Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misinformation about evolution persist. People who have absorbed pop science nonsense often assume that biologists don't believe in evolution. This site, which is a companion to the PBS series It provides teachers with materials which support evolution education and avoids the kinds of misinformation that can undermine it. It's organized in a nested “bread crumb” format to make it easy for navigation and orientation. Definitions It's difficult to properly teach evolution. It is often misunderstood even by non-scientists, and even scientists have been guilty of using definitions that confuse the issue. This is particularly true when it comes to debates about the definition of the word itself. As such, it is essential to define terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful manner. The website is a companion to the show that premiered in 2001, but it is also an independent resource. The content is presented in an organized way that makes it easy to navigate and understand. The site defines terms like common ancestor, gradual process and adaptation. These terms help define the nature and significance of evolution to other concepts in science. The website provides a summary of the ways the concept of evolution has been tested. This information can help dispel myths created by creationists. You can also access a glossary which contains terms that are used in evolutionary biology. These terms include: Adaptation: The tendency for heritable characteristics to become more suitable to a particular setting. This is a result of natural selection, which happens when organisms with better adapted traits are more likely survive and reproduce than those with less adapted traits. 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 large biological molecule that contains the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains called chromosomes. 에볼루션 카지노 사이트 are the cause of new genetic information in cells. Coevolution is 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 the parasite and the host. Origins Species (groups which can interbreed), evolve through a series natural changes in their offspring's traits. The causes of these changes are many factors, such as natural selection, gene drift and mixing of the gene pool. The development of a new species could take thousands of years and the process could be slowed or increased due to environmental conditions, such as climate change or competition for food or habitat. The Evolution site tracks through time the emergence of various species of plants and animals, focusing on major transitions in each group's past. It also focuses on human evolution, which is a topic that is of particular interest to students. Darwin's Origin was written in 1859, when only a few antediluvian fossils of humans had been found. One of them was the infamous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was one year before the first edition of the Origin was published, it's extremely unlikely that Darwin had ever heard of it. The site is mostly an online biology resource however it also includes a lot of information on geology and paleontology. The most impressive features of the website are a series of timelines which show the way in which climatic and geological conditions have changed over time, as well as an interactive map of the distribution of some fossil groups listed on the site. Although the site is a companion piece to the PBS television show, it also stands on its own as an excellent resource for teachers and students. The site is very well-organized and offers clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. 에볼루션코리아 help users move 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, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life has produced a variety of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment, has many advantages over modern observational or research methods for exploring evolutionary phenomena. In addition to examining the processes and events that happen regularly or over a lengthy period of time, paleobiology is able to analyze the diversity of kinds of organisms as well as their distribution across geological time. The website is divided into a variety of paths to learning evolution, including “Evolution 101,” which takes the viewer on a liner path through the scientific process and the evidence supporting the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the history of evolutionary thought. Each of the main sections of the Evolution website is equally well-developed, with materials that support a variety levels of curriculum and teaching methods. In addition to the general textual content, the site features an extensive selection of multimedia and interactive resources including video clips, animations, and virtual labs. The breadcrumb-like structure of the content assists with navigation and orientation on 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 narrows down to a single clam that is able to communicate with its neighbors and react to changes in water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a wide range of topics in evolutionary biology. The information also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis, which is an important method to understand evolutionary changes. Evolutionary Theory Evolution is a common thread that connects all branches of biology. A vast 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 provides depth and broadness in terms of educational resources. The site has a wide array of interactive learning modules. It also has a “bread crumb structure” that assists students in moving away from the cartoon style used in Understanding Evolution and onto elements of this vast website that are closely related to the fields of research science. For example an animation that introduces the notion of genetic inheritance leads to a page that highlights John Endler's artificial selection experiments with guppies in native ponds of Trinidad. The Evolution Library on this website contains a large multimedia library of resources that are associated to evolution. The content is organized into courses that are based on curriculum and follow the learning goals established in the biology standards. It includes seven short videos specifically designed for use in classrooms, and can be streamed for no cost or purchased on DVD. A number of important questions remain at the heart of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is particularly relevant in the case of human evolution, where it was difficult to reconcile religious beliefs that held that humanity has a unique place in the creation and a soul, with the idea that innate physical traits originated from apes. In addition there are a myriad of ways that evolution can be triggered and natural selection is the most widely accepted theory. Scientists also study other kinds such as genetic drift, and sexual selection. While many fields of scientific inquiry are in conflict with the literal interpretations of religious texts, evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
