Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution remain. People who have been exposed to popular science myths often assume that biologists don't believe in evolution.

This rich website - companion to the PBS series offers teachers with resources which support evolution education and avoids the kinds of misinformation that can undermine it. It's organized in the "bread crumb" format to make navigation and orientation easier.

Definitions

Evolution is a complicated and challenging subject to teach well. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is especially applicable to discussions on the nature of the word.

It is therefore essential to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, 에볼루션 바카라 사이트 does this in a clear and useful manner. The website is a companion to the show that premiered in 2001, but also functions as an independent resource. The content is organized in a manner that makes it simpler to navigate and comprehend.

The site defines terms like common ancestor, gradual process and so on. These terms help to frame the nature of evolution and its relation to other concepts in science. The site also provides an overview of how the concept of evolution has been tested and confirmed. This information can be used to dispel misconceptions that have been propagated by creationists.

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

Adaptation: The tendency for hereditary traits to become more suitable to a particular setting. This is the result of natural selection. Organisms with better-adapted traits are more likely than those with less adapted traits to survive and reproduce.

Common ancestor: The most recent common ancestor of two or more different species. By studying the DNA of these species, it is possible to determine the common ancestor.

Deoxyribonucleic acid: A large biological molecule that contains the information needed for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, called chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution is a relation between two species in which the evolutionary changes of one species influence evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups of individuals who can interbreed) evolve through a series of 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 climate changes or competition for food and habitat can impede or accelerate the process.

The Evolution site follows the evolutiges to the more sophisticated world of research science. In particular, there are links to John Endler's experiments with 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 is the study of these creatures in their natural environment and has a number of advantages over the current observational and experimental methods in its exploration of evolutionary processes. Paleobiology can examine not only the process and events that take place frequently or over time, but also the relative abundance and distribution of different groups of animals across geological time.

The Web site is divided into several optional pathways to understanding evolution that include "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence supporting the theory of evolution. The path also explores common misconceptions about evolution and the evolution theory's history.

Each of the main sections on the Evolution website is equally well-designed, with materials that can be used to support a variety of curriculum levels and teaching styles. In addition to the general textual content, 에볼루션사이트 the site also has an array of interactive and multimedia resources like video clips, animations, and virtual labs. The content is laid out in a nested bread crumb fashion that aids navigation and orientation on the web site.

For example the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms. It then zooms in on a single clam that can communicate with its neighbours and respond to changes in water conditions that occur at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The content also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis which is an important method to understand evolutionary changes.

Evolutionary Theory

For biology students the concept of evolution is a major thread that connects all the branches of the field. A wide range of resources supports teaching about evolution across the life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both the depth and 에볼루션바카라사이트 breadth of its educational resources. The site has a variety of interactive learning modules. It also has an "bread crumb structure" that helps students move away from the cartoon style used in Understanding Evolution and onto elements on this large website more closely related to the fields of research science. For example, an animation introducing the notion of genetic inheritance leads to a page that highlights John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of resources that are associated to evolution. The content is organized into courses that are based on curriculum and follow the learning objectives set out in biology standards. It contains seven short videos specifically intended for use in the classroom. These can be streamed or purchased as DVDs.

Evolutionary biology is an area of study that poses many important questions, including what causes evolution and how quickly it happens. This is especially applicable to human evolution where it's been difficult to reconcile the idea that the physical traits of humans were derived from apes, and the religions that believe that humanity is unique among living things and holds a a special place in creation, with a soul.

In addition there are a variety of ways in which evolution could be triggered, with natural selection being the most widely accepted theory. Scientists also study different types like mutation, genetic drift, and sexual selection.

While many scientific fields of inquiry conflict with the literal interpretations of the Bible Evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, others haven't.
