Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, misconceptions persist about evolution. Pop science nonsense has led many people to believe that biologists don't believe evolution.

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

Definitions

It is difficult to effectively teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition which confuses it. This is particularly true when discussing the nature of the words themselves.

It is therefore essential to define the terms 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 show which first aired in 2001, but also functions as an independent resource. The content is presented in a nested manner that aids navigation and orientation.

The site defines terms such as common ancestor and the gradual process. These terms help define the nature and relationship of evolution to other scientific concepts. The website provides a summary of the way the concept of evolution has been examined. This information can help dispel the myths created by creationists.

It is also possible to access 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 a result of natural selection. Organisms that have better-adapted traits are more likely than those with less adaptable characteristics to survive and reproduce.

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

Deoxyribonucleic acid: A large biological molecule that contains information needed 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 source of new genetic information within cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and 에볼루션바카라사이트 prey, or the parasite and the host.

Origins

Species (groups which can interbreed) develop by a series of natural variations in the traits of their offspring. These changes are caused by a variety of factors that include natural selection, genetic drift and mixing of gene pools. The evolution of new species could take thousands of years. Environmental circumstances, such as changes in the climate or competition for food resources and habitat can slow or speed up the process.

The Evolution site traces the emergence of various animal and plant groups through time and focuses on the most significant shifts that occurred throughout each group's history. It also focuses on the evolutionary origin of humans which is crucial for students to know.

Darwin's Origin was written in 1859, when only a handful of antediluvian fossils of human beings had been discovered. The skullcap that is famous, 에볼루션 바카라사이트 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. Although the skullcap was not published until 1858, one year after the first edition of the Origin was published, it is highly unlikely that Darwin had heard or seen of it.

The site is primarily an online biology resource however it also includes a lot of information on paleontology and geology. One of the most appealing features of the website are a series of timelines which show how climatic and geological conditions have changed over time and a map of the distribution of a few of the fossil groups featured on the site.

The site is a companion to the PBS television series, but it could be used as a resource by teachers and students. The site is very well organized and provides clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's experiments using Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to a variety of animals, plants and insects. Paleobiology, 에볼루션 바카라사이트 the study of these creatures within their geological context offers many advantages over modern observational or research methods for exploring evolutionary processes. In addition to studying processes and events that occur regularly or over a long period of time, paleobiology is able to examine the relative abundance of various kinds of organisms as well as their distribution throughout geological time.

The site is divided up into several routes that can be taken to learn about evolution. One of the paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The course also focuses on common misconceptions about evolution as well as the evolution of thought.

Each of the other sections of the Evolution site is similarly constructed, with materials that can support a variety of different pedagogical levels and curriculum levels. In addition to the standard textual content, the site features an array of interactive and multimedia resources including videos, animations, 에볼루션 바카라사이트 and 에볼루션 바카라사이트 virtual laboratories. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation within the vast Web site.

For instance the page "Coral Reef Connections" provides an overview of coral relationships and their interaction with other organisms. Then, it concentrates on a specific clam that can communicate with its neighbors and respond to changes in the water conditions that occur at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages, gives a good introduction to a variety of topics in evolutionary biology. The material also provides an explanation of the role of natural selection as well as the concept of phylogenetic analysis, which is a key tool for understanding the evolution of change.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A vast collection of books helps in teaching evolution across all life science disciplines.

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web site that provides depth as well as wide range of educational resources. The site has a wide array of interactive learning modules. It also has a nested "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this massive website that are more closely tied to the world of research science. Animation that introduces the concept of genetics is linked to a page about John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.

The Evolution Library on this website has a huge multimedia library of materials that deal to evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning objectives outlined in the biology standards. It contains seven videos specifically designed for use in classrooms, and 에볼루션 무료체험 can be streamed for free or purchased on DVD.

Evolutionary biology is still an area of study that has many important questions, including what triggers evolution and how quickly it occurs. This is especially true for the evolution of humans which was a challenge to reconcile religious beliefs that humans have a distinct position in the universe and a soul, with the idea that innate physical traits originated from the apes.

There are also a number of other ways in which evolution can take place and natural selection being the most popular theory. However, scientists also study other kinds of evolution like genetic drift, mutation, and sexual selection, among others.

Many fields of inquiry conflict with the literal interpretations of religious texts evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the theories of evolution, other religions haven't.
