Evolution Site – Teaching About Evolution Despite the best efforts of biology teachers, there are still misconceptions about the evolution. People who have been exposed to popular science myths often assume that biologists don't believe in evolution. This rich Web site, which is a complement to the PBS program offers teachers resources that promote evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's laid out in a nested “bread crumb” format to facilitate navigation and orientation. Definitions Evolution is a complex and challenging subject to teach effectively. It is often misunderstood even by non-scientists, and even some scientists use a definition that confuses the issue. This is particularly true when it comes to debates about the meaning of the word itself. Therefore, it is crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. The site is a companion site to the show that premiered in 2001, but it also functions as an independent resource. The material is presented in a nested manner that assists in navigation and orientation. The site defines terms such as common ancestor and the gradual process. These terms help frame the nature of evolution as well as its relation to other concepts in science. The website provides a summary of the manner that evolution has been examined. This information can help dispel myths that are created by the creationists. You can also access a glossary which includes terms that are used in evolutionary biology. These terms include: Adaptation: The tendency for hereditary traits to become more adaptable to a specific environment. This is the result of natural selection. Organisms with better-adapted traits are more likely than those with less adaptable characteristics to survive and reproduce. Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified by studying the DNA of the 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 to form long chains, also known as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells. Coevolution: A relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution is evident through the interaction between predator and prey, or parasite and hosts. Origins Species (groups of individuals that are able to interbreed) evolve through natural changes in the characteristics of their offspring. These changes are caused by a variety of factors that include natural selection, genetic drift and mixing of genes. look at here of a new species can take thousands of years and the process may be slowed down or accelerated due to environmental conditions, such as climate change or the competition for food or habitat. The Evolution site tracks the evolution of a variety of species of plants and animals over time, focusing on the major changes that took place in each group's history. It also examines the evolutionary origin of humans, a topic that is especially important for students to comprehend. Darwin's Origin was written in 1859, at a time when only a few antediluvian fossils of humans had been found. The famous skullcap, along with the associated bones, 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 published in 1858, one year after the first edition of The Origin. Origin. While the site is focused on biology, it contains a wealth of information on geology and paleontology. The most impressive features of the website are a series of timelines which show the way in which climatic and geological conditions have changed over time, as well as an interactive map of the distribution of a few fossil groups listed on the site. Although the site is a companion piece to a PBS television show, it also stands on its own as an excellent resource for teachers and students. The site is well-organized and offers clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features of the museum's website. These hyperlinks make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are links to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology, the study of these creatures in their geological environment, has many advantages over modern observational or research methods for studying evolutionary phenomena. In 에볼루션 바카라 체험 to exploring the processes and events that happen frequently or over a long period of time, paleobiology allows to analyze the diversity of species of organisms and their distribution in space over geological time. The site is divided into various pathways to understanding evolution which include “Evolution 101,” which takes the viewer on a line through the science of nature and the evidence that supports the theory of evolution. The path also explores misconceptions about evolution as well as the history of evolutionary thinking. Each of the main sections on the Evolution website is equally well-designed, with materials that support a variety educational levels and teaching styles. The site offers a wide array of multimedia and interactive resources which include videos, animations, and virtual laboratories, in addition to its general textual content. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the vast web site. The page “Coral Reef Connections” For instance, it gives a brief overview of coral relationships, their interaction with other organisms and is enlarged to show one clam that is able communicate with its neighbors and react to changes in conditions of the water 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 material also provides an overview of the importance of natural selection and the concept of phylogenetic analysis which is a key method to understand evolutionary change. Evolutionary Theory For biology students the concept of evolution is a major thread that connects all branches of the field. A rich collection supports teaching evolution across all disciplines of life sciences. One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides the depth and breadth of its educational resources. The site offers a range of interactive learning modules. It also features a nested “bread crumb” structure that helps students transition from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the field of research science. An animation that introduces students to the concept of genetics is linked to a page highlighting John Endler's experiments with artificial selection using guppies on native ponds in Trinidad. The Evolution Library on this website contains a large multimedia library of resources that are associated with evolution. The content is organized in 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 the classroom, and can be streamed for 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 occurs. This is especially relevant to human evolution, where it has been difficult to reconcile the notion that the physical traits of humans were derived from apes, and the religious beliefs that claim that humans are unique among living things and holds a an enviable place in creation, with a soul. There are a myriad of other ways in which evolution can occur and natural selection being the most popular theory. However, scientists also study other kinds of evolution, such as mutation, genetic drift, and sexual selection, among others. While many fields of scientific inquiry have a conflict with the literal interpretations of religious texts Evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, other religions have not.
