Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. People who have taken in popular science myths often assume that biologists are saying they do not believe in evolution.

This site, which is a companion to the PBS program, provides teachers with materials that support the evolution of education, while avoiding the kinds of misconceptions which make it difficult to understand. It's laid out in a "bread crumb" format to make navigation and 에볼루션 바카라사이트 orientation easier.

Definitions

Evolution is a complicated and challenging subject to teach effectively. It is often misunderstood by non-scientists and even scientists are guilty of using definitions that confuse the issue. This is particularly true when discussing the meaning of the words themselves.

It is important to define terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful manner. The site serves as an accompanying site for the 2001 series, and also a resource of its own. The material is presented in a way which aids navigation and orientation.

The site defines terms such as common ancestor, gradual process, and adaptation. These terms help to define the nature and relationship of evolution to other scientific concepts. The website then provides an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel myths that are created by the creationists.

You can also access a glossary which includes terms that are used in evolutionary biology. These terms include:

Adaptation: The tendency of heritable characteristics to become more suited to a particular environment. This is the result of natural selection. Organisms with better-adapted traits are more likely than those with less-adapted traits to reproduce and survive.

Common ancestor (also called common ancestor) The most recent ancestral ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of those species.

Deoxyribonucleic acid: A massive 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, also known as chromosomes. Mutations are the basis for new genetic information in cells.

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

Origins

Species (groups that can crossbreed), evolve through a series of natural changes in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, like climate change or competition for 무료 에볼루션 food or habitat can slow or speed up the process.

The Evolution site follows the emergence of various animal and plant groups with a focus on major changes in each group's history. It also focuses on human evolution, which is a topic that is of particular interest to students.

Darwin's Origin was published in 1859, at a time when only a few antediluvian fossils of human beings had been discovered. The skullcap that is famous, along with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, one year after the first edition of the Origin was published, it is highly unlikely that Darwin had heard or seen of it.

While the site is focused on biology, it also offers a lot of information about geology and paleontology. One of the most appealing features on the site are a timeline of events which show the way in which climatic and geological conditions changed over time, as well as a map of the distribution of some fossil groups that are featured on the site.

Although the site is a companion piece to a PBS television show however, it can stand on its own as a valuable source for teachers and students. The site is extremely well-organized and offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated components of the museum's Web site. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. In particular there are hyperlinks to John Endler's experiments using Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geographical context and offers many advantages over the modern observational and research 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 allows to analyze the relative abundance of different kinds of organisms as well as their distribution across geological time.

The site is divided into various options to gain knowledge about evolution. One of the paths, "Evolution 101," walks the reader through the nature and evidence of evolution. The course also focuses on misconceptions regarding evolution, and the background of evolutionary thinking.

Each of the other main sections of the Evolution site is equally constructed, with materials that can support a variety of curriculum levels and pedagogical styles. In addition to the standard textual content, the site offers an array of interactive and multimedia resources, such as videos, animations, and virtual laboratories. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the large Web site.

The page "Coral Reef Connections", for example, gives a brief overview of the relationships between corals and interactions with other organisms, 무료 에볼루션 and then zooms in to a single clam, which is able 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, 에볼루션 게이밍 multimedia, and interactive pages on the website, provide an excellent introduction to a wide range of topics in evolutionary biology. The material includes a discussion on the importance of natural selection and the concept of phylogenetics analysis as a key tool to understand 에볼루션 게이밍 evolutionary change.

Evolutionary Theory

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

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web site that provides depth as well as broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also features a "bread crumb structure" that allows students to move away from the cartoon-like style that is used in Understanding Evolution and onto elements on this large website more closely linked to the fields of research science. Animation that introduces the concept of genetics links to a page that highlights John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.

The Evolution Library on this website has a huge multimedia library of resources that are associated with evolution. The content is organized according to curriculum-based paths that parallel the learning objectives set out in the standards for biology. It contains seven videos that are intended for use in the classroom. They can be streamed or purchased as DVDs.

Evolutionary biology remains a field of study that poses many important questions, including the causes of evolution and the speed at which it happens. This is especially true for human evolution, where it's been difficult to reconcile the notion that the innate physical characteristics of humans were derived from apes with religious beliefs that claim that humanity is unique in the universe and has a special place in creation, with a soul.

There are a variety of other ways in which evolution can occur and natural selection being the most popular theory. Scientists also study different types like mutation, genetic drift, and sexual selection.

While many fields of scientific study conflict with the literal interpretations of religious texts, evolution biology has been a source of intense controversy and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, but others haven't.
