Evolution Site - Teaching About Evolution

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

This rich Web site, which is a complement to the PBS program, provides teachers with materials that promote evolution education while avoiding the types of misconceptions that make it difficult to understand. It's organized in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complex and difficult subject to teach well. It is often misunderstood by non-scientists, and even some scientists use definitions that confuse the issue. This is particularly relevant to debates about the meaning of the word itself.

It is therefore crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The website is a companion to the series that first aired in 2001, but it can also function as an independent resource. The material is presented in a way that aids navigation and orientation.

The site defines terms like common ancestor and the gradual process. These terms help to define the nature of evolution as well as its relationship to other scientific concepts. The website then provides an overview of how the concept of evolution has been vetted and verified. This information can be used to dispel misconceptions that have been engendered by creationists.

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

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

Common ancestor (also called common ancestor) The most recent ancestor shared by two or 무료 에볼루션 more species. By analyzing DNA from these species it is possible to determine the common ancestor.

Deoxyribonucleic acid: A massive biological molecule that contains information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are the cause of new genetic information in cells.

Coevolution is a relation between two species where evolutionary changes of one species are influenced evolutionary changes of the other. Coevolution is evident in the interactions between predator and prey, or parasites and hosts.

Origins

Species (groups that can interbreed) change through a series of natural changes in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift, 에볼루션 바카라 무료 (link home) and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, like climate changes or competition for food resources and habitat can impede or accelerate the process.

The Evolution site tracks the evolution of a variety of groups of animals and plants over time with a focus on the key shifts that occurred throughout the history of each group. It also focuses on human evolution and is a subject that is particularly important to students.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The skullcap that is famous, along with the bones associated with it, 에볼루션카지노 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 before the first edition of the Origin was published, it's highly unlikely that Darwin had ever heard of it.

The site is mostly a biology site however it also includes a lot of information on geology and paleontology. The most impressive features on the site are a set of timelines that illustrate the way in which climatic and geological conditions have changed over time, and an interactive map of the geographical distribution of some of the fossil groups featured on the site.

While the site is a companion to the PBS television show but it also stands on its own as a great resource for teachers and students. The site is very well organized and provides clear links between the introduction 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 facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world 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 led to a wide variety of animals, plants and insects. Paleobiology is the study of these creatures within their natural environment and has a number of advantages over the current observational and experimental methods of examining evolutionary phenomena. In addition to examining processes and events that take place regularly or over a lengthy period of time, paleobiology allows to study the relative abundance of various species of organisms and their distribution throughout the geological time.

The site is divided up into various paths that can be chosen to learn about evolution. One of these paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The path also explores misconceptions regarding 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 support a variety educational levels and teaching styles. In addition to general textual content, the site features an extensive selection of multimedia and interactive content including video clips, animations, and virtual labs. The breadcrumb-like structure of the content helps with navigation and orientation on the large web site.

For example, the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interaction with other organisms, then concentrates on a specific clam that can communicate with its neighbors and react to changes in water conditions at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a wide range of topics in evolutionary biology. The content includes a discussion on the importance of natural selection and the concept phylogenetics analysis as a key tool to understand evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A rich collection of resources can help teachers teach about evolution across the life sciences.

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that offers both depth and wide range of educational resources. The site has a variety of interactive learning modules. It also has an encased "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the field of research science. For example an animation that introduces the concept of genetic inheritance links to a page that highlights John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad.

Another resource that is worth mentioning is the Evolution Library on this Web website, which includes an extensive multimedia library of assets that are related to evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in the biology standards. It contains seven short videos intended for use in the classroom. They can be streamed or purchased as DVDs.

Evolutionary biology remains an area of study that poses many important questions to answer, such as what triggers evolution and 에볼루션카지노 how quickly it takes place. This is especially true for humans' evolution, where it was difficult to reconcile religious beliefs that held that humans have a distinct place in the creation and a soul with the notion that human beings have innate physical traits were derived from Apes.

Additionally there are a myriad of ways that evolution could be triggered, with natural selection being the most popular theory. However, scientists also study other kinds of evolution like mutation, genetic drift and sexual selection, among others.

While many fields of scientific study have a conflict with literal interpretations found in religious texts, evolution biology has been the subject of intense debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, other religions have not.
