Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions persist about evolution. People who have taken in popular science myths often assume that biologists do not believe in 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 types of misconceptions which undermine it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to effectively teach evolution. It is often misunderstood even by non-scientists, and even some scientists have been guilty of using definitions that confuse the issue. This is especially relevant when discussing the meaning of the words themselves.

As such, it is essential to define terms used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient manner. The website is a companion to the show that premiered in 2001, 에볼루션 but is also an independent resource. The material is presented in a nested fashion that aids navigation and orientation.

The site defines terms like common ancestor (or common ancestor), gradual process, and adaptation. These terms help to define the nature of evolution and 무료에볼루션 무료체험 (Morphomics.Science) its relationship to evolution with other scientific concepts. The website provides a summary of the ways in which evolution has been examined. This information can help dispel myths created by creationists.

It is also possible to get the glossary of terms used in evolutionary biology. These terms include:

Adaptation: The tendency of heritable characteristics to become more suited to a particular environment. This is the result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adapted characteristics to survive and reproduce.

Common ancestor (also known as common ancestor) is the most recent ancestral ancestor 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 molecule that contains information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains 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 influenced by evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or parasite and host.

Origins

Species (groups which can interbreed) change through a series natural changes in their offspring's traits. The causes of these changes are various factors, including natural selection, gene drift, and mixing of the gene pool. The evolution of a new species may take thousands of years and the process could be slowed down or speeded up by environmental factors like climate change or the competition for food or habitat.

The Evolution site traces through time the evolution of various species of plants and animals with a focus on major changes within each group's past. It also examines the evolution of humans and is a subject that is particularly important for students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The skullcap that is famous, along with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was first published in 1858, which was a year following the initial edition of The Origin.

While the site focuses on biology, it also includes a good deal of information about geology and paleontology. The most impressive features of the Web site are a timeline of events that illustrate how climatic and geological conditions changed over time, and an outline of the distribution of a few fossil groups that are featured on the site.

The site is a companion to a PBS television series, but it could also be used as a resource for teachers and students. The site is well-organized, and provides clear 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. Particularly there are hyperlinks to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of animals, plants and insects. Paleobiology is the study of these creatures within their geological context, has many advantages over the current observational or experimental methods for studying evolutionary phenomena. In addition to examining the processes and events that happen regularly or over a long period of time, paleobiology can be used to analyze the relative abundance of different kinds of organisms as well as their distribution across geological time.

The website is divided into several options to gain knowledge about evolution. One of these paths, "Evolution 101," guides the user through the nature and evidence of evolution. The path also explores misconceptions about evolution, and also the history of evolutionary thinking.

Each of the other sections of the Evolution site is equally constructed, with materials that support a variety of educational levels and pedagogical styles. The site has a range of multimedia and interactive resources that include videos, animations, and virtual labs as well as general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the massive website.

The page "Coral Reef Connections", for example, gives a brief overview of the relationships between corals and interactions with other organisms and zooms in on one clam that is able to communicate with its neighbors and 에볼루션 코리아 respond to changes in water conditions that occur on 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 as a key tool to understand evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that connects all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and breadth in its educational resources. The site features a wealth of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the field of research science. For instance an animation that introduces the idea of genetic inheritance connects to a page that highlights John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

Another helpful resource is the Evolution Library on this web website, 에볼루션 which includes an extensive multimedia library of assets connected to evolution. The content is organized according to curriculum-based pathways that correspond to the learning goals set forth in the standards for biology. It includes seven short videos specifically designed for use in the classroom, and can be streamed for no cost or purchased on DVD.

Many important questions remain at the core of evolutionary biology, such as the factors that trigger evolution and how fast it occurs. 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 claim that humans are unique among living things and holds a an exclusive place in the creation. It is a soul.

There are also a number of other ways evolution can occur including natural selection, which is the most widely accepted theory. However, scientists also study other types of evolution such as mutation, genetic drift and sexual selection, among others.

Although many scientific fields of study conflict with literal interpretations found in religious texts, the concept of evolution biology has been the subject of intense debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
