Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution remain. Pop science fiction has led a lot of people to think that biologists don't believe in evolution.

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

Definitions

It's difficult to effectively teach evolution. People who are not scientists often have a difficult time understanding the subject, and some scientists even use a definition which confuses it. This is particularly true when discussing the meaning of the words themselves.

It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site is a companion to the show which first aired in 2001, but it is also an independent resource. The content is presented in an organized manner that makes it easier to navigate and understand.

The site defines terms such as common ancestor and the gradual process. These terms help to define the nature of evolution and its relation to other concepts in science. The website provides a summary of the manner the concept of evolution has been examined. This information can be used to dispel myths that have been engendered by creationists.

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

Adaptation: The tendency for 에볼루션 바카라 무료체험 (https://telegra.Ph/20-resources-that-will-make-You-better-at-evolution-baccarat-12-24-3) heritable characteristics to become more suitable to a particular setting. This is the result of natural selection. Organisms with more adaptable characteristics are more likely than those with less-adapted characteristics to survive and reproduce.

Common ancestor: The latest common ancestor of two or more species. The common ancestor can be identified by analyzing the DNA of these species.

Deoxyribonucleic acid: A huge biological molecule that contains information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are responsible for 에볼루션카지노사이트 the creation of new genetic information within cells.

Coevolution is the relationship between two species, where the evolution of one species are influenced by evolutionary changes of the other. Coevolution can be observed in the interactions between predator and prey, or parasites and hosts.

Origins

Species (groups of individuals that can interbreed) evolve through an array of natural changes in the traits of their offspring. Changes can be caused by numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, such as climate change or competition for food resources and habitat can slow or speed up the process.

The Evolution site traces the emergence of a variety of species of plants and animals over time and focuses on the most significant transitions that occurred in the history of each group. It also explores human evolution and is a subject of particular importance for students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils 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 to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, one year after the first edition of the Origin was published, it's extremely unlikely that Darwin had heard or seen of it.

While the site focuses on biology, it also contains a wealth of information about geology and paleontology. One of the most appealing features on the site are a series of timelines which show how climatic and geological conditions changed over time, as well as a map of the distribution of a few fossil groups that are featured on the site.

The site is a companion for the PBS television series, but it could also be used as a resource by 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 funding) and the more specific features on the museum's website. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. Particularly, there are links to John Endler's research with Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of plants, animals and insects. Paleobiology is the study of these creatures in their geological context and has a number of advantages over the current observational and experimental methods in its exploration of evolutionary processes. 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 various groups of organisms and their distribution throughout the geological time.

The site is divided into various options to study the subject of evolution. One of the paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The path also reveals common misconceptions about evolution and the evolution of thought.

Each of the main sections of the Evolution website is equally well-designed, 에볼루션코리아 with materials that support a variety curriculum levels and teaching styles. The site includes a variety of multimedia and interactive resources that include animations, video clips and virtual labs in addition to general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the large Web site.

For example the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interaction with other organisms. Then, it zooms in on a single clam that is able to communicate with its neighbours and respond to changes in water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages, offers a great introduction to a variety of topics in evolutionary biology. The content also includes an explanation of the role of natural selection and the concept of phylogenetic analysis, which is a key method to understand evolutionary change.

Evolutionary Theory

For biology students evolution is a crucial thread that weaves together all branches of the field. A wide range of resources helps teachers teach about evolution across the life sciences.

One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both the depth and the broadness in terms of educational resources. The site offers a variety of interactive learning modules. It also features a nested "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 introducing the concept of genetic inheritance links to a page that focuses on John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.

Another helpful resource is the Evolution Library on this site, which contains an extensive library of multimedia items that are related to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives set out in the biology standards. It contains seven videos specifically designed for use in classrooms, and can be streamed for free or purchased on DVD.

A number of important questions remain at the core of evolutionary biology, including what causes evolution to occur and the speed at which it occurs. This is particularly true for the evolution of humans, where it was difficult to reconcile religious beliefs that held that humanity has a unique place in the creation and a soul with the notion that human beings have innate physical traits evolved from the apes.

There are also a number of other ways in which evolution could occur, with natural selection as the most popular theory. Scientists also study other types like mutation, genetic drift and sexual selection.

While many scientific fields of inquiry have a conflict with literal interpretations of religious texts, evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, other religions have not.
