Evolution Site - Teaching About Evolution

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

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

Definitions

It is difficult to effectively teach evolution. It is often misunderstood by non-scientists and even some scientists are guilty of using definitions that confuse the issue. This is especially relevant when it comes to the nature of the words themselves.

As such, it is essential to define 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 both an accompaniment to the 2001 series, but also a resource on its own. The material is presented in a nested fashion that assists in navigation and orientation.

The site defines terms like common ancestor, the gradual process and adaptation. These terms help frame the nature and significance of evolution to other scientific concepts. The site provides an overview of the way that evolution has been examined. This information can be used to dispel myths that have been engendered by creationists.

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

Adaptation: The tendency for hereditary traits to become more adaptable to a specific environment. This is a result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adaptable traits to survive and reproduce.

Common ancestor: The most recent common ancestor of two or 무료 에볼루션 [http://ccs-Canada.ca/?url=evolutionkr.kr] more different 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 needed for cell replication. The information is stored in nucleotide sequences, which are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

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

Origins

Species (groups which can interbreed) develop through a series natural changes in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, such as climate changes or competition for food or habitat can impede or accelerate the process.

The Evolution site traces the emergence of a variety of species of plants and animals over time with a focus on the key transitions that occurred in the history of each group. It also focuses on human evolution as a subject that is particularly important for students.

Darwin's Origin was written in 1859, at a time when only a few antediluvian fossils of humans had been found. The skullcap that is famous, along with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year before the first edition of the Origin appeared, it is highly unlikely that Darwin had seen or heard of it.

The site is primarily one of biology, but it also contains many details on geology and paleontology. The site offers several features that are especially impressive, such as a timeline of the way that climate and geological conditions have changed over the course of time. It also includes maps that show the locations of fossil groups.

While the site is a companion piece to a PBS television show, it also stands on its own as an excellent resource for teachers and students. The site is well-organized and 에볼루션 카지노 바카라 체험, simply click the up coming site, offers clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features of the museum website. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are links to John Endler's research with Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology, the study of these creatures in their geological environment offers many advantages over the current observational or experimental methods of studying evolutionary phenomena. Paleobiology can examine not only the process and events that take place frequently or over time, but also the distribution and frequency of different species of animals in space throughout geological time.

The site is divided into a variety of pathways to understanding evolution, including "Evolution 101," which takes the viewer on a line through the nature of science and the evidence to support the theory of evolution. The course also focuses on common misconceptions about evolution and the evolution of thought.

Each of the other major sections of the Evolution site is equally developed, with materials that can be used to support a range of educational levels and pedagogical styles. In addition to the general textual content, the site features an array of multimedia and interactive content including videos, animations, and virtual labs. The breadcrumb-like organization of the content aids in navigation and 에볼루션 사이트 orientation on the vast Web site.

For instance the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interaction with other organisms. Then, it zooms in on a single clam that is able to communicate with its neighbors and react to changes in water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The content also includes an explanation of the role of natural selection and the concept of phylogenetic analysis which is an important tool for understanding the evolution of change.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A wide range of resources can help teachers teach about evolution across the life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that provides the depth and breadth of its educational resources. The site has a wide array of interactive learning modules. It also features a nested "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely linked to the field of research science. An animation that introduces students to the concept of genetics, which links to a page that highlights John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.

The Evolution Library on this website has a huge multimedia library of materials that deal with evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives outlined in the standards for biology. It contains seven short videos specifically designed for use in classrooms. These can be viewed online or purchased as DVDs.

Many important questions remain in the midst of evolutionary biology, such as what triggers evolution and how fast it happens. This is especially true for human evolution, where it's been difficult to reconcile the idea that the innate physical characteristics of humans were derived from apes and religions that believe that humanity is unique among living things and holds a a special place in creation. It is soul.

Additionally there are a variety of ways that evolution can occur, with natural selection being the most popular theory. Scientists also study different types like mutation, genetic drift and sexual selection.

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