Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science fiction has led a lot of people to believe that biologists aren't believers in evolution. This rich Web site – companion to the PBS series offers teachers with resources which support evolution education and help avoid the kinds of myths that hinder it. It's organized in the “bread crumb” format to make navigation and orientation easier. Definitions It's not easy to properly teach evolution. It is often misunderstood even by non-scientists, and even scientists are guilty of using a definition that confuses the issue. This is especially relevant to discussions on the definition of the word itself. Therefore, it is essential to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site is both an accompaniment to the 2001 series, and also a resource of its own. The content is presented in a nested manner which aids 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 relationship to other scientific concepts. The site provides an overview of the way that evolution has been tested. This information can help dispel myths that are created by the creationists. It is also possible to access the glossary of terms used in evolutionary biology. These terms include: Adaptation: The tendency for heritable traits to become better suited to a particular environment. This is the result of natural selection, which happens when organisms that have better adapted traits are more likely to survive and reproduce than those with less adaptable characteristics. Common ancestor (also known as common ancestor): The most recent ancestor that is shared by two or more species. By analyzing DNA from these species, it is possible to determine the common ancestor. Deoxyribonucleic acid: A huge biological molecule that contains the information required for cell replication. The information is stored in nucleotide sequences, which are strung into long chains called chromosomes. Mutations are the basis for new genetic information in cells. Coevolution is a relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey or the parasite and the host. Origins Species (groups of individuals that are able to interbreed) develop through natural changes in the characteristics 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 a new species may take thousands of years, and the process can be slowed or increased due to environmental conditions, such as climate change or the competition for food or habitat. The Evolution site tracks the evolution of a number of different species of plants and animals over time, focusing on the major shifts that occurred throughout the history of each group. It also explores human evolution, which is a topic of particular importance for students. Darwin's Origin was written in 1859, when only a handful of antediluvian fossils of human beings had been discovered. The famous skullcap, with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, a year after the first edition of The Origin. While 에볼루션 바카라 무료체험 focuses on biology, it contains a wealth of information about geology and paleontology. The most impressive features of the Web site are a timeline of events that show the way in which climatic and geological conditions have changed over time, as well as an outline of the distribution of a few of the fossil groups featured on the site. The site is a companion for the PBS TV series but it can be used as a resource by teachers and students. The site is extremely well-organized and has clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies. They demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment and has many advantages over the modern observational and research methods in its exploration of evolutionary processes. In addition to examining processes and events that take place regularly or over a long period of time, paleobiology is able to study the relative abundance of various groups of organisms and their distribution across the course of geological time. The site is divided into several options to study the subject of evolution. One of these paths, “Evolution 101,” takes the viewer through the complexities and evidence of evolution. The path also examines myths about evolution, and also the history of evolutionary thought. Each of the other main sections of the Evolution site is similarly created, with resources that can support a variety of different pedagogical levels and curriculum levels. The site offers a wide array of multimedia and interactive resources that include video clips, animations and virtual laboratories, in addition to its general textual content. The content is presented in a nested bread crumb fashion that aids navigation and orientation on the web site. The page “Coral Reef Connections”, for example, gives a brief overview of coral relationships, their interaction with other organisms, and then is enlarged to show one clam that is able communicate with its neighbors and react to changes in the conditions of the water at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, offers a great introduction to a variety of topics in evolutionary biology. The content also includes an explanation of the role of natural selection and the concept of phylogenetic analysis which is an important tool for understanding the evolution of change. Evolutionary Theory Evolution is an underlying thread that connects all branches of biology. A vast collection of books helps in teaching evolution across the disciplines of life science. One resource, the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that provides the depth and the broadness in terms of educational resources. The site offers a variety of interactive learning modules. It also has a nested “bread crumb” structure that helps students move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the world of research science. For example an animation that introduces the idea of genetic inheritance connects to a page that highlights John Endler's artificial selection experiments with guppies in native ponds of Trinidad. The Evolution Library on this website is a vast multimedia library of materials that deal with evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives set out in the biology standards. It includes seven short videos designed for classroom use. These are available to stream or purchase as DVDs. A variety of crucial questions remain in the midst of evolutionary biology, such as what triggers evolution and how fast it happens. This is especially true in the case of human evolution where it was a challenge to reconcile religious beliefs that humanity has a unique position in the universe and a soul, with the idea that innate physical traits evolved from apes. In addition, there are a number of ways in which evolution could occur and natural selection is the most popular theory. However scientists also study different kinds of evolution like mutation, genetic drift and sexual selection, among others. Although many scientific fields of study have a conflict with literal interpretations found in religious texts, the concept of evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, other religions haven't.
