Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution remain. People who have absorbed pop science nonsense often assume that biologists are saying they do not believe in evolution. This site, which is a complement to the PBS program offers teachers resources that promote evolution education, while avoiding the kinds of misconceptions which hinder it. It's laid out in a “bread crumb” format to make navigation and orientation easier. Definitions Evolution is a complicated and challenging subject to teach well. It is often misunderstood by non-scientists and even some scientists use definitions that confuse the issue. This is particularly true when it comes to discussions about the meaning of the word itself. As such, it is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in a simple and efficient way. The site is both an accompaniment to the 2001 series, but also a resource on its own. The material is presented in a structured manner that makes it easier to navigate and understand. The site defines terms such as common ancestor and gradual process. 에볼루션 카지노 사이트 help 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 tested and validated. This information can be used to dispel myths that have been engendered by the creationists. It is also possible to get a glossary of terms used in evolutionary biology. These terms include: Adaptation is the tendency of hereditary traits to become better suited to an environment. This is a result of natural selection. It occurs when organisms that are better-adapted characteristics are more likely to survive and reproduce than those with less adaptable traits. Common ancestor: The latest common ancestor of two or more species. The common ancestor can be identified by studying the DNA of these species. Deoxyribonucleic acid: A massive biological molecule that contains information needed for cell replication. The information is stored in nucleotide sequences, which are strung into long chains called chromosomes. Mutations are responsible for the creation of new genetic information within 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 of individuals that are able to interbreed) change through natural changes in the characteristics of their offspring. These changes can be caused by various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of a new species can take thousands of years and the process can be slowed or increased by environmental conditions such as climate change or the competition for food or habitat. The Evolution site tracks the evolution of a number of different groups of animals and plants over time and focuses on the most significant changes that took place in each group's history. It also explores 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 bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, a year before the first edition of the Origin was published, it's extremely unlikely that Darwin had seen or heard of it. While the site focuses on biology, it also includes a good deal of information about geology and paleontology. Among the best features on the site are a series of timelines that illustrate how climatic and geological conditions have changed over time as well as an interactive map of the distribution of a few fossil groups that are featured on the site. Although the site is a companion piece to the PBS television series, it also stands on its own as a valuable source for teachers and students. The site is well-organized, and provides easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's support) and the more specific features on the museum's website. These hyperlinks help users 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. They illustrate the importance ecology in evolutionary theory. Diversity The evolution of life has resulted in an array of animals, plants and insects. Paleobiology is the study of these creatures in their geological context, has many advantages over modern observational or experimental methods of studying evolutionary phenomena. Paleobiology can examine not only processes and events that occur frequently 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 routes that can be taken to study the subject of evolution. One of the paths, “Evolution 101,” guides the user through the nature and evidence of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thought. Each of the main sections of the Evolution website is equally well-developed, and includes materials that are suited to a variety of levels of curriculum and teaching methods. The site includes a variety of multimedia and interactive resources, including videos, animations, and virtual labs in addition to general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the massive Web site. For instance, the page “Coral Reef Connections” provides an overview of the relationships between corals and their interactions with other organisms. Then, it zooms in on a single clam that can communicate with its neighbors and respond to changes in water conditions at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a broad range of topics in evolutionary biology. The material includes an explanation of the role of natural selectivity and the concept phylogenetics analysis which is a crucial method for understanding the evolution of change. Evolutionary Theory For biology students, evolution is a key thread that connects all branches of the field. A vast collection of books helps in teaching evolution across all disciplines of life sciences. One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both the depth and the breadth in terms of its educational resources. The site features a wide range of interactive learning modules. It also features an embedded “bread crumb” structure that helps students move from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the world of research science. For example an animation that introduces the idea of genetic inheritance connects to a page that highlights John Endler's artificial selection experiments with guppies from the 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 according to curricula-based paths that correspond to the learning objectives set out in the biology standards. It includes seven short videos designed specifically for use in classrooms, and can be streamed at no cost or purchased on DVD. A variety of crucial questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it happens. This is particularly true for humans' evolution which was a challenge to reconcile religious beliefs that held that humanity has a special place in the creation and a soul with the notion that human beings have innate physical traits originated from the apes. There are a variety of other ways in which evolution can take place and natural selection being the most popular theory. However scientists also study other kinds of evolution like genetic drift, mutation, and sexual selection, among other things. While many scientific fields of study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been a subject of intense debate and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, while others haven't.
