Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science nonsense has led people to believe that biologists don't believe evolution.
This rich website - companion to the PBS series offers teachers with resources that support evolution education and avoid the kinds of myths that undermine it. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
Evolution is a complex and challenging subject to teach effectively. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is particularly relevant when it comes to the meaning of the words themselves.
It is therefore important to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site is a companion to the show that premiered in 2001, but it also functions as an independent resource. The material is presented in a nested fashion that assists in navigation and orientation.
The site defines terms such as common ancestor, gradual process, and adaptation. These terms help to define the nature of evolution and
무료에볼루션 its relationship to evolution to other scientific concepts. The site provides an overview of the manner that evolution has been tested. This information can help dispel the myths created by creationists.
You can also access a glossary which includes terms used in evolutionary biology. These terms include:
Adaptation is the process of changing hereditary traits to become better suited to an environment. This is a result of natural selection. It occurs when organisms that have better adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor (also known as common ancestor) is the most recent ancestor
에볼루션카지노 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 molecular that holds the necessary information for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
Coevolution is a relationship between two species where evolutionary changes of one species influence evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or host and parasite.
Origins
Species (groups of individuals who can interbreed) change through an array 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 evolution of new species could take thousands of years. Environmental conditions, such as climate change or competition for food and habitat can impede or accelerate the process.
The Evolution site tracks the development of various species of plants and animals over time with a focus on the key shifts that occurred throughout the history of each group. It also focuses on human evolution, which is a topic that is of particular interest to students.
Darwin's Origin was published in 1859, at a time when only a handful of antediluvian fossils of human beings 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, which is now known to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was one year before the first edition of the Origin was published, it's highly unlikely that Darwin had heard or seen of it.
The site is primarily a biology site however, it also has lots of information about paleontology and
에볼루션카지노 geology. The Web site has numerous features that are particularly impressive, such as a timeline of the way that climate and geological conditions have changed over time. It also includes a map showing the distribution of fossil groups.
The site is a companion for a PBS television series, but it could also be used as an educational resource for teachers and students. The site is well-organized and offers clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated components of the museum's Web site. These hyperlinks make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are hyperlinks to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geographical context and offers a number of advantages over modern observational and experimental methods for analyzing evolutionary processes. Paleobiology is able to study not only the process and events that happen frequently or over time, but also the distribution and frequency of different groups of animals in space throughout geological time.
The website is divided into various ways to learn about evolution which include "Evolution 101," which takes the user on a linear path through the science of nature and the evidence to support the theory of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thinking.
Each of the other sections of the Evolution site is equally created, with resources that can be used to support a range of different pedagogical levels and curriculum levels. In addition to general textual content, the site offers a wide range of multimedia and interactive resources including video clips, animations, and virtual laboratories. The breadcrumb-like organization of the content helps with navigation and orientation on the large web site.
For example the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms. It then zooms in on a single clam that can communicate with its neighbors and react to changes in the water conditions that occur at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages offers a great introduction to a variety of topics in evolutionary biology. The content also includes an explanation of the role of natural selectivity and the concept of phylogenetics analysis which is a crucial tool for understanding evolutionary change.
Evolutionary Theory
For
바카라 에볼루션 무료체험 (
Bbs.Sanesoft.cn) biology students evolution is a crucial thread that connects all the branches of the field. A wide range of resources helps teachers teach about evolution across the life sciences.
One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both depth and breadth in its educational resources. The site features a wide range of interactive learning modules. It also has a nested "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this massive website that are closer to the field of research science. An animation that introduces the concept of genetics links to a page about John Endler's experiments with artificial selection using guppies on native ponds in Trinidad.
Another resource that is worth mentioning is the Evolution Library on this web site, which has an extensive library of multimedia assets connected to evolution.
