What Is Evolution Site And Why Is Everyone Speakin About It

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science fiction has led a lot of people to believe that biologists don't believe 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 kinds of misconceptions that make it difficult to understand. It's laid out in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It's not easy to properly teach evolution. It is often misunderstood by non-scientists, and even some scientists are guilty of using an interpretation that is confusing the issue. This is especially true when discussing the definition of the words.

It is therefore crucial 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 both an accompaniment to the 2001 series, and also a resource of its own. The content is presented in a way which aids navigation and orientation.

The site defines terms like common ancestor, the gradual process, and adaptation. These terms help to frame the nature of evolution as well as its relation to other concepts in science. 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 find a glossary of terms that are 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, which occurs when organisms with better adapted traits are more likely to survive and reproduce than those with less adaptable characteristics.

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

Deoxyribonucleic Acid: A massive biological molecular containing the necessary information for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

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

Origins

Species (groups of individuals who can interbreed) develop through a series of natural changes in the characteristics of their offspring. The changes can be caused by a variety of factors, including natural selection, genetic drift and mixing of genes. The evolution of a new species may take thousands of years and the process may be slowed down or accelerated due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site tracks the evolution of a variety of groups of animals and plants over time with a focus on the key transitions that occurred in each group's history. It also examines the evolutionary history of humans which is crucial for students to comprehend.

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

While the site is focused on biology, it offers a lot of information on geology and paleontology. Among the best features of the Web site are a timeline of events that show how climatic and geological conditions have changed over time, and an interactive map of the distribution of some fossil groups that are featured on the site.

Although the site is a companion to a PBS television show however, it can stand on its own as an excellent source for teachers and students. The site is well-organized and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features of the museum website. These links make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. In particular there are links to John Endler's experiments using Guppies, which demonstrate the importance of 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 in their natural environment and has many advantages over the current observational and experimental methods in its exploration of evolutionary phenomena. Paleobiology focuses on not only processes and events that happen frequently or over time, but also the distribution and frequency of different groups of animals in space over the course of geological time.

The website is divided into different paths that can be chosen to learn about evolution. One of these paths, "Evolution 101," guides the user through the evolution of nature and the evidence of evolution. The path also reveals common misconceptions about evolution and the evolution of thought.

Each of the main sections on the Evolution website is equally well-developed, and includes materials that support a variety educational levels and teaching styles. The site includes a variety of interactive and multimedia resources that include animations, video clips and virtual laboratories as well as general textual content. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the large Web site.

For instance, the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interactions with other organisms. It then concentrates on a specific clam that is able to communicate with its neighbors and react to changes in water conditions that occur at the level of the reef. This page, along with the other multidisciplinary interactive and multimedia pages gives a good introduction to many topics in evolutionary biology. The material includes an explanation of the importance of natural selection and the concept phylogenetics analysis as a key tool for understanding evolutionary change.

Evolutionary Theory

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

One resource, 에볼루션 블랙잭 the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth and wide range of educational resources. The site features a wealth of interactive learning modules. It also features a "bread crumb structure" that assists students in moving 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 that introduces the notion of genetic inheritance leads to a page that focuses on John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad.

Another useful resource is the Evolution Library on this web site, which contains an extensive library of multimedia resources connected to evolution. The content is organized into curriculum-based paths that parallel the learning objectives set out in the biology standards. It includes seven short videos designed specifically for use in classrooms, and can be streamed for no cost or purchased on DVD.

A variety of crucial questions remain in the midst of evolutionary biology, such as the factors that trigger evolution and how fast it occurs. This is particularly applicable to human evolution where it has been difficult to reconcile that the physical traits 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 with a soul.

There are a variety of other ways in which evolution could occur, with natural selection as the most widely accepted theory. However scientists also study different kinds of evolution like genetic drift, mutation, and 에볼루션 바카라 무료체험게이밍 - our website, sexual selection, among others.

Many fields of inquiry conflict with literal interpretations of religious texts evolutionary biology has been the subject of fierce debate and 에볼루션바카라사이트 (www.tpdl.co.nz) opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
