Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution persist. People who have taken in pop science nonsense often assume that biologists are saying they don't believe in evolution. This site, which is a complement to the PBS program, provides teachers with materials that support the evolution of education, while avoiding the kinds of misconceptions which hinder it. It's laid out in a “bread crumb” format to aid in navigation and orientation. Definitions It's not easy to teach evolution well. It is often misunderstood even by non-scientists, and even some scientists have been guilty of using an interpretation that is confusing the issue. This is particularly applicable to discussions about the definition of the word itself. As such, it is important to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site is both a companion for the 2001 series, but also a resource on its own. The material is presented in a nested manner that aids navigation and orientation. The site defines terms like common ancestor and gradual process. These terms help frame the nature of evolution and its relationship to evolution to other concepts in science. The site also provides an overview of how the concept of evolution has been researched and confirmed. This information will help to dispel the myths that are created by the creationists. It is also possible to find a glossary of terms used in evolutionary biology. These terms include: Adaptation is the process of changing heritable traits to become more suited to the environment. This is due to natural selection, which occurs when organisms that are more adaptable characteristics are more likely to survive and reproduce than those with less adapted traits. Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified by analyzing the DNA of those species. Deoxyribonucleic Acid: A massive biological molecular that contains 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 responsible for the creation of new genetic information within cells. Coevolution: A relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. 에볼루션 카지노 of coevolution are the interactions between predator and prey, or host and parasite. Origins Species (groups of individuals that can interbreed) evolve through a series of natural changes in the characteristics of their offspring. The changes can be triggered by a variety that include natural selection, genetic drift, and mixing of gene pools. The evolution of a new species may take thousands of years and the process could be slowed down or accelerated by environmental factors like climate change or competition for food or habitat. The Evolution site tracks the evolution of various animal and plant groups through time, focusing on the major transitions that occurred in the evolution of each group's history. It also examines the evolutionary origin of humans and humans, a subject that is especially important for students to know. When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. The skullcap that is famous, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just a year before the first edition of the Origin was published, it is highly unlikely that Darwin had seen or heard of it. The site is primarily a biology site, but it also contains a lot of information on paleontology and geology. The most impressive features on the site are a set of timelines that illustrate how climatic and geological conditions have changed over time and a map of the geographical distribution of some of the fossil groups featured on the site. The site is a companion to the PBS TV series but it could be used as a source for 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) as well as the more specialized features of the museum website. These links facilitate the transition from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are links to John Endler's research with guppies that illustrate the importance of ecology in evolutionary theory. Diversity The evolution of life has produced an array of plants, animals and insects. Paleobiology, the study of these creatures in their natural environment is a superior method of study over the current observational or experimental methods for studying evolutionary phenomena. In addition to studying the processes and events that happen regularly or over a long period of time, paleobiology allows to examine the relative abundance of various groups of organisms and their distribution in space over geological time. The Web site is divided into a variety of 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 path also examines myths about evolution, and the background of evolutionary thinking. Each of the other sections of the Evolution site is equally created, with resources that can be used to support a range of educational levels and pedagogical styles. In addition to general textual content, the site also has an extensive selection of multimedia and interactive resources including videos, animations and virtual labs. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation on the Web site. For instance the page “Coral Reef Connections” gives a brief overview of coral relationships and their interaction with other organisms, then zooms in on a single clam that is able to communicate with its neighbours and respond to changes in the water conditions at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to the broad variety of topics in evolutionary biology. The material also provides an overview of the importance of natural selection and the concept of phylogenetic analysis which is an important tool for understanding the evolution of change. Evolutionary Theory For biology students evolution is a crucial thread that weaves together all the branches of the field. A vast collection of resources can help teachers teach about evolution across all life sciences. One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both depth and breadth in its educational resources. The site offers a range of interactive learning modules. It also features an encased “bread crumb” structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely tied to the world of research science. 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 contains a large multimedia library of materials that deal to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives outlined in biology standards. It includes seven short videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD. A variety of crucial questions remain at the heart of evolutionary biology, such as the factors that trigger evolution and the speed at which it occurs. This is particularly true for human evolution, where it's been difficult to reconcile the notion that the physical characteristics of humans evolved from apes and religions that believe that humans are unique among living things and has an exclusive place in the creation with a soul. In 에볼루션코리아 there are a myriad of ways in which evolution could occur with natural selection being the most popular theory. Scientists also study other types such as mutation, genetic drift and sexual selection. While many scientific fields of study have a conflict with literal interpretations found in religious texts, evolution biology has been a subject 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.
