Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution remain. Pop science fiction has led a lot of people to think that biologists don't believe in evolution.
This rich Web site, a companion to the PBS program, provides teachers with materials that promote evolution education while avoiding the types of misconceptions which undermine it. It's laid out in a "bread crumb" format to make navigation and orientation easier.
Definitions
Evolution is a complicated and difficult subject matter to teach well. It is often misunderstood even by non-scientists, and even scientists have been guilty of using definitions that confuse the issue. This is especially applicable to discussions about the nature of the word.
It is crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. It is an accompanying site for the 2001 series, but also a resource of its own. The content is presented in a nested fashion which aids navigation and orientation.
The site defines terms like common ancestor (or common ancestor), gradual process, and adaptation. These terms help frame the nature and significance of evolution to other scientific concepts. The site then offers an overview of how the concept of evolution has been tested and validated. This information can help dispel myths that are created by the creationists.
It is also possible to get a glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable characteristics to become more adaptable to a specific environment. This is a result of natural selection, which occurs when organisms that have better-adapted traits are more likely to survive and reproduce than those with less adapted traits.
Common ancestor (also called common ancestor) is the most recent ancestor that is shared by two or more species. By analyzing the DNA from these species, it is possible to identify the common ancestor.
Deoxyribonucleic acid: A large biological molecule that holds the information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are the cause of new genetic information in cells.
Coevolution is a relation between two species where evolution of one species influence evolutionary changes in the other. 에볼루션 바카라 무료체험 can be seen through the interaction between predator and prey, or parasite and hosts.
Origins
Species (groups of individuals that are able to interbreed) change through natural changes in the traits of their offspring. These changes can be caused by numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of a new species could take thousands of years and the process may be slowed or increased due to environmental conditions, such as climate change or the competition for food or habitat.
The Evolution site tracks the development of various animal and plant groups through time with a focus on the key transitions that occurred in the evolution of each group's history. It also examines the evolutionary history of humans, a topic that is especially important for students to understand.
Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans were discovered. Among them was the famous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was published in 1858, which was a year following the initial edition of The Origin. Origin.
While 에볼루션 바카라 무료 focuses on biology, it also offers a lot of information about geology as well as paleontology. The site offers numerous features that are particularly impressive, including the timeline of the way that climate and geological conditions have changed over time. It also features a map showing the distribution of fossil groups.
The site is a companion for a PBS television series, but it could also be used as an educational resource by teachers and students. The site is well organized and provides clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. There are also links to John Endler's experiments with guppies. They illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has led to an array of animals, plants and insects. Paleobiology is the study of these creatures in their geological environment, has many advantages over modern observational or experimental methods for exploring evolutionary phenomena. In addition to exploring processes and events that take place frequently or over a long period of time, paleobiology can be used to examine the relative abundance of various groups of organisms and their distribution in space over the geological time.
The website is divided into a variety of paths to learning evolution, including "Evolution 101," which takes the user on a linear path through the science of nature and the evidence to support the theory of evolution. The path also examines myths about evolution and also the history of evolutionary thinking.
Each of the main sections on the Evolution website is equally well-designed, with materials that are suited to a variety of levels of curriculum and teaching methods. The site offers a wide array of multimedia and interactive resources that include animations, video clips and virtual labs, in addition to its general textual content. The content is presented in a nested bread crumb style that facilitates navigation and orientation on the web site.
For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interaction with other organisms, then narrows down to a single clam that is able to communicate with its neighbours and respond to changes in water conditions that take place at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, offers a great introduction to a variety of topics in evolutionary biology. The information 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
For biology students evolution is a crucial thread that weaves together all branches of the field. A rich collection supports teaching evolution across all disciplines of life science.
One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that offers both depth and breadth in its educational resources. The site has a variety of interactive learning modules. It also features a nested "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this massive website that are more closely tied to the world of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page highlighting John Endler's experiments in artificial selection with guppies in native ponds of Trinidad.
Another resource that is worth mentioning is the Evolution Library on this site, which has an extensive multimedia library of items that are related to evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives outlined in the standards for biology. It contains seven videos that are designed for use in classrooms. They can be viewed online or purchased as DVDs.
Evolutionary biology remains a field of study that poses many important questions, such as what triggers evolution and how quickly it occurs. This is particularly relevant in the case of human evolution which was a challenge to reconcile religious beliefs that held that humanity has a special place in the creation and a soul, with the idea that innate physical traits evolved from Apes.
There are a myriad of other ways in which evolution can take place and natural selection being the most widely accepted theory. Scientists also study other types like mutation, genetic drift, and sexual selection.
Many fields of inquiry conflict with literal interpretations of the Bible, evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
