Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions persist regarding evolution. Pop science nonsense has led people to believe that biologists don't believe evolution.

This rich Web site, a companion to the PBS program offers teachers resources that promote evolution education while avoiding the types of misconceptions which undermine it. It's organized in a nested "bread crumb" format to facilitate navigation and 에볼루션 바카라 사이트 orientation.

Definitions

Evolution is a complicated and challenging subject to teach 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 especially relevant to debates about the meaning of the word itself.

As such, 에볼루션 룰렛 무료 바카라 (jszst.com.cn) it is important to define terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in a simple and efficient way. The site is a companion to the series that first aired in 2001, but can also function as an independent resource. The material is presented in a nested fashion 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 significance of evolution with other scientific concepts. The site provides an overview of the manner in which evolution has been examined. This information can be used to dispel the myths that have been engendered by the creationists.

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

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

Common ancestor (also called common ancestor): The most recent ancestral ancestor shared by two or more species. By analyzing DNA from these species it is possible to identify the common ancestor.

Deoxyribonucleic acid: A huge biological molecule that contains the information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is a relationship between two species where evolution of one species are influenced evolutionary changes in the other. Coevolution is evident through the interaction between predator and prey, 에볼루션 바카라 사이트 or parasite and hosts.

Origins

Species (groups of individuals that can interbreed) develop through natural changes in the characteristics or the National Science Foundation's assistance) and the more specialized features on the museum's website. These hyperlinks help users move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular, there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has resulted in a variety of animals, plants and insects. Paleobiology, the study of these creatures in their geological environment is a superior method of study over modern observational or research 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 groups of organisms and their distribution throughout the geological time.

The site is divided into a variety of paths to learning evolution, including "Evolution 101," which takes the viewer on a liner path through the scientific process and the evidence to support the theory of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thinking.

Each of the main sections on the Evolution website is equally well-developed, with materials that support a variety 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 its general textual content. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the large web site.

For instance the page "Coral Reef Connections" provides an overview of coral relationships and their interactions with other organisms, then concentrates on a specific clam that is able to communicate with its neighbours and respond to changes in water conditions that take place at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to many topics in evolutionary biology. The material also provides an overview of the importance of natural selection as well as 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 rich collection supports teaching evolution across the disciplines of life science.

One resource, the companion to PBS's television series Understanding Evolution is an excellent example of an Web site that provides depth and breadth in terms of its educational resources. The site offers a range of interactive learning modules. It also features a "bread crumb structure" that helps students move away from the cartoon style of Understanding Evolution and onto elements of this vast website that are closely linked to the worlds of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page that highlights John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related to evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives set out in the standards for biology. It contains seven videos specifically designed for classroom use. They are available to stream or purchase as DVDs.

A variety of crucial questions remain at the core of evolutionary biology, including what causes evolution to occur and the speed at which it occurs. This is particularly true in the case of human evolution, where it was difficult to reconcile religious beliefs that held that humanity has a special place in creation and a soul with the notion that human beings have innate physical traits evolved from the apes.

In addition there are a variety of ways in which evolution could be triggered with natural selection being the most popular theory. Scientists also study other kinds like mutation, genetic drift, and sexual selection.

Many fields of inquiry have a conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, others haven't.
