How To Find Out If You're Prepared To Evolution Site
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution remain. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.
This site, which is a companion to the PBS series offers teachers with resources that support evolution education and avoids the kinds of misinformation that can undermine it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
Evolution is a complex and difficult subject to teach effectively. Many non-scientists are unable to grasp the concept, and some scientists even employ a definition that confuses it. This is particularly relevant to debates about the definition of the word itself.
It is therefore essential to define the terms that are 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 accompaniment to the 2001 series, and it is also a resource on its own. The information is organized in a manner that makes it easier to navigate and comprehend.
The site defines terms such as common ancestor and gradual process. These terms help to define the nature of evolution and its relation to other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and confirmed. This information can help dispel myths created by creationists.
You can also access a glossary that includes terms used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable characteristics to become more suitable to a particular setting. This is due to natural selection. It occurs when organisms with better-adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor (also called common ancestor): The most recent ancestor that is shared by two or more species. The common ancestor can be identified by studying the DNA of those species.
Deoxyribonucleic Acid: A large biological molecular that holds the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts.
Origins
Species (groups of individuals that can interbreed) evolve through an array of natural changes in the characteristics of their offspring. The changes can be triggered by a variety that include natural selection, genetic drift, and mixing of genes. The evolution of a new species may take thousands of years and the process can be slowed or increased by environmental conditions such as climate change or the competition for food or habitat.
The Evolution site traces through time the evolution of different animal and plant groups with a focus on major changes within each group's past. It also examines the evolution of humans, which is a topic of particular importance to students.
Darwin's Origin was published in 1859, at a time when only a handful of antediluvian fossils of humans were 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 as an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was a year before the first edition of the Origin appeared, it is very unlikely that Darwin had heard or seen of it.
The site is mostly one of biology however it also includes many details on paleontology and geology. The website has a number of features that are particularly impressive, such as the timeline of how climate and geological conditions have changed over time. It also has maps that show the locations of fossil groups.
Although 에볼루션카지노사이트 is a companion piece to a PBS television series but it also stands on its own as an excellent source for teachers and students. The site is extremely well organized and provides clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized components of the museum's Web site. These links make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly, there are links to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has produced many species of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and has many advantages over the modern observational and research methods of examining evolutionary phenomena. In addition to exploring processes and events that occur frequently or over a long period of time, paleobiology is able to analyze the relative abundance of different kinds of organisms as well as their distribution across the course of geological time.
The site is divided up 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 path also examines myths about evolution as well as the history of evolutionary thought.
Each of the main sections on the Evolution website is equally well-developed, with materials that can be used to support a variety of educational levels and teaching styles. The site includes a variety of interactive and multimedia resources, including video clips, animations and virtual laboratories as well as general textual content. The breadcrumb-like arrangement of the content helps with navigation and orientation on the large web site.
For instance the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms, then narrows down to a single clam that can communicate with its neighbors and react to changes in water conditions that occur at the level of the reef. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a broad variety of topics in evolutionary biology. The content also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is a crucial tool for understanding the evolution of changes.
Evolutionary Theory
Evolution is an underlying thread that runs through all branches of biology. A vast collection of books helps in teaching evolution across all life science disciplines.
One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web site that provides the depth and the breadth in terms of its educational resources. The site has a variety 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 on this large website more closely related to the fields of research science. An animation that introduces the concept of genetics, which links to a page about John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.
Another helpful resource is the Evolution Library on this Web site, which contains an extensive library of multimedia items related to evolution. The content is organized into curricula-based paths that correspond to the learning objectives outlined in the biology standards. It includes seven short videos specifically designed for classroom use, which can be streamed for free or purchased on DVD.
Evolutionary biology is an area of study that has many important questions to answer, such as the causes of evolution and how quickly it occurs. This is especially true for the evolution of humans which was a challenge to reconcile religious beliefs that held that humans have a distinct place in creation and a soul, with the notion that human beings have innate physical traits originated from Apes.
In addition there are a variety of ways in which evolution could occur and natural selection is the most widely accepted theory. However, scientists also study other kinds of evolution, such as mutation, genetic drift and sexual selection, among others.
While many fields of scientific study conflict with literal interpretations found in religious texts, the concept of evolution biology has been the subject of intense debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, while others haven't.
