Evolution Site - Teaching About Evolution

Despite the best efforts by biology teachers, there are still misconceptions about evolution. People who have been exposed to the nonsense of pop science often believe that biologists are saying they do not believe in evolution.

This rich website - companion to the PBS series - provides teachers with materials which support evolution education and avoid the kinds of myths that make it difficult to understand. It's laid out in a "bread crumb" format to make navigation and orientation easier.

Definitions

Evolution is a complicated and difficult subject matter to teach effectively. It is often misunderstood even by non-scientists, 에볼루션 슬롯게임 무료 바카라 (https://olps.co.za/wiki/user:evolution8539) and even some scientists use an interpretation that is confusing the issue. This is particularly relevant to discussions on the definition of the word itself.

It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site is both a companion for the 2001 series, 무료 에볼루션 and it is also a resource on its own. The material is presented in a structured manner that makes it simpler to navigate and understand.

The site defines terms like common ancestor, gradual process and so on. 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 in which evolution has been tested. This information can be used to dispel the myths that have been engendered by the creationists.

You can also access a glossary that contains terms used in evolutionary biology. These terms include:

Adaptation: The tendency of heritable characteristics to become more adaptable to a specific environment. This is due to natural selection. It occurs when organisms that have better adapted characteristics are more likely to survive and reproduce than those with less adapted traits.

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

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

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

Origins

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

The Evolution site traces through time the evolution of various species of plants and animals with a focus on major changes in each group's past. It also focuses on the evolutionary origin of humans which is crucial for students to understand.

Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans had been found. One of them was the infamous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was published in 1858, one year following the initial edition of The Origin. Origin.

The site is mostly an online biology resource however it also includes many details on paleontology and geology. The Web site has numerous features that are especially impressive, including an overview of how climate and geological conditions have changed over the course of time. It also includes an interactive map that shows the location of fossil groups.

While the site is a companion piece to a PBS television series however, it can stand on its own as an excellent resource for teachers and students. The site is well-organized and provides easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features on the museum's website. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are also links to John Endler's experiments with guppies, which illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life has produced an array of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and has numerous advantages over the current observational and experimental methods of examining evolutionary phenomena. In addition to studying processes and events that occur regularly or over a lengthy period of time, paleobiology is able to study the diversity of groups of organisms and their distribution in space over the course of geological time.

The website is divided into several paths that can be chosen to gain knowledge about evolution. One of these paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The path also examines myths about evolution, and 무료에볼루션 the background of evolutionary thinking.

Each of the other main sections of the Evolution site is equally created, with resources that support a variety of educational levels and pedagogical styles. In addition to the general textual content, the site also has a wide range of multimedia and interactive content, such as videos, animations, and virtual laboratories. The content is presented in a nested bread crumb style that facilitates navigation and orientation on the Web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of the coral's relationships and their interactions with other organisms and zooms in on a single clam, which can communicate with its neighbours and respond to changes in conditions of the water at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The content also includes an explanation of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool for understanding the evolution of change.

Evolutionary Theory

For biology students evolution is a crucial thread that connects all the branches of the field. 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 an Web page that offers both depth as well as wide range of educational resources. The site features a wealth of interactive learning modules. It also has a "bread crumb structure" that assists students in moving away from the cartoon-like style used in Understanding Evolution and onto elements on this site that are more closely connected to the fields of research science. For example an animation that explains the notion of genetic inheritance leads to a page that highlights John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives set out in the biology standards. It contains seven short videos specifically intended for use in the classroom. These can be viewed online or purchased as DVDs.

Evolutionary biology remains an area of study that poses many important questions, including what triggers evolution and how quickly it takes place. This is particularly true for human evolution, which has made it difficult to reconcile the idea that the physical traits of humans evolved from apes, and the religious beliefs that hold that humanity is unique in the universe and has an exclusive place in the creation, with a soul.

In addition, there are a number of ways that evolution can 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 others.

Many 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 certain religions have managed to reconcile their beliefs with the theories of evolution, other religions aren't.
