Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution persist. People who have taken in pop science nonsense often assume that biologists are saying they don't believe in evolution.
This rich Web site, which is a companion to the PBS program that provides teachers with resources which support evolution education, while avoiding the kinds of misconceptions that can undermine it. It's laid out in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
It's difficult to effectively teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. 에볼루션 무료체험 is especially applicable to debates about the meaning of the word itself.
It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site is both an accompaniment to the 2001 series, but also a resource on its own. The material is presented in a nested fashion that aids navigation and orientation.
The site defines terms such as common ancestor, gradual process and so on. These terms help to define the nature of evolution and its relation to other scientific concepts. The website provides a summary of the manner the concept of evolution has been tested. This information can be used to dispel myths that have been propagated by creationists.
It is also possible to find a glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable characteristics to become more adaptable to a specific environment. This is a result of natural selection, which happens when organisms that are better-adapted characteristics are more likely to survive and reproduce than those with less adapted traits.
Common ancestor (also known as common ancestor) The most recent ancestor shared by two or more species. By analyzing DNA from these species it is possible to determine the common ancestor.
Deoxyribonucleic acid: A huge biological molecule that contains information needed for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, referred to as 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 interaction between predator and prey or the parasite and the host.
Origins
Species (groups of individuals that can interbreed) evolve through an array of natural changes in the characteristics of their offspring. These changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of a new species could take thousands of years, and the process could be slowed down or accelerated by environmental factors like climate change or the competition for food or habitat.
The Evolution site tracks the development of a number of different animal and plant groups through time with a focus on the key transitions that occurred in the history of each group. It also focuses on the evolutionary origin of humans, a topic that is particularly important for students to comprehend.
Darwin's Origin was published in 1859, at a time when only a few antediluvian fossils of humans had been found. Among them was the famous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, which was a year after the publication of the first edition of The Origin. Origin.
While the site is focused on biology, it also offers a lot of information about geology as well as paleontology. One of the most appealing features on the site are a set of timelines that illustrate how geological and climatic conditions have changed over time, as well as a map of the geographical distribution of some fossil groups that are featured on the site.
Although the site is a companion piece to the PBS television show but it also stands on its own as a valuable resource for teachers and students. The site is well-organized and provides easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized features of the museum website. These hyperlinks make it easy to move 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 research with Guppies, which demonstrate the importance of ecology in evolutionary theory.
에볼루션 바카라 무료 of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology, the study of these creatures within their natural environment offers many advantages over modern observational or research methods for studying evolutionary processes. Paleobiology focuses on not only processes and events that take place regularly or over time, but also the distribution and frequency of different species of animals in space throughout the geological time.
The site is divided into several optional paths to learning evolution that include "Evolution 101," which takes the viewer on a line through the nature of science and the evidence to support the theory of evolution. The path also examines myths about evolution, and the background of evolutionary thought.
Each of the main sections on the Evolution website is equally well-developed, and includes materials that can be used to support a variety of levels of curriculum and teaching methods. In addition to general textual content, the site offers an array of multimedia and interactive content like videos, animations and virtual labs. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation within the large web site.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of the coral's relationships, their interaction with other organisms and then is enlarged to show one clam that can communicate with its neighbors and react to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to a wide range of topics in evolutionary biology. The information also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis which is a key tool for understanding the evolution of change.
Evolutionary Theory
Evolution is an underlying thread that is found throughout all branches of biology. 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 outstanding example of a Web site that offers both depth and a variety of educational resources. The site features a wide range of interactive learning modules. It also features a nested "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this huge site that are more closely tied to the field of research science. An animation that introduces the concept of genetics, which links to a page about John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.
The Evolution Library on this website has a huge multimedia library of assets related with evolution. The contents are organized into curriculum-based paths that parallel the learning goals established in the standards for biology. It includes seven short videos specifically designed for use in the classroom, and can be streamed for no cost or purchased on DVD.
Evolutionary biology remains an area of study that poses many important questions to answer, such as what causes evolution and how quickly it happens. This is particularly true for human evolution, where it has been difficult to reconcile the notion that the innate physical characteristics of humans evolved from apes with religions that believe that humanity is unique among living things and has an exclusive place in the creation, with soul.
In addition there are a variety of ways that evolution can be triggered with natural selection being the most widely accepted theory. However scientists also study different kinds of evolution, such as mutation, genetic drift and sexual selection, among other things.
While many fields of scientific study are in conflict with the literal interpretations of religious texts, the concept of evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution but others haven't.
