Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution persist. Pop science nonsense has led many people to believe that biologists don't believe evolution.
This site, which is a companion to the PBS program, provides teachers with materials that promote evolution education while avoiding the types of misconceptions that can hinder it. It's laid out in the "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complicated and difficult subject to teach well. It is often misunderstood even by non-scientists, and even some scientists have been guilty of using a definition that confuses the issue. This is especially true when discussing the meaning of the words themselves.
It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site serves as a companion for the 2001 series, but also a resource on its own. The material is presented in a nested fashion that assists in navigation and orientation.
The site defines terms like common ancestor (or common ancestor), gradual process and adaptation. These terms help define the nature of evolution and its relationship to evolution to other concepts in science. The website provides a summary of the manner in which evolution has been examined. This information can be used to dispel misconceptions that have been engendered by creationists.
You can also access a glossary which contains terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to become more suitable to their environment. This is the result of natural selection. Organisms with better-adapted characteristics are more likely than those with less-adapted traits to survive and reproduce.
Common ancestor (also called common ancestor) is the most recent ancestor that is shared by two or more species. By studying the DNA of these species, it is possible to identify the common ancestor.
Deoxyribonucleic Acid: A huge biological molecular that contains the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains called chromosomes. 에볼루션바카라사이트 are the basis for new genetic information in cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution are the interactions between predator and prey, or the parasite and the host.
Origins
Species (groups of individuals that are able to interbreed) develop through a series of natural changes in the traits of their offspring. The changes can be caused by a variety that include natural selection, genetic drift and mixing of gene pools. The evolution of new species could take thousands of years. Environmental conditions, such as changes in the climate or competition for food or habitat can slow or speed up the process.
The Evolution site tracks the development of various groups of animals and plants over time, focusing on the major shifts that occurred throughout the history of each group. It also examines the human evolutionary roots which is especially important for students to know.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The famous skullcap, with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year before the first edition of the Origin was published, it is extremely unlikely that Darwin had seen or heard of it.
에볼루션바카라사이트 is primarily one of biology however it also includes many details on paleontology and geology. The Web site has a number of features that are particularly impressive, including an overview of how geological and climate conditions have changed over the course of time. It also has maps that show the locations of fossil groups.
Although the site is a companion piece to the PBS television series however, it can stand on its own as an excellent source for teachers and students. The site is well-organized and provides clear links to the introduction content of Understanding Evolution (developed under the National Science Foundation's support) and the more specific features of the museum's website. These hyperlinks help users move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are hyperlinks to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has led to a wide variety of animals, plants, and insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over the modern observational and research methods for analyzing evolutionary phenomena. Paleobiology can examine not just the processes and events that happen regularly or over time but also the distribution and frequency of various animal groups in space over the course of the geological time.
The website is divided into several optional pathways to understanding evolution which include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence to support the theory of evolution. The path also explores common misconceptions about evolution as well as the evolution theory's history.
Each of the other major sections of the Evolution site is equally created, with resources that can support a variety of educational levels and pedagogical styles. In addition to the standard textual content, the site offers a wide range of multimedia and interactive content, such as videos, animations, and virtual laboratories. The breadcrumb-like structure of the content helps with navigation and orientation on the vast web site.
The page "Coral Reef Connections", for example, gives a brief overview of coral relationships and interactions with other organisms and then is enlarged to show one clam that is able to communicate with its neighbors and respond to changes in the conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to a variety of topics in evolutionary biology. The content also includes a discussion on the significance of natural selectivity and the concept phylogenetics analysis which is a crucial tool to understand evolutionary changes.

For biology students the concept of evolution is a major thread that weaves together all the branches of the field. A rich collection supports teaching evolution across all life science disciplines.
One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of a Web site that provides depth and wide range of educational resources. The site offers a range of interactive learning modules. It also has an encased "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. For example an animation that introduces the notion of genetic inheritance leads to a page that highlights John Endler's artificial selection experiments with guppies in native ponds of Trinidad.
Another useful resource is the Evolution Library on this Web website, which includes an extensive multimedia library of assets connected to evolution. The content is organized into curricula-based paths that correspond to the learning goals set forth in biology standards. It contains seven videos specifically designed for classroom use. They are available to stream or purchase as DVDs.
Many important questions remain at the core of evolutionary biology, including what triggers evolution and how fast it happens. This is particularly applicable to human evolution which has made it difficult to reconcile that the innate physical characteristics of humans derived from apes with religious beliefs that claim that humans are unique among living things and holds a a special place in creation. It is a soul.
There are also a number of other ways evolution can occur and natural selection being the most well-known theory. Scientists also study other types such as genetic drift, and sexual selection.
Although many scientific fields of study have a conflict with literal interpretations found in religious texts, evolution biology has been a source of intense controversy and opposition from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, but others haven't.
