Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution persist. People who have been exposed to the nonsense of pop science often believe that biologists do not believe in evolution.
This rich Web site - companion to the PBS series It provides teachers with materials that support evolution education and help avoid the kinds of misinformation that can make it difficult to understand. It's laid out in the "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach well. People who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. This is particularly applicable to discussions on the nature of the word.
It is therefore crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. The site is a companion to the series that first aired in 2001, 에볼루션 게이밍 but it also functions as an independent resource. The material is presented in a way which aids navigation and orientation.
The site defines terms such as common ancestor and gradual process. These terms help to define the nature of evolution and its relationship to evolution to other scientific concepts. The website then provides an overview of how the concept of evolution has been researched and validated. This information can be used to dispel the myths that have been propagated by creationists.
It is also possible to access a glossary of terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of hereditary traits to become better suited to an environment. This is a result of natural selection. Organisms with more adaptable characteristics are more likely than those with less-adapted traits to reproduce and survive.
Common ancestor (also called common ancestor) is the most recent ancestral ancestor shared by two or more species. By studying the DNA of these species, it is possible to determine the common ancestor.
Deoxyribonucleic acid: A large biological molecule that holds the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the basis for new genetic information in cells.
Coevolution is a relationship between two species in which the evolution of one species are influenced by evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasites and hosts.
Origins
Species (groups which can interbreed), evolve by a series of natural variations in the traits of their offspring. The changes can be caused by a variety of causes such as natural selection, genetic drift and mixing of genes. The evolution of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food or habitat can impede or accelerate the process.
The Evolution site traces through time the emergence of various animal and plant groups and focuses on major changes in each group's history. It also explores human evolution as a subject that is of particular interest for students.
Darwin's Origin was written in 1859, when only a handful of antediluvian fossils of humans had been found. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was published in 1858, one year following the initial edition of The Origin.
The site is primarily an online biology resource however it also includes many details on geology and paleontology. The website has several features that are especially impressive, 에볼루션사이트 including an overview of the way that climate and geological conditions have changed over the course of time. It also has a map showing the distribution of fossil groups.
While the site is a companion to a PBS television show however, it can stand on its own as an excellent source for teachers and students. The site is well-organized and provides clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's support) and the more specific features on the museum's website. These hyperlinks help users move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has produced an array of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment is a superior method of study over the current observational or experimental methods of studying evolutionary processes. Paleobiology can examine not just the processes and events that happen frequently or over time, but also the relative abundance and distribution of different species of animals across geological time.
The site is divided into various ways to learn about evolution, including "Evolution 101," which takes the user on a linear path through the scientific process and the evidence supporting the theory of evolution. The path also explores common misconceptions about evolution as well as the history of evolutionary thought.
Each of the main sections of the Evolution website is equally well-developed, and includes materials that support a variety educational levels and teaching styles. The site offers a wide array of interactive and multimedia resources, including videos, animations, and virtual labs, in addition to its general textual content. The content is presented in a nested bread crumb fashion that aids navigation and orientation on the Web site.
The page "Coral Reef Connections" For instance, it gives a brief overview of the coral's relationships and interactions with other organisms and is enlarged to show a single clam, which is able communicate with its neighbours and respond to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a wide variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis, which is a key tool for understanding the evolution of change.
Evolutionary Theory
Evolution is an underlying thread that runs through all branches of biology. A wide range of resources supports teaching about evolution across the life sciences.
One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both depth as well as broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also has an "bread crumb structure" that allows students to move away from the cartoon-like style used in Understanding Evolution and onto elements on this large website more closely linked to the realms of research science. For instance, an animation introducing the concept of genetic inheritance links to a page that focuses on John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad.
Another useful resource is the Evolution Library on this web website, which includes an extensive multimedia library of items connected to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives set out in the biology standards. It contains seven videos designed for classroom use. They can be viewed online or purchased as DVDs.
A variety of crucial questions remain at the heart of evolutionary biology, including what triggers evolution and how fast it happens. This is particularly true in the case of human evolution where it was a challenge to reconcile religious beliefs that humanity has a special place in the creation and a soul, 에볼루션 슬롯 바카라 에볼루션 (homepage) with the notion that our physical traits originated from apes.
Additionally, there are a number of ways that evolution can occur, with natural selection being the most popular theory. Scientists also study other types such as genetic drift and sexual selection.
Although many scientific fields of study conflict with the literal interpretations of religious texts, evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
