15 Startling Facts About Evolution Site You ve Never Known
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, there are still a lot of misconceptions about evolution. People who have absorbed the nonsense of pop science often believe that biologists are saying they do not believe in evolution.
This rich Web site, a companion to the PBS program, provides teachers with materials which support evolution education while avoiding the types of misconceptions that can undermine it. It's organized in the "bread crumb" format to make navigation and orientation easier.
Definitions
Evolution is a complicated and difficult subject matter to teach effectively. It is often misunderstood even by non-scientists, and even some scientists are guilty of using definitions that confuse the issue. This is especially relevant when it comes to the definition of the words.
As such, it is essential to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The site serves as a companion for the 2001 series, but also a resource of its own. The material is presented in a nested manner that aids navigation and orientation.
The site defines terms like common ancestor, 에볼루션 코리아 사이트 - navigate to this website, gradual process, and adaptation. These terms help frame the nature of evolution and its relationship to other concepts in science. The website then provides an overview of how the concept of evolution has been vetted and confirmed. This information can be used to dispel the myths that have been created by the creationists.
You can also access a glossary that includes terms that are used in evolutionary biology. These terms include:
Adaptation: The tendency for hereditary traits to become more suited to a particular environment. This is a result of natural selection. Organisms that have better-adapted traits are more likely than those with less adapted characteristics to survive and reproduce.
Common ancestor (also called common ancestor): The most recent ancestor that is shared by two or more species. The common ancestor can be identified by analyzing the DNA of the species.
Deoxyribonucleic Acid: A huge biological molecular that holds the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.
Coevolution is the relationship between two species where evolutionary changes of one species are influenced evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or parasite and host.
Origins
Species (groups of individuals who can interbreed) develop through an array of natural changes in the characteristics of their offspring. The changes can be caused by a variety of factors that include natural selection, genetic drift, and mixing of gene pools. The development of a new species can take thousands of years and the process can be slowed down or speeded up by environmental conditions such as climate change or 에볼루션 카지노 사이트 competition for food or habitat.
The Evolution site tracks the development of various animal and plant groups through time with a focus on the key transitions that occurred in the history of each group. It also explores human evolution, which is a topic that is particularly important for students.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The most famous among them was the 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, which was a year before the first edition of the Origin appeared, it is extremely unlikely that Darwin had seen or heard of it.
The site is mostly one of biology, 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 illustrate the way in which climatic and geological conditions changed over time, and a map of the distribution of a few fossil groups listed on the site.
The site is a companion to the PBS TV series but it could also be used as an educational source for teachers and students. The site is well-organized and provides easy 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 hyperlinks facilitate the move 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 experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures within their geological context and has a number of advantages over the current observational and experimental methods for analyzing evolutionary processes. Paleobiology focuses on not only the process and events that take place regularly or over time but also the distribution and frequency of various animal groups across the geological time.
The site is divided into several routes that can be taken to study the subject of evolution. One of the paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also examines myths regarding evolution, and also the history of evolutionary thinking.
Each of the main sections on the Evolution website is equally well-developed, and includes materials that can be used to support a variety of curriculum levels and teaching styles. The site offers a wide array of interactive and multimedia content that include animations, video clips and virtual labs as well as general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the vast website.
The page "Coral Reef Connections" For instance, it provides an overview of coral relationships, 에볼루션게이밍, Delphi.larsbo.org, their interaction with other organisms, and then zooms in to one clam that is able to communicate with its neighbors and react to changes in conditions of the water 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 material includes an explanation of the significance of natural selectivity and the concept phylogenetics analysis, an important tool for understanding evolutionary change.
Evolutionary Theory
Evolution is an underlying thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life science.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that offers both the depth and the broadness in terms of educational resources. The site offers a range of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this massive website that are more closely linked to the field of research science. An animation that introduces students to the concept of genetics, which links to a page that highlights John Endler's experiments with artificial selection using Guppies in native ponds in Trinidad.
The Evolution Library on this website has a huge multimedia library of resources that are associated to evolution. The content is organized into curricula-based pathways that correspond to the learning objectives outlined in biology standards. It contains seven videos specifically designed for classroom use, which can be streamed for no cost or 에볼루션 사이트 purchased on DVD.
Evolutionary biology remains an area of study that poses many important questions to answer, such as the causes of evolution and how fast it takes place. This is particularly relevant for humans' evolution which was a challenge to reconcile religious beliefs that held that humanity has a special place in the creation and a soul, with the notion that our physical traits originated from apes.
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 such as genetic drift and 에볼루션코리아 sexual selection.
Many fields of inquiry have a conflict with the literal interpretations of the Bible Evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, while others haven't.
