Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions about evolution. Pop science fiction has led a lot of people to believe that biologists aren't believers in evolution.

This rich Web site - companion to the PBS series It provides teachers with materials which support evolution education and avoids the kinds of myths that hinder it. It's laid out in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complex and 에볼루션 바카라 무료체험 difficult subject to teach well. It is often misunderstood even by non-scientists, and 에볼루션 바카라 무료 even some scientists use an interpretation that is confusing the issue. This is especially relevant to discussions about the definition of the word itself.

It is therefore essential to define the terms used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient way. The site serves as a companion for the 2001 series, but also a resource on its own. The information is presented in a structured manner that makes it easier to navigate and understand.

The site defines terms such as common ancestor and the gradual process. These terms help to define the nature and relationship of evolution to other scientific concepts. The site provides an overview of the way the concept of evolution has been tested. This information can help dispel myths that are created by the creationists.

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

The process of adaptation is the tendency of hereditary traits to become better suited to an environment. This is the result of natural selection, which happens when organisms that have better adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.

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

Deoxyribonucleic Acid: A large biological molecular that holds the necessary information for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, referred to as chromosomes. Mutations are the source of new genetic information in cells.

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

Origins

Species (groups that can interbreed), evolve through a series natural changes in their offspring's traits. These changes are caused by a variety of factors, including natural selection, genetic drift and gene pool mixing. The evolution of new species can take thousands of years. Environmental conditions, like climate changes or competition for food or 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 shifts that occurred throughout the evolution of each group's history. It also focuses on human evolution as a subject that is of particular interest for students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known 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 extremely unlikely that Darwin had ever heard of it.

The site is mostly a biology site however, 무료에볼루션 it also has many details on geology and paleontology. The most impressive features on the site are a timeline of events which show how geological and climatic conditions have changed over time, and an interactive map of the distribution of some fossil groups listed on the site.

The site is a companion for a PBS television series, but it could also be used as a source for teachers and students. The site is well-organized and 에볼루션코리아 (Www.Daoban.org) provides 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's website. 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 links to John Endler's experiments with guppies that illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life has resulted in an array of plants, animals and insects. Paleobiology is the study of these creatures in their natural environment offers many advantages over the current observational or experimental methods for exploring evolutionary processes. In addition to exploring the processes and events that happen regularly or over a long period of time, paleobiology can be used to analyze the diversity of groups of organisms and their distribution throughout geological time.

The Web site is divided into a variety of paths to learning evolution, including "Evolution 101," which takes the viewer on a line through the scientific process and the evidence that supports the theory of evolution. The course also focuses on common misconceptions about evolution as well as the evolution of thought.

Each of the other sections of the Evolution site is equally well created, with resources that can be used to support a range of educational levels and pedagogical styles. The site includes a variety of multimedia and interactive resources which include video clips, animations 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.

The page "Coral Reef Connections" For instance, it provides a comprehensive overview of the coral's relationships and interactions with other organisms, and 에볼루션 바카라 무료체험 then is enlarged to show one clam that is able to communicate with its neighbors and react to changes in the water conditions that occur on the reef level. 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 a discussion on the significance of natural selectivity and the concept of phylogenetics analysis which is a crucial method for understanding the evolution of 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 series Understanding Evolution is an excellent example of an Web site that provides the depth and the wide range of educational resources. The site offers a range of interactive learning modules. It also features an "bread crumb structure" that allows students to move away from the cartoon-like style of Understanding Evolution and onto elements on this large website more closely related to the realms of research science. Animation that introduces the concept of genetics is linked 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 is a vast multimedia library of materials that deal with evolution. The content is organized in curricula-based paths that correspond to the learning objectives outlined in the biology standards. It contains seven videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.

Evolutionary biology is a field of study that has many important questions, such as what triggers evolution and the speed at which it takes place. This is particularly relevant in the case of human evolution where it was a challenge to reconcile religious beliefs that humans have a distinct position in the universe and a soul, with the notion that our physical traits were derived from apes.

There are a myriad of other ways in which evolution could occur, with natural selection as the most widely accepted theory. Scientists also study other kinds such as genetic drift and sexual selection.

While many scientific fields of inquiry have a conflict with the literal interpretations of religious texts, evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution but others haven't.
