Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, there are still misconceptions about evolution. People who have taken in the nonsense of pop science often believe that biologists are saying they do not believe in evolution.
This rich website - companion to the PBS series offers teachers with resources that support evolution education and help avoid the kinds of myths that make it difficult to understand. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
It's difficult to properly teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition that confuses it. This is especially relevant when discussing the definition of the words.
It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in a straightforward and useful way. It is a companion for the 2001 series, but it is also a resource on its own. The information is presented in a structured manner that makes it simpler to navigate and understand.
The site defines terms like common ancestor, the gradual process and adaptation. These terms help frame the nature and relationship of 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 the myths that have been propagated by creationists.
It is also possible to get a glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency of heritable traits to become better suitable to a particular setting. This is a result of natural selection. 에볼루션게이밍 that have better-adapted characteristics are more likely than those with less-adapted characteristics to survive and reproduce.
Common ancestor: The latest common ancestor of two or more species. By analyzing DNA from these species it is possible to determine the common ancestor.
Deoxyribonucleic Acid: A huge biological molecular that contains the information required for cell replication. The information is stored in nucleotide sequences, which are strung into long chains, referred to as chromosomes. Mutations are the cause of new genetic information within cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be seen through the interaction between predator and prey, or parasites and hosts.
Origins
Species (groups of individuals who can interbreed) change through natural changes in the characteristics of their offspring. The changes can be triggered by a variety of factors that include natural selection, genetic drift and mixing of genes. The development of a new species could take thousands of years and the process may be slowed down or accelerated due to environmental conditions, such as climate change or competition for food or habitat.
The Evolution site traces through time the evolution of various groups of animals and plants, focusing on major transitions within each group's past. It also explores the human evolutionary roots, a topic that is crucial for students to know.
Darwin's Origin was published in 1859, when just a handful of antediluvian fossils of humans were discovered. One of them was the infamous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, one year following the initial edition of The Origin.
While the site is focused on biology, it offers a lot of information about geology as well as paleontology. Among the best features on the site are a timeline of events which show how climatic and geological conditions changed over time, and a map of the distribution of some of the fossil groups featured on the site.
Although the site is a companion piece to the PBS television series however, it can stand on its own as a valuable source for teachers and students. The site is well-organized and provides easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized features of the museum's 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 that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology is the study of these creatures within their geographical context and offers a number of advantages over the current observational and experimental methods for analyzing evolutionary processes. In addition to exploring the processes and events that happen regularly or over a lengthy period of time, paleobiology allows to analyze the relative abundance of various groups of organisms and their distribution across the course of geological time.
The site is divided into a variety of paths to learning evolution, including "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence supporting the theory of evolution. The path also explores the most common misconceptions about evolution, as well as the history of evolutionary thought.
Each of the other major sections of the Evolution site is equally created, with resources that support a variety of educational levels and pedagogical styles. The site has a range of multimedia and interactive resources, including animations, video clips and virtual labs, in addition to its general textual content. The breadcrumb-like organization of the content assists with navigation and orientation on the vast web site.
The page "Coral Reef Connections" For instance, it gives a brief overview of the coral's relationships and interactions with other organisms, and then zooms in to a single clam, which is able to communicate with its neighbors 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 the broad range of topics in evolutionary biology. The information also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is a key tool in understanding evolutionary change.
Evolutionary Theory
Evolution is a common thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach evolution across all disciplines of life sciences.
에볼루션바카라사이트 , the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that offers both depth as well as breadth in terms of its educational resources. 에볼루션바카라사이트 offers a range of interactive learning modules. It also has a "bread crumb structure" that assists students in moving away from the cartoon style that is used in Understanding Evolution and onto elements on this large website more closely linked to the worlds of research science. Animation that introduces the concept of genetics, which links to a page that highlights John Endler's experiments with artificial selection using guppies on native ponds in Trinidad.
Another useful resource is the Evolution Library on this Web site, which has an extensive multimedia library of items that are related to evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in biology standards. It includes seven short videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.
Evolutionary biology is still an area of study that has many important questions, including what triggers evolution and the speed at which it occurs. This is especially relevant to human evolution, where it's been difficult to reconcile the notion that the physical traits of humans evolved from apes with religions that believe that humanity is unique in the universe and has an enviable place in creation. It is a soul.
There are also a number of other ways in which evolution can take place and natural selection being the most well-known theory. Scientists also study different types such as mutation, genetic drift and sexual selection.
While many fields of scientific study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been a source of intense controversy and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, others have not.
