Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions about evolution. Pop science nonsense has led people to believe that biologists don't believe evolution.

This rich website - companion to the PBS series offers teachers with resources that promote evolution education and help avoid the kinds of misconceptions that undermine it. It's organized in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to properly teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition that confuses it. This is particularly relevant when discussing the meaning of the words themselves.

It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient manner. The site is both an accompaniment to the 2001 series, but it is also a resource on its own. The content is presented in a nested fashion that assists in navigation and orientation.

The site defines terms like common ancestor, gradual process and so on. These terms help frame the nature and significance of evolution to other scientific concepts. The website provides a summary of the way that evolution has been tested. This information can be used to dispel myths that have been propagated by the creationists.

It is also possible to find a glossary of terms that are used in evolutionary biology. These terms include:

The process of adaptation is the tendency of heritable traits to become more suitable to their environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted traits to reproduce and survive.

Common ancestor: The latest common ancestor of two or more different species. By studying the DNA of these species it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A large biological molecular containing the information needed for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, also known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey or the parasite and the host.

Origins

Species (groups which can interbreed) develop through a series natural changes in their offspring's traits. Changes can be caused by various factors, including natural selection, gene drift, and mixing of the gene pool. The evolution of a new species can take thousands of years, and the process can be slowed down or speeded up by environmental factors like climate change or the competition for 에볼루션 게이밍 에볼루션 바카라 체험사이트 [sources] food or habitat.

The Evolution site traces the emergence of various species of plants and animals over time and focuses on the most significant transitions that occurred in each group's history. It also focuses on the human evolutionary roots which is especially important for students to understand.

Darwin's Origin was published in 1859, when just a handful of antediluvian fossils of human beings had been discovered. Among them was the famous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap when it was published in 1858, a year after the publication of the first edition of The Origin. Origin.

The site is primarily a biology site, but it also contains lots of information about paleontology and geology. One of the most appealing features of the website are a series of timelines that show the way in which climatic and geological conditions have changed over time as well as an interactive map of the geographical distribution of some fossil groups that are featured on the site.

Although the site is a companion piece to a PBS television series however, it can stand on its own as a valuable source for teachers and students. The site is well-organized and offers easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features of the museum's website. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular there are links to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in many species of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment and has numerous advantages over the current observational and experimental methods in its exploration of evolutionary phenomena. In addition to studying processes and events that occur regularly or over a long period of time, paleobiology can be used to study the relative abundance of different groups of organisms and their distribution across 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 nature and evidence of evolution. The path also reveals common misconceptions about evolution and the evolution theory's history.

Each of the other major sections of the Evolution site is equally well developed, with materials that can support a variety of curriculum levels and pedagogical styles. In addition to general textual content, the site offers an array of multimedia and interactive resources including videos, animations, and virtual laboratories. The breadcrumb-like organization of the content assists with navigation and orientation on the large website.

For instance, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms. It then concentrates on a specific clam that is able to communicate with its neighbors and react to changes in the water conditions at the level of the reef. This page, along with the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a wide variety of topics in evolutionary biology. The content includes a discussion on the role of natural selectivity and the concept phylogenetics analysis which is a crucial method for understanding the evolution of changes.

Evolutionary Theory

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

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that provides depth and broadness in terms of educational resources. The site features a wealth of interactive learning modules. It also features an encased "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. For instance, an animation introducing the concept of genetic inheritance links to a page that focuses on John Endler's experiments in artificial selection with guppies in native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of assets related to evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives outlined in the standards for biology. It contains seven videos designed specifically for use in the classroom, and can be streamed for free or 에볼루션 바카라 체험 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 occurs. This is particularly true for humans' evolution, where it was difficult to reconcile religious beliefs that humanity has a special place in creation and a soul, with the notion that our physical traits were derived from Apes.

There are a variety of other ways evolution can occur including natural selection, which is the most popular theory. However scientists also study different kinds of evolution like genetic drift, mutation, and sexual selection, among others.

Although many scientific fields of study have a conflict with the literal interpretations of religious texts, the concept of evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, other religions have not.
