15 Amazing Facts About Evolution Site That You Didn t Know
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science fiction has led a lot of people to believe that biologists aren't believers in evolution.
This rich Web site, which is a companion to the PBS program offers teachers resources that promote evolution education while avoiding the types of misconceptions that hinder it. It's laid out in a "bread crumb" format to aid in navigation and orientation.
Definitions
Evolution is a complicated and challenging subject to teach effectively. 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.
It is therefore crucial to define the terms used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful way. The site is a companion site to the show which first aired in 2001, but also functions as an independent resource. The content is presented in a nested fashion which aids navigation and orientation.
The site defines terms such as common ancestor, gradual process and so on. These terms help define the nature and relationship of evolution to other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and verified. This information can help dispel myths created by creationists.
It is also possible to access a glossary of terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to become more suited to the environment. This is the result of natural selection, which happens when organisms with better adapted traits are more likely to survive and reproduce than those with less adapted traits.
Common ancestor: The most recent common ancestor of two or more distinct species. By analyzing the DNA from these species, it is possible to determine 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 known 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 influenced by evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or parasite and host.
Origins
Species (groups of individuals that can interbreed) change through an array of natural changes in the characteristics of their offspring. The changes can be caused by a variety, including natural selection, genetic drift and mixing of genes. The development of new species can take thousands of years. Environmental conditions, like changes in the climate or competition for food or habitat can slow or speed up the process.
The Evolution site follows the evolution of various species of plants and animals with a focus on major changes in each group's past. It also focuses on human evolution as a subject that is of particular interest to students.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The famous skullcap, with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was one year before the first edition of the Origin was published, it's highly unlikely that Darwin had seen or heard of it.
The site is mostly one of biology however it also includes lots of information about geology and paleontology. Among the best features on the site are a set of timelines that illustrate how geological and climatic conditions have changed over time, as well as a map of the distribution of a few fossil groups listed on the site.
The site is a companion for a PBS television series, but it can also be used as a resource by teachers and students. The site is well-organized and provides easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features of the museum's website. These hyperlinks make it easy to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler’s experiments with guppies, which illustrate the importance ecology in evolutionary theory.
Diversity
The evolution of life has produced many species of animals, 바카라 에볼루션 게이밍 (www.fridaycreative.co.uk) plants and 에볼루션코리아 insects. Paleobiology is the study of these creatures within their geological context and has a number of advantages over the modern observational and research methods of examining evolutionary phenomena. Paleobiology can examine not only processes and events that occur regularly or over time but also the relative abundance and distribution of different species of animals across geological time.
The site is divided into several optional ways to learn about 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 and 에볼루션카지노 the evolution theory's history.
Each of the main sections on the Evolution website is equally well-developed, with materials that are suited to a variety of curriculum levels and teaching styles. In addition to the standard textual content, the site also has an extensive selection of multimedia and interactive resources, such as videos, animations, and virtual laboratories. The breadcrumb-like organization of the content assists with navigation and orientation on the large web site.
For instance, the page "Coral Reef Connections" provides an overview of coral relationships and their interaction with other organisms, then zooms in on a single clam that can communicate with its neighbors and react to changes in water conditions that take place at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to the broad spectrum of topics in evolutionary biology. The information also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis, which is an important method to understand evolutionary change.
Evolutionary Theory
Evolution is an underlying thread that connects all branches of biology. A wide selection of resources helps teachers teach evolution across all life science disciplines.
One resource, the companion to PBS's television series Understanding Evolution is an excellent example of a Web site that provides the depth and the broadness in terms 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 closer to the field of research science. For example an animation that introduces the notion of genetic inheritance leads to a page that highlights John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.
The Evolution Library on this website has a huge multimedia library of resources that are associated with evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives set out in the standards for biology. It contains seven videos specifically designed for use in classrooms. They can be viewed online or purchased as DVDs.
Many important questions remain in the midst of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is particularly true in the case of human evolution which was a challenge to reconcile religious beliefs that humans have a distinct place in creation and a soul, with the idea that innate physical traits were derived from the apes.
There are a myriad of other ways in which evolution could occur including natural selection, which is the most widely accepted theory. Scientists also study different types such as genetic drift, and 바카라 에볼루션 sexual selection.
While many fields of scientific study are in conflict with literal interpretations found in religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, others have not.
