Evolution Site – Teaching About Evolution Despite the best efforts by biology educators, misconceptions persist about evolution. People who have taken in popular science myths often assume that biologists are saying they don't believe in evolution. This rich Web site, a companion to the PBS program that provides teachers with resources that promote evolution education, while avoiding the kinds of misconceptions which hinder it. It's laid out in a nested “bread crumb” format to make it easy for navigation and orientation. Definitions It's not easy to properly teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition that confuses it. This is especially relevant when it comes to the meaning of the words themselves. It is therefore important 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 manner. The website is a companion to the series that first aired in 2001, but it can also function as an independent resource. The material is presented in a structured manner that makes it easier to navigate and comprehend. The site defines terms such as common ancestor, the gradual process and adaptation. These terms help to define the nature of evolution and its relationship to evolution to other scientific concepts. The website then provides an overview of how the concept of evolution has been researched and verified. This information can help dispel myths that are created by the creationists. You can also consult a glossary that contains terms that are used in evolutionary biology. These terms include: The process of adaptation is the tendency of hereditary traits to become more suitable to their environment. This is a result of natural selection. Organisms with more adaptable traits are more likely than those with less adaptable characteristics to survive and reproduce. Common ancestor (also called common ancestor) The most recent ancestor that is shared by two or more species. By analyzing DNA from these species it is possible to determine the common ancestor. Deoxyribonucleic Acid: A huge biological molecular containing the necessary information for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells. Coevolution is a relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. 에볼루션카지노사이트 of coevolution include the interaction between predator and prey or the parasite and the host. Origins Species (groups that can crossbreed) change by a series of natural variations in their offspring's traits. The causes of these changes are numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental circumstances, such as climate changes or competition for food and habitat, can slow or accelerate the process. The Evolution site follows the evolution of different animal and plant groups and focuses on major changes in each group's past. It also examines the evolutionary origin of humans, a topic that is crucial for students to comprehend. Darwin's Origin was published in 1859, at a time when only a few antediluvian fossils of humans were discovered. The famous skullcap, with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was published in 1858, one year following the initial edition of The Origin. Origin. The site is mostly an online biology resource however it also includes lots of information about paleontology and geology. The site offers a number of features that are particularly impressive, including an overview of how geological and climate conditions have changed over time. It also features a map showing the distribution of fossil groups. The site is a companion for a PBS TV series but it could also be used as an educational resource by teachers and students. The site is well-organized and provides easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features on the museum's website. These hyperlinks make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler's experiments with guppies. They illustrate the importance of ecology in evolutionary theory. Diversity The evolution of life has produced a variety of plants, animals and insects. Paleobiology is the study of these creatures in their geological environment offers many advantages over modern observational or research methods for exploring evolutionary phenomena. Paleobiology is able to study not only processes and events that occur regularly or over time but also the relative abundance and distribution of various animal groups across the geological time. The site is divided up into various options to gain knowledge about evolution. One of these paths, “Evolution 101,” walks the reader through the nature and evidence of evolution. The path also explores misconceptions about evolution, and also the history of evolutionary thinking. Each of the main sections on the Evolution website is equally well-designed, with materials that are suited to a variety of curriculum levels and teaching styles. In addition to the general textual content, the site also has a wide range of multimedia and interactive content including videos, animations and virtual laboratories. The content is laid out in a nested bread crumb style that facilitates navigation and orientation within the large Web site. The page “Coral Reef Connections” For instance, it provides an overview of the coral's relationships and interactions with other organisms and zooms in to one clam that can communicate with its neighbours and respond to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great introduction to a variety 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 a crucial tool for understanding the evolution of changes. Evolutionary Theory Evolution is a common thread that runs through all branches of biology. A rich collection of resources helps teachers teach about evolution across the life sciences. One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that offers both depth and wide range of educational resources. The site has a variety of interactive learning modules. It also has a “bread crumb structure” that assists students in moving away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely connected to the worlds of research science. Animation that introduces the concept of genetics, which links to a page that highlights John Endler's experiments with artificial selection using Guppies in native ponds in Trinidad. The Evolution Library on this website is a vast multimedia library of materials that deal to evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in the standards for biology. It contains seven short videos specifically intended for use in the classroom. They can be viewed online or purchased as DVDs. A variety of crucial questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is particularly relevant for the evolution of humans which was a challenge to reconcile religious beliefs that held that humanity has a unique place in creation and a soul, with the notion that our physical traits were derived from the apes. There are also a number of other ways evolution can take place, with natural selection as the most well-known theory. However scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among other things. Although many scientific fields of study conflict with the literal interpretations of religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, other religions haven't.
