Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions persist regarding evolution. People who have absorbed pop science nonsense often assume that biologists claim they do not believe in evolution.

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

Definitions

Evolution is a complicated and challenging subject to teach well. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition that confuses it. This is especially true when discussing the definition of the words.

It is important to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The site is both a companion for the 2001 series, and also a resource of its own. The content is presented in a nested fashion which aids navigation and orientation.

The site defines terms such as common ancestor, gradual process and 에볼루션 adaptation. These terms help frame the nature and significance of evolution to other scientific concepts. The site gives a comprehensive overview of the ways that evolution has been examined. This information can help dispel myths created by creationists.

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

Adaptation: The tendency of hereditary traits to become more suitable to a particular setting. This is the result of natural selection. Organisms with more adaptable characteristics are more likely than those with less-adapted traits to survive and reproduce.

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

Deoxyribonucleic acid: A large biological molecule that contains the information necessary for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are responsible for 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. Coevolution can be seen in the interactions between predator and prey, or parasite and hosts.

Origins

Species (groups of individuals who can interbreed) evolve through an array of natural changes in the characteristics of their offspring. These changes are caused by a variety of factors that include natural selection, genetic drift and mixing of genes. The evolution of a new species could take thousands of years, and the process could be slowed or increased due to environmental conditions, such as climate change or competition for food or habitat.

The Evolution site tracks the development of various animal and plant groups through time and focuses on the most significant changes that took place in the history of each group. It also focuses on human evolution as a subject that is of particular interest for students.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and 에볼루션 bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was one year before the first edition of the Origin appeared, it is highly unlikely that Darwin had heard or seen of it.

The site is mostly an online biology resource however it also includes a lot of information on paleontology and geology. One of the most appealing features on the site are a set of timelines that show how geological and climatic conditions changed over time, and a map of the distribution of some fossil groups that are featured on the site.

Although the site is a companion piece to the PBS television series, it also stands on its own as a valuable source for 에볼루션 룰렛 (Click on Pediascape) teachers and students. The site is well-organized and offers clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features of the museum website. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are hyperlinks to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to a variety of plants, animals and insects. Paleobiology is the study of these creatures in their geographical context and offers many advantages over modern observational and experimental methods in its exploration of evolutionary processes. Paleobiology focuses on not only the process and events that occur frequently or over time, but also the relative abundance and distribution of different groups of animals in space over the course of geological time.

The site is divided into several paths that can be chosen to learn about evolution. One of these paths, "Evolution 101," takes the viewer through the complexities and 에볼루션 코리아 evidence of evolution. The path also reveals common misconceptions about evolution as well as the history of evolutionary thought.

Each of the main sections of the Evolution website is equally well-developed, with materials that support a variety curriculum levels and teaching styles. In addition to the standard textual content, the site also has a wide range of multimedia and interactive resources like videos, 에볼루션카지노사이트 animations, and virtual laboratories. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the large web site.

For example, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interactions with other organisms. Then, it zooms in on a single clam that can communicate with its neighbors and respond to changes in water conditions that occur at the level of the reef. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The material includes a discussion on the importance of natural selection and the concept phylogenetics analysis, an important method for understanding the evolution of changes.

Evolutionary Theory

For biology students the concept of evolution is a major thread that binds all branches of the field. A rich collection supports teaching evolution across the disciplines of life science.

One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both depth and a variety of educational resources. The site has a variety of interactive learning modules. It also has a "bread crumb structure" that allows students to move away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely related to the worlds of research science. For example an animation that explains the notion of genetic inheritance leads to a page that highlights John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website contains a large multimedia library of assets related with evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives outlined in biology standards. It contains seven short videos specifically designed for use in classrooms. These can be streamed or purchased as DVDs.

A number of important questions remain at the heart of evolutionary biology, including what triggers evolution and how fast it happens. This is particularly true in the case of human evolution where it was a challenge to reconcile religious beliefs that held that humanity has a special place in creation and a soul, with the notion that human beings have innate physical traits originated from Apes.

Additionally, there are a number of ways in which evolution could be triggered with natural selection being the most popular theory. Scientists also study other kinds such as mutation, genetic drift, and sexual selection.

Many fields of inquiry conflict with literal interpretations of religious texts Evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, while others haven't.
