Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misinformation about evolution persist. Pop science nonsense has led many people to believe that biologists don't believe evolution. This rich Web site, which is a companion to the PBS program that provides teachers with resources which support evolution education, while avoiding the kinds of misconceptions which make it difficult to understand. It's laid out in a “bread crumb” format to facilitate navigation and orientation. Definitions Evolution is a complicated and difficult subject to teach well. It is often misunderstood by non-scientists and even some scientists are guilty of using an interpretation that is confusing the issue. This is especially true when discussing the nature of the words themselves. It is crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful way. The site serves as an accompaniment to the 2001 series, but it is also a resource on its own. The material is presented in an organized manner that makes it simpler to navigate and comprehend. The site defines terms like common ancestor, gradual process and so on. These terms help define the nature and relationship of evolution with other scientific concepts. The site then offers an overview of how the concept of evolution has been vetted and validated. This information can be used to dispel misconceptions 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 heritable traits to be better suited to an environment. This is a result of natural selection. It occurs when organisms that have more adaptable characteristics are more likely to survive and reproduce than those with less adaptable characteristics. 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 large biological molecule that holds the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as 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 influenced by evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts. Origins Species (groups that can interbreed) develop through a series of natural changes in their offspring's traits. The changes can be triggered by a variety that include natural selection, genetic drift and mixing of genes. The evolution of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food or habitat can impede or accelerate the process. The Evolution site tracks through time the evolution of different animal and plant groups and focuses on major changes in each group's history. It also explores human evolution and is a subject of particular importance for students. Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of human beings had been discovered. One of them was the infamous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap when it was published in 1858, one year following the initial edition of The Origin. Origin. The site is mostly an online biology resource, but it also contains lots of information about geology and paleontology. One of the most appealing features of the website are a set of timelines that show how geological and climatic conditions have changed over time and an outline of the distribution of a few of the fossil groups featured on the site. The site is a companion to the PBS television series, but it could also be used as a resource by teachers and students. The site is well-organized and offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized components 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. In particular, there are links to John Endler's experiments using Guppies that 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 natural environment and has numerous advantages over the modern observational and research methods for analyzing evolutionary processes. Paleobiology can examine not only the process and events that take place regularly or over time, but also the distribution and frequency of different groups of animals in space throughout the geological time. The site is divided up into different routes that can be taken to gain knowledge about evolution. One of the paths, “Evolution 101,” walks the reader through the complexities and evidence of evolution. The path also explores common misconceptions about evolution as well as the evolution of thought. Each of the other sections of the Evolution site is equally created, with resources that can support a variety of different pedagogical levels and curriculum levels. The site offers a wide array of interactive and multimedia content, including video clips, animations and virtual laboratories as well as general textual content. The breadcrumb-like arrangement of the content aids in navigation and orientation on the vast website. For example, the page “Coral Reef Connections” provides an overview of coral relationships and their interaction with other organisms. It then narrows down to a single clam that is able to communicate with its neighbors and react to changes in water conditions at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages offers a great introduction to the many areas of evolutionary biology. 에볼루션 바카라 무료 includes a discussion of the role of natural selection and the concept of phylogenetic analysis, which is an important tool for understanding the evolution of changes. Evolutionary Theory For biology students the concept of evolution is a major thread that connects all branches of the field. A wide selection of resources helps teachers teach 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 an Web page that offers both depth and wide range of educational resources. The site offers a range of interactive learning modules. It also has a nested “bread crumb” structure that helps students move from the cartoon style of Understanding Evolution to elements on this large Web site closer to the world of research science. For instance an animation that introduces the idea of genetic inheritance connects to a page that focuses on John Endler's artificial selection experiments with guppies in native ponds of Trinidad. Another resource that is worth mentioning is the Evolution Library on this site, which has an extensive collection of multimedia resources that are related to evolution. The content is organized into curricula-based pathways that correspond to the learning objectives set out in biology standards. It contains seven short videos that are designed for use in classrooms. They can be viewed online or purchased as DVDs. Evolutionary biology is still an area of study with a lot of important questions to answer, such as what causes evolution and how fast it happens. This is particularly true for the evolution of humans, where it was difficult to reconcile religious beliefs that humanity has a unique position in the universe and a soul with the notion that our physical traits evolved from the apes. In addition there are a variety of ways that evolution can occur and natural selection is the most widely accepted theory. However, scientists also study other types of evolution such as mutation, genetic drift and sexual selection, among others. While many fields of scientific 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 notions of evolution, others have not.
