Evolution Site – Teaching About Evolution Despite the best efforts by biology educators, misconceptions persist about the evolution. Pop science nonsense has led people to believe that biologists don't believe evolution. This site, a companion to the PBS program offers teachers resources that support the evolution of education while avoiding the types of misconceptions which undermine it. It's laid out in a nested “bread crumb” format for ease of navigation and orientation. Definitions Evolution is a complicated and challenging subject to teach effectively. Many non-scientists are unable to grasp the concept, and some scientists even use a definition which confuses it. This is especially relevant to debates about the definition of the word itself. It is important to define terms that are used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful manner. The site is a companion to the show which first aired in 2001, but can also function as an independent resource. The content is presented in a nested fashion that aids navigation and orientation. The site defines terms like common ancestor, gradual process, and adaptation. These terms help to frame the nature of evolution and its relation to other concepts in science. The site also provides an overview of how the concept of evolution has been researched and validated. This information can help dispel the myths created by creationists. You can also access a glossary that contains terms that are used in evolutionary biology. These terms include: Adaptation: The tendency for heritable traits to become better suitable to a particular setting. This is a result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted traits to survive and reproduce. Common ancestor: The latest common ancestor of two or more different species. By studying the DNA of these species it is possible to determine the common ancestor. Deoxyribonucleic acid: A huge biological molecule that contains the information needed for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, referred to as chromosomes. Mutations are the basis for new genetic information in cells. Coevolution is a relationship between two species where evolution of one species are influenced by evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasites and hosts. Origins Species (groups which can interbreed), evolve through a series of natural changes in the traits of their offspring. The causes of these changes are many factors, such as 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 speeded up due to environmental conditions, such as climate change or competition for food or habitat. The Evolution site tracks the evolution of a variety of groups of animals and plants over time, focusing on the major transitions that occurred in the history of each group. It also explores human evolution, which is a topic of particular importance to students. When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, one year after the first edition of The Origin. Origin. While the site is focused on biology, it also offers a lot of information about geology as well as paleontology. The Web site has several features that are especially impressive, such as an overview of the way that climate and geological conditions have changed over the course of 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 be used as a resource for teachers and students. 에볼루션 바카라 체험 is very well-organized and offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These links make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are links to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology is the study of these creatures within their geographical context and offers numerous advantages over the modern observational and research methods for analyzing evolutionary phenomena. Paleobiology focuses on not only the process and events that happen frequently or over time, but also the distribution and frequency of various animal groups in space over the course of the geological time. The Web site is divided into a variety of paths to learning evolution which include “Evolution 101,” which takes the viewer on a liner path through the nature of science and the evidence that supports the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought. Each of the main sections of the Evolution website is equally well-designed, with materials that support a variety educational levels and teaching styles. The site offers a wide array of interactive and multimedia resources which include animations, video clips and virtual labs, in addition to its general textual content. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the large web site. For example the page “Coral Reef Connections” gives a brief overview of coral relationships and their interaction with other organisms, then concentrates on a specific clam that is able to communicate with its neighbours and respond to changes in water conditions that occur at the level of the reef. This page, along with the other multidisciplinary interactive and multimedia pages offers a great introduction to many topics in evolutionary biology. The material also provides an explanation of the role of natural selection and the concept of phylogenetic analysis, which is an important tool for understanding the evolution of change. Evolutionary Theory Evolution is an underlying thread that is found throughout all branches of biology. A vast collection of books helps in teaching evolution across all disciplines of life sciences. One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides the depth and breadth of its educational resources. The site has a wide array of interactive learning modules. It also has an embedded “bread crumb” structure that helps students move from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the world of research science. Animation that introduces the concept of genetics links to a page about John Endler's artificial-selection experiments with guppies on native ponds in Trinidad. Another helpful resource is the Evolution Library on this Web site, which has an extensive multimedia library of assets related to 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 biology standards. It contains seven videos designed specifically for classroom use, which can be streamed for no cost or purchased on DVD. Evolutionary biology is still a field of study that poses many important questions, such as what triggers evolution and the speed at which it occurs. This is especially applicable to human evolution where it's been difficult to reconcile that the physical traits of humans derived from apes, and the religious beliefs that claim that humanity is unique among living things and holds a an exclusive place in the creation, with soul. There are a myriad of other ways evolution can take place including natural selection, which is the most widely accepted theory. However, scientists also study other types of evolution such as genetic drift, mutation, and sexual selection, among others. While many scientific fields of inquiry conflict with the literal interpretations of the Bible evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
