Evolution Site - Teaching About Evolution
Despite the best efforts by biology teachers, there are still misconceptions about evolution. Pop science fiction has led a lot of people to think that biologists don't believe in evolution.
This rich Web site - companion to the PBS series It provides teachers with materials that support evolution education and help avoid the kinds of myths that make it difficult to understand. It's laid out in a "bread crumb" format to aid in navigation and orientation.
Definitions
Evolution is a complex and difficult subject matter to teach effectively. Many non-scientists are unable to grasp the concept and some scientists employ a definition that confuses it. This is particularly applicable to debates about the definition of the word itself.
It is therefore essential to define the terms that are used in evolutionary biology. Understanding 에볼루션 게이밍 helps you define these terms in a straightforward and useful manner. The site is a companion site to the series that first aired in 2001, but can also function as an independent resource. 에볼루션 바카라 체험 is presented in a way that assists in navigation and orientation.
The site defines terms such as common ancestor, gradual process and so on. These terms help frame the nature and relationship of evolution to other scientific concepts. The site also provides an overview of how the concept of evolution has been researched and confirmed. This information can help dispel the myths created by creationists.
It is also possible to find a glossary of terms used in evolutionary biology. 에볼루션 사이트 include:
Adaptation: The tendency of heritable traits to become better suitable to a particular setting. This is the result of natural selection, which happens when organisms with better-adapted traits are more likely to survive and reproduce than those with less adaptable characteristics.
Common ancestor (also called common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of these species.
Deoxyribonucleic acid: A massive biological molecule that holds the information needed for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution is evident through the interaction between predator and prey, or parasites and hosts.
Origins
Species (groups of individuals that can interbreed) change through an array of natural changes in the characteristics of their offspring. These changes can be caused by various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental circumstances, such as climate change or competition for food and habitat can impede or accelerate the process.
The Evolution site traces through time the evolution of different groups of animals and plants and focuses on major changes in each group's history. It also explores the evolutionary history of humans and humans, a subject that is particularly important for students to comprehend.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was published in 1858, one year after the first edition of The Origin. Origin.
The site is mostly a biology site, but it also contains lots of information about geology and paleontology. The site offers numerous features that are particularly impressive, including a timeline of how geological and climate conditions have changed over time. It also includes an interactive map that shows the location of fossil groups.
Although the site is a companion to a PBS television series, it also stands on its own as an excellent resource for teachers and students. The site is well-organized and offers easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features on the museum's website. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly, there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has produced an array of plants, animals and insects. Paleobiology is the study of these creatures in their natural environment offers many advantages over modern observational or research methods for exploring evolutionary processes. In addition to examining the processes and events that happen regularly or over a lengthy period of time, paleobiology allows to analyze the diversity of kinds of organisms as well as their distribution across geological time.
The Web site is divided into a variety of ways to learn about evolution that include "Evolution 101," which takes the user on a linear path through the nature of science and the evidence supporting the theory of evolution. The path also reveals the most common misconceptions about evolution, as well as the history of evolutionary thought.
Each of the main sections of the Evolution website is equally well-developed, and includes materials that can be used to support a variety of levels of curriculum and teaching methods. The site includes a variety of interactive and multimedia content that include videos, animations, and virtual laboratories in addition to general textual content. The content is organized in a nested, bread crumb style that facilitates navigation and orientation within the large Web site.
The page "Coral Reef Connections" For instance, it provides a comprehensive overview of the coral's relationships and interactions with other organisms, and then zooms in to a single clam, which is able communicate with its neighbours and respond to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to the broad variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is a crucial tool for understanding the evolution of change.
Evolutionary Theory
For biology students the concept of evolution is a major thread that binds all the branches of the field. A vast 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 outstanding example of an Web site that provides depth and breadth in its educational resources. The site features a wealth of interactive learning modules. It also features a nested "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely linked to the world of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page highlighting John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.
The Evolution Library on this website contains a large multimedia library of assets related with evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives outlined in biology standards. It contains seven 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 the factors that trigger evolution and the speed at which it occurs. This is especially true for human evolution, where it has been difficult to reconcile the notion that the innate physical characteristics of humans were derived from apes with religions that believe that humans are unique among living things and has an enviable place in creation with soul.
There are a myriad of other ways evolution can occur, with natural selection as the most popular theory. However, scientists also study other kinds of evolution, such as genetic drift, mutation, and sexual selection, among others.
Although many scientific fields of study conflict with literal interpretations found in religious texts, evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, others have not.
