Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, there are still misconceptions about the evolution. 에볼루션 카지노 사이트 has led people to believe that biologists don't believe evolution.
This site, a companion to the PBS program that provides teachers with resources that promote evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complex and difficult subject to teach well. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is especially relevant when discussing the definition of the words.
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 manner. It is a companion for the 2001 series, and also a resource of its own. The content is presented in a nested fashion that assists in navigation and orientation.
The site defines terms such as common ancestor and gradual process. These terms help to define the nature of evolution as well as its relationship to other scientific concepts. The site gives a comprehensive overview of the manner in which evolution has been tested. This information can be used to dispel the myths that have been engendered by the creationists.
It is also possible to find a glossary of terms that are used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable characteristics to become more adaptable to a specific environment. 에볼루션 카지노 사이트 is the result of natural selection. It occurs when organisms with better adapted traits are more likely survive and reproduce than those with less adaptable traits.
Common ancestor (also known as common ancestor): The most recent ancestral ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of those species.
Deoxyribonucleic acid: A massive biological molecule that holds the information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, called 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 by evolutionary changes of the other. Coevolution can be seen through the interaction between predator and prey, or parasites and hosts.
Origins
Species (groups which can interbreed), evolve through a series natural changes in their offspring's traits. The changes can be triggered by a variety of factors that include natural selection, genetic drift, and mixing of genes. The development of a new species could take thousands of years, and the process can be slowed down or speeded up due to environmental conditions, such as climate change or the competition for food or habitat.
The Evolution site traces through time the evolution of various groups of animals and plants with a focus on major changes in each group's past. It also examines the evolutionary origin of humans which is particularly important for students to understand.
Darwin's Origin was published in 1859, when just a few antediluvian fossils of humans had been found. The most famous among them was the skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, which was a year after the first edition of The Origin.
The site is mostly a biology site however, it also has lots of information about paleontology and geology. The site offers several features that are especially impressive, such as the timeline 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 to a PBS TV series but it could also be used as an educational source for teachers and students. The site is well-organized and has clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These links facilitate the transition from the engaging 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, which 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 is the study of these creatures within their natural environment and has many advantages over the current observational and experimental methods in its exploration of evolutionary processes. In addition to exploring the processes and events that happen regularly or over a long period of time, paleobiology allows to analyze the relative abundance of different kinds of organisms as well as their distribution throughout the geological time.
The Web site is divided into a variety of paths to learning evolution, including "Evolution 101," which takes the user on a linear path through the nature of science and the evidence supporting the theory of evolution. The course also focuses on misconceptions about evolution and the background of evolutionary thinking.
Each of the main sections on the Evolution website is equally well-developed, and includes materials that support a variety curriculum levels and teaching styles. The site offers a wide array of interactive and multimedia content that include video clips, animations and virtual labs in addition to general textual content. The content is organized in a nested, bread crumb fashion that aids navigation and orientation on the Web site.
For example, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms. Then, it concentrates on a specific clam that is able to communicate with its neighbors and respond to changes in the water conditions at the level of the reef. 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 a discussion on the significance of natural selectivity and the concept of phylogenetics, an important tool to understand evolutionary change.
Evolutionary Theory
Evolution is a common thread that is found throughout all branches of biology. A rich collection of resources supports teaching about evolution across all life sciences.
One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and a variety of educational resources. 에볼루션카지노 features a wide range of interactive learning modules. It also features an encased "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the field of research science. For instance an animation that introduces the idea of genetic inheritance connects to a page that focuses on John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.
Another useful resource is the Evolution Library on this Web site, which has an extensive library of multimedia items related to evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives outlined in biology standards. It contains seven videos specifically designed for use in the classroom, and can be streamed for no cost or purchased on DVD.
A number of important questions remain in the midst of evolutionary biology, such as what triggers evolution and how fast it happens. This is especially true for human evolution, which has made it difficult to reconcile the notion that the innate physical characteristics of humans derived from apes, and the religions that believe that humanity is unique among living things and holds a an exclusive place in the creation. It is a soul.
Additionally there are a variety of ways that evolution could occur with natural selection being the most popular theory. However scientists also study other types of evolution such as genetic drift, mutation, and sexual selection, among others.
Many fields of inquiry conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, but others haven't.
