Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science nonsense has led people to think that biologists don't believe in evolution.
This site, which is a companion to the PBS program, provides teachers with materials which support evolution education, while avoiding the kinds of misconceptions that can hinder it. It's laid out in the "bread crumb" format to make navigation and orientation easier.
Definitions
Evolution is a complicated and difficult subject matter to teach well. Many non-scientists are unable to grasp the concept, and some scientists even employ a definition that confuses it. This is especially relevant when it comes to the meaning of the words themselves.
It is therefore crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful manner. The site is both a companion for the 2001 series, but it is also a resource on its own. The material is presented in a way which aids navigation and orientation.
The site defines terms like common ancestor, gradual process and so on. These terms help to frame the nature of evolution as well as its relation to other scientific concepts. The site also provides an overview of how the concept of evolution has been vetted and validated. This information can help dispel myths that are created by the creationists.
에볼루션 블랙잭 can also access a glossary that contains terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to become better suited to an environment. This is the result of natural selection. It occurs when organisms that have more adaptable traits are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor (also called common ancestor) The most recent ancestor that is shared by two or more species. The common ancestor can be identified by analyzing the DNA of these species.
에볼루션 바카라사이트 : A large biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the cause of new genetic information in cells.
Coevolution: A relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be observed through the interaction between predator and prey, or parasite and hosts.
Origins
Species (groups that can interbreed) develop through a series of natural changes in the traits of their offspring. 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 or habitat can slow or speed up the process.
The Evolution site tracks through time the emergence of various animal and plant groups with a focus on major changes in each group's history. It also focuses on human evolution and is a subject that is particularly important to students.
Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans had been found. The most famous among them was the skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap when it was published in 1858, which was a year after the publication of the first edition of The Origin.
While the site focuses on biology, it includes a good deal of information about geology and paleontology. The most impressive features on the site are a series of timelines which show how geological and climatic conditions have changed over time, and an interactive map of the distribution of some fossil groups listed on the site.
The site is a companion to a PBS TV series but it can also be used as an educational resource by teachers and students. The site is well-organized and offers easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features of the museum website. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies, which illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has produced an array of plants, animals and insects. Paleobiology is the study of these creatures within their geological environment, has many advantages over modern observational or research methods of studying evolutionary phenomena. Paleobiology focuses on not just the processes and events that take place regularly or over time, but also the distribution and frequency of different groups of animals in space over the course of geological time.
The website is divided into various ways to learn about evolution that include "Evolution 101," which takes the viewer on a liner path through the scientific process and the evidence that supports the theory of evolution. The path also explores common misconceptions about evolution as well as the evolution of thought.
Each of the other major sections of the Evolution site is equally constructed, with materials that can support a variety of different pedagogical levels and curriculum levels. In addition to the standard textual content, the site features an extensive selection of interactive and multimedia resources, such as videos, animations, and virtual laboratories. The content is presented in a nested bread crumb style that facilitates navigation and orientation on the web site.
The page "Coral Reef Connections" For instance, it provides an overview of the coral's relationships and their interactions with other organisms, and then is enlarged to show one clam that is able communicate with its neighbours and respond to changes in water conditions that occur on the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, offers a great introduction to the many areas of evolutionary biology. The content includes an explanation of the role of natural selectivity and the concept of phylogenetics which is a crucial tool to understand evolutionary changes.
Evolutionary Theory
Evolution is an underlying thread that is found throughout all branches of biology. A rich collection of resources supports teaching about evolution across the life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that offers both depth and a variety of educational resources. The site features a wealth of interactive learning modules. It also has an encased "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this large Web site closer to the world of research science. For instance an animation that explains the idea of genetic inheritance connects to a page that focuses on John Endler's artificial selection experiments with guppies in native ponds of Trinidad.
Another helpful resource is the Evolution Library on this web site, which contains an extensive collection of multimedia assets that are related to evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives outlined in the biology standards. It contains seven videos designed specifically for classroom use, which can be streamed for free or purchased on DVD.
A variety of crucial questions remain in the midst of evolutionary biology, including the factors that trigger evolution and the speed at which it occurs. This is particularly relevant for the evolution of humans where it was a challenge to reconcile religious beliefs that humans have a distinct position in the universe and a soul with the notion that human beings have innate physical traits originated from Apes.
Additionally, there are a number of ways that evolution can occur and natural selection is 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 fields of scientific study conflict with literal interpretations found in religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, other religions haven't.
