Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions persist about the evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.
This site, which is a companion to the PBS series - provides teachers with materials that support evolution education and avoid the kinds of myths that undermine it. It's laid out in a "bread crumb" format to make navigation and orientation easier.
Definitions
It's difficult to properly teach evolution. It is often misunderstood by non-scientists and even some scientists have been guilty of using a definition that confuses the issue. This is especially relevant when discussing the nature of the words themselves.
It is important to define terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a simple and efficient way. The site is a companion site to the show that premiered in 2001, but it can also function as an independent resource. The material is presented in a nested fashion which aids navigation and orientation.
The site defines terms like common ancestor and the gradual process. These terms help to define the nature of evolution as well as its relation to other scientific concepts. The website provides a summary of the manner that evolution has been examined. This information can help dispel the myths that are created by the creationists.
You can also access a glossary which contains terms that are 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. Organisms with more adaptable traits are more likely than those with less adapted characteristics to survive and reproduce.
Common ancestor (also known as common ancestor) is the most recent ancestral ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of these species.
Deoxyribonucleic acid: A huge biological molecule that contains information necessary for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, also known 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 affected by changes in evolutionary processes in the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts.
Origins
Species (groups that can interbreed) change by a series of natural variations in their offspring's traits. The changes can be caused by a variety, including natural selection, genetic drift, and mixing of genes. The evolution of new species can take thousands of years. Environmental conditions, such as climate change or competition for food or habitat can impede or accelerate the process.
The Evolution site tracks through time the evolution of various species of plants and animals, focusing on major transitions within each group's past. It also focuses on the human evolutionary roots and humans, a subject that is especially important for students to comprehend.
Darwin's Origin was written in 1859, when just a few antediluvian fossils of human beings had been discovered. The most famous among them was the skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany which is now believed as 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 first edition of The Origin.
The site is primarily a biology site however it also includes many details on paleontology and geology. Among the best features of the Web site are a timeline of events that illustrate how climatic and geological conditions 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 great source for teachers and students. The site is well organized and provides clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler’s experiments with guppies,

Diversity
The evolution of life on Earth has resulted in a variety of plants, animals, and insects. Paleobiology, the study of these creatures within their geological context is a superior method of study over the current observational or experimental methods of studying evolutionary phenomena. In addition to examining the processes and events that happen regularly or over a lengthy period of time, paleobiology allows to examine the relative abundance of different kinds of organisms as well as their distribution throughout the geological time.
The website is divided into various paths that can be chosen to learn about evolution. One of these paths, "Evolution 101," walks the reader through the evolution of nature and the evidence of evolution. The path also explores the most common misconceptions about evolution, as well as the evolution of thought.
Each of the main sections on the Evolution website is equally well-developed, with materials that can be used to support a variety of levels of curriculum and teaching methods. In addition to the standard textual content, the site features an array of interactive and multimedia resources like video clips, animations, and virtual laboratories. The content is presented in a nested bread crumb-like fashion that helps with navigation and orientation on the Web site.
For instance, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms. It then narrows down to a single clam that is able to communicate with its neighbours and respond to changes in water conditions at the level of the reef. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The content also includes an explanation of the role of natural selectivity and the concept of phylogenetics, an important tool for

Evolutionary Theory
For biology students, evolution is a key thread that weaves together all the branches of the field. A wide selection of resources helps teachers teach evolution across the disciplines of life sciences.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that provides depth and broadness in terms of educational resources. The site has a variety of interactive learning modules. It also has a nested "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the world of research science. An animation that introduces the concept of genetics, which links to a page that highlights John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.
Another useful resource is the Evolution Library on this Web website,
