What Is Evolution Site How To Use It
Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, there are still a lot of misconceptions regarding evolution. People who have absorbed popular science myths often assume that biologists claim they do not believe in evolution.
This site, a companion to the PBS program that provides teachers with resources that support the evolution of education, while avoiding the kinds of misconceptions that hinder it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
It is difficult to teach evolution well. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is especially true when it comes to discussions on the definition of the word itself.
It is therefore essential to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful manner. The website is a companion to the show which first aired in 2001, but it can also function as an independent resource. The information is presented in a structured manner that makes it easier to navigate and 에볼루션 comprehend.
The site defines terms such as common ancestor (or common ancestor), gradual process, and adaptation. These terms help to define the nature and significance of evolution to other scientific concepts. The site provides an overview of the ways that evolution has been tested. This information can be used to dispel misconceptions that have been created by the creationists.
It is also possible to get the glossary of terms used in evolutionary biology. These terms include:
Adaptation is the tendency of heritable traits to be better suited to an 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 (also known as common ancestor): The most recent ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of the species.
Deoxyribonucleic acid: A large biological molecule that holds the information necessary for cell replication. The information is contained in a sequence of nucleotides that are strung together to form long chains, called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.
Coevolution: A relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution include the interactions 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 characteristics of their offspring. The changes can be caused by a variety of causes such as natural selection, genetic drift and gene pool mixing. The evolution of a new species can take thousands of years and the process could be slowed or increased by environmental factors like climate change or the competition for food or habitat.
The Evolution site tracks the evolution of a number of different groups of animals and plants over time with a focus on the key shifts that occurred throughout the evolution of each group's history. It also focuses on the human evolutionary roots and humans, a subject that is crucial 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 associated bones found in 1856 at the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just a year before the first edition of the Origin appeared, it is highly unlikely that Darwin had ever heard of it.
The site is primarily an online biology resource however it also includes a lot of information on paleontology and geology. The Web site has several features that are particularly impressive, including an overview of how geological and climate conditions have changed over the course of time. It also has a map showing the distribution of fossil groups.
The site is a companion for a PBS television series, but it can also be used as an educational source for teachers and students. The site is well-organized and offers clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features on the museum's website. These hyperlinks help users move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's research with guppies that illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has resulted in many species of animals, plants and insects. Paleobiology, the study of these creatures in their geological context, has many advantages over the current observational or experimental methods for exploring evolutionary phenomena. Paleobiology can examine not just the processes and events that occur regularly or over time but also the distribution and frequency of various animal groups in space throughout the geological time.
The site is divided into various routes that can be taken to study the subject of evolution. One of these paths, "Evolution 101," takes the viewer through the nature and evidence of evolution. The path also explores common misconceptions about evolution as well as the history of evolutionary thought.
Each of the main sections on the Evolution website is equally well-developed, and includes materials that are suited to a variety of educational levels and teaching styles. The site offers a wide array of interactive and multimedia content, including video clips, animations and virtual laboratories, in addition to its general textual content. The breadcrumb-like arrangement of the content helps with navigation and 에볼루션 바카라 룰렛 (Infozillon.Com) orientation on the massive Web site.
For example, the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interactions with other organisms. Then, 에볼루션 슬롯 it concentrates on a specific clam that can communicate with its neighbours and respond to changes in the water conditions that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great introduction to the many areas of evolutionary biology. The content includes an overview of the significance of natural selectivity and the concept phylogenetics analysis as a key method for understanding the evolution of change.
Evolutionary Theory
For biology students evolution is a crucial thread that connects all branches of the field. A wide selection of resources helps teachers teach evolution across all life science disciplines.
One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both the depth and breadth of its educational resources. The site offers a variety of interactive learning modules. It also has a "bread crumb structure" that helps students move away from the cartoon-like style that is used in Understanding Evolution and onto elements of this vast website that are closely connected to the fields of research science. For instance an animation that explains the idea of genetic inheritance connects to a page highlighting John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.
Another useful resource is the Evolution Library on this web site, which has an extensive collection of multimedia items connected to evolution. The content is organized into curriculum-based paths that parallel the learning objectives outlined in the biology standards. It contains seven short videos specifically designed for use in classrooms. They can be streamed or purchased as DVDs.
Many important questions remain at the heart of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is especially true in the case of human evolution where it was a challenge to reconcile religious beliefs that held 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 variety of other ways in which evolution could occur, with natural selection as the most popular theory. Scientists also study different types such as mutation, genetic drift, and sexual selection.
While many scientific fields of study are in conflict with literal interpretations found in religious texts, evolution biology has been a source of intense controversy and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, but others haven't.
