Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. People who have taken in popular science myths often assume that biologists claim they do not believe in evolution.

This rich Web site - companion to the PBS series offers teachers with resources that promote evolution education and avoid the kinds of misconceptions that undermine it. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complex and challenging subject to teach effectively. Non-scientists often misunderstand the subject, 에볼루션 카지노 and some scientists even use a definition that confuses it. This is especially relevant to discussions about the meaning of the word itself.

As such, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site is a companion to the show that premiered in 2001, but it also functions as an independent resource. The material is presented in a nested manner that aids navigation and orientation.

The site defines terms such as common ancestor, gradual process and so on. These terms help frame the nature and relationship of evolution with other scientific concepts. The site also provides an overview of how the concept of evolution has been tested and verified. This information can be used to dispel the myths that have been created by the creationists.

It is also possible to find a glossary of terms that are used in evolutionary biology. These terms include:

Adaptation: The tendency of heritable traits to become better adaptable to a specific environment. This is a result of natural selection. It occurs when organisms that are better adapted characteristics are more likely to survive and reproduce than those with less adapted traits.

Common ancestor: The most recent common ancestor of two or more species. The common ancestor can be identified by studying the DNA of the species.

Deoxyribonucleic Acid: A massive biological molecular that contains the information needed for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, 에볼루션 슬롯게임 called chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is a relationship between two species in which the evolution of one species are influenced evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey, or parasite and 에볼루션 바카라사이트 (visit the following page) host.

Origins

Species (groups of individuals that are able to interbreed) evolve through natural changes in the characteristics of their offspring. These changes can be caused by various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental circumstances, such as changes in the climate or competition for food resources and habitat can slow or speed up the process.

The Evolution site traces the emergence of a number of different animal and plant groups through time with a focus on the key transitions that occurred in the history of each group. It also focuses on the human evolutionary roots and humans, a subject that is especially important for students to know.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. One of them was the infamous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap when it was published in 1858, which was a year following the initial edition of The Origin. Origin.

While the site focuses on biology, 에볼루션 게이밍 it offers a lot of information on geology and paleontology. The most impressive features of the website are a timeline of events that show how geological and 에볼루션 사이트바카라, 2Ch-Ranking.Net, climatic conditions have changed over time and an interactive map of the distribution of some of the fossil groups featured on the site.

The site is a companion to a PBS television series, but it can also be used as a resource for teachers and students. The site is well-organized, and provides easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's support) and the more specific features of the museum website. These links facilitate the transition 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, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants and insects. Paleobiology is the study of these creatures within their natural environment and has numerous advantages over modern observational and experimental methods of examining evolutionary phenomena. Paleobiology focuses on not just the processes and events that happen frequently or over time, but also the relative abundance and distribution of different species of animals in space throughout the geological time.

The website is divided into several optional pathways to understanding evolution, including "Evolution 101," which takes the viewer on a line through the nature of science and the evidence to support the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought.

Each of the other sections of the Evolution site is equally created, with resources that can support a variety of curriculum levels and pedagogical styles. The site includes a variety of interactive and multimedia resources that include animations, video clips and virtual labs as well as general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the vast website.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interactions with other organisms and then is enlarged to show one clam that is able to communicate with its neighbors and react to changes in conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages, gives a good introduction to a variety of topics in evolutionary biology. The content includes an explanation of the importance of natural selection and the concept of phylogenetics analysis, an important method for understanding the evolution of changes.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A rich collection supports teaching evolution across all disciplines of life sciences.

One resource, the companion to PBS's television series Understanding Evolution is an excellent example of a Web site that provides the depth and the breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also has a nested "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely linked to the field of research science. Animation that introduces the concept of genetics, which links to a page about John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.

The Evolution Library on this website has a huge multimedia library of resources that are associated with evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives outlined in the standards for biology. It contains seven short videos intended for use in the classroom. These can be streamed or purchased as DVDs.

A variety of crucial questions remain at the core of evolutionary biology, including what causes evolution to occur and the speed at which it occurs. This is particularly relevant in the case of human evolution where it was a challenge to reconcile religious beliefs that humanity has a special place in creation and a soul, with the notion that our physical traits were derived from the apes.

Additionally there are a myriad of ways that evolution could be triggered and natural selection is the most widely accepted theory. However scientists also study other kinds of evolution, such as mutation, genetic drift and sexual selection, among others.

While many scientific fields of study are in conflict with the literal interpretations of religious texts, evolution biology has been the subject of intense debate and resistance from religious fundamentalists. Certain religions have embraced their beliefs to evolution while others haven't.
