Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution persist. People who have taken in popular science myths often assume that biologists are saying they do not believe in evolution.
This rich Web site - companion to the PBS series It provides teachers with materials which support evolution education and help avoid the kinds of misconceptions that undermine it. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
Evolution is a complicated and challenging subject to teach effectively. It is often misunderstood by non-scientists and even some scientists have been guilty of using definitions that confuse the issue. This is especially relevant when discussing the meaning of the words themselves.
It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The website is a companion to the show that premiered in 2001, but is also an independent resource. The content is presented in a nested fashion that assists in navigation and orientation.
The site defines terms like common ancestor and the gradual process. These terms help to define the nature and relationship of evolution to other scientific concepts. The site provides an overview of the manner in which evolution has been tested. This information can be used to dispel myths that have been propagated by the creationists.
You can also consult a glossary that includes terms that are 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 occurs when organisms that are more adaptable characteristics are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor (also known as common ancestor) The most recent ancestral ancestor shared by two or more species. By studying the DNA of these species it is possible to determine the common ancestor.
Deoxyribonucleic acid: A massive biological molecule that contains the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains called chromosomes. Mutations are responsible for the creation of new genetic information within cells.
Coevolution is a relation between two species, where the evolutionary changes of one species influence evolutionary changes of the other. Coevolution can be observed in the interaction of predator and prey, or parasites and hosts.
Origins
Species (groups which can interbreed), evolve through a series of natural changes in the traits of their offspring. The changes can be caused by a variety, including natural selection, genetic drift, and mixing of genes. The evolution of a new species could take thousands of years and the process can be slowed down or accelerated by environmental factors like climate change or the competition for food or habitat.
The Evolution site follows the evolution of different groups of animals and plants with a focus on major changes within each group's past. It also explores the human evolutionary roots which is crucial for students to understand.
When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, a year following the initial edition of The Origin.
The site is mostly one of biology however, it also has many details on geology and paleontology. The Web site has numerous features that are particularly impressive, including a timeline of how geological and climate conditions have changed over time. It also has an interactive map that shows the location of fossil groups.
The site is a companion for a PBS TV series but it can also be used as a source for 에볼루션 카지노 teachers and students. The site is well-organized and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features of the museum's website. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular, there are links to John Endler's experiments using Guppies, 에볼루션 바카라 무료 바카라에볼루션 사이트 (please click the following internet site) which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life 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 the modern observational and research methods of examining evolutionary processes. In addition to exploring the processes and events that happen frequently or over a long period of time, paleobiology allows to examine the diversity of species of organisms and their distribution in space over the course of geological time.
The website is divided into a variety of pathways to understanding evolution, including "Evolution 101," which takes the viewer on a line through the scientific process and the evidence that supports the theory of evolution. The path also explores common misconceptions about evolution and the evolution of thought.
Each of the other major sections of the Evolution site is equally well developed, with materials that can support a variety of different pedagogical levels and curriculum levels. In addition to general textual content, the site features an array of multimedia and interactive resources, such as videos, animations, and virtual laboratories. The content is organized in a nested, bread crumb fashion that aids navigation and orientation within the large web site.
For instance, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interaction with other organisms, then narrows down to a single clam that is able to communicate with its neighbors and react to changes in water conditions at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to the broad variety of topics in evolutionary biology. The content also includes a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a key tool for understanding the evolution of changes.
Evolutionary Theory
Evolution is a common thread that runs through all branches of biology. A vast collection of resources helps teachers teach 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 provides depth and breadth in its educational resources. The site features a wide range of interactive learning modules. It also features an encased "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the world of research science. For instance, an animation introducing the idea of genetic inheritance connects to a page that highlights John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.
The Evolution Library on this website is a vast multimedia library of materials that deal with evolution. The content is organized into curriculum-based pathways that correspond to the learning goals set forth in the standards for biology. It contains seven videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.
A variety of crucial questions remain in the midst of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is particularly relevant for humans' evolution which was a challenge to reconcile religious beliefs that humans have a distinct place in the creation and a soul, with the notion that human beings have innate physical traits were derived from the apes.
Additionally, there are a number of ways in which evolution could be triggered and natural selection is the most popular theory. Scientists also study other types like mutation, genetic drift and sexual selection.
While many scientific fields of study conflict with the literal interpretations of religious texts, the concept of evolution biology has been the subject of intense debate and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, while others haven't.
