Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution remain. People who have been exposed to pop science nonsense often assume that biologists are saying they don't believe in evolution. This rich Web site, which is a companion to the PBS program that provides teachers with resources that promote evolution education, while avoiding the kinds of misconceptions that can hinder it. It's laid out in the “bread crumb” format to aid in navigation and orientation. Definitions Evolution is a complicated and difficult subject matter to teach effectively. It is often misunderstood even by non-scientists, and even some scientists are guilty of using definitions that confuse the issue. This is particularly relevant when discussing the definition of the words. It is therefore essential to define the terms used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful manner. It is a companion for the 2001 series, but also a resource of its own. The material is presented in a nested fashion that assists in navigation and orientation. The site defines terms such as common ancestor, gradual process and so on. These terms help frame the nature of evolution as well as its relation to other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and confirmed. This information can help dispel the myths that are created by the creationists. It is also possible to find a glossary of terms that are used in evolutionary biology. 에볼루션 슬롯 include: The process of adaptation is the tendency of hereditary traits to become better suited to an environment. This is due to natural selection, which happens when organisms with better adapted traits are more likely to survive and reproduce than those with less adaptable traits. Common ancestor: The most recent common ancestor of two or more different species. The common ancestor can be identified by studying the DNA of these species. Deoxyribonucleic Acid: A large biological molecular that holds the information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form long chains, also known as chromosomes. Mutations are responsible for the creation of new genetic information within cells. Coevolution: A relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution include the interaction between predator and prey, or host and parasite. Origins Species (groups of individuals who can interbreed) develop through natural changes in the characteristics of their offspring. Changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The development of new species can take thousands of years. Environmental circumstances, such as climate changes or competition for food resources and habitat, can slow or accelerate the process. The Evolution site traces through time the evolution of various animal and plant groups, focusing on major transitions within each group's past. It also explores human evolution and is a subject that is of particular interest for students. Darwin's Origin was published in 1859, when just a few antediluvian fossils of humans had been found. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, one year before the first edition of the Origin was published, it's extremely unlikely that Darwin had heard or seen of it. The site is mostly a biology site however it also includes lots of information about geology and paleontology. The Web site has several aspects that are quite impressive, such as an overview of how geological and climate conditions have changed over time. It also features an interactive map that shows the location of fossil groups. The site is a companion to the PBS television series, but it could also be used as a resource by teachers and students. The site is very well-organized and offers clear links between the introductory content 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 move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory. Diversity The evolution of life has resulted in many species of plants, animals and insects. Paleobiology is the study of these creatures in their geographical context and offers many advantages over modern observational and experimental methods for analyzing evolutionary phenomena. Paleobiology focuses on not just the processes and events that happen regularly or over time but also the relative abundance and distribution of different groups of animals in space throughout the geological time. The website is divided into different routes that can be taken to study the subject of evolution. One of the paths, “Evolution 101,” guides the user through the complexities and evidence of evolution. The path also explores common misconceptions about evolution as well as the evolution of thought. Each of the other major sections of the Evolution site is similarly developed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. The site has a range of multimedia and interactive resources that include videos, animations, and virtual laboratories in addition to general textual content. The breadcrumb-like structure of the content helps with navigation and orientation on the large website. For instance the page “Coral Reef Connections” provides a comprehensive overview of the relationships between corals and their interaction with other organisms. Then, 에볼루션 바카라 무료 concentrates on a specific clam that is able to communicate with its neighbors and respond to changes in the water conditions at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great introduction to many topics in evolutionary biology. The information also includes an explanation of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool for understanding the evolution of change. Evolutionary Theory Evolution is a common thread that connects all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life science. One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web site that provides depth as well as wide range of educational resources. The site offers a range of interactive learning modules. It also has an “bread crumb structure” that allows students to move away from the cartoon style used in Understanding Evolution and onto elements on this site that are more closely connected to the realms of research science. An animation that introduces the concept of genetics links to a page highlighting John Endler's artificial-selection experiments with guppies on native ponds in Trinidad. Another useful resource is the Evolution Library on this Web site, which contains an extensive multimedia library of resources connected to evolution. The content is organized into curriculum-based paths that parallel the learning objectives set out in the standards for biology. It contains seven videos designed for classroom use. They can be viewed online or purchased as DVDs. Evolutionary biology is an area of study that poses many important questions, including the causes of 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 the creation and a soul, with the notion that our physical traits were derived from the apes. In addition there are a myriad of ways that evolution can be triggered and natural selection is the most widely accepted theory. However scientists also study different kinds of evolution, such as mutation, genetic drift and sexual selection, among others. While many scientific fields of study are in conflict with literal interpretations found in religious texts, evolution biology has been a source of intense debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs to evolution but others haven't.
