Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, there are still a lot of misconceptions about the evolution. Pop science nonsense has led people to believe that biologists aren't believers in evolution.
This rich website - companion to the PBS series - provides teachers with materials which support evolution education and avoids the kinds of misinformation that can make it difficult to understand. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
It is difficult to properly teach evolution. People who are not scientists often have a difficult time understanding the subject, and some scientists even use a definition that confuses it. This is particularly relevant to debates about the definition of the word itself.
It is crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful way. The site is both a companion for the 2001 series, but also a resource of its own. The material is presented in a way that assists in navigation and orientation.
The site defines terms such as common ancestor (or common ancestor), gradual process, and adaptation. These terms help frame the nature of evolution as well as its relation to other scientific concepts. The website provides a summary of the manner that evolution has been tested. This information can help dispel myths created by creationists.
It is also possible to access the glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency of hereditary traits to become more suited to a particular environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less adapted traits to survive and reproduce.
Common ancestor: The latest common ancestor of two or more distinct species. The common ancestor can be identified through analyzing the DNA of those species.
Deoxyribonucleic acid: A huge biological molecule that contains information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are the cause of new genetic information in cells.
Coevolution is a relationship between two species in which the evolution of one species influence evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts.
Origins
Species (groups of individuals who can interbreed) evolve through a series of natural changes in the traits of their offspring. These 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 slow or accelerate the process.
The Evolution site traces through time the emergence of various groups of animals and plants, focusing on major transitions in each group's past. It also examines the evolution of humans, which is a topic that is of particular interest to students.
Darwin's Origin was written in 1859, at a time when only a handful of antediluvian fossils of humans had been found. The famous skullcap, with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year after the first edition of the Origin appeared, it is extremely unlikely that Darwin had ever heard of it.
While the site focuses on biology, it also contains a wealth of information about geology and paleontology. One of the most appealing features of the website are a series of timelines that illustrate how geological and climatic conditions changed over time, as well as a map of the distribution of some fossil groups listed on the site.
While the site is a companion to the PBS television show but it also stands on its own as an excellent source for teachers and students. The site is well-organized, and provides clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features of 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. There are links to John Endler's experiments with guppies. They illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology is the study of these creatures within their geological context and has many advantages over modern observational and experimental methods for analyzing evolutionary phenomena. In addition to examining processes and events that take place frequently or over a long period of time, paleobiology can be used to study the relative abundance of various kinds of organisms as well as their distribution across the course of geological time.
에볼루션 바카라 사이트 is divided into a variety of ways to learn about evolution which include "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence supporting the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution theory's history.
Each of the other main sections of the Evolution site is similarly constructed, with materials that can be used to support a range of curriculum levels and pedagogical styles. The site offers a wide array of interactive and multimedia content that include video clips, animations and virtual labs as well as general textual content. The content is presented in a nested bread crumb style that facilitates navigation and orientation within the large web site.
The page "Coral Reef Connections" For instance, it provides an overview of coral relationships and interactions with other organisms and then is enlarged to show a single clam, which is able to communicate with its neighbors and react to changes in the conditions of the water at the reef level. original site , 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 information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is an important tool for understanding the evolution of change.
Evolutionary Theory
For biology students, evolution is a key thread that binds all the branches of the field. A rich collection of resources helps teachers teach about evolution across all life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that provides depth and breadth in its educational resources. The site offers a range of interactive learning modules. It also features an embedded "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the field of research science. For example an animation that introduces the concept of genetic inheritance links to a page that focuses on John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.
Another helpful resource is the Evolution Library on this Web site, which contains an extensive library of multimedia resources connected to evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives set out in the biology standards. It includes seven short videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.
Many important questions remain at the core of evolutionary biology, including what triggers evolution and how fast it happens. This is particularly relevant for the evolution of humans which was a challenge to reconcile religious beliefs that humanity has a special position in the universe and a soul, with the notion that human beings have innate physical traits were derived from apes.
There are also a number of other ways in which evolution can occur, with natural selection as the most popular theory. Scientists also study other types such as mutation, genetic drift and sexual selection.
While many scientific fields of inquiry are in 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, other religions aren't.
