5 Evolution Site Leçons From The Professionals

Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, misconceptions persist about evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.

This site, a companion to the PBS program that provides teachers with resources that promote evolution education, while avoiding the kinds of misconceptions that can hinder it. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complex and difficult subject matter to teach well. Many non-scientists are unable to grasp the concept and some scientists use a definition which confuses it. This is especially applicable to discussions on the nature of the word.

As such, it is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, 에볼루션바카라 does this in a clear and helpful manner. The site is both an accompanying site for the 2001 series, but it is also a resource on its own. The content is presented in a way that assists in navigation and orientation.

The site defines terms like common ancestor (or common ancestor), 무료에볼루션 gradual process and adaptation. These terms help frame the nature of evolution and 바카라 에볼루션 its relationship to other concepts in science. The site then offers an overview of how the concept of evolution has been vetted and validated. This information can be used to dispel the myths that have been created by the creationists.

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

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

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

Deoxyribonucleic acid: A large biological molecule that holds the information required for cell replication. The information is contained in a sequence of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is a relation between two species in which the evolution of one species are influenced evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasites and 에볼루션 카지노 사이트 무료체험 (Elearnportal.Science) hosts.

Origins

Species (groups of individuals that are able to interbreed) develop through natural changes in the characteristics of their offspring. The causes of these changes are various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, like climate change or competition for food and habitat can impede or accelerate the process.

The Evolution site tracks through time the evolution of various species of plants and animals, focusing on major transitions in each group's past. It also examines the evolution of humans, which is a topic that is of particular interest for students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The famous skullcap, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. While the skullcap wasn't 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.

The site is primarily an online biology resource however, it also has lots of information about geology and paleontology. The website has 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 features maps that show the locations of fossil groups.

Although the site is a companion to a PBS television show however, it can stand on its own as a great resource for teachers and students. The site is well-organized and offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These links facilitate the transition from the cartoon-like 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 many species of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment is a superior method of study over the current observational or experimental methods of studying evolutionary processes. In addition to studying the processes and events that happen regularly or over a lengthy period of time, paleobiology can be used to analyze the diversity of species of organisms and their distribution across geological time.

The site is divided into several optional pathways to understanding evolution, including "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence supporting the theory of evolution. The course also focuses on misconceptions regarding evolution, as well as the history of evolutionary thinking.

Each of the main sections of the Evolution website is equally well-designed, with materials that can be used to support a variety of educational levels and teaching styles. The site offers a wide array of interactive and multimedia resources, including video clips, animations and virtual laboratories, in addition to its general textual content. The breadcrumb-like structure of the content helps with navigation and orientation on the massive Web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of the coral's relationships, their interaction with other organisms, 무료에볼루션 and then zooms in on a single clam, 무료에볼루션 which is able to communicate with its neighbours and respond to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to the broad spectrum of topics in evolutionary biology. The information also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis which is an important method to understand evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A rich collection supports teaching evolution across all disciplines of life science.

One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both depth and broadness in terms of educational resources. The site offers a variety 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 linked to the realms of research science. For example an animation that introduces the notion of genetic inheritance leads to a page highlighting 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, which includes an extensive library of multimedia assets connected to evolution. The content is organized according to curriculum-based paths that parallel the learning goals established in the biology standards. It includes seven short videos specifically designed for classroom use. These can be viewed online or purchased as DVDs.

A number of important questions remain at the core of evolutionary biology, including what triggers evolution and the speed at which it occurs. This is especially true in the case of human evolution which was a challenge to reconcile religious beliefs that held that humanity has a special place in creation and a soul with the idea that innate physical traits were derived from the apes.

In addition there are a myriad of ways that evolution can be triggered and natural selection is the most popular theory. Scientists also study different types such as mutation, genetic drift and sexual selection.

Although many scientific fields of study conflict with the literal interpretations of religious texts, evolution biology has been a source of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
