Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution remain. People who have been exposed to popular science myths often assume that biologists claim they don't believe in evolution.

This rich Web site - companion to the PBS series It provides teachers with materials that promote evolution education and avoid the kinds of misconceptions that undermine it. It's organized in the "bread crumb" format to make navigation and orientation easier.

Definitions

Evolution is a complex and challenging subject to teach effectively. It is often misunderstood by non-scientists, and even scientists use definitions that confuse the issue. This is especially relevant to discussions on the definition of the word itself.

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 useful way. The site is a companion to the show which first aired in 2001, 에볼루션 바카라 무료체험 but is also an independent resource. The material is organized in a way that makes it easy to navigate and understand.

The site defines terms such as common ancestor, gradual process and so on. These terms help frame the nature of evolution and its relation to other scientific concepts. The site gives a comprehensive overview of the way in which evolution has been tested. This information can help dispel myths that are created by the creationists.

It is also possible to find a glossary of terms that are used in evolutionary biology. These terms include:

Adaptation is the tendency of heritable traits to become better suited to an environment. This is the result of natural selection. It occurs when organisms with better adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.

Common ancestor (also called common ancestor) The most recent ancestor shared by two or more species. By studying the DNA of these species, it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A large biological molecular that holds the information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form 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 of one species are influenced by evolutionary changes in the other. Coevolution can be observed through the interaction between predator 에볼루션 바카라 [a cool way to improve] and prey, or parasite and hosts.

Origins

Species (groups of individuals that can interbreed) change through an array of natural changes in the characteristics of their offspring. The causes of these changes are many factors, such as natural selection, gene drift and mixing of the gene pool. The development of a new species may take thousands of years and the process may be slowed down or speeded up by environmental factors like climate change or competition for food or habitat.

The Evolution site traces through time the emergence of various species of plants and animals and focuses on major changes in each group's history. It also explores human evolution as a subject that is of particular interest to students.

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

The site is mostly an online biology resource however it also includes lots of information about paleontology and geology. The website has numerous features that are especially impressive, such as the timeline 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 for a PBS television series, but it could also be used as a resource by teachers and students. The site is well-organized and offers clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and 무료 에볼루션 the more specific elements of the museum Web site. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and 에볼루션 사이트 has many advantages over the current observational and experimental methods for 무료 에볼루션 바카라 사이트 - blogs.cornell.edu, analyzing evolutionary processes. In addition to examining processes and events that take place frequently or over a long period of time, paleobiology is able to study the diversity of groups of organisms and their distribution throughout the geological time.

The site is divided into various options to study the subject of evolution. One of the paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The path also explores misconceptions about evolution, as well as the history of evolutionary thinking.

Each of the other major sections of the Evolution site is similarly created, with resources that support a variety of curriculum levels and 에볼루션 바카라사이트 pedagogical styles. The site has a range of interactive and multimedia content that include videos, animations, and virtual labs, in addition to its general textual content. The breadcrumb-like arrangement of the content helps with navigation and orientation on the large web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of the relationships between corals, their interaction with other organisms and zooms in to one clam that is able to communicate with its neighbours and respond to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to the broad range of topics in evolutionary biology. The content also includes a discussion on the role of natural selectivity and the concept phylogenetics analysis as a key method for understanding the evolution of changes.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. 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 excellent example of an Web site that provides depth and a variety of educational resources. The site has a wide array of interactive learning modules. It also has an encased "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the world of research science. For instance an animation that introduces the idea of genetic inheritance connects to a page that highlights John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of materials that deal with evolution. The content is organized according to curriculum-based paths that parallel the learning objectives outlined in biology standards. It contains seven short videos designed for use in classrooms. These are available to stream or purchase as DVDs.

A number of important questions remain at the heart of evolutionary biology, 무료 에볼루션 such as what causes evolution to occur and how fast it happens. This is especially relevant to human evolution, where it has been difficult to reconcile the idea that the physical characteristics of humans were derived from apes with religions that believe that humanity is unique among living things and has a special place in creation. It is a soul.

There are a variety of other ways evolution could occur, with natural selection as the most well-known theory. However scientists also study other kinds of evolution like genetic drift, mutation, and sexual selection, among others.

Although many scientific fields of study conflict with the literal interpretations of religious texts, evolution biology has been a source of intense debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, but others haven't.
