Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions persist about the evolution. People who have taken in popular science myths often assume that biologists do not believe in evolution.
This rich website - companion to the PBS series It provides teachers with materials that support evolution education and avoids the kinds of misinformation that can make it difficult to understand. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complicated and challenging subject to teach effectively. It is often misunderstood by non-scientists, and even scientists have been guilty of using a definition that confuses the issue. This is especially true when it comes to debates about the nature of the word.
Therefore, it is important to define terms used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful way. The site is both an accompaniment to the 2001 series, and also a resource of its own. The material is presented in a way that assists in 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 provides an overview of the way that evolution has been tested. This information will help to dispel the myths that are created by the creationists.
You can also access a glossary which contains terms that are used in evolutionary biology. These terms include:
Adaptation: The tendency of hereditary traits to become more suited to a particular environment. This is the result of natural selection. It occurs when organisms that are better-adapted characteristics are more likely to survive and reproduce than those with less adapted traits.
Common ancestor: The most recent common ancestor of two or more species. By analyzing DNA from these species, it is possible to identify the common ancestor.
Deoxyribonucleic acid: A huge biological molecule that holds the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are the basis for new genetic information within cells.
Coevolution is the relationship between two species in which the evolutionary changes of one species are influenced evolutionary changes in the other. Coevolution can be observed through the interaction between predator and prey, or parasite and hosts.
에볼루션 슬롯게임 (groups of individuals that can interbreed) develop through natural changes in the characteristics of their offspring. The causes of these changes are various factors, including natural selection, gene drift, and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, such as climate change or competition for food and habitat can impede or accelerate the process.
The Evolution site follows the evolution of different animal and plant groups with a focus on major changes within each group's past. It also focuses on human evolution, which is a topic that is particularly important for students.
When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. One of them was the infamous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was published in 1858, one year after the publication of the first edition of The Origin.
While the site is focused on biology, it also includes a good deal of information about geology and paleontology. The website has a number of 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 has an interactive map that shows the location of fossil groups.
The site is a companion to a PBS TV series but it can be used as a resource by teachers and students. The site is extremely well-organized and offers clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated components of the museum's Web site. These hyperlinks make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler’s experiments with guppies. They 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 geological context and has many advantages over modern observational and experimental methods of examining evolutionary phenomena. Paleobiology can examine not only the process and events that occur regularly or over time, but also the distribution and frequency of different groups of animals across geological time.
The Web site is divided into a variety of ways to learn about evolution that include "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence to support the theory of evolution. The course also focuses on misconceptions regarding evolution, and the background of evolutionary thinking.
Each of the other main sections of the Evolution site is equally constructed, with materials that can be used to support a range of educational levels and pedagogical styles. The site includes a variety of interactive and multimedia content, including videos, animations, and virtual labs as well as general textual content. The content is presented in a nested bread crumb-like fashion that helps with navigation and orientation within the large Web site.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms and zooms in to one clam that can communicate with its neighbours and respond to changes in the conditions of the water at the reef level. 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 an explanation of the role of natural selection as well as the concept of phylogenetic analysis, which is an important tool in understanding evolutionary changes.

For biology students the concept of evolution is a major thread that binds all the branches of the field. A rich collection supports teaching evolution across all life science disciplines.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that offers both the depth and the breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also has a "bread crumb structure" that allows students to move away from the cartoon-like style of Understanding Evolution and onto elements of this vast website that are closely related to the worlds of research science. An animation that introduces students to the concept of genetics links to a page that highlights John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.
Another useful resource is the Evolution Library on this web site, which contains an extensive collection of multimedia assets related to evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives set out in the standards for biology. It contains seven videos specifically designed for classroom use, which can be streamed for free or purchased on DVD.
Evolutionary biology is still an area of study that poses many important questions to answer, such as what triggers evolution and how fast it takes place. This is particularly relevant for the evolution of humans where it was a challenge to reconcile religious beliefs that held that humanity has a unique place in creation and a soul with the notion that our physical traits evolved from apes.
There are also a number of other ways in which evolution could occur and natural selection being the most popular theory. However scientists also study other types of evolution such as mutation, genetic drift, and sexual selection, among others.
While many fields of scientific inquiry have a conflict with the literal interpretations of the Bible Evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, others have not.
