The Little-Known Benefits Evolution Site
Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions regarding evolution. People who have absorbed pop science nonsense often assume that biologists are saying they don't believe in evolution.

This rich Web site, a companion to the PBS program offers teachers resources which support evolution education, while avoiding the kinds of misconceptions that can undermine it. It's organized in the "bread crumb" format to make navigation and orientation easier.

Definitions

It's not easy to teach evolution well. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is especially true when discussing the meaning of the words themselves.

As such, it is essential to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. It is a companion for the 2001 series, but also a resource on its own. The content is presented in a way that assists in navigation and orientation.

The site defines terms such as common ancestor and gradual process. These terms help to define the nature of evolution and its relationship to other scientific concepts. The site then offers an overview of how the concept of evolution has been tested and verified. This information will help to dispel the myths created by creationists.

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


Adaptation: The tendency of hereditary traits to become more suitable to a particular setting. This is due to natural selection, which happens when organisms that are more adaptable traits are more likely survive and reproduce than those with less adaptable traits.

Common ancestor: The most recent common ancestor of two or more different species. By analyzing DNA from these species, it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A large biological molecular that holds the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

Coevolution: A relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be observed through the interaction between predator and prey, or parasites and hosts.

Origins

Species (groups which can interbreed) change by a series of natural variations in their offspring's traits. These changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental circumstances, such as climate changes or competition for food resources and habitat can slow or speed up the process.

The Evolution site follows the evolution of various groups of animals and plants, focusing on major transitions in each group's history. It also examines the evolution of humans and is a subject that is of particular interest for students.

Darwin's Origin was written in 1859, at a time when only a handful of antediluvian fossils of humans were discovered. The famous skullcap, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was a year before 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 offers a lot of information about geology as well as paleontology. Among the best features on the site are a timeline of events that show how geological and climatic conditions have changed over time, and an interactive map of the distribution of some fossil groups listed on the site.

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 well-organized, and provides clear links to the introduction content of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized features of the museum website. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are hyperlinks to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology is the study of these creatures within their natural environment, has many advantages over modern observational or experimental methods for exploring evolutionary phenomena. In addition to examining the processes and events that happen regularly or over a long period of time, paleobiology allows to examine the relative abundance of different groups of organisms and their distribution across 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 evolution of nature and the evidence of evolution. The course also focuses on common misconceptions about evolution as well as the evolution theory's history.

Each of the main sections of the Evolution website is equally well-designed, with materials that are suited to a variety of educational levels and teaching styles. The site includes a variety of interactive and multimedia resources that include videos, animations, and virtual laboratories in addition to general textual content. The content is organized in a nested, bread crumb style that facilitates navigation and orientation within the vast Web site.

For instance the page "Coral Reef Connections" provides an overview of coral relationships and their interaction with other organisms. It then zooms in on a single clam that can communicate with its neighbors and react to changes in the water conditions that take place at the level of the reef. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good 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

Evolution is a common thread that connects all branches of biology. A vast collection of books helps in teaching evolution across all disciplines of life science.

One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that offers both depth and a variety of educational resources. The site offers a range of interactive learning modules. It also features a nested "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely linked to the field of research science. An animation that introduces the concept of genetics is linked to a page about John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.

The Evolution Library on this website contains a large multimedia library of materials that deal to evolution. 에볼루션카지노 is organized according to curriculum-based pathways that correspond to the learning objectives set out in the standards for biology. It includes seven short videos designed for classroom use. These can be viewed online or purchased as DVDs.

Many important questions remain in the midst of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is especially relevant to human evolution, which has made it 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 among living things and holds a an enviable place in creation. It is soul.

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

While many scientific fields of inquiry have a conflict with literal interpretations of the Bible evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
