Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. People who have absorbed the nonsense of pop science often believe that biologists don't believe in evolution.

This rich website - companion to the PBS series - provides teachers with materials that support evolution education and help avoid the kinds of myths that make it difficult to understand. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It's difficult to teach evolution well. It is often misunderstood even by non-scientists, and even some scientists are guilty of using definitions that confuse the issue. This is particularly relevant when it comes to the definition of the words.

It is important to define terms 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 site to the show that premiered in 2001, but is also an independent resource. The content is presented in a way which aids navigation and orientation.

The site defines terms like common ancestor, 에볼루션 무료 바카라 the gradual process and adaptation. These terms help to frame the nature of evolution as well as its relation to other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and validated. This information can be used to dispel myths that have been engendered by creationists.

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

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

Common ancestor (also called common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of those species.

Deoxyribonucleic Acid: A massive biological molecular that contains the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

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

Origins

Species (groups of individuals that are able to interbreed) evolve through an array of natural changes in the traits of their offspring. The changes can be caused by a variety such as natural selection, genetic drift and mixing of genes. The development of a new species can take thousands of years and the process may be slowed down or speeded up due to environmental conditions, such as climate change or competition for 에볼루션 무료체험 food or habitat.

The Evolution site tracks the evolution of a variety of animal and plant groups through time and focuses on the most significant changes that took place in the history of each group. It also focuses on the evolutionary origin of humans which is particularly important for students to understand.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The famous skullcap, with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was first published in 1858, which was a year after the first edition of The Origin. Origin.

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

While the site is a companion piece to the PBS television show but it also stands on its own as a valuable source for teachers and students. The site is extremely well organized and provides clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These hyperlinks make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler’s experiments with guppies that illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life has led to a variety of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment and has numerous advantages over the modern observational and research methods for analyzing evolutionary phenomena. In addition to studying processes and events that take place regularly or over a lengthy period of time, paleobiology allows to study the relative abundance of various kinds of organisms as well as their distribution in space over the course of geological time.

The website is divided into various paths that can be chosen to learn about evolution. One of the paths, "Evolution 101," takes the viewer through the nature and evidence of evolution. The course also focuses on misconceptions regarding evolution, and also the history of evolutionary thinking.

Each of the other sections of the Evolution site is similarly developed, with materials that support a variety of educational levels and pedagogical styles. The site has a range of multimedia and 에볼루션바카라 interactive resources which include videos, animations, and virtual labs as well as general textual content. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the vast web site.

For instance the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms, then zooms in on a single clam that can communicate with its neighbours and respond to changes in water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages gives a good introduction to the many areas of evolutionary biology. The content also includes an overview of the significance of natural selectivity and the concept phylogenetics analysis, an important tool to understand evolutionary change.

Evolutionary Theory

For biology students evolution is a crucial thread that binds all the branches of the field. A rich collection supports teaching evolution across the disciplines of life science.

One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of an Web page that provides depth and broadness in terms of educational resources. The site has a wide array of interactive learning modules. It also features an encased "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the field of research science. An 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 useful resource is the Evolution Library on this web site, which has an extensive multimedia library of assets connected to evolution. The content is organized into curriculum-based paths that parallel the learning objectives set out in the standards for biology. It includes seven short videos designed specifically for use in classrooms, and can be streamed for no cost or purchased on DVD.

Evolutionary biology is still a field of study with a lot of important questions, such as what causes evolution and how fast it happens. This is especially true for the evolution of humans which was a challenge to reconcile religious beliefs that humanity has a unique place in creation and a soul with the notion that our physical traits were derived from apes.

There are also a number of other ways evolution can take place and natural selection being the most popular theory. Scientists also study different types such as mutation, genetic drift, and sexual selection.

While many fields of scientific study have a conflict with literal interpretations found in religious texts, evolution biology has been a source of intense debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, other religions haven't.
