Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions persist about evolution. 에볼루션 has led many people to believe that biologists aren't believers in evolution.
This rich Web site, which is a companion to the PBS program that provides teachers with resources which support evolution education, while avoiding the kinds of misconceptions that can make it difficult to understand. It's laid out in a "bread crumb" format to aid in navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach well. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition that confuses it. 에볼루션 카지노 사이트 is especially relevant to debates about the nature of the word.
It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. It is an accompaniment to the 2001 series, but also a resource on its own. The information is organized in a manner that makes it simpler to navigate and understand.
The site defines terms like common ancestor, gradual process and so on. These terms help frame the nature of evolution as well as its relation to other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and validated. This information can be used to dispel misconceptions that have been propagated by creationists.
It is also possible to access the glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency of hereditary traits to become more adaptable to a specific environment. This is the result of natural selection, which happens when organisms that are more adaptable traits are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor (also known as common ancestor) The most recent ancestor shared by two or more species. By studying the DNA of these species, it is possible to identify the common ancestor.
Deoxyribonucleic Acid: A huge biological molecular that holds the information needed for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the basis for 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 include the interaction between predator and prey, or parasite and host.
Origins
Species (groups of individuals that are able to interbreed) evolve through natural changes in the characteristics of their offspring. The changes can be caused by a variety such as natural selection, genetic drift, and mixing of gene pools. The evolution of new species could take thousands of years. Environmental circumstances, such as climate change or competition for food and habitat, can slow or accelerate the process.
The Evolution site traces through time the evolution of different groups of animals and plants, focusing on major transitions within each group's past. It also focuses on human evolution as a subject that is particularly important to students.
Darwin's Origin was published in 1859, when only a handful of antediluvian fossils of humans were discovered. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was published in 1858, one year following the initial edition of The Origin. Origin.
The site is primarily a biology site however, it also has lots of information about paleontology and geology. One of the most appealing features of the Web site are a set of timelines which show the way in which climatic and geological conditions changed over time, as well as an outline of the distribution of some of the fossil groups featured on the site.
While the site is a companion to a PBS television show, it also stands on its own as a valuable resource for teachers and students. 에볼루션코리아 is well-organized and has clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These hyperlinks facilitate the move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are hyperlinks to John Endler's research with guppies that illustrate 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 geological context and has many advantages over modern observational and experimental methods in its exploration of evolutionary processes. Paleobiology focuses on not just the processes and events that happen regularly or over time, but also the distribution and frequency of different groups of animals in space throughout the geological time.
The website is divided into different options to learn about evolution. One of the paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also examines myths about evolution, and the background of evolutionary thinking.
Each of the main sections of the Evolution website is equally well-developed, with materials that support a variety educational levels and teaching styles. The site has a range of interactive and multimedia content, including videos, animations, and virtual labs, in addition to its general textual content. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation on the Web site.
The page "Coral Reef Connections" For instance, it provides a comprehensive overview of the relationships between corals and interactions with other organisms and then is enlarged to show one clam, which can communicate with its neighbors and respond to changes in conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a wide spectrum of topics in evolutionary biology. The material includes an overview of the importance of natural selection and the concept phylogenetics analysis, an important method for understanding the evolution of change.
Evolutionary Theory
Evolution is a common thread that connects all branches of biology. A rich collection of resources can help teachers teach about evolution across the life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both depth and a variety of educational resources. The site offers a range of interactive learning modules. It also features 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 related to the realms of research science. An animation that introduces students to the concept of genetics is linked to a page highlighting John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.
Another helpful resource is the Evolution Library on this site, which contains an extensive library of multimedia assets related to evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning goals set forth in the biology standards. It contains seven videos specifically designed for classroom use, which can be streamed for no cost or purchased on DVD.
A variety of crucial questions remain at the core of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is especially applicable to human evolution where it's been difficult to reconcile that the physical traits of humans evolved from apes with religious beliefs that hold that humanity is unique among living things and has a special place in creation. It is a soul.
Additionally, there are a number of ways in which evolution could be triggered and natural selection is the most widely accepted theory. However, scientists also study other kinds of evolution, such as mutation, genetic drift, and sexual selection, among other things.
While many fields of scientific inquiry have a conflict with literal interpretations of religious texts evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
