Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution persist. People who have taken in the nonsense of pop science often believe that biologists don't believe in evolution.

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

Definitions

It is difficult to teach evolution well. Many non-scientists are unable to grasp the concept and 에볼루션 바카라 무료체험 some scientists use a definition which confuses it. This is particularly true when discussing the meaning of the words themselves.

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

The site defines terms like common ancestor and the gradual process. These terms help to frame the nature of evolution as well as its relation to other scientific concepts. The site provides an overview of the way the concept of evolution has been tested. This information can be used to dispel the myths that have been propagated by creationists.

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

Adaptation: The tendency of hereditary traits to become more suited to a particular environment. This is the result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adaptable traits to survive and reproduce.

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

Deoxyribonucleic acid: A huge biological molecule that contains information needed for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, referred to as chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is the relationship between two species where evolution of one species are influenced evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey, or the parasite and the host.

Origins

Species (groups of individuals who can interbreed) develop through an array of natural changes in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, such as climate changes or competition for food and habitat can impede or accelerate the process.

The Evolusects. Paleobiology is the study of these creatures within their geographical context and offers many advantages over the modern observational and research methods in its exploration of evolutionary processes. Paleobiology can examine not just the processes and events that happen regularly or over time but also the distribution and frequency of different groups of animals across the geological time.

The website is divided into various pathways to understanding evolution that include "Evolution 101," which takes the user on a linear path through the nature of science and the evidence supporting the theory of evolution. The course also focuses on misconceptions regarding evolution, and the background of evolutionary thinking.

Each of the other sections of the Evolution site is equally well constructed, with materials that support a variety of different pedagogical levels and curriculum levels. The site includes a variety of interactive and multimedia content, 에볼루션 사이트 바카라 무료체험 [Lewis-phillips-4.Blogbright.net] including video clips, animations and virtual labs, 에볼루션 슬롯게임 - Historydb.Date, in addition to its general textual content. The breadcrumb-like structure of the content helps with navigation and orientation on the massive Web site.

For instance the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interactions with other organisms. It then narrows down to a single clam that is able to communicate with its neighbors and respond to changes in the water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary multimedia and interactive pages, provides an excellent introduction to the many areas of evolutionary biology. The material includes an overview of the role of natural selectivity and the concept of phylogenetics which is a crucial method for understanding the evolution of change.

Evolutionary Theory

For biology students, evolution is a key thread that binds all the branches of the field. A wide selection of resources helps teachers teach evolution across all life science disciplines.

One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that provides the depth and breadth of its educational resources. The site features a wide range of interactive learning modules. It also features a "bread crumb structure" that helps students move away from the cartoon-like style used in Understanding Evolution and onto elements of this vast website that are closely related to the worlds of research science. An animation that introduces students to the concept of genetics, which links to a page about John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.

The Evolution Library on this website is a vast multimedia library of assets related to evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning goals set forth in the biology standards. It contains seven videos specifically designed for classroom use, which can be streamed at no cost or purchased on DVD.

A variety of crucial questions remain in the midst of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is especially true for human evolution, which has made it difficult to reconcile the notion that the innate physical characteristics of humans evolved from apes and religious beliefs that claim that humanity is unique among living things and holds a an enviable place in creation with soul.

There are also a number of other ways evolution can occur and natural selection being the most popular theory. However, scientists also study other kinds of evolution, such as mutation, genetic drift and sexual selection, among other things.

While many scientific fields of inquiry conflict with literal interpretations of the Bible evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, other religions have not.
