Is Evolution Site As Important As Everyone Says
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution persist. People who have absorbed popular science myths often assume that biologists claim they do not believe in evolution.
This rich Web site - companion to the PBS series offers teachers with resources that support evolution education and avoids the kinds of myths that make it difficult to understand. It's organized in the "bread crumb" format to facilitate navigation and orientation.
Definitions
It's difficult to effectively teach evolution. Non-scientists often misunderstand the subject, and some scientists even use a definition that confuses it. This is particularly relevant to debates about the definition of the word itself.
It is crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site is a companion to the show that premiered in 2001, but it can also function as an independent resource. The material is presented in a way that assists in navigation and orientation.
The site defines terms such as common ancestor, the gradual process and adaptation. These terms help frame the nature of evolution and its relationship to other concepts in science. The site then offers an overview of how the concept of evolution has been tested and verified. This information can help dispel the myths created by creationists.
It is also possible to find a glossary of terms used in evolutionary biology. These terms include:
Adaptation is the tendency of hereditary traits to become better suited to an environment. This is the result of natural selection. Organisms with more adaptable traits are more likely than those with less-adapted traits to survive and reproduce.
Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor 에볼루션코리아 can be identified through analyzing the DNA of those species.
Deoxyribonucleic Acid: A large biological molecular containing the necessary information for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
Coevolution is a relationship between two species, where the evolutionary changes of one species are influenced evolutionary changes in the other. Examples of coevolution are the interactions between predator 에볼루션 슬롯 and prey or parasite and host.
Origins
Species (groups that can crossbreed) change through a series of natural changes in the traits of their offspring. Changes can be caused by numerous factors, like 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 changes or competition for food resources and habitat can impede or accelerate the process.
The Evolution site traces through time the emergence of various groups of animals and plants and focuses on major changes in each group's past. It also explores the evolutionary history of humans which is especially important for students to comprehend.
Darwin's Origin was published in 1859, when only a few antediluvian fossils of humans were discovered. Among them was the famous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, which was a year after the publication of the first edition of The Origin.
The site is mostly one of biology however it also includes a lot of information on geology and paleontology. One of the most appealing features of the website are a timeline of events which show how climatic and geological conditions have changed over time as well as a map of the distribution of a few of the fossil groups featured on the site.
While the site is a companion to a PBS television show but it also stands on its own as an excellent resource for teachers and 에볼루션 바카라 students. The site is well-organized and provides easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features on the museum's website. These hyperlinks make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are also links to John Endler's experiments with guppies. They illustrate the importance ecology in evolutionary theory.
Diversity
The evolution of life has led to an array of plants, animals and insects. Paleobiology is the study of these creatures in their geological context offers many advantages over modern observational or research methods of studying evolutionary phenomena. Paleobiology is able to study not only processes and events that take place frequently or over time, but also the relative abundance and distribution of various animal groups in space over the course of the geological time.
The Web site is divided into a variety of ways to learn about evolution, 에볼루션사이트 including "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence that supports the theory of evolution. The course also focuses on common misconceptions about evolution and the history of evolutionary thought.
Each of the other major sections of the Evolution site is equally well created, with resources that support a variety of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia content that include videos, animations, and virtual labs as well as general textual content. The breadcrumb-like arrangement of the content helps with navigation and orientation on the massive web site.
The page "Coral Reef Connections" For instance, it provides an overview of coral relationships and their interactions with other organisms and then is enlarged to show one clam, which can communicate with its neighbors 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, offers a great introduction to the many areas of evolutionary biology. The material includes an explanation of the role of natural selectivity and the concept phylogenetics analysis, an important tool for understanding evolutionary changes.
Evolutionary Theory
For biology students evolution is a crucial thread that weaves together all branches of the field. A rich collection of resources helps teachers teach about evolution across all life sciences.
One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of an Web site that provides depth as well as broadness in terms of educational resources. The site has a variety of interactive learning modules. It also features an embedded "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the world of research science. An animation that introduces the concept of genetics is linked to a page highlighting John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.
The Evolution Library on this website contains a large multimedia library of materials that deal with evolution. The content is organized according to curricula-based paths that correspond to the learning goals set forth in the biology standards. It includes seven short videos specifically designed for use in classrooms, and can be streamed for free or purchased on DVD.
Evolutionary biology is still a field of study that has many important questions, such as the causes of evolution and the speed at which it occurs. This is particularly true for human evolution, where it has been difficult to reconcile that the physical characteristics of humans evolved from apes with religions that believe that humans are unique among living things and has a special place in creation with soul.
There are a variety of other ways in which evolution can occur and natural selection being the most popular theory. Scientists also study other kinds like mutation, genetic drift and sexual selection.
While many fields of scientific study conflict with the literal interpretations of religious texts, evolution biology has been a source of intense debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
