Evolution Site - Teaching About Evolution
Despite the best efforts by biology teachers, there are still misconceptions about evolution. People who have taken in popular science myths often assume that biologists claim they do not believe in evolution.
This site, which is a 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 organized in a "bread crumb" format to aid in navigation and orientation.
Definitions
It's difficult to properly teach evolution. It is often misunderstood by non-scientists and even some scientists have been guilty of using a definition that confuses the issue. This is especially relevant when discussing the nature of the words themselves.
Therefore, it is important to define terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient way. The site is both a companion for the 2001 series, and also a resource on its own. The information is presented in an organized manner that makes it easier to navigate and understand.
The site defines terms like common ancestor and gradual process. These terms help frame the nature and relationship of evolution to other scientific concepts. The site also provides an overview of how the concept of evolution has been researched and confirmed. This information can help dispel the myths created by creationists.
It is also possible to get the glossary of terms used in evolutionary biology. These terms include:
Adaptation is the tendency of heritable traits to become more suitable to their environment. This is the result of natural selection, which happens when organisms that have more adaptable traits are more likely to survive and reproduce than those with less adaptable traits.
Common ancestor: The latest common ancestor of two or more distinct species. mouse click the up coming post can be identified by analyzing the DNA of those species.
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 known as chromosomes. click the following article are the reason behind the creation of new genetic information inside cells.
Coevolution is the relationship between two species where evolutionary changes of one species are influenced by evolutionary changes of the other. Examples of coevolution include the interactions between predator and prey or parasite and host.
Origins
Species (groups which can interbreed) change through a series of natural changes in their offspring's traits. These changes can be caused by various factors, including natural selection, gene drift, and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, such as climate changes or competition for food and habitat, can slow or accelerate the process.
The Evolution site tracks the evolution of a variety of animal and plant groups through time, focusing on the major changes that took place in the evolution of each group's history. It also examines the evolution of humans and is a subject that is of particular interest to students.
Darwin's Origin was published in 1859, when just a few antediluvian fossils of humans were discovered. One of them was the infamous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was a year before the first edition of the Origin was published, it is highly unlikely that Darwin had ever heard of it.
While the site focuses on biology, it contains a wealth of information on geology and paleontology. The Web site has a number of features that are especially impressive, such as an overview of how geological and climate conditions have changed over the course of time. It also features a map showing the distribution of fossil groups.
Although the site is a companion to the PBS television series however, it can stand on its own as a valuable source for 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 facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler’s experiments with guppies. They illustrate 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, the study of these creatures in their geological environment is a superior method of study over modern observational or research methods for exploring evolutionary phenomena. In addition to studying processes and events that take place frequently or over a long period of time, paleobiology is able to study the diversity of species of organisms and their distribution in space over geological time.
The site is divided into various options to study the subject of evolution. One of the paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The path also examines myths about evolution, and also the history of evolutionary thought.
Each of the main sections on the Evolution website is equally well-designed, with materials that are suited to a variety of educational levels and teaching styles. The site offers a wide array of multimedia and interactive resources, including videos, animations, and virtual labs, in addition to its general textual content. The breadcrumb-like arrangement of the content helps with navigation and orientation on the vast Web site.
For instance, the page "Coral Reef Connections" provides an overview of coral relationships and their interactions with other organisms. Then, it zooms in on a single clam that can communicate with its neighbors and react to changes in water conditions that occur at the level of the reef. This page, as well as the other multidisciplinary multimedia and interactive pages, offers a great introduction to many 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 for understanding the evolution of changes.
Evolutionary Theory
For biology students the concept of evolution is a major thread that binds all the branches of the field. A rich collection of resources supports teaching about evolution across the life sciences.
One resource, the companion to PBS's television series Understanding Evolution is an excellent example of an Web page that provides the depth and the wide range of educational resources. The site has a wide array of interactive learning modules. It also features a "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 connected to the realms 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 resource that is worth mentioning is the Evolution Library on this Web website, which includes an extensive library of multimedia items related to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives outlined in the standards for biology. It includes seven short videos that are designed for use in classrooms. These can be streamed or purchased as DVDs.
Evolutionary biology remains a field of study that has many important questions, such as what causes evolution and how fast it takes place. This is especially applicable to human evolution where it has been difficult to reconcile that the physical traits of humans were derived from apes with religions that believe that humans are unique among living things and has an exclusive place in the creation, with a soul.
There are a myriad of other ways evolution can occur including natural selection, which is the most widely accepted theory. Scientists also study other kinds like mutation, genetic drift and sexual selection.
While many scientific fields of inquiry have a conflict with literal interpretations of religious texts evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, while others haven't.
