Evolution Site - Teaching About Evolution

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

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

Definitions

It's not easy to teach evolution well. Many non-scientists are unable to grasp the concept, and some scientists even employ a definition that confuses it. This is especially relevant to discussions about the definition of the word itself.

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

The site defines terms like common ancestor, gradual process, and adaptation. These terms help frame the nature of evolution as well as its relationship to other concepts in science. The website provides a summary of the manner in which evolution has been examined. This information can help dispel myths created by creationists.

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

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

Common ancestor (also known as common ancestor) is the most recent ancestor that is shared by two or more species. By analyzing the DNA from these species it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular containing the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is a relation between two species in which the evolutionary changes of one species are influenced evolutionary changes of the other. Coevolution can be seen through the interaction between predator and prey, or parasite and hosts.

Origins

Species (groups which can interbreed), evolve through a series natural changes in their offspring's traits. The changes can be caused by a variety of causes, including natural selection, genetic drift, and mixing of genes. The evolution of new species can take thousands of years. Environmental conditions, such as climate change or competition for food and habitat can slow or speed up the process.

The Evolution site tracks the development of various groups of animals and plants over time with a focus on the key transitions that occurred in the evolution of each group's history. It also examines the evolution of humans as a subject of particular importance to students.

Darwin's Origin was written in 1859, when just a few antediluvian fossils of human beings had been discovered. The skullcap that is famous, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. Although the skullcap was not published until 1858, 에볼루션 바카라사이트 just one year before the first edition of the Origin was published, it's extremely unlikely that Darwin had heard or seen of it.

While the site is focused on biology, it offers a lot of information about geology and paleontology. The most impressive features on the site are a set of timelines that illustrate the way in which climatic and geological conditions changed over time, and 에볼루션 바카라사이트 a map of the distribution of some fossil groups that are featured on the site.

While the site is a companion piece to a PBS television show but it also stands on its own as a great source for teachers and students. The site is extremely well-organized and offers clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks facilitate the move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also links to John Endler's experiments with guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology, 에볼루션 바카라사이트 the study of these creatures within their natural environment, has many advantages over modern observational or experimental methods for studying evolutionary phenomena. In addition to examining processes and events that take place regularly or over a long period of time, paleobiology allows to study the relative abundance of different kinds of organisms as well as their distribution in space over geological time.

The site is divided into a variety of ways to learn about 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 examines myths about evolution, as well as the history of evolutionary thought.

Each of the other major sections of the Evolution site is equally well developed, 에볼루션코리아 with materials that can be used to support a range of educational levels and pedagogical styles. The site includes a variety of interactive and multimedia resources which include videos, animations, and virtual labs as well as general textual content. The content is presented in a nested bread crumb-like fashion that helps with navigation and orientation within the vast Web site.

The page "Coral Reef Connections" For instance, it provides a comprehensive overview of coral relationships, their interaction with other organisms and is enlarged to show one clam that is able to communicate with its neighbors and respond to changes in conditions of the water at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a broad variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis, 에볼루션 바카라사이트 which is a crucial method to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that runs through all branches of biology. A rich collection supports teaching evolution across the disciplines of life sciences.

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web site that provides the depth and the breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also features an encased "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this massive website that are more closely linked to the field of research science. An animation that introduces students to the concept of genetics, which links to a page about John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.

Another resource that is worth mentioning is the Evolution Library on this web website, which includes an extensive collection of multimedia assets related to evolution. The content is organized according to curricula-based pathways that correspond to the learning objectives outlined in the biology standards. It includes seven short videos specifically designed for use in the classroom, 에볼루션 슬롯게임 and can be streamed at no cost or purchased on DVD.

A number of important questions remain in the midst of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is particularly true for humans' evolution, where it was difficult to reconcile religious beliefs that humanity has a unique place in the creation and a soul with the notion that our physical traits originated from Apes.

In addition, there are a number of ways in which evolution could be triggered with natural selection being the most popular theory. Scientists also study other types like mutation, genetic drift, and sexual selection.

While many scientific fields of inquiry are in conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, but others haven't.
