of the relationships between corals and interactions with other organisms, and then is enlarged to show a single clam, which is able communicate with its neighbors and react to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a broad variety of topics in evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis which is a key tool in understanding evolutionary change. Evolutionary Theory Evolution is an underlying thread that runs through all branches of biology. A wide selection of resources helps teachers teach evolution across the life science disciplines. One resource, the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that provides depth as well as breadth in terms of its educational resources. The site offers a range of interactive learning modules. It also has an “bread crumb structure” that assists students in moving away from the cartoon style that is used in Understanding Evolution and onto elements on this large website more closely linked to the fields of research science. For instance an animation that introduces the concept of genetic inheritance links to a page that highlights John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad. The Evolution Library on this website has a huge multimedia library of materials that deal to evolution. The content is organized in curricula-based paths that correspond to the learning objectives outlined in biology standards. It contains seven videos designed specifically for use in the classroom, and can be streamed for free or purchased on DVD. Many important questions remain in the midst of evolutionary biology, including what triggers evolution and how fast it happens. This is particularly true for human evolution, where it has been difficult to reconcile the notion that the physical traits of humans derived from apes with religious beliefs that hold that humans are unique among living things and holds a an enviable place in creation, with soul. There are also a number of other ways evolution can take place, with natural selection as the most widely accepted theory. However, scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among other things. While many scientific fields of inquiry have a conflict with the literal interpretations of the Bible evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, others have not.
