7 Things You ve Never Knew About Evolution Site
Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, misconceptions persist about the evolution. People who have taken in the nonsense of pop science often believe that biologists do not believe in evolution.
This rich Web site, a companion to the PBS program, provides teachers with materials that promote evolution education, while avoiding the kinds of misconceptions which make it difficult to understand. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
It's not easy to effectively teach evolution. It is often misunderstood by non-scientists and even scientists are guilty of using definitions that confuse the issue. This is particularly true when discussing the meaning of the words themselves.
As such, it is important to define terms that are used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient way. The site is both a companion for the 2001 series, and also a resource of its own. The material is organized in a manner that makes it simpler to navigate and understand.
The site defines terms like common ancestor (or common ancestor), gradual process and adaptation. These terms help to frame the nature of evolution and its relationship to other concepts in science. The site also provides an overview of how the concept of evolution has been tested and validated. This information can be used to dispel misconceptions that have been created by creationists.
It is also possible to access a glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency of heritable characteristics to become more adaptable to a specific environment. This is a result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adaptable traits to survive and reproduce.
Common ancestor: The latest common ancestor of two or 에볼루션 more distinct species. By studying the DNA of these species it is possible to determine the common ancestor.
Deoxyribonucleic acid: A huge biological molecule that contains information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.
Coevolution is a relation between two species where evolutionary changes of one species influence evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or the parasite and the host.
Origins
Species (groups of individuals that are able to interbreed) evolve through a series 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 development of a new species could take thousands of years, and the process could be slowed or increased due to environmental conditions, such as climate change or competition for food or habitat.
The Evolution site follows the emergence of various species of plants and animals and focuses on major changes within each group's past. It also focuses on the evolutionary history of humans which is especially important for students to understand.
Darwin's Origin was published in 1859, when just a few antediluvian fossils of humans were discovered. The famous skullcap, 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. While the skullcap wasn't published until 1858, 에볼루션 슬롯 just one year before the first edition of the Origin appeared, it is extremely unlikely that Darwin had seen or heard of it.
While the site focuses on biology, 에볼루션 무료체험 it includes a good deal of information on geology and paleontology. The Web site has several aspects that are quite impressive, such as the timeline of how geological and climate conditions have changed over time. It also includes an interactive map that shows the location of fossil groups.
The site is a companion for the PBS television series, but it can also be used as an educational resource by teachers and students. The site is well-organized and offers easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features of the museum website. These links facilitate the transition from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. There are also links to John Endler's experiments with guppies, which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has produced a variety of plants, 에볼루션 animals and insects. Paleobiology is the study of these creatures in their geological context and has numerous advantages over modern observational and experimental methods of examining evolutionary processes. In addition to studying the processes and events that happen frequently or over a long period of time, paleobiology is able to study the diversity of groups of organisms and their distribution across the geological time.
The Web site is divided into a variety of pathways to understanding evolution which include "Evolution 101," which takes the user on a linear path through the science of nature and the evidence to support the theory of evolution. The path also explores common misconceptions about evolution and the evolution theory's history.
Each of the other sections of the Evolution site is similarly developed, with materials that can support a variety of educational levels and pedagogical styles. In addition to general textual content, the site features a wide range of multimedia and interactive content like video clips, animations, and virtual labs. The content is laid out in a nested bread crumb fashion that aids navigation and orientation on the web site.
For instance the page "Coral Reef Connections" gives a brief overview of coral relationships and their interaction with other organisms. Then, it concentrates on a specific clam that is able to communicate with its neighbors and react 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 website, provide an excellent introduction to a broad range of topics in evolutionary biology. The material includes an overview of the importance of natural selection and the concept of phylogenetics analysis as a key method for understanding the evolution of change.
Evolutionary Theory
For biology students evolution is a crucial thread that weaves together all the branches of the field. A wide range of resources helps teachers teach about evolution across the life sciences.
One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that provides depth and breadth in terms of its educational resources. The site offers a variety of interactive learning modules. It also features a "bread crumb structure" that allows students to move away from the cartoon style that is used in Understanding Evolution and onto elements of this vast website that are closely connected to the worlds of research science. For example an animation that explains the notion of genetic inheritance leads to a page that highlights John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.
The Evolution Library on this website contains a large multimedia library of assets related to evolution. The content is organized according to curricula-based paths that correspond to the learning objectives set out in biology standards. It contains seven videos specifically designed for use in classrooms, and can be streamed for no cost or purchased on DVD.
Evolutionary biology remains a field of study that has many important questions, such as the causes of evolution and how quickly it occurs. This is especially true for humans' evolution, where it was difficult to reconcile religious beliefs that held that humanity has a special place in the creation and a soul with the notion that human beings have innate physical traits evolved from Apes.
In addition there are a variety of ways that evolution can be triggered and natural selection is the most popular theory. Scientists also study different types such as mutation, genetic drift and sexual selection.
While many scientific fields of inquiry have a conflict with literal interpretations of the Bible evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, while others haven't.
