15 Shocking Facts About Evolution Site That You Never Knew
Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution persist. People who have taken in pop science nonsense often assume that biologists do not believe in evolution.
This site, which is a companion to the PBS program, provides teachers with materials which support evolution education while avoiding the types of misconceptions that hinder it. It's organized in a "bread crumb" format to make navigation and orientation easier.
Definitions
It's difficult to effectively teach evolution. It is often misunderstood by non-scientists and even scientists have been guilty of using definitions that confuse the issue. This is especially true when it comes to discussions on the nature of the word.
It is essential to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. It is an accompanying site for the 2001 series, and also a resource of its own. The content is presented in a way which aids navigation and orientation.
The site defines terms like common ancestor and the gradual process. These terms help to define the nature of evolution and its relationship to evolution with other scientific concepts. The site provides an overview of the ways in which evolution has been examined. This information can help dispel myths created by creationists.
It is also possible to access a glossary of terms used in evolutionary biology. These terms include:
Adaptation is the tendency of hereditary traits to become better suited to an environment. This is the result of natural selection. It occurs when organisms with more adaptable traits are more likely survive and reproduce than those with less adaptable characteristics.
Common ancestor: The most recent common ancestor of two or more distinct species. By analyzing the DNA from these species, it is possible to identify the common ancestor.
Deoxyribonucleic acid: A huge biological molecule that holds the information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells.
Coevolution is a relationship between two species in which the evolution of one species influence evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or parasite and host.
Origins
Species (groups that can interbreed) develop through a series of natural changes in the traits of their offspring. These changes are caused by a variety of factors that include natural selection, genetic drift, and mixing of gene pools. The development of new species can take thousands of years. Environmental conditions, like climate changes or competition for food resources and habitat can slow or speed up the process.
The Evolution site follows the emergence of various animal and plant groups with a focus on major changes in each group's history. It also examines the evolutionary history of humans and humans, a subject that is crucial for students to comprehend.
When Darwin wrote the Origin of Species, 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 known as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was first published in 1858, one year after the publication of the first edition of The Origin.
While the site is focused on biology, it contains a wealth of information about geology as well as paleontology. The Web site has several features that are particularly impressive, such as a timeline of the way that climate and geological conditions have changed over the course of time. It also features maps that show the locations of fossil groups.
The site is a companion to the PBS television series, but it could also be used as a source for teachers and students. The site is well organized and provides clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. These hyperlinks help users move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has produced a diversity of animals, 에볼루션 바카라 체험 에볼루션 바카라 무료 [bramsen-Fitzgerald.technetbloggers.de] plants and insects. Paleobiology is the study of these creatures within their natural environment is a superior method of study over the current observational or experimental methods for 에볼루션바카라사이트 studying evolutionary processes. Paleobiology focuses on not only processes and events that occur regularly or over time but also the relative abundance and distribution of different species of animals in space throughout the geological time.
The site is divided into several options to learn about evolution. One of these paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also reveals the most common misconceptions about evolution, as well as the evolution of thought.
Each of the main sections of the Evolution website is equally well-developed, and includes materials that can be used to support a variety of levels of curriculum and teaching methods. In addition to general textual content, the site offers an extensive selection of interactive and multimedia resources including videos, animations and virtual labs. The content is presented in a nested bread crumb style that facilitates navigation and orientation within the vast web site.
For example, 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 react to changes in water conditions at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to the broad variety of topics in evolutionary biology. The content also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis which is a key tool for understanding the evolution of changes.
Evolutionary Theory
For biology students, evolution is a key thread that connects all the branches of the field. A rich collection of resources supports teaching about evolution across all life sciences.
One resource, the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that provides depth and broadness in terms of educational resources. The site features a wealth of interactive learning modules. It also features an embedded "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this massive website that are more closely linked to the world of research science. Animation that introduces the concept of genetics links to a page about John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad.
The Evolution Library on this website is a vast multimedia library of materials that deal to evolution. The content is organized into curriculum-based pathways that correspond to the learning goals set forth in the standards for biology. It includes seven short videos that are designed for classroom use. They are available to stream or purchase as DVDs.
Evolutionary biology is a field of study that has many important questions to answer, such as the causes of evolution and how fast it happens. This is particularly true in the case of human evolution, where it was difficult to reconcile religious beliefs that held that humanity has a unique position in the universe and a soul with the notion that our physical traits originated from Apes.
In addition there are a myriad of ways that evolution can occur, with natural selection being the most widely accepted theory. However, 에볼루션 바카라사이트 (http://wzgroupup.hkhz76.Badudns.cc/Home.php?mod=space&uid=2310466) scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among others.
While many scientific fields of study are in conflict with literal interpretations in religious texts, evolution biology has been the subject of intense debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, but others haven't.
