Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.

This rich Web site, which is a complement to the PBS program offers teachers resources that support the evolution of education, while avoiding the kinds of misconceptions which undermine it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complex and difficult 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 particularly true when discussing the nature of the words themselves.

It is therefore important to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful manner. The site is both an accompanying site for the 2001 series, but also a resource of its own. The material is presented in a way which aids navigation and orientation.

The site defines terms like common ancestor and gradual process. These terms help define the nature and significance of evolution to other scientific concepts. The site also provides an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel the myths created by creationists.

You can also consult a glossary that includes terms used in evolutionary biology. These terms include:

Adaptation is the process of changing hereditary traits to become more suitable to their environment. This is due to natural selection. It occurs when organisms that have more adaptable traits are more likely survive and reproduce than those with less adaptable traits.

Common ancestor (also called common ancestor) The most recent ancestor that is shared by two or more species. By studying the DNA of these species, it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A large biological molecular containing the information needed for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution are the interactions between predator and prey or the parasite and the host.

Origins

Species (groups which can interbreed) change by a series of natural variations in their offspring's traits. Changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, such as climate changes or competition for food resources and habitat can slow or speed up the process.

에볼루션 바카라 distribution of different groups of animals in space throughout geological time.

The Web site is divided into several optional ways to learn about evolution, including "Evolution 101," which takes the viewer on a line through the scientific process and the evidence to support the theory of evolution. The path also reveals 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 support a variety levels of curriculum and teaching methods. In addition to general textual content, the site also has a wide range of multimedia and interactive content like video clips, animations, and virtual laboratories. The breadcrumb-like structure of the content helps with navigation and orientation on the massive Web site.

The page "Coral Reef Connections" For instance, it gives a brief overview of the coral's relationships, their interaction with other organisms and then zooms in on one clam, which is able to communicate with its neighbours and respond to changes in conditions of the water at the reef level. This page, along with the other multidisciplinary, 에볼루션 사이트 multimedia, and interactive pages on the site, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The content includes a discussion on the importance of natural selection and the concept of phylogenetics analysis, an important tool to understand evolutionary change.

Evolutionary Theory

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

One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides depth and a variety of educational resources. The site has a variety of interactive learning modules. It also has a "bread crumb structure" that assists students in moving away from the cartoon style used in Understanding Evolution and 에볼루션 사이트 onto elements of this vast website that are closely connected to the fields of research science. An animation that introduces the concept of genetics is linked to a page highlighting John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.

Another resource that is worth mentioning is the Evolution Library on this site, which has an extensive library of multimedia resources related to evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives set out in the biology standards. It includes seven short videos designed specifically for classroom use, which can be streamed for free or 에볼루션 무료체험 purchased on DVD.

A number of important questions remain at the heart of evolutionary biology, including what causes evolution to occur and how fast it occurs. This is particularly relevant for the evolution of humans where it was a challenge to reconcile religious beliefs that humanity has a special position in the universe and 에볼루션 사이트 a soul, with the idea that innate physical traits originated from apes.

In addition there are a myriad of ways that evolution could occur with natural selection being the most widely accepted theory. However scientists also study other types of evolution such as mutation, genetic drift and sexual selection, among other things.

Many fields of inquiry conflict with the literal interpretations of the Bible Evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, while others haven't.
