Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution remain. Pop science nonsense has led people to believe that biologists aren't believers in evolution.
This rich Web site, which is a companion to the PBS program offers teachers resources which support evolution education while avoiding the types of misconceptions that hinder it. It's laid out in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
Evolution is a complex and challenging subject to teach well. It is often misunderstood by non-scientists and even scientists are guilty of using a definition that confuses the issue. 에볼루션 카지노 is especially relevant when it comes to the definition of the words.
It is essential to define terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient way. The site is a companion site to the show which first aired in 2001, but it is also an independent resource. The content is presented in a nested manner that aids navigation and orientation.
The site defines terms like common ancestor and the gradual process. These terms help to frame the nature of evolution as well as its relationship to other scientific concepts. The website provides a summary of the way that evolution has been examined. This information can be used to dispel myths that have been created by creationists.
It is also possible to find a glossary of terms that are used in evolutionary biology. These terms include:
Adaptation is the tendency of hereditary traits to become more suitable to their environment. This is the result of natural selection. It occurs when organisms that are more adaptable traits are more likely to survive and reproduce than those with less adaptable characteristics.
Common ancestor: The most recent common ancestor of two or more distinct species. By analyzing the DNA from these species, it is possible to identify the common ancestor.
Deoxyribonucleic acid: A massive biological molecule that contains the information needed for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are the source of new genetic information in cells.
Coevolution: A relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or parasite and host.
Origins
Species (groups that can crossbreed) develop by a series of natural variations in the traits of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of a new species could take thousands of years and the process may be slowed down or speeded up by environmental conditions such as climate change or competition for food or habitat.
The Evolution site traces the emergence of a variety of species of plants and animals over time, focusing on the major transitions that occurred in the history of each group. It also focuses on human evolution as a subject that is of particular interest for students.
Darwin's Origin was published in 1859, when just a handful of antediluvian fossils of humans had been found. The skullcap that is famous, along with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was first published in 1858, one year following the initial edition of The Origin. Origin.
The site is mostly a biology site however, it also has many details on geology and paleontology. One of the most appealing features of the Web site are a set of timelines which show the way in which climatic and geological conditions have changed over time, and an interactive map of the distribution of some fossil groups that are featured on the site.
While the site is a companion to a PBS television show, 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 content of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features of the museum website. These hyperlinks help users move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler’s experiments with guppies, which illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology is the study of these creatures within their natural environment, has many advantages over modern observational or research methods of studying evolutionary phenomena. In addition to examining processes and events that occur regularly or over a long period of time, paleobiology can be used to analyze the relative abundance of various kinds of organisms as well as their distribution across geological time.
The site is divided up into different options to study the subject of evolution. One of the paths, "Evolution 101," walks the reader through the nature and evidence of evolution. The course also focuses on common misconceptions about evolution as well as the evolution theory's history.
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 levels of curriculum and teaching methods. The site offers a wide array of interactive and multimedia resources which include video clips, animations and virtual laboratories, in addition to its general textual content. The content is organized in a nested, bread crumb style that facilitates navigation and orientation within the large web site.
For instance, the page "Coral Reef Connections" provides an overview of coral relationships and their interaction with other organisms. It then narrows down to a single clam that can communicate with its neighbors and react to changes in water conditions at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages gives a good introduction to a variety 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 crucial method to understand evolutionary change.
Evolutionary Theory
For biology students, evolution is a key thread that connects all branches of the field. A vast collection of books helps in teaching evolution across the life science disciplines.
One resource, the companion to PBS's television series Understanding Evolution is an excellent example of a Web site that provides depth and broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also features a "bread crumb structure" that assists students in moving away from the cartoon-like style that is used in Understanding Evolution and onto elements of this vast website that are closely related to the worlds of research science. An animation that introduces students to the concept of genetics, which links to a page about John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.
Another resource that is worth mentioning is the Evolution Library on this web site, which has an extensive multimedia library of resources that are related to evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives set out in the biology standards. It includes seven short videos that are designed for classroom use. These are available to stream or purchase as DVDs.
Evolutionary biology remains an area of study that poses many important questions, such as the causes of evolution and how quickly it occurs. This is particularly true for human evolution, where it's been difficult to reconcile the notion that the physical characteristics of humans were derived from apes, and the religions that believe that humanity is unique in the universe and has a special place in creation. It is a soul.
There are also a number of other ways evolution can take place including natural selection, which is the most popular theory. However scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among others.
While many scientific fields of inquiry conflict with literal interpretations of religious texts, evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, but others haven't.
