Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions about evolution. Pop science nonsense has led people to believe that biologists aren't believers in evolution.

This rich website - companion to the PBS series offers teachers with resources which support evolution education and avoid the kinds of myths that make it difficult to understand. 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 matter to teach effectively. It is often misunderstood by non-scientists, and even some scientists use a definition that confuses the issue. This is especially relevant when it comes to the definition of the words.

Therefore, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, 에볼루션 바카라 사이트코리아 (Highly recommended Site) does this in a simple and efficient way. The site is both an accompaniment to the 2001 series, but also a resource of its own. The material is presented in a way that assists in navigation and orientation.

The site defines terms like common ancestor, gradual process and so on. These terms help frame the nature of evolution and its relation to other concepts in science. The website then provides an overview of how the concept of evolution has been tested and validated. This information can be used to dispel the myths that have been propagated by the creationists.

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

Adaptation: The tendency of 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 adaptable traits to reproduce and survive.

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

Deoxyribonucleic acid: A large biological molecule that contains information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, referred to as chromosomes. Mutations are the basis for new genetic information in cells.

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

Origins

Species (groups that can interbreed) develop by a series of natural variations in the traits of their offspring. The causes of these changes are various factors, including natural selection, gene drift, and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food and habitat can slow or speed up the process.

The Evolution site tracks the development of a number of different animal and plant groups through time with a focus on the key changes that took place in each group's history. It also explores human evolution and is a subject of particular importance to students.

Darwin's Origin was published in 1859, when only a few antediluvian fossils of human beings had been discovered. The famous skullcap, along with the bones associated with 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, which was a year before the first edition of the Origin appeared, it is very unlikely that Darwin had ever heard of it.

While the site is focused on biology, it also offers a lot of information on geology and paleontology. The website has a number of features that are especially impressive, such as an overview of how geological and climate conditions have changed over time. It also features maps that show the locations of fossil groups.

The site is a companion for the PBS television series, but it can also be used as a resource by teachers and students. The site is well-organized, and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features on the museum's website. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. Particularly, there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in many species of plants, animals and insects. Paleobiology is the study of these creatures in their geographical context and offers many advantages over the current observational and experimental methods for analyzing evolutionary phenomena. In addition to exploring processes and events that occur frequently or over a long period of time, paleobiology is able to study the diversity of kinds of organisms as well as their distribution across the geological time.

The site is divided into a variety of paths to learning evolution, including "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence supporting the theory of evolution. The path also explores common misconceptions about evolution and the history of evolutionary thought.

Each of the main sections of the Evolution website is equally well-designed, with materials that can be used to support a variety of curriculum levels and teaching styles. The site has a range of multimedia and 에볼루션바카라사이트 interactive resources which include video clips, animations and virtual laboratories in addition to general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the massive website.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of the coral's relationships and their interactions with other organisms, and 에볼루션바카라사이트 then zooms in on a single clam, which can communicate with its neighbors and respond to changes in water conditions that occur on the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, provides an excellent introduction to a variety of topics in evolutionary biology. The content also includes a discussion on the role of natural selectivity and the concept of phylogenetics analysis as a key method for understanding the evolution of change.

Evolutionary Theory

For biology students, 에볼루션 사이트 evolution is a key thread that binds all branches of the field. A wide range of resources helps teachers teach about evolution across the life sciences.

One resource, the companion to PBS's television series Understanding Evolution is an excellent example of an Web page that offers both depth as well as broadness in terms of educational resources. The site offers a range of interactive learning modules. It also has a nested "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. For example an animation that introduces the idea of genetic inheritance connects to a page highlighting John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.

Another useful resource is the Evolution Library on this web site, which contains an extensive library of multimedia items related to evolution. The content is organized into 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 classroom use. These are available to stream or purchase as DVDs.

Evolutionary biology is an area of study that poses many important questions, such as what triggers evolution and how quickly it happens. This is especially true in the case of human evolution which was a challenge to reconcile religious beliefs that humanity has a special place in creation and a soul, with the notion that our physical traits were derived from the apes.

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

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