Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, there are still a lot of misconceptions about the evolution. Pop science nonsense has led many people to think that biologists don't believe in evolution. This rich Web site, which is a complement to the PBS program that provides teachers with resources that promote evolution education, while avoiding the kinds of misconceptions which make it difficult to understand. It's laid out in a nested “bread crumb” format to make it easy for navigation and orientation. Definitions It's difficult to effectively teach evolution. It is often misunderstood even by non-scientists, and even some scientists have been guilty of using definitions that confuse the issue. This is especially relevant when discussing the meaning of the words themselves. As such, it is important to define terms that are used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful way. The site is both an accompanying site for the 2001 series, but also a resource of its own. The material is presented in a way which aids navigation and orientation. The site defines terms such as common ancestor, the gradual process and adaptation. These terms help define the nature of evolution and its relationship to evolution to other scientific concepts. The site provides an overview of the manner the concept of evolution has been examined. This information can be used to dispel the myths that have been created by creationists. It is also possible to find a glossary of terms that are used in evolutionary biology. These terms include: The process of adaptation is the tendency of heritable traits to become more suitable to their environment. This is a result of natural selection. Organisms with more adaptable traits are more likely than those with less adaptable traits to survive and reproduce. 에볼루션 바카라 무료체험 (also called common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of those species. Deoxyribonucleic Acid: A huge biological molecular that contains the information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, referred to as chromosomes. 에볼루션 코리아 are the reason behind the creation of new genetic information inside cells. Coevolution is the relationship between two species where evolution of one species are influenced evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey or host and parasite. Origins Species (groups of individuals that can interbreed) evolve through natural changes in the traits of their offspring. The causes of these changes are many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food and habitat can impede or accelerate the process. The Evolution site traces the emergence of various species of plants and animals over time and focuses on the most significant changes that took place in the history of each group. It also explores human evolution, which is a topic that is particularly important for students. Darwin's Origin was published in 1859, when only a handful of antediluvian fossils of humans had been found. One of them was the infamous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was one year before the first edition of the Origin was published, it is very unlikely that Darwin had ever heard of it. The site is mostly one of biology, but it also contains many details on geology and paleontology. Among the best features of the website are a series of timelines that illustrate how geological and climatic conditions changed over time, as well as an interactive map of the geographical distribution of some fossil groups that are featured on the site. Although the site is a companion piece to the PBS television show, it also stands on its own as a great resource for teachers and students. The site is well-organized and provides clear links to the introductory material 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 Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are hyperlinks to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has resulted in a variety of animals, plants, and insects. Paleobiology, the study of these creatures within their geological environment is a superior method of study over modern observational or research methods of studying evolutionary phenomena. In addition to examining processes and events that take place regularly or over a long period of time, paleobiology is able to examine the diversity of species of organisms and their distribution throughout the course of geological time. The website is divided into a variety of pathways to understanding evolution that include “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 explores misconceptions regarding evolution, and the background of evolutionary thinking. Each of the main sections of the Evolution website is equally well-developed, and includes materials that support a variety curriculum levels and teaching styles. In addition to the standard textual content, the site features an extensive selection of interactive and multimedia resources like videos, animations, and virtual laboratories. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the large web site. For example, the page “Coral Reef Connections” gives a brief overview of the relationships between corals and their interaction with other organisms. Then, it concentrates on a specific clam that is able to communicate with its neighbors and respond to changes in water conditions at the level of the reef. This page, along with the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to the many areas of evolutionary biology. The information also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis which is an important tool for understanding the evolution of change. Evolutionary Theory For biology students, evolution is a key thread that weaves together all the branches of the field. A wide range of resources supports teaching about evolution across all life sciences. One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that provides depth and breadth in terms of its educational resources. The site offers a variety of interactive learning modules. It also features an encased “bread crumb” structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the world of research science. An animation that introduces the concept of genetics, which links to a page that highlights John Endler's artificial-selection experiments with guppies on native ponds in Trinidad. The Evolution Library on this website has a huge multimedia library of resources that are associated to 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 contains seven videos designed specifically for classroom use, which can be streamed for free or purchased on DVD. Evolutionary biology is still a field of study with a lot of important questions, including what causes evolution and how quickly it happens. This is especially relevant to 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 humanity is unique in the universe and has an exclusive place in the creation, with a soul. There are a variety of other ways evolution can take place, with natural selection as the most widely accepted theory. However, scientists also study other kinds of evolution like mutation, genetic drift and sexual selection, among others. Many fields of inquiry conflict with literal interpretations of the Bible Evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, others have not.
