Evolution Site - Teaching About Evolution

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

This rich Web site - companion to the PBS series - provides teachers with materials that support evolution education and avoids the kinds of misconceptions that make it difficult to understand. It's laid out in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to properly teach evolution. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. This is especially true when discussing the nature of the words themselves.

Therefore, it is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The site is a companion to the show that premiered in 2001, but it also functions as an independent resource. The information is organized in a way that makes it easy to navigate and understand.

The site defines terms such as common ancestor, the gradual process and adaptation. These terms help frame the nature of evolution as well as its relation to other concepts in science. The site gives a comprehensive overview of the manner that evolution has been examined. This information can be used to dispel myths that have been created 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 hereditary traits to become more suitable to their environment. This is the result of natural selection, which occurs when organisms with better-adapted characteristics are more likely to survive and reproduce than those with less adapted traits.

Common ancestor (also called common ancestor) is the most recent ancestor that is shared by two or more species. The common ancestor can be identified through analyzing the DNA of the species.

Deoxyribonucleic Acid: A massive biological molecular that holds the information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is the relationship between two species in which the evolutionary changes of one species influence evolutionary changes of the other. Coevolution can be observed in the interactions between predator and prey, or parasites and hosts.

Origins

Species (groups which can interbreed) develop by a series of natural variations in the traits of their offspring. The changes can be caused by a variety that include natural selection, genetic drift, and mixing of genes. The development of a new species could take thousands of years, and the process may be slowed down or speeded up by environmental conditions such as climate change or competition for food or habitat.

The Evolution site follows the emergence of various animal and plant groups and focuses on major changes within each group's past. It also explores the evolutionary history of humans and humans, a subject that is especially important for students to know.

When Darwin wrote the Origin, only a handful of antediluvian human fossils 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. It is unlikely that Darwin was aware of the skullcap when it was published in 1858, a year after the publication of the first edition of The Origin.

While the site is focused on biology, it offers a lot of information about geology and paleontology. Among the best features of the website are a series of timelines which show how climatic and 에볼루션카지노 geological conditions changed over time, as well as an interactive map of the distribution of some of the fossil groups featured on the site.

The site is a companion for the PBS TV series but it can also be used as an educational resource by teachers and students. The site is well-organized and offers clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) and 에볼루션게이밍 the more specific features on the museum's website. These hyperlinks make it easy to transition from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are links to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology is the study of these creatures within their geological context, has many advantages over modern observational or experimental methods for exploring evolutionary processes. Paleobiology is able to study not only the process and events that take place regularly or 에볼루션사이트 over time but also the relative abundance and distribution of different species of animals in space throughout geological time.

The site is divided into a variety of ways to learn about evolution which include "Evolution 101," which takes the user on a linear path through the nature of science and the evidence that supports the theory of evolution. The course also focuses on misconceptions about evolution as well as the history of evolutionary thinking.

Each of the main sections on the Evolution website is equally well-designed, with materials that are suited to a variety of educational levels and 에볼루션게이밍 teaching styles. The site includes a variety of interactive and multimedia content that include animations, video clips and virtual laboratories, in addition to its general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the large website.

For example, the page "Coral Reef Connections" provides a comprehensive 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 the water conditions that occur at the level of the reef. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a wide range of topics in evolutionary biology. The content includes an overview of the role of natural selectivity and the concept phylogenetics analysis which is a crucial tool to understand evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A rich collection of resources supports teaching about evolution across all life sciences.

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides the depth and the wide range of educational resources. The site features a wealth of interactive learning modules. It also has a "bread crumb structure" that assists students in moving away from the cartoon style of Understanding Evolution and onto elements on this large website more closely connected to the realms of research science. For instance an animation that explains the concept of genetic inheritance links to a page that highlights John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives outlined in the standards for biology. It contains seven short videos that are intended for use in the classroom. These can be streamed or 에볼루션 무료체험 purchased as DVDs.

A variety of crucial questions remain at the core of evolutionary biology, such as the factors that trigger evolution and the speed at which it occurs. This is particularly relevant for the evolution of humans, where it was difficult to reconcile religious beliefs that humanity has a unique place in creation and a soul with the notion that our physical traits originated from the apes.

There are a myriad of other ways evolution can occur and natural selection being the most well-known theory. However scientists also study different types of evolution such as mutation, genetic drift, and sexual selection, among others.

Although many scientific fields of study have a conflict with literal interpretations in religious texts, evolution biology has been the subject of intense debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, others haven't.
