What Is Evolution Site And Why Is Everyone Talking About It?
Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, misconceptions persist about the evolution. Pop science nonsense has led many people to think that biologists don't believe in evolution.
This rich website - companion to the PBS series - provides teachers with materials which support evolution education and help avoid the kinds of myths that undermine it. It's organized in the "bread crumb" format to make navigation and orientation easier.
Definitions
It's difficult to teach evolution well. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is particularly relevant to discussions about the meaning of the word itself.
As such, it is essential to define terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a simple and efficient way. The site is a companion site to the show which first aired in 2001, but it can also function as an independent resource. The material is organized in a way that makes it easy to navigate and comprehend.
The site defines terms like common ancestor, gradual process and adaptation. These terms help to define the nature of evolution as well as its relationship to other concepts in science. The website provides a summary of the way the concept of evolution has been tested. This information can help dispel the myths that are created by the creationists.
It is also possible to find a glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable characteristics to become more suited to a particular environment. This is a result of natural selection. Organisms with better-adapted traits are more likely than those with less adapted characteristics to survive and reproduce.
Common ancestor (also known as 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 contains the information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, called chromosomes. Mutations are the cause of new genetic information within cells.
Coevolution is the relationship between two species in which the evolution of one species are influenced by evolutionary changes in the other. Coevolution can be seen in the interaction of predator and prey, or parasite and hosts.
Origins
Species (groups of individuals who can interbreed) change through natural changes in the traits of their offspring. The changes can be triggered by a variety of factors such as 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 tracks the evolution of various groups of animals and plants over time, focusing on the major transitions that occurred in the history of each group. It also focuses on the evolutionary history of humans, a topic that is particularly important for students to understand.
Darwin's Origin was published in 1859, at a time when only a handful of antediluvian fossils of human beings had been discovered. The skullcap that is famous, along with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. 에볼루션 슬롯 is highly unlikely that Darwin was aware of the skullcap when it was published in 1858, one year after the publication of the first edition of The Origin. Origin.
The site is primarily one of biology however it also includes lots of information about paleontology and geology. 에볼루션 바카라 무료 of the most appealing features on the site are a timeline of events that illustrate the way in which climatic and geological conditions have changed over time, as well as a map of the distribution of some fossil groups listed on the site.
Although the site is a companion piece to the PBS television series, it also stands on its own as a valuable resource for teachers and students. The site is very well organized and provides clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These hyperlinks make it easy to transition from the cartoon-style 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 of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a variety of animals, plants, and insects. Paleobiology is the study of these creatures within their natural environment is a superior method of study over modern observational or research methods for exploring evolutionary phenomena. Paleobiology is able to study not only processes and events that occur frequently or over time, but also the distribution and frequency of different groups of animals in space over the course of the geological time.
The website is divided into several paths that can be chosen to learn about evolution. One of these paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The path also examines myths regarding evolution, and also the history of evolutionary thought.
Each of the other major sections of the Evolution site is equally constructed, with materials that support a variety of educational levels and pedagogical styles. In addition to general textual content, the site offers an extensive selection of multimedia and interactive resources including video clips, animations, and virtual labs. The breadcrumb-like organization of the content assists with navigation and orientation on the large website.
For example the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interactions with other organisms. Then, it narrows down to a single clam that can communicate with its neighbours and respond to changes in the water conditions at the level of the reef. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to the broad spectrum of topics in evolutionary biology. The content includes an overview of the role of natural selectivity and the concept of phylogenetics, an important method for understanding the evolution of changes.
Evolutionary Theory
Evolution is an underlying thread that connects all branches of biology. A rich collection of resources can help teachers teach about evolution across the life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides the depth and breadth of its educational resources. The site offers a variety of interactive learning modules. It also features an encased "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this huge site that are more closely tied to the field of research science. For example an animation that explains the idea of genetic inheritance connects to a page highlighting John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.
Another helpful resource is the Evolution Library on this Web website, which includes an extensive multimedia library of items that are related to evolution. The content is organized according to curricula-based paths that correspond to the learning objectives set out in the standards for biology. It includes seven short videos designed specifically for use in the classroom, and can be streamed for free or purchased on DVD.
A number of important questions remain at the core of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is particularly true for human evolution, where it's been difficult to reconcile the notion that the physical traits of humans were derived from apes, and the religions that believe that humanity is unique among living things and holds a a special place in creation with a soul.
There are also a number of other ways evolution can take place including natural selection, which is the most well-known theory. Scientists also study different types such as mutation, genetic drift and sexual selection.
While many scientific fields of study conflict with literal interpretations in religious texts, evolution biology has been the subject of intense debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
