Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation 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 offers teachers with resources which support evolution education and help avoid the kinds of myths that hinder it. It's organized in a "bread crumb" format to make navigation and orientation easier.

Definitions

It is difficult to properly teach evolution. It is often misunderstood by non-scientists, and even scientists are guilty of using definitions that confuse the issue. This is particularly true when it comes to discussions about the nature of the word.

It is essential to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site is a companion site to the show which first aired in 2001, but it also functions as an independent resource. The material is presented in a structured manner that makes it easier to navigate and understand.

The site defines terms like common ancestor, gradual process and 에볼루션 사이트 so on. These terms help define the nature and relationship of evolution to other concepts in science. The site provides an overview of the manner that evolution has been tested. This information can be used to dispel misconceptions that have been created by creationists.

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

Adaptation is the process of changing hereditary traits to become more suited to the environment. This is due to natural selection. It occurs when organisms that have 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 different species. By studying the DNA of these species it is possible to identify the common ancestor.

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

Coevolution: A relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or the parasite and the host.

Origins

Species (groups that can interbreed) develop through a series of natural changes in the traits of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift, 에볼루션 사이트 and mixing of the gene pool. The evolution of a new species can take thousands of years and the process could be slowed or increased by environmental factors like climate change or the competition for food or habitat.

The Evolution site tracks the development of a number of different groups of animals and plants over time and focuses on the most significant shifts that occurred throughout the history of each group. It also explores human evolution as a subject that is particularly important for students.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. 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. Although the skullcap was not published until 1858, a year before the first edition of the Origin was published, it is highly unlikely that Darwin had heard or seen of it.

While the site focuses on biology, it includes a good deal of information about geology as well as paleontology. One of the most appealing features of the Web site are a set of timelines that show the way in which climatic and geological conditions have changed over time, as well as 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 series but it also stands on its own as an excellent source for teachers and students. The site is well-organized and provides easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features of the museum website. These hyperlinks help users move 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 has produced many species of animals, plants and 에볼루션 바카라 무료체험 insects. Paleobiology, the study of these creatures in their geological environment offers many advantages over modern observational or experimental methods for studying evolutionary processes. In addition to studying processes and events that take place frequently or over a long period of time, paleobiology is able to study the diversity of species of organisms and their distribution across geological time.

The website is divided into several optional paths to learning evolution that include "Evolution 101," which takes the user on a linear path through the scientific process and the evidence supporting the theory of evolution. The path also reveals common misconceptions about evolution and the evolution of thought.

Each of the other major sections of the Evolution site is similarly created, with resources that can be used to support a range of curriculum levels and pedagogical styles. In addition to the standard textual content, the site features an array of multimedia and interactive resources, such as videos, animations and virtual laboratories. The breadcrumb-like structure of the content assists with navigation and orientation on the vast 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 zooms in to a single clam, which is able to communicate with its neighbors and react to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, 에볼루션 슬롯 gives a good introduction to the many areas of evolutionary biology. The content also includes an overview of the significance of natural selectivity and 에볼루션 바카라 사이트 the concept of phylogenetics as a key method for understanding the evolution of changes.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A vast collection of books helps in teaching evolution across all life science disciplines.

One resource, 에볼루션 사이트 which is a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that offers both depth and breadth in its educational resources. The site has a wide array of interactive learning modules. It also features a "bread crumb structure" that assists students in moving away from the cartoon style of Understanding Evolution and onto elements of this vast website that are closely related to the realms of research science. For example an animation that explains the concept of genetic inheritance links to a page highlighting John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of materials that deal to evolution. The content is organized according to courses that are based on curriculum and follow the learning goals established in biology standards. It contains seven short videos specifically designed for use in classrooms. They are available to stream or purchase as DVDs.

Evolutionary biology remains a field of study that has many important questions, such as the causes of evolution and how quickly it occurs. This is especially true in the case of human evolution where it was a challenge to reconcile religious beliefs that humanity has a unique position in the universe and a soul, with the idea that innate physical traits were derived from Apes.

There are a myriad of other ways evolution can occur and natural selection being the most popular theory. However scientists also study different kinds of evolution like mutation, genetic drift, and sexual selection, among other things.

While many scientific fields of inquiry conflict with literal interpretations of religious texts, evolutionary biology has been the subject of particularly intense controversy and 무료 에볼루션 resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
