Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution remain. People who have been exposed to pop science nonsense often assume that biologists claim they do not believe in evolution.
This site, which is a complement to the PBS program, provides teachers with materials which support evolution education, while avoiding the kinds of misconceptions that can hinder it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
It is difficult to properly teach evolution. It is often misunderstood by non-scientists, and even some scientists have been guilty of using definitions that confuse the issue. This is especially true when discussing the nature of the words themselves.
It is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site is both a companion for the 2001 series, and also a resource of its own. The material is presented in a nested manner which aids navigation and orientation.
The site defines terms like common ancestor, gradual process and so on. These terms help frame the nature of evolution as well as its relationship to other scientific concepts. The site provides an overview of the manner in which evolution has been tested. This information can help dispel the myths created by creationists.
You can also access a glossary that includes terms used in evolutionary biology. These terms include:
Adaptation is the process of changing heritable traits to be better suited to an environment. This is the result of natural selection. It occurs when organisms that have better-adapted traits are more likely to survive and reproduce than those with less adaptable traits.
Common ancestor (also called common ancestor) is the most recent ancestor shared by two or more species. By analyzing DNA from these species it is possible to identify the common ancestor.
Deoxyribonucleic acid: A large biological molecule that contains information necessary for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, also known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.
에볼루션 슬롯게임 is a relation between two species, where the evolution of one species are influenced by evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey or the parasite and the host.
Origins
Species (groups that can interbreed) change by a series of natural variations in their offspring's traits. The changes can be caused by a variety such as natural selection, genetic drift and gene pool mixing. The development of a new species can take thousands of years, and the process could be slowed down or speeded up by environmental factors like climate change or competition for food or habitat.
The Evolution site traces the emergence of a variety of species of plants and animals over time, focusing on the major transitions that occurred in the history of each group. It also focuses on human evolution and is a subject that is particularly important to students.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The famous skullcap, with the bones that accompanied it, was 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 was aware of the skullcap, which was first published in 1858, a year after the first edition of The Origin. Origin.
The site is mostly an online biology resource however it also includes lots of information about paleontology and geology. One of the most appealing features of the website are a timeline of events which show how geological and climatic conditions have changed over time as well as an interactive map of the distribution of a few fossil groups listed on the site.
The site is a companion to a PBS television series, but it could be used as a source for teachers and students. The site is well-organized, and provides clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized features on the museum's website. These links facilitate the transition from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world 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 on Earth has resulted in a variety of animals, plants, and insects. Paleobiology is the study of these creatures in their natural environment and has a number of advantages over the modern observational and research methods in its exploration of evolutionary phenomena. Paleobiology is able to study not only the process and events that occur regularly or over time but also the relative abundance and distribution of different species of animals across the geological time.
The site is divided into various ways to learn about evolution, including "Evolution 101," which takes the viewer on a liner path through the scientific process and the evidence to support the theory of evolution. The path also explores misconceptions about evolution, as well as the history of evolutionary thinking.
Each of the other sections of the Evolution site is equally constructed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. The site includes a variety of interactive and multimedia content, including animations, video clips and virtual laboratories in addition to general textual content. The breadcrumb-like structure of the content assists with navigation and orientation on the large Web site.
For instance, the page "Coral Reef Connections" provides an overview of coral relationships and their interactions with other organisms, then zooms in on a single clam that can communicate with its neighbors and respond to changes in water conditions that take place at the level of the reef. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a broad spectrum 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 change.
Evolutionary Theory
Evolution is an underlying thread that is found throughout all branches of biology. 에볼루션카지노사이트 teaching evolution across the disciplines of life sciences.
One resource, the companion to PBS's television show Understanding Evolution is an excellent example of a Web site that provides the depth and the broadness in terms of educational resources. The site features a wealth of interactive learning modules. It also features an "bread crumb structure" that assists students in moving away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely connected to the worlds of research science. For instance, an animation introducing the idea of genetic inheritance connects to a page that focuses on John Endler's artificial selection experiments with guppies in native ponds of Trinidad.
Another resource that is worth mentioning is the Evolution Library on this site, which contains an extensive multimedia library of items connected to evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives outlined in biology standards. It contains seven short videos specifically intended for use in the classroom. These can be viewed online or purchased as DVDs.
Evolutionary biology is a field of study that has many important questions, including what causes evolution and how fast it occurs. This is particularly true for humans' evolution where it was a challenge to reconcile religious beliefs that held that humanity has a special place in creation and a soul, with the notion that human beings have innate physical traits were derived from apes.
There are a myriad of other ways evolution could occur, with natural selection as the most well-known theory. However scientists also study different types of evolution such as genetic drift, mutation, and sexual selection, among others.
While many fields of scientific study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been the subject of intense debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, others have not.
