Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution remain. People who have absorbed pop science nonsense often assume that biologists do not believe in evolution.
This site, which is a companion to the PBS series - provides teachers with materials that promote evolution education and avoids the kinds of misinformation that can undermine it. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
Evolution is a complex and difficult subject matter to teach effectively. It is often misunderstood by non-scientists and
무료에볼루션 even some scientists use an interpretation that is confusing the issue. This is particularly true when it comes to discussions about the definition of the word itself.
Therefore,
무료에볼루션 it is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient way. The site is both an accompanying site for the 2001 series, but also a resource on its own. The content is presented in a nested manner which aids navigation and orientation.
The site defines terms such as common ancestor, the gradual process and adaptation. These terms help to define the nature and relationship of evolution with other scientific concepts. The site gives a comprehensive overview of the way that evolution has been examined. This information can be used to dispel myths that have been created by creationists.
You can also access a glossary which contains terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of hereditary traits to become better suited to an environment. This is a result of natural selection, which happens when organisms that are better-adapted traits are more likely to survive and reproduce than those with less adapted characteristics.
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 by studying the DNA of these species.
Deoxyribonucleic Acid: A massive biological molecular containing the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or
에볼루션 게이밍 parasites and hosts.
Origins
Species (groups of individuals that can interbreed) develop through a series of natural changes in the traits of their offspring. Changes can be caused by many factors, such as natural selection, 무료
에볼루션 무료체험 (
Trade-britanica.trade) gene drift, and mixing of the gene pool. The development of a new species may take thousands of years and the process could be slowed or increased by environmental factors like climate change or the competition for food or habitat.
The Evolution site tracks the evolution of various animal and plant groups through time with a focus on the key changes that took place in the evolution of each group's history. It also focuses on the evolutionary history of humans which is especially important for students to comprehend.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, one year following the initial edition of The Origin. 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 Web site are a timeline of events that show how geological and climatic conditions have changed over time and an outline of the geographical distribution of some fossil groups listed on the site.
Although the site is a companion piece to a PBS television series however, it can stand on its own as a valuable source for teachers and students. The site is very well-organized and offers clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. These hyperlinks facilitate the move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are hyperlinks to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has resulted in an array of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment, has many advantages over modern observational or research methods of studying evolutionary processes. Paleobiology focuses on not just the processes and
에볼루션 슬롯 events that occur regularly or over time but also the relative abundance and distribution of various animal groups in space throughout the geological time.
The website is divided into several routes that can be taken to gain knowledge about evolution. One of these paths, "Evolution 101," guides the user through the evolution of nature and the evidence of evolution. The path also explores misconceptions about evolution, and also the history of evolutionary thought.
Each of the main sections on the Evolution website is equally well-developed, with materials that are suited to a variety of levels of curriculum and teaching methods. The site has a range of interactive and multimedia resources which include video clips, animations and virtual laboratories as well as general textual content. The breadcrumb-like structure of the content helps with navigation and orientation on the vast web site.
The page "Coral Reef Connections", for example, gives a brief overview of the relationships between corals and interactions with other organisms and then is enlarged to show one clam, which is able communicate with its neighbours and respond to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to the broad spectrum of topics in evolutionary biology. The content includes an overview of the importance of natural selection and the concept of phylogenetics analysis, an important tool for understanding evolutionary change.
Evolutionary Theory
For biology students evolution is a crucial thread that binds all the branches of the field. A wide selection of resources helps teachers teach evolution across all disciplines of life science.
One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that offers both depth and breadth in its educational resources. The site has a wide array of interactive learning modules. It also features a "bread crumb structure" that allows students to move away from the cartoon style used in Understanding Evolution and onto elements on this site that are more closely related to the fields of research science. An animation that introduces students to the concept of genetics is linked to a page highlighting John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.
