Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution persist. People who have absorbed pop science nonsense often assume that biologists are saying they do not believe in evolution.
This site, which is a companion to the PBS program offers teachers resources that promote evolution education, while avoiding the kinds of misconceptions that make it difficult to understand. It's organized in the "bread crumb" format to make navigation and orientation easier.
Definitions
It's difficult to teach evolution well. It is often misunderstood by non-scientists and even some scientists are guilty of using definitions that confuse the issue. This is particularly relevant when it comes to the nature of the words themselves.
바카라 에볼루션 is essential to define terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. The site serves as a companion for the 2001 series, but also a resource of its own. The material is presented in an organized manner that makes it simpler to navigate and understand.
The site defines terms like common ancestor and the gradual process. These terms help to define the nature and relationship of evolution with other scientific concepts. The site then offers an overview of how the concept of evolution has been vetted and verified. This information can be used to dispel myths that have been created by creationists.
It is also possible to access the glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable traits to become better adaptable to a specific environment. This is a 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) The most recent ancestral ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of these species.
Deoxyribonucleic Acid: A large biological molecular that contains the necessary information for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.
Coevolution is a relationship between two species, where the evolution of one species influence evolutionary changes of the other. Coevolution can be seen in the interactions between predator and prey, or parasite and hosts.
Origins
Species (groups that can interbreed) develop by a series of natural variations in their offspring's traits. Changes can be caused by numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, such as climate change or competition for food resources and habitat can impede or accelerate the process.
The Evolution site tracks the development of a variety of species of plants and animals over time and focuses on the most significant shifts that occurred throughout each group's history. It also focuses on human evolution, which is a topic that is particularly important for students.
Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans had been found. One of them was the infamous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was first published in 1858, one year following the initial edition of The Origin.
While the site focuses on biology, it contains a wealth of information about geology and paleontology. The Web site has a number of aspects that are quite impressive, including the timeline of the way that climate and geological conditions have changed over time. It also has an interactive map that shows the location of fossil groups.
The site is a companion for a PBS television series, but it can also be used as a resource by teachers and students. The site is very well organized and provides clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized 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 also links to John Endler's experiments with guppies. They illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has produced many species of animals, plants and insects. Paleobiology is the study of these creatures in their geological context, has many advantages over modern observational or experimental methods for exploring evolutionary processes. Paleobiology is able to study not only the process and events that occur frequently or over time, but also the distribution and frequency of various animal groups across the geological time.
The website is divided into various paths to learning evolution which include "Evolution 101," which takes the viewer on a line through the science of nature and the evidence supporting the theory of evolution. The path also explores common misconceptions about evolution and the history of evolutionary thought.
Each of the other main sections of the Evolution site is equally well created, with resources that support a variety of curriculum levels and pedagogical styles. In addition to the standard textual content, the site features a wide range of multimedia and interactive resources like video clips, animations, and virtual laboratories. The breadcrumb-like structure of the content aids in navigation and orientation on the vast website.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides an overview of the coral's relationships, their interaction with other organisms and then zooms in on one clam that is able communicate with its neighbors and react to changes in conditions of the water at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, provides an excellent introduction to the many areas of evolutionary biology. The information also includes an overview of the importance of natural selection and the concept of phylogenetic analysis, which is a crucial tool in understanding evolutionary change.
Evolutionary Theory
Evolution is a common thread that is found throughout all branches of biology. A vast collection of resources supports teaching about evolution across the life sciences.
One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web site that provides depth and wide range of educational resources. The site has a variety of interactive learning modules. It also has a nested "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this huge site that are more closely linked to the field of research science. For example, an animation introducing 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 site, which contains an extensive library of multimedia resources connected to evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives outlined in the biology standards. It includes seven short videos designed for use in classrooms. These can be streamed or purchased as DVDs.
바카라 에볼루션 of important questions remain in the midst of evolutionary biology, such as what triggers evolution and how fast it happens. This is particularly true in the case of human evolution, where it was difficult to reconcile religious beliefs that held that humans have a distinct place in the creation and a soul with the notion that our physical traits were derived from the apes.
Additionally there are a myriad of ways in which evolution could be triggered, with natural selection being the most popular theory. However scientists also study other types of evolution such as mutation, genetic drift, and sexual selection, among others.
While many scientific fields of inquiry have a conflict with the literal interpretations of religious texts Evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, others aren't.
