Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, there are still a lot of misconceptions about the evolution. People who have taken in pop science nonsense often assume that biologists do not believe in evolution. This rich Web site, which is a complement to the PBS program, provides teachers with materials that promote evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's arranged in a nested “bread crumb” format to make it easy for navigation and orientation. Definitions Evolution is a complicated and challenging subject to teach effectively. It is often misunderstood even by non-scientists, and even scientists use definitions that confuse the issue. This is especially true when discussing the meaning of the words themselves. As such, it is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site is both an accompaniment to the 2001 series, but also a resource of its own. The material is organized in a way that makes it easy to navigate and comprehend. The site defines terms like common ancestor, gradual process and so on. These terms help define the nature of evolution and its relationship to evolution with other scientific concepts. The website provides a summary of the ways in which evolution has been examined. This information can help dispel the myths created by creationists. It is also possible to access the glossary of terms used in evolutionary biology. These terms include: Adaptation is the tendency of heritable traits to be more suitable to their environment. This is due to natural selection, which happens when organisms that have more adaptable traits are more likely survive and reproduce than those with less adaptable characteristics. Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified through analyzing the DNA of these species. Deoxyribonucleic Acid: A huge biological molecular that contains the information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, called chromosomes. Mutations are responsible for the creation of new genetic information within cells. Coevolution: A relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasite and hosts. Origins Species (groups that can crossbreed) change through a series of natural changes in the traits of their offspring. The changes can be caused by a variety, including natural selection, genetic drift and mixing of gene pools. The development of new species can take thousands of years. Environmental conditions, like climate change or competition for food and habitat, can slow or accelerate the process. 에볼루션 바카라 사이트 through time the evolution of different animal and plant groups, focusing on major transitions in each group's past. It also examines the evolution of humans as a subject of particular importance for students. Darwin's Origin was published in 1859, when just 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 that is now thought as an early Homo neanderthalensis. 에볼루션 is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, which was a year after the first edition of The Origin. While the site is focused on biology, it also includes a good deal of information about geology and paleontology. One of the most appealing features of the Web site are a set of timelines which show how climatic and geological conditions have changed over time, as well as an interactive map of the geographical distribution of some of the fossil groups featured on the site. The site is a companion for the PBS TV series but it can also be used as an educational resource for teachers and students. The site is well-organized and has 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 hyperlinks make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are hyperlinks to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life has produced many species of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment and has a number of advantages over the modern observational and research methods in its exploration of evolutionary processes. Paleobiology is able to study not just the processes and events that take place regularly or over time but also the distribution and frequency of different species of animals in space over the course of geological time. The site is divided up into several paths that can be chosen to study the subject of evolution. One of the paths, “Evolution 101,” guides the user through the evolution of nature and the evidence of evolution. The path also examines myths about evolution and also the history of evolutionary thinking. Each of the main sections of the Evolution website is equally well-developed, with materials that support a variety educational levels and teaching styles. The site includes a variety of multimedia and interactive resources, including animations, video clips and virtual laboratories as well as general textual content. The breadcrumb-like organization of the content assists with navigation and orientation on the massive web site. The page “Coral Reef Connections”, for example, provides an overview of the relationships between corals, their interaction with other organisms and then is enlarged to show one clam that is able to 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 many topics in evolutionary biology. The material includes an explanation of the importance of natural selection and the concept of phylogenetics analysis as a key method for understanding the evolution of changes. Evolutionary Theory For biology students the concept of evolution is a major thread that weaves together all branches of the field. A rich collection of resources can help teachers teach about evolution across all life sciences. One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that provides depth and a variety of educational resources. The site offers a range of interactive learning modules. It also has a “bread crumb structure” that helps students move away from the cartoon-like style used in Understanding Evolution and onto elements of this vast website that are closely linked to the fields of research science. For instance an animation that explains the notion of genetic inheritance leads to a page that highlights John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad. The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives outlined in the standards for biology. It includes seven short videos specifically intended for use in the classroom. These can be viewed online or purchased as DVDs. A number of important questions remain at the heart of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is especially true for humans' evolution where it was a challenge to reconcile religious beliefs that held that humans have a distinct place in the creation and a soul, with the notion that our physical traits evolved from apes. Additionally there are a variety of ways that evolution could be triggered, with natural selection being the most widely accepted theory. However, scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among others. While many scientific fields of study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been a source of intense debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution but others haven't.
