Evolution Site – Teaching About Evolution Despite the best efforts by biology educators, there are still a lot of misconceptions regarding evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution. This rich Web site – companion to the PBS series It provides teachers with materials that support evolution education and avoid the kinds of misinformation that can hinder it. It's organized in the “bread crumb” format to facilitate navigation and orientation. Definitions It is difficult to properly teach evolution. Non-scientists often misunderstand the subject, and some scientists even use a definition that confuses it. This is particularly relevant to debates about the nature of the word. It is crucial to define the terms used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful manner. It is an accompanying site for the 2001 series, but it is also a resource on its own. The material is presented in a nested fashion that assists in navigation and orientation. The site defines terms like common ancestor, the gradual process and adaptation. These terms help frame the nature of evolution as well as its relationship to other concepts in science. The website then provides an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel the myths created by creationists. It is also possible to find the glossary of terms used in evolutionary biology. These terms include: The process of adaptation is the tendency of heritable traits to become better suited to an environment. This is a result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adapted characteristics to survive and reproduce. Common ancestor: The latest common ancestor of two or more species. The common ancestor can be identified through analyzing 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 is a relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or host and parasite. Origins Species (groups that can crossbreed), evolve through a series of natural changes in the traits of their offspring. These changes are caused by a variety of factors such as natural selection, genetic drift and gene pool mixing. The evolution of new species could take thousands of years. Environmental conditions, such as climate change or competition for food or habitat, can slow or accelerate the process. The Evolution site traces through time the evolution of various animal and plant groups and focuses on major changes in each group's past. It also focuses on the evolutionary history of humans and humans, a subject that is particularly important for students to understand. When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. One of them was the infamous skullcap and associated bones found 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 after the first edition of the Origin appeared, it is very unlikely that Darwin had seen or heard of it. The site is mostly one of biology however, it also has lots of information about paleontology and geology. The website has several features that are especially impressive, including the timeline of the way that climate and geological conditions have changed over time. It also features maps that show the locations of fossil groups. The site is a companion to the PBS television series, but it can be used as a resource by teachers and students. The site is well-organized, and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features on the museum's website. These hyperlinks make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. In particular, there are links to John Endler's experiments using Guppies, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures within their geographical context and offers numerous advantages over the current observational and experimental methods for analyzing evolutionary processes. In addition to studying the processes and events that happen regularly or over a lengthy period of time, paleobiology can be used to study the diversity of species of organisms and their distribution across the course of geological time. The site is divided up into various paths that can be chosen to learn about evolution. One of the paths, “Evolution 101,” takes the viewer through the nature and evidence of evolution. 바카라 에볼루션 focuses on common misconceptions about evolution and the evolution of thought. Each of the other main sections of the Evolution site is equally created, with resources that can be used to support a range of curriculum levels and pedagogical styles. In addition to the standard textual content, the site also has a wide range of interactive and multimedia resources like video clips, animations, and virtual labs. The content is organized in a nested, bread crumb style that facilitates navigation and orientation within the vast Web site. For instance, the page “Coral Reef Connections” gives a brief overview of coral relationships and their interactions with other organisms. Then, it narrows down to a single clam that can communicate with its neighbors and respond to changes in the water conditions that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great introduction to a variety of topics in evolutionary biology. The content also includes an explanation of the importance of natural selection and the concept of phylogenetics analysis which is a crucial tool for understanding evolutionary changes. Evolutionary Theory For biology students the concept of evolution is a major thread that weaves together all the branches of the field. A wide selection of resources helps teachers teach 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 a Web page that offers both depth and breadth in terms of its educational resources. The site has a variety 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 massive website that are more closely linked to the field of research science. For example, an animation introducing the concept of genetic inheritance links to a page that focuses on John Endler's experiments with artificial selection with guppies in native ponds of Trinidad. The Evolution Library on this website has a huge multimedia library of materials that deal with evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives set out in the biology standards. It includes seven short videos specifically designed for use in classrooms. These can be viewed online or purchased as DVDs. A variety of crucial questions remain in the midst of evolutionary biology, such as the factors that trigger evolution and the speed at which it occurs. This is especially relevant to human evolution, which has made it difficult to reconcile the notion that the innate physical characteristics of humans evolved from apes with religious beliefs that claim that humanity is unique among living things and has a special place in creation with a soul. There are a myriad of other ways in which evolution can take place and natural selection being the most popular theory. However scientists also study other kinds of evolution like genetic drift, mutation, and sexual selection, among others. While many fields of scientific study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been a source of intense controversy and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the theories of evolution, other religions aren't.
