15 Amazing Facts About Evolution Site That You Didn't Know
Evolution Site - Teaching About Evolution
Despite the best efforts by biology teachers, there are still misconceptions about the evolution. People who have absorbed popular science myths often assume that biologists claim they do not believe in evolution.
에볼루션 바카라사이트 , which is a complement to the PBS program that provides teachers with resources which support evolution education, while avoiding the kinds of misconceptions that can hinder it. It's laid out in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach effectively. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is particularly true when it comes to debates about the definition of the word itself.
It is crucial to define the terms used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient way. The website is a companion to the series that first aired in 2001, but also functions as an independent resource. The material is presented in a nested manner that aids navigation and orientation.
The site defines terms such as common ancestor and gradual process. These terms help to define the nature and relationship of evolution to other scientific concepts. The site provides an overview of the way the concept of evolution has been examined. This information can help dispel myths created by creationists.
It is also possible to access a glossary of terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of hereditary traits to become more suited to the environment. This is a result of natural selection, which occurs when organisms that are more adaptable characteristics are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor (also called common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of those species.
Deoxyribonucleic Acid: A massive biological molecular that contains 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 the source of new genetic information within cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey, or host and parasite.
Origins
Species (groups of individuals that are able to interbreed) develop through a series of natural changes in the traits of their offspring. These changes are caused by a variety that include natural selection, genetic drift and mixing of gene pools. The development of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food or habitat, can slow or accelerate the process.
The Evolution site tracks the evolution of a variety of species of plants and animals over time and focuses on the most significant shifts that occurred throughout the history of each group. It also examines the evolutionary history of humans, a topic that is crucial for students to understand.
When Darwin wrote the Origin, only a handful of antediluvian human fossils 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. Although the skullcap was not published until 1858, which was a year before the first edition of the Origin was published, it is very unlikely that Darwin had ever heard of it.
The site is mostly an online biology resource, but it also contains lots of information about geology and paleontology. The website has numerous features that are particularly impressive, including an overview of how geological and climate conditions have changed over the course of time. It also includes a map showing the distribution of fossil groups.
The site is a companion for a PBS TV series but it can also be used as an educational resource by 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 assistance) as well as the more specialized features of the museum's website. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are links to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has led to an array of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment and has many advantages over the modern observational and research methods in its exploration of evolutionary processes. In addition to studying processes and events that occur regularly or over a long period of time, paleobiology is able to study the relative abundance of various species of organisms and their distribution in space over the geological time.
The site is divided up into different options to learn about evolution. One of these paths, "Evolution 101," guides the user through the evolution of nature and the evidence of evolution. The path also reveals the most common misconceptions about evolution, as well as the evolution of thought.
Each of the other main sections of the Evolution site is equally well constructed, with materials that can support a variety of curriculum levels and pedagogical styles. In addition to general textual content, the site also has an array of multimedia and interactive content including videos, animations, and virtual labs. The breadcrumb-like structure of the content aids in navigation and orientation on the large website.
The page "Coral Reef Connections" For instance, it gives a brief overview of the relationships between corals and interactions with other organisms and then zooms in on one clam that is able to communicate with its neighbors and respond to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to many topics in evolutionary biology. The content also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is an important tool for understanding the evolution of changes.
Evolutionary Theory
For biology students the concept of evolution is a major thread that weaves together 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 excellent example of an Web site that provides depth and breadth in its educational resources. The site features a wide range of interactive learning modules. It also has a nested "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the field of research science. An animation that introduces the concept of genetics links to a page that highlights John Endler's experiments with artificial selection using guppies on native ponds in Trinidad.
Another useful resource is the Evolution Library on this web site, which contains an extensive collection of multimedia items that are related to evolution. The content is organized into curricula-based paths that correspond to the learning objectives outlined in the standards for biology. It includes seven short videos that are intended for use in the classroom. They are available to stream or purchase as DVDs.
A number of important questions remain in the midst of evolutionary biology, including what triggers evolution and the speed at which it occurs. This is especially true for humans' evolution, where it was difficult to reconcile religious beliefs that held that humanity has a special place in the creation and a soul, with the idea that innate physical traits originated from Apes.
Additionally there are a variety of ways in which evolution could occur and natural selection is 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. While some religions have been able to reconcile their beliefs with the ideas of evolution, others haven't.
