Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, there are still a lot of misconceptions about evolution. Pop science nonsense has led people to think that biologists don't believe in evolution.

This rich website - companion to the PBS series - provides teachers with materials that support evolution education and help avoid the kinds of myths that undermine it. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complex and difficult subject to teach well. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is especially true when discussing the meaning of the words themselves.

It is therefore essential to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, 에볼루션 사이트 does this in a clear and helpful manner. The site is a companion site to the show which first aired in 2001, but also functions as an independent resource. The material is presented in a way which aids navigation and orientation.

The site defines terms like common ancestor, gradual process and so on. These terms help to define the nature of evolution as well as its relation to other concepts in science. The site also provides an overview of how the concept of evolution has been tested and verified. This information can help dispel the myths created by creationists.

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

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

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

Deoxyribonucleic Acid: A massive biological molecular that holds the necessary information for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution include the interactions between predator and prey or 에볼루션카지노사이트 the parasite and the host.

Origins

Species (groups of individuals that are able to interbreed) evolve through an array of natural changes in the traits of their offspring. The changes can be triggered by a variety, including natural selection, genetic drift, and mixing of gene pools. The evolution of a new species could take thousands of years and the process can be slowed down or speeded up due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site tracks through time the evolution of different groups of animals and plants, focusing on major transitions in each group's history. It also examines the evolution of humans, which is a topic of particular importance to students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. The famous skullcap, with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year before the first edition of the Origin appeared, 에볼루션카지노사이트 (Testyourcharger.Com) it is extremely unlikely that Darwin had seen or heard of it.

The site is primarily one of biology however, it also has a lot of information on paleontology and geology. The Web site has a number of features that are particularly impressive, including an overview of the way that climate and geological conditions have changed over time. It also has an interactive map that shows the location of fossil groups.

The site is a companion to a PBS TV series but it could also be used as a source for 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 assistance) as well as the more specialized features of the museum's website. These links facilitate the transition from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are hyperlinks to John Endler's experiments with Guppies, 에볼루션 블랙잭 which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced an array of animals, plants and insects. Paleobiology, the study of these creatures within their geological environment, has many advantages over modern observational or experimental methods of studying evolutionary processes. In addition to examining processes and events that occur frequently or over a long period of time, paleobiology is able to examine the relative abundance of different species of organisms and their distribution in space over geological time.

The website is divided into various ways to learn about evolution that include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence to support the theory of evolution. The path also explores misconceptions about evolution as well as the history of evolutionary thinking.

Each of the main sections on the Evolution website is equally well-developed, and includes 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 resources, including animations, video clips and virtual labs as well as general textual content. The breadcrumb-like structure of the content assists with navigation and orientation on the large web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of the coral's relationships and 에볼루션카지노사이트 interactions with other organisms and is enlarged to show one clam, which can communicate with its neighbors and respond to changes in the conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a wide variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis, which is a key method to understand evolutionary changes.

Evolutionary Theory

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

One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that offers both depth and a variety of educational resources. The site offers a variety of interactive learning modules. It also has an "bread crumb structure" that allows students to move away from the cartoon-like style used in Understanding Evolution and onto elements on this large website more closely linked to the realms of research science. For instance an animation that introduces the concept of genetic inheritance links to a page that focuses on John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

Another helpful resource is the Evolution Library on this site, which has an extensive collection of multimedia assets connected to evolution. The content is organized into curriculum-based paths that parallel the learning goals established in the standards for biology. It contains seven videos specifically designed for classroom use, which can be streamed for no cost or 에볼루션카지노사이트 purchased on DVD.

Evolutionary biology remains a field of study that has many important questions, such as what causes evolution and the speed at which it occurs. This is particularly relevant for humans' evolution where it was a challenge to reconcile religious beliefs that humans have a distinct place in the creation and a soul, with the notion that our physical traits evolved from apes.

There are a myriad of other ways in which evolution could occur, with natural selection as the most popular theory. However scientists also study different kinds of evolution like mutation, genetic drift, and sexual selection, among other things.

While many scientific fields of study have a conflict with the literal interpretations of religious texts, the concept of evolution biology has been a source of intense debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
