Say "Yes" To These 5 Evolution Site Tips
Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, there are still a lot of misconceptions about the evolution. Pop science nonsense has led many people to believe that biologists aren't believers in evolution.
This site, a companion to the PBS program offers teachers resources which support evolution education while avoiding the types of misconceptions that hinder it. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
It is difficult to properly teach evolution. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is particularly relevant when it comes to the definition of the words.
Therefore, it is essential to define terms that are used in evolutionary biology. Understanding Evolution's website does this in a straightforward and useful manner. The site serves as an accompaniment to the 2001 series, and also a resource on its own. The material is presented in a way which aids navigation and orientation.
The site defines terms such as common ancestor (or common ancestor), gradual process and adaptation. These terms help frame the nature of evolution as well as its relation to other scientific concepts. The site provides an overview of the manner that evolution has been tested. This information can be used to dispel the myths that have been engendered by the creationists.
You can also consult a glossary that includes terms that are used in evolutionary biology. These terms include:
Adaptation is the tendency of hereditary traits to become more suited to the environment. This is due to natural selection, which occurs when organisms with better-adapted characteristics are more likely to survive and reproduce than those with less adapted traits.
Common ancestor: The latest common ancestor of two or more distinct species. The common ancestor can be identified by analyzing the DNA of these species.
Deoxyribonucleic acid: A massive biological molecule that contains the information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, also known as chromosomes. Mutations are the cause of new genetic information within cells.
Coevolution is a relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be observed through the interaction between predator and prey, or parasites and hosts.
Origins
Species (groups of individuals that can interbreed) develop through natural changes in the characteristics of their offspring. The causes of these changes are various factors, including natural selection, gene drift, and mixing of the gene pool. pop over here of new species can take thousands of years. Environmental conditions, such as climate change or competition for food and habitat can impede or accelerate the process.
The Evolution site traces through time the evolution of different groups of animals and plants, focusing on major transitions in each group's past. It also explores human evolution as a subject that is particularly important to students.
Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of human beings had been discovered. Among them was the famous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, a year following the initial edition of The Origin. Origin.
While the site is focused on biology, it also includes a good deal of information about geology as well as paleontology. The website has several features that are especially impressive, including a timeline of how climate and geological conditions have changed over time. It also has a map showing the distribution of fossil groups.
The site is a companion for the PBS TV series but it could also be used as a source for teachers and students. The site is extremely well-organized and offers clear links between the introduction content 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 engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also links to John Endler's experiments with guppies, which 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 geological context and has numerous advantages over the modern observational and research methods in its exploration of evolutionary phenomena. Paleobiology can examine 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 up into various paths that can be chosen to learn about evolution. One of the paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thought.
Each of the main sections of the Evolution website is equally well-designed, with materials that can be used to support a variety of curriculum levels and teaching styles. The site offers a wide array of multimedia and interactive resources that include video clips, animations and virtual labs in addition to general textual content. The breadcrumb-like arrangement of the content aids in navigation and orientation on the massive website.
The page "Coral Reef Connections", for example, gives a brief overview of the relationships between corals and interactions with other organisms and then zooms in on a single clam, which is able communicate with its neighbours and respond to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a wide range of topics in evolutionary biology. The content also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis, which is a crucial method to understand evolutionary changes.
Evolutionary Theory
For biology students, evolution is a key thread that weaves together all the 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 television show Understanding Evolution is an excellent example of an Web site that provides depth as well as broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also has an embedded "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this huge site that are more closely tied to the world of research science. An animation that introduces the concept of genetics, which links to a page that highlights John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad.
The Evolution Library on this website is a vast multimedia library of assets related with evolution. The content is organized into curriculum-based paths that parallel the learning objectives outlined in the biology standards. It contains seven videos specifically designed for classroom use, which can be streamed for no cost or purchased on DVD.
Evolutionary biology is still a field of study with a lot of important questions to answer, such as what causes evolution and how quickly it takes place. This is particularly applicable to human evolution where it has been difficult to reconcile the notion that the physical characteristics of humans derived from apes and religions that believe that humanity is unique in the universe and has an exclusive place in the creation, with soul.
Additionally there are a myriad of ways that evolution could occur with natural selection being the most popular theory. Scientists also study different types such as genetic drift, and sexual selection.
While visit this site of scientific inquiry are in conflict with the literal interpretations of the Bible evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
