Why All The Fuss Over Evolution Site?

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions persist about the evolution. People who have been exposed to popular science myths often assume that biologists claim they don't believe in evolution.

This rich Web site, which is a complement to the PBS program offers teachers resources that promote evolution education while avoiding the types of misconceptions which undermine it. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

Evolution is a complex and difficult subject to teach effectively. It is often misunderstood by non-scientists and even scientists are guilty of using an interpretation that is confusing the issue. This is particularly relevant to discussions about the definition of the word itself.

Therefore, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. It is an accompanying site for the 2001 series, but also a resource of its own. The material is presented in a structured manner that makes it simpler to navigate and 무료에볼루션 understand.

The site defines terms like common ancestor (or common ancestor), gradual process and adaptation. These terms help frame the nature of evolution and its relationship to other scientific concepts. The website provides a summary of the ways that evolution has been tested. This information can help dispel the myths created by creationists.

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

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

Common ancestor: The latest common ancestor of two or more distinct 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 stored in a sequence of nucleotides that are strung together to form long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is a relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution are the interactions between predator 에볼루션 바카라 and prey, or the parasite and the host.

Origins

Species (groups that can interbreed) change through a series natural changes in their offspring's traits. These changes are caused by a variety, including natural selection, genetic drift, and mixing of genes. The evolution of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food or habitat can slow or speed up the process.

The Evolution site traces through time the evolution of different animal and plant groups and focuses on major changes in each group's history. It also explores the human evolutionary roots, a topic that is particularly important for students to understand.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year after the first edition of the Origin appeared, 에볼루션 무료체험 룰렛 (have a peek here) it is very unlikely that Darwin had ever heard of it.

While the site is focused on biology, it also includes a good deal of information about geology as well as paleontology. Among the best features on the site are a timeline of events that show how geological and climatic conditions have changed over time, as well as an outline of the distribution of a few fossil groups listed on the site.

While the site is a companion to the PBS television show however, it can stand on its own as a great source for teachers and students. The site is well organized and provides clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized components of the museum's Web site. These hyperlinks make it easy to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular, there are links to John Endler's research with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants, and 에볼루션바카라 insects. Paleobiology is the study of these creatures within their geological context is a superior method of study over modern observational or experimental methods of studying evolutionary processes. Paleobiology can examine not just the processes and events that take place regularly or over time, but also the distribution and frequency of different groups of animals in space throughout the geological time.

The site is divided up into various paths that can be chosen to study the subject of evolution. One of the paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The path also examines myths about evolution and the background of evolutionary thought.

Each of the other main sections of the Evolution site is equally well constructed, with materials that can be used to support a range of educational levels and pedagogical styles. In addition to the general textual content, the site offers a wide range of multimedia and interactive resources like video clips, animations, and virtual labs. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation on the web site.

For instance, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms. It then zooms in on a single clam that is able to communicate with its neighbours and respond to changes in water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to a variety 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 connects all branches of biology. A vast collection of books helps in teaching evolution across all life science disciplines.

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth and broadness in terms of educational resources. The site has a variety of interactive learning modules. It also features a nested "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. Animation that introduces the concept of genetics is linked to a page about John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.

Another useful resource is the Evolution Library on this website, which includes an extensive collection of multimedia resources that are related to evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives outlined in the standards for biology. It contains seven videos specifically intended for use in the classroom. They can be streamed or purchased as DVDs.

Evolutionary biology is still an area of study that poses many important questions to answer, such as what triggers evolution and the speed at which it takes place. This is especially true for humans' evolution which was a challenge to reconcile religious beliefs that held that humanity has a special position in the universe and a soul, with the notion that human beings have innate physical traits originated from apes.

There are a myriad of other ways evolution could occur and natural selection being the most widely accepted theory. Scientists also study different types like mutation, genetic drift and sexual selection.

Many fields of inquiry conflict with literal interpretations of religious texts evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the theories of evolution, others aren't.
