Evolution Site – Teaching About Evolution Despite the best efforts by biology educators, there are still a lot of misconceptions about evolution. People who have absorbed pop science nonsense often assume that biologists are saying they do not believe in evolution. This rich Web site, which is a complement to the PBS program offers teachers resources that support the evolution of education while avoiding the types of misconceptions that hinder it. It's laid out in a “bread crumb” format to facilitate navigation and orientation. Definitions Evolution is a complicated and difficult subject to teach effectively. It is often misunderstood even by non-scientists, and even scientists have been guilty of using a definition that confuses the issue. This is especially true when it comes to debates about the definition of the word itself. It is therefore crucial to define the terms used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient manner. The site is a companion to the series that first aired in 2001, but it can also function as an independent resource. The material is organized in a manner that makes it easier to navigate and understand. The site defines terms like common ancestor and the gradual process. These terms help to define the nature of evolution and its relation to other scientific concepts. The site also provides an overview of how the concept of evolution has been researched and validated. This information can be used to dispel 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: Adaptation: The tendency of hereditary traits to become more adaptable to a specific environment. This is a result of natural selection, which happens when organisms with more adaptable characteristics are more likely to survive and reproduce than those with less adaptable characteristics. Common ancestor: The latest common ancestor of two or more species. By studying the DNA of these species it is possible to identify the common ancestor. Deoxyribonucleic Acid: A large biological molecular that holds the information required for cell replication. 에볼루션게이밍 is stored in a sequence of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells. Coevolution is a relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be seen in the interactions between predator and prey, or parasites and hosts. Origins Species (groups that can crossbreed) change through a series natural changes in their offspring's traits. The changes can be triggered by a variety of causes such as natural selection, genetic drift and gene pool mixing. The evolution of new species can take thousands of years. Environmental conditions, such as climate change or competition for food or habitat, can slow or accelerate the process. The Evolution site tracks the evolution of various species of plants and animals over time and focuses on the most significant transitions that occurred in the history of each group. It also explores the evolutionary history of humans which is crucial for students to comprehend. Darwin's Origin was written in 1859, at a time when only a few antediluvian fossils of humans were discovered. The skullcap that is famous, along with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, a year after the publication of the first edition of The Origin. Origin. While the site is focused on biology, it also contains a wealth of information about geology and paleontology. The most impressive features of the Web site are a timeline of events that illustrate how climatic and geological conditions changed over time, as well as an interactive map of the geographical distribution of some fossil groups that are featured on the site. While the site is a companion to the PBS television show however, it can stand on its own as a great source for teachers and students. The site is extremely well organized and provides clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated components of the museum's Web site. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler’s experiments with guppies that illustrate the importance ecology in evolutionary theory. Diversity The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology is the study of these creatures in their natural environment and has many advantages over the modern observational and research methods for analyzing evolutionary processes. Paleobiology is able to study not only the process and events that occur regularly or over time, but also the relative abundance and distribution of different groups of animals in space throughout the geological time. The site is divided into several optional ways to learn about evolution that include “Evolution 101,” which takes the viewer on a line through the scientific process and the evidence that supports the theory of evolution. The path also explores misconceptions about evolution and the background of evolutionary thinking. Each of the main sections on the Evolution website is equally well-designed, with materials that can be used to support a variety of educational levels and teaching styles. In addition to the standard textual content, the site features a wide range of multimedia and interactive content like video clips, animations, and virtual labs. The content is presented in a nested bread crumb fashion that aids navigation and orientation within the large Web site. The page “Coral Reef Connections”, for example, gives a brief overview of the coral's relationships and their interactions with other organisms, and then is enlarged to show one clam, which can 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 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 and the concept of phylogenetic analysis, which is a crucial tool for understanding the evolution of changes. Evolutionary Theory Evolution is an underlying thread that connects all branches of biology. A rich collection of resources helps teachers teach about evolution across all life sciences. One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that offers both the depth and breadth of its educational resources. The site offers a range of interactive learning modules. It also features a nested “bread crumb” structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this huge site that are closer to the world of research science. Animation that introduces the concept of genetics is linked to a page about John Endler's experiments with artificial selection using guppies on native ponds in Trinidad. Another useful resource is the Evolution Library on this site, which has an extensive library of multimedia resources that are related to evolution. The content is organized into curricula-based paths that correspond to the learning goals set forth in the standards for biology. It includes seven short videos designed specifically for use in the classroom, and can be streamed for free or purchased on DVD. A number of important questions remain at the core of evolutionary biology, such as the factors that trigger evolution and the speed at which it occurs. This is particularly relevant to human evolution, where it's been difficult to reconcile the notion that the innate physical characteristics of humans derived from apes with religious beliefs that claim that humans are unique in the universe and has an exclusive place in the creation. It is a soul. There are a variety of other ways in which evolution can occur including natural selection, which is the most well-known theory. Scientists also study other types such as genetic drift, and sexual selection. Many fields of inquiry conflict with the literal interpretations of the Bible evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, but others haven't.
