Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions regarding evolution. People who have been exposed to popular science myths often assume that biologists claim they don't believe in evolution.

This site, which is a companion to the PBS series offers teachers with resources which support evolution education and avoid the kinds of misinformation that can hinder it. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

Evolution is a complex and difficult subject matter to teach effectively. Non-scientists often misunderstand the subject and some scientists use a definition that confuses it. This is particularly true when discussing the meaning of the words themselves.

Therefore, it is important to define terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful manner. The site serves as a companion for the 2001 series, but also a resource on its own. The material is presented in a structured way that makes it easy to navigate and comprehend.

The site defines terms like common ancestor, gradual process and so on. These terms help frame the nature and relationship of evolution with other scientific concepts. The site also provides an overview of how the concept of evolution has been tested and confirmed. This information can help dispel the myths that are created by the creationists.

You can also consult a glossary that contains terms that are used in evolutionary biology. These terms include:

The process of adaptation is the tendency of heritable traits to be more suited to the environment. This is a result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adapted traits to survive and reproduce.

Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified by analyzing the DNA of the species.

Deoxyribonucleic Acid: 에볼루션카지노 A massive biological molecular that holds the necessary information for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is a relationship between two species where evolutionary changes of one species are influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or parasite and host.

Origins

Species (groups of individuals who can interbreed) evolve through natural changes in the characteristics of their offspring. The changes can be caused by a variety of factors such as natural selection, genetic drift and mixing of genes. The evolution of new species could take thousands of years. Environmental conditions, such as changes in the climate or competition for food or habitat can impede or accelerate the process.

The Evolution site follows the evolution of different groups of animals and plants, focusing on major transitions within each group's past. It also focuses on human evolution as a subject that is of particular interest for students.

Darwin's Origin was published in 1859, at a time when only a handful of antediluvian fossils of humans were 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 regarded as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just a year before the first edition of the Origin was published, it is highly unlikely that Darwin had heard or seen of it.

The site is mostly one of biology however it also includes many details on geology and paleontology. The Web site has several aspects that are quite impressive, including the timeline of how geological and climate conditions have changed over time. It also has maps that show the locations of fossil groups.

The site is a companion for the PBS TV series but it can also be used as an educational source for teachers and students. The site is well-organized and provides clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's support) and the more specific features of the museum website. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly, there are links 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 in their natural environment and has many advantages over the modern observational and research methods of examining evolutionary phenomena. Paleobiology is able to study not just the processes and events that take place regularly or over time, but also the distribution and frequency of different groups of animals in space throughout the geological time.

The website is divided into various paths that can be chosen to study the subject of evolution. One of these paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The course also focuses on misconceptions regarding evolution, and also the history of evolutionary thought.

Each of the main sections on the Evolution website is equally well-designed, with materials that can be used to support a variety of educational levels and teaching styles. The site includes a variety of interactive and multimedia content, including video clips, animations and virtual labs in addition to general textual content. The content is organized in a nested, bread crumb fashion that aids navigation and orientation within the large web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides an overview of coral relationships, their interaction with other organisms and is enlarged to show one clam that can communicate with its neighbours and respond to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, gives a good introduction to many topics in evolutionary biology. The content also includes an explanation of the importance of natural selection and the concept of phylogenetics as a key tool to understand 에볼루션게이밍 evolutionary changes.

Evolutionary Theory

For biology students evolution is a crucial thread that weaves together all branches of the field. A rich collection supports teaching evolution across all disciplines of life science.

One resource, a companion to the PBS television series Understanding Evolution, 무료 에볼루션 is an outstanding example of an Web site that offers both depth and breadth in its educational resources. The site features a wide range of interactive learning modules. It also has a "bread crumb structure" that helps students move away from the cartoon style of Understanding Evolution and onto elements on this large website more closely linked to the realms of research science. For example an animation that introduces the idea of genetic inheritance connects to a page that highlights John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.

Another resource that is worth mentioning is the Evolution Library on this Web site, which contains an extensive collection of multimedia resources related to evolution. The content is organized into curricula-based pathways that correspond to the learning objectives outlined in the biology standards. It includes seven short videos designed specifically for use in classrooms, and can be streamed for free or purchased on DVD.

A number of important questions remain in the midst of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is particularly true in the case of human evolution, where it was difficult to reconcile religious beliefs that humanity has a unique place in creation and a soul, 에볼루션 게이밍 with the idea that innate physical traits evolved from the apes.

There are a myriad of other ways in which evolution can take place including natural selection, which is the most well-known theory. Scientists also study other types like mutation, genetic drift and sexual selection.

Many fields of inquiry are in conflict with literal interpretations of the Bible Evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, while others haven't.
