Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution remain. People who have absorbed the nonsense of pop science often believe that biologists are saying they don't believe in evolution.
This site, which is a companion to the PBS series offers teachers with resources that support evolution education and avoid the kinds of misconceptions that undermine it. It's organized in the "bread crumb" format to aid in navigation and orientation.
Definitions
It is difficult to properly teach evolution. Many non-scientists are unable to grasp the concept, and some scientists even employ a definition that confuses it. This is particularly applicable to discussions on the nature of the word.
It is therefore important to define the terms used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient manner. The site serves as a companion for the 2001 series, and also a resource of its own. The content is presented in a nested manner which aids navigation and orientation.
The site defines terms such as common ancestor (or common ancestor), gradual process and adaptation. These terms help to define the nature and significance of evolution with other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and validated. This information can help dispel the myths created by creationists.
It is also possible to access a glossary of terms used in evolutionary biology. These terms include:
Adaptation is the tendency of heritable traits to be more suitable to their environment. This is a result of natural selection. Organisms with more adaptable traits are more likely than those with less adaptable characteristics to survive and reproduce.
Common ancestor: The most recent common ancestor of two or more species. The common ancestor can be identified by analyzing the DNA of these species.
Deoxyribonucleic Acid: A massive biological molecular that holds the necessary information for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are the cause of new genetic information in cells.
Coevolution is a relationship between two species where evolution of one species are influenced evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasites and hosts.
Origins
Species (groups of individuals that are able to interbreed) evolve through an array of natural changes in the characteristics of their offspring. These changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The evolution of a new species can take thousands of years and the process could be slowed or increased by environmental factors like climate change or competition for food or habitat.
The Evolution site traces the emergence of various species of plants and animals over time, focusing on the major changes that took place in each group's history. It also explores the evolutionary history of humans which is especially important for students to comprehend.
When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, a year before the first edition of the Origin was published, it is extremely unlikely that Darwin had seen or heard of it.
The site is primarily an online biology resource, but it also contains many details on paleontology and geology. The website has numerous features that are especially impressive, such as an overview of how climate and geological conditions have changed over the course of time. It also has maps that show the locations of fossil groups.
The site is a companion to the PBS TV series but it could be used as a resource for teachers and students. The site is well-organized, and provides clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features of the museum website. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. In particular, there are links to John Endler's experiments with Guppies, which 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 is the study of these creatures within their natural environment and has numerous advantages over the modern observational and research methods in its exploration of evolutionary processes. In addition to exploring the processes and events that happen frequently or over a long period of time, paleobiology can be used to examine the relative abundance of various species of organisms and their distribution across geological time.
The site is divided into several optional paths to learning evolution, including "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence supporting the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought.
Each of the main sections on the Evolution website is equally well-developed, and includes materials that are suited to a variety of curriculum levels and teaching styles. The site offers a wide array of interactive and multimedia resources that include video clips, animations and virtual labs as well as general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the vast website.
For 에볼루션 바카라사이트 " gives a brief overview of coral relationships and their interactions with other organisms. Then, it zooms in on a single clam that is able to communicate with its neighbors and respond to changes in water conditions 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 material also provides an overview of the importance of natural selection and the concept of phylogenetic analysis, which is a key method to understand evolutionary changes.
Evolutionary Theory
For biology students, evolution is a key thread that connects all branches of the field. A vast collection of resources supports teaching about evolution across all life sciences.
One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides depth and a variety of educational resources. The site features a wealth of interactive learning modules. It also features a nested "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the world of research science. Animation that introduces the concept of genetics is linked to a page that highlights John Endler's experiments with artificial selection using Guppies in native ponds in Trinidad.
The Evolution Library on this website contains a large multimedia library of resources that are associated to evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in biology standards. It includes seven short videos that are intended for use in the classroom. These can be streamed or purchased as DVDs.
Evolutionary biology is still an area of study with a lot of important questions, such as what causes evolution and how quickly it occurs. This is especially true for humans' evolution which was a challenge to reconcile religious beliefs that held that humanity has a special place in the creation and a soul with the notion that our physical traits were derived from Apes.
In addition there are a myriad of ways that evolution can be triggered and natural selection is the most widely accepted theory. Scientists also study other types such as genetic drift and sexual selection.
While many scientific fields of study have a conflict with literal interpretations found in religious texts, the concept of evolution biology has been a source of intense debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, other religions haven't.
