Evolution Site - Teaching About Evolution
Despite the best efforts by biology teachers, there are still misconceptions about the evolution. People who have been exposed to popular science myths often assume that biologists do not believe in evolution.
This rich Web site - companion to the PBS series offers teachers with resources that promote evolution education and avoids the kinds of misconceptions that undermine it. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
It's difficult to properly teach evolution. It is often misunderstood even by non-scientists, and even scientists have been guilty of using a definition that confuses the issue. This is particularly relevant to discussions on the nature of the word.
It is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient way. The site is a companion site to the show that premiered in 2001, but can also function as an independent resource. The information is presented in a structured manner that makes it simpler to navigate and understand.
The site defines terms like common ancestor, the gradual process, and adaptation. These terms help define the nature and relationship of evolution with other scientific concepts. The site gives a comprehensive overview of the ways the concept of evolution has been examined. This information can help dispel myths created by creationists.
It is also possible to access the glossary of terms used in evolutionary biology. These terms include:
Adaptation is the process of changing heritable traits to be better suited to an environment. This is a result of natural selection, which occurs when organisms that have better adapted characteristics are more likely to survive and reproduce than those with less adapted traits.
Common ancestor: The most recent common ancestor of two or more different 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 necessary for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
Coevolution is the relationship between two species where evolutionary changes of one species influence evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey or the parasite and the host.
Origins
Species (groups which can interbreed), evolve through a series of natural changes in their offspring's traits. 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 conditions, like climate change or competition for food or habitat, can slow or accelerate the process.
The Evolution site follows the evolution of various groups of animals and plants and focuses on major changes in each group's past. It also focuses on 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 found. Among them was the famous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, a year after the publication of the first edition of The Origin. Origin.
While 에볼루션 코리아 is focused on biology, it includes a good deal of information about geology as well as paleontology. Among the best features of the website are a timeline of events which show how geological and climatic conditions have changed over time, and a map of the geographical distribution of some fossil groups that are featured on the site.
The site is a companion to a PBS television series, but it could be used as a source for 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 specialized features of the museum's website. These hyperlinks make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler’s experiments with guppies that illustrate the importance ecology in evolutionary theory.
Diversity
The evolution of life has produced many species of animals, plants and insects. Paleobiology is the study of these creatures in their geological environment offers many advantages over modern observational or experimental methods of studying evolutionary processes. In addition to exploring processes and events that take place regularly or over a long period of time, paleobiology is able to analyze the relative abundance of different kinds of organisms as well as their distribution across the course of geological time.
The site is divided up into various options to study the subject of evolution. One of the paths, "Evolution 101," guides the user through the nature and evidence of evolution. The path also explores misconceptions about evolution, and also the history of evolutionary thought.
Each of the main sections of the Evolution website is equally well-developed, and includes materials that are suited to a variety of levels of curriculum and teaching methods. In 에볼루션 무료체험 to the standard textual content, the site offers a wide range of interactive and multimedia resources like videos, animations, and virtual laboratories. The content is presented in a nested bread crumb fashion that aids navigation and orientation within the large Web site.
The page "Coral Reef Connections", for example, provides an overview of the coral's relationships, their interaction with other organisms, and then zooms in to a single clam, which can communicate with its neighbors and react to changes in water conditions that occur on the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to many topics in evolutionary biology. The material also provides an explanation of the role of natural selection and the concept of phylogenetic analysis which is an important tool in understanding evolutionary changes.
Evolutionary Theory
For biology students the concept of evolution is a major thread that binds all branches of the field. A rich collection supports teaching evolution across the life science disciplines.
One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that provides the depth and breadth of its educational resources. The site has a variety 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 huge site that are more closely tied to the world of research science. An animation that introduces students to the concept of genetics is linked to a page that highlights John Endler's experiments with artificial selection using Guppies in native ponds in Trinidad.
Another resource that is worth mentioning is the Evolution Library on this site, which contains an extensive collection of multimedia resources that are related to evolution. The content is organized according to curriculum-based paths that parallel the learning objectives outlined in biology standards. It includes seven short videos specifically designed for classroom use, which can be streamed for no cost or purchased on DVD.
Many important questions remain at the heart of evolutionary biology, including what causes evolution to occur and how fast it occurs. This is especially applicable to human evolution which has made it difficult to reconcile that the physical characteristics of humans derived from apes and religions that believe that humans are unique among living things and has an exclusive place in the creation. It is soul.
There are a variety of other ways in which evolution can occur and natural selection being the most widely accepted theory. However, scientists also study other kinds of evolution, such as genetic drift, mutation, and sexual selection, among others.
While many fields of scientific study conflict with the literal interpretations of religious texts, evolution biology has been a subject of intense debate and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
