7 Things You ve Never Known About Evolution Site
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions persist about evolution. Pop science nonsense has led people to believe that biologists don't believe evolution.
This site, a companion to the PBS program that provides teachers with resources which support evolution education, while avoiding the kinds of misconceptions which make it difficult to understand. It's laid out in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
It's difficult to effectively teach evolution. It is often misunderstood even by non-scientists, and even scientists are guilty of using an interpretation that is confusing the issue. This is particularly relevant when discussing the meaning of the words themselves.
Therefore, it is crucial to define the terms used in evolutionary biology. Understanding Evolution's website does this in a straightforward and useful manner. The site is both a companion for the 2001 series, and also a resource on its own. The material is presented in a nested fashion that aids navigation and orientation.
The site defines terms like common ancestor, the gradual process, and adaptation. These terms help to frame the nature of evolution and its relationship to other concepts in science. The site also 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 engendered by creationists.
You can also consult a glossary that contains terms that are used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable traits to become better suitable to a particular setting. This is a result of natural selection. Organisms with better-adapted traits are more likely than those with less-adapted traits to reproduce and survive.
Common ancestor (also called common ancestor): The most recent ancestor shared by two or more species. By analyzing DNA from these species, it is possible to determine the common ancestor.
Deoxyribonucleic Acid: A huge biological molecular that contains the information needed for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, called chromosomes. Mutations are the cause of new genetic information within cells.
Coevolution: A relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution are the interactions between predator and prey, or 에볼루션 바카라 무료체험 무료 바카라 에볼루션 (Www.metooo.Es) host and parasite.
Origins
Species (groups of individuals that are able to interbreed) evolve through a series of natural changes in the characteristics of their offspring. Changes can be caused by numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of a new species could take thousands of years and the process can be slowed down or speeded up due to environmental conditions, such as climate change or competition for food or habitat.
The Evolution site tracks through time the evolution of different groups of animals and plants, focusing on major transitions within each group's past. It also examines the human evolutionary roots and humans, a subject that is especially important for students to understand.
When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. Among them was the famous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year before the first edition of the Origin was published, it is extremely unlikely that Darwin had heard or seen of it.
While the site focuses on biology, it also contains a wealth of information about geology as well as paleontology. The most impressive features on the site are a timeline of events that illustrate how climatic and geological conditions changed over time, and an outline of the distribution of some fossil groups listed on the site.
While the site is a companion to a PBS television show however, it can stand on its own as a great source for teachers and students. The site is well-organized and offers easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features of the museum website. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies. They illustrate the importance ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a variety of animals, plants, and insects. Paleobiology is the study of these creatures in their natural environment and has a number of advantages over modern observational and experimental methods in its exploration of evolutionary phenomena. In addition to examining the processes and events that happen regularly or over a lengthy period of time, paleobiology is able to analyze the relative abundance of different groups of organisms and their distribution throughout geological time.
The Web site is divided into a variety of pathways to understanding evolution that include "Evolution 101," which takes the viewer on a liner path through the scientific process and the evidence that supports the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the history of evolutionary thought.
Each of the other main sections of the Evolution site is equally well developed, with materials that support a variety of curriculum levels and pedagogical styles. The site has a range of interactive and multimedia content, including videos, animations, and virtual laboratories, in addition to its general textual content. The content is presented in a nested bread crumb style that facilitates navigation and orientation within the large Web site.
For instance the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interaction with other organisms, then narrows down to a single clam that is able to communicate with its neighbors and react to changes in water conditions that take place at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a wide variety of topics in evolutionary biology. The material also provides an overview of the importance of natural selection and the concept of phylogenetic analysis, which is a key tool in understanding evolutionary changes.
Evolutionary Theory
Evolution is an underlying thread that connects all branches of biology. A vast collection of resources supports teaching about evolution across all life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and breadth in its educational resources. The site offers a range of interactive learning modules. It also features a "bread crumb structure" that allows students to move away from the cartoon style of Understanding Evolution and onto elements on this large website more closely related to the worlds of research science. An animation that introduces the concept of genetics, which links to a page highlighting John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad.
Another resource that is worth mentioning is the Evolution Library on this Web site, which has an extensive collection of multimedia assets related to evolution. The content is organized into curricula-based paths that correspond to the learning goals set forth in the standards for 에볼루션 코리아 (Www.Medflyfish.Com) biology. It contains seven short videos specifically designed for classroom use. These are available to stream or purchase as DVDs.
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 human evolution, where it has been difficult to reconcile the notion that the physical characteristics of humans derived from apes, and the religions that believe that humans are unique among living things and holds a a special place in creation. It is soul.
There are also a number of other ways evolution can take place including natural selection, which is the most popular theory. Scientists also study different types like mutation, genetic drift and sexual selection.
While many scientific fields of inquiry conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, other religions haven't.
