Evolution Site - Teaching About Evolution

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

This rich Web site, which is a companion to the PBS program, provides teachers with materials that promote evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's organized in the "bread crumb" format to make navigation and orientation easier.

Definitions

Evolution is a complex and challenging subject to teach effectively. It is often misunderstood even by non-scientists, and even some scientists are guilty of using a definition that confuses the issue. This is especially relevant to debates about the meaning of the word itself.

As such, it is essential to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. It is an accompaniment to the 2001 series, but also a resource on its own. The content is presented in a way which aids navigation and orientation.

The site defines terms like common ancestor, gradual process and so on. These terms help frame the nature and 에볼루션바카라사이트 significance of evolution with other scientific concepts. The site gives a comprehensive overview of the manner in which evolution has been tested. This information can be used to dispel myths that have been created by creationists.

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

Adaptation is the process of changing heritable traits to become better suited to an environment. This is a result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adaptable characteristics to survive and reproduce.

Common ancestor: The latest common ancestor of two or more distinct species. By analyzing the DNA from these species, it is possible to determine the common ancestor.

Deoxyribonucleic acid: A large biological molecule that contains the information necessary for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution is the relationship between two species where evolution of one species influence evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey or host and parasite.

Origins

Species (groups of individuals who can interbreed) evolve through natural changes in the traits of their offspring. These changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The evolution of a new species may take thousands of years, and the process could be slowed or increased by environmental factors like climate change or the competition for food or habitat.

The Evolution site follows the evolution of different groups of animals and plants and focuses on major changes in each group's history. It also examines the human evolutionary roots which is especially important for students to comprehend.

Darwin's Origin was written in 1859, when only a few antediluvian fossils of humans were discovered. One of them was the infamous skullcap and associated bones found in 1856 in 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 one year before the first edition of the Origin was published, it is very unlikely that Darwin had ever heard of it.

The site is primarily one of biology, but it also contains lots of information about paleontology and geology. The most impressive features of the Web site are a series of timelines that illustrate how climatic and geological conditions changed over time, as well as a map of the distribution of a few fossil groups listed on the site.

While the site is a companion piece to a PBS television show, it also stands on its own as a great source for teachers and students. The site is well-organized and provides easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features of the museum website. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. In particular there are links to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment offers many advantages over modern observational or 에볼루션 바카라 사이트 experimental methods for exploring evolutionary processes. Paleobiology focuses on not only the process and events that happen regularly or over time but also the distribution and frequency of various animal groups across geological time.

The Web site is divided into a variety of paths to learning evolution that 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 common misconceptions about evolution as well as the history of evolutionary thought.

Each of the other main sections of the Evolution site is similarly constructed, with materials that can be used to support a range of educational levels and pedagogical styles. In addition to general textual content, the site also has an extensive selection of interactive and multimedia resources, such as videos, animations, and virtual labs. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation on the web site.

For instance, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms. It then narrows down to a single clam that can communicate with its neighbors and respond to changes in water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary, multimedia, and 에볼루션 카지노 interactive pages on the site, provide an excellent introduction to a broad variety of topics in evolutionary biology. The content also includes a discussion on the importance of natural selection and the concept of phylogenetics analysis, an important tool for understanding evolutionary change.

Evolutionary Theory

For biology students the concept of evolution is a major thread that weaves together all the branches of the field. A rich collection supports teaching evolution across the disciplines of life science.

One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both the depth and breadth of its educational resources. The site has a wide array of interactive learning modules. It also has an "bread crumb structure" that allows students to move away from the cartoon-like style of Understanding Evolution and onto elements on this site that are more closely connected to the worlds of research science. For instance an animation that introduces the concept of genetic inheritance links to a page that focuses on John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of assets related with evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives outlined in the biology standards. It contains seven short videos designed for classroom use. These can be viewed online or purchased as DVDs.

A number of important questions remain at the core of evolutionary biology, including what causes evolution to occur and how fast it happens. 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 also a number of other ways evolution could occur including natural selection, which is the most popular theory. Scientists also study other types such as genetic drift and sexual selection.

Although many scientific fields of study are in conflict with literal interpretations found in religious texts, evolution biology has been the subject of intense debate and 바카라 에볼루션 resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, others aren't.
