Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. People who have absorbed pop science nonsense often assume that biologists claim they don't believe in evolution.

This rich Web site - companion to the PBS series - provides teachers with materials which support evolution education and avoids the kinds of myths that make it difficult to understand. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

Evolution is a complex and challenging subject to teach effectively. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition that confuses it. This is especially true when discussing the nature of the words themselves.

It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. It is an accompanying site for the 2001 series, and also a resource of its own. The material is presented in a nested manner that assists in navigation and orientation.

The site defines terms such as common ancestor (or common ancestor), gradual process and adaptation. These terms help to define the nature and significance of evolution to other concepts in science. The website then provides an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel myths created by creationists.

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

Adaptation is the tendency of heritable traits to be 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 traits to reproduce and survive.

Common ancestor: The most recent common ancestor of two or more different species. The common ancestor can be identified through analyzing the DNA of the species.

Deoxyribonucleic Acid: A massive biological molecular that holds the information required for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

Coevolution is a relationship between two species in which the evolution of one species are influenced by evolutionary changes in the other. Coevolution can be observed through the interaction between predator and prey, or parasite and hosts.

Origins

Species (groups of individuals that are able to interbreed) evolve through natural changes in the traits of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, like climate changes or competition for food and habitat can impede or accelerate the process.

The Evolution site tracks the development of a number of different species of plants and animals over time with a focus on the key transitions that occurred in each group's history. It also examines the evolution of humans and is a subject of particular importance to students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, just 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 focuses on biology, it also includes a good deal of information on geology and paleontology. Among the best features on the site are a set of timelines that show how climatic and geological conditions have changed over time and a map of the distribution of some fossil groups that are featured on the site.

The site is a companion for a PBS television series, but it could also be used as an educational source for teachers and students. The site is well organized and provides clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks facilitate the move from the cartoon-like 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 illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of plants, 에볼루션 바카라사이트 animals, and insects. Paleobiology is the study of these creatures in their geological context and has a number of advantages over modern observational and experimental methods of examining evolutionary phenomena. Paleobiology can examine not only the process and events that occur regularly or over time, but also the distribution and 에볼루션 바카라사이트 frequency of various animal groups in space over the course of the geological time.

The Web site is divided into various pathways to understanding evolution which include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence that supports the theory of evolution. The path also examines myths about evolution, and the background of evolutionary thinking.

Each of the main sections on the Evolution website is equally well-developed, and includes materials that are suited to a variety of curriculum levels and teaching styles. The site has a range of interactive and multimedia content, including animations, video clips and virtual labs, in addition to its general textual content. The content is organized in a nested, bread crumb style that facilitates navigation and orientation on the Web site.

For instance, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms. It then concentrates on a specific clam that is able to communicate with its neighbors and react to changes in the water conditions at the level of the reef. This page, as well as the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a broad spectrum of topics in evolutionary biology. The content also includes a discussion on the significance of natural selectivity and 에볼루션 무료체험 코리아 (http://www.stes.tyc.Edu.tw/) the concept of phylogenetics as a key tool to understand evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A rich collection of resources can help teachers teach about evolution across all life sciences.

One resource, 에볼루션 사이트 the companion to PBS's television show Understanding Evolution is an excellent example of a Web site that provides depth as well as wide range of educational resources. The site features a wide 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 massive website that are more closely tied to the world of research science. For instance an animation that introduces the concept of genetic inheritance links to a page that highlights John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

Another useful resource is the Evolution Library on this web website, which includes an extensive library of multimedia assets that are related to evolution. The content is organized according to curricula-based pathways that correspond to the learning objectives outlined in the biology standards. It includes seven short videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD.

Evolutionary biology is an area of study that poses many important questions, such as what triggers evolution and how quickly it happens. This is particularly true for 에볼루션 슬롯 human evolution, where it's been difficult to reconcile the notion that the physical traits of humans evolved from apes, and the religious beliefs that claim that humanity is unique among living things and has an enviable place in creation with soul.

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

While many fields of scientific study conflict with literal interpretations in religious texts, the concept of evolution biology has been the subject of intense debate and opposition from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, but others haven't.
