Evolution Site – Teaching About Evolution Despite the best efforts by biology educators, there are still a lot of misconceptions about evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution. This site, a companion to the PBS program offers teachers resources that promote evolution education, while avoiding the kinds of misconceptions which undermine it. It's organized in a nested “bread crumb” format for ease of navigation and orientation. Definitions Evolution is a complicated and difficult 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 debates about the nature of the word. Therefore, it is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful way. The website is a companion to the show which first aired in 2001, but it is also an independent resource. The material is presented in an organized way that makes it easy to navigate and comprehend. The site defines terms like common ancestor, gradual process and so on. These terms help to frame the nature of evolution and its relationship to other concepts in science. The website provides a summary of the way in which evolution has been examined. This information will help to dispel the myths created by creationists. You can also access a glossary which includes terms used in evolutionary biology. These terms include: Adaptation is the process of changing hereditary traits to become better suited to an environment. This is a 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: The most recent common ancestor of two or more species. The common ancestor can be identified through analyzing the DNA of these species. Deoxyribonucleic Acid: A huge biological molecular containing the necessary information for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, called chromosomes. Mutations are the basis for new genetic information in cells. Coevolution: A relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts. Origins Species (groups which can interbreed), evolve through a series natural changes in their offspring's traits. The changes can be caused by a variety of factors that include natural selection, genetic drift, and mixing of gene pools. The evolution of new species can take thousands of years. Environmental conditions, such as climate change or competition for food and habitat can slow or speed up the process. The Evolution site tracks the development of a number of different animal and plant groups through time, focusing on the major changes that took place in each group's history. It also focuses on the evolutionary origin of humans, a topic that is particularly important for students to know. When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. Among them was the famous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. 에볼루션 무료 바카라 is unlikely that Darwin was aware of the skullcap when it was published in 1858, which was a year after the publication of the first edition of The Origin. The site is mostly an online biology resource however it also includes many details on paleontology and geology. The Web site has several features that are especially impressive, including an overview of how geological and climate conditions have changed over the course of time. It also includes a map showing the distribution of fossil groups. While the site is a companion piece to the PBS television series, it also stands on its own as an excellent source for teachers and students. The site is well organized and provides clear links between the introduction content 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 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 led to an array of plants, animals and insects. Paleobiology is the study of these creatures in their geological context and has numerous advantages over modern observational and experimental methods of examining evolutionary processes. In addition to examining the processes and events that happen regularly or over a lengthy period of time, paleobiology allows to examine the diversity of kinds of organisms as well as their distribution in space over the course of geological time. The Web site is divided into several optional paths to learning evolution which include “Evolution 101,” which takes the viewer on a liner path through the scientific process and the evidence supporting the theory of evolution. The course also focuses on misconceptions about evolution and the background of evolutionary thought. Each of the other major sections of the Evolution site is equally well constructed, with materials that can be used to support a range of curriculum levels and pedagogical styles. The site has a range of multimedia and interactive resources, including animations, video clips and virtual labs, in addition to its general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the vast web site. The page “Coral Reef Connections” For instance, it provides a comprehensive overview of the relationships between corals, their interaction with other organisms and zooms in on a single clam, which is able communicate with its neighbors and respond to changes in conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a crucial tool in understanding evolutionary change. Evolutionary Theory For biology students the concept of evolution is a major thread that binds all the branches of the field. A vast collection of books helps in teaching evolution across the disciplines of life science. One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth as well as wide range of educational resources. The site features a wealth of interactive learning modules. It also has an “bread crumb structure” that allows students to move away from the cartoon-like style used in Understanding Evolution and onto elements on this site that are more closely connected to the worlds of research science. Animation that introduces the concept of genetics links to a page about John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad. The Evolution Library on this website contains a large multimedia library of assets related to evolution. The contents are organized into courses that are based on curriculum and follow the learning objectives outlined in the biology standards. It contains seven videos designed for use in classrooms. These are available to stream or purchase as DVDs. Evolutionary biology is an area of study that has many important questions, such as what causes evolution and how fast it happens. This is especially relevant to human evolution, where it's been difficult to reconcile the notion that the physical traits of humans were derived from apes, and the religious beliefs that claim that humanity is unique among living things and has an enviable place in creation with soul. Additionally there are a myriad of ways that evolution could be triggered with natural selection being the most popular theory. Scientists also study other types such as genetic drift, and sexual selection. While many scientific fields of inquiry are in conflict with literal interpretations of the Bible evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Certain religions have reconciled their beliefs to evolution while others haven't.
