15 Startling Facts About Evolution Site You ve Never Known
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions persist about evolution. Pop science fiction has led a lot of people to think that biologists don't believe in evolution.
This site, which is a complement to the PBS program that provides teachers with resources which support evolution education, while avoiding the kinds of misconceptions which undermine it. It's laid out in the "bread crumb" format to make navigation and orientation easier.
Definitions
Evolution is a complex and challenging subject to teach well. It is often misunderstood by non-scientists, and even scientists use definitions that confuse the issue. This is particularly true when it comes to debates about the definition of the word itself.
It is therefore crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient way. The site is a companion to the show which first aired in 2001, but it can also function as an independent resource. The material is presented in a nested manner that aids navigation and orientation.
The site defines terms such as common ancestor, gradual process and adaptation. These terms help to define the nature of evolution and its relationship to evolution with other scientific concepts. The site gives a comprehensive overview of the manner in which evolution has been examined. This information can help dispel myths created by creationists.
You can also consult a glossary that contains terms used in evolutionary biology. These terms include:
Adaptation is the tendency of hereditary traits to become more suited to the environment. This is a result of natural selection. Organisms with better-adapted characteristics are more likely than those with less-adapted traits to survive and reproduce.
Common ancestor (also called common ancestor) The most recent ancestor shared by two or more species. By analyzing the DNA from these species, it is possible to determine the common ancestor.
Deoxyribonucleic Acid: A massive biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences, which are strung into long chains, referred to as chromosomes. Mutations are the basis for new genetic information in cells.
Coevolution: 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 the parasite and the host.
Origins
Species (groups of individuals that can interbreed) develop through natural changes in the traits of their offspring. The changes can be triggered by a variety such as natural selection, genetic drift and mixing of gene pools. The evolution of a new species can take thousands of years, and the process could be slowed down or speeded up by environmental factors like climate change or competition for food or habitat.
The Evolution site traces through time the evolution of different groups of animals and plants and focuses on major changes in each group's past. It also explores the evolutionary origin of humans which is especially important for students to comprehend.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The famous skullcap, along with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, a year before the first edition of the Origin was published, it's extremely unlikely that Darwin had ever heard of it.
The site is primarily an online biology resource however, 무료에볼루션 게이밍 (head to Wikimapia) it also has lots of information about paleontology and geology. The site offers numerous aspects that are quite impressive, including an overview of the way that climate and geological conditions have changed over the course of time. It also includes an interactive map that shows the location of fossil groups.
The site is a companion for the PBS TV series but it can be used as a resource by teachers and students. The site is extremely well-organized and offers 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 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 ecology in evolutionary theory.
Diversity
The evolution of life has produced a variety of plants, animals and insects. Paleobiology is the study of these creatures within their geological environment is a superior method of study over modern observational or research methods of studying evolutionary phenomena. Paleobiology is able to study not only processes and events that take place regularly or over time, but also the distribution and frequency of various animal groups across the geological time.
The site is divided up into various paths that can be chosen to gain knowledge about evolution. One of these paths, "Evolution 101," walks the reader through the evolution of nature and the evidence of evolution. The path also explores the most common misconceptions about evolution, 무료에볼루션 as well as the history of evolutionary thought.
Each of the main sections on the Evolution website is equally well-developed, and includes materials that support a variety levels of curriculum and teaching methods. The site includes a variety of interactive and multimedia content, including animations, video clips and virtual labs as well as general textual content. The content is organized in a nested, 에볼루션 무료체험 bread crumb-like fashion that helps with navigation and orientation within the large web site.
The page "Coral Reef Connections", for example, provides a comprehensive overview of the relationships between corals and interactions with other organisms and zooms in to one clam, which can communicate with its neighbours and 바카라 에볼루션 respond to changes in the conditions of the water at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The material includes a discussion on the importance of natural selection and the concept of phylogenetics analysis which is a crucial tool for understanding evolutionary change.
Evolutionary Theory
Evolution is an underlying thread that connects all branches of biology. A rich collection supports teaching evolution across all life science disciplines.
One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both depth and breadth in its educational resources. The site has a wide array of interactive learning modules. It also has an encased "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this huge site that are more closely linked to the field of research science. An animation that introduces the concept of genetics links to a page highlighting John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.
Another helpful resource is the Evolution Library on this web site, which contains an extensive collection of multimedia assets related to evolution. The content is organized in curricula-based paths that correspond to the learning objectives set out in the standards for biology. It includes seven short videos designed specifically for use in the classroom, and can be streamed at no cost or purchased on DVD.
Many important questions remain at the heart of evolutionary biology, such as the factors that trigger evolution and the speed at which it occurs. This is particularly true for the evolution of humans where it was a challenge to reconcile religious beliefs that humanity has a special place in creation and a soul, with the notion that human beings have innate physical traits evolved from the apes.
There are a variety of other ways evolution can occur and 에볼루션바카라 natural selection being the most widely accepted theory. Scientists also study other kinds such as mutation, genetic drift, and sexual selection.
Many fields of inquiry have a conflict with the literal interpretations of the Bible evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
