Despite the best efforts of biology educators, there are still a lot of misconceptions regarding evolution. Pop science fiction has led a lot of people to believe that biologists aren't believers in evolution.
This site, which is a complement to the PBS program that provides teachers with resources that promote evolution education, while avoiding the kinds of misconceptions which hinder it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
Evolution is a complicated and difficult subject to teach effectively. Non-scientists often misunderstand the subject and some scientists use a definition that confuses it. This is especially relevant when it comes to the nature of the words themselves.
As such, it is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The site is a companion site to the show that premiered in 2001, 에볼루션 무료 바카라 but is also an independent resource. The content is presented in a nested manner which aids navigation and orientation.The site defines terms such as common ancestor, the gradual process, and adaptation. These terms help define the nature and relationship of evolution with other scientific concepts. The site gives a comprehensive overview of the ways the concept of evolution has been examined. This information will help to dispel the myths that are created by the creationists.
You can also access a glossary that includes terms used in evolutionary biology. These terms include:
Adaptation: The tendency of hereditary traits to become more suited to a particular environment. This is due to natural selection, which happens when organisms that have more adaptable traits are more likely to survive and reproduce than those with less adaptable traits.
Common ancestor: The latest common ancestor of two or more distinct species. By analyzing the DNA from these species, it is possible to determine the common ancestor.
Deoxyribonucleic acid: A huge biological molecule that contains information necessary for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are the cause of new genetic information in cells.
Coevolution is the relationship between two species in which the evolution of one species are influenced evolutionary changes of the other. Examples of coevolution include the interactions between predator and prey, or 에볼루션 바카라 체험 parasite and host.
Origins
Species (groups of individuals who can interbreed) change through an array of natural changes in the traits of their offspring. The changes can be caused by a variety such as natural selection, genetic drift and gene pool mixing. The development of new species can take thousands of years. Environmental conditions, such as climate change or competition for food or habitat can impede or accelerate the process.
The Evolution site follows the emergence of various animal and plant groups and focuses on major changes within each group's past. It also focuses on the human evolutionary roots and humans, a subject that is particularly important for students to know.
Darwin's Origin was published in 1859, at a time when only a handful of antediluvian fossils of human beings had been discovered. One of them was the infamous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was published in 1858, one year following the initial edition of The Origin. Origin.
The site is primarily a biology site, but it also contains a lot of information on geology and paleontology. Among the best features on the site are a timeline of events that show the way in which climatic and geological conditions have changed over time as well as an interactive map of the distribution of a few fossil groups listed on the site.
The site is a companion to a PBS television series, but it could also be used as a source for teachers and students. The site is well-organized and provides clear links to the introductory content of Understanding Evolution (developed under the National Science Foundation's support) and the more specific features of the museum website. These links facilitate the transition from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are hyperlinks to John Endler's research with Guppies that 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, the study of these creatures in their natural environment offers many advantages over modern observational or 에볼루션 바카라사이트 experimental methods for exploring evolutionary phenomena. In addition to examining processes and events that take place regularly or over a lengthy period of time, paleobiology allows to examine the relative abundance of different groups of organisms and their distribution throughout the course of geological time.
The site is divided up into different options to gain knowledge about evolution. One of the paths, "Evolution 101," walks the reader through the evolution of nature and the evidence of evolution. The path also explores the most common misconceptions about evolution, as well as the evolution of thought.
Each of the main sections of the Evolution website is equally well-developed, and includes materials that can be used to support a variety of educational levels and teaching styles. In addition to the standard textual content, the site also has a wide range of interactive and multimedia resources including videos, animations, and virtual labs. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the vast web site.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms and then zooms in to one clam that is able to communicate with its neighbours and respond to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to a variety of topics in evolutionary biology. The content also includes an overview of the significance of natural selectivity and the concept of phylogenetics, an important tool for understanding evolutionary change.
Evolutionary Theory
Evolution is a common thread that is found throughout all branches of biology. A rich collection supports teaching evolution across all disciplines of life science.
One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that provides the depth and breadth of its educational resources. The site has a variety of interactive learning modules. It also features an encased "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. For instance an animation that explains the concept of genetic inheritance links to a page highlighting John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.
Another resource that is worth mentioning is the Evolution Library on this Web site, which contains an extensive collection of multimedia items related to evolution. The contents are organized into courses that are based on curriculum and follow the learning objectives outlined in the standards for 에볼루션 바카라 무료체험 biology. It contains seven videos that are designed for classroom use. They can be viewed online or purchased as DVDs.
Evolutionary biology is still an area of study that has many important questions, including the causes of evolution and how quickly it happens. This is particularly true for human evolution, where it has been difficult to reconcile the idea that the physical traits of humans evolved from apes with religious beliefs that claim that humanity is unique among living things and holds a an enviable place in creation, with soul.
Additionally, there are a number of ways in which evolution could be triggered with natural selection being the most popular theory. However scientists also study different types of evolution such as mutation, genetic drift, and sexual selection, among others.
Many fields of inquiry are in conflict with literal interpretations of religious texts evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, others have not.
