Evolution Site – Teaching About Evolution Despite the best efforts of biology teachers, there are still misconceptions about the evolution. Pop science nonsense has led many people to think that biologists don't believe in evolution. This rich website – companion to the PBS series It provides teachers with materials which support evolution education and avoid the kinds of misinformation that can undermine it. It's laid out in a nested “bread crumb” format to facilitate navigation and orientation. Definitions Evolution is a complicated and difficult subject matter to teach effectively. Non-scientists often misunderstand the subject and some scientists use a definition which confuses it. This is especially true when it comes to discussions on the nature of the word. It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. It is an accompaniment to the 2001 series, and also a resource on its own. The material is presented in a nested manner that aids navigation and orientation. The site defines terms like common ancestor, the gradual process and adaptation. These terms help frame the nature and relationship of evolution with other scientific concepts. The site gives a comprehensive overview of the manner that evolution has been tested. This information can help dispel myths created by creationists. You can also consult a glossary that contains terms used in evolutionary biology. These terms include: Adaptation: The tendency of hereditary traits to become more suited to a particular environment. This is a result of natural selection, which occurs when organisms that have better adapted characteristics are more likely to survive and reproduce than those with less adapted traits. 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 large biological molecular that contains the information needed for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the cause of new genetic information in 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 parasite and hosts. Origins Species (groups that can interbreed), evolve through a series of natural changes in the traits of their offspring. The changes can be triggered by a variety of causes that include natural selection, genetic drift, and mixing of gene pools. The development of new species can take thousands of years. Environmental conditions, such as climate change or competition for food or habitat can impede or accelerate the process. The Evolution site tracks the development of a number of different animal and plant groups through time with a focus on the key transitions that occurred in the history of each group. It also examines the evolution of humans and is a subject that is particularly important to students. When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The famous skullcap, with the bones that accompanied it, was 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 was aware of the skullcap, which was published in 1858, a year after the publication of the first edition of The Origin. While the site is focused on biology, it also contains a wealth of information on geology and paleontology. The Web site has numerous aspects that are quite impressive, including the timeline of the way that climate and geological conditions have changed over time. It also features an interactive map that shows the location of fossil groups. The site is a companion for the PBS television series, but it could also be used as an educational resource for teachers and students. The site is well-organized, and provides clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features of the museum's website. These links facilitate the transition 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 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, the study of these creatures in their geological environment, has many advantages over the current observational or experimental methods of studying evolutionary phenomena. Paleobiology is able to study not just the processes and events that happen frequently or over time, but also the relative abundance and distribution of different species of animals in space over the course of geological time. The Web site is divided into several optional ways to learn about evolution which include “Evolution 101,” which takes the user on a linear path through the nature of science and the evidence that supports the theory of evolution. The course also focuses on misconceptions about evolution and the background of evolutionary thinking. Each of the other major sections of the Evolution site is equally developed, with materials that can support a variety of different pedagogical levels and curriculum levels. The site includes a variety of interactive and multimedia resources, including video clips, animations and virtual labs as well as general textual content. The breadcrumb-like arrangement of the content helps with navigation and orientation on the vast Web site. For instance the page “Coral Reef Connections” gives a brief overview of coral relationships and their interaction with other organisms. Then, it concentrates on a specific clam that can communicate with its neighbors and respond to changes in the water conditions that occur at the level of the reef. This page, along with the other multidisciplinary multimedia and interactive pages, provides an excellent introduction to the many areas of evolutionary biology. The content also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is a key tool for understanding the evolution of changes. Evolutionary Theory For biology students evolution is a crucial thread that connects all branches of the field. A rich collection of resources helps teachers teach about evolution across all life sciences. 에볼루션 무료 바카라 , which is a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that offers both depth and a variety of educational resources. The site offers a range of interactive learning modules. It also has an encased “bread crumb” structure that allows students to move from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the field of research science. Animation that introduces the concept of genetics links to a page about John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad. The Evolution Library on this website contains a large multimedia library of assets related with evolution. The content is organized in curricula-based paths that correspond to the learning objectives set out in the standards for biology. It includes seven short videos specifically designed for classroom use. They can be viewed online or purchased as DVDs. A number of important questions remain in the midst of evolutionary biology, such as the factors that trigger evolution and how fast it happens. This is particularly applicable to human evolution which has made it difficult to reconcile the idea that the physical characteristics of humans evolved from apes and religious beliefs that hold that humanity is unique among living things and has a special place in creation, with a soul. In 에볼루션 사이트 , there are a number of ways in which evolution could be triggered and natural selection is the most popular theory. However scientists also study different kinds of evolution like genetic drift, mutation, and sexual selection, among others. Many fields of inquiry conflict with literal interpretations of the Bible evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, but others haven't.
