Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misinformation about evolution persist. Pop science nonsense has led many people to think that biologists don't believe in evolution. This rich website – companion to the PBS series – provides teachers with materials that promote evolution education and help avoid the kinds of myths that hinder it. It's organized in a nested “bread crumb” format to make it easy for navigation and orientation. Definitions Evolution is a complicated and difficult subject matter to teach effectively. It is often misunderstood by non-scientists and even scientists are guilty of using an interpretation that is confusing the issue. This is particularly relevant to discussions on the definition of the word itself. It is essential to define terms that are used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient manner. The site is a companion to the show that premiered in 2001, but it can also function as an independent resource. The content is presented in a structured way that makes it easy to navigate and comprehend. The site defines terms such as common ancestor and the gradual process. These terms help define the nature and relationship of evolution to other concepts in science. The site then offers an overview of how the concept of evolution has been tested and confirmed. This information can be used to dispel the myths that have been created by the creationists. You can also consult a glossary that contains 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 due to natural selection, which happens when organisms that have better-adapted traits are more likely survive and reproduce than those with less adaptable traits. Common ancestor (also called common ancestor) The most recent ancestral ancestor shared by two or more species. By analyzing DNA from these species, it is possible to identify the common ancestor. 무료 에볼루션 : A huge 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 basis for new genetic information within cells. Coevolution is a relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasites and hosts. Origins Species (groups that can interbreed) develop through a series natural changes in their offspring's traits. These changes can be caused by various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental circumstances, such as climate change or competition for food resources and habitat can impede or accelerate the process. The Evolution site follows the evolution of various species of plants and animals and focuses on major changes within each group's past. It also explores human evolution, which is a topic that is particularly important for students. Darwin's Origin was written in 1859, at a time when only a handful of antediluvian fossils of humans had been found. The most famous among them was the skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap when it was published in 1858, which was a year after the first edition of The Origin. Origin. While the site focuses on biology, it includes a good deal of information about geology and paleontology. Among the best features on the site are a series of timelines which show the way in which climatic and geological conditions have changed over time and an interactive map of the distribution of a few fossil groups listed on the site. The site is a companion to a PBS television series, but it can also be used as an educational resource for teachers and students. The site is well-organized and offers clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These hyperlinks make it easy to transition from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler’s experiments 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 is the study of these creatures in their geographical context and offers many advantages over modern observational and experimental methods of examining evolutionary processes. Paleobiology is able to study not only processes and events that happen regularly or over time but also the distribution and frequency of different groups of animals across the geological time. The website is divided into different routes that can be taken to study the subject of evolution. One of these paths, “Evolution 101,” walks the reader through the nature and evidence of evolution. The course also focuses on common misconceptions about evolution as well as the evolution of thought. Each of the other major sections of the Evolution site is equally developed, with materials that support a variety of curriculum levels and pedagogical styles. The site includes a variety of interactive and multimedia content, including animations, video clips 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. For example, the page “Coral Reef Connections” provides a comprehensive overview of the relationships between corals and their interaction with other organisms. It then narrows down to a single clam that is able to communicate with its neighbors and react to changes in the water conditions that take place at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to a wide range of topics in evolutionary biology. The material also provides an overview of the importance of natural selection and the concept of phylogenetic analysis, which is a crucial tool for understanding the evolution of changes. Evolutionary Theory Evolution is a common thread that runs through all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life sciences. One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth and breadth in terms of its educational resources. The site offers a variety of interactive learning modules. It also has an encased “bread crumb” structure that allows students to move 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 experiments in artificial selection using Guppies living in ponds native to Trinidad. Another helpful resource is the Evolution Library on this website, which includes an extensive collection of multimedia items that are related to evolution. The content is organized into curriculum-based paths that parallel the learning goals established in biology standards. It contains seven videos specifically intended for use in the classroom. They can be streamed or purchased as DVDs. A variety of crucial questions remain in the midst of evolutionary biology, such as the factors that trigger evolution and how fast it occurs. This is especially true for humans' evolution which was a challenge to reconcile religious beliefs that held that humanity has a special place in creation and a soul, with the idea that innate physical traits originated from the apes. In addition, there are a number of ways that evolution could occur and natural selection is the most widely accepted theory. Scientists also study different types such as mutation, genetic drift, and sexual selection. While many fields of scientific study have a conflict with the literal interpretations of religious texts, evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, other religions aren't.
