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 aren't believers in evolution. This rich Web site, which is a complement to the PBS program, provides teachers with materials which support evolution 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 Evolution is a complicated and challenging subject to teach effectively. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is especially relevant when discussing the meaning of the words themselves. 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 way. The site is both an accompanying site for the 2001 series, and also a resource of its own. The material is presented in a nested fashion which aids navigation and orientation. The site defines terms like common ancestor, gradual process and adaptation. These terms help frame the nature and significance of evolution with other scientific concepts. The website then provides an overview of how the concept of evolution has been researched and verified. This information can help dispel the myths created by creationists. You can also access a glossary that includes terms used in evolutionary biology. These terms include: Adaptation is the tendency of heritable traits to become more suited to the environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted characteristics to survive and reproduce. Common ancestor (also called common ancestor) is the most recent ancestor shared by two or more species. The common ancestor can be identified by analyzing the DNA of those species. Deoxyribonucleic acid: A huge biological molecule that contains information required for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information inside cells. Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution is evident in the interaction of predator and prey, or parasite and hosts. Origins Species (groups of individuals that are able to interbreed) change through natural changes in the traits of their offspring. The changes can be caused by a variety of factors such as natural selection, genetic drift and mixing of gene pools. The evolution of new species could take thousands of years. Environmental circumstances, such as climate changes or competition for food and habitat can impede or accelerate the process. The Evolution site tracks the evolution of a number of different groups of animals and plants over time and focuses on the most significant transitions that occurred in the history of each group. It also focuses on human evolution, which is a topic that is particularly important to students. Darwin's Origin was published in 1859, at a time when only a handful of antediluvian fossils of humans were discovered. One of them was the infamous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany which is now believed as 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. Origin. The site is mostly a biology site, but it also contains a lot of information on geology and paleontology. The Web site has numerous features that are particularly impressive, such as an overview of how climate and geological conditions have changed over time. It also includes an interactive map that shows the location of fossil groups. While the site is a companion piece to the PBS television series however, it can stand on its own as a great resource for teachers and students. The site is extremely well-organized and has clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These hyperlinks make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. In particular there are hyperlinks 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 animals, plants, and insects. 에볼루션 바카라 체험 is the study of these creatures in their geological context and has a number of advantages over the current observational and experimental methods in its exploration of evolutionary phenomena. Paleobiology can examine not just the processes and events that take place regularly or over time, but also the relative abundance and distribution of various animal groups in space throughout geological time. The website is divided into different options to learn about evolution. One of the paths, “Evolution 101,” takes the viewer through the nature and evidence of evolution. The course also focuses on misconceptions regarding evolution, and the background of evolutionary thinking. Each of the other sections of the Evolution site is equally well constructed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. In addition to general textual content, the site offers an array of multimedia and interactive resources including videos, animations, and virtual labs. The breadcrumb-like arrangement of the content helps with navigation and orientation on the vast Web site. For example, the page “Coral Reef Connections” provides an overview of coral relationships and their interactions with other organisms, then zooms in on a single clam that is able to communicate with its neighbours and respond to changes in the water conditions that occur at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to the broad spectrum of topics in evolutionary biology. The content also includes an overview of the role of natural selectivity and the concept phylogenetics analysis as a key tool to understand evolutionary changes. 에볼루션 바카라 무료 For biology students, evolution is a key thread that weaves together all branches of the field. A rich collection supports teaching evolution across the life science disciplines. One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that offers both the depth and the broadness in terms of educational resources. The site has a wide array of interactive learning modules. It also features a nested “bread crumb” structure that allows students to move from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the world of research science. An animation that introduces the concept of genetics, which links to a page highlighting John Endler's experiments with artificial selection using guppies on native ponds in Trinidad. Another useful resource is the Evolution Library on this site, which has an extensive collection of multimedia resources that are related to evolution. The content is organized into curriculum-based paths that parallel the learning goals established in biology standards. It includes seven short videos specifically designed for use in the classroom, and can be streamed for no cost or purchased on DVD. Many important questions remain at the core of evolutionary biology, such as the factors that trigger evolution and how fast it occurs. This is especially true for humans' evolution which was a challenge to reconcile religious beliefs that humanity has a special place in creation and a soul with the notion that human beings have innate physical traits were derived from Apes. Additionally there are a variety of ways that evolution could be triggered with natural selection being the most widely accepted theory. Scientists also study other types such as genetic drift and sexual selection. While many fields of scientific study are in conflict with the literal interpretations of religious texts, the concept of evolution biology has been a subject of intense debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, while others haven't.
