Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions persist about evolution. Pop science nonsense has led people to think that biologists don't believe in evolution.

This site, a companion to the PBS program that provides teachers with resources which support evolution education while avoiding the types of misconceptions that can undermine it. It's laid out in a "bread crumb" format to make navigation and orientation easier.

Definitions

Evolution is a complex and challenging subject to teach effectively. Many non-scientists are unable to grasp the concept and some scientists use a definition which confuses it. This is especially relevant to discussions about the meaning of the word itself.

It is essential to define terms used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient way. The site is a companion to the show which first aired in 2001, but also functions as an independent resource. The material is presented in a nested manner that assists in navigation and orientation.

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

It is also possible to access 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. It occurs when organisms with better adapted traits are more likely survive and reproduce than those with less adapted characteristics.

Common ancestor: The latest common ancestor of two or more different species. By studying the DNA of these species, 에볼루션사이트 it is possible to identify the common ancestor.

Deoxyribonucleic acid: A large biological molecule that holds the information necessary for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the source of new genetic information within cells.

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

Origins

Species (groups that can interbreed) develop through a series natural changes in their offspring's traits. The changes can be caused by a variety of factors, including natural selection, genetic drift, and mixing of genes. The evolution of new species could take thousands of years. Environmental conditions, like climate changes or competition for food or habitat can impede or accelerate the process.

The Evolution site tracks the development of a variety of groups of animals and plants over time, focusing on the major transitions that occurred in each group's history. It also explores human evolution and is a subject that is of particular interest to students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, a year before the first edition of the Origin was published, it's extremely unlikely that Darwin had ever heard of it.

While the site focuses on biology, it also includes a good deal of information about geology as well as paleontology. Among the best features on the site are a timeline of events that show how geological and climatic conditions have changed over time, as well as an outline of the distribution of some fossil groups listed on the site.

The site is a companion to the PBS television series, but it can also be used as an educational source for teachers and students. The site is extremely well-organized and offers clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's 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. In particular there are hyperlinks to John Endler's experiments using Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to a variety of plants, animals and insects. Paleobiology, the study of these creatures in their geological context offers many advantages over modern observational or research methods for exploring evolutionary phenomena. In addition to studying processes and events that take place regularly or over a long period of time, paleobiology is able to examine the relative abundance of different kinds of organisms as well as their distribution across geological time.

The website is divided into a variety of pathways to understanding evolution, including "Evolution 101," which takes the user on a linear path through the science of nature and the evidence supporting the theory of evolution. The path also reveals common misconceptions about evolution and the evolution theory's history.

Each of the other main sections of the Evolution site is equally well created, with resources that can be used to support a range of curriculum levels and pedagogical styles. In addition to the standard textual content, the site offers a wide range of interactive and multimedia resources including videos, animations and virtual labs. The breadcrumb-like organization of the content aids in navigation and orientation on the vast website.

For instance, the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interactions with other organisms. Then, it zooms in on a single clam that is able to communicate with its neighbors and react to changes in water conditions at the level of the reef. This page, along with the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a broad range of topics in evolutionary biology. The content also includes a discussion on the significance of natural selectivity and the concept of phylogenetics analysis as a key tool for understanding evolutionary changes.

Evolutionary Theory

Evolution is a common thread that connects all branches of biology. A rich collection supports teaching evolution across the disciplines of life science.

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that offers both the depth and the breadth in terms of its educational resources. The site features a wide range of interactive learning modules. It also has an "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 connected to the realms of research science. For instance an animation that explains the idea of genetic inheritance connects to a page highlighting John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of resources that are associated with evolution. The content is organized according to courses that are based on curriculum and follow the learning goals established in biology standards. It includes seven short videos intended for use in the classroom. They are available to stream or 에볼루션바카라 purchase as DVDs.

A variety of crucial questions remain in the midst of evolutionary biology, including the factors that trigger evolution and how fast it happens. This is especially applicable to human evolution where it has been difficult to reconcile the idea that the innate physical characteristics of humans were derived from apes and religions that believe that humanity is unique in the universe and has an enviable place in creation. It is a soul.

Additionally there are a myriad of ways that evolution could be triggered, with natural selection being the most popular theory. However, scientists also study other 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 controversy and opposition from religious fundamentalists. Certain religions have embraced their beliefs to evolution while others haven't.
