Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, there are still a lot of misconceptions regarding evolution. People who have been exposed to the nonsense of pop science often believe that biologists are saying they don't believe in evolution.
This rich Web site, a companion to the PBS program, provides teachers with materials that support the evolution of education, while avoiding the kinds of misconceptions that can make it difficult to understand. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
It is difficult to teach evolution well. Non-scientists often misunderstand the subject and some scientists use a definition which confuses it. This is especially true when it comes to discussions on the definition of the word itself.
As such, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. It is an accompaniment to the 2001 series, and also a resource of its own. The information is presented in an organized way that makes it easy to navigate and understand.
The site defines terms such as common ancestor and the gradual process. These terms help to define the nature of evolution as well as its relation to other concepts in science. The site also provides an overview of how the concept of evolution has been researched and confirmed. This information will help to dispel the myths that are created by the creationists.
You can also access a glossary that contains terms used in evolutionary biology. These terms include:
Adaptation: The tendency of heritable characteristics to become more suitable to a particular setting. This is the result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adaptable traits to reproduce and survive.
Common ancestor (also called common ancestor) is the most recent ancestor that is shared by two or more species. The common ancestor can be identified by analyzing the DNA of the species.
Deoxyribonucleic acid: A massive biological molecule that contains information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, also known as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.
Coevolution is a relationship between two species in which the evolutionary changes of one species are influenced by evolutionary changes of the other. Examples of coevolution are the interactions between predator and prey, or parasite and host.
Origins
Species (groups of individuals that can interbreed) change through an array of natural changes in the traits of their offspring. The changes can be triggered by a variety of causes that include natural selection, genetic drift and mixing of genes. The evolution of a new species could take thousands of years and the process may be slowed down or speeded up due to environmental conditions, such as climate change or competition for food or habitat.
The Evolution site traces through time the emergence of various animal and plant groups and focuses on major changes in each group's history. It also explores the human evolutionary roots which is particularly important for students to comprehend.
Darwin's Origin was written in 1859, when only a few antediluvian fossils of human beings had been discovered. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year before the first edition of the Origin appeared, it is very unlikely that Darwin had heard or seen of it.
While the site is focused on biology, it also contains a wealth of information about geology and paleontology. The Web site has several aspects that are quite impressive,

Fsquan8.Cn) such as a timeline of the way that climate and geological conditions have changed over time. It also features an interactive map that shows the location of fossil groups.
The site is a companion for the PBS television series, but it can be used as a source for teachers and students. The site is very well-organized and has clear links between the introductory 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 make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are links to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has led to a wide variety of plants, animals,
에볼루션 카지노 and insects. Paleobiology is the study of these creatures in their natural environment offers many advantages over modern observational or research methods for studying evolutionary phenomena. In addition to studying the processes and events that happen regularly or over a lengthy period of time, paleobiology can be used to examine the relative abundance of different kinds of organisms as well as their distribution across geological time.
The site is divided into a variety of ways to learn about evolution which include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence supporting the theory of evolution. The path also explores misconceptions regarding evolution,
에볼루션 슬롯게임 and also the history of evolutionary thinking.
Each of the other main sections of the Evolution site is similarly created,
에볼루션코리아 with resources that can support a variety of educational levels and pedagogical styles. The site includes a variety of interactive and multimedia content that include videos, animations, and virtual laboratories as well as general textual content. The content is organized in a nested, bread crumb fashion that aids navigation and orientation within the large Web site.
For example, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms, then zooms in on a single clam that is able to communicate with its neighbours and respond to changes in the water conditions at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to the broad range of topics in evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool for 에볼루션 무료 바카라 (

Evolutionary Theory
Evolution is an underlying thread that is found throughout all branches of biology. A wide range of resources helps teachers teach about evolution across the life sciences.
One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that provides the depth and the breadth in terms of its educational resources. The site offers a variety of interactive learning modules. It also has a "bread crumb structure" that allows students to move away from the cartoon-like style that is used in Understanding Evolution and onto elements on this large website more closely connected to the worlds of research science. An animation that introduces the concept of genetics links to a page that highlights John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.
