Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions persist regarding evolution. Pop science nonsense has led people to believe that biologists don't believe evolution. This rich Web site, a companion to the PBS program offers teachers resources that promote evolution education, while avoiding the kinds of misconceptions that hinder it. It's laid out in the “bread crumb” format to aid in navigation and orientation. Definitions Evolution is a complex and difficult subject to teach effectively. It is often misunderstood by non-scientists, and even some scientists have been guilty of using a definition that confuses the issue. This is especially relevant when it comes to the nature of the words themselves. 에볼루션 무료 바카라 is crucial to define the 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 a companion to the show that premiered in 2001, but it can also function as an independent resource. The information is presented in an organized manner that makes it simpler to navigate and understand. The site defines terms such as common ancestor and the gradual process. These terms help frame the nature of evolution and its relationship to other concepts in science. The site then offers an overview of how the concept of evolution has been tested and validated. This information can be used to dispel the myths that have been created by the creationists. It is also possible to get a glossary of terms that are used in evolutionary biology. These terms include: Adaptation: The tendency of hereditary traits to become more suited to a particular environment. This is a result of natural selection, which happens when organisms that have more adaptable traits are more likely to survive and reproduce than those with less adaptable traits. Common ancestor (also called common ancestor) The most recent ancestor that is shared by two or more species. By studying the DNA of these species, it is possible to identify the common ancestor. Deoxyribonucleic Acid: A large biological molecular that contains the information needed for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells. Coevolution is the relationship between two species where evolution of one species influence evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey, or host and parasite. Origins Species (groups of individuals that can interbreed) develop through natural changes in the characteristics of their offspring. The changes can be caused 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 speeded up due to environmental conditions, such as climate change or competition for food or habitat. The Evolution site tracks the evolution of a variety of groups of animals and plants over time and focuses on the most significant changes that took place in each group's history. It also examines the evolutionary origin of humans and humans, a subject that is crucial for students to understand. Darwin's Origin was published in 1859, when just a handful of antediluvian fossils of human beings had been discovered. The famous skullcap, along with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year after the first edition of the Origin was published, it's highly unlikely that Darwin had seen or heard of it. While the site focuses on biology, it offers a lot of information about geology as well as paleontology. Among the best features of the website are a timeline of events that show the way in which climatic and geological conditions changed over time, as well as a map of the distribution of a few fossil groups that are featured on the site. The site is a companion for a PBS TV series but it could also be used as an educational resource for teachers and students. The site is extremely well-organized and offers clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler’s experiments with guppies that illustrate the importance ecology in evolutionary theory. Diversity The evolution of life on Earth has produced a diversity of animals, plants and insects. Paleobiology, the study of these creatures in their geological environment offers many advantages over modern observational or research methods of studying evolutionary processes. In addition to examining processes and events that occur regularly or over a lengthy period of time, paleobiology can be used to study the relative abundance of different kinds of organisms as well as their distribution across the geological time. The website is divided into different paths that can be chosen to gain knowledge about evolution. One of these paths, “Evolution 101,” walks the reader through the evolution of nature and the evidence of evolution. The path also examines myths about evolution as well as the history of evolutionary thinking. Each of the main sections on the Evolution website is equally well-developed, with materials that are suited to a variety of educational levels and teaching styles. The site offers a wide array of multimedia and interactive resources, including videos, animations, and virtual laboratories, in addition to its general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the vast website. For instance the page “Coral Reef Connections” provides a comprehensive overview of the relationships between corals and their interaction with other organisms. Then, it concentrates on a specific clam that can communicate with its neighbours and respond to changes in water conditions that occur at the level of the reef. This page, along with the other multidisciplinary multimedia and interactive pages, provides an excellent introduction to many topics in evolutionary biology. The material also provides an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is an important tool in understanding evolutionary changes. Evolutionary Theory For biology students the concept of evolution is a major thread that connects all the branches of the field. A wide range of resources helps teachers teach about evolution across the life sciences. One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that provides depth and broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also features a “bread crumb structure” that assists students in moving away from the cartoon-like style of Understanding Evolution and onto elements of this vast website that are closely related to the realms of research science. For example, an animation introducing the idea of genetic inheritance connects to a page that highlights John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad. Another useful resource is the Evolution Library on this site, which contains an extensive multimedia library of resources that are related to evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives set out in biology standards. It contains seven short videos intended for use in the classroom. They are available to stream or purchase as DVDs. Evolutionary biology is still an area of study with a lot of important questions, including what triggers evolution and how fast it happens. This is particularly applicable to human evolution where it has been difficult to reconcile the idea that the innate physical characteristics of humans were derived from apes, and the religious beliefs that hold that humans are unique among living things and holds a a special place in creation with a soul. There are a myriad of other ways in which evolution could occur and natural selection being the most well-known theory. However scientists also study different types of evolution such as genetic drift, mutation, and sexual selection, among others. While many fields of scientific study have a conflict with the literal interpretations of religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
