Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science nonsense has led many people to believe that biologists aren't believers in evolution. This rich Web site, which is a companion to the PBS program offers teachers resources that support the evolution of education, while avoiding the kinds of misconceptions that can undermine it. It's laid out in a “bread crumb” format to make navigation and orientation easier. Definitions It's difficult to properly teach evolution. Many non-scientists are unable to grasp the concept, and some scientists even use a definition that confuses it. This is particularly relevant when it comes to the definition of the words. 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 clear and helpful way. The site serves as an accompaniment to the 2001 series, but also a resource of its own. The material is presented in a nested manner that aids navigation and orientation. The site defines terms such as common ancestor, gradual process and adaptation. These terms help frame the nature and significance of evolution to other concepts in science. The website provides a summary of the ways the concept of evolution has been tested. This information can be used to dispel the myths that have been engendered by the creationists. You can also consult a glossary that contains terms used in evolutionary biology. These terms include: Adaptation is the tendency of heritable traits to be more suitable to their environment. This is the result of natural selection. Organisms with better-adapted traits are more likely than those with less adapted characteristics to survive and reproduce. Common ancestor: The most recent common ancestor of two or more different species. The common ancestor can be identified through analyzing the DNA of the species. Deoxyribonucleic acid: A massive biological molecule that contains the information necessary for cell replication. The information is stored in nucleotide sequences, which are strung into long chains, referred to as chromosomes. Mutations are the source of new genetic information in cells. Coevolution: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution include the interaction between predator and prey, or the parasite and the host. Origins Species (groups of individuals who can interbreed) evolve through natural changes in the characteristics of their offspring. These changes can be caused by various factors, including natural selection, gene drift, and mixing of the gene pool. The evolution of a new species may take thousands of years, and the process could be slowed or increased by environmental conditions such as climate change or the competition for food or habitat. The Evolution site tracks the development of a number of different animal and plant groups through time with a focus on the key shifts that occurred throughout each group's history. It also explores the evolutionary history of humans and humans, a subject that is crucial for students to comprehend. When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year before the first edition of the Origin was published, it's extremely unlikely that Darwin had seen or heard of it. While 에볼루션바카라사이트 focuses on biology, it also contains a wealth of information on geology and paleontology. The site offers a number of features that are particularly impressive, such as an overview of how climate and geological conditions have changed over the course of time. It also features an interactive map that shows the location of fossil groups. While the site is a companion piece to a PBS television show however, it can stand on its own as an excellent source for teachers and students. The site is well-organized, and provides clear links to the introduction content of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features of the museum website. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler’s experiments with guppies. They illustrate the importance of ecology in evolutionary theory. Diversity The evolution of life has produced many species of plants, animals and insects. Paleobiology, the study of these creatures within their natural environment is a superior method of study over modern observational or research methods of studying evolutionary processes. click the following article is able to study not only the process and events that happen regularly or over time but also the relative abundance and distribution of different groups of animals across geological time. The site is divided into several options to learn about evolution. One of these paths, “Evolution 101,” takes the viewer through the complexities and evidence of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thought. Each of the main sections of the Evolution website is equally well-developed, and includes materials that are suited to a variety of educational levels and teaching styles. The site includes a variety of interactive and multimedia content that include animations, video clips and virtual laboratories, in addition to its general textual content. The breadcrumb-like organization of the content helps with navigation and orientation on the massive Web site. The page “Coral Reef Connections” For instance, it gives a brief overview of the coral's relationships, their interaction with other organisms and is enlarged to show one clam that is able to communicate with its neighbours and respond to changes in conditions of the water 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 information also includes an explanation of the role of natural selection and the concept of phylogenetic analysis which is an important method to understand evolutionary change. Evolutionary Theory For biology students evolution is a crucial thread that weaves together all branches of the field. A rich collection supports teaching evolution across all disciplines of life science. One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both the depth and breadth of its educational resources. The site has a variety of interactive learning modules. It also features a nested “bread crumb” structure that allows students to move from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the world of research science. For example, an animation introducing the notion of genetic inheritance leads to a page that focuses on John Endler's artificial selection experiments with guppies from the native ponds of Trinidad. The Evolution Library on this website is a vast multimedia library of resources that are associated to evolution. The content is organized into curricula-based paths that correspond to the learning goals set forth in the standards for biology. It includes seven short videos designed specifically for classroom use, which can be streamed for no cost or purchased on DVD. A variety of crucial questions remain at the core of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is particularly true in the case of human evolution which was a challenge to reconcile religious beliefs that humanity has a unique place in creation and a soul with the idea that innate physical traits evolved from apes. Additionally there are a myriad of ways in which evolution could occur and natural selection is the most popular theory. Scientists also study different types such as mutation, genetic drift and sexual selection. While many fields of scientific inquiry have a conflict with the literal interpretations of religious texts Evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, others haven't.
