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 believe that biologists don't believe evolution.

This site, which is a companion to the PBS series offers teachers with resources that support evolution education and avoid the kinds of misinformation that can hinder it. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It's difficult to properly teach evolution. It is often misunderstood even by non-scientists, and even scientists use a definition that confuses the issue. This is especially relevant when it comes to the nature of the words themselves.

It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site is a companion to the show that premiered in 2001, but it can also function as an independent resource. The material is presented in a nested fashion that assists in navigation and orientation.

The site defines terms such as common ancestor (or common ancestor), gradual process, and adaptation. These terms help frame 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 validated. This information will help to dispel the myths that are created by the creationists.

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

Adaptation: The tendency for hereditary traits to become more suitable to a particular setting. This is a result of natural selection. Organisms with better-adapted traits are more likely than those with less-adapted traits to survive and reproduce.

Common ancestor (also known as common ancestor) is the most recent ancestral ancestor shared by two or more species. By analyzing DNA from these species it is possible to determine the common ancestor.

Deoxyribonucleic acid: A massive biological molecule that contains information necessary for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the source of new genetic information in cells.

Coevolution is a relationship between two species, where the evolution of one species influence evolutionary changes of the other. Coevolution is evident in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups that can interbreed), evolve through a series natural changes in the traits of their offspring. The changes can be caused by a variety of factors such as natural selection, genetic drift, and gene pool mixing. The evolution of new species could take thousands of years. Environmental circumstances, such as changes in the climate or competition for food or habitat can slow or speed up the process.

The Evolution site follows the evolution of different animal and plant groups, focusing on major transitions within each group's past. It also examines the evolution of humans and is a subject that is of particular interest to students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The famous skullcap, along with the bones associated with it were 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, which was a year before 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 includes a good deal of information on geology and paleontology. The website has numerous features that are especially impressive, such as an overview of the way that climate and geological conditions have changed over time. It also has an interactive map that shows the location of fossil groups.

The site is a companion for a PBS television series, but it could be used as a source for teachers and students. The site is very well organized and provides clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and 에볼루션코리아; Posteezy.com, the more specialized components 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 realms of research science. There are links to John Endler's experiments with guppies. They demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of plants, animals and insects. Paleobiology is the study of these creatures in their natural environment and has many advantages over modern observational and experimental methods in its exploration of evolutionary processes. Paleobiology is able to study not only processes and events that happen frequently or over time, but also the distribution and frequency of different groups of animals across geological time.

The website is divided into different routes that can be taken to study the subject of evolution. One of the paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The course also focuses on misconceptions about evolution, and the background of evolutionary thought.

Each of the main sections of the Evolution website is equally well-developed, 에볼루션코리아 and includes 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 에볼루션코리아 multimedia resources, such as videos, animations and virtual labs. The content is presented in a nested bread crumb-like fashion that helps with navigation and orientation within the large web site.

The page "Coral Reef Connections" For instance, it provides an overview of the coral's relationships and their interactions with other organisms, and then zooms in to one clam, which is able to communicate with its neighbours and respond to changes in the conditions of the water that occur at the reef level. This page, 에볼루션바카라사이트 along with the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to the many areas of evolutionary biology. The information also includes an explanation of the role of natural selection and the concept of phylogenetic analysis, which is a key method to understand evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A rich collection of resources helps teachers teach about evolution across all life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both depth and breadth in its educational resources. The site has a variety of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this huge site that are more closely linked to the world of research science. For example, an animation introducing the idea of genetic inheritance connects to a page highlighting John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated to evolution. The content is organized according to courses that are based on curriculum and follow the learning goals established in the biology standards. It contains seven videos that are designed for classroom use. These can be viewed online or purchased as DVDs.

A variety of crucial questions remain in the midst of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is especially true in the case of human evolution which was a challenge to reconcile religious beliefs that humanity has a special position in the universe and a soul, with the notion that human beings have innate physical traits originated from the apes.

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

While many scientific fields of inquiry have a conflict with the literal interpretations of religious texts Evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, others have not.
