Evolution Site - Teaching About Evolution

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

This rich Web site, which is a complement to the PBS program offers teachers resources that promote evolution education, while avoiding the kinds of misconceptions which undermine it. It's laid out in the "bread crumb" format to make navigation and orientation easier.

Definitions

Evolution is a complex and difficult subject matter to teach effectively. It is often misunderstood even by non-scientists, and even some scientists use a definition that confuses the issue. This is particularly true when discussing the nature of the words themselves.

As such, it is important to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site serves as an accompaniment to the 2001 series, and also a resource on its own. The material is organized in a manner that makes it easier to navigate and understand.

The site defines terms such as common ancestor (or 에볼루션 슬롯게임 블랙잭 (weblink) common ancestor), gradual process and adaptation. These terms help frame the nature of evolution and its relation to other concepts in science. The website provides a summary of the manner the concept of evolution has been tested. This information can help dispel the myths created by creationists.

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

Adaptation: The tendency of hereditary traits to become more suitable to a particular setting. This is a result of natural selection. It occurs when organisms that are more adaptable traits are more likely survive and reproduce than those with less adaptable traits.

Common ancestor: The latest common ancestor of two or more species. By analyzing the DNA from these species, it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A large biological molecular containing the information required for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or host and parasite.

Origins

Species (groups that can interbreed) develop by a series of natural variations in their offspring's traits. These changes are caused by a variety of factors that include natural selection, genetic drift and mixing of genes. The evolution of new species can take thousands of years. Environmental circumstances, such as climate change or competition for 에볼루션코리아 food resources and habitat can impede or accelerate the process.

The Evolution site traces the emergence of a variety of species of plants and animals over time and focuses on the most significant shifts that occurred throughout each group's history. It also examines the evolutionary origin of humans which is particularly important for students to understand.

Darwin's Origin was published in 1859, when only a few antediluvian fossils of human beings had been discovered. Among them was the famous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year after the first edition of the Origin appeared, it is very unlikely that Darwin had heard or seen of it.

The site is primarily one of biology however it also includes lots of information about paleontology and geology. The Web site has several aspects that are quite impressive, such as the timeline of the way that climate and 에볼루션코리아 geological conditions have changed over time. It also features an interactive map that shows the location of fossil groups.

While the site is a companion to the PBS television show however, it can stand on its own as a valuable source for teachers and students. The site is well-organized and offers easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features on the museum's website. These hyperlinks help users move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler’s experiments with guppies that illustrate the importance 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 within their natural environment and has a number of advantages over the current observational and experimental methods for analyzing evolutionary phenomena. In addition to exploring processes and events that occur regularly or over a lengthy period of time, paleobiology is able to analyze the relative abundance of various kinds of organisms as well as their distribution throughout geological time.

The website is divided into various paths to learning evolution, including "Evolution 101," which takes the user on a linear path through the science of nature and the evidence to support the theory of evolution. The path also explores common misconceptions about evolution and the evolution theory's history.

Each of the other sections of the Evolution site is equally well constructed, with materials that can be used to support a range of curriculum levels and pedagogical styles. In addition to general textual content, the site features an array of interactive and multimedia resources, such as videos, animations, 에볼루션 무료 바카라 - weblink, and virtual labs. The content is presented in a nested bread crumb fashion that aids navigation and orientation within the vast web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides an overview of the coral's relationships, 에볼루션 바카라사이트게이밍 - Http://Bbs.Lingshangkaihua.Com/, their interaction with other organisms and zooms in to one clam that can communicate with its neighbors and react to changes in the conditions of the water that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages provides an excellent introduction to the many areas of evolutionary biology. The content also includes a discussion on the significance of natural selectivity and the concept of phylogenetics analysis, an important method for understanding the evolution of changes.

Evolutionary Theory

Evolution is a common thread that connects all branches of biology. A vast collection of resources helps teachers teach about evolution across all life sciences.

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

The Evolution Library on this website is a vast multimedia library of materials that deal to evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives outlined in biology standards. It contains seven videos designed specifically for use in classrooms, and can be streamed for free or purchased on DVD.

Evolutionary biology remains a field of study that poses many important questions, such as what causes evolution and how fast it happens. This is especially true for humans' evolution where it was a challenge to reconcile religious beliefs that held that humans have a distinct position in the universe and a soul, with the notion that our physical traits originated from the apes.

There are also a number of other ways evolution can take place and natural selection being the most well-known theory. However scientists also study other types of evolution such as genetic drift, mutation, and sexual selection, among other things.

Many fields of inquiry are in conflict with literal interpretations of religious texts Evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, but others haven't.
