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 are saying they do not believe in evolution.
This site, which is a companion to the PBS series - provides teachers with materials that support evolution education and avoids the kinds of misconceptions that undermine it. It's laid out in a "bread crumb" format to aid in navigation and orientation.
Definitions
Evolution is a complicated and challenging subject to teach effectively. People who are not scientists often have a difficult time understanding the subject, and some scientists even use a definition which confuses it. This is particularly relevant when discussing the nature of the words themselves.
It is therefore crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful manner. The site is a companion to the show that premiered in 2001, but it also functions as an independent resource. The content is organized in a manner that makes it easier to navigate and understand.
The site defines terms such as common ancestor and the gradual process. These terms help frame the nature of evolution as well as its relationship to other concepts in science. The site also provides an overview of how the concept of evolution has been tested and verified. This information can help dispel myths that are created by the creationists.
It is also possible to find the glossary of terms used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to be better suited to an environment. This is the result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adaptable characteristics to survive and reproduce.
Common ancestor: The most recent common ancestor of two or more species. The common ancestor can be identified through analyzing the DNA of the species.
Deoxyribonucleic Acid: A huge biological molecular containing the necessary information for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are responsible for the creation of new genetic information within cells.
Coevolution is a relationship between two species where evolution of one species influence evolutionary changes of the other. Coevolution can be observed in the interactions between predator and prey, or parasites and hosts.
Origins
Species (groups that can crossbreed) develop by a series of natural variations in their offspring's traits. Changes can be caused by numerous factors, like natural selection, gene drift and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food or habitat, can slow or accelerate the process.
The Evolution site traces through time the evolution of different species of plants and animals and focuses on major changes in each group's past. It also focuses on the human evolutionary roots and humans, a subject that is particularly important for students to understand.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. Among them was the famous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, one year after the first edition of The Origin. Origin.
While the site focuses on biology, it also contains a wealth of information on geology and paleontology. The website has several aspects that are quite impressive, including the timeline of the way that climate and geological conditions have changed over time. It also includes a map showing the distribution of fossil groups.
The site is a companion for the PBS TV series but it can also be used as a source for teachers and students. The site is extremely well-organized and offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum Web site. These hyperlinks facilitate the move 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 using Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures within their geological context offers many advantages over modern observational or research methods for studying evolutionary processes. Paleobiology focuses on not only the process and events that happen regularly or over time, but also the distribution and frequency of various animal groups in space throughout geological time.
The site is divided into several options to study the subject of evolution. One of the paths, "Evolution 101," walks the reader through the evolution of nature and the evidence of evolution. The path also explores common misconceptions about evolution as well as the history of evolutionary thought.
Each of the other main sections of the Evolution site is similarly created, with resources that can be used to support a range of different pedagogical levels and curriculum levels. In addition to the standard textual content, the site offers an array of multimedia and interactive resources, such as video clips, animations, and virtual labs. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the large web site.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and interactions with other organisms and then is enlarged to show one clam, which is able communicate with its neighbors and respond to changes in conditions of the water at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, gives a good introduction to a variety of topics in evolutionary biology. The content also includes a discussion on the significance of natural selectivity and the concept phylogenetics analysis, an important tool to understand evolutionary change.
Evolutionary Theory
Evolution is an underlying thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach evolution across all life science disciplines.
One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that provides depth and broadness in terms of educational resources. The site has a variety of interactive learning modules. It also features a nested "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely tied to the field of research science. An animation that introduces students to the concept of genetics links to a page highlighting John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.
Another useful resource is the Evolution Library on this web website, which includes an extensive library of multimedia resources that are related to evolution. The content is organized into curricula-based paths that correspond to the learning objectives outlined in the standards for biology. It includes seven short videos designed specifically for use in classrooms, and can be streamed for free or purchased on DVD.
에볼루션 슬롯게임 is still a field of study that poses many important questions to answer, such as the causes of evolution and how quickly it occurs. This is particularly relevant for the evolution of humans which was a challenge to reconcile religious beliefs that held that humanity has a unique place in creation and a soul, with the notion that human beings have innate physical traits originated from apes.
In addition there are a myriad of ways that evolution could occur and natural selection is the most widely accepted theory. However, scientists also study other types of evolution such as genetic drift, mutation, and sexual selection, among others.
While many fields of scientific inquiry are in conflict with literal interpretations of the Bible evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, but others haven't.
