Evolution Site - Teaching About Evolution
Despite the best efforts by biology teachers,
에볼루션 there are still misconceptions regarding evolution. Pop science fiction has led a lot of people to believe that biologists aren't believers in evolution.
This rich Web site, a companion to the PBS program offers teachers resources that promote evolution education while avoiding the types of misconceptions that can undermine it. It's organized in the "bread crumb" format to facilitate navigation and orientation.
Definitions
It is difficult to teach evolution well. Many non-scientists are unable to grasp the concept and some scientists use a definition which confuses it. This is especially true when discussing the definition of the words.
It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. It is an accompaniment to the 2001 series,
에볼루션 but also a resource of its own. The material is presented in a nested manner that aids navigation and orientation.
The site defines terms like common ancestor, gradual process and adaptation. These terms help to define the nature of evolution and its relation to other scientific concepts. The site then offers an overview of how the concept of evolution has been vetted and verified. This information can be used to dispel the myths that have been engendered by the creationists.
You can also access a glossary that includes terms that are used in evolutionary biology. These terms include:
Adaptation is the tendency of heritable traits to become more suitable to their environment. This is a result of natural selection, which occurs when organisms with better-adapted characteristics are more likely to survive and reproduce than those with less adaptable characteristics.
Common ancestor: The most recent common ancestor of two or
에볼루션카지노 more species. By studying the DNA of these species it is possible to identify the common ancestor.
Deoxyribonucleic acid: A large biological molecule that holds the information required for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.
Coevolution is the relationship between two species in which the evolution of one species influence evolutionary changes of the other. Examples of coevolution are the interactions between predator and prey or the parasite and
에볼루션 the host.
Origins
Species (groups of individuals who can interbreed) change through an array of natural changes in the traits of their offspring. The changes can be triggered by a variety of causes, including natural selection, genetic drift, and mixing of genes. The development of new species can take thousands of years. Environmental conditions, like climate change or competition for food and habitat can slow or speed up the process.
The Evolution site tracks the development of various animal and plant groups through time with a focus on the key shifts that occurred throughout the evolution of each group's history. It also explores human evolution as a subject that is particularly important to students.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The skullcap that is famous, along with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was one year after the first edition of the Origin was published, it's extremely unlikely that Darwin had seen or heard of it.
While the site is focused on biology, it includes a good deal of information on geology and paleontology. Among the best features of the website are a series of timelines which show how geological and climatic conditions have changed over time as well as an outline of the distribution of some of the fossil groups featured on the site.
The site is a companion to a PBS television series, but it can also be used as a source for teachers and students. The site is well-organized and offers easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features of the museum website. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are also 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 plants, animals and insects. Paleobiology is the study of these creatures in their natural environment is a superior
에볼루션 룰렛 바카라 체험 (
Unit.igaoche.com) method of study over the current observational or experimental methods of studying evolutionary processes. Paleobiology focuses on not just the processes and events that happen regularly or over time, but also the distribution and frequency of different species of animals across the geological time.
The site is divided into different routes that can be taken to learn about evolution. One of these paths, "Evolution 101," takes the viewer through the complexities and
에볼루션 게이밍 evidence of evolution. The path also explores common misconceptions about evolution and the history of evolutionary thought.
Each of the main sections of the Evolution website is equally well-developed, and includes materials that can be used to support a variety of educational levels and teaching styles. In addition to the general textual content, the site also has a wide range of multimedia and interactive resources, such as videos, animations and
에볼루션 사이트 virtual labs. The content is laid out in a nested bread crumb style that facilitates navigation and orientation within the large web site.
The page "Coral Reef Connections" For instance, it provides a comprehensive overview of the coral's relationships and their interactions with other organisms, and then zooms in to one clam that can communicate with its neighbors and respond to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, offers a great introduction to the many areas of evolutionary biology. The material includes an overview of the role of natural selectivity and the concept phylogenetics analysis, an important method for understanding the evolution of change.
Evolutionary Theory
For biology students evolution is a crucial thread that weaves together all the branches of the field. A vast 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 as well as broadness in terms of educational resources. The site features a wealth of interactive learning modules. It also features a "bread crumb structure" that helps students move away from the cartoon-like style used in Understanding Evolution and onto elements of this vast website that are closely connected to the fields of research science. For instance an animation that introduces the concept of genetic inheritance links to a page highlighting John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.
The Evolution Library on this website is a vast multimedia library of resources that are associated to evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives outlined in biology standards.
