Evolution Site – Teaching About Evolution Despite the best efforts by biology educators, misconceptions persist about evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution. This site, which is a companion to the PBS series – provides teachers with materials that promote evolution education and avoid the kinds of misinformation that can hinder it. It's organized in a nested “bread crumb” format for ease of navigation and orientation. Definitions Evolution is a complex and difficult subject matter to teach well. People who are not scientists often have a difficult time understanding the subject, and some scientists even use a definition that confuses it. This is particularly relevant when it comes to the meaning of the words themselves. It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful manner. It is an accompanying site for the 2001 series, and also a resource on its own. The information is presented in an organized manner that makes it easier to navigate and understand. The site defines terms such as common ancestor (or common ancestor), gradual process, and adaptation. These terms help define the nature and significance of evolution to other concepts in science. The website then provides an overview of how the concept of evolution has been vetted and verified. This information can be used to dispel myths that have been engendered by creationists. It is also possible to get the glossary of terms used in evolutionary biology. These terms include: Adaptation: The tendency for heritable traits to become better adaptable to a specific environment. This is the result of natural selection. Organisms with more adaptable characteristics 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. By studying the DNA of these species, it is possible to identify the common ancestor. Deoxyribonucleic Acid: A huge biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are the basis for new genetic information in cells. Coevolution: A relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey, or parasite and host. Origins Species (groups of individuals that can interbreed) evolve through natural changes in the characteristics of their offspring. The changes can be triggered by a variety of factors such as natural selection, genetic drift, and gene pool mixing. The evolution of a new species can take thousands of years and the process could be slowed down or accelerated due to environmental conditions, such as climate change or competition for food or habitat. The Evolution site traces through time the evolution of various animal and plant groups with a focus on major changes within each group's past. It also focuses on human evolution, which is a topic of particular importance for students. When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year after the first edition of the Origin was published, it is highly unlikely that Darwin had seen or heard of it. The site is primarily one of biology, but it also contains a lot of information on paleontology and geology. The Web site has a number of aspects that are quite impressive, including a timeline of how climate and geological conditions have changed over the course of time. It also features a map showing the distribution of fossil groups. While the site is a companion piece to the PBS television show however, it can stand on its own as an excellent source for teachers and students. The site is very well-organized and offers clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. Particularly, there are links to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life has resulted in an array of plants, animals and insects. Paleobiology is the study of these creatures in their geological context offers many advantages over modern observational or experimental methods of studying evolutionary phenomena. In addition to studying processes and events that take place frequently or over a long period of time, paleobiology is able to analyze the relative abundance of different kinds of organisms as well as their distribution throughout the course of geological time. The website is divided into various options to gain knowledge about evolution. One of the paths, “Evolution 101,” takes the viewer through the evolution of nature and the evidence of evolution. The path also explores the most common misconceptions about evolution, as well as the evolution of thought. Each of the other main sections of the Evolution site is equally developed, with materials that can be used to support a range of curriculum levels and pedagogical styles. In addition to general textual content, the site also has a wide range of multimedia and interactive resources including videos, animations and virtual laboratories. The breadcrumb-like structure of the content helps with navigation and orientation on the vast Web site. For instance the page “Coral Reef Connections” provides a comprehensive overview of coral relationships and their interaction with other organisms, then narrows down to a single clam that is able to communicate with its neighbors and react to changes in the water conditions at the level of the reef. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great 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 tool for understanding the evolution of change. Evolutionary Theory Evolution is an underlying thread that connects all branches of biology. A vast collection of books helps in teaching evolution across all disciplines of life science. 에볼루션 바카라 , which is a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that provides the depth and breadth of its educational resources. The site features a wide range of interactive learning modules. It also has an embedded “bread crumb” structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely tied to the field of research science. Animation that introduces the concept of genetics, which links to a page about John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad. The Evolution Library on this website contains a large multimedia library of assets related to evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives set out in the standards for biology. It contains seven videos specifically designed for classroom use, which can be streamed for free or purchased on DVD. Evolutionary biology remains an area of study that has many important questions, including what causes evolution and how quickly it happens. 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 religious beliefs that claim that humans are unique among living things and has an exclusive place in the creation with soul. There are a variety of other ways in which evolution can occur, 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 other things. Many fields of inquiry are in conflict with literal interpretations of religious texts Evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
