Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, there are still a lot of misconceptions about evolution. People who have taken in popular science myths often assume that biologists are saying they do not believe in evolution.
This rich Web site, a companion to the PBS program, provides teachers with materials that promote evolution education, while avoiding the kinds of misconceptions which hinder it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complex and difficult subject to teach well. It is often misunderstood by non-scientists, and even scientists have been guilty of using an interpretation that is confusing the issue. This is especially relevant when it comes to the meaning of the words themselves.
It is essential to define terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. The site serves as an accompanying site for the 2001 series, and it is also a resource on its own. The material is presented in a nested fashion that aids navigation and orientation.
The site defines terms like common ancestor and gradual process. These terms help frame the nature of evolution and its relationship to other concepts in science. The website provides a summary of the manner that evolution has been examined. This information can be used to dispel misconceptions that have been created by the creationists.
You can also consult a glossary that includes terms that are used in evolutionary biology. 에볼루션 슬롯게임 include:
The process of adaptation is the tendency of heritable traits to be more suited to the environment. This is due to natural selection, which occurs when organisms that have more adaptable characteristics are more likely to survive and reproduce than those with less adaptable characteristics.
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 studying the DNA of the species.
Deoxyribonucleic acid: A huge biological molecule that contains information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
Coevolution is a relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or host and parasite.
Origins
Species (groups of individuals who can interbreed) evolve through natural changes in the characteristics of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift and mixing of the gene pool. The development of a new species could take thousands of years and the process may be slowed down or accelerated due to environmental conditions, such as climate change or competition for food or habitat.
The Evolution site tracks through time the evolution of different groups of animals and plants, focusing on major transitions in each group's history. It also explores human evolution and is a subject that is particularly important for students.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The skullcap that is famous, along with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was first published in 1858, a year after the first edition of The Origin. Origin.
While the site is focused on biology, it contains a wealth of information about geology and paleontology. The Web site has a number of features that are especially impressive, including a timeline of the way that climate and geological conditions have changed over the course of time. It also features an interactive map that shows the location of fossil groups.
While the site is a companion piece to the PBS television show, it also stands on its own as an excellent source for teachers and students. The site is very well-organized and has clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum Web site. These hyperlinks make it easy 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 that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a variety of plants, animals, and insects. Paleobiology, the study of these creatures within their geological context, has many advantages over modern observational or experimental methods for studying evolutionary processes. Paleobiology can examine not just the processes and events that occur frequently or over time, but also the distribution and frequency of different species of animals in space throughout geological time.
The site is divided into several optional pathways to understanding evolution, including "Evolution 101," which takes the user on a linear path through the science of nature and the evidence that supports the theory of evolution. The path also explores common misconceptions about evolution and the evolution of thought.
Each of the main sections of the Evolution website is equally well-designed, with materials that can be used to support a variety of educational levels and teaching styles. In addition to the standard textual content, the site also has a wide range of multimedia and interactive resources like video clips, animations, and virtual labs. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the vast web site.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of the coral's relationships and interactions with other organisms, and then is enlarged to show one clam, which is able to communicate with its neighbors 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 a broad spectrum of topics in evolutionary biology. The material includes a discussion on the role of natural selectivity and the concept of phylogenetics analysis which is a crucial method for understanding the evolution of changes.
Evolutionary Theory
For biology students evolution is a crucial thread that weaves together all the branches of the field. A vast collection of books helps in teaching evolution across all disciplines of life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that provides depth and a variety of educational resources. The site features a wealth of interactive learning modules. It also has an embedded "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site closer to the world of research science. For example an animation that explains the concept of genetic inheritance links to a page highlighting John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.
The Evolution Library on this website contains a large multimedia library of materials that deal with evolution. The contents are organized into curriculum-based paths that parallel the learning objectives set out in the standards for biology. It includes seven short videos specifically intended for use in the classroom. 에볼루션 무료 바카라 are available to stream or purchase as DVDs.
A number of important questions remain at the core of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is particularly true for the evolution of humans where it was a challenge to reconcile religious beliefs that held that humanity has a special position in the universe and a soul with the idea that innate physical traits evolved from apes.
In addition there are a variety of ways in which evolution could be triggered and natural selection is the most widely accepted theory. Scientists also study other kinds such as mutation, genetic drift and sexual selection.
While many fields of scientific study conflict with literal interpretations found in religious texts, evolution biology has been a source of intense debate and resistance from religious fundamentalists. Certain religions have embraced their beliefs to evolution but others haven't.
