Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution remain. Pop science nonsense has led many people to believe that biologists aren't believers in evolution.

This rich Web site, which is a companion to the PBS program that provides teachers with resources which support evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's organized in a "bread crumb" format to aid in navigation and 무료에볼루션 orientation.

Definitions

Evolution is a complex and challenging subject to teach effectively. Non-scientists often misunderstand the subject and some scientists use a definition that confuses it. This is particularly relevant when it comes to the definition of the words.

It is crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The website is a companion to the show which first aired in 2001, but is also an independent resource. The material is presented in a nested fashion that aids navigation and orientation.

The site defines terms such as common ancestor, the gradual process, and adaptation. These terms help to define the nature and significance of evolution to other concepts in science. The site also provides an overview of how the concept of evolution has been vetted and validated. This information can help dispel the myths created by 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 suitable to a particular setting. This is a result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less-adapted traits to reproduce and survive.

Common ancestor: The latest common ancestor of two or 에볼루션 more distinct species. By analyzing DNA from these species it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular containing the information required for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are responsible for 에볼루션 the creation of new genetic information within cells.

Coevolution is a relationship between two species where evolution of one species are influenced evolutionary changes of the other. Examples of coevolution include the interactions between predator and prey or host and parasite.

Origins

Species (groups that can crossbreed) develop through a series natural changes in their offspring's traits. The changes can be caused by a variety of causes that include natural selection, genetic drift and gene pool mixing. The evolution of a new species may take thousands of years and the process can be slowed or increased due to environmental conditions, such as climate change or competition for food or habitat.

The Evolution site follows the emergence of various species of plants and animals, focusing on major transitions in each group's history. It also explores the evolutionary history of humans, a topic that is crucial for students to know.

Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans were discovered. One of them was the infamous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year after the first edition of the Origin was published, it's extremely unlikely that Darwin had seen or heard of it.

The site is mostly an online biology resource however it also includes a lot of information on geology and paleontology. Among the best features of the website are a series of timelines that show how climatic and 에볼루션 geological conditions have changed over time as well as an outline of the geographical distribution of some fossil groups that are featured on the site.

While the site is a companion piece to a PBS television show but it also stands on its own as a great source for teachers and students. The site is well-organized and has clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These hyperlinks help users move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies, which illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in an array of plants, animals and insects. Paleobiology, the study of these creatures in their natural environment, has many advantages over modern observational or experimental methods of studying evolutionary processes. Paleobiology can examine not only the process and events that take place regularly or over time, but also the relative abundance and distribution of various animal groups across geological time.

The Web site is divided into a variety of paths to learning evolution, including "Evolution 101," which takes the user on a linear path through the science of nature and the evidence to support the theory of evolution. The path also reveals common misconceptions about evolution and the evolution of thought.

Each of the main sections of the Evolution website is equally well-developed, with materials that can be used to support a variety of levels of curriculum and teaching methods. The site includes a variety of interactive and multimedia content, including video clips, animations and virtual laboratories, in addition to its general textual content. The breadcrumb-like structure of the content assists with navigation and orientation on the vast Web site.

The page "Coral Reef Connections", for example, gives a brief overview of coral relationships and interactions with other organisms and then is enlarged to show one clam that can communicate with its neighbors and react to changes in conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to the broad variety of topics in evolutionary biology. The information also includes an overview of the importance of natural selection and the concept of phylogenetic analysis which is a crucial tool for understanding the evolution of changes.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life science.

One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that offers both depth and a variety of educational resources. The site features a wide range of interactive learning modules. It also features a nested "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. An animation that introduces students to the concept of genetics is linked to a page that highlights John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.

The Evolution Library on this website has a huge multimedia library of materials that deal to evolution. The content is organized into curricula-based paths that correspond to the learning objectives set out in biology standards. It contains seven videos designed specifically for use in classrooms, and can be streamed for free or purchased on DVD.

Many important questions remain in the midst of evolutionary biology, including the factors that trigger evolution and the speed at which it occurs. This is particularly relevant in the case of human evolution which was a challenge to reconcile religious beliefs that held that humanity has a unique place in creation and a soul, with the notion that human beings have innate physical traits originated from Apes.

In addition, there are a number of ways that evolution could be triggered, with natural selection being the most widely accepted theory. However scientists also study other types of evolution such as genetic drift, mutation, 바카라 무료 에볼루션 (www.stes.tyc.edu.Tw) and sexual selection, among others.

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