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 promote evolution education and avoid the kinds of misinformation that can undermine it. It's organized in a nested "bread crumb" format to make it easy for navigation and 에볼루션 무료체험 orientation.

Definitions

Evolution is a complicated and difficult subject matter to teach well. It is often misunderstood even by non-scientists, and even some scientists have been guilty of using an interpretation that is confusing the issue. This is particularly true when discussing the nature of the words themselves.

It is therefore crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a simple and efficient way. The site is a companion site to the show which first aired in 2001, but it also functions as an independent resource. The information is organized in a manner that makes it simpler to navigate and understand.

The site defines terms like common ancestor and the gradual process. These terms help to define the nature of evolution as well as its relation to other scientific concepts. The website provides a summary of the manner that evolution has been tested. This information can help dispel myths that are created by the creationists.

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

Adaptation: The tendency of heritable characteristics to become more suitable to a particular setting. This is a result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adaptable characteristics to survive and reproduce.

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

Deoxyribonucleic acid: A large biological molecule that holds the information needed for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are responsible for 무료 에볼루션 the creation of new genetic information inside cells.

Coevolution is the relationship between two species where evolutionary changes of one species are influenced evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or the parasite and the host.

Origins

Species (groups which can interbreed) develop through a series of natural changes in the traits of their offspring. Changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, 무료 에볼루션 like climate change or competition for 무료 에볼루션 food and habitat, can slow or accelerate the process.

The Evolution site traces through time the emergence of various species of plants and animals and focuses on major changes within each group's past. It also focuses on human evolution as a subject that is particularly important to students.

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

The site is primarily an online biology resource however, it also has many details on geology and paleontology. The most impressive features on the site are a set of timelines that illustrate how geological and climatic conditions changed over time, and an outline of the distribution of some of the fossil groups featured on the site.

Although the site is a companion to the PBS television series but it also stands on its own as a great resource for teachers and students. The site is well-organized and offers easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's support) and the more specific features on the museum's website. These hyperlinks help users move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also links to John Endler's experiments with guppies that illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life on Earth has resulted in a variety of plants, animals, and insects. Paleobiology is the study of these creatures in their natural environment and has a number of advantages over the current observational and experimental methods of examining evolutionary phenomena. Paleobiology can examine not just the processes and events that occur frequently or over time, but also the relative abundance and distribution of different groups of animals in space over the course of the geological time.

The site is divided into several optional pathways to understanding evolution which include "Evolution 101," which takes the user on a linear path through the science of nature and the evidence that supports the theory of evolution. The path also explores misconceptions about evolution as well as the history of evolutionary thinking.

Each of the other major sections of the Evolution site is equally created, with resources that support a variety of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia content, including animations, 에볼루션 블랙잭; just click the up coming internet site, video clips and virtual laboratories in addition to general textual content. The content is presented in a nested bread crumb style that facilitates navigation and orientation within the large web site.

For instance the page "Coral Reef Connections" gives a brief overview of coral relationships and their interaction with other organisms. Then, it narrows down to a single clam that is able to communicate with its neighbors and respond to changes in the water conditions at the level of the reef. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The information also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis which is an important method to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that connects all branches of biology. A wide range of resources helps teachers teach about evolution across the life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that offers both depth and breadth in its educational resources. The site features a wealth of interactive learning modules. It also has an encased "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the field of research science. For example an animation that explains the concept of genetic inheritance links to a page that focuses on John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of assets related to evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives outlined in the standards for biology. It includes seven short videos designed specifically for classroom use, which can be streamed for no cost or purchased on DVD.

Evolutionary biology is still a field of study that has many important questions to answer, such as the causes of evolution and how fast it happens. This is especially applicable to human evolution which has made it difficult to reconcile the idea that the innate physical characteristics of humans evolved from apes, and the religious beliefs that hold that humans are unique among living things and holds a an exclusive place in the creation with soul.

There are also a number of other ways evolution could occur, with natural selection as the most widely accepted theory. However scientists also study different kinds of evolution, such as mutation, genetic drift, and sexual selection, among others.

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