A Help Guide To Evolution Site From Start To Finish

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions persist regarding evolution. People who have been exposed to pop science nonsense often assume that biologists claim they do not believe in evolution.

This site, which is a companion to the PBS series - provides teachers with materials which support evolution education and avoids the kinds of misconceptions that hinder it. It's organized in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to teach evolution well. It is often misunderstood by non-scientists, and even some scientists are guilty of using an interpretation that is confusing the issue. This is especially relevant to discussions on the nature of the word.

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

The site defines terms such as common ancestor, the gradual process, 에볼루션 블랙잭 게이밍 (www.meetme.com) and adaptation. These terms help define the nature and significance of evolution with other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and confirmed. This information can help dispel myths that are created by the creationists.

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

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

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

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

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

Origins

Species (groups which can interbreed) develop by a series of natural variations in their offspring's traits. These changes are caused by a variety of factors, including natural selection, genetic drift and mixing of gene pools. The development of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food or habitat, can slow or accelerate the process.

The Evolution site traces the emergence of a variety of groups of animals and plants over time with a focus on the key shifts that occurred throughout the history of each group. It also examines the evolution of humans and is a subject of particular importance to students.

Darwin's Origin was published in 1859, when just a few antediluvian fossils of humans were discovered. The famous skullcap, along with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap when it was published in 1858, a year following the initial edition of The Origin.

While the site is focused on biology, it also includes a good deal of information about geology as well as paleontology. The website has a number of features that are particularly impressive, such as a timeline of how climate and 에볼루션게이밍 geological conditions have changed over time. It also features an interactive map that shows the location of fossil groups.

Although the site is a companion to the PBS television show however, it can stand on its own as a great source 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 of the museum's website. These hyperlinks make it easy to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are links to John Endler's research with Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to a variety of animals, plants and insects. Paleobiology is the study of these creatures within their natural environment, has many advantages over modern observational or experimental methods of studying evolutionary processes. Paleobiology can examine not only the process and events that happen regularly or over time but also the relative abundance and distribution of different species of animals across the geological time.

The Web site is divided into several optional pathways to understanding evolution that include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence to support the theory of evolution. The path also explores misconceptions about evolution, and the background of evolutionary thought.

Each of the other main sections of the Evolution site is equally well constructed, with materials that can be used to support a range of educational levels and pedagogical styles. In addition to the standard textual content, 에볼루션 바카라 체험 (what is it worth) the site features a wide range of interactive and multimedia resources including videos, animations and virtual laboratories. The content is presented in a nested bread crumb style that facilitates navigation and orientation within the large web site.

For example the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms, then zooms in on a single clam that can communicate with its neighbors and respond to changes in water conditions that occur at the reef level. This page, as well as the other multidisciplinary interactive and multimedia 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 which is a crucial tool to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A vast collection of books helps in teaching evolution across the life science disciplines.

One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that offers both depth and breadth in its educational resources. The site offers a range of interactive learning modules. It also features an embedded "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. For instance an animation that explains the notion of genetic inheritance leads to a page that highlights John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website is a vast multimedia library of materials that deal to evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives set out in the biology standards. It contains seven videos intended for use in the classroom. They can be viewed online or purchased as DVDs.

A number of important questions remain at the core of evolutionary biology, such as what triggers evolution and how fast it occurs. This is particularly true for the evolution of humans where it was a challenge to reconcile religious beliefs that held that humanity has a unique position in the universe and a soul with the notion that our physical traits were derived from the apes.

There are a variety of other ways evolution can take place and natural selection being the most widely accepted theory. However scientists also study different kinds of evolution like mutation, genetic drift, and sexual selection, among others.

While many scientific fields of inquiry conflict with 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 ideas of evolution, others haven't.
