Evolution Site – Teaching About Evolution Despite the best efforts by biology educators, there are still a lot of misconceptions about the evolution. People who have absorbed pop science nonsense often assume that biologists don't believe in evolution. This site, which is a companion to the PBS program offers teachers resources which support evolution education, while avoiding the kinds of misconceptions which hinder it. It's organized in a “bread crumb” format to aid in navigation and orientation. Definitions It's not easy to teach evolution well. It is often misunderstood even by non-scientists, and even some scientists are guilty of using an interpretation that is confusing the issue. This is especially applicable to debates about 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 simple and efficient way. It is a companion for the 2001 series, and it is also a resource on its own. The material is presented in a structured manner that makes it simpler to navigate and comprehend. The site defines terms like common ancestor and gradual process. These terms help to define the nature of evolution and its relationship to evolution with other scientific concepts. The site also provides an overview of how the concept of evolution has been vetted and verified. This information will help to dispel the myths created by creationists. It is also possible to access a glossary of terms used in evolutionary biology. These terms include: The process of adaptation is the tendency of heritable traits to be more suitable to their environment. This is a result of natural selection, which happens when organisms that are better adapted characteristics are more likely to survive and reproduce than those with less adaptable characteristics. Common ancestor: The most recent common ancestor of two or more distinct species. By analyzing the DNA from these species, it is possible to identify the common ancestor. Deoxyribonucleic Acid: A massive biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the cause of new genetic information within cells. Coevolution is a relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or parasite and host. Origins Species (groups of individuals that can interbreed) develop through an array of natural changes in the traits of their offspring. The changes can be caused by a variety of causes that include natural selection, genetic drift, and gene pool mixing. The development of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food and habitat can slow or speed up the process. The Evolution site traces the emergence of a variety of animal and plant groups through time and focuses on the most significant transitions that occurred in the evolution of each group's history. It also examines the human evolutionary roots, a topic that is crucial for students to know. When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year after the first edition of the Origin was published, it is very unlikely that Darwin had heard or seen of it. While the site is focused on biology, it contains a wealth of information on geology and paleontology. One of the most appealing features of the website are a series of timelines which show how geological and climatic conditions changed over time, as well as an interactive map of the geographical distribution of some of the fossil groups featured on the site. The site is a companion to a PBS TV series but it could be used as a resource for teachers and students. The site is extremely well organized and provides clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler's experiments with guppies. They illustrate the importance ecology in evolutionary theory. Diversity The evolution of life on Earth has resulted in a variety of plants, animals, 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. In 에볼루션 바카라 체험 to exploring processes and events that take place frequently or over a long period of time, paleobiology allows to analyze the relative abundance of various species of organisms and their distribution throughout the course of geological time. The site is divided into various ways to learn about evolution, including “Evolution 101,” which takes the viewer on a liner path through the scientific process and the evidence to support the theory of evolution. The path also reveals common misconceptions about evolution as well as the evolution of thought. Each of the other main sections of the Evolution site is equally created, with resources that can support a variety of curriculum levels and pedagogical styles. The site has a range of multimedia and interactive resources, including videos, animations, and virtual labs in addition to general textual content. The breadcrumb-like arrangement of the content aids in navigation and orientation on the large Web site. The page “Coral Reef Connections”, for example, gives a brief overview of the coral's relationships and interactions with other organisms, and then is enlarged to show a single clam, which is able to communicate with its neighbours and respond to changes in the water conditions that occur on the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to the broad range of topics in evolutionary biology. The information also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis, which is a crucial tool for understanding the evolution of change. Evolutionary Theory Evolution is an underlying thread that is found throughout all branches of biology. A rich collection of resources supports teaching about evolution across the life sciences. One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and a variety of educational resources. The site features a wide range of interactive learning modules. It also has an encased “bread crumb” structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely linked to the field of research science. For instance an animation that introduces the notion of genetic inheritance leads to a page highlighting John Endler's artificial selection experiments with guppies from the native ponds of Trinidad. Another useful resource is the Evolution Library on this web site, which has an extensive library of multimedia resources that are related to evolution. The content is organized according to curriculum-based paths that parallel the learning goals established in biology standards. It contains seven videos specifically designed for use in the classroom, and can be streamed for free or purchased on DVD. Many important questions remain at the heart of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is particularly true for human evolution, where it has been difficult to reconcile the idea that the physical traits of humans derived from apes with religious beliefs that hold that humans are unique among living things and holds a a special place in creation with soul. There are a variety of other ways evolution could occur and natural selection being the most popular theory. Scientists also study other types such as genetic drift and sexual selection. While many fields of scientific inquiry conflict with the literal interpretations of religious texts evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, while others haven't.
