Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, misconceptions persist about evolution. People who have been exposed to popular science myths often assume that biologists claim they 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 undermine it. It's organized in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
It is difficult to teach evolution well. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is particularly true when discussing the meaning of the words themselves.
It is therefore important to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The site serves as an accompanying site for the 2001 series, and also a resource of its own. The material is presented in a way 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 relation to other concepts in science. The website provides a summary of the ways that evolution has been examined. This information can help dispel the myths created by creationists.
It is also possible to access the glossary of terms used in evolutionary biology. These terms include:
Adaptation is the process of changing hereditary 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 latest common ancestor of two or more different species. The common ancestor can be identified by studying the DNA of those species.
Deoxyribonucleic Acid: A huge biological molecular that contains the information required for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the source of new genetic information in cells.
Coevolution is a relationship between two species where evolution of one species influence evolutionary changes in the other. Coevolution is evident through the interaction between predator and prey, or parasites and hosts.
에볼루션 바카라 체험 (groups which can interbreed), evolve through a series of natural changes in their offspring's traits. These changes are caused by a variety that include natural selection, genetic drift, and mixing of gene pools. The evolution of new species could take thousands of years. Environmental conditions, such as changes in the climate or competition for food and habitat can slow or speed up the process.
The Evolution site tracks the evolution of a variety of groups of animals and plants over time with a focus on the key changes that took place in each group's history. It also explores the evolutionary history of humans, a topic that is especially important for students to comprehend.
Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans were discovered. One of them was the infamous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, one year after the first edition of The Origin. Origin.
The site is primarily an online biology resource however, it also has many details on geology and paleontology. The most impressive features of the website are a set of timelines that show the way in which climatic and geological conditions have changed over time, and a map of the geographical distribution of some fossil groups listed on the site.
The site is a companion to the PBS television series, but it can also be used as a resource by teachers and students. The site is well-organized and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features of the museum website. These hyperlinks help users move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies. They illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a 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. In addition to exploring the processes and events that happen regularly or over a lengthy period of time, paleobiology is able to study the relative abundance of various species of organisms and their distribution throughout the course of geological time.
The site is divided up into several options to gain knowledge about evolution. One of the paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The path also reveals the most common misconceptions about evolution, as well as the evolution of thought.
Each of the main sections of the Evolution website is equally well-developed, with materials that can be used to support a variety of levels of curriculum and teaching methods. In addition to general textual content, the site also has an extensive selection of interactive and multimedia resources like 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 instance, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interactions with other organisms, and then is enlarged to show a single clam, which is able communicate with its neighbours and respond to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a broad range of topics in evolutionary biology. The content also includes a discussion on the significance of natural selectivity and the concept of phylogenetics, an important method for understanding the evolution of change.
Evolutionary Theory
For biology students the concept of evolution is a major thread that binds all branches of the field. A wide selection of resources helps teachers teach evolution across all disciplines of life science.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that provides depth as well as wide range of educational resources. The site offers a variety of interactive learning modules. It also features an "bread crumb structure" that allows students to move away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely linked to the realms of research science. 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.
Another useful resource is the Evolution Library on this web website, which includes an extensive multimedia library of assets that are 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 videos that are designed for classroom use. They are available to stream or purchase as DVDs.
Evolutionary biology remains a field of study that poses many important questions, including the causes of evolution and the speed at which it happens. This is especially applicable to human evolution which has made it difficult to reconcile the notion that the physical characteristics of humans were derived from apes and religious beliefs that claim that humans are unique among living things and has an exclusive place in the creation. It is soul.
There are a myriad of other ways evolution could occur, with natural selection as the most widely accepted theory. However scientists also study different kinds of evolution, such as genetic drift, mutation, and sexual selection, among others.
While many scientific fields of inquiry have a conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
