Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution persist. Pop science nonsense has led many people to believe that biologists aren't believers in evolution.
This rich Web site - companion to the PBS series offers teachers with resources which support evolution education and avoid the kinds of myths that hinder it. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complicated and challenging subject to teach effectively. It is often misunderstood by non-scientists and even scientists use a definition that confuses the issue. This is especially applicable to discussions about the nature of the word.
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 에볼루션 바카라 체험 helpful manner. The site is both an accompanying site for the 2001 series, 에볼루션 바카라사이트 - check over here - but it is also a resource on its own. The information is presented in an organized manner that makes it simpler to navigate and understand.
The site defines terms such as common ancestor (or common ancestor), gradual process, and adaptation. These terms help define the nature of evolution and its relationship to evolution to other scientific concepts. The site also provides an overview of how the concept of evolution has been researched and verified. This information can be used to dispel misconceptions that have been created by creationists.
It is also possible to access a glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency of heritable characteristics to become more adaptable to a specific environment. This is a result of natural selection, which happens when organisms with better adapted traits are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor: The most recent common ancestor of two or more species. By analyzing DNA from these species it is possible to identify the common ancestor.
Deoxyribonucleic Acid: A large biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences which are strung into long chains called chromosomes. Mutations are the basis for new genetic information within cells.
Coevolution is a relation between two species, where the evolution of one species are influenced by evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts.
Origins
Species (groups that can crossbreed) develop by a series of natural variations in their offspring's traits. The changes can be triggered by a variety such as natural selection, genetic drift and gene pool mixing. The evolution of new species could take thousands of years. Environmental conditions, like changes in the climate or competition for food or 에볼루션 룰렛 바카라 무료 (why not try here) habitat can slow or speed up the process.
The Evolution site tracks through time the evolution of various groups of animals and plants and focuses on major changes in each group's past. It also examines the human evolutionary roots, a topic that is particularly important for students to comprehend.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The famous skullcap, with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was published in 1858, a year following the initial edition of The Origin.
The site is primarily an online biology resource however, it also has many details on geology and paleontology. The website has numerous features that are especially impressive, including a timeline of how climate and geological conditions have changed over time. It also features maps that show the locations of fossil groups.
The site is a companion to a PBS television series, but it can be used as a source for teachers and students. The site is well-organized, and provides clear links to the introduction content of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features of the museum's website. These links make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has led to a variety of plants, animals and insects. Paleobiology is the study of these creatures in their natural environment and has a number of advantages over modern observational and experimental methods in its exploration of 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 different groups of animals in space over the course of the geological time.
The website is divided into several paths that can be chosen to gain knowledge about evolution. One of the paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The path also explores misconceptions about evolution and also the history of evolutionary thinking.
Each of the other major sections of the Evolution site is similarly developed, with materials that support a variety of educational levels and pedagogical styles. In addition to general textual content, the site offers an array of multimedia and interactive resources like video clips, animations, and virtual laboratories. The breadcrumb-like structure of the content helps with navigation and orientation on the large Web site.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of the coral's relationships, their interaction with other organisms and zooms in to a single clam, which can communicate with its neighbors and react to changes in the conditions of the water that occur at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, offers a great introduction to the many areas of evolutionary biology. The content also includes an overview of the importance of natural selection and the concept of phylogenetics, an important tool for understanding evolutionary change.
Evolutionary Theory
For biology students evolution is a crucial thread that weaves together all branches of the field. A wide selection of resources helps teachers teach evolution across all life science disciplines.
One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth and broadness in terms of educational resources. The site offers a range of interactive learning modules. It also has a "bread crumb structure" that helps students move away from the cartoon-like style of Understanding Evolution and onto elements on this large website more closely related to the worlds of research science. For example an animation that introduces the notion of genetic inheritance leads to a page highlighting John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.
Another useful resource is the Evolution Library on this Web site, which has an extensive multimedia library of assets that are related to evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives set out in the biology standards. 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, including the factors that trigger evolution and how fast it happens. This is especially true for humans' evolution, where it was difficult 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.
In addition, there are a number of ways in which evolution could occur and natural selection is the most popular theory. Scientists also study other types like mutation, genetic drift, and sexual selection.
Many fields of inquiry are in conflict with literal interpretations of the Bible evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, while others haven't.
