Evolution Site - Teaching About Evolution

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

This rich Web site, which is a companion to the PBS program that provides teachers with resources that promote evolution education, while avoiding the kinds of misconceptions which undermine it. It's laid out in a nested "bread crumb" format to make it easy for 바카라 에볼루션 (m.414500.cc) navigation and orientation.

Definitions

Evolution is a complicated and difficult subject matter to teach well. It is often misunderstood by non-scientists, and even some scientists have been guilty of using definitions that confuse the issue. This is particularly applicable to discussions on the meaning of the word itself.

Therefore, 에볼루션바카라 it is important to define terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient way. The site serves as a companion for the 2001 series, and it is also a resource on its own. The material is presented in a way that assists in navigation and orientation.

The site defines terms like common ancestor (or common ancestor), gradual process and adaptation. These terms help define the nature and 바카라 에볼루션 significance of evolution with other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and confirmed. This information can help dispel myths that are created by the creationists.

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

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

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

Deoxyribonucleic Acid: A huge biological molecular that contains the information needed for cell replication. The information is contained in a sequence of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution: A relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups of individuals that can interbreed) develop through natural changes in the traits of their offspring. These changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The development of a new species can take thousands of years, and the process can be slowed down or speeded up by environmental conditions such as climate change or the competition for food or habitat.

The Evolution site follows the evolution of various animal and plant groups, focusing on major transitions within each group's past. It also explores human evolution as a subject of particular importance for students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, one year following the initial edition of The Origin.

The site is primarily one of biology, but it also contains many details on paleontology and geology. The most impressive features on the site are a set of timelines that show how climatic and geological conditions have changed over time as well as an interactive map of the distribution of some fossil groups that are featured on the site.

The site is a companion for a PBS TV series but it could also be used as a resource by 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 sophisticated elements of the museum's web site. 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 of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of animals, plants, and insects. Paleobiology, the study of these creatures in their geological context offers many advantages over modern observational or research methods for studying evolutionary phenomena. In addition to studying processes and events that occur regularly or over a long period of time, 에볼루션 블랙잭카지노 [www.Bitsdujour.com] paleobiology is able to study the diversity of kinds of organisms as well as their distribution throughout 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 scientific process and the evidence supporting the theory of evolution. The path also explores misconceptions about evolution, and also the history of evolutionary thought.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that can be used to support a variety of educational levels and teaching styles. The site includes a variety of multimedia and interactive resources, including animations, video clips and virtual labs, in addition to its general textual content. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the large web site.

For instance, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms. It then concentrates on a specific clam that is able to communicate with its neighbours and respond to changes in the water conditions at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages, offers a great introduction to the many areas of evolutionary biology. The content includes an overview of the importance of natural selection and the concept phylogenetics analysis, an important tool 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 life science disciplines.

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that provides depth and broadness in terms of educational resources. The site offers a range of interactive learning modules. It also features an "bread crumb structure" that assists students in moving away from the cartoon style that is used in Understanding Evolution and onto elements on this site that are more closely connected to the worlds of research science. For instance, an animation introducing the idea of genetic inheritance connects to a page that highlights John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

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

Many important questions remain at the heart of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is particularly true for humans' evolution which was a challenge to reconcile religious beliefs that humanity has a special place in creation and a soul with the idea that innate physical traits were derived from Apes.

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

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