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 believe that biologists aren't believers in evolution.
This rich Web site - companion to the PBS series offers teachers with resources which support evolution education and avoids the kinds of misconceptions that make it difficult to understand. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach effectively. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. 에볼루션 무료 바카라 is particularly relevant when discussing the definition of the words.
It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. It is an accompanying site for the 2001 series, but it is also a resource on its own. The material is presented in a nested fashion which aids navigation and orientation.
The site defines terms such as common ancestor and the gradual process. These terms help frame the nature and relationship of evolution with other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and verified. This information can be used to dispel misconceptions that have been created by creationists.
It is also possible to get a glossary of terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to be more suited to the environment. This is the result of natural selection. Organisms with more adaptable traits are more likely than those with less adaptable traits to reproduce and survive.
Common ancestor (also known as common ancestor): The most recent ancestral ancestor shared by two or more species. By analyzing DNA from these species, it is possible to determine the common ancestor.
Deoxyribonucleic Acid: A large biological molecular that holds the information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the source of new genetic information within cells.
Coevolution is a relation between two species where evolution of one species influence evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey, or host and parasite.
Origins
Species (groups that can crossbreed) change through a series of natural changes in the traits of their offspring. The changes can be triggered by a variety such as natural selection, genetic drift and mixing of gene pools. The development of a new species can take thousands of years and the process may be slowed down or speeded up by environmental factors like climate change or competition for food or habitat.
The Evolution site tracks through time the evolution of different groups of animals and plants, focusing on major transitions within each group's past. It also explores the human evolutionary roots and humans, a subject that is particularly important for students to comprehend.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The most famous among them was the 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. It is unlikely that Darwin knew about the skullcap, which was published in 1858, one year following the initial edition of The Origin.
The site is mostly one of biology however it also includes lots of information about paleontology and geology. The most impressive features of the website are a set of timelines which show the way in which climatic and geological conditions changed over time, and an outline of the geographical distribution of some of the fossil groups featured on the site.
Although the site is a companion to a PBS television series but it also stands on its own as a great source for teachers and students. The site is well-organized and offers clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated components of the museum's Web site. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are links to John Endler's research with Guppies, which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has led to many species of animals, plants and insects. Paleobiology is the study of these creatures in their geological environment is a superior method of study over modern observational or experimental methods for exploring evolutionary processes. Paleobiology is able to study not only the process and events that occur regularly or over time, but also the distribution and frequency of various animal groups in space throughout the geological time.
The website is divided into a variety of ways to learn about evolution, including "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence supporting the theory of evolution. The course also focuses on common misconceptions about evolution and the evolution theory's history.
Each of the other major sections of the Evolution site is equally created, with resources that support a variety of curriculum levels and pedagogical styles. In addition to the standard textual content, the site also has an extensive selection of multimedia and interactive resources, such as videos, animations and virtual labs. The breadcrumb-like structure of the content helps with navigation and orientation on the vast website.
For instance the page "Coral Reef Connections" gives a brief overview of coral relationships and their interaction with other organisms, then zooms in on a single clam that is able to communicate with its neighbours and respond to changes in the water conditions at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a wide range of topics in evolutionary biology. The information 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 a common thread that is found throughout all branches of biology. 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 a Web site that provides depth as well as broadness in terms of educational resources. The site features a wealth 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 large Web site more closely linked to the field of research science. For example an animation that explains the concept of genetic inheritance links to a page that focuses on John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.
The Evolution Library on this website contains a large multimedia library of materials that deal to evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning objectives set out in biology standards. It contains seven videos designed specifically for use in the classroom, and can be streamed at no cost or purchased on DVD.
Many important questions remain in the midst of evolutionary biology, such as what triggers evolution and how fast it happens. This is particularly true for human evolution, which has made it difficult to reconcile that the physical traits of humans evolved from apes and religious beliefs that claim that humanity is unique in the universe and has a special place in creation with a soul.
Additionally there are a variety of ways that evolution could be triggered with natural selection being the most popular theory. 에볼루션 무료 바카라 study other kinds like mutation, genetic drift and sexual selection.
While many scientific fields of study conflict with the literal interpretations of religious texts, the concept of 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 ideas of evolution, other religions haven't.
