Evolution Site – Teaching About Evolution Despite the best efforts of biology teachers, there are still misconceptions about the evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution. This site, which is a companion to the PBS series It provides teachers with materials that support evolution education and avoids the kinds of misconceptions that make it difficult to understand. It's laid out in a nested “bread crumb” format to facilitate navigation and orientation. Definitions It's difficult to effectively teach evolution. 에볼루션 바카라 무료 who are not scientists often have a difficult time understanding the subject and some scientists use a definition that confuses it. This is especially true when it comes to debates about the definition of the word itself. As such, it is essential to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this 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 an organized manner that makes it easier to navigate and comprehend. The site defines terms such as common ancestor and gradual process. These terms help to define the nature and relationship of evolution with other scientific concepts. The site also provides an overview of how the concept of evolution has been vetted and confirmed. This information can be used to dispel myths that have been engendered by the creationists. You can also consult a glossary that contains terms that are used in evolutionary biology. These terms include: 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 characteristics are more likely than those with less adaptable traits to survive and reproduce. Common ancestor (also known as common ancestor) is the most recent ancestor that is shared by two or more species. By studying the DNA of these species it is possible to determine the common ancestor. Deoxyribonucleic acid: A massive biological molecule that contains information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, called chromosomes. Mutations are responsible for the creation of new genetic information inside cells. Coevolution is a relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey, or host and parasite. Origins Species (groups which can interbreed) change through a series of natural changes in the traits of their offspring. The changes can be caused by a variety such as natural selection, genetic drift, and mixing of genes. The evolution of new species could take thousands of years. Environmental conditions, like climate changes or competition for food or habitat can slow or speed up the process. The Evolution site traces the emergence of a variety of groups of animals and plants over time and focuses on the most significant transitions that occurred in each group's history. It also examines the evolutionary history of humans which is crucial for students to comprehend. When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. Among them was the famous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, which was a year following the initial edition of The Origin. Origin. The site is primarily an online biology resource however it also includes lots of information about geology and paleontology. One of the most appealing features of the website are a timeline of events which show how geological and climatic conditions changed over time, and an interactive map of the distribution of a few fossil groups listed on the site. While the site is a companion to the PBS television show however, it can stand on its own as an excellent resource for teachers and students. The site is well-organized and offers clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features on the museum's website. These links facilitate the transition from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler’s experiments with guppies, which illustrate the importance ecology in evolutionary theory. Diversity The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology is the study of these creatures within their geographical context and offers a number of advantages over the current observational and experimental methods of examining evolutionary processes. Paleobiology is able to study not just the processes and events that occur 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 into different routes that can be taken to gain knowledge about evolution. One of the paths, “Evolution 101,” takes the viewer through the nature and evidence of evolution. The path also examines myths regarding evolution, as well as the history of evolutionary thought. Each of the other sections of the Evolution site is similarly created, with resources that can support a variety of educational levels and pedagogical styles. The site offers a wide array of interactive and multimedia content that include videos, animations, and virtual laboratories as well as general textual content. The breadcrumb-like organization of the content aids in navigation and orientation on the massive Web site. The page “Coral Reef Connections” For instance, the page “Coral Reef Connections” gives a brief overview of the relationships between corals, their interaction with other organisms and zooms in to one clam, which is able to communicate with its neighbors and respond to changes in the conditions of the water at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a wide spectrum of topics in evolutionary biology. The material includes an overview of the role of natural selectivity and the concept of phylogenetics as a key tool to understand evolutionary changes. Evolutionary Theory Evolution is a common thread that connects all branches of biology. A rich collection of resources can help teachers teach about evolution across the 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 as well as wide range of educational resources. The site features a wide range of interactive learning modules. It also features an embedded “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 world of research science. For example an animation that explains the concept of genetic inheritance links to a page that highlights John Endler's experiments in artificial selection using guppies in the ponds of his native country of Trinidad. Another resource that is worth mentioning is the Evolution Library on this Web site, which contains an extensive library of multimedia items connected to evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in the standards for biology. It contains seven videos that are intended for use in the classroom. They can be viewed online or purchased as DVDs. Evolutionary biology is a field of study with a lot of important questions to answer, such as what causes evolution and how quickly it occurs. This is particularly relevant to human evolution, where it has been difficult to reconcile the notion that the innate physical characteristics of humans were derived from apes and religious beliefs that claim that humanity is unique in the universe and has an enviable place in creation, with a soul. There are a myriad of other ways evolution could occur and natural selection being the most well-known theory. However scientists also study other kinds of evolution like genetic drift, mutation, and sexual selection, among other things. While many fields of scientific study conflict with literal interpretations in religious texts, the concept of evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, others have not.
