Evolution Site - Teaching About Evolution
Despite the best efforts by biology teachers, there are still misconceptions about the evolution. Pop science nonsense has led many people to believe that biologists don't believe evolution.
This rich Web site, which is a complement to the PBS program, provides teachers with materials that support the evolution of education, while avoiding the kinds of misconceptions which hinder it. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
It's difficult to teach evolution well. People who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. This is particularly relevant to debates about the nature of the word.
It is therefore crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The site serves as a companion for the 2001 series, and it is also a resource on its own. The content is presented in a structured manner that makes it simpler to navigate and comprehend.
The site defines terms such as common ancestor and gradual process. These terms help to define the nature of evolution and its relationship to evolution with other scientific concepts. The site provides an overview of the way that evolution has been tested. This information can be used to dispel myths that have been engendered by the creationists.
It is also possible to find the glossary of terms used in evolutionary biology. These terms include:
The process of adaptation is the tendency of hereditary traits to become better suited to an environment. This is the result of natural selection. 에볼루션 무료체험 with more adaptable characteristics are more likely than those with less adaptable characteristics to survive and reproduce.
Common ancestor: The latest common ancestor of two or more distinct species. The common ancestor can be identified through analyzing the DNA of those species.
Deoxyribonucleic acid: A large biological molecule that contains information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.
Coevolution is a relationship between two species where evolutionary changes of one species are influenced by evolutionary changes of the other. Coevolution can be seen in the interactions between predator and prey, or parasites and hosts.
Origins
Species (groups of individuals who can interbreed) evolve through natural changes in the characteristics of their offspring. These changes are caused by a variety of causes such as natural selection, genetic drift, and gene pool mixing. The development of a new species can take thousands of years, and the process may be slowed or increased by environmental factors like climate change or competition for food or habitat.
The Evolution site follows the evolution of various animal and plant groups with a focus on major changes in each group's past. It also explores human evolution and is a subject of particular importance to students.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, which was a year following the initial edition of The Origin. Origin.
While the site is focused on biology, it also offers a lot of information about geology and paleontology. One of the most appealing features on the site are a set of timelines that illustrate how climatic and geological conditions have changed over time, as well as a map of the distribution of some of the fossil groups featured on the site.
While the site is a companion to the PBS television series but it also stands on its own as a valuable resource for teachers and students. The site is well-organized, and provides clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features on the museum's website. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular there are links to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and has numerous advantages over the modern observational and research methods of examining evolutionary phenomena. In addition to exploring processes and events that take place frequently or over a long period of time, paleobiology is able to examine the relative abundance of various kinds of organisms as well as their distribution throughout geological time.
The website is divided into various paths that can be chosen to gain knowledge about evolution. One of these paths, "Evolution 101," guides the user through the nature and evidence of evolution. The course also focuses on misconceptions about evolution, and the background of evolutionary thought.
Each of the other main sections of the Evolution site is similarly developed, with materials that can be used to support a range of curriculum levels and pedagogical styles. In addition to the general textual content, the site also has an array of multimedia and interactive content like videos, animations, and virtual laboratories. The breadcrumb-like arrangement of the content helps with navigation and orientation on the massive website.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms and then is enlarged to show one clam, which is able to communicate with its neighbors and respond to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and multimedia pages offers a great introduction to the many areas of evolutionary biology. The material includes an overview of the significance of natural selectivity and the concept of phylogenetics analysis as a key method for understanding the evolution of change.
Evolutionary Theory
Evolution is an underlying thread that is found throughout all branches of biology. A rich collection supports teaching evolution across the life science disciplines.
One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that provides the depth and breadth of its educational resources. The site offers a variety of interactive learning modules. It also features an "bread crumb structure" that assists students in moving away from the cartoon-like style of Understanding Evolution and onto elements on this large website more closely related to the fields of research science. For instance an animation that explains the idea of genetic inheritance connects to a page highlighting John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.
Another useful resource is the Evolution Library on this site, which has an extensive collection of multimedia items related to evolution. The content is organized into courses that are based on curriculum and follow the learning objectives outlined in the biology standards. It contains seven short videos that are designed for use in classrooms. These are available to stream or purchase as DVDs.
Evolutionary biology is still an area of study that poses many important questions, such as what causes evolution and the speed at which it takes place. This is particularly true for human evolution, which has made it difficult to reconcile the idea that the innate physical characteristics of humans derived from apes and religious beliefs that claim that humanity is unique among living things and holds a an enviable place in creation. It is soul.
In addition there are a myriad of ways that evolution can be triggered, with natural selection being the most popular theory. Scientists also study different types such as genetic drift, and sexual selection.
Although many scientific fields of study are in conflict with literal interpretations in religious texts, evolution biology has been a subject of intense debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, others aren't.
