10 Unexpected Evolution Site Tips
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution persist. Pop science nonsense has led people to believe that biologists aren't believers in evolution.
This site, a companion to the PBS program, provides teachers with materials which support evolution education while avoiding the types of misconceptions that can undermine it. It's laid out in a "bread crumb" format to make navigation and orientation easier.
Definitions
Evolution is a complicated and difficult subject matter to teach effectively. It is often misunderstood by non-scientists, 무료에볼루션 바카라사이트 (please click the following article) and even some scientists use a definition that confuses the issue. This is particularly applicable to discussions about the definition of the word itself.
As such, it is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site serves as an accompanying site for the 2001 series, and also a resource of its own. The material is presented in a nested manner that aids navigation and orientation.
The site defines terms such as common ancestor, gradual process and adaptation. These terms help to frame the nature of evolution and its relationship to other concepts in science. The site gives a comprehensive overview of the ways that evolution has been examined. This information can be used to dispel myths that have been propagated by creationists.
It is also possible to get a glossary of terms used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to become better suited to an environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted characteristics to survive and reproduce.
Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified through analyzing the DNA of these species.
Deoxyribonucleic Acid: A massive biological molecular that contains the information needed for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are the basis for new genetic information in cells.
Coevolution is a relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey or host and parasite.
Origins
Species (groups which can interbreed) develop through a series of natural changes in their offspring's traits. Changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The evolution of a new species may take thousands of years and the process can be slowed or increased by environmental conditions such as climate change or the competition for food or habitat.
The Evolution site tracks the development of a number of different species of plants and animals over time and focuses on the most significant changes that took place in the history of each group. It also examines the human evolutionary roots, a topic that is crucial for students to understand.
Darwin's Origin was written in 1859, at a time when only a few antediluvian fossils of humans had been found. The famous skullcap, with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized 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.
The site is mostly an online biology resource however, it also has a lot of information on geology and paleontology. Among the best features of the Web site are a timeline of events that illustrate how geological and climatic conditions have changed over time, as well as a map of the distribution of a few fossil groups that are featured on the site.
The site is a companion to a PBS television series, but it could also be used as a resource by 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 sophisticated elements of the museum Web site. These hyperlinks make it easy to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. In particular there are links to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has produced many species of animals, plants and insects. Paleobiology is the study of these creatures within their geological context and has numerous advantages over modern observational and experimental methods of examining evolutionary processes. Paleobiology focuses on not just the processes and events that occur regularly or over time, but also the relative abundance and distribution of various animal groups across geological time.
The website is divided into various routes that can be taken to learn about evolution. One of these paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The course also focuses on misconceptions about evolution, as well as the history of evolutionary thought.
Each of the main sections on the Evolution website is equally well-developed, with materials that support a variety levels of curriculum and teaching methods. In addition to the general textual content, the site offers a wide range of interactive and multimedia resources including videos, animations, and virtual laboratories. The content is laid out in a nested bread crumb fashion that aids navigation and orientation on the Web site.
The page "Coral Reef Connections" For 에볼루션 룰렛 instance, it provides a comprehensive overview of the coral's relationships and their interactions with other organisms and is enlarged to show one clam that can communicate with its neighbours and respond to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great introduction to the many areas of evolutionary biology. The content also includes a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a key method to understand evolutionary change.
Evolutionary Theory
For biology students the concept of evolution is a major thread that connects all the branches of the field. A vast collection of resources helps teachers teach about evolution across all life sciences.
One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of an Web page that provides depth as well as wide range of educational resources. The site has a wide array of interactive learning modules. It also has a nested "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the field of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page that highlights John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.
Another resource that is worth mentioning is the Evolution Library on this Web site, which has an extensive multimedia library of resources related to evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives outlined in the biology standards. It contains seven short videos that are designed for classroom use. These can be streamed or purchased as DVDs.
Evolutionary biology remains an area of study that poses many important questions, such as what triggers evolution and how fast it happens. This is particularly relevant for 에볼루션 바카라 사이트 무료체험 [http://www.sbseng.co.th/webboard/index.php?PHPSESSID=3kajkgperd8ukqeondhnr3gi75&action=profile;u=2928] the evolution of humans where it was a challenge to reconcile religious beliefs that held that humans have a distinct place in the creation and a soul with the notion that our physical traits originated from apes.
There are a myriad of other ways evolution could occur including natural selection, which is the most widely accepted theory. However scientists also study different kinds of evolution like genetic drift, mutation, and sexual selection, among others.
Many fields of inquiry have a conflict with literal interpretations of religious texts, evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, but others haven't.
