How To Recognize The Evolution Site That's Right For You
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions persist about evolution. People who have taken in pop science nonsense often assume that biologists claim they do not believe in evolution.
무료 에볼루션 - companion to the PBS series It provides teachers with materials that support evolution education and avoids the kinds of myths that hinder it. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
It's difficult to effectively teach evolution. Many non-scientists are unable to grasp the concept and some scientists use a definition which confuses it. This is particularly relevant when discussing the nature of the words themselves.
Therefore, it is important to define terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a simple and efficient manner. The website is a companion to the show that premiered in 2001, but it also functions as an independent resource. The material is presented in a structured manner that makes it simpler to navigate and understand.
The site defines terms such as common ancestor and gradual process. These terms help to define the nature of evolution and its relationship to other concepts in science. The site provides an overview of the manner the concept of evolution has been tested. 에볼루션 무료 바카라 can help dispel the myths created by creationists.
It is also possible to access a glossary of terms used in evolutionary biology. These terms include:
Adaptation is the process of changing hereditary traits to become more suited to the environment. This is a result of natural selection. Organisms with better-adapted traits are more likely than those with less adaptable traits to reproduce and survive.
무료에볼루션 (also known as common ancestor) is the most recent ancestor shared by two or more species. By studying the DNA of these species, it is possible to determine the common ancestor.
Deoxyribonucleic acid: A large biological molecule that holds the information needed for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are responsible for the creation of new genetic information within cells.
Coevolution is a relation between two species in which the evolutionary changes of one species influence evolutionary changes of the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts.
Origins
Species (groups of individuals that are able to interbreed) evolve through an array of natural changes in the traits of their offspring. The changes can be caused by a variety of factors that include natural selection, genetic drift and mixing of genes. The development of a new species may take thousands of years and the process could be slowed or increased by environmental conditions such as climate change or the competition for food or habitat.
The Evolution site tracks the evolution of various animal and plant groups through time and focuses on the most significant changes that took place in each group's history. It also focuses on the evolutionary history of humans and humans, a subject that is crucial for students to know.
Darwin's Origin was published in 1859, when just a handful of antediluvian fossils of humans were discovered. The famous skullcap, along with the bones that accompanied it, was 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, just 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 one of biology however, it also has many details on paleontology and geology. The most impressive features of the Web site are a set of timelines that show the way in which climatic and geological conditions have changed over time, as well as an outline of the distribution of a few fossil groups that are featured on the site.
The site is a companion to the PBS television series, but it can be used as a resource by teachers and students. The site is well organized and provides clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized components of the museum's Web site. These links facilitate the transition 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. They illustrate the importance ecology in evolutionary theory.
Diversity
The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology, the study of these creatures in their geological environment offers many advantages over modern observational or research methods of studying evolutionary phenomena. Paleobiology can examine not only the process and events that take place regularly or over time but also the distribution and frequency of different species of animals in space over the course of geological time.
The site is divided into various ways to learn about evolution that include "Evolution 101," which takes the viewer on a line through the nature of science and the evidence that supports the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought.
Each of the main sections of the Evolution website is equally well-developed, with materials that can be used to support a variety of levels of curriculum and teaching methods. The site includes a variety of multimedia and interactive resources which include animations, video clips and virtual laboratories, in addition to its general textual content. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the large web site.
For example the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms, then narrows down to a single clam that can communicate with its neighbors and react to changes in water conditions at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to the many areas of evolutionary biology. The content also includes an overview of the role of natural selectivity and the concept phylogenetics analysis, an important method for understanding the evolution of change.
Evolutionary Theory
For biology students evolution is a crucial thread that connects all branches of the field. A wide range of resources supports teaching about evolution across all life sciences.
One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that provides depth and breadth in terms of its educational resources. The site features a wide range of interactive learning modules. It also features an encased "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely tied to the field of research science. For instance an animation that explains the concept of genetic inheritance links to a page that highlights John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.
Another helpful resource is the Evolution Library on this site, which contains an extensive library of multimedia items that are related to evolution. The contents are organized into curriculum-based paths that parallel the learning objectives outlined in the standards for biology. It contains seven videos designed for use in classrooms. These can be viewed online or purchased as DVDs.
Evolutionary biology is an area of study that has many important questions, including what triggers evolution and how quickly it occurs. This is particularly true in the case of human evolution where it was a challenge to reconcile religious beliefs that held that humans have a distinct position in the universe and a soul, with the idea that innate physical traits were derived from Apes.
There are a variety of other ways in which evolution can occur and natural selection being the most widely accepted theory. Scientists also study other kinds like mutation, genetic drift and sexual selection.
Although many scientific fields of study have a conflict with literal interpretations in religious texts, evolution biology has been a subject 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.
