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 aren't believers in evolution.

This rich Web site, which is a complement to the PBS program offers teachers resources which support evolution education, while avoiding the kinds of misconceptions which undermine it. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

Evolution is a complicated and challenging subject to teach effectively. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is particularly true when discussing the meaning of the words themselves.

It is therefore important to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient manner. The website is a companion to the series that first aired in 2001, but it can also function as an independent resource. The content is organized in a manner that makes it easier to navigate and understand.

The site defines terms like common ancestor, the gradual process, and adaptation. These terms help to define the nature of evolution and its relation to other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and confirmed. This information can be used to dispel misconceptions that have been engendered by creationists.

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

Adaptation: The tendency for heritable traits to become better suitable to a particular setting. This is the result of natural selection. It occurs when organisms with more adaptable characteristics are more likely to survive and reproduce than those with less adaptable traits.

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

Deoxyribonucleic Acid: A massive biological molecular that contains the information needed for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

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

Origins

Species (groups that can crossbreed) develop through a series 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 development of a new species may take thousands of years, and the process may be slowed down or accelerated by environmental conditions such as climate change or the competition for food or habitat.

The Evolution site follows the evolution of different groups of animals and plants, focusing on major 무료 에볼루션 transitions in each group's past. It also explores the evolutionary origin of humans which is particularly important for students to understand.

Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans were discovered. One of them was the infamous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, which was a year following the initial edition of The Origin.

The site is primarily a biology site, but it also contains many details on geology and paleontology. The most impressive features on the site are a timeline of events that show how climatic and geological conditions changed over time, and an interactive map of the distribution of some fossil groups listed on the site.

While the site is a companion to a PBS television show, it also stands on its own as an excellent source for teachers and students. The site is well-organized, and provides clear links to the introduction content of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features on the museum's website. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler's experiments with guppies, which illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life has led to a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over the modern observational and research methods of examining evolutionary processes. In addition to examining the processes and events that happen frequently or over a long period of time, paleobiology is able to study the relative abundance of various groups of organisms and their distribution in space over the geological time.

The site is divided into different routes that can be taken to study the subject of evolution. One of these paths, "Evolution 101," guides the user through the nature and evidence of evolution. The path also explores common misconceptions about evolution and 에볼루션 사이트 the evolution theory's history.

Each of the main sections on the Evolution website is equally well-developed, with materials that can be used to support a variety of educational levels and teaching styles. In addition to the standard textual content, the site also has a wide range of interactive and multimedia resources, such as video clips, animations, and virtual labs. The breadcrumb-like structure of the content assists with navigation and orientation on the vast Web site.

For instance, the page "Coral Reef Connections" provides an overview of coral relationships and their interaction with other organisms. Then, it narrows down to a single clam that is able to communicate with its neighbors and respond to changes in the water conditions that take place at the level of the reef. This page, along with the other multidisciplinary, 에볼루션 카지노 사이트 에볼루션 바카라 사이트 체험 (http://0Lq70ey8yz1b.com/home.Php?mod=space&uid=1019636) multimedia and interactive pages on the site, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The content includes a discussion on the significance of natural selectivity and the concept phylogenetics analysis as a key tool for understanding evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A wide range of resources helps teachers teach about evolution across the life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that provides depth and breadth in its educational resources. The site offers a range of interactive learning modules. It also has an encased "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. An animation that introduces the concept of genetics is linked to a page highlighting John Endler's experiments with artificial selection using guppies on native ponds in Trinidad.

Another resource that is worth mentioning is the Evolution Library on this web site, which contains an extensive library of multimedia assets that are related to evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives outlined in the biology standards. It contains seven videos designed specifically 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, such as the factors that trigger evolution and how fast it occurs. This is especially true for the evolution of humans, where it was difficult to reconcile religious beliefs that humans have a distinct place in creation and a soul, with the idea that innate physical traits were derived from the apes.

There are also a number of other ways evolution can occur including natural selection, which is the most well-known theory. However scientists also study other kinds of evolution, such as genetic drift, 에볼루션 mutation, 에볼루션 무료체험 and sexual selection, among others.

Many fields of inquiry conflict with the literal interpretations of religious texts evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs to evolution while others haven't.
