Evolution Site - Teaching About Evolution

Despite the best efforts by biology teachers, there are still misconceptions about the evolution. Pop science nonsense has led many people to believe that biologists don't believe evolution.

This rich Web site, which is a companion to the PBS program offers teachers resources which support evolution education, while avoiding the kinds of misconceptions that hinder it. It's laid out in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It is difficult to teach evolution well. Non-scientists often misunderstand 에볼루션 바카라 the subject and some scientists use a definition which confuses it. This is particularly relevant when it comes to the definition of the words.

It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site is a companion to the show which first aired in 2001, but it also functions as an independent resource. The material is presented in an organized manner that makes it easier to navigate and comprehend.

The site defines terms such as common ancestor, gradual process and adaptation. These terms help to frame the nature of evolution as well as its relationship to other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and verified. This information can be used to dispel misconceptions that have been propagated by creationists.

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

Adaptation: The tendency of heritable characteristics to become more suitable to a particular setting. This is the result of natural selection. It occurs when organisms with more adaptable traits are more likely to survive and reproduce than those with less adapted characteristics.

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 molecular that holds the information needed for 에볼루션 게이밍 (K12.Instructure.Com) cell replication. The information is stored in nucleotide sequences, which are strung into long chains, referred to as chromosomes. Mutations are the basis for 무료 에볼루션 new genetic information in cells.

Coevolution is a relation between two species, where the evolutionary changes of one species are influenced evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or parasite and host.

Origins

Species (groups that can crossbreed) develop through a series natural changes in their offspring's traits. These 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 slow or accelerate the process.

The Evolution site follows the evolution of different animal and plant groups with a focus on major changes within each group's past. It also explores human evolution, which is a topic that is of particular interest to students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. The famous skullcap, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was one year after the first edition of the Origin was published, it is extremely unlikely that Darwin had ever heard of it.

The site is primarily a biology site, but it also contains many details on paleontology and geology. The website has numerous features that are especially impressive, such as the timeline of how geological and climate conditions have changed over time. It also includes an interactive map that shows the location of fossil groups.

While the site is a companion to a PBS television series however, it can stand on its own as a valuable resource for teachers and students. The site is extremely well-organized and offers clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler’s experiments with guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to many species of animals, plants and insects. Paleobiology, the study of these creatures in their geological context offers many advantages over modern observational or research methods of studying evolutionary processes. In addition to exploring processes and events that occur regularly or over a lengthy period of time, paleobiology can be used to study the diversity of groups of organisms and their distribution across the geological time.

The Web site is divided into various paths to learning 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 misconceptions regarding evolution, and also the history of evolutionary thought.

Each of the other main sections of the Evolution site is equally developed, with materials that can be used to support a range of curriculum levels and pedagogical styles. In addition to the standard textual content, the site offers an extensive selection of interactive and multimedia resources including videos, animations, and virtual laboratories. The breadcrumb-like structure of the content assists with navigation and orientation on the massive website.

The page "Coral Reef Connections" For instance, it provides a comprehensive overview of coral relationships, their interaction with other organisms and zooms in on a single clam, 에볼루션 바카라 체험 which can communicate with its neighbors and 에볼루션 respond to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and 에볼루션 룰렛 multimedia pages, provides an excellent introduction to the many areas of 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 tool in understanding evolutionary changes.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A vast collection of resources helps teachers teach about evolution across all life sciences.

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of an Web site that provides depth as well as breadth in terms of its educational resources. The site features a wealth 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 huge site that are more closely linked to the world of research science. An animation that introduces the concept of genetics links to a page highlighting John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.

Another helpful resource is the Evolution Library on this web website, which includes an extensive library of multimedia assets that are related to evolution. The contents are organized into curriculum-based paths that parallel the learning objectives outlined in biology standards. It contains seven videos designed for classroom use. These are available to stream or purchase as DVDs.

Many important questions remain at the core of evolutionary biology, including what causes evolution to occur and the speed at which it occurs. This is particularly relevant for the evolution of humans, where it was difficult to reconcile religious beliefs that held that humans have a distinct place in the creation and a soul with the idea that innate physical traits originated from apes.

Additionally there are a myriad of ways that evolution can occur, with natural selection being the most widely accepted theory. However scientists also study different kinds of evolution, 에볼루션 such as mutation, genetic drift, and sexual selection, among others.

Many fields of inquiry are in conflict with the literal interpretations of the Bible evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the theories of evolution, other religions haven't.
