Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution persist. People who have absorbed popular science myths often assume that biologists don't believe in evolution.
This rich Web site - companion to the PBS series - provides teachers with materials which support evolution education and help avoid the kinds of myths that hinder it. It's laid out in a "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complex and difficult subject to teach well. Many non-scientists are unable to grasp the concept and some scientists employ a definition that confuses it. This is especially applicable to discussions on the definition of the word itself.
It is essential to define terms used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful manner. The site is a companion site to the series that first aired in 2001, but also functions as an independent resource. The information is presented in an organized manner that makes it easier to navigate and comprehend.
The site defines terms such as common ancestor, gradual process and adaptation. These terms help frame the nature and relationship of evolution to other concepts in science. The site also provides an overview of how the concept of evolution has been vetted and verified. This information will help to dispel the myths created by creationists.
You can also access a glossary that includes terms that are used in evolutionary biology. These terms include:
Adaptation is the process of changing heritable traits to be more suited to the environment. This is the result of natural selection. Organisms with better-adapted traits are more likely than those with less adaptable traits to reproduce and survive.
Common ancestor (also called common ancestor): The most recent ancestral ancestor shared by two or more species. By analyzing the DNA from these species it is possible to determine the common ancestor.
Deoxyribonucleic acid: A large biological molecule that contains the information necessary 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 in cells.
Coevolution: A relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution is evident in the interactions between predator and prey, or parasite and hosts.
Origins
Species (groups of individuals that can interbreed) change through natural changes in the characteristics of their offspring. These changes are caused by a variety of factors such as natural selection, genetic drift, and gene pool mixing. The evolution of a new species could take thousands of years, and the process may be slowed or increased by environmental factors like climate change or the competition for food or

The Evolution site traces the emergence of various groups of animals and plants over time,
바카라 에볼루션 focusing on the major transitions that occurred in each group's history. It also focuses on human evolution, which is a topic that is of particular interest to students.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The famous skullcap, with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, 에볼루션 사이트 (

While the site focuses on biology, it offers a lot of information about geology as well as paleontology. The most impressive features on the site are a set of timelines that illustrate how climatic and geological conditions changed over time, as well as a map of the distribution of a few fossil groups that are featured on the site.
While the site is a companion to a PBS television series but it also stands on its own as a great resource for 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 sophisticated components of the museum's Web site. These links make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are also 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 within their geological context and
에볼루션 바카라사이트 has a number of advantages over the current observational and experimental methods of examining evolutionary phenomena. Paleobiology can examine not only the process and events that occur frequently or
바카라 에볼루션 over time, but also the distribution and frequency of different species of animals across geological time.
The website is divided into different paths that can be chosen to study the subject of evolution. One of these paths, "Evolution 101," walks the reader through the evolution of nature and the evidence of evolution. The course also focuses on common misconceptions about evolution and the evolution theory's history.
Each of the main sections on the Evolution website is equally well-developed, with materials that are suited to a variety of levels of curriculum and teaching methods. In addition to general textual content, the site offers an array of multimedia and interactive resources, such as videos, animations, and virtual labs. The content is presented in a nested bread crumb fashion that aids navigation and orientation on the Web site.
The page "Coral Reef Connections", for example, provides a comprehensive overview of the relationships between corals, their interaction with other organisms and zooms in on one clam that is able communicate with its neighbours and respond to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to the broad spectrum of topics in evolutionary biology. The material includes an explanation of the significance of natural selectivity and the concept phylogenetics analysis, an important tool for understanding evolutionary changes.
Evolutionary Theory
For biology students the concept of evolution is a major thread that binds all branches of the field. A vast collection of resources can help teachers teach about evolution across the life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that provides the depth and breadth of its educational resources. The site features a wealth of interactive learning modules. It also features an "bread crumb structure" that allows students to move away from the cartoon style of Understanding Evolution and onto elements of this vast website that are closely linked to the fields of research science. Animation that introduces the concept of genetics, which links to a page that highlights John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.
The Evolution Library on this website is a vast multimedia library of materials that deal to evolution. The content is organized into courses that are based on curriculum and follow the learning objectives set out in the biology standards.
