Is Evolution Site As Vital As Everyone Says
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution remain. People who have absorbed pop science nonsense often assume that biologists claim they don't believe in evolution.
This rich Web site - companion to the PBS series - provides teachers with materials that support evolution education and avoid the kinds of misconceptions that undermine it. It's laid out in the "bread crumb" format to facilitate navigation and orientation.
Definitions
It's not easy to properly teach evolution. It is often misunderstood by non-scientists and even scientists use definitions that confuse the issue. This is especially relevant when discussing the meaning of the words themselves.
It is therefore important to define the terms used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient manner. The site serves as an accompanying site for the 2001 series, but also a resource on its own. The material is presented in a nested fashion that assists in navigation and orientation.
The site defines terms such as common ancestor and gradual process. These terms help to define the nature and significance of evolution to other concepts in science. The site provides an overview of the way in which evolution has been tested. This information can be used to dispel myths that have been propagated by the creationists.
You can also access a glossary that contains terms used in evolutionary biology. These terms include:
The process of adaptation is the tendency of hereditary traits to become more suitable to their environment. 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 adapted characteristics.
Common ancestor: The most recent common ancestor of two or 무료 에볼루션게이밍 (warner-Langballe-2.thoughtlanes.Net) more species. By analyzing DNA from these species, it is possible to determine the common ancestor.
Deoxyribonucleic acid: A massive biological molecule that holds the 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: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution are the interactions between predator and prey, or parasite and 에볼루션 바카라 (wiki.Gta-Zona.ru) host.
Origins
Species (groups of individuals who can interbreed) develop through a series of natural changes in the characteristics of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental circumstances, 에볼루션게이밍 such as changes in the climate or competition for food and habitat can impede or accelerate the process.
The Evolution site traces the emergence of a variety of groups of animals and plants over time and focuses on the most significant transitions that occurred in the history of each group. It also explores the evolutionary origin of humans which is especially important for students to know.
Darwin's Origin was written in 1859, when only a handful of antediluvian fossils of humans were discovered. The skullcap that is famous, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was one year before the first edition of the Origin was published, it's highly unlikely that Darwin had seen or heard of it.
The site is mostly one of biology, but it also contains a lot of information on paleontology and 에볼루션 무료 바카라 geology. The most impressive features of the website are a series of timelines which show the way in which climatic and geological conditions have changed over time, and a map of the distribution of a few fossil groups that are featured on the site.
While the site is a companion to a PBS television show however, it can stand on its own as an excellent resource for teachers and students. The site is well-organized and offers clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's support) and 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 hyperlinks to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and has a number of advantages over the current observational and experimental methods in its exploration of evolutionary phenomena. In addition to exploring the processes and events that happen frequently or over a long period of time, paleobiology allows to examine the diversity of kinds of organisms as well as their distribution throughout the geological time.
The website is divided into several options to learn about evolution. One of these paths, "Evolution 101," walks the reader through the evolution of nature and the evidence of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution theory's history.
Each of the other main sections of the Evolution site is similarly created, with resources that support a variety of different pedagogical levels and curriculum levels. In addition to the general textual content, the site features an array of interactive and multimedia resources like video clips, animations, and virtual labs. The breadcrumb-like structure of the content aids in navigation and orientation on the large Web site.
The page "Coral Reef Connections" For instance, it gives a brief overview of the relationships between corals and their interactions with other organisms, and then zooms in on a single clam, which can communicate with its neighbors and respond to changes in conditions of the water at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to a variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection and the concept phylogenetics analysis as a key tool for understanding evolutionary change.
Evolutionary Theory
Evolution is a common thread that connects all branches of biology. A rich collection supports teaching evolution across the life science disciplines.
One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that provides the depth and the broadness in terms of educational resources. The site has a wide array of interactive learning modules. It also features an embedded "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. For instance an animation that introduces the notion of genetic inheritance leads to a page highlighting John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.
Another resource that is worth mentioning is the Evolution Library on this web website, which includes an extensive collection of multimedia items connected to evolution. The content is organized into curriculum-based paths that parallel the learning objectives set out in the biology standards. It contains seven videos designed for use in classrooms. They can be streamed or purchased as DVDs.
Evolutionary biology is still an area of study that poses many important questions, including the causes of evolution and how quickly it occurs. This is especially relevant to human evolution, where it has been difficult to reconcile the notion that the innate physical characteristics of humans derived from apes with religious beliefs that claim that humans are unique among living things and has an exclusive place in the creation with a soul.
In addition, there are a number of ways in which evolution could be triggered and 무료 에볼루션 natural selection is the most widely accepted theory. Scientists also study other types like mutation, genetic drift, and sexual selection.
While many scientific fields of study conflict with literal interpretations in religious texts, the concept of evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, while others haven't.
