5 Evolution Site Lessons Learned From The Professionals

Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, there are still a lot of misconceptions about evolution. People who have taken in pop science nonsense often assume that biologists claim they do not believe 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 undermine it. It's organized in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

It is difficult to teach evolution well. Non-scientists often misunderstand the subject, and some scientists even use a definition which confuses it. This is particularly true when it comes to discussions about the nature of the word.

As such, 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 useful way. It is an accompanying site for the 2001 series, and also a resource of its own. The content is presented in a nested manner that assists in navigation and orientation.

The site defines terms such as common ancestor and the gradual process. These terms help to frame the nature of evolution as well as its relationship to other scientific concepts. The site gives a comprehensive overview of the manner the concept of evolution has been examined. This information can be used to dispel myths that have been engendered by the creationists.

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

Adaptation is the process of changing hereditary traits to become more suited to the environment. This is the result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adapted characteristics to survive and reproduce.

Common ancestor (also known as common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of these species.

Deoxyribonucleic acid: A massive biological molecule that contains the information necessary for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution: A relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey, or 에볼루션 바카라 사이트 바카라 (www.Youtube.com) the parasite and the host.

Origins

Species (groups of individuals that can interbreed) develop through an array 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 development of a new species may take thousands of years, and the process could be slowed down or accelerated by environmental conditions such as climate change or competition for food or habitat.

The Evolution site follows the evolution of various animal and plant groups and focuses on major changes within each group's past. It also explores the human evolutionary roots which is especially important for students to know.

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

While the site is focused on biology, it also includes a good deal of information about geology as well as paleontology. The Web site has numerous features that are especially impressive, including the timeline of how climate and geological conditions have changed over the course of time. It also includes maps that show the locations of fossil groups.

The site is a companion for a PBS television series, but it can also be used as an educational resource for teachers and students. The site is well-organized and has clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. 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 illustrate 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 is the study of these creatures within their natural environment and has many advantages over the modern observational and research methods in its exploration of evolutionary phenomena. In addition to studying processes and events that take place regularly or over a lengthy period of time, paleobiology can be used to analyze the relative abundance of different kinds of organisms as well as their distribution throughout the geological time.

The Web site is divided into several optional pathways to understanding evolution which include "Evolution 101," which takes the viewer on a line through the science of nature and the evidence supporting the theory of evolution. The path also reveals the most common misconceptions about evolution, as well as the history of evolutionary 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 educational levels and teaching styles. The site offers a wide array of interactive and multimedia content which include videos, animations, 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 vast Web site.

For example, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interaction with other organisms, then concentrates on a specific clam that is able to communicate with its neighbors and react to changes in the water conditions that take place at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a broad range of topics in evolutionary biology. The content also includes a discussion on the role of natural selectivity and the concept of phylogenetics analysis as a key tool to understand evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that runs through 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 an Web page that provides the depth and 에볼루션 the wide range of educational resources. The site has a variety of interactive learning modules. It also has an encased "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. For example an animation that explains the notion of genetic inheritance leads to a page that focuses on John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.

Another helpful resource is the Evolution Library on this web site, which contains an extensive multimedia library of resources that are related to evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives outlined in biology standards. It contains seven videos designed specifically for use in the classroom, and can be streamed at no cost or purchased on DVD.

Many important questions remain in the midst of evolutionary biology, including the factors that trigger evolution and the speed at which it occurs. This is especially true for humans' evolution where it was a challenge to reconcile religious beliefs that humanity has a unique place in the creation and 에볼루션 바카라 사이트 a soul with the idea that innate physical traits were derived from apes.

There are a variety of other ways in which evolution can take place and natural selection being the most well-known theory. Scientists also study different types such as mutation, 에볼루션 슬롯 genetic drift, and sexual selection.

While many scientific fields of study are in conflict with the literal interpretations of religious texts, the concept of evolution biology has been a source of intense debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, others haven't.
