7 Tips To Make The Most Out Of Your Evolution Site
Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, misconceptions persist about the evolution. People who have absorbed pop science nonsense often assume that biologists do not believe in evolution.

This site, which is a companion to the PBS series - provides teachers with materials that promote evolution education and avoid the kinds of myths that hinder it. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

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

It is therefore essential to define the terms used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful manner. The site is a companion to the show that premiered in 2001, but it also functions as an independent resource. The material is presented in a way that assists in navigation and orientation.

The site defines terms like common ancestor and the gradual process. These terms help to frame the nature of evolution and its relationship to other concepts in science. The site also provides an overview of how the concept of evolution has been tested and validated. This information can be used to dispel myths that have been created by the creationists.

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

Adaptation is the tendency of heritable traits to be better suited to an environment. This is a result of natural selection. Organisms that have better-adapted traits are more likely than those with less adaptable traits to survive and reproduce.

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

Deoxyribonucleic Acid: A large biological molecular that contains the necessary information for cell replication. The information is contained in a sequence of nucleotides that are strung together into long chains, called chromosomes. Mutations are the basis for new genetic information within cells.

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

Origins

Species (groups of individuals who can interbreed) evolve through natural changes in the traits of their offspring. These changes are caused by a variety of causes, including natural selection, genetic drift and mixing of genes. The development of a new species may take thousands of years and the process could be slowed down or speeded up by environmental factors like climate change or competition for food or habitat.

The Evolution site tracks the evolution of a variety of animal and plant groups through time, focusing on the major transitions that occurred in the history of each group. It also focuses on human evolution as a subject that is of particular interest to students.

Darwin's Origin was written in 1859, at a time when only a handful of antediluvian fossils of humans had been found. The skullcap that is famous, along with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was published in 1858, one year following the initial edition of The Origin.

The site is primarily a biology site however, it also has many details on geology and paleontology. One of the most appealing features on the site are a series of timelines that illustrate how climatic and geological conditions have changed over time, as well as an outline of the geographical distribution of some fossil groups that are featured on the site.


While the site is a companion to the 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 provides clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular there are links to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures within their geological context is a superior method of study over the current observational or experimental methods for studying evolutionary phenomena. In addition to examining processes and events that take place regularly or over a lengthy period of time, paleobiology can be used to examine the relative abundance of various kinds of organisms as well as their distribution across the geological time.

The website is divided into several paths that can be chosen to gain knowledge about evolution. One of these paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The path also examines myths regarding evolution, and also the history of evolutionary thought.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that support a variety educational levels and teaching styles. In addition to the general textual content, the site also has an extensive selection of multimedia and interactive content, such as videos, animations and virtual labs. The breadcrumb-like organization of the content helps with navigation and orientation on the large web site.

For instance the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interaction with other organisms, then concentrates on a specific clam that is able to communicate with its neighbors and react to changes in water conditions at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a broad spectrum of topics in evolutionary biology. The information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is an important tool in understanding evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that connects all branches of biology. A wide selection of resources helps teachers teach evolution across all life science disciplines.

One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that offers both the depth and breadth of its educational resources. The site offers a range of interactive learning modules. It also features an embedded "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site closer to the world of research science. For instance an animation that explains the idea of genetic inheritance connects to a page that highlights John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

Another useful resource is the Evolution Library on this website, which includes an extensive library of multimedia items that are related to evolution. The content is organized according to curricula-based pathways that correspond to the learning goals established in the biology standards. It includes seven short videos designed for use in classrooms. 에볼루션 바카라 무료 can be viewed online or purchased as DVDs.

A variety of crucial questions remain at the core of evolutionary biology, such as the factors that trigger evolution and how fast it occurs. This is particularly true for the evolution of humans where it was a challenge to reconcile religious beliefs that humanity has a special place in the creation and a soul, with the idea that innate physical traits evolved from apes.

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

While many fields of scientific inquiry have a conflict with literal interpretations of religious texts Evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
