Evolution Site - Teaching About Evolution

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

This rich website - companion to the PBS series - provides teachers with materials that support evolution education and avoids the kinds of misconceptions that hinder it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complex and difficult subject matter to teach well. It is often misunderstood even by non-scientists, and even some scientists have been guilty of using an interpretation that is confusing the issue. This is especially relevant when discussing the nature of the words themselves.

It is therefore important to define the terms used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful way. It is a companion for the 2001 series, but it is also a resource on its own. The content is presented in a way that aids navigation and orientation.

The site defines terms like common ancestor and gradual process. These terms help frame the nature of evolution and its relationship to other concepts in science. The website then provides an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel the myths created by creationists.

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

Adaptation is the tendency of hereditary traits to become more suited to the environment. This is the result of natural selection, which happens when organisms that have better-adapted traits are more likely survive and reproduce than those with less adapted traits.

Common ancestor: The most recent common ancestor of two or more species. The common ancestor can be identified through analyzing the DNA of the species.

Deoxyribonucleic Acid: A huge biological molecular containing the necessary information for cell replication. The information is contained in a sequence of nucleotides that are strung together into 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 in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or parasite and host.

Origins

Species (groups which can interbreed) change through a series natural changes in their offspring's traits. 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 could take thousands of years and the process can be slowed or increased due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site tracks the evolution of a variety of species of plants and animals over time and focuses on the most significant shifts that occurred throughout the history of each group. It also focuses on human evolution as a subject that is of particular interest to students.

Darwin's Origin was written in 1859, at a time when only a handful of antediluvian fossils of humans had been found. The most famous among them was the skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, which was a year following the initial edition of The Origin.

While the site is focused on biology, it contains a wealth of information about geology and paleontology. One of the most appealing features of the Web site are a series of timelines which show the way in which climatic and geological conditions have changed over time, and a map of the geographical distribution of some of the fossil groups featured on the site.

While the site is a companion piece to a PBS television series however, it can stand on its own as an excellent source for teachers and students. The site is well-organized and provides clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) and 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. Particularly there are links to John Endler's research with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of animals, plants, and insects. Paleobiology, the study of these creatures within their geological context offers many advantages over modern observational or research methods of studying evolutionary processes. Paleobiology can examine not only the process and events that take place frequently or over time, but also the distribution and frequency of different groups of animals across the geological time.

The website is divided into several options to study the subject of evolution. One of these paths, "Evolution 101," walks the reader through the evolution of nature and the evidence of evolution. The course also focuses on common misconceptions about evolution and the evolution theory's history.

Each of the main sections of the Evolution website is equally well-designed, with materials that support a variety curriculum levels and teaching styles. In addition to the standard textual content, the site features an extensive selection of interactive and multimedia resources like video clips, animations, and virtual labs. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation within the large Web site.

The page "Coral Reef Connections" For instance, it gives a brief overview of the coral's relationships, their interaction with other organisms, and then zooms in to a single clam, which is able communicate with its neighbors and react to changes in conditions of the water at the reef level. This page, as well as the other multidisciplinary, 에볼루션 카지노 multimedia, and interactive pages on the site, offer an excellent introduction to a wide spectrum of topics in evolutionary biology. The material also provides an explanation of the role of natural selection as well as the concept of phylogenetic analysis, which is a key method to understand evolutionary change.

Evolutionary Theory

For biology students evolution is a crucial thread that weaves together all branches of the field. A wide selection of resources helps teachers teach evolution across the life science disciplines.

One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that provides depth and a variety of educational resources. The site has a variety of interactive learning modules. It also features a nested "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely linked to the field of research science. Animation that introduces the concept of genetics, which links to a page that highlights John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad.

Another helpful resource is the Evolution Library on this site, which contains an extensive library of multimedia resources that are related to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives set out in biology standards. It contains seven videos that are designed for use in classrooms. They are available to stream or purchase as DVDs.

A number of important questions remain at the heart of evolutionary biology, including what causes evolution to occur and 에볼루션 무료체험 how fast it occurs. This is particularly relevant for humans' evolution where it was a challenge to reconcile religious beliefs that humanity has a special place in creation and a soul with the notion that our physical traits were derived from the apes.

There are a myriad of other ways in which evolution could occur and natural selection being the most widely accepted theory. Scientists also study other types such as genetic drift and sexual selection.

Many fields of inquiry have a conflict with the literal interpretations of the Bible, 에볼루션 코리아 무료에볼루션 바카라 체험 (Check Out securityholes.science) evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, other religions haven't.
