Evolution Site - Teaching About Evolution

Despite the best efforts by biology teachers, there are still misconceptions regarding evolution. People who have absorbed the nonsense of pop science often believe that biologists are saying they don't believe in evolution.

This site, which is a complement to the PBS program offers teachers resources that support the evolution of education while avoiding the types of misconceptions that make it difficult to understand. It's laid out in the "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to properly teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. This is particularly relevant when it comes to the meaning of the words themselves.

It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful manner. The website is a companion to the series that first aired in 2001, but it is also an independent resource. The content is presented in a way which aids navigation and orientation.

The site defines terms such as common ancestor and the gradual process. These terms help frame the nature of evolution and its relationship to evolution to other concepts in science. The website provides a summary of the way that evolution has been examined. This information can be used to dispel the myths that have been created by the creationists.

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

Adaptation: 에볼루션 슬롯 The tendency for heritable traits to become better adaptable to a specific environment. This is a result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adaptable traits to reproduce and survive.

Common ancestor (also known as common ancestor): The most recent ancestral ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of these species.

Deoxyribonucleic Acid: A huge biological molecular that contains the necessary information for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution is evident in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups which can interbreed), 에볼루션 룰렛 evolve by a series of natural variations in the traits of their offspring. The causes of these changes are many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental circumstances, such as climate change or competition for food resources and habitat, can slow or accelerate the process.

The Evolution site tracks through time the evolution of different animal and plant groups with a focus on major changes in each group's past. It also examines the evolutionary origin of humans and humans, a subject that is especially important for students to understand.

Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans were discovered. The famous skullcap, with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized 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 ever heard of it.

The site is primarily one of biology, but it also contains lots of information about paleontology and geology. The most impressive features of the website are a timeline of events that illustrate how geological and climatic conditions have changed over time as well as an interactive map of the geographical 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 between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized components of the museum's Web site. These links facilitate the transition from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular, there are links to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of animals, plants and insects. Paleobiology is the study of these creatures within their natural environment and has numerous advantages over modern observational and experimental methods for analyzing evolutionary processes. Paleobiology is able to study not only processes and events that happen regularly or over time but also the relative abundance and distribution of different species of animals in space over the course of the geological time.

The site is divided up into several options to gain knowledge about evolution. One of these paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also reveals common misconceptions about evolution and the history of evolutionary thought.

Each of the other sections of the Evolution site is similarly constructed, with materials that can support a variety of educational levels and pedagogical styles. In addition to the standard textual content, the site also has a wide range of interactive and multimedia resources including video clips, animations, and virtual labs. The content is presented in a nested bread crumb-like fashion that helps with navigation and orientation within the large Web site.

The page "Coral Reef Connections" For 에볼루션코리아 instance, it gives a brief overview of coral relationships, their interaction with other organisms, and then zooms in on a single clam, which is able to communicate with its neighbours and 에볼루션 코리아 respond to changes in the conditions of the water at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a wide variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is a key method to understand evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A vast collection of books helps in teaching evolution across the disciplines of life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides the depth and breadth of its educational resources. The site features a wide range of interactive learning modules. It also features a "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. An animation that introduces the concept of genetics is linked to a page highlighting John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.

The Evolution Library on this website is a vast multimedia library of assets related with evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives outlined in the standards for biology. It contains seven videos designed specifically for use in the classroom, and can be streamed for no cost or purchased on DVD.

Many important questions remain at the core of evolutionary biology, including what triggers evolution and how fast it happens. This is particularly relevant for the evolution of humans, where it was difficult to reconcile religious beliefs that held that humanity has a unique place in the creation and a soul with the idea that innate physical traits were derived from the apes.

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

Although many scientific fields of study conflict with literal interpretations found in religious texts, evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, other religions aren't.
