Evolution Site - Teaching About Evolution

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

This rich Web site, a companion to the PBS program, provides teachers with materials that support the evolution of education while avoiding the types of misconceptions that undermine it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and challenging subject to teach well. It is often misunderstood by non-scientists, and even some scientists use an interpretation that is confusing the issue. This is especially true when discussing the nature of the words themselves.

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 helpful manner. The site serves as an accompaniment to the 2001 series, but it is also a resource on its own. The content is presented in a way that assists in navigation and orientation.

The site defines terms such as common ancestor, gradual process and so on. These terms help frame the nature and significance of evolution to other concepts in science. The site gives a comprehensive overview of the ways in which evolution has been tested. This information can be used to dispel misconceptions that have been engendered by creationists.

You can also consult a glossary that includes terms used in evolutionary biology. These terms include:

Adaptation is the tendency of hereditary traits to become more suitable to their environment. This is the result of natural selection. It occurs when organisms that are more adaptable traits are more likely to survive and reproduce than those with less adaptable characteristics.

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

Deoxyribonucleic Acid: A huge biological molecular that contains the necessary information for cell replication. The information is contained in a sequence of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the cause of new genetic information within cells.

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

Origins

Species (groups of individuals that are able to interbreed) evolve through an array of natural changes in the characteristics of their offspring. The changes can be caused by a variety of causes that include natural selection, genetic drift, and mixing of genes. The development of a new species can take thousands of years, and the process can be slowed down or speeded up by environmental conditions such as climate change or 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 within each group's past. It also focuses on human evolution, which is a topic of particular importance to students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. Among them was the famous skullcap and bones that were 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 first published in 1858, a year after the publication of the first edition of The Origin.

While the site focuses on biology, it includes a good deal of information on geology and paleontology. The site offers a number of aspects that are quite impressive, such as a timeline of the way that climate and geological conditions have changed over time. It also features maps that show the locations of fossil groups.

The site is a companion for a PBS television series, but it can also be used as a source for teachers and students. The site is well-organized and offers easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features of the museum website. These hyperlinks make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. Particularly, there are links to John Endler's experiments with Guppies that 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 within their geographical context and offers numerous advantages over the modern observational and research methods of examining evolutionary processes. Paleobiology focuses on not only processes and events that take place regularly or 에볼루션사이트 over time, but also the distribution and 에볼루션 바카라 무료 frequency of different groups of animals in space throughout the geological time.

The site is divided into various paths that can be chosen to gain knowledge about evolution. One of these paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also reveals the most common misconceptions about evolution, as well as the evolution of thought.

Each of the other main sections of the Evolution site is equally developed, with materials that support a variety of curriculum levels and pedagogical styles. In addition to the standard textual content, the site offers a wide range of multimedia and interactive resources including video clips, animations, and virtual labs. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the large Web site.

For 에볼루션 바카라사이트 example, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms. It then zooms in on a single clam that can communicate with its neighbours and respond to changes in water conditions at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The information also includes a discussion of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool in understanding evolutionary change.

Evolutionary Theory

For biology students, evolution is a key thread that binds all branches of the field. A wide range of resources can help teachers teach about evolution across all life sciences.

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of an Web site that provides depth and broadness in terms of educational resources. The site has a wide array 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 large Web site more closely linked to the world of research science. An animation that introduces students to the concept of genetics links to a page about John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in biology standards. It contains seven videos that are designed for classroom use. These can be viewed online or purchased as DVDs.

A number of important questions remain at the heart of evolutionary biology, such as the factors that trigger evolution and the speed at which it occurs. This is particularly true in the case of human evolution, 에볼루션코리아 where it was difficult to reconcile religious beliefs that held that humanity has a special position in the universe and a soul with the idea that innate physical traits evolved from the apes.

In addition, there are a number of ways that evolution can occur with natural selection being the most widely accepted theory. Scientists also study different types like mutation, genetic drift and sexual selection.

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