Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misinformation about evolution persist. Pop science nonsense has led people to believe that biologists don't believe evolution. This rich website – companion to the PBS series It provides teachers with materials which support evolution education and avoids the kinds of misinformation that can hinder it. It's organized in a nested “bread crumb” format to make it easy for navigation and orientation. Definitions It's not easy to teach evolution well. Non-scientists often misunderstand the subject, and some scientists even use a definition which confuses it. This is especially true when it comes to discussions about the definition of the word itself. It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient manner. The site serves as a companion for the 2001 series, and also a resource on its own. The content is presented in a way which aids navigation and orientation. The site defines terms such as common ancestor and the gradual process. These terms help to define the nature of evolution and its relation to other scientific concepts. The website then provides an overview of how the concept of evolution has been researched and validated. This information can be used to dispel the myths that have been propagated by the creationists. It is also possible to find a glossary of terms that are used in evolutionary biology. These terms include: The process of adaptation is the tendency of heritable traits to be more suitable to their environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less adapted characteristics to survive and reproduce. Common ancestor: The latest common ancestor of two or more species. By analyzing the DNA from these species it is possible to identify the common ancestor. Deoxyribonucleic acid: A massive biological molecule that contains information needed for cell replication. The information is stored in a sequence of nucleotides 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 affected by changes in evolutionary processes in the other. Coevolution can be seen through the interaction between predator and prey, or parasites and hosts. Origins Species (groups of individuals that can interbreed) change through natural changes in the characteristics of their offspring. Changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of a new species may take thousands of years, and the process may be slowed down or accelerated by environmental factors like climate change or the competition for food or habitat. The Evolution site follows the emergence of various groups of animals and plants with a focus on major changes in each group's history. It also explores human evolution as a subject that is particularly important to students. When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. 에볼루션 바카라 무료체험 of them was the infamous 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 highly unlikely that Darwin knew about the skullcap when it was published in 1858, one year after the first edition of The Origin. While the site is focused on biology, it contains a wealth of information on geology and paleontology. One of the most appealing features on the site are a series of timelines that show how climatic and geological conditions have changed over time, and an interactive map of the geographical distribution of some of the fossil groups featured on the site. The site is a companion to a PBS TV series but it can also be used as a source for teachers and students. The site is well-organized and offers clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features of the museum's website. These hyperlinks make it easy to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are links to John Endler's experiments with Guppies, which 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 geological environment is a superior method of study over modern observational or research methods for exploring evolutionary phenomena. Paleobiology can examine not just the processes and events that take place regularly or over time but also the relative abundance and distribution of different species of animals across the geological time. The site is divided up into various options to study the subject of evolution. One of these paths, “Evolution 101,” takes the viewer through the nature and evidence of evolution. The path also reveals common misconceptions about evolution and the evolution of thought. Each of the other major sections of the Evolution site is equally constructed, with materials that can be used to support a range of educational levels and pedagogical styles. The site offers a wide array of interactive and multimedia content that include animations, video clips and virtual labs, in addition to its general textual content. The content is laid out in a nested bread crumb style that facilitates navigation and orientation within the vast web site. For example, the page “Coral Reef Connections” provides an overview of coral relationships and their interactions with other organisms. It then concentrates on a specific clam that is able to communicate with its neighbours and respond to changes in the water conditions at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages gives a good introduction to many topics in evolutionary biology. The content also includes a discussion on the role of natural selectivity and the concept phylogenetics analysis as a key tool for understanding evolutionary changes. Evolutionary Theory For biology students, evolution is a key thread that connects all the branches of the field. 에볼루션 바카라 무료체험 of resources supports teaching about evolution across all life sciences. One resource, the companion to PBS's television series Understanding Evolution is an excellent example of an Web site that provides the depth and the wide range of educational resources. The site features a wealth of interactive learning modules. It also has a nested “bread crumb” structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the world of research science. An animation that introduces the concept of genetics links to a page highlighting John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad. The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in biology standards. It contains seven videos specifically designed for classroom use, which can be streamed for no cost or purchased on DVD. Evolutionary biology is an area of study that poses many important questions, including what causes evolution and how fast it takes place. This is particularly relevant to human evolution, where it has been difficult to reconcile the notion that the physical traits of humans derived from apes, and the religious beliefs that hold that humans are unique among living things and holds a an exclusive place in the creation. It is a soul. There are a myriad of other ways in which evolution can take place and natural selection being the most well-known theory. Scientists also study different types like mutation, genetic drift and sexual selection. Many fields of inquiry are in conflict with literal interpretations of religious texts evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, but others haven't.
