Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science nonsense has led many people to think that biologists don't believe in evolution.

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

Definitions

Evolution is a complicated and challenging subject to teach well. It is often misunderstood by non-scientists and even some scientists are guilty of using definitions that confuse the issue. This is particularly applicable to discussions on the meaning of the word itself.

It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The site serves as an accompanying site for the 2001 series, and also a resource of its own. The information is presented in an organized manner that makes it easier to navigate and understand.

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 concepts in science. The site provides an overview of the manner in which 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 which includes terms used in evolutionary biology. These terms include:

Adaptation: The tendency for hereditary traits to become more suitable to a particular setting. This is due to natural selection. It occurs when organisms that are better adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.

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

Deoxyribonucleic Acid: A huge biological molecular containing the necessary information for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are the reason behind 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. Examples of coevolution are the interactions between predator and prey or host and parasite.

Origins

Species (groups that can crossbreed) develop through a series of natural changes in their offspring's traits. These changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The development of a new species can take thousands of years, and the process can be slowed down or accelerated by environmental conditions such as climate change or competition for food or habitat.

The Evolution site traces through time the evolution of different species of plants and animals, focusing on major transitions in each group's past. It also examines the evolution of humans, which is a topic that is particularly important for students.

Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans had been found. Among them was the famous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, a year after the first edition of The Origin. Origin.

While the site focuses on biology, it offers a lot of information on geology and paleontology. The Web site has a number of features that are particularly impressive, including the timeline of the way that climate and geological conditions have changed over the course of time. It also features an interactive map that shows the location of fossil groups.

The site is a companion to a PBS TV series but it could also be used as an educational resource by teachers and students. The site is well-organized and 에볼루션바카라 provides easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features on the museum's website. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler’s experiments with guppies. They demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of plants, animals and insects. Paleobiology is the study of these creatures in their geological environment offers many advantages over modern observational or research methods for studying evolutionary processes. Paleobiology focuses on not only processes and events that take place regularly or over time but also the relative abundance and distribution of different groups of animals in space throughout the geological time.

The site is divided into several optional paths to learning evolution which include "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence to support the theory of evolution. The path also reveals common misconceptions about evolution as well as the evolution theory's history.

Each of the main sections on the Evolution website is equally well-designed, with materials that support a variety curriculum levels and teaching styles. The site offers a wide array of interactive and multimedia resources that include video clips, animations and virtual labs in addition to general textual content. The content is organized in a nested, 무료 에볼루션 bread crumb fashion that aids navigation and orientation on the 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 water conditions at the level of the reef. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a broad variety of topics in evolutionary biology. The content also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis which is a key method to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A wide range of resources can help teachers teach about evolution across all life sciences.

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides the depth and the wide range of educational resources. The site offers 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 huge site that are closer to the world of research science. Animation that introduces the concept of genetics is linked to a page that highlights John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.

Another useful resource is the Evolution Library on this site, 에볼루션 바카라 체험 which has an extensive library of multimedia items that are related to evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives set out in the standards for biology. It includes seven short videos specifically designed for use in the classroom, and can be streamed for 에볼루션 룰렛 무료 바카라 (Woodard-Gamble-2.Blogbright.Net) no cost or purchased on DVD.

Evolutionary biology is a field of study that poses many important questions, including what causes evolution and how fast it takes place. This is especially true for the evolution of humans which 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 evolved from the apes.

In addition there are a myriad of ways that evolution can be triggered, with natural selection being the most popular theory. Scientists also study other types such as genetic drift and sexual selection.

Although many scientific fields of study conflict with literal interpretations found in religious texts, the concept of evolution biology has been a source of intense debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, others have not.
