Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, there are still a lot of misconceptions regarding evolution. Pop science nonsense has led many people to believe that biologists aren't believers in evolution.
This site, a companion to the PBS program that provides teachers with resources which support evolution education while avoiding the types of misconceptions that make it difficult to understand. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
Evolution is a complicated and difficult subject to teach well. People who are not scientists often have a difficult time understanding the subject, and some scientists even use a definition which confuses it. This is especially relevant to discussions about the nature of the word.
It is therefore important to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. The website is a companion to the show which first aired in 2001, but it also functions as an independent resource. The information is presented in an organized manner that makes it simpler to navigate and understand.
The site defines terms such as common ancestor, gradual process and so on. These terms help to frame the nature of evolution as well as its relationship to other concepts in science. The site gives a comprehensive overview of the manner that evolution has been examined. This information can be used to dispel the myths that have been created by creationists.
It is also possible to access a glossary of terms used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to be more suited to the environment. This is the result of natural selection. Organisms with better-adapted characteristics are more likely than those with less adaptable characteristics to survive and reproduce.
Common ancestor: The most recent common ancestor of two or more species. By analyzing the DNA from these species it is possible to determine the common ancestor.
Deoxyribonucleic acid: A huge biological molecule that holds the information necessary for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be seen in the interaction of predator and prey, or parasites and hosts.
Origins
Species (groups of individuals that are able to interbreed) evolve through natural changes in the traits of their offspring. The changes can be triggered by a variety that include natural selection, genetic drift and mixing of gene pools. The evolution of new species can take thousands of years. Environmental circumstances, such as climate change or competition for food and habitat, can slow or accelerate the process.
The Evolution site tracks through time the emergence of various groups of animals and plants and focuses on major changes in each group's past. It also explores the evolutionary history of humans and humans, a subject that is especially important for students to understand.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The famous skullcap, with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year before the first edition of the Origin was published, it is highly unlikely that Darwin had seen or heard of it.
The site is mostly a biology site however it also includes many details on paleontology and geology. One of the most appealing features of the Web site are a series of timelines that illustrate how climatic and geological conditions have changed over time as well as a map of the geographical distribution of some fossil groups listed on the site.
The site is a companion to a PBS television series, but it can also be used as an educational resource for teachers and students. The site is well-organized, and provides clear links to the introduction content of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features on the museum's website. These hyperlinks facilitate the move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are hyperlinks to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has resulted in an array of plants, animals and insects. Paleobiology, the study of these creatures within their geological context offers many advantages over modern observational or research methods for studying evolutionary phenomena. Paleobiology is able to study not only processes and events that take place frequently or over time, but also the relative abundance and distribution of various animal groups in space over the course of the geological time.
The website is divided into several optional ways to learn about evolution that include "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence to support the theory of evolution. The path also explores misconceptions about evolution, and also the history of evolutionary thinking.
Each of the other sections of the Evolution site is equally well constructed, with materials that support a variety of curriculum levels and pedagogical styles. The site includes a variety of multimedia and interactive resources that include video clips, animations and virtual laboratories, in addition to its general textual content. The breadcrumb-like structure of the content helps with navigation and orientation on the large web site.
The page "Coral Reef Connections", for example, gives a brief overview of the coral's relationships and interactions with other organisms and then zooms in to one clam that can communicate with its neighbors and react to changes in water conditions that occur on the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages gives a good introduction to many topics in evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis which is a key method to understand evolutionary change.
Evolutionary Theory
Evolution is an underlying thread that connects all branches of biology. A vast collection of books helps in teaching evolution across all life science disciplines.
One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both depth and breadth in its educational resources. The site has a variety of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely linked to the field of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page that highlights John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.
discover here on this website is a vast multimedia library of assets related to evolution. The content is organized according to curriculum-based paths that parallel the learning goals established in biology standards. It contains seven short videos designed for classroom use. 에볼루션 카지노 사이트 are available to stream or purchase as DVDs.
A variety of crucial questions remain in the midst of evolutionary biology, such as what triggers evolution and how fast it occurs. This is especially true in the case of human evolution which was a challenge to reconcile religious beliefs that humanity has a unique place in creation and a soul with the notion that human beings have innate physical traits evolved from apes.
There are a myriad of other ways in which evolution could occur, with natural selection as the most well-known theory. However scientists also study different types of evolution such as genetic drift, mutation, and sexual selection, among others.
While many fields of scientific inquiry are in conflict with the literal interpretations of the Bible Evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
