Evolution Site - Teaching About Evolution
Despite the best efforts by biology teachers, there are still misconceptions about evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.
This rich Web site, which is a companion to the PBS program that provides teachers with resources that promote evolution education while avoiding the types of misconceptions that can hinder it. It's laid out in the "bread crumb" format to aid in navigation and orientation.
Definitions
It's difficult to properly teach evolution. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. This is especially relevant when discussing the meaning of the words themselves.
As such, it is essential to define terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. The site is both an accompanying site for the 2001 series, but also a resource on its own. The material is presented in a nested fashion that aids navigation and orientation.
The site defines terms such as common ancestor, 에볼루션 사이트 the gradual process and adaptation. These terms help define the nature and significance of evolution to other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and validated. This information can help dispel myths that are created by the creationists.
It is also possible to access a glossary of terms used in evolutionary biology. These terms include:
Adaptation is the process of changing heritable traits to become better suited to an environment. This is a result of natural selection, which happens when organisms with better adapted characteristics are more likely to survive and reproduce than those with less adaptable traits.
Common ancestor (also known as 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 identify the common ancestor.
Deoxyribonucleic acid: A large biological molecule that holds the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or host and parasite.
Origins
Species (groups that can crossbreed), evolve by a series of natural variations in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. 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 tracks the development of a number of different animal and plant groups through time and focuses on the most significant transitions that occurred in each group's history. It also explores the evolutionary origin of humans and humans, a subject that is especially important for students to comprehend.
When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year after the first edition of the Origin was published, it's very unlikely that Darwin had seen or heard of it.
While the site focuses on biology, it also includes a good deal of information on geology and paleontology. Among the best features of the Web site are a series of timelines that illustrate the way in which climatic and geological conditions have changed over time, as well as a map of the distribution of a few fossil groups that are featured on the site.
The site is a companion for the PBS TV series but it can be used as a resource by teachers and students. The site is extremely well-organized and offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized components of the museum's Web site. These links make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. In particular there are links to John Endler's research with Guppies, which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment and has a number of advantages over the current observational and experimental methods of examining evolutionary phenomena. Paleobiology can examine not only processes and events that take place frequently or over time, but also the distribution and frequency of various animal groups across geological time.
The site is divided into a variety of ways to learn about evolution, including "Evolution 101," which takes the viewer on a line through the scientific process and the evidence that supports the theory of evolution. The path also reveals common misconceptions about evolution and the evolution theory's history.
Each of the main sections of the Evolution website is equally well-designed, with materials that are suited to a variety of curriculum levels and teaching styles. In addition to the general textual content, 에볼루션 바카라 사이트 the site features an array of interactive and multimedia resources like videos, animations, and virtual labs. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation on the web site.
The page "Coral Reef Connections" For instance, it provides a comprehensive overview of the coral's relationships and interactions with other organisms and then is enlarged to show one clam that is able to communicate with its neighbors and respond to changes in water conditions that occur on the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a broad variety of topics in evolutionary biology. The material includes an overview of the significance of natural selectivity and the concept of phylogenetics which is a crucial tool for understanding evolutionary changes.
Evolutionary Theory
For biology students the concept of evolution is a major thread that binds all the branches of the field. A vast collection of resources can help teachers teach about evolution across all life sciences.
One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of an Web site that provides depth as well as breadth in terms of its educational resources. The site has a variety of interactive learning modules. It also features a nested "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely linked to the field of research science. An animation that introduces the concept of genetics, which links to a page that highlights John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.
The Evolution Library on this website is a vast multimedia library of resources that are associated to evolution. The contents are organized into courses that are based on curriculum and 에볼루션 코리아 follow the learning objectives set out in the standards for biology. It contains seven videos specifically designed for use in classrooms. These can be viewed online or purchased as DVDs.
Evolutionary biology remains a field of study that has many important questions to answer, such as what causes evolution and the speed at which it happens. This is particularly relevant for the evolution of humans where it 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.
Additionally, there are a number of ways that evolution can occur and natural selection is the most widely accepted theory. However scientists also study different kinds of evolution like mutation, 에볼루션 카지노 사이트 블랙잭 (Suggested Web site) genetic drift, and sexual selection, among other things.
While many scientific fields of study are in conflict with literal interpretations in religious texts, evolution biology has been the subject of intense debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
