Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misinformation about evolution remain. People who have absorbed popular science myths often assume that biologists don't believe in evolution. This rich website – companion to the PBS series – provides teachers with materials that promote evolution education and help avoid the kinds of misinformation that can hinder it. It's laid out in the “bread crumb” format to facilitate navigation and orientation. Definitions It is difficult to effectively teach evolution. It is often misunderstood even by non-scientists, and even some scientists have been guilty of using definitions that confuse the issue. This is especially relevant to discussions about the nature of the word. It is crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. The site serves as a companion for the 2001 series, and it is also a resource on its own. The content is presented in a nested fashion that aids navigation and orientation. The site defines terms such as common ancestor, the gradual process and adaptation. These terms help to define the nature of evolution and its relationship to other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and confirmed. This information can be used to dispel the myths that have been engendered by the creationists. It is also possible to access a glossary of terms used in evolutionary biology. These terms include: Adaptation is the process of changing heritable traits to become more suited to the environment. This is the result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adapted traits to survive and reproduce. Common ancestor: The latest common ancestor of two or more species. By analyzing the DNA from these species, it is possible to identify the common ancestor. Deoxyribonucleic Acid: A massive biological molecular containing the information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, called 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 dependent on evolutionary changes in the other. Coevolution is evident in the interaction of predator and prey, or parasites and hosts. Origins Species (groups that can interbreed) develop by a series of natural variations in their offspring's traits. The changes can be triggered by a variety of factors, including natural selection, genetic drift and mixing of gene pools. The evolution of new species can take thousands of years. Environmental conditions, such as climate change or competition for food resources and habitat, can slow or accelerate the process. The Evolution site traces the emergence of a variety of animal and plant groups through time, focusing on the major transitions that occurred in the history of each group. It also focuses on the human evolutionary roots which is especially important for students to know. When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The famous skullcap, along with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. 바카라 에볼루션 is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, which was a year after the first edition of The Origin. While the site is focused on biology, it contains a wealth of information about geology and paleontology. The site offers numerous features that are particularly impressive, including the timeline of how geological and climate conditions have changed over the course of time. 에볼루션바카라사이트 has maps that show the locations of fossil groups. The site is a companion for a PBS television series, but it could be used as a source for teachers and students. The site is well-organized and offers clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features of the museum website. These hyperlinks make it easy to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are hyperlinks to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life has produced an array of animals, plants and insects. Paleobiology, the study of these creatures within their geological context, has many advantages over the current observational or experimental methods of studying evolutionary phenomena. Paleobiology can examine not only the process and events that take place frequently or over time, but also the relative abundance and distribution of various animal groups in space over the course of the geological time. The website is divided into several routes that can be taken to gain knowledge about evolution. One of these paths, “Evolution 101,” guides the user through the complexities and evidence of evolution. The path also reveals common misconceptions about evolution and the evolution of thought. Each of the main sections on the Evolution website is equally well-designed, with materials that are suited to a variety of curriculum levels and teaching styles. In addition to the general textual content, the site offers a wide range of multimedia and interactive content including videos, animations and virtual laboratories. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the large Web site. The page “Coral Reef Connections” For instance, the page “Coral Reef Connections” provides a comprehensive overview of coral relationships and their interactions with other organisms and then zooms in on one clam, which is able to communicate with its neighbors and react to changes in conditions of the water at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, offers a great introduction to the many areas of evolutionary biology. The information also includes a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a key method to understand evolutionary changes. Evolutionary Theory Evolution is an underlying thread that is found throughout all branches of biology. A rich collection supports teaching evolution across all disciplines of life science. One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that provides depth as well as wide range of educational resources. The site offers a variety of interactive learning modules. It also has a nested “bread crumb” structure that allows students to move from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the field 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 living in ponds native to Trinidad. The Evolution Library on this website is a vast multimedia library of assets related to evolution. The content is organized into curriculum-based paths that parallel the learning objectives set out in biology standards. It contains seven videos designed specifically 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, including what triggers evolution and the speed at which it occurs. This is especially relevant to human evolution, where it has been difficult to reconcile the notion that the physical traits of humans derived from apes, and the religious beliefs that hold that humanity is unique in the universe and has an enviable place in creation, with a soul. There are a variety of other ways evolution could occur and natural selection being the most well-known theory. However, scientists also study other types of evolution such as genetic drift, mutation, and sexual selection, among other things. Many fields of inquiry conflict with literal interpretations of religious texts Evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions haven't.
