Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science nonsense has led many people to believe that biologists aren't believers in evolution.
This site, which is a companion to the PBS program, provides teachers with materials that promote evolution education while avoiding the types of misconceptions which undermine it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
Evolution is a complicated and challenging subject to teach effectively. Non-scientists often misunderstand the subject and some scientists use a definition that confuses it. 에볼루션사이트 is especially relevant when discussing the nature of the words themselves.
It is crucial to define the terms used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful way. It is a companion for the 2001 series, but also a resource on its own. The material is organized in a manner that makes it simpler to navigate and understand.
The site defines terms like common ancestor (or common ancestor), gradual process and adaptation. These terms help define the nature of evolution and its relationship to evolution with other scientific concepts. The website provides a summary of the ways that evolution has been tested. This information can be used to dispel the myths that have been created by creationists.
It is also possible to get a glossary of terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to become more suitable to their environment. This is the result of natural selection. Organisms with more adaptable traits are more likely than those with less-adapted traits to survive and reproduce.
Common ancestor: The latest common ancestor of two or more distinct species. The common ancestor can be identified by studying the DNA of the species.
Deoxyribonucleic Acid: A large biological molecular containing the information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.
Coevolution is a relation between two species in which the 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 which can interbreed) develop through a series natural changes in their offspring's traits. The causes of these changes are numerous factors, like natural selection, gene drift, and mixing of the gene pool. The development of a new species can take thousands of years and the process could be slowed down or speeded up due to environmental conditions, such as climate change or the competition for food or habitat.
The Evolution site follows the evolution of different animal and plant groups with a focus on major changes in each group's past. It also explores the evolutionary origin of humans which is especially important for students to know.
Darwin's Origin was written in 1859, when only a handful of antediluvian fossils of humans had been found. The skullcap that is famous, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, a year before the first edition of the Origin was published, it is very unlikely that Darwin had seen or heard of it.
While the site focuses on biology, it includes a good deal of information on geology and paleontology. The Web site has numerous features that are especially impressive, such as an overview of how climate and geological conditions have changed over the course of time. It also has an interactive map that shows the location of fossil groups.
While the site is a companion to a PBS television series but it also stands on its own as a valuable resource for teachers and students. The site is extremely 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's web site. These hyperlinks make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. Particularly, 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 led to a variety of animals, plants and insects. Paleobiology, the study of these creatures in their natural environment, has many advantages over the current observational or experimental methods of studying evolutionary phenomena. In addition to examining the processes and events that happen regularly or over a long period of time, paleobiology allows to study the relative abundance of different groups of organisms and their distribution across the geological time.
The site is divided into a variety of ways to learn about evolution, including "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence to support the theory of evolution. The path also examines myths regarding evolution, and the background of evolutionary thinking.
Each of the main sections of the Evolution website is equally well-developed, with materials that are suited to a variety of curriculum levels and teaching styles. In addition to general textual content, the site offers an extensive selection of multimedia and interactive resources like videos, animations, and virtual labs. The content is laid out in a nested bread crumb style that facilitates navigation and orientation within the large web site.
에볼루션 슬롯게임 For instance, it gives a brief overview of coral relationships and their interactions with other organisms and then zooms in to one clam that can communicate with its neighbors and respond to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a wide variety of topics in evolutionary biology. The information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis, which is a crucial tool for understanding the evolution of changes.
Evolutionary Theory
For biology students evolution is a crucial thread that connects all branches of the field. A rich collection supports teaching evolution across all life science disciplines.
One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both depth and a variety of educational resources. The site offers a range of interactive learning modules. It also has a nested "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this massive website that are closer to the field of research science. For example an animation that introduces the notion of genetic inheritance leads to a page that focuses on John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.
The Evolution Library on this website contains a large multimedia library of assets related to evolution. The content is organized according to curricula-based pathways that correspond to the learning objectives outlined in biology standards. It contains seven videos designed specifically for classroom use, which can be streamed for no cost or purchased on DVD.
Evolutionary biology remains an area of study with a lot of important questions to answer, such as the causes of evolution and the speed at which it occurs. This is particularly relevant for humans' evolution where it was a challenge to reconcile religious beliefs that humans have a distinct place in creation and a soul, with the notion that our physical traits were derived from Apes.
Additionally, there are a number of ways in which evolution could be triggered, with natural selection being the most popular theory. Scientists also study other kinds like mutation, genetic drift, and sexual selection.
While many fields of scientific inquiry are in conflict with literal interpretations of religious texts evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, other religions haven't.
