Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science nonsense has led many people to believe that biologists don't believe evolution.

This site, a companion to the PBS program that provides teachers with resources that support the evolution of education while avoiding the types of misconceptions that can make it difficult to understand. It's organized in a "bread crumb" format to facilitate navigation and 에볼루션 카지노 사이트 orientation.

Definitions

Evolution is a complex and challenging subject to teach well. People who are not scientists often have a difficult time understanding the subject, and some scientists even employ a definition that confuses it. This is particularly relevant when discussing the nature of the words themselves.

Therefore, it is essential to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site serves as an accompaniment to the 2001 series, and also a resource on its own. The material is presented in a nested fashion that assists in navigation and orientation.

The site defines terms such as common ancestor, the gradual process, and adaptation. These terms help frame the nature of evolution and its relationship to evolution to other concepts in science. The website then provides an overview of how the concept of evolution has been tested and verified. This information will help to dispel the myths created by creationists.

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

Adaptation is the tendency of heritable traits to be more suitable to their environment. This is the result of natural selection. Organisms with better-adapted traits are more likely than those with less-adapted traits to survive and reproduce.

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

Deoxyribonucleic acid: A massive biological molecule that contains information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution is the relationship between two species in which the evolution of one species are influenced by evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey or 무료 에볼루션 the parasite and the host.

Origins

Species (groups of individuals that are able to interbreed) evolve through natural changes in the characteristics of their offspring. These changes can be caused by various factors, including natural selection, gene drift, and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, like climate change or competition for food or habitat can impede or accelerate the process.

The Evolution site traces the emergence of a variety of animal and plant groups through time and focuses on the most significant shifts that occurred throughout the history of each group. It also focuses on the human evolutionary roots which is particularly important for students to comprehend.

Darwin's Origin was written in 1859, when only a few antediluvian fossils of human beings had been discovered. Among them was the famous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was one year before the first edition of the Origin was published, it's highly unlikely that Darwin had heard or seen of it.

While the site focuses on biology, it includes a good deal of information on geology and paleontology. Among the best features on the site are a timeline of events which show the way in which climatic and geological conditions have changed over time, and an interactive map of the geographical distribution of some fossil groups listed on the site.

Although the site is a companion piece to the PBS television series however, it can stand on its own as a valuable source for teachers and students. The site is well-organized and has clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These links make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms 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 has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and has numerous advantages over the modern observational and research methods of examining evolutionary phenomena. In addition to studying processes and events that take place frequently or over a long period of time, paleobiology is able to analyze the diversity of groups of organisms and their distribution in space over the course of geological time.

The Web site is divided into a variety of paths to learning evolution which include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence supporting the theory of evolution. The path also reveals common misconceptions about evolution as well as the evolution theory's history.

Each of the other main sections of the Evolution site is equally created, with resources that can support a variety of curriculum levels and 에볼루션바카라 pedagogical styles. The site includes a variety of interactive and multimedia resources which include videos, animations, and virtual labs in addition to general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the large web site.

For example, the page "Coral Reef Connections" provides an overview of the relationships between corals and 에볼루션카지노사이트 their interaction with other organisms. Then, it concentrates on a specific clam that can communicate with its neighbours and 에볼루션 카지노 사이트 respond to changes in the water conditions that take place at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to a broad spectrum of topics in evolutionary biology. The content includes an explanation of the significance of natural selectivity and the concept phylogenetics analysis as a key tool for understanding evolutionary changes.

Evolutionary Theory

Evolution is a common thread that connects all branches of biology. A rich collection of resources can help teachers teach about evolution across all life sciences.

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that provides depth as well as broadness in terms of educational resources. The site offers a range of interactive learning modules. It also features a nested "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely linked to the field of research science. For example an animation that introduces the notion of genetic inheritance leads to a page highlighting John Endler's experiments in artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated to evolution. The contents are organized into curriculum-based paths that parallel the learning goals established in the standards for biology. It contains seven videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD.

Evolutionary biology is still a field of study that poses many important questions, including what causes evolution and the speed at which it happens. This is particularly relevant in the case of human evolution where it was a challenge to reconcile religious beliefs that held that humanity has a unique position in the universe and a soul with the notion that our physical traits evolved from apes.

There are a variety of other ways in which evolution can occur, with natural selection as the most widely accepted theory. Scientists also study different types such as genetic drift and sexual selection.

While many fields of scientific study are in conflict with literal interpretations in religious texts, evolution biology has been the subject of intense debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
