Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution persist. Pop science nonsense has led people to think that biologists don't believe in evolution.
This rich website - companion to the PBS series - provides teachers with materials that support evolution education and help avoid the kinds of misconceptions that make it difficult to understand. It's organized in the "bread crumb" format to aid in navigation and orientation.
Definitions
It's not easy to teach evolution well. Many non-scientists are unable to grasp the concept, and some scientists even use a definition which confuses it. This is especially applicable to discussions on the meaning of the word itself.
It is therefore essential to define the terms used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful way. The site serves as a companion for the 2001 series, and also a resource on its own. The information is presented in an organized manner that makes it simpler to navigate and understand.
The site defines terms such as common ancestor and gradual process. These terms help frame the nature of evolution and its relation to other concepts in science. The website provides a summary of the way that evolution has been examined. This information can help dispel the myths that are created by the creationists.
It is also possible to find the glossary of terms 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 happens when organisms that have better-adapted traits are more likely survive and reproduce than those with less adaptable traits.
Common ancestor (also called common ancestor) is the most recent ancestor that is shared by two or more species. The common ancestor can be identified by analyzing the DNA of the species.
Deoxyribonucleic acid: A huge biological molecule that contains the information necessary for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, called chromosomes. Mutations are the source of new genetic information in cells.
Coevolution is a relationship between two species, where the evolution of one species influence evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey or host and parasite.
Origins
Species (groups of individuals who can interbreed) change through a series of natural changes in the characteristics 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, such as changes in the climate or competition for food or habitat can slow or speed up the process.
The Evolution site follows the evolution of various groups of animals and plants, focusing on major transitions in each group's history. It also examines the evolution of humans and is a subject that is particularly important for students.
Darwin's Origin was written in 1859, when only a few antediluvian fossils of humans had been found. The famous skullcap, with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. 에볼루션바카라사이트 is now recognized as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was published in 1858, a year after the first edition of The Origin. Origin.
The site is mostly a biology site however, it also has many details on geology and paleontology. The Web site has a number of features that are particularly impressive, such as 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.
While the site is a companion piece to a PBS television series however, it can stand on its own as a great resource for teachers and students. The site is well-organized and has clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These links make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are 에볼루션카지노 to John Endler’s experiments with guppies that illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology is the study of these creatures within their geological context is a superior method of study over the current observational or experimental methods of studying evolutionary phenomena. In addition to studying processes and events that take place regularly or over a lengthy period of time, paleobiology can be used to study the diversity of groups of organisms and their distribution throughout geological time.
The site is divided into different options to learn about evolution. One of the paths, "Evolution 101," takes the viewer through the nature and evidence of evolution. The course also focuses on misconceptions about evolution and also the history of evolutionary thinking.
Each of the main sections of the Evolution website is equally well-developed, and includes materials that are suited to a variety of levels of curriculum and teaching methods. In addition to the general textual content, the site offers an array of multimedia and interactive resources, such as video clips, animations, and virtual labs. 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" gives a brief overview of coral relationships and their interaction with other organisms. It then narrows down to a single clam that can communicate with its neighbors and react to changes in water conditions that take place at the level of the reef. This page, along with the other multidisciplinary interactive and multimedia pages provides an excellent introduction to a variety of topics in evolutionary biology. The material includes an explanation of the importance of natural selection and the concept of phylogenetics which is a crucial method for understanding the evolution of changes.
Evolutionary Theory
For biology students evolution is a crucial thread that connects all the branches of the field. A wide selection of resources helps teachers teach evolution across the life science disciplines.
One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that provides depth and broadness in terms of educational resources. The site offers a range of interactive learning modules. It also has a "bread crumb structure" that helps students move away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely related to the worlds of research science. For example, an animation introducing the notion of genetic inheritance leads to a page highlighting John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad.
The Evolution Library on this website contains a large 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 goals set forth in biology standards. It contains seven videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD.
A variety of crucial questions remain at the heart of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is especially true for the evolution of humans, where it was difficult to reconcile religious beliefs that held that humanity has a unique place in creation and a soul with the idea that innate physical traits evolved from apes.
There are also a number of other ways evolution can take place and natural selection being the most well-known theory. However, scientists also study other types of evolution such as mutation, genetic drift, and sexual selection, among other things.
While many fields of scientific inquiry conflict with literal interpretations of religious texts Evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, others haven't.
