에볼루션 바카라 사이트 - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution remain. Pop science nonsense has led people to believe that biologists don't believe evolution.
This rich Web site - companion to the PBS series - provides teachers with materials that promote evolution education and help avoid the kinds of myths that undermine it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach well. 에볼루션 무료체험 who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. This is especially relevant when discussing the definition of the words.
It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The website is a companion to the series that first aired in 2001, but it also functions as an independent resource. The material is organized in a manner that makes it simpler to navigate and understand.
The site defines terms like common ancestor, gradual process, and adaptation. These terms help frame the nature and relationship of evolution with other scientific concepts. The site also provides an overview of how the concept of evolution has been vetted and verified. This information will help to dispel the myths created by creationists.
It is also possible to get a glossary of terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to be more suited to the environment. This is the result of natural selection, which happens when organisms that have better adapted characteristics are more likely to survive and reproduce than those with less adaptable characteristics.
Common ancestor: The most recent common ancestor of two or more different species. The common ancestor can be identified by analyzing the DNA of those species.
Deoxyribonucleic acid: A massive biological molecule that holds the information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are the source of new genetic information within cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or the parasite and the host.
Origins
Species (groups of individuals that can interbreed) change through a series of natural changes in the characteristics of their offspring. These changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The development of a new species may take thousands of years, and the process can be slowed down or accelerated by environmental conditions such as climate change or the competition for food or habitat.
The Evolution site traces through time the evolution of various animal and plant groups and focuses on major changes in each group's history. It also focuses on human evolution as a subject of particular importance for students.
Darwin's Origin was published in 1859, when only a few antediluvian fossils of human beings had been discovered. The famous skullcap, with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year after the first edition of the Origin was published, it is highly unlikely that Darwin had heard or seen of it.
The site is mostly one of biology however, it also has many details on paleontology and geology. Among the best features of the website are a timeline of events that show the way in which climatic and geological conditions have changed over time as well as an interactive map of the distribution of a few fossil groups listed on the site.
Although the site is a companion piece to a PBS television show but it also stands on its own as a valuable resource for teachers and students. The site is well-organized and offers easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features of the museum website. These hyperlinks make it easy to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are links to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures within their natural environment and has numerous advantages over the current observational and experimental methods of examining evolutionary phenomena. 에볼루션 바카라 무료 is able to study not just the processes and events that take place regularly or over time, but also the relative abundance and distribution of various animal groups in space throughout geological time.
The site is divided into different routes that can be taken to study the subject of evolution. One of these paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also examines myths regarding evolution, and the background of evolutionary thinking.
Each of the other major sections of the Evolution site is similarly created, with resources that support a variety of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia content that include video clips, animations and virtual labs as well as general textual content. The content is laid out in a nested bread crumb style that facilitates navigation and orientation within the vast web site.
The page "Coral Reef Connections" For instance, it gives a brief overview of the coral's relationships, their interaction with other organisms, and then is enlarged to show one clam, which is able to communicate with its neighbors and respond to changes in the conditions of the water that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great introduction to many topics in evolutionary biology. The content also includes a discussion on the significance of natural selectivity and the concept of phylogenetics, an important tool for understanding evolutionary change.
Evolutionary Theory
For biology students evolution is a crucial thread that connects all branches of the field. A vast collection of resources supports teaching about evolution across the life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that offers both the depth and breadth of its educational resources. The site offers a variety of interactive learning modules. It also has an "bread crumb structure" that helps students move away from the cartoon-like style of Understanding Evolution and onto elements on this site that are more closely linked to the worlds of research science. An animation that introduces students to the concept of genetics is linked to a page about John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.
The Evolution Library on this website has a huge multimedia library of materials that deal to evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives set out in the standards for biology. It includes seven short videos specifically designed for use in the classroom, and can be streamed for no cost or purchased on DVD.
Evolutionary biology is an area of study that poses many important questions, including the causes of evolution and the speed at which it happens. This is particularly relevant to human evolution, where it has been difficult to reconcile the idea that the physical characteristics of humans were derived from apes, and the religious beliefs that claim that humans are unique among living things and holds a an exclusive place in the creation. It is soul.
In addition there are a variety of ways that evolution could occur with natural selection being the most popular theory. However, scientists also study other kinds of evolution, such as genetic drift, mutation, and sexual selection, among others.
While many scientific fields of inquiry are in conflict with the literal interpretations of religious texts evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, while others haven't.
