Evolution Site – Teaching About Evolution Despite the best efforts of biology educators, misinformation about evolution remain. Pop science fiction has led a lot of people to think that biologists don't believe in evolution. This rich Web site, which is a complement to the PBS program that provides teachers with resources that promote evolution education, while avoiding the kinds of misconceptions that make it difficult to understand. 에볼루션 슬롯게임 's organized in a nested “bread crumb” format to facilitate navigation and orientation. Definitions Evolution is a complex and challenging subject to teach effectively. Many non-scientists are unable to grasp the concept, and some scientists even use a definition which confuses it. This is particularly relevant to discussions on the nature of the word. Therefore, it is important to define terms used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful way. The site is both an accompaniment to the 2001 series, but it is also a resource on its own. The content is organized in a way that makes it easy to navigate and understand. The site defines terms like common ancestor and the gradual process. These terms help frame the nature of evolution and its relationship to evolution with other scientific concepts. The website provides a summary of the way the concept of evolution has been examined. This information can help dispel myths that are created by the creationists. It is also possible to find the glossary of terms used in evolutionary biology. These terms include: Adaptation is the process of changing heritable traits to become more suitable to their environment. This is the result of natural selection. Organisms with better-adapted characteristics are more likely than those with less adaptable characteristics to survive and reproduce. Common ancestor (also called common ancestor): The most recent ancestral ancestor shared by two or more species. By analyzing DNA from these species, it is possible to determine the common ancestor. Deoxyribonucleic Acid: A large 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 responsible for the creation of new genetic information within cells. Coevolution is a relationship between two species in which the evolution of one species are influenced evolutionary changes of the other. Coevolution is evident in the interactions between predator and prey, or parasites and hosts. Origins Species (groups of individuals who can interbreed) evolve through natural changes in the traits of their offspring. Changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The development of a new species can take thousands of years, and the process can be slowed down or speeded up by environmental factors like climate change or competition for food or habitat. The Evolution site tracks the evolution of various animal and plant groups through time and focuses on the most significant changes that took place in the evolution of each group's history. It also explores human evolution, which is a topic of particular importance for students. When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. While 무료 에볼루션 wasn't published until 1858, just one year before the first edition of the Origin appeared, it is very unlikely that Darwin had seen or heard of it. While the site is focused on biology, it offers a lot of information about geology as well as paleontology. Among the best features of the Web site are a set of timelines that illustrate how geological and climatic conditions have changed over time, and a map of the distribution of some fossil groups listed on the site. The site is a companion to a PBS TV series but it can also be used as an educational resource by teachers and students. The site is well-organized and provides clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features on the museum's website. These hyperlinks make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular there are hyperlinks to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory. Diversity The evolution of life on Earth has produced a diversity of animals, plants and insects. Paleobiology, the study of these creatures within their geological context offers many advantages over modern observational or research methods for studying evolutionary processes. In addition to studying the processes and events that happen frequently or over a long period of time, paleobiology can be used to examine the diversity of species of organisms and their distribution throughout the course of geological time. The Web site is divided into several optional paths to learning evolution that include “Evolution 101,” which takes the user on a linear path through the scientific process and the evidence supporting the theory of evolution. The course also focuses on common misconceptions about evolution as well as the evolution of thought. Each of the other main sections of the Evolution site is similarly developed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia resources that include animations, video clips and virtual labs in addition to general textual content. The breadcrumb-like arrangement of the content aids in navigation and orientation on the vast Web site. The page “Coral Reef Connections” For instance, the page “Coral Reef Connections” provides an overview of the coral's relationships and interactions with other organisms, and then is enlarged to show one clam that is able to communicate with its neighbours 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 website, provide an excellent introduction to a wide variety of topics in evolutionary biology. The content also includes an explanation of the role of natural selection and the concept of phylogenetic analysis, which is an important method to understand evolutionary change. Evolutionary Theory For biology students, evolution is a key thread that connects all branches of the field. A rich collection supports teaching evolution across the life science disciplines. One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of an Web site that provides depth as well as wide range of educational resources. The site offers a variety of interactive learning modules. It also has an “bread crumb structure” that assists students in moving away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely linked to the worlds of research science. For example an animation that introduces the concept of genetic inheritance links to a page highlighting 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 assets related with evolution. The contents are organized into curricula-based pathways that correspond to the learning goals established in the standards for biology. It includes seven short videos specifically designed for use in classrooms, and can be streamed for free or purchased on DVD. Evolutionary biology is an area of study that has many important questions to answer, such as what triggers evolution and the speed at which it occurs. This is especially relevant to human evolution, where it's been difficult to reconcile the notion that the physical characteristics of humans evolved from apes, and the religious beliefs that hold that humanity is unique among living things and holds a an exclusive place in the creation, with soul. In addition there are a variety of ways that evolution could occur, with natural selection being the most widely accepted theory. However, scientists also study other kinds of evolution, such as mutation, genetic drift, and sexual selection, among other things. While many scientific fields of inquiry are in conflict with the literal interpretations of the Bible evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs to evolution while others haven't.
