Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misconceptions about evolution persist. Pop science nonsense has led many people to believe that biologists aren't believers in evolution. This site, a companion to the PBS program that provides teachers with resources which support evolution education while avoiding the types of misconceptions which hinder it. It's laid out in a “bread crumb” format to make navigation and orientation easier. Definitions It's difficult to effectively teach evolution. It is often misunderstood by non-scientists and even some scientists have been guilty of using a definition that confuses the issue. This is particularly applicable to debates about the definition of the word itself. Therefore, it is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful way. The site is both a companion for the 2001 series, but also a resource on its own. The material is presented in a way that aids navigation and orientation. The site defines terms such as common ancestor, the gradual process and adaptation. These terms help frame the nature of evolution as well as its relation to other concepts in science. The site then offers an overview of how the concept of evolution has been researched and validated. This information can help dispel the myths created by creationists. 에볼루션 블랙잭 is also possible to find the glossary of terms used in evolutionary biology. These terms include: Adaptation: The tendency of heritable traits to become better suitable to a particular setting. This is a result of natural selection. It occurs when organisms that have better-adapted traits are more likely 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 through analyzing the DNA of the species. Deoxyribonucleic acid: A massive biological molecule that holds the information needed for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are the reason behind 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. Examples of coevolution include the interactions between predator and prey or host and parasite. Origins Species (groups of individuals that are able to interbreed) change through a series of natural changes in the characteristics of their offspring. These changes are caused by a variety of causes such as natural selection, genetic drift, and mixing of gene pools. The development of new species can take thousands of years. Environmental conditions, like changes in the climate or competition for food and habitat, can slow or accelerate the process. The Evolution site tracks the evolution of various animal and plant groups through time and focuses on the most significant shifts that occurred throughout each group's history. It also explores human evolution and is a subject of particular importance to students. Darwin's Origin was published in 1859, when just a few antediluvian fossils of humans had been found. Among them was the famous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was published in 1858, one year after the publication of the first edition of The Origin. The site is mostly one of biology however, it also has lots of information about geology and paleontology. Among the best features of the Web site are a timeline of events which show the way in which climatic and geological conditions have changed over time and an outline of the distribution of a few fossil groups that are featured on the site. Although the site is a companion to the PBS television series however, it can stand on its own as a great resource for teachers and students. The site is very well-organized and offers clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are links to John Endler's experiments using Guppies, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life has led to an array of animals, plants and insects. Paleobiology is the study of these creatures within their geological context and has numerous advantages over the current observational and experimental methods in its exploration of evolutionary processes. In addition to examining the processes and events that happen regularly or over a long period of time, paleobiology allows to examine the relative abundance of different kinds of organisms as well as their distribution in space over geological time. The site is divided into various options to gain knowledge about evolution. One of the paths, “Evolution 101,” walks the reader through the complexities and evidence of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought. Each of the other sections of the Evolution site is equally well created, with resources that support a variety of educational levels and pedagogical styles. The site offers a wide array of multimedia and interactive resources, including animations, video clips and virtual laboratories as well as general textual content. The content is organized in a nested, bread crumb style that facilitates navigation and orientation within the vast web site. For instance, the page “Coral Reef Connections” gives a brief overview of coral relationships and their interaction with other organisms. It then narrows down to a single clam that can communicate with its neighbors and respond to changes in water conditions that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great introduction to many topics in evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis, which is an important method to understand evolutionary changes. Evolutionary Theory For biology students evolution is a crucial thread that binds all the branches of the field. A vast collection of resources can help teachers teach about evolution across all life sciences. One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that provides the depth and breadth of its educational resources. The site features a wealth of interactive learning modules. It also has a nested “bread crumb” structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. For example an animation that explains the idea of genetic inheritance connects to a page that highlights John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad. The Evolution Library on this website contains a large multimedia library of resources that are associated with evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in biology standards. It contains seven short videos that are intended for use in the classroom. These can be viewed online or purchased as DVDs. Evolutionary biology remains a field of study that has many important questions, including what triggers evolution and how quickly it takes place. This is particularly true for human evolution, where it's been difficult to reconcile the notion that the physical traits of humans were derived from apes, and the religions that believe that humanity is unique among living things and has an exclusive place in the creation, with a soul. There are a myriad of other ways in which evolution can occur and natural selection being the most widely accepted theory. Scientists also study other types such as mutation, genetic drift and sexual selection. While many scientific fields of inquiry are in conflict with the literal interpretations of the Bible evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, but others haven't.
