What s The Reason Evolution Site Is Everywhere This Year
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution persist. Pop science nonsense has led many people to think that biologists don't believe in evolution.
This site, which is a complement to the PBS program, provides teachers with materials which support 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 complicated and 에볼루션 difficult subject matter to teach effectively. Non-scientists often misunderstand the subject, 에볼루션 카지노 and some scientists even employ a definition that confuses it. This is particularly applicable to discussions on the nature of the word.
As such, it is crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site is both a companion for the 2001 series, but also a resource on its own. The content is presented in a nested fashion which aids navigation and orientation.
The site defines terms such as common ancestor, gradual process and so on. These terms help define the nature and significance of evolution to other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and confirmed. This information can be used to dispel the myths that have been created by the creationists.
It is also possible to get a glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency of heritable characteristics to become more adaptable to a specific environment. This is due to natural selection. It occurs when organisms with better-adapted traits are more likely survive and reproduce than those with less adaptable characteristics.
Common ancestor (also called common ancestor) The most recent ancestral ancestor shared by two or more species. The common ancestor can be identified by analyzing the DNA of those species.
Deoxyribonucleic Acid: A huge biological molecular that contains the information required for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are the source of new genetic information in cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or parasites and hosts.
Origins
Species (groups of individuals that are able to interbreed) evolve through an array of natural changes in the characteristics of their offspring. These changes can be caused by numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of a new species may take thousands of years and the process could be slowed down or speeded up by environmental conditions such as climate change or the competition for food or habitat.
The Evolution site tracks through time the emergence of various animal and plant groups, focusing on major transitions in each group's history. It also focuses on human evolution, 에볼루션 게이밍 which is a topic that is particularly important for 에볼루션 students.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, one year after the first edition of The Origin. Origin.
While the site focuses on biology, it also contains a wealth of information about geology as well as paleontology. The most impressive features of the Web site are a set of timelines which show how climatic and geological conditions have changed over time, as well as an outline of the geographical distribution of some of the fossil groups featured on the site.
The site is a companion for the PBS TV series but it could be used as a resource for teachers and students. The site is very well-organized and has clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are also links to John Endler's experiments with guppies. They demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has resulted in many species of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment and has numerous advantages over the modern observational and research methods of examining evolutionary phenomena. In addition to studying processes and events that occur regularly or over a lengthy period of time, paleobiology is able to analyze the relative abundance of various groups of organisms and their distribution across geological time.
The website is divided into several paths that can be chosen to learn about evolution. One of the paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The course also focuses on misconceptions about evolution and the background of evolutionary thought.
Each of the other main sections of the Evolution site is similarly developed, with materials that support a variety of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia content, including videos, animations, and virtual laboratories in addition to general textual content. The breadcrumb-like organization of the content helps with navigation and orientation on the massive website.
The page "Coral Reef Connections", for example, provides an overview of the relationships between corals and interactions with other organisms, and then is enlarged to show a single clam, which is able to communicate with its neighbors and respond to changes in water conditions that occur on the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The content includes an overview of the importance of natural selection and the concept of phylogenetics as a key tool to understand evolutionary 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 the life science disciplines.
One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that provides the depth and the breadth in terms of its educational resources. The site features a wealth of interactive learning modules. It also has a "bread crumb structure" that assists students in moving away from the cartoon-like style of Understanding Evolution and onto elements on this site that are more closely linked to the fields of research science. An animation that introduces the concept of genetics is linked 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 contains a large multimedia library of resources that are associated to evolution. The contents are organized into courses that are based on curriculum and follow the learning objectives set out in biology standards. It contains seven videos specifically designed for use in classrooms. These are available to stream or purchase as DVDs.
A variety of crucial questions remain in the midst of evolutionary biology, including the factors that trigger evolution and the speed at which it occurs. This is particularly true for the evolution of humans which was a challenge to reconcile religious beliefs that humanity has a unique place in creation and a soul with the notion that our physical traits evolved from Apes.
There are a variety of other ways in which evolution can occur and natural selection being the most popular theory. However, scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among other things.
While many fields of scientific inquiry conflict with literal interpretations of religious texts evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, others aren't.
