5 Reasons Evolution Site Is Actually A Positive Thing
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions persist about evolution. People who have been exposed to pop science nonsense often assume that biologists don't believe in evolution.
This rich Web site - companion to the PBS series offers teachers with resources that promote evolution education and help avoid the kinds of misinformation that can undermine it. It's organized in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
Evolution is a complex and challenging subject to teach well. Many non-scientists are unable to grasp the concept, and some scientists even use a definition that confuses it. This is particularly relevant when discussing the definition of the words.
It is important to define terms that are used in evolutionary biology. The website for the PBS show, 에볼루션 바카라 Understanding Evolution, does this in a simple and efficient way. The site is both an accompaniment to the 2001 series, and also a resource on its own. The content is presented in a nested fashion that aids navigation and orientation.
The site defines terms like common ancestor and the gradual process. These terms help to define the nature of evolution and its relation to other scientific concepts. The site provides an overview of the way that evolution has been tested. This information can help dispel the myths created by creationists.
It is also possible to find the glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency of heritable characteristics to become more suitable to a particular setting. This is a result of natural selection, which happens when organisms that have more adaptable characteristics are more likely to survive and reproduce than those with less adapted traits.
Common ancestor: The latest common ancestor of two or more different species. The common ancestor can be identified by studying the DNA of those species.
Deoxyribonucleic acid: A huge biological molecule that contains information required for cell replication. The information is contained in a sequence of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the source of new genetic information within cells.
Coevolution is a relationship between two species, where the evolution of one species influence evolutionary changes in the other. Coevolution can be seen through the interaction between predator and prey, or parasite and hosts.
Origins
Species (groups which can interbreed) develop by a series of natural variations in their offspring's traits. These changes can be caused by many factors, such as 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 and habitat, can slow or accelerate the process.
The Evolution site traces through time the emergence of various animal and plant groups, focusing on major transitions in each group's past. It also focuses on the evolutionary origin of humans and humans, a subject that is particularly important for students to comprehend.
When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. The famous skullcap, with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was first published in 1858, which was a year after the publication of the first edition of The Origin.
The site is mostly an online biology resource however, it also has a lot of information on geology and paleontology. The most impressive features of the Web site are a timeline of events that illustrate the way in which climatic and geological conditions have changed over time and an interactive map of the distribution of a few of the fossil groups featured on the site.
Although the site is a companion to a PBS television show, it also stands on its own as an excellent resource for teachers and students. The site is extremely well-organized and offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum Web site. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds 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 on Earth has produced a diversity of animals, plants, and insects. Paleobiology, the study of these creatures within their natural environment, has many advantages over the current observational or experimental methods for exploring evolutionary processes. Paleobiology is able to study not just the processes and events that happen frequently or over time, but also the distribution and frequency of different groups of animals in space over the course of geological time.
The site is divided up into different paths that can be chosen to study the subject of evolution. One of these 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 history of evolutionary thought.
Each of the main sections on the Evolution website is equally well-designed, with materials that are suited to a variety of curriculum levels and 에볼루션 게이밍 에볼루션 카지노 사이트 (Cctvdgrw published a blog post) teaching styles. In addition to the general textual content, 에볼루션바카라사이트 (Fkwiki.Win) the site also has a wide range of multimedia and interactive resources like videos, animations and virtual labs. The content is presented 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, the page "Coral Reef Connections" provides a comprehensive overview of the coral's relationships and interactions with other organisms and is enlarged to show one clam, which is able to communicate with its neighbors and react to changes in conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a broad spectrum of topics in evolutionary biology. The material includes an overview of the importance of natural selection and the concept of phylogenetics as a key tool for understanding evolutionary change.
Evolutionary Theory
For biology students the concept of evolution is a major thread that connects all the branches of the field. A rich collection supports teaching evolution across all disciplines of life sciences.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web site that provides depth and wide range of educational resources. The site has a variety of interactive learning modules. It also has an encased "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this massive website that are more closely linked to the field of research science. An animation that introduces students to the concept of genetics links to a page highlighting John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.
Another useful resource is the Evolution Library on this web website, which includes an extensive library of multimedia resources connected to evolution. The content is organized into curriculum-based paths that parallel the learning objectives set out in the biology standards. It includes seven short videos specifically designed for classroom use, which can be streamed for no cost or purchased on DVD.
Evolutionary biology is still a field of study that has many important questions, such as the causes of evolution and how fast it happens. This is particularly relevant in the case of human evolution where it was a challenge to reconcile religious beliefs that held that humanity has a unique place in the creation and a soul, with the notion that human beings have innate physical traits evolved from Apes.
In addition there are a myriad of ways that evolution could occur, with natural selection being the most widely accepted theory. However scientists also study other types of evolution such as mutation, genetic drift and sexual selection, among other things.
While many scientific fields of inquiry are in conflict with literal interpretations of the Bible evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, but others haven't.
