Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution remain. Pop science nonsense has led many people to think that biologists don't believe in evolution.
This rich Web site,
에볼루션 바카라 which is a complement to the PBS program that provides teachers with resources that promote evolution education, while avoiding the kinds of misconceptions that hinder it. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
It's difficult to teach evolution well. Many non-scientists are unable to grasp the concept and some scientists use a definition which confuses it. This is particularly true when it comes to debates about the definition of the word itself.
It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. It is a companion for the 2001 series,
에볼루션사이트 but it is also a resource on its own. The material is presented in a structured manner that makes it simpler to navigate and understand.
The site defines terms like common ancestor, gradual process, and adaptation. These terms help define the nature and significance of evolution with other scientific concepts. The site gives a comprehensive overview of the manner that evolution has been tested. This information will help to dispel the myths that are created by the creationists.
It is also possible to get the glossary of terms used in evolutionary biology. These terms include:
Adaptation: 에볼루션게이밍 (
Khdesign.nehard.Kr) The tendency for hereditary traits to become more adaptable to a specific environment. This is a result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adaptable traits to reproduce and survive.
Common ancestor (also called common ancestor) The most recent ancestor that is shared by two or more species. By studying the DNA of these species, it is possible to determine the common ancestor.
Deoxyribonucleic Acid: A huge biological molecular that holds the information required for cell replication. The information is contained in nucleotides arranged in sequences 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 relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution is evident through the interaction between predator and prey, or parasites and hosts.
Origins
Species (groups that can interbreed) develop through a series natural changes in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The development of new species can take thousands of years. Environmental circumstances, such as climate changes or competition for food resources and habitat can impede or accelerate the process.
The Evolution site tracks the development of a number of different groups of animals and plants over time with a focus on the key shifts that occurred throughout each group's history. It also examines the evolution of humans as a subject of particular importance to students.
Darwin's Origin was published in 1859, at a time when only a few antediluvian fossils of humans had been found. The skullcap that is famous, along with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap when it was published in 1858, one year following the initial edition of The Origin.
The site is mostly an online biology resource, but it also contains a lot of information on geology and paleontology. Among the best features of the Web site are a series of timelines which show the way in which climatic and geological conditions have changed over time as well as a map of the geographical distribution of some fossil groups listed on the site.
Although the site is a companion to a PBS television show, it also stands on its own as an excellent source for teachers and students. The site is extremely well-organized and has clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are hyperlinks to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has produced a diversity of animals, plants, 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 for studying evolutionary phenomena. Paleobiology focuses on not just the processes and events that take place frequently or over time, but also the distribution and frequency of various animal groups in space over the course of geological time.
The website is divided into a variety of paths to learning evolution which include "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence that supports the theory of evolution. The path also examines myths regarding evolution, and the background of evolutionary thinking.
Each of the main sections on the Evolution website is equally well-designed,
에볼루션 룰렛 (

The site has a range of interactive and multimedia content, including video clips, animations and virtual labs as well as 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.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides an overview of the coral's relationships and interactions with other organisms and then is enlarged to show one clam,

This page, as well as the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to the broad range of topics in evolutionary biology. The content also includes an explanation of the significance of natural selectivity and the concept phylogenetics analysis which is a crucial tool to understand evolutionary change.
Evolutionary Theory
Evolution is an underlying thread that is found throughout all branches of biology. A rich collection supports teaching evolution across all 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 as well as broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also features an encased "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the field of research science. Animation that introduces the concept of genetics, which links to a page that highlights John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.
The Evolution Library on this website has a huge multimedia library of assets related to evolution. The content is organized according to curricula-based pathways that correspond to the learning objectives outlined in 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 remains an area of study that poses many important questions, such as the causes of evolution and how fast it takes place. This is particularly true for human evolution, where it's been difficult to reconcile the notion that the physical characteristics of humans evolved from apes and religious beliefs that hold that humanity is unique among living things and holds a a special place in creation, with a soul.
There are a myriad of other ways evolution could occur, with natural selection as the most widely accepted theory. However scientists also study different kinds of evolution, such as genetic drift, mutation, and sexual selection, among others.
While many scientific fields of inquiry conflict with the literal interpretations of the Bible evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the ideas of evolution, other religions aren't.
