Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, there are still a lot of misconceptions about evolution. People who have absorbed pop science nonsense often assume that biologists are saying they 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 that can undermine it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach well. It is often misunderstood even by non-scientists, and even scientists are guilty of using an interpretation that is confusing the issue. This is especially true when it comes to discussions 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 site to the show that premiered in 2001, but it is also an independent resource. The material is presented in a nested fashion that assists in navigation and orientation.
에볼루션 바카라사이트 defines terms such as common ancestor, gradual process and so on. These terms help to define the nature of evolution as well as its relationship to other scientific concepts. The site then offers an overview of how the concept of evolution has been tested and confirmed. This information can be used to dispel the myths that have been created by creationists.
You can also consult a glossary that contains terms used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to be more suited to the environment. This is the result of natural selection, which happens when organisms that have more adaptable characteristics are more likely to survive and reproduce than those with less adapted traits.
Common ancestor (also known as common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of these species.
에볼루션 바카라사이트 : A large biological molecular containing the necessary information for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are responsible for the creation of new genetic information within cells.
Coevolution is the relationship between two species where evolution of one species are influenced by evolutionary changes in the other. Coevolution can be seen in the interactions between predator and prey, or parasites and hosts.
Origins
Species (groups that can crossbreed) change through a series natural changes in their offspring's traits. The changes can be caused by a variety of factors that include natural selection, genetic drift and mixing of genes. The evolution of new species can take thousands of years. Environmental circumstances, such as climate change or competition for food or habitat can impede or accelerate 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 past. It also examines the evolution of humans as a subject of particular importance for students.
Darwin's Origin was written in 1859, when only a few antediluvian fossils of human beings had been discovered. One of them was the infamous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap when it was published in 1858, which was a year after the first edition of The Origin. Origin.
The site is primarily one of biology however it also includes many details on geology and paleontology. Among the best features of the Web site are a series of timelines that show how climatic and geological conditions have changed over time as well as an interactive map of the distribution of some of the fossil groups featured on the site.
Although the site is a companion to a PBS television series, it also stands on its own as an excellent source for teachers and students. The site is very well organized and provides clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum Web site. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a variety of animals, plants and insects. Paleobiology, the study of these creatures in their natural environment is a superior method of study over modern observational or experimental methods for studying evolutionary processes. click hyperlink is able to study 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 Web site is divided into several optional paths to learning evolution which include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence to support the theory of evolution. The path also explores misconceptions regarding evolution, and the background of evolutionary thought.
Each of the main sections on the Evolution website is equally well-developed, and includes materials that are suited to a variety of levels of curriculum and teaching methods. The site includes a variety of interactive and multimedia resources that include animations, video clips and virtual labs as well as general textual content. The content is organized in a nested, bread crumb fashion that aids navigation and orientation within the vast web site.
The page "Coral Reef Connections" For instance, it provides a comprehensive overview of the coral's relationships and interactions with other organisms and then zooms in on one clam that is able communicate with its neighbours and respond to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a key method to understand evolutionary changes.
Evolutionary Theory
For biology students the concept of evolution is a major thread that binds all the branches of the field. A wide range of resources helps teachers teach about evolution across all life sciences.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that offers both depth and wide range of educational resources. The site offers a range of interactive learning modules. It also has an "bread crumb structure" that helps students move away from the cartoon style that is used in Understanding Evolution and onto elements on this large website more closely linked to the fields of research science. Animation that introduces the concept of genetics is linked to a page about John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.
The Evolution Library on this website has a huge multimedia library of resources that are associated to evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives set out in the standards for biology. It includes seven short videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.
Evolutionary biology is still an area of study that has many important questions, such as what triggers evolution and how fast it takes place. This is particularly applicable to human evolution where it's been difficult to reconcile the notion that the innate physical characteristics of humans evolved from apes, and the religions that believe that humanity is unique among living things and holds a a special place in creation. It is soul.
There are a myriad of other ways in which evolution could occur including natural selection, which is the most well-known theory. Scientists also study other kinds like mutation, genetic drift, and sexual selection.
While many scientific fields of inquiry are in conflict with literal interpretations of the Bible, evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
