How To Recognize The Evolution Site To Be Right For You
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution persist. Pop science fiction has led a lot of people to believe that biologists aren't believers in evolution.
This site, which is a companion to the PBS series - provides teachers with materials that support evolution education and avoids the kinds of myths that make it difficult to understand. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach effectively. Many non-scientists are unable to grasp the concept, and some scientists even use a definition which confuses it. This is particularly applicable to discussions on the nature of the word.
It is crucial to define the terms used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful way. The site is both a companion for the 2001 series, and it is also a resource on its own. The material is presented in a nested fashion that assists in navigation and orientation.
The site defines terms like common ancestor and gradual process. These terms help to define the nature of evolution as well as its relationship to other scientific concepts. The site gives a comprehensive overview of the ways that evolution has been examined. This information can be used to dispel myths that have been propagated by creationists.
You can also access a glossary that includes terms that are used in evolutionary biology. These terms include:
Adaptation: The tendency of hereditary traits to become more suited to a particular environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less adaptable traits to reproduce and survive.
Common ancestor (also known as common ancestor) is the most recent ancestor that is shared by two or more species. The common ancestor can be identified through analyzing the DNA of those species.
Deoxyribonucleic Acid: A large biological molecular containing the necessary information for 에볼루션게이밍 (sneak a peek at these guys) cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, referred to as chromosomes. Mutations are the cause of new genetic information within cells.
Coevolution is a relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or host and parasite.
Origins
Species (groups which can interbreed) develop by a series of natural variations in their offspring's traits. These changes can be caused by various factors, including natural selection, 에볼루션 무료 바카라 gene drift, and mixing of the gene pool. The development of a new species could take thousands of years, and the process can 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 various animal and plant groups and focuses on major changes in each group's history. It also examines the human evolutionary roots which is particularly important for students to understand.
When Darwin wrote the Origin, 에볼루션 슬롯게임 only a handful of antediluvian human fossils had been found. The famous skullcap, with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just a year before the first edition of the Origin appeared, it is highly unlikely that Darwin had ever heard of it.
While the site is focused on biology, it includes a good deal of information about geology as well as paleontology. The most impressive features on the site are a set of timelines that illustrate the way in which climatic and geological conditions have changed over time, as well as an interactive map of the geographical distribution of some fossil groups listed on the site.
Although the site is a companion to a PBS television series, it also stands on its own as a great source for teachers and students. The site is well-organized and offers clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features on the museum's website. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly, there are links to John Endler's experiments using Guppies that demonstrate 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, 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 can examine not only the process and events that occur frequently or over time, but also the relative abundance and distribution of different species of animals in space throughout the geological time.
The site is divided into a variety of pathways to understanding 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 path also explores common misconceptions about evolution as well as the history of evolutionary thought.
Each of the other major sections of the Evolution site is equally well constructed, 에볼루션 슬롯게임 with materials that can be used to support a range of educational levels and pedagogical styles. The site offers a wide array 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 aids in navigation and orientation on the vast website.
For instance the page "Coral Reef Connections" provides an overview of the relationships between corals and their interaction with other organisms. It then narrows down to a single clam that is able to communicate with its neighbours and respond to changes in 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 broad range of topics in evolutionary biology. The material also provides an explanation of the role of natural selection and the concept of phylogenetic analysis which is a key tool for understanding the evolution of changes.
Evolutionary Theory
Evolution is an underlying thread that connects all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life sciences.
One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and breadth in its educational resources. The site features a wealth of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely tied to the world of research science. An animation that introduces the concept of genetics, which links to a page that highlights John Endler's experiments with artificial selection using guppies on native ponds in Trinidad.
The Evolution Library on this website is a vast multimedia library of assets related with evolution. The content is organized into courses that are based on curriculum and follow 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.
A number of important questions remain in the midst of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is particularly relevant for humans' evolution, where it was difficult to reconcile religious beliefs that humans have a distinct position in the universe and a soul with the notion that human beings have innate physical traits were derived from the apes.
In addition, there are a number of ways that evolution could be triggered with natural selection being the most popular theory. Scientists also study other kinds like mutation, genetic drift, and sexual selection.
While many scientific fields of inquiry conflict with the literal interpretations of religious texts evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. Certain religions have reconciled their beliefs to evolution but others haven't.
