Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution remain. Pop science nonsense has led many people to think that biologists don't believe in evolution.
This rich Web site - companion to the PBS series - provides teachers with materials that support evolution education and avoids the kinds of misconceptions that hinder it. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
It's not easy to effectively teach evolution. It is often misunderstood by non-scientists and even scientists are guilty of using a definition that confuses the issue. This is especially true when discussing the definition of the words.
Therefore, it is important to define terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful manner. The website is a companion to the series that first aired in 2001, but also functions as an independent resource. The content is presented in a nested manner that assists in navigation and orientation.
The site defines terms such as common ancestor and the gradual process. These terms help frame the nature of evolution as well as its relationship to other concepts in science. The site gives a comprehensive overview of the way the concept of evolution has been examined. This information will help to dispel the myths created by creationists.
It is also possible to get the glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable characteristics to become more suitable to a particular setting. This is a result of natural selection. It occurs when organisms with more adaptable characteristics are more likely to survive and reproduce than those with less adapted traits.
Common ancestor (also called common ancestor) The most recent ancestor shared by two or more species. By analyzing DNA from these species it is possible to identify the common ancestor.
Deoxyribonucleic acid: A huge biological molecule that contains the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
Coevolution is a relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be observed through the interaction between predator and prey, or parasites and hosts.
Origins
Species (groups of individuals that can interbreed) evolve through a series of natural changes in the traits of their offspring. These changes can be caused by various factors, including natural selection, gene drift, and mixing of the gene pool. The evolution of new species can take thousands of years. 에볼루션 바카라 사이트 , such as climate change or competition for food and habitat, can slow or accelerate the process.
The Evolution site tracks the evolution of a number of different groups of animals and plants over time, focusing on the major transitions that occurred in each group's history. It also explores the evolutionary history of humans, a topic that is crucial for students to comprehend.
Darwin's Origin was written in 1859, when only a handful of antediluvian fossils of humans were discovered. One of them was the infamous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was one year after the first edition of the Origin was published, it's extremely unlikely that Darwin had seen or heard of it.
While the site is focused on biology, it also includes a good deal of information on geology and paleontology. One of the most appealing features on the site are a series of timelines which show how climatic and geological conditions have changed over time as well as an interactive map of the geographical distribution of some fossil groups listed on the site.
Although the site is a companion to the PBS television series however, it can stand on its own as an excellent resource for teachers and students. The site is well-organized and has 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's web site. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are hyperlinks to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has produced an array of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment and has many advantages over the modern observational and research methods of examining evolutionary processes. Paleobiology is able to study not only the process and events that occur regularly or over time, but also the relative abundance and distribution of different species of animals in space throughout the geological time.
The website is divided into various paths that can be chosen to study the subject of evolution. One of the paths, "Evolution 101," guides the user through the nature and evidence of evolution. The path also explores misconceptions about evolution, and the background of evolutionary thought.
Each of the other major sections of the Evolution site is equally well created, with resources that can be used to support a range of different pedagogical levels and curriculum levels. In addition to the standard textual content, the site offers an array of interactive and multimedia resources, such as videos, animations, and virtual labs. The content is presented 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 the relationships between corals and their interactions with other organisms. Then, it narrows down to a single clam that is able to communicate with its neighbors and react to changes in the water conditions that take place at the level of the reef. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The material includes a discussion on the significance of natural selectivity and the concept of phylogenetics as a key tool to understand evolutionary change.
Evolutionary Theory
Evolution is a common thread that is found throughout all branches of biology. A vast collection of resources helps teachers teach about evolution across the life sciences.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that offers both the depth and the broadness in terms of educational resources. The site has a wide array of interactive learning modules. It also has an encased "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this massive website that are more closely tied to the field of research science. Animation that introduces the concept of genetics links to a page that highlights John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.
The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized according to 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 specifically designed for classroom use, which can be streamed at no cost or purchased on DVD.
Evolutionary biology is still an area of study with a lot of important questions to answer, such as the causes of evolution and the speed at which it takes place. This is particularly true for human evolution, which has made it difficult to reconcile the notion that the innate physical characteristics of humans derived from apes, and the religious beliefs that hold that humanity is unique in the universe and has an enviable place in creation, with a soul.
There are also a number of other ways in which evolution can take place and natural selection being the most widely accepted theory. Scientists also study other types like mutation, genetic drift, and sexual selection.
While 에볼루션 바카라 무료 of study have a conflict with the literal interpretations of religious texts, evolution biology has been a source of intense debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, others aren't.
