Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution persist. Pop science nonsense has led many people to believe that biologists aren't believers in evolution.
This rich Web site, a companion to the PBS program that provides teachers with resources which support evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's laid out in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
It is difficult to effectively teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition which confuses it. This is particularly true when it comes to discussions about the nature of the word.
It is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. simply click the next website is a companion site to the show which first aired in 2001, but it can also function as an independent resource. The content 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 relationship of evolution to other scientific concepts. The website then provides an overview of how the concept of evolution has been vetted and verified. This information can be used to dispel the myths that have been engendered by creationists.
You can also access a glossary that includes terms that are used in evolutionary biology. These terms include:
Adaptation is the process of changing heritable traits to become better suited to an environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted characteristics 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 determine the common ancestor.
Deoxyribonucleic Acid: A huge biological molecular containing the information required for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
Coevolution is the relationship between two species where evolution of one species influence evolutionary changes of the other. Coevolution is evident in the interaction of predator and prey, or parasites and hosts.
Origins
Species (groups that can interbreed) change through a series of natural changes in their offspring's traits. These changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of a new species may take thousands of years, and the process could be slowed or increased by environmental conditions such as climate change or the competition for food or habitat.
The Evolution site tracks the development of a number of different species of plants and animals over time, focusing on the major changes that took place in each group's history. 에볼루션 슬롯 focuses on the human evolutionary roots, a topic that is especially important for students to comprehend.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. 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 as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year after the first edition of the Origin was published, it's extremely unlikely that Darwin had seen or heard of it.
에볼루션 게이밍 is primarily a biology site, but it also contains lots of information about paleontology and geology. The most impressive features of the website are a set of timelines that illustrate how climatic and geological conditions changed over time, and a map of the geographical distribution of some of the fossil groups featured on the site.
While the site is a companion piece to a PBS television series however, it can stand on its own as a valuable resource for teachers and students. The site is extremely well-organized and offers clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. These links facilitate the transition from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler’s experiments with guppies. They illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has produced a variety of plants, animals and insects. Paleobiology is the study of these creatures in their geological context offers many advantages over the current observational or experimental methods of studying evolutionary phenomena. Paleobiology is able to study not just the processes and events that occur regularly or over time, but also the relative abundance and distribution of different groups of animals in space over the course of the geological time.
The Web 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 scientific process and the evidence supporting the theory of evolution. The path also explores misconceptions about evolution, and the background of evolutionary thought.
Each of the other main sections of the Evolution site is equally created, with resources that can support a variety of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia content, including animations, video clips and virtual laboratories in addition to general textual content. The content is organized in a nested, bread crumb style that facilitates navigation and orientation on the web site.
For instance the page "Coral Reef Connections" provides an overview of coral relationships and their interactions with other organisms. Then, it concentrates on a specific clam that is able to communicate with its neighbors and react to changes in the water conditions at the level of the reef. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to the broad spectrum of topics in evolutionary biology. The information also includes an explanation of the role of natural selection and the concept of phylogenetic analysis, which is an important tool in understanding evolutionary change.
Evolutionary Theory
Evolution is an underlying thread that runs through all branches of biology. A rich collection supports teaching evolution across all life science disciplines.
One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both the depth and the breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also has an embedded "bread crumb" structure that helps students transition 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 students to the concept of genetics is linked to a page about John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.
The Evolution Library on this website contains a large multimedia library of resources that are associated 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 the biology standards. It includes seven short videos specifically designed for use in classrooms, and can be streamed for free or purchased on DVD.
A number of important questions remain in the midst of evolutionary biology, including the factors that trigger evolution and how fast it happens. This is particularly true in the case of human evolution, where it was difficult to reconcile religious beliefs that held that humanity has a unique place in the creation and a soul, with the notion that human beings have innate physical traits evolved from the apes.
Additionally there are a myriad of ways in which evolution could be triggered and natural selection is the most widely accepted theory. Scientists also study other kinds like mutation, genetic drift, and sexual selection.
Many fields of inquiry have a conflict with literal interpretations of the Bible Evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, while others haven't.
