Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, misconceptions persist regarding evolution. Pop science fiction has led a lot of people to believe that biologists aren't believers in evolution.
This rich Web site - companion to the PBS series offers teachers with resources which support evolution education and avoid the kinds of myths that make it difficult to understand. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
Evolution is a complex and difficult subject to teach effectively. It is often misunderstood by non-scientists and even scientists have been guilty of using an interpretation that is confusing the issue. This is particularly true when discussing the meaning of the words themselves.
It is therefore crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful manner. The site is a companion site to the series that first aired in 2001, but also functions as an independent resource. The information is presented in a structured manner that makes it easier to navigate and understand.
The site defines terms such as common ancestor, gradual process, and adaptation. These terms help frame the nature of evolution and its relation to other scientific concepts. The site provides an overview of the ways the concept of evolution has been examined. This information will help to dispel the myths created by creationists.
You can also consult a glossary that contains terms that are used in evolutionary biology. These terms include:
Adaptation is the process of changing heritable traits to be better suited to an environment. This is the result of natural selection, which occurs when organisms that have better adapted traits are more likely to survive and reproduce than those with less adaptable characteristics.
Common ancestor (also called common ancestor) The most recent ancestor that is shared by two or more species. By studying the DNA of these species, it is possible to determine the common ancestor.
Deoxyribonucleic Acid: A massive biological molecular containing the necessary information for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be seen in the interactions between predator and prey, or parasite and hosts.
Origins
Species (groups that can crossbreed) develop through a series of natural changes in the traits of their offspring. The changes can be caused by a variety of causes, including natural selection, genetic drift, and gene pool mixing. The evolution of a new species can take thousands of years and the process can be slowed down or speeded up by environmental conditions such as climate change or the competition for food or habitat.
The Evolution site tracks through time the emergence of various animal and plant groups and focuses on major changes in each group's history. It also explores human evolution, which is a topic of particular importance for students.
Darwin's Origin was written in 1859, at a time when only a handful of antediluvian fossils of humans were discovered. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly 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 focuses on biology, it also includes a good deal of information about geology as well as paleontology. The most impressive features of the Web site are a timeline of events which show how climatic and geological conditions have changed over time and an outline of the distribution of some of the fossil groups featured on the site.
The site is a companion for a PBS TV series but it could also be used as a resource by teachers and students. The site is very well-organized and has clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These links facilitate the transition from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are 에볼루션 카지노 to John Endler's experiments using Guppies, which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a variety of plants, animals, and insects. Paleobiology is the study of these creatures within their geological context and has many advantages over the current observational and experimental methods of examining evolutionary phenomena. In addition to studying processes and events that take place regularly or over a lengthy period of time, paleobiology allows to study the diversity of kinds of organisms as well as their distribution throughout the geological time.
The website is divided into a variety of paths to learning evolution which include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence supporting the theory of evolution. The path also explores the most common misconceptions about evolution, as well as the evolution of thought.
Each of the main sections of the Evolution website is equally well-developed, with materials that support a variety levels of curriculum and teaching methods. In addition to the general textual content, the site features an extensive selection of multimedia and interactive content including video clips, animations, and virtual laboratories. The breadcrumb-like arrangement of the content helps with navigation and orientation on the vast web site.
For instance, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interaction with other organisms. Then, it narrows down to a single clam that can communicate with its neighbors and react to changes in the water conditions at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a broad range of topics in evolutionary biology. The information also includes an overview of the importance of natural selection and the concept of phylogenetic analysis, which is a key tool in understanding evolutionary changes.
Evolutionary Theory
For biology students the concept of evolution is a major thread that connects all the branches of the field. A vast collection of books helps in teaching evolution across the disciplines of life science.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth and broadness in terms of educational resources. The site offers a range of interactive learning modules. It also has an embedded "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the world of research science. For instance an animation that introduces the idea of genetic inheritance connects to a page highlighting John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.
Another useful resource is the Evolution Library on this site, which contains an extensive multimedia library of assets that are related to evolution. The content is organized into curricula-based paths that correspond to the learning goals set forth in the biology standards. It contains seven short videos specifically designed for classroom use. They can be viewed online or purchased as DVDs.
A variety of crucial questions remain at the heart of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is especially relevant to human evolution, where it has been difficult to reconcile the notion that the innate physical characteristics of humans were derived from apes and religious beliefs that hold that humans are unique among living things and has an exclusive place in the creation, with soul.
In addition there are a myriad of ways in which evolution could occur and natural selection is the most widely accepted theory. Scientists also study different types such as genetic drift and sexual selection.
에볼루션코리아 of inquiry are in conflict with literal interpretations of the Bible evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, others have not.
