Evolution Site – Teaching About Evolution Despite the best efforts by biology teachers, there are still misconceptions about the evolution. People who have absorbed pop science nonsense often assume that biologists are saying they do not believe in evolution. This site, which is a companion to the PBS series It 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 to make it easy for navigation and orientation. Definitions Evolution is a complex and difficult subject to teach well. It is often misunderstood by non-scientists, and even some scientists have been guilty of using a definition that confuses the issue. This is particularly relevant when discussing the definition of the words. It is therefore essential to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The site is both a companion for the 2001 series, and also a resource on its own. The content is presented in a structured manner that makes it simpler to navigate and understand. The site defines terms like common ancestor and the gradual process. These terms help define the nature and relationship of evolution to other scientific concepts. The site then offers an overview of how the concept of evolution has been vetted and verified. This information can be used to dispel misconceptions that have been engendered by creationists. You can also consult a glossary that contains terms used in evolutionary biology. These terms include: Adaptation is the tendency of hereditary traits to become more suitable to their environment. This is a result of natural selection, which happens when organisms with more adaptable traits are more likely to survive and reproduce than those with less adapted traits. Common ancestor: The most recent common ancestor of two or more species. The common ancestor can be identified by studying the DNA of these species. Deoxyribonucleic acid: A large biological molecule that contains information necessary for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are the source of new genetic information in cells. Coevolution: A relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or parasites and hosts. Origins Species (groups which can interbreed) change through a series natural changes in the traits of their offspring. The changes can be triggered by a variety of causes, including natural selection, genetic drift, and gene pool mixing. The evolution of new species can take thousands of years. Environmental conditions, such as climate change or competition for food resources and habitat can slow or speed up the process. The Evolution site follows the evolution of various animal and plant groups and focuses on major changes in each group's history. It also explores the human evolutionary roots and humans, a subject that is especially important for students to understand. When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. One of them was the infamous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known 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. 에볼루션 바카라 무료체험 is primarily an online biology resource however it also includes lots of information about paleontology and geology. Among 에볼루션 게이밍 on the site are a timeline of events that show the way in which climatic and geological conditions have changed over time and an outline of the distribution of some fossil groups listed on the site. The site is a companion to a PBS TV series but it could be used as a resource for teachers and students. The site is extremely well-organized and offers clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. 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 hyperlinks to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has led to a wide variety of animals, plants, and insects. Paleobiology is the study of these creatures in their geological context and has numerous advantages over modern observational and experimental methods in its exploration of evolutionary processes. In addition to studying processes and events that take place regularly or over a long period of time, paleobiology is able to analyze the relative abundance of various species of organisms and their distribution in space over the course of geological time. The site is divided up into different routes that can be taken to study the subject of evolution. One of these paths, “Evolution 101,” guides the user through the nature and evidence of evolution. The path also examines myths about evolution, and the background of evolutionary thinking. Each of the main sections on the Evolution website is equally well-developed, and includes materials that support a variety levels of curriculum and teaching methods. In addition to general textual content, the site features an array of multimedia and interactive content including video clips, animations, and virtual labs. The breadcrumb-like arrangement of the content assists with navigation and orientation on the large website. For example, the page “Coral Reef Connections” provides an overview of the relationships between corals and their interactions with other organisms, then concentrates on a specific clam that is able to communicate with its neighbors and respond to changes in the water conditions that take place at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to a variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is a crucial method to understand evolutionary changes. Evolutionary Theory Evolution is a common thread that is found throughout all branches of biology. A rich collection of resources supports teaching about evolution across the life sciences. One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that offers both the depth and the broadness in terms of educational resources. The site has a variety of interactive learning modules. It also features an embedded “bread crumb” structure that allows students to move from the cartoon-like 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 in artificial selection using Guppies in 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 into courses that are based on curriculum and follow the learning goals established in biology standards. It contains seven videos specifically designed for use in the classroom, and can be streamed at no cost or purchased on DVD. Many important questions remain in the midst of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is especially true for the evolution of humans, where it was difficult to reconcile religious beliefs that humanity has a unique place in the creation and a soul with the notion that human beings have innate physical traits evolved from apes. In addition there are a myriad of ways that evolution could occur, with natural selection being the most widely accepted theory. However scientists also study other kinds of evolution, such as mutation, genetic drift, and sexual selection, among other things. While many scientific fields of study have a conflict with the literal interpretations of religious texts, the concept of evolution biology has been a source of intense debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions aren't.
