The Full Guide To Evolution Site
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution persist. People who have taken in popular science myths often assume that biologists don't believe in evolution.
This rich Web site - companion to the PBS series It provides teachers with materials which support evolution education and avoids the kinds of myths that make it difficult to understand. It's laid out in the "bread crumb" format to aid in navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach well. It is often misunderstood by non-scientists and even scientists use definitions that confuse the issue. This is particularly relevant to debates about the meaning of the word itself.
It is therefore essential to define the 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 on its own. The information is presented in an organized way that makes it easy to navigate and understand.
The site defines terms such as common ancestor, gradual process and so on. These terms help to frame the nature of evolution and 에볼루션바카라 its relation to other scientific concepts. The website then provides an overview of how the concept of evolution has been vetted and verified. This information can help dispel myths created by creationists.
It is also possible to get a glossary of terms used in evolutionary biology. These terms include:
Adaptation is the tendency of heritable traits to become better suited to an environment. This is a result of natural selection. It occurs when organisms with better adapted characteristics are more likely to survive and reproduce than those with less adaptable characteristics.
Common ancestor: The most recent common ancestor of two or more distinct species. By studying the DNA of these species, it is possible to determine the common ancestor.
Deoxyribonucleic Acid: A massive biological molecular that holds the information required for cell replication. The information is stored in nucleotide sequences, which are strung into long chains called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
Coevolution: A relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be seen in the interactions between predator and prey, or parasites and hosts.
Origins
Species (groups that can crossbreed), evolve through a series natural changes in their offspring's traits. These changes are caused by a variety of causes that include natural selection, genetic drift, and mixing of gene pools. The evolution of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food resources and habitat can impede or accelerate the process.
The Evolution site follows the emergence of various species of plants and animals and focuses on major changes within each group's past. It also explores the human evolutionary roots and humans, a subject that is especially important for students to know.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The famous skullcap, along with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap when it was published in 1858, one year following the initial edition of The Origin.
While the site focuses on biology, it contains a wealth of information on geology and paleontology. The most impressive features on the site are a timeline of events that illustrate the way in which climatic and geological conditions have changed over time, and a map of the distribution of some of the fossil groups featured on the site.
While the site is a companion piece to a PBS television show, it also stands on its own as an excellent resource for teachers and students. The site is well organized and provides clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These hyperlinks help users move from the enthralling cartoon 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, which illustrate 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 natural environment and has many advantages over the current observational and experimental methods for analyzing evolutionary processes. Paleobiology is able to study not only processes and events that take place frequently or over time, but also the distribution and frequency of different species of animals across the geological time.
The site is divided into several optional pathways to understanding evolution that include "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 common misconceptions about evolution as well as the evolution theory's history.
Each of the other sections of the Evolution site is equally developed, 에볼루션 바카라 무료 무료 에볼루션 바카라 에볼루션 [just click the next website page] with materials that can support a variety of educational levels and pedagogical styles. The site offers a wide array of interactive and multimedia resources that include animations, video clips and virtual laboratories as well as general textual content. The content is laid out in a nested bread crumb style that facilitates navigation and orientation within the large Web site.
For instance the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms. Then, it narrows down to a single clam that can communicate with its neighbors and react to changes in the water conditions at the level of the reef. This page, along with the other multidisciplinary multimedia and interactive pages, offers a great introduction to the many areas of evolutionary biology. The content includes a discussion on the role of natural selectivity and the concept of phylogenetics analysis as a key method for understanding the evolution of change.
Evolutionary Theory
For biology students evolution is a crucial thread that weaves together all branches of the field. A wide range of resources supports teaching about evolution across the life sciences.
One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both depth and a variety of educational resources. The site features a wealth of interactive learning modules. It also has a nested "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the world of research science. For example, an animation introducing the concept of genetic inheritance links to a page highlighting John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.
The Evolution Library on this website contains a large multimedia library of materials that deal to evolution. The content is organized into courses that are based on curriculum and follow the learning objectives outlined in the standards for biology. It contains seven short videos designed for classroom use. They can be streamed or purchased as DVDs.
A variety of crucial questions remain at the heart of evolutionary biology, such as the factors that trigger evolution and 에볼루션 슬롯게임 the speed at which it occurs. This is particularly relevant to human evolution, where it's been difficult to reconcile the notion that the physical characteristics of humans were derived from apes, and the religions that believe that humanity is unique among living things and holds a an enviable place in creation. It is soul.
There are a myriad of other ways in which evolution can occur including natural selection, which is the most well-known theory. Scientists also study other kinds such as mutation, genetic drift and sexual selection.
While many scientific fields of inquiry have a conflict with the literal interpretations of religious texts, evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, while others haven't.
