Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, there are still a lot of misconceptions regarding evolution. Pop science nonsense has led people to believe that biologists aren't believers in evolution.

This rich website - companion to the PBS series - provides teachers with materials which support evolution education and help avoid the kinds of myths that make it difficult to understand. It's laid out in a nested "bread crumb" format for ease of navigation and 에볼루션 게이밍 orientation.

Definitions

It's not easy to properly teach evolution. It is often misunderstood by non-scientists, and even some scientists use a definition that confuses the issue. This is particularly true when it comes to discussions on the definition of the word itself.

As such, it is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful way. The site is a companion site to the series that first aired in 2001, but 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 gradual process. These terms help to frame the nature of evolution and its relationship to other scientific concepts. The website provides a summary of the ways in which evolution has been tested. This information can help 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 suited to a particular environment. This is a result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted traits to reproduce and 에볼루션사이트 survive.

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

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

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

Origins

Species (groups of individuals that are able to interbreed) develop through an array of natural changes in the traits of their offspring. The changes can be caused by a variety of factors, 에볼루션사이트 om the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are hyperlinks to John Endler's experiments using Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in an array of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment offers many advantages over modern observational or experimental methods for studying evolutionary phenomena. In addition to studying processes and events that occur regularly or over a long period of time, paleobiology is able to examine the relative abundance of various species of organisms and their distribution across geological time.

The site is divided into several routes that can be taken 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 path also reveals the most common misconceptions about evolution, 무료 에볼루션 as well as the evolution of thought.

Each of the main sections on the Evolution website is equally well-developed, and includes materials that can be used to support a variety of curriculum levels and teaching styles. In addition to the standard textual content, the site offers an extensive selection of multimedia and interactive content like videos, animations and virtual labs. The content is organized in a nested, bread crumb fashion that aids navigation and orientation on the web site.

For instance the page "Coral Reef Connections" provides an overview of coral relationships and their interaction with other organisms. Then, it zooms in on a single clam that is able to communicate with its neighbours and respond to changes in the water conditions that occur at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, offers a great introduction to many topics in evolutionary biology. The content includes a discussion on the importance of natural selection and the concept of phylogenetics as a key method for understanding the evolution of change.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A rich collection supports teaching evolution across the disciplines of life science.

One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both depth and wide range of educational resources. The site features a wide range of interactive learning modules. It also features an "bread crumb structure" that allows students to move away from the cartoon style that is used in Understanding Evolution and onto elements on this large website more closely connected to the realms of research science. For instance an animation that introduces the concept of genetic inheritance links to a page highlighting John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.

Another useful resource is the Evolution Library on this site, which has an extensive collection of multimedia assets related to evolution. The content is organized according to curricula-based paths that correspond to the learning goals set forth in biology standards. It contains seven videos specifically designed for use in the classroom, and can be streamed at no cost or purchased on DVD.

Evolutionary biology remains an area of study that poses many important questions, including the causes of 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 held that humanity has a special position in the universe and a soul with the notion that our physical traits evolved from the apes.

There are a myriad of other ways in which evolution can occur including natural selection, which is the most popular theory. Scientists also study different types such as mutation, genetic drift, and sexual selection.

While many scientific fields of study have a conflict with literal interpretations in religious texts, evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. Certain religions have reconciled their beliefs to evolution while others haven't.
