7 Things You d Never Know About Evolution Site
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution persist. Pop science nonsense has led many people to believe that biologists aren't believers in evolution.
This site, which is a companion to the PBS series offers teachers with resources that support evolution education and help avoid the kinds of misconceptions that hinder it. It's organized in a "bread crumb" format to facilitate navigation and orientation.
Definitions
It's difficult to teach evolution well. It is often misunderstood by non-scientists and even some scientists use definitions that confuse the issue. This is especially relevant when it comes to the meaning of the words themselves.
Therefore, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The website is a companion to the show that premiered in 2001, but is also an independent resource. The content is presented in a nested fashion 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 website provides a summary of the way that evolution has been tested. This information can be used to dispel myths that have been engendered by the creationists.
You can also access a glossary that includes terms used in evolutionary biology. These terms include:
Adaptation is the process of changing hereditary traits to become more suitable to their environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less adapted traits to survive and reproduce.
Common ancestor: The latest common ancestor 에볼루션 바카라사이트 (http://wx.abcvote.Cn/) of two or more different species. The common ancestor can be identified through analyzing the DNA of these species.
Deoxyribonucleic acid: A massive biological molecule that contains the information needed for cell replication. The information is stored in nucleotide sequences, which 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 evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or the parasite and the host.
Origins
Species (groups which can interbreed) develop through a series of natural changes in their offspring's traits. These changes can be caused by various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, like climate change or competition for food or habitat can impede or accelerate the process.
The Evolution site tracks the development of a variety of groups of animals and plants over time with a focus on the key transitions that occurred in each group's history. It also focuses on the human evolutionary roots which is especially important for students to know.
When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. One of them was the infamous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, a year before the first edition of the Origin appeared, it is highly unlikely that Darwin had seen or heard of it.
While the site is focused on biology, it also contains a wealth of information about geology as well as paleontology. The Web site has a number of features that are especially impressive, such as an overview of how climate and geological conditions have changed over the course of time. It also includes a map showing the distribution of fossil groups.
The site is a companion to a PBS television series, but it could also be used as an educational source for teachers and students. The site is well organized and 에볼루션 바카라 무료 provides clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These hyperlinks help users move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's experiments with guppies that illustrate 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, the study of these creatures in their geological context, has many advantages over the current observational or experimental methods for studying evolutionary processes. In addition to studying processes and events that occur regularly or 에볼루션 블랙잭 over a long period of time, paleobiology is able to analyze the relative abundance of various groups of organisms and their distribution throughout the course of geological time.
The site is divided up into different routes that can be taken to learn about evolution. One of the paths, "Evolution 101," walks the reader through the nature and evidence of evolution. The path also explores common misconceptions about evolution as well as the evolution theory's history.
Each of the main sections of the Evolution website is equally well-designed, with materials that support a variety curriculum levels and teaching styles. The site includes a variety of interactive and multimedia content that include videos, animations, and virtual labs, in addition to its general textual content. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation within the large Web site.
The page "Coral Reef Connections" For instance, it gives a brief overview of coral relationships and their interactions with other organisms and is enlarged to show one clam, which can communicate with its neighbours and respond to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, provides an excellent introduction to a variety of topics in evolutionary biology. The material includes a discussion on the role of natural selectivity and the concept of phylogenetics analysis which is a crucial method for understanding the evolution of change.
Evolutionary Theory
For biology students, evolution is a key thread that connects all the branches of the field. A rich collection supports teaching evolution across the life science disciplines.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that offers both depth and breadth in terms of its 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, which links to a page that highlights John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.
Another helpful resource is the Evolution Library on this Web site, which contains an extensive multimedia library of assets connected to evolution. The content is organized into curricula-based paths that correspond to the learning objectives outlined in the standards for biology. It contains seven videos specifically designed for use in classrooms, 에볼루션 바카라 무료체험바카라사이트 - check out this one from Footballzaa, and can be streamed for free or purchased on DVD.
A variety of crucial questions remain in the midst of evolutionary biology, such as what causes evolution to occur and the speed at which it occurs. This is particularly true for humans' evolution where it was a challenge to reconcile religious beliefs that held that humanity has a special place in the creation and a soul with the idea that innate physical traits originated from Apes.
Additionally, there are a number of ways that evolution can be triggered and natural selection is the most popular theory. However scientists also study different kinds of evolution, such as genetic drift, mutation, and sexual selection, among other things.
Although many scientific fields of study conflict with the literal interpretations of religious texts, the concept of evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, other religions have not.
