Evolution Site – Teaching About Evolution Despite the best efforts of biology teachers, there are still misconceptions about evolution. People who have been exposed to the nonsense of pop science often believe that biologists don't believe in evolution. This site, which is a companion to the PBS series offers teachers with resources that support evolution education and help avoid the kinds of misinformation that can make it difficult to understand. It's organized in a “bread crumb” format to facilitate navigation and orientation. Definitions Evolution is a complex and difficult subject to teach effectively. It is often misunderstood even by non-scientists, and even some scientists are guilty of using a definition that confuses the issue. This is particularly true when discussing the nature of the words themselves. Therefore, it is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient manner. The site is a companion site to the series that 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 and gradual process. These terms help define the nature and relationship of evolution with other scientific concepts. The site gives a comprehensive overview of the way the concept of evolution has been tested. 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. These terms include: The process of adaptation is the tendency of hereditary traits to become more suitable to their environment. This is the result of natural selection. Organisms with better-adapted characteristics are more likely than those with less-adapted characteristics to survive and reproduce. Common ancestor: The most recent common ancestor of two or more species. The common ancestor can be identified by studying the DNA of those species. Deoxyribonucleic acid: A huge biological molecule that contains information necessary for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are responsible for the creation of new genetic information within cells. Coevolution: A relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be seen through the interaction between predator and prey, or parasite and hosts. Origins Species (groups of individuals who can interbreed) change through an array of natural changes in the characteristics of their offspring. These changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The development of a new species could take thousands of years and the process could be slowed or increased by environmental conditions such as climate change or the competition for food or habitat. The Evolution site tracks through time the emergence of various species of plants and animals and focuses on major changes in each group's history. It also explores the evolutionary history of humans which is particularly important for students to comprehend. When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and bones that were discovered in 1856 at 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 appeared, it is highly unlikely that Darwin had seen or heard of it. While the site focuses on biology, it also includes a good deal of information about geology and paleontology. The Web site has several aspects that are quite impressive, including an overview of how climate and geological conditions have changed over the course of time. It also features a map showing the distribution of fossil groups. Although the site is a companion to a PBS television show however, it can stand on its own as a valuable source for teachers and students. The site is 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 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 using Guppies that demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology is the study of these creatures within their geological context and has numerous advantages over modern observational and experimental methods in its exploration of evolutionary processes. In addition to studying processes and events that occur regularly or over a long period of time, paleobiology allows to examine the relative abundance of different species of organisms and their distribution in space over the course of geological time. The site is divided up into various options to gain knowledge about evolution. One of the paths, “Evolution 101,” walks the reader through the evolution of nature and the evidence of evolution. The path also explores misconceptions about evolution as well as the history of evolutionary thinking. Each of the other sections of the Evolution site is similarly created, with resources that support a variety of different pedagogical levels and curriculum levels. In addition to general textual content, the site also has a wide range of multimedia and interactive content including videos, animations, and virtual labs. The breadcrumb-like structure of the content helps with navigation and orientation on the massive website. For instance the page “Coral Reef Connections” provides a comprehensive overview of the relationships between corals and their interaction with other organisms. Then, it concentrates on a specific clam that can communicate with its neighbors and react to changes in the water conditions that take place at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. 에볼루션 바카라 무료 includes a discussion on the importance of natural selection and the concept of phylogenetics analysis which is a crucial tool to understand evolutionary changes. Evolutionary Theory For biology students the concept of evolution is a major thread that connects all branches of the field. A rich collection supports teaching evolution across all disciplines of life science. One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that provides depth and breadth in its educational resources. The site has a wide array of interactive learning modules. It also has a nested “bread crumb” structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this massive website that are more closely tied to the field of research science. For example, an animation introducing the notion of genetic inheritance leads to a page that highlights John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad. Another helpful resource is the Evolution Library on this site, which contains an extensive collection of multimedia resources connected to evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives set out in the biology standards. It includes seven short videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD. A number of important questions remain at the core of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is especially true for human evolution, where it's been difficult to reconcile the idea that the innate physical characteristics of humans derived from apes with religious beliefs that claim that humanity is unique among living things and has an enviable place in creation with a soul. There are also a number of other ways in which evolution can take place, with natural selection as the most well-known theory. However scientists also study other kinds of evolution, such as mutation, genetic drift and sexual selection, among others. While many scientific fields of study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, other religions have not.
