Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions persist about the evolution. Pop science nonsense has led people to believe that biologists aren't believers in evolution.
This rich Web site - companion to the PBS series It provides teachers with materials which support evolution education and avoid the kinds of myths that undermine it. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
Evolution is a complex and difficult subject matter to teach well. Non-scientists often misunderstand the subject and some scientists use a definition which confuses it. 에볼루션 슬롯 is particularly relevant when it comes to the nature of the words themselves.
Therefore, 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 manner. The site serves as an accompanying site for the 2001 series, and it is also a resource on its own. The content is organized in a way that makes it easy to navigate and comprehend.
The site defines terms such as common ancestor, gradual process and so on. These terms help to define the nature and relationship of evolution to other scientific concepts. The website provides a summary of the ways that evolution has been tested. This information can be used to dispel myths that have been propagated by the creationists.
It is also possible to find a glossary of terms that are used in evolutionary biology. These terms include:
Adaptation is the process of changing heritable traits to become more suited to the environment. This is a result of natural selection. Organisms with better-adapted traits are more likely than those with less adaptable traits to survive and reproduce.
Common ancestor (also known as common ancestor) is the most recent ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of the species.
Deoxyribonucleic Acid: A massive biological molecular containing the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the basis for new genetic information in cells.
Coevolution is a relationship between two species in which the evolution of one species are influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey or the parasite and the host.
Origins
Species (groups which can interbreed) develop through a series of natural changes in their offspring's traits. Changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food resources and habitat can impede or accelerate the process.
The Evolution site tracks the evolution of various species of plants and animals over time with a focus on the key transitions that occurred in the evolution of each group's history. It also examines the evolutionary history of humans which is especially important for students to comprehend.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. Although the skullcap was not published until 1858, a year before the first edition of the Origin appeared, it is very unlikely that Darwin had ever heard of it.
The site is primarily one of biology, but it also contains many details on paleontology and geology. Among the best features of the Web site are a set of timelines that illustrate the way in which climatic and geological conditions have changed over time, as well as an outline of the distribution of a few of the fossil groups featured on the site.
Although the site is a companion to a PBS television series but it also stands on its own as a great resource for teachers and students. The site is well-organized, and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized features of the museum's website. These hyperlinks make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are hyperlinks to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has led to a wide variety of animals, plants and insects. 에볼루션 게이밍 , the study of these creatures in their geological environment offers many advantages over the current observational or experimental methods for studying evolutionary processes. 에볼루션 바카라 무료 can examine not only the process and events that occur regularly or over time but also the distribution and frequency of various animal groups in space throughout geological time.
The site is divided into various routes that can be taken to learn about evolution. One of these paths, "Evolution 101," guides the user through the nature and evidence of evolution. The path also explores misconceptions about evolution, and also the history of evolutionary thought.
Each of the main sections of the Evolution website is equally well-designed, with materials that support a variety levels of curriculum and teaching methods. In addition to the general textual content, the site features a wide range of multimedia and interactive content, such as video clips, animations, and virtual labs. The content is presented in a nested bread crumb fashion that aids navigation and orientation within the vast Web site.
The page "Coral Reef Connections", for example, gives a brief overview of the relationships between corals and their interactions with other organisms and then zooms in on a single clam, which can communicate with its neighbors 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, provide an excellent introduction to the broad spectrum of topics in evolutionary biology. The material includes a discussion on the significance of natural selectivity and the concept of phylogenetics as a key tool to understand evolutionary changes.
Evolutionary Theory
Evolution is a common thread that connects all branches of biology. A rich collection of resources can help teachers teach about evolution across the life sciences.
One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both depth and wide range of educational resources. The site has a wide array 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 huge site that are more closely tied to the field of research science. Animation that introduces the concept of genetics, which links to a page that highlights John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.
The Evolution Library on this website contains a large multimedia library of materials that deal to evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in the standards for biology. It contains seven videos intended for use in the classroom. They can be viewed online or purchased as DVDs.
Many important questions remain at the core of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is especially true for the evolution of humans, where it was difficult to reconcile religious beliefs that humanity has a unique place in the creation and a soul with the notion that human beings have innate physical traits originated from apes.
Additionally there are a myriad of ways that evolution can occur with natural selection being the most widely accepted theory. However scientists also study other kinds of evolution like mutation, genetic drift and sexual selection, among others.
While many fields of scientific study have a conflict with the literal interpretations of religious texts, evolution biology has been a source of intense debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolution, but others haven't.
