Evolution Site - Teaching About Evolution

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

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

Definitions

It's not easy to effectively teach evolution. It is often misunderstood by non-scientists and even some scientists are guilty of using definitions that confuse the issue. This is particularly relevant to discussions about the definition of the word itself.

Therefore, it is important to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site is both an accompanying site for the 2001 series, and also a resource of its own. The content is presented in a structured way that makes it easy to navigate and comprehend.

The site defines terms such as common ancestor, gradual process, and adaptation. These terms help frame the nature of evolution and its relationship to evolution with other scientific concepts. The website then provides an overview of how the concept of evolution has been vetted and confirmed. This information can be used to dispel the myths that have been propagated by the creationists.

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

Adaptation: The tendency for hereditary traits to become more suitable to a particular setting. This is due to natural selection, which happens when organisms that are better adapted characteristics are more likely to survive and 에볼루션사이트 reproduce than those with less adaptable traits.

Common ancestor: The latest common ancestor of two or more distinct species. By analyzing DNA from these species, it is possible to identify the common ancestor.

Deoxyribonucleic acid: A huge biological molecule that contains the information required for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are the source of new genetic information within cells.

Coevolution is a relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be seen in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups of individuals who can interbreed) change through an array of natural changes in the characteristics of their offspring. The causes of these changes are various factors, 에볼루션 바카라사이트 블랙잭 [www.2Heartsdating.com] including natural selection, gene drift, and mixing of the gene pool. The development of a new species could take thousands of years and the process may be slowed down or accelerated by environmental conditions such as climate change or 에볼루션사이트 the competition for food or habitat.

The Evolution site tracks through time the evolution of different animal and plant groups and focuses on major changes in each group's history. It also examines the evolution of humans as a subject of particular importance to students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. One of them was the infamous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap when it was published in 1858, a year after the first edition of The Origin.

The site is primarily an online biology resource however it also includes a lot of information on paleontology and geology. Among the best features of the website are a timeline of events that illustrate how climatic and geological conditions have changed over time, as well as a map of the geographical distribution of some of the fossil groups featured on the site.

While the site is a companion to a PBS television show but it also stands on its own as an excellent source for teachers and students. The site is well-organized, and provides clear links to the introductory content of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features of 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. There are also links to John Endler's experiments with guppies, which 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 in their natural environment and has numerous advantages over the modern observational and research methods for analyzing evolutionary phenomena. Paleobiology can examine not only the process and events that occur regularly or over time, 에볼루션 카지노 but also the distribution and frequency of different species of animals in space throughout the geological time.

The website is divided into several options to learn about evolution. One of the paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The path also reveals common misconceptions about evolution as well as the evolution theory's history.

Each of the main sections on the Evolution website is equally well-developed, with materials that support a variety curriculum levels and teaching styles. In addition to general textual content, the site also has an array of multimedia and interactive content, such as videos, animations and virtual laboratories. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the large Web site.

For example the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interactions with other organisms. Then, it narrows down to a single clam that is able to communicate with its neighbors and respond to changes in the water conditions at the level of the reef. This page, along with the other multidisciplinary interactive and multimedia pages offers a great introduction to a variety of topics in evolutionary biology. The content also includes an explanation of the importance of natural selection and the concept of phylogenetics as a key tool to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach evolution across all 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 the depth and breadth of its educational resources. The site has a wide array of interactive learning modules. It also has an "bread crumb structure" that helps students move away from the cartoon style used in Understanding Evolution and onto elements of this vast website that are closely related to the worlds of research science. An animation that introduces students to the concept of genetics links to a page that highlights John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.

The Evolution Library on this website has a huge multimedia library of materials that deal to evolution. The contents are organized into courses that are based on curriculum and follow the learning goals established in the standards for biology. It includes seven short videos specifically designed for use in classrooms, and can be streamed for free or purchased on DVD.

Evolutionary biology remains an area of study that has many important questions, including what triggers evolution and how fast it occurs. This is particularly true for human evolution, which has made it difficult to reconcile the idea that the physical characteristics of humans derived from apes, and the religions that believe that humanity is unique among living things and has a special place in creation with soul.

There are a myriad of other ways in which evolution can take place including natural selection, which is the most well-known theory. However scientists also study other kinds of evolution like mutation, genetic drift and sexual selection, among others.

While many fields of scientific study have a conflict with the literal interpretations of religious texts, the concept of evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the ideas of evolution, other religions have not.
