Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions persist about evolution. Pop science nonsense has led people to believe that biologists aren't believers in evolution.

This rich website - companion to the PBS series - provides teachers with materials that support evolution education and avoid the kinds of misconceptions that 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 well. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. This is especially relevant when discussing the meaning of the words themselves.

It is essential to define terms that are used in evolutionary biology. The website for the PBS show, 에볼루션 룰렛 Understanding Evolution, does this in a clear and useful manner. The website is a companion to the series that first aired in 2001, but it also functions as an independent resource. The content is presented in a way that aids navigation and orientation.

The site defines terms such as common ancestor and gradual process. These terms help to frame the nature of evolution as well as its relation to other scientific concepts. The site gives a comprehensive overview of the manner the concept of evolution has been tested. This information can be used to dispel misconceptions 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 for hereditary traits to become more suited to a particular environment. This is the result of natural selection. It occurs when organisms with better adapted traits are more likely survive and reproduce than those with less adaptable characteristics.

Common ancestor: 에볼루션 룰렛 The most recent common ancestor of two or more 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 contained in nucleotides arranged in sequences that are strung together to form long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information inside 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 interaction between predator and prey or parasite and host.

Origins

Species (groups of individuals that can interbreed) evolve through natural changes in the traits of their offspring. These changes are caused by a variety of factors such as natural selection, genetic drift, and gene pool mixing. The development of new species can take thousands of years. Environmental conditions, like changes in the climate or competition for food or habitat can impede or accelerate the process.

The Evolution site tracks the evolution of a variety of animal and plant groups through time with a focus on the key transitions that occurred in the evolution of each group's history. It also explores the human evolutionary roots and humans, a subject that is especially important for students to understand.

Darwin's Origin was published in 1859, when only a handful of antediluvian fossils of human beings had been discovered. The famous skullcap, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap when it was published in 1858, one year following the initial edition of The Origin. Origin.

The site is mostly a biology site however, it also has many details on geology and 바카라 에볼루션 카지노 (Shenasname.Ir) paleontology. The site offers numerous features that are particularly impressive, such as 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.

While the site is a companion piece to the PBS television series, it also stands on its own as a valuable source for teachers and students. The site is well-organized and offers easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features on the museum's website. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are links to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology, the study of these creatures within their geological environment offers many advantages over the current observational or experimental methods for studying evolutionary processes. Paleobiology can examine not only processes and events that happen frequently or over time, but also the relative abundance and distribution of different species of animals across geological time.

The website is divided into various ways to learn about 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 course also focuses on misconceptions about evolution, as well as the history of evolutionary thinking.

Each of the other main sections of the Evolution site is equally well developed, with materials that support a variety of curriculum levels and pedagogical styles. In addition to the general textual content, the site offers an extensive selection of interactive and multimedia resources including videos, animations, and virtual laboratories. The breadcrumb-like organization of the content aids in navigation and orientation on the vast web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides an overview of coral relationships, their interaction with other organisms and then is enlarged to show one clam, which is able communicate with its neighbors and react to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great introduction to many topics in evolutionary biology. The information also includes an overview of the importance of natural selection and 에볼루션 룰렛 (visit the following site) the concept of phylogenetic analysis, which is a crucial tool for understanding the evolution of changes.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A vast collection of resources helps teachers teach about evolution across the life sciences.

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth as well as breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also has an "bread crumb structure" that assists students in moving away from the cartoon-like style of Understanding Evolution and onto elements on this large website more closely related to the fields of research science. An animation that introduces students to the concept of genetics is linked to a page about John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.

The Evolution Library on this website contains a large multimedia library of assets related with evolution. The content is organized according to curriculum-based pathways that correspond to the learning goals set forth in biology standards. It contains seven videos that are designed for classroom use. They can be streamed or purchased as DVDs.

A number of important questions remain in the midst of evolutionary biology, including what triggers evolution and the speed at which it occurs. This is particularly true for the evolution of humans which was a challenge to reconcile religious beliefs that humanity has a special position in the universe and a soul with the idea that innate physical traits originated from apes.

There are a myriad of other ways evolution can occur, with natural selection as the most well-known theory. However scientists also study different kinds of evolution, such as mutation, genetic drift, and sexual selection, among other things.

While many scientific fields of inquiry have a conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions have not.
