Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misinformation about evolution remain. Pop science fiction has led a lot of people to believe that biologists aren't believers in evolution. This rich Web site – companion to the PBS series offers teachers with resources which support evolution education and help avoid the kinds of myths that hinder it. It's laid out in the “bread crumb” format to facilitate navigation and orientation. Definitions It's difficult to teach evolution well. Many non-scientists are unable to grasp the concept, and some scientists even use a definition which confuses it. This is particularly relevant to discussions about the nature of the word. It is crucial to define the terms used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful manner. It is a companion for the 2001 series, and also a resource on its own. 에볼루션 슬롯 Evolution is organized in a manner that makes it simpler to navigate and comprehend. The site defines terms such as common ancestor, gradual process and adaptation. These terms help to define the nature and relationship of evolution to other scientific concepts. The site provides an overview of the manner that evolution has been tested. This information can be used to dispel the myths that have been engendered 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 for heritable traits to become better adaptable to a specific environment. This is due to natural selection, which happens when organisms that are better adapted traits are more likely to survive and reproduce than those with less adapted characteristics. Common ancestor: The latest common ancestor of two or more different species. By analyzing the DNA from these species, it is possible to identify the common ancestor. Deoxyribonucleic Acid: A large biological molecular that holds the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are the source of new genetic information in cells. Coevolution is a relationship between two species, where the evolutionary changes of one species are influenced evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or host and parasite. Origins Species (groups of individuals that are able to interbreed) develop through natural changes in the characteristics of their offspring. These changes are caused by a variety that include natural selection, genetic drift and mixing of genes. The development of a new species can take thousands of years and the process may be slowed down or speeded up due to environmental conditions, such as climate change or competition for food or habitat. The Evolution site traces the emergence of a number of different animal and plant groups through time with a focus on the key changes that took place in each group's history. It also focuses on human evolution as a subject that is of particular interest for students. When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. One of them was the infamous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year before the first edition of the Origin was published, it's highly unlikely that Darwin had seen or heard of it. The site is mostly an online biology resource however it also includes lots of information about paleontology and geology. The site offers several aspects that are quite impressive, including an overview of the way that climate and geological conditions have changed over time. It also includes maps that show the locations of fossil groups. Although the site is a companion piece to a PBS television series however, it can stand on its own as a valuable resource for teachers and students. The site is well organized and provides clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks help users move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's experiments using Guppies, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has led to a wide variety of animals, plants 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 processes. In addition to studying processes and events that occur frequently or over a long period of time, paleobiology is able to examine the relative abundance of different kinds of organisms as well as their distribution in space over the geological time. The site is divided into different options to study the subject of evolution. One of these paths, “Evolution 101,” walks the reader through the evolution of nature and the evidence of evolution. The course also focuses on common misconceptions about evolution and the history of evolutionary thought. Each of the main sections of the Evolution website is equally well-designed, with materials that can be used to support a variety of educational levels and teaching styles. The site has a range of multimedia and interactive resources which include animations, video clips and virtual laboratories, in addition to its general textual content. The content is presented in a nested bread crumb fashion that aids 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 narrows down to a single clam that is able to communicate with its neighbors and react 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 information also includes an explanation of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool in understanding evolutionary changes. Evolutionary Theory For biology students evolution is a crucial thread that connects all branches of the field. A rich collection supports teaching evolution across all disciplines of life sciences. One resource, which is the companion to PBS's television show 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 nested “bread crumb” structure that helps students transition from the cartoon style of Understanding Evolution to elements on this massive website that are more closely linked to the world of research science. An animation that introduces the concept of genetics is linked to a page about John Endler's experiments in artificial selection using guppies on native ponds in Trinidad. The Evolution Library on this website has a huge multimedia library of materials that deal with evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives outlined in the standards for biology. It includes seven short videos that are designed for classroom use. These are available to stream or purchase as DVDs. 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 especially true for human evolution, where it has been difficult to reconcile that the physical characteristics of humans derived from apes, and the religious beliefs that hold that humanity is unique among living things and has a special place in creation. It is a soul. There are a variety of other ways evolution can take place, with natural selection as the most well-known theory. Scientists also study other kinds such as mutation, genetic drift, and sexual selection. While many scientific fields of inquiry have a conflict with literal interpretations of the Bible, evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the ideas of evolution, others aren't.
