Evolution Site - Teaching About Evolution

Despite the best efforts by biology teachers, there are still misconceptions regarding evolution. People who have taken in popular science myths often assume that biologists are saying they do not believe in evolution.

This site, which is a companion to the PBS series - provides teachers with materials which support evolution education and help avoid the kinds of misinformation that can undermine it. It's organized in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It's not easy to properly teach evolution. It is often misunderstood by non-scientists, and even some scientists use an interpretation that is confusing the issue. This is particularly relevant when discussing the definition of the words.

Therefore, it is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, 에볼루션 does this in a simple and efficient manner. The site is a companion site to the series that first aired in 2001, but is also an independent resource. The material is organized in a way that makes it easy to navigate and 에볼루션 바카라 무료체험 understand.

The site defines terms like common ancestor, gradual process and so on. These terms help to define the nature and significance of evolution to other concepts in science. The site gives a comprehensive overview of the ways the concept of evolution has been tested. This information can be used to dispel misconceptions that have been propagated by the creationists.

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

Adaptation is the tendency of heritable traits to be more suitable to their environment. This is a result of natural selection, which happens when organisms that have better-adapted traits are more likely to survive and reproduce than those with less adaptable traits.

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 molecule that contains the information needed for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

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

Origins

Species (groups that can interbreed) develop through a series of natural changes in the traits of their offspring. The changes can be triggered by a variety, including natural selection, genetic drift and mixing of genes. The development of a new species could take thousands of years, and the process could be slowed down or 에볼루션 바카라사이트 speeded up by environmental factors like climate change or the competition for food or habitat.

The Evolution site tracks the development of various animal and plant groups through time, focusing on the major shifts that occurred throughout the history of each group. It also focuses on human evolution, which is a topic that is of particular interest to students.

Darwin's Origin was written in 1859, when only a few antediluvian fossils of humans had been found. Among them was the famous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, 에볼루션 무료 바카라 which was a year before the first edition of the Origin was published, it is extremely unlikely that Darwin had heard or seen of it.

The site is mostly one of biology however it also includes a lot of information on paleontology and geology. Among the best features of the Web site are a series of timelines that show the way in which climatic and geological conditions changed over time, as well as a map of the distribution of some fossil groups listed on the site.

Although the site is a companion piece to a PBS television series however, it can stand on its own as a valuable source for teachers and students. The site is very well-organized and offers clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. These hyperlinks make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly 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 led to a wide variety of animals, plants and insects. Paleobiology is the study of these creatures in their geological environment is a superior method of study over modern observational or experimental methods for studying evolutionary processes. In addition to studying processes and events that take place regularly or over a lengthy period of time, paleobiology is able to study the relative abundance of various species of organisms and 에볼루션 무료체험 their distribution across geological time.

The website is divided into various routes that can be taken to gain knowledge about evolution. One of these paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought.

Each of the other main sections of the Evolution site is equally created, with resources that can be used to support a range of educational levels and pedagogical styles. In addition to general textual content, the site also has an array of interactive and multimedia resources like videos, animations, and virtual laboratories. The breadcrumb-like arrangement of the content assists with navigation and orientation on the large Web site.

For example, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms, then concentrates on a specific clam that can communicate with its neighbors and react to changes in water conditions that take place 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 broad spectrum of topics in evolutionary biology. The content also includes a discussion of the role of natural selection and the concept of phylogenetic analysis which is a crucial method to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that runs through all branches of biology. A wide range of resources supports teaching about evolution across all life sciences.

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that offers both the depth and the breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also features an "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 worlds of research science. An animation that introduces students to the concept of genetics is linked to a page about John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning objectives outlined in biology standards. It includes seven short videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD.

A number of important questions remain in the midst of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is particularly relevant for humans' evolution which was a challenge to reconcile religious beliefs that held that humanity has a unique position in the universe and a soul, with the notion that human beings have innate physical traits were derived from the apes.

In addition, there are a number of ways in which evolution could be triggered with natural selection being the most popular theory. However scientists also study different types of evolution such as mutation, genetic drift, and sexual selection, among others.

While many scientific fields of inquiry have a conflict with literal interpretations of religious texts, evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, other religions haven't.
