Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution persist. People who have taken in the nonsense of pop science often believe that biologists are saying they don't believe in evolution. This rich website – companion to the PBS series offers teachers with resources which support evolution education and avoids the kinds of misconceptions that undermine it. It's organized in a “bread crumb” format to aid in navigation and orientation. Definitions Evolution is a complicated 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 especially relevant to discussions about the meaning of the word itself. It is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site serves as an accompaniment to the 2001 series, and it is also a resource on its own. The content is presented in a structured manner that makes it simpler to navigate and understand. The site defines terms like common ancestor (or common ancestor), gradual process and adaptation. These terms help define the nature and relationship of evolution to other scientific concepts. The site then offers an overview of how the concept of evolution has been vetted and validated. This information can be used to dispel misconceptions that have been engendered by the creationists. It is also possible to access the glossary of terms used in evolutionary biology. These terms include: The process of adaptation is the tendency of hereditary traits to become more suited to the environment. This is a result of natural selection, which occurs when organisms that have better adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics. Common ancestor: The latest common ancestor of two or more different species. 에볼루션 바카라사이트 can be identified through analyzing the DNA of the species. Deoxyribonucleic Acid: A large biological molecular containing the information required for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the cause of new genetic information in 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 parasite and host. Origins Species (groups which can interbreed), evolve through a series of natural changes in their offspring's traits. These changes are caused by a variety that include natural selection, genetic drift and mixing of gene pools. The development of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food and habitat can impede or accelerate the process. The Evolution site tracks the evolution of various groups of animals and plants over time with a focus on the key transitions that occurred in each group's history. It also focuses on the human evolutionary roots which is especially important for students to know. 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 the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year after the first edition of the Origin appeared, it is very unlikely that Darwin had heard or seen of it. While the site focuses on biology, it includes a good deal of information on geology and paleontology. Among the best features on the site are a set of timelines that show how geological and climatic conditions changed over time, and an outline of the distribution of a few of the fossil groups featured on the site. The site is a companion to a PBS TV series but it could be used as a resource for teachers and students. The site is well-organized and provides easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features on the museum's website. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are links to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life has led to a variety of plants, animals and insects. Paleobiology is the study of these creatures in their natural environment offers many advantages over the current observational or experimental methods for studying evolutionary processes. In addition to examining the processes and events that happen frequently or over a long period of time, paleobiology can be used to study the relative abundance of different species of organisms and their distribution throughout the course of geological time. The Web site is divided into various paths to learning evolution, including “Evolution 101,” which takes the user on a linear path through the scientific process and the evidence that supports the theory of evolution. The path also examines myths about evolution, as well as the history of evolutionary thinking. Each of the main sections on the Evolution website is equally well-developed, with materials that can be used to support a variety of levels of curriculum and teaching methods. The site offers a wide array of interactive and multimedia content, including animations, video clips and virtual labs as well as general textual content. The breadcrumb-like organization of the content assists with navigation and orientation on the large Web site. For instance, the page “Coral Reef Connections” provides an overview of coral relationships and their interaction with other organisms. Then, it narrows down to a single clam that can communicate with its neighbours and respond to changes in water conditions that occur at the reef level. 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 material also provides an explanation of the role of natural selection and the concept of phylogenetic analysis, which is an important tool in understanding evolutionary change. Evolutionary Theory For biology students, evolution is a key thread that binds all branches of the field. A vast collection of resources helps teachers teach about evolution across the life sciences. One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that provides the depth and the broadness in terms of educational resources. The site features a wealth of interactive learning modules. It also features an encased “bread crumb” structure that helps students move from the cartoon style of Understanding Evolution to elements on this large Web site closer to the world of research science. An animation that introduces the concept of genetics is linked to a page about John Endler's experiments in artificial selection using guppies on native ponds in Trinidad. The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized according to curricula-based pathways that correspond to the learning objectives set out in biology standards. It contains seven short videos designed for classroom use. These are available to stream or purchase as DVDs. 에볼루션코리아 of crucial questions remain in the midst of evolutionary biology, such as what triggers evolution and how fast it occurs. This is especially applicable to human evolution which has made it difficult to reconcile that the physical traits of humans were derived from apes, and the religions that believe that humans are unique among living things and has an enviable place in creation, with soul. Additionally, there are a number of ways that evolution could 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 other things. While many fields of scientific study are in conflict with literal interpretations found in religious texts, the concept of evolution biology has been the subject of intense debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
