Evolution Site – Teaching About Evolution Despite the best efforts by biology educators, there are still a lot of misconceptions about the evolution. People who have taken in the nonsense of pop science often believe that biologists claim they do not believe in evolution. This site, which is a companion to the PBS program, provides teachers with materials that promote evolution education, while avoiding the kinds of misconceptions that hinder it. It's organized in a nested “bread crumb” format to make it easy for navigation and orientation. Definitions Evolution is a complex and difficult subject to teach well. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition which confuses it. This is especially relevant when it comes to the definition of the words. Therefore, it is crucial to define the terms used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient way. The site is a companion to the series that first aired in 2001, but it also functions as an independent resource. The content is presented in an organized way that makes it easy to navigate and comprehend. The site defines terms such as common ancestor, the gradual process, and adaptation. These terms help to frame the nature of evolution as well as its relationship to other concepts in science. The website provides a summary of the manner the concept of evolution has been examined. This information can help dispel myths created by creationists. It is also possible to access a glossary of terms that are used in evolutionary biology. These terms include: Adaptation is the tendency of heritable traits to become more suitable to their environment. This is the result of natural selection. It occurs when organisms that have more adaptable traits are more likely survive and reproduce than those with less adapted traits. Common ancestor (also called common ancestor) The most recent ancestral ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of these species. Deoxyribonucleic acid: A large biological molecule that contains the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information within cells. Coevolution is a relationship between two species where evolutionary changes of one species influence evolutionary changes of the other. Coevolution can be seen in the interaction of predator and prey, or parasites and hosts. Origins Species (groups of individuals that can interbreed) evolve through an array of natural changes in the traits of their offspring. The changes can be triggered by a variety of causes that include natural selection, genetic drift and gene pool mixing. The evolution of new species could take thousands of years. Environmental conditions, such as climate changes or competition for food and habitat can slow or speed up the process. The Evolution site traces through time the emergence of various groups of animals and plants and focuses on major changes in each group's past. It also focuses on the human evolutionary roots and humans, a subject that is crucial for students to understand. Darwin's Origin was published in 1859, at a time when only a few antediluvian fossils of human beings had been discovered. The skullcap that is famous, along with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just a year before the first edition of the Origin was published, it's extremely unlikely that Darwin had seen or heard of it. The site is primarily a biology site however it also includes a lot of information on paleontology and geology. Among the best features of the Web site are a timeline of events which show how geological and climatic conditions have changed over time, as well as a map of the distribution of some of the fossil groups featured on the site. While the site is a companion piece to a PBS television show but it also stands on its own as a great resource for teachers and students. The site is well-organized and offers clear links to the introductory content of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features of the museum's website. These hyperlinks help users move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also 에볼루션 바카라 체험 to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory. Diversity The evolution of life has led to an array of animals, plants 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 just the processes and events that occur regularly or over time, but also the relative abundance and distribution of different species of animals across the geological time. The site is divided into different options to study the subject of evolution. One of the paths, “Evolution 101,” takes the viewer through the complexities and evidence of evolution. The path also explores misconceptions regarding evolution, as well as the history of evolutionary thought. Each of the main sections of the Evolution website is equally well-developed, and includes materials that can be used to support a variety of curriculum levels and teaching styles. In addition to the general textual content, the site features an array of multimedia and interactive content like video clips, animations, and virtual labs. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation within the large web site. For instance the page “Coral Reef Connections” gives a brief overview of coral relationships and their interactions with other organisms, then zooms in on a single clam that can communicate with its neighbors and respond to changes in water conditions that take place at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages gives a good introduction to the many areas of evolutionary biology. The content includes an overview of the role of natural selectivity and the concept of phylogenetics analysis which is a crucial tool for understanding evolutionary change. Evolutionary Theory Evolution is a common thread that connects all branches of biology. A vast collection of books helps in teaching evolution across all disciplines of life sciences. One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that provides depth and breadth in its educational resources. The site has a variety of interactive learning modules. It also features an “bread crumb structure” that helps students move away from the cartoon style of Understanding Evolution and onto elements of this vast website that are closely linked to the worlds of research science. For instance, an animation introducing the idea of genetic inheritance connects to a page that highlights John Endler's artificial selection experiments with guppies from the native ponds of Trinidad. Another resource that is worth mentioning is the Evolution Library on this web site, which has an extensive collection of multimedia assets related to evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning goals set forth in the standards for biology. It includes seven short videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD. Many important questions remain at the heart of evolutionary biology, including what causes evolution to occur and how fast it happens. This is especially true for human evolution, where it has been difficult to reconcile the idea that the physical characteristics of humans derived from apes and religious beliefs that claim that humans are unique among living things and has an enviable place in creation with soul. There are a variety of other ways evolution could occur and natural selection being the most popular theory. Scientists also study different types like mutation, genetic drift and sexual selection. While many scientific fields of study have a conflict with literal interpretations found in religious texts, the concept of evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
