Evolution Site - Teaching About Evolution
Despite the best efforts by biology teachers, there are still misconceptions regarding evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.
This site, which is a complement to the PBS program offers teachers resources that promote evolution education, while avoiding the kinds of misconceptions that undermine it. It's laid out in the "bread crumb" format to make navigation and orientation easier.
Definitions
It's not easy to teach evolution well. It is often misunderstood by non-scientists, and even some scientists are guilty of using a definition that confuses the issue. This is especially relevant when it comes to the nature of the words themselves.
As such, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site serves as an accompaniment to the 2001 series, but also a resource of its own. The material is presented in a nested fashion which aids navigation and orientation.
The site defines terms such as common ancestor, gradual process, and adaptation. These terms help define the nature and significance of evolution to other scientific concepts. The site also provides an overview of how the concept of evolution has been vetted and confirmed. 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:
Adaptation: The tendency of heritable characteristics to become more suited to a particular environment. This is a result of natural selection. Organisms with more adaptable characteristics are more likely than those with less-adapted characteristics to survive and reproduce.
Common ancestor (also called common ancestor) is the most recent ancestor that is shared by two or more species. By analyzing DNA from these species, it is possible to identify the common ancestor.
Deoxyribonucleic Acid: A large biological molecular containing the information required for cell replication. The information is contained in a sequence of nucleotides that are strung together to form long chains, called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.
Coevolution is a relationship between two species where evolution of one species are influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or host and parasite.
Origins
Species (groups that can crossbreed) develop through a series of natural changes in the traits of their offspring. These changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The development of a new species could take thousands of years and the process may 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, focusing on the major transitions that occurred in the evolution of each group's history. 무료 에볼루션 explores human evolution and is a subject that is particularly important to students.
Darwin's Origin was published in 1859, at a time when only a few antediluvian fossils of humans were discovered. One of them was the infamous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, a year before the first edition of the Origin was published, it is highly unlikely that Darwin had heard or seen of it.
While the site focuses on biology, it also includes a good deal of information about geology and paleontology. The site offers numerous aspects that are quite impressive, such as an overview of how climate and geological conditions have changed over time. It also features a map showing the distribution of fossil groups.
The site is a companion to the PBS TV series but it can also be used as an educational resource by teachers and students. The site is well-organized and has clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These links 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. They demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has resulted in a variety of animals, plants and insects. Paleobiology, the study of these creatures within their geological context is a superior method of study over the current observational or experimental methods for exploring evolutionary processes. Paleobiology focuses on not only the process and events that occur regularly or over time, but also the relative abundance and distribution of different species of animals in space over the course of geological time.
The Web site is divided into a variety of ways to learn about evolution, including "Evolution 101," which takes the viewer on a line through the science of nature and the evidence that supports the theory of evolution. The path also examines myths about evolution and also the history of evolutionary thought.
Each of the other main sections of the Evolution site is similarly created, with resources that support a variety of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia content, including videos, animations, and virtual labs in addition to general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the vast web site.
The page "Coral Reef Connections", for example, provides an overview of the coral's relationships, their interaction with other organisms and then zooms in to one clam, which is able to communicate with its neighbors and react to changes in conditions of the water at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, offers a great introduction to a variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis, which is an important tool in understanding evolutionary change.
Evolutionary Theory
For biology students, evolution is a key thread that weaves together all branches of the field. A wide selection of resources helps teachers teach evolution across all life science disciplines.
One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides depth and a variety of educational resources. 에볼루션 무료 바카라 has a variety of interactive learning modules. It also has a nested "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the field of research science. Animation that introduces the concept of genetics links to a page that highlights John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.
Another useful resource is the Evolution Library on this website, which includes an extensive collection of multimedia items connected to evolution. The contents are organized into curriculum-based paths that parallel the learning objectives set out in the biology standards. It contains seven short videos designed for classroom use. These can be viewed online or purchased as DVDs.
Evolutionary biology is an area of study that poses many important questions to answer, such as what triggers evolution and how fast it happens. This is particularly true for humans' evolution where it was a challenge to reconcile religious beliefs that humanity has a special position in the universe and a soul with the idea that innate physical traits evolved from the apes.
In addition there are a variety of ways that evolution could occur, with natural selection being the most widely accepted theory. Scientists also study other kinds like mutation, genetic drift and sexual selection.
Although many scientific fields of study are in conflict with literal interpretations in religious texts, the concept of evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, other religions have not.
