Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. People who have taken in popular science myths often assume that biologists are saying they don't believe in evolution.

This rich website - companion to the PBS series It provides teachers with materials which support evolution education and avoid the kinds of misinformation that can hinder it. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to effectively teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition which confuses it. This is particularly applicable to debates about the nature of the word.

Therefore, it is 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 helpful manner. The site is a companion site to the show which first aired in 2001, but it also functions as an independent resource. The material is presented in a nested manner that assists in navigation and orientation.

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

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

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

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

Deoxyribonucleic Acid: A large biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution: A relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution is evident through the interaction between predator and prey, or parasite and hosts.

Origins

Species (groups of individuals who can interbreed) develop through an array of natural changes in the characteristics of their offspring. 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 conditions, such as climate changes or competition for food resources and habitat, can slow or accelerate the process.

The Evolution site tracks through time the emergence of various groups of animals and plants, focusing on major transitions within each group's past. It also focuses on human evolution, which is a topic that is particularly important for 에볼루션 바카라 체험 무료체험 (made a post) students.

Darwin's Origin was written in 1859, at a time when only a handful of antediluvian fossils of human beings had been discovered. The skullcap that is famous, along with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year after the first edition of the Origin appeared, it is very unlikely that Darwin had ever heard of it.

While the site focuses on biology, it includes a good deal of information on geology and paleontology. The most impressive features on the site are a series of timelines that show how geological and climatic conditions have changed over time as well as an outline of the geographical distribution of some of the fossil groups featured on the site.

While the site is a companion to a PBS television show however, it can stand on its own as a valuable source for teachers and students. The site is very well-organized and has clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. In particular there are hyperlinks to John Endler's research with Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of plants, 에볼루션 카지노사이트 (moon-sullivan-4.technetbloggers.de published a blog post) animals and insects. Paleobiology is the study of these creatures in their geological context and has many advantages over the modern observational and research methods in its exploration of evolutionary processes. In addition to examining processes and 에볼루션 무료체험 events that take place frequently or over a long period of time, paleobiology can be used to analyze the relative abundance of various species of organisms and their distribution across the geological time.

The website is divided into various paths to learning evolution that include "Evolution 101," which takes the viewer on a line through the nature of science and the evidence supporting the theory of evolution. The path also explores misconceptions about evolution and also the history of evolutionary thought.

Each of the other sections of the Evolution site is similarly created, with resources that support a variety of curriculum levels and pedagogical styles. In addition to the general textual content, the site features an extensive selection of interactive and multimedia resources like videos, animations and virtual laboratories. The content is organized in a nested, bread crumb-like fashion that helps with 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, it concentrates on a specific clam that is able to communicate with its neighbors and respond to changes in water conditions at the level of the reef. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to many topics in evolutionary biology. The information also includes a discussion of the role of natural selection and the concept of phylogenetic analysis which is an important method to understand evolutionary changes.

Evolutionary Theory

For biology students the concept of evolution is a major thread that binds all branches of the field. A rich collection supports teaching evolution across all life science disciplines.

One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides depth and a variety of educational resources. The site has a wide array of interactive learning modules. It also features an embedded "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the world of research science. An animation that introduces students to the concept of genetics is linked to a page about John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.

Another resource that is worth mentioning is the Evolution Library on this Web website, which includes an extensive multimedia library of items related to evolution. The contents are organized into curricula-based pathways that correspond to the learning goals established in the standards for biology. It contains seven videos designed specifically for use in the classroom, and can be streamed at no cost or purchased on DVD.

A variety of crucial questions remain at the heart of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is especially true for the evolution of humans where it was a challenge to reconcile religious beliefs that held that humanity has a unique place in the creation and a soul, with the notion that human beings have innate physical traits originated from the apes.

In addition, there are a number of ways that evolution could occur with natural selection being the most widely accepted theory. However scientists also study other types of evolution such as mutation, genetic drift and sexual selection, among others.

Many fields of inquiry are in conflict with the literal interpretations of the Bible Evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the theories of evolution, other religions aren't.
