Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions regarding evolution. Pop science nonsense has led many people to believe that biologists don't believe evolution.

This rich Web site - companion to the PBS series - provides teachers with materials that support evolution education and help avoid the kinds of misinformation that can undermine it. It's organized in a "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and difficult subject to teach effectively. It is often misunderstood even by non-scientists, and even scientists use an interpretation that is confusing the issue. This is especially relevant when discussing the definition of the words.

It is therefore crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The site is a companion site to the series that first aired in 2001, but is also an independent resource. The material is presented in a nested manner that aids navigation and 에볼루션 게이밍 무료 에볼루션 바카라 무료 - redirected here - orientation.

The site defines terms like common ancestor, gradual process and so on. These terms help to define the nature and significance of evolution with other scientific concepts. The website provides a summary of the way the concept of evolution has been tested. This information can be used to dispel misconceptions that have been propagated by the creationists.

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

Adaptation is the process of changing heritable traits to be more suitable to their environment. This is the result of natural selection. It occurs when organisms that are more adaptable traits are more likely to survive and reproduce than those with less adaptable characteristics.

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

Deoxyribonucleic acid: A huge biological molecule that holds the information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, called 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 include the interaction between predator and prey or host and parasite.

Origins

Species (groups that can crossbreed) develop by a series of natural variations in their offspring's traits. The causes of these changeshere are links to John Endler’s experiments with guppies. They illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology, the study of these creatures within their natural environment offers many advantages over modern observational or research methods for studying evolutionary phenomena. In addition to exploring processes and events that take place regularly or over a lengthy period of time, paleobiology can be used to analyze the relative abundance of various groups of organisms and their distribution in space over geological time.

The site is divided up into various options to learn about evolution. One of these paths, "Evolution 101," walks the reader through the complexities and 에볼루션 코리아 evidence of evolution. The path also explores misconceptions regarding evolution, and the background of evolutionary thought.

Each of the other main sections of the Evolution site is equally well developed, with materials that support a variety of educational levels and pedagogical styles. In addition to the general textual content, the site features a wide range of multimedia and interactive content like videos, animations and virtual labs. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation on the Web site.

For instance, the page "Coral Reef Connections" provides an overview of the relationships between corals and 에볼루션 바카라 무료 their interactions with other organisms, then zooms in on a single clam that is able to communicate with its neighbors and react to changes in the water conditions that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to a variety of topics in evolutionary biology. The material includes an explanation of the role of natural selectivity and the concept phylogenetics analysis as a key tool for understanding evolutionary changes.

Evolutionary Theory

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

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that provides depth as well as breadth in terms of its educational resources. The site features a wealth of interactive learning modules. It also has a "bread crumb structure" that helps students move away from the cartoon style that is used in Understanding Evolution and onto elements on this site that are more closely connected to the fields of research science. Animation that introduces the concept of genetics is linked to a page that highlights John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.

Another resource that is worth mentioning is the Evolution Library on this site, which has an extensive library of multimedia resources related to evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning goals set forth in the standards for biology. It includes seven short videos designed for classroom use. These can be streamed or purchased as DVDs.

A number of important questions remain at the core of evolutionary biology, including the factors that trigger evolution and the speed at which it occurs. This is particularly relevant for humans' evolution which was a challenge to reconcile religious beliefs that humans have a distinct place in creation and a soul, with the notion that human beings have innate physical traits were derived from apes.

There are a myriad of other ways evolution can occur including natural selection, which is the most well-known theory. Scientists also study other kinds like mutation, genetic drift, and sexual selection.

While many fields of scientific 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 notions of evolution, others have not.
