Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science nonsense has led many people to believe that biologists aren't believers in evolution.
This site, which is a companion to the PBS series - provides teachers with materials that promote evolution education and avoid the kinds of myths that hinder it. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
Evolution is a complicated and challenging subject to teach effectively. It is often misunderstood by non-scientists and even scientists are guilty of using definitions that confuse the issue. This is particularly true when discussing the nature of the words themselves.
As such, it is essential to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The site serves as a companion for the 2001 series, and 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 (or common ancestor), gradual process and adaptation. 에볼루션 help frame the nature and relationship of evolution with other scientific concepts. The site gives a comprehensive overview of the ways in which evolution has been examined. This information can be used to dispel misconceptions that have been engendered by creationists.
You can also access a glossary which contains terms used in evolutionary biology. These terms include:
Adaptation: The tendency of heritable traits to become better suited to a particular environment. This is a result of natural selection. Organisms with better-adapted traits are more likely than those with less adaptable characteristics to survive and reproduce.
Common ancestor (also known as common ancestor) The most recent ancestor that is shared by two or more species. The common ancestor can be identified by studying the DNA of those species.
Deoxyribonucleic Acid: A huge biological molecular that holds the information required for cell replication. The information is contained in a sequence of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the cause of new genetic information within cells.
Coevolution is a relationship between two species, where the evolution of one species are influenced evolutionary changes of the other. Examples of coevolution are the interactions between predator and prey or parasite and host.
Origins
Species (groups of individuals that can interbreed) change through a series of natural changes in the traits of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift, and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, like climate change or competition for food or habitat can impede or accelerate the process.
The Evolution site tracks the evolution of various animal and plant groups through time with a focus on the key changes that took place in each group's history. It also examines the evolution of humans and is a subject of particular importance to students.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It 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 heard or seen of it.
에볼루션 바카라 사이트 is primarily an online biology resource however, it also has a lot of information on paleontology and geology. The Web site has several features that are particularly impressive, including an overview of the way that climate and geological conditions have changed over time. It also has a map showing the distribution of fossil groups.
Although the site is a companion to a PBS television show however, it can stand on its own as a great source for teachers and students. The site is well-organized and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features of the museum website. These links make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler’s experiments with guppies, which illustrate the importance ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a variety of plants, animals, and insects. Paleobiology is the study of these creatures within their natural environment and has numerous advantages over modern observational and experimental methods for analyzing evolutionary processes. In addition to studying processes and events that take place regularly or over a lengthy period of time, paleobiology is able to study the diversity of groups of organisms and their distribution across the course of geological time.
The Web site is divided into various pathways to understanding evolution that include "Evolution 101," which takes the user on a linear path through the nature of science and the evidence to support the theory of evolution. The path also explores common misconceptions about evolution as well as the evolution theory's history.
Each of the main sections of the Evolution website is equally well-developed, with materials that support a variety educational levels and teaching styles. In addition to general textual content, the site features a wide range of interactive and multimedia resources including videos, animations, and virtual laboratories. The breadcrumb-like structure of the content helps with navigation and orientation on the massive website.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides an overview of the relationships between corals, their interaction with other organisms, and then zooms in to one clam, which can communicate with its neighbors and respond to changes in the 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 includes an overview of the importance of natural selection and the concept phylogenetics analysis as a key method for understanding the evolution of change.
Evolutionary Theory
Evolution is an underlying thread that runs through all branches of biology. A wide selection of resources helps teachers teach evolution across all disciplines of life science.
One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that provides depth and breadth in its educational resources. The site has a variety of interactive learning modules. It also features a nested "bread crumb" structure that helps students move from the cartoon-like 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 students to the concept of genetics links to a page highlighting 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 materials that deal with evolution. The content is organized into curriculum-based paths that parallel the learning objectives set out in the biology standards. It contains seven short videos specifically intended for use in the classroom. They can be viewed online or purchased as DVDs.
Evolutionary biology remains an area of study that poses many important questions, such as what triggers evolution and how fast it takes place. This is particularly true in the case of human evolution which was a challenge to reconcile religious beliefs that humanity has a unique place in creation and a soul, with the notion that our physical traits were derived from Apes.
There are a variety of other ways in which evolution can occur, with natural selection as the most well-known theory. Scientists also study different types such as mutation, genetic drift and sexual selection.
Although many scientific fields of study are in conflict with literal interpretations found in religious texts, the concept of evolution biology has been a source of intense controversy and opposition from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, while others haven't.
