Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, there are still misconceptions about the evolution. Pop science nonsense has led many people to believe that biologists aren't believers in evolution.
This rich website - companion to the PBS series It provides teachers with materials that support evolution education and avoid the kinds of misconceptions that hinder it. It's laid out in the "bread crumb" format to aid in navigation and orientation.
Definitions
It is difficult to properly teach evolution. Many non-scientists are unable to grasp the concept, and some scientists even use a definition which confuses it. This is especially applicable to debates about the meaning of the word itself.
It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. The site is both a companion for the 2001 series, but also a resource of its own. The content is presented in a nested manner that aids navigation and orientation.
The site defines terms such as common ancestor, gradual process and so on. These terms help to define the nature of evolution and its relationship to evolution with other scientific concepts. The site also provides an overview of how the concept of evolution has been tested and confirmed. This information can help dispel myths created by creationists.
You can also access a glossary that contains terms that are used in evolutionary biology. These terms include:
Adaptation: The tendency of heritable characteristics to become more adaptable to a specific environment. This is the result of natural selection, which occurs when organisms that have better adapted traits are more likely survive and reproduce than those with less adaptable characteristics.
Common ancestor: The most recent common ancestor of two or more species. The common ancestor can be identified through analyzing the DNA of the species.
Deoxyribonucleic acid: A massive biological molecule that contains the information required for cell replication. The information is stored in nucleotide sequences, 에볼루션 코리아 which are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
Coevolution is a relation between two species, where the evolutionary changes of one species are influenced evolutionary changes in the other. Coevolution is evident through the interaction between predator and prey, or parasite and hosts.
Origins
Species (groups that can interbreed) develop by a series of natural variations in their offspring's traits. Changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, like climate changes or competition for food or habitat, can slow or accelerate the process.
The Evolution site follows the evolution of various species of plants and animals with a focus on major changes in each group's past. It also examines the evolution of humans, which is a topic that is particularly important to students.
Darwin's Origin was written in 1859, at a time when only a few antediluvian fossils of humans had been found. The most famous among them was the skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, 에볼루션 카지노 which was first published in 1858, 에볼루션카지노 a year following the initial edition of The Origin.
While the site is focused on biology, it also contains a wealth of information about geology and paleontology. The website has numerous features that are especially impressive, including a timeline of how geological and climate conditions have changed over the course of time. It also has an interactive map that shows the location of fossil groups.
The site is a companion to a PBS television series, but it can also be used as an educational source for teachers and students. The site is well-organized and offers clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These links make it easier to move from the cartoon style of 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 on Earth has produced a diversity of animals, plants, and insects. Paleobiology is the study of these creatures within their geological context and has a number of advantages over modern observational and experimental methods in its exploration of evolutionary processes. Paleobiology focuses on not only the process and events that happen regularly or over time but also the relative abundance and distribution of various animal groups in space throughout geological time.
The website is divided into several options to gain knowledge about evolution. One of these paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The course also focuses on 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, and includes materials that are suited to a variety of educational levels and teaching styles. The site includes a variety of multimedia and interactive resources that include animations, video clips and virtual labs as well as general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the large web site.
The page "Coral Reef Connections", for example, gives a brief overview of the coral's relationships, their interaction with other organisms and is enlarged to show one clam, which can communicate with its neighbors and react to changes in conditions of the water at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to the broad variety of 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 for understanding the evolution of 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 all life science disciplines.
One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that offers both the depth and breadth of its educational resources. The site has a wide array of interactive learning modules. It also has a nested "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the field of research science. Animation that introduces the concept of genetics is linked to a page highlighting John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.
Another resource that is worth mentioning is the Evolution Library on this website, which includes an extensive library of multimedia assets connected to evolution. The content is organized into curricula-based paths that correspond to the learning goals set forth in the biology standards. It includes seven short videos that are intended for use in the classroom. They can be streamed or purchased as DVDs.
Evolutionary biology remains a field of study that has many important questions, such as what causes evolution and the speed at which it happens. This is especially true for humans' evolution where it was a challenge to reconcile religious beliefs that humanity has a special position in the universe and a soul with the idea that innate physical traits originated from apes.
There are a variety of other ways in which evolution can occur, 무료에볼루션 with natural selection as the most popular theory. Scientists also study other types like mutation, genetic drift and sexual selection.
While many scientific fields of inquiry have a conflict with the literal interpretations of religious texts evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, while others haven't.
