7 Things You d Never Know About Evolution Site
Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, there are still misconceptions about the evolution. People who have taken in pop science nonsense often assume that biologists are saying they don't believe in evolution.
This rich website - companion to the PBS series It provides teachers with materials that support evolution education and help avoid the kinds of misinformation that can hinder it. It's organized in the "bread crumb" format to make navigation and orientation easier.
Definitions
Evolution is a complicated and difficult subject matter to teach well. 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 definition of the word itself.
It is therefore essential to define the terms 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 site to the series that first aired in 2001, but is also an independent resource. The material is presented in a structured manner that makes it simpler to navigate and understand.
The site defines terms like common ancestor and the gradual process. These terms help define the nature and relationship of evolution to other scientific concepts. The site also provides an overview of how the concept of evolution has been tested and validated. This information can be used to dispel misconceptions that have been propagated by the creationists.
It is also possible to access the glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable traits to become better suitable to a particular setting. This is a result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adapted traits to survive and reproduce.
Common ancestor: The latest common ancestor of two or more different species. By analyzing DNA from these species it is possible to identify the common ancestor.
Deoxyribonucleic acid: A huge biological molecule that holds the information necessary for cell replication. The information is stored in nucleotide sequences that are strung into long chains, 에볼루션 바카라 무료에볼루션 바카라 체험; Kexiaoshuang write an article, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
Coevolution: A relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be seen through the interaction between predator and prey, or parasite and hosts.
Origins
Species (groups of individuals that can interbreed) evolve through an array of natural changes in the traits of their offspring. These changes are caused by a variety, including natural selection, genetic drift, and mixing of gene pools. The evolution of new species can take thousands of years. Environmental circumstances, such as climate change or competition for food or habitat can slow or 에볼루션 speed up the process.
The Evolution site tracks the development of a variety of species of plants and 에볼루션 사이트 animals over time with a focus on the key shifts that occurred throughout the evolution of each group's history. It also focuses on human evolution, which is a topic that is particularly important to students.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The skullcap that is famous, along with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap when it was published in 1858, which was a year following the initial edition of The Origin.
While the site is focused on biology, it includes a good deal of information about geology and paleontology. The Web site has numerous aspects that are quite impressive, including an overview of how climate and geological conditions have changed over time. It also has an interactive map that shows the location of fossil groups.
Although the site is a companion piece to a PBS television show, it also stands on its own as a valuable resource for teachers and students. The site is extremely well-organized and has clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum Web site. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are hyperlinks to John Endler's research with guppies that illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has resulted in many species 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 phenomena. Paleobiology focuses on not only the process and events that take place regularly or over time, but also the distribution and frequency of various animal groups in space throughout the geological time.
The site is divided into a variety of ways to learn about evolution, including "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence to support the theory of evolution. The path also explores the most common misconceptions about evolution, as well as the evolution of thought.
Each of the other sections of the Evolution site is equally constructed, with materials that support a variety of educational levels and pedagogical styles. The site offers a wide array of interactive and multimedia content, including videos, animations, and virtual labs as well as general textual content. The breadcrumb-like structure of the content assists with navigation and orientation on the large Web site.
For example the page "Coral Reef Connections" provides an overview of coral relationships and their interactions with other organisms. Then, it zooms in on a single clam that can communicate with its neighbors and react to changes in water conditions that take place at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a broad variety of topics in evolutionary biology. The material includes a discussion on the importance of natural selection and the concept of phylogenetics which is a crucial tool for understanding evolutionary changes.
Evolutionary Theory
For biology students evolution is a crucial thread that weaves together all the branches of the field. A rich collection supports teaching evolution across all disciplines of life science.
One resource, which is 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 wide array of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the field of research science. An animation that introduces the concept of genetics, which links to a page that highlights John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.
The Evolution Library on this website is a vast multimedia library of assets related to evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning objectives set out in biology standards. It contains seven videos designed for classroom use. They are available to stream or purchase as DVDs.
Evolutionary biology remains an area of study with a lot of important questions, including what causes evolution and the speed at which it takes place. This is particularly true in the case of human evolution where it was a challenge to reconcile religious beliefs that held that humanity has a special position in the universe and a soul with the notion that human beings have innate physical traits were derived from the apes.
Additionally, there are a number of ways in which evolution could be triggered and natural selection is the most widely accepted theory. However scientists also study different kinds of evolution, such as mutation, genetic drift, and sexual selection, among others.
While many fields of scientific inquiry conflict with literal interpretations of the Bible evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the theories of evolution, other religions aren't.
