Evolution Site – Teaching About Evolution Despite the best efforts of biology teachers, misinformation about evolution persist. People who have absorbed popular science myths often assume that biologists don't believe in evolution. This rich Web site – companion to the PBS series It provides teachers with materials which support evolution education and help avoid the kinds of misconceptions that make it difficult to understand. It's organized in a “bread crumb” format to facilitate navigation and orientation. Definitions Evolution is a complicated and difficult subject matter to teach effectively. It is often misunderstood by non-scientists and even scientists use a definition that confuses the issue. This is particularly relevant when it comes to the definition of the words. Therefore, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site serves as a companion for the 2001 series, but it is also a resource on its own. The content is presented in a way 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 and its relation to other scientific concepts. The site provides an overview of the manner that evolution has been tested. This information can be used to dispel the myths that have been propagated by creationists. It is also possible to get a glossary of terms that are used in evolutionary biology. These terms include: Adaptation is the process of changing heritable traits to become better suited to an environment. This is a result of natural selection. It occurs when organisms that are better adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics. Common ancestor: The most recent 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 massive biological molecule that holds the information needed for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells. Coevolution is a relation between two species where evolutionary changes of one species are influenced evolutionary changes of the other. Examples of coevolution are the interactions between predator and prey, or host and parasite. Origins Species (groups which can interbreed) change through a series of natural changes in the traits of their offspring. These changes are caused by a variety of causes that include natural selection, genetic drift, and mixing of gene pools. The evolution of a new species can take thousands of years and the process can be slowed down or accelerated due to environmental conditions, such as climate change or competition for food or habitat. The Evolution site traces the emergence of a variety of species of plants and animals over time, focusing on the major shifts that occurred throughout each group's history. It also explores human evolution and is a subject that is particularly important for students. Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans were discovered. The famous skullcap, along with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was published in 1858, a year after the first edition of The Origin. Origin. While the site focuses on biology, it also contains a wealth of information about geology and paleontology. The site offers numerous features that are particularly impressive, including the timeline of the way that climate and geological conditions have changed over the course of time. It also has an interactive map that shows the location of fossil groups. While the site is a companion piece to a PBS television series but it also stands on its own as an excellent resource for teachers and students. 에볼루션 카지노 사이트 is extremely well-organized and offers clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These links facilitate the transition from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. In particular, there are links to John Endler's experiments using Guppies that demonstrate 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 a number of advantages over modern observational and experimental methods in its exploration of evolutionary processes. Paleobiology is able to study not only the process and events that occur regularly or over time, but also the relative abundance and distribution of different groups of animals in space over the course of the geological time. The website is divided into various paths to learning evolution, including “Evolution 101,” which takes the viewer on a liner path through the scientific process and the evidence supporting the theory of evolution. The course also focuses on 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. In addition to the standard textual content, the site features an extensive selection of multimedia and interactive resources like videos, animations, and virtual labs. The content is organized in a nested, bread crumb fashion that aids navigation and orientation within the large web site. For instance, the page “Coral Reef Connections” provides an overview of coral relationships and their interactions with other organisms, then narrows down to a single clam that can communicate with its neighbors and react to changes in water conditions that occur at the level of the reef. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a broad range of 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 key tool for understanding the evolution of change. Evolutionary Theory For biology students evolution is a crucial thread that connects all the branches of the field. A vast collection of resources can help teachers teach about evolution across the life sciences. One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of an Web page that offers both depth and breadth in terms of its 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-like style used in Understanding Evolution and onto elements on this large website more closely related to the worlds of research science. For instance an animation that explains the notion of genetic inheritance leads to a page highlighting John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad. Another helpful resource is the Evolution Library on this website, which includes an extensive multimedia library of assets that are related to evolution. The content is organized into curricula-based pathways that correspond to the learning goals established in the standards for biology. It contains seven short videos intended for use in the classroom. They are available to stream or purchase as DVDs. Evolutionary biology remains an area of study with a lot of important questions, including what causes evolution and how quickly it happens. This is particularly true for human evolution, which has made it difficult to reconcile that the physical characteristics of humans derived from apes and religions that believe that humans are unique among living things and holds a an enviable place in creation. It is soul. Additionally there are a myriad of ways that evolution could be triggered, with natural selection being the most widely accepted theory. Scientists also study other kinds like mutation, genetic drift and sexual selection. While many scientific fields of inquiry have a conflict with the literal interpretations of the Bible evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, other religions have not.
