Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution persist. Pop science fiction has led a lot of people to think that biologists don't believe in evolution. This rich website – companion to the PBS series offers teachers with resources which support evolution education and avoids the kinds of myths that hinder it. It's laid out in a nested “bread crumb” format for ease of navigation and orientation. Definitions Evolution is a complicated and difficult subject matter to teach well. It is often misunderstood by non-scientists and even some scientists have been guilty of using an interpretation that is confusing the issue. This is especially relevant when discussing the meaning of the words themselves. It is therefore important to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient manner. 에볼루션 룰렛 is a companion to the series that first aired in 2001, but it is also an independent resource. The information is organized in a manner that makes it simpler to navigate and comprehend. The site defines terms like common ancestor, the gradual process, and adaptation. These terms help to define the nature and relationship of evolution with other scientific concepts. The website then provides an overview of how the concept of evolution has been vetted and confirmed. This information can be used to dispel misconceptions that have been propagated by the creationists. You can also access a glossary that contains terms used in evolutionary biology. These terms include: Adaptation is the process of changing heritable traits to be better suited to an environment. This is due to natural selection, which occurs when organisms with better-adapted traits are more likely survive and reproduce than those with less adaptable traits. Common ancestor (also known as common ancestor) is the most recent ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of the species. Deoxyribonucleic Acid: A massive biological molecular that holds the information required for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the source of new genetic information in cells. Coevolution is the relationship between two species where evolutionary changes of one species are influenced by evolutionary changes in the other. Coevolution is evident in the interactions between predator and prey, or parasite and hosts. Origins Species (groups of individuals that can interbreed) evolve through a series of natural changes in the traits of their offspring. These changes are caused by a variety of causes that include natural selection, genetic drift and mixing of genes. The development of a new species may take thousands of years and the process can be slowed down or accelerated due to environmental conditions, such as climate change or the competition for food or habitat. The Evolution site traces the emergence of a number of different species of plants and animals over time, focusing on the major changes that took place in the history of each group. It also focuses on the evolutionary origin of humans which is particularly important for students to comprehend. Darwin's Origin was published in 1859, at a time when only a few antediluvian fossils of humans were discovered. Among them was the famous skullcap and the associated bones 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, one year before the first edition of the Origin was published, it is extremely unlikely that Darwin had seen or heard of it. The site is primarily one of biology however it also includes many details on geology and paleontology. The site offers numerous features that are especially impressive, such as a timeline of how climate and geological conditions have changed over time. It also has an interactive map that shows the location of fossil groups. The site is a companion to a PBS television series, but it can also be used as a resource for teachers and students. The site is well-organized and offers clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features of the museum's website. These hyperlinks make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds 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 has produced many species of animals, plants and insects. Paleobiology is the study of these creatures within their geological context and has a number of advantages over the modern observational and research methods of examining evolutionary processes. Paleobiology can examine not only processes and events that occur regularly or over time but also the distribution and frequency of various animal groups in space over the course of the geological time. The site is divided into various pathways to understanding evolution which include “Evolution 101,” which takes the viewer on a line through the scientific process and the evidence to support the theory of evolution. The course also focuses on misconceptions regarding evolution, as well as 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 educational levels and teaching styles. The site has a range of interactive and multimedia content that include video clips, animations and virtual labs, in addition to its general textual content. The breadcrumb-like organization of the content aids in navigation and orientation on the vast Web site. The page “Coral Reef Connections” For instance, it gives a brief overview of the relationships between corals and their interactions with other organisms and then zooms in on a single clam, which is able communicate with its neighbours and respond to changes in water conditions that occur on 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 information also includes an overview of the importance of natural selection and the concept of phylogenetic analysis, which is an important method to understand evolutionary changes. Evolutionary Theory Evolution is an underlying thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life sciences. One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both depth and breadth in its educational resources. The site features a wealth of interactive learning modules. It also has a “bread crumb structure” that helps students move away from the cartoon-like style used in Understanding Evolution and onto elements on this large website more closely connected to the fields of research science. An animation that introduces the concept of genetics is linked to a page about John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad. The Evolution Library on this website has a huge multimedia library of resources that are associated with evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives set out in the biology standards. It contains seven videos specifically designed for use in the classroom, and can be streamed for free or purchased on DVD. A variety of crucial questions remain at the core of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is especially true for humans' evolution, where it was difficult to reconcile religious beliefs that held that humanity has a special place in creation and a soul, with the idea that innate physical traits evolved from Apes. In addition, there are a number of ways that evolution could occur with natural selection being 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 conflict with literal interpretations of religious texts, evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
