5 Arguments Evolution Site Can Be A Beneficial Thing
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions persist about evolution. Pop science nonsense has led many people to think that biologists don't believe in evolution.
This rich Web site, a companion to the PBS program offers teachers resources which support evolution education, while avoiding the kinds of misconceptions that can undermine it. It's laid out in a "bread crumb" format to facilitate navigation and orientation.
Definitions
It's difficult to teach evolution well. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. This is particularly applicable to debates about the nature of the word.
It is essential to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The site serves as a companion for the 2001 series, but also a resource of its own. The information is presented in an organized manner that makes it simpler to navigate and understand.
The site defines terms like common ancestor, gradual process, and adaptation. These terms help frame 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 validated. This information will help to dispel the myths that are created by the creationists.
It is also possible to find a glossary of terms used in evolutionary biology. These terms include:
Adaptation is the tendency of hereditary traits to become better suited to an environment. This is the result of natural selection. It occurs when organisms with better adapted traits are more likely to survive and reproduce than those with less adaptable traits.
Common ancestor: The most recent common ancestor of two or more different species. The common ancestor can be identified through analyzing the DNA of the species.
Deoxyribonucleic acid: A huge biological molecule that contains information needed for cell replication. The information is contained in a sequence of nucleotides that are strung together into long chains, 무료에볼루션 also known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.
Coevolution is a relation between two species, where the evolutionary changes of one species influence evolutionary changes of the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts.
Origins
Species (groups of individuals who can interbreed) change through natural changes in the traits of their offspring. These changes are caused by a variety, including natural selection, genetic drift, and mixing of genes. The evolution of a new species can take thousands of years and the process may be slowed down or speeded up due to environmental conditions, such as climate change or competition for food or habitat.
The Evolution site follows the evolution of different animal and plant groups, focusing on major transitions within each group's past. It also examines the evolution of humans 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 were discovered. Among them was the famous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought as 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.
While the site focuses on biology, it also contains a wealth of information on geology and paleontology. The most impressive features of the website are a series of timelines which show how geological and climatic conditions have changed over time and an outline of the distribution of some fossil groups listed on the site.
The site is a companion to the PBS TV series but it could be used as a resource for teachers and students. The site is extremely well-organized and offers clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly, there are links to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology is the study of these creatures within their geological context and has many advantages over modern observational and experimental methods for analyzing evolutionary processes. In addition to examining the processes and events that happen frequently or over a long period of time, paleobiology is able to analyze the relative abundance of various species of organisms and their distribution across geological time.
The website is divided into several routes that can be taken to learn about evolution. One of these paths, "Evolution 101," guides the user through the evolution of nature and the evidence of evolution. The path also explores misconceptions about evolution, as well as the history of evolutionary thinking.
Each of the other major sections of the Evolution site is similarly created, with resources that support a variety of curriculum levels and pedagogical styles. The site has a range of interactive and multimedia resources, including video clips, animations and virtual labs in addition to general textual content. The content is presented in a nested bread crumb style that facilitates navigation and orientation within the large web site.
For example, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms. Then, it zooms in on a single clam that can communicate with its neighbours and respond to changes in water conditions that take place at the level of the reef. This page, along with the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to many topics in evolutionary biology. The material includes a discussion on the role of natural selectivity and 에볼루션바카라사이트 the concept phylogenetics analysis as a key method for understanding the evolution of changes.
Evolutionary Theory
Evolution is a common thread that connects all branches of biology. A wide range of resources supports teaching about evolution across the life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that provides depth and breadth in its educational resources. The site has a wide array of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this huge site that are closer to the field of research science. For example an animation that introduces the notion of genetic inheritance leads to a page that focuses on John Endler's artificial selection experiments with guppies in native ponds of Trinidad.
Another resource that is worth mentioning is the Evolution Library on this Web site, which contains an extensive multimedia library of items that are related to evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives outlined in biology standards. It contains seven videos designed specifically for classroom use, which can be streamed for no cost or purchased on DVD.
A variety of crucial questions remain at the heart of evolutionary biology, such as what causes evolution to occur and the speed at which it occurs. This is especially true for human evolution, which has made it difficult to reconcile the idea that the physical characteristics of humans derived from apes, 에볼루션 바카라 체험 (Www.condev.ru) and the religious beliefs that hold that humans are unique in the universe and has a special place in creation. It is soul.
Additionally there are a myriad of ways that evolution could be triggered and natural selection is the most popular theory. However scientists also study different kinds of evolution, such as genetic drift, mutation, and sexual selection, among others.
While many scientific fields of study conflict with literal interpretations in religious texts, the concept of evolution biology has been a source of intense controversy and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
