Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, misconceptions persist about the evolution. Pop science nonsense has led many people to think that biologists don't believe in evolution.
This site, which is a companion to the PBS series - provides teachers with materials which support evolution education and avoids the kinds of misinformation that can make it difficult to understand. It's organized in a "bread crumb" format to aid in navigation and orientation.
Definitions
It is difficult to effectively teach evolution. Many non-scientists are unable to grasp the concept, and some scientists even use a definition which confuses it. 에볼루션 슬롯 is particularly applicable to discussions about the meaning of the word itself.
Therefore, it is essential to define terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient manner. The site is a companion site to the series that first aired in 2001, but can also function as an independent resource. The material is organized in a manner that makes it easier to navigate and comprehend.
The site defines terms like common ancestor and gradual process. These terms help frame the nature of evolution and its relationship to other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and validated. This information can be used to dispel the myths that have been engendered by creationists.
You can also access 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 occurs when organisms that have more adaptable characteristics are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor (also known as common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified by analyzing the DNA of these species.
Deoxyribonucleic acid: A huge biological molecule that contains information required for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the basis for new genetic information within cells.
Coevolution is the relationship between two species where evolutionary changes of one species are influenced by evolutionary changes of the other. Coevolution can be seen through the interaction between predator and prey, or parasites and hosts.
Origins
Species (groups of individuals who can interbreed) evolve through a series of natural changes in the characteristics of their offspring. The causes of these changes are many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of a new species could 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 through time the evolution of various species of plants and animals and focuses on major changes in each group's history. It also explores the evolutionary history of humans and humans, a subject that is particularly important for students to understand.
Darwin's Origin was published in 1859, at a time when only a handful of antediluvian fossils of human beings had been discovered. One of them was the infamous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was a year before the first edition of the Origin was published, it is very unlikely that Darwin had ever heard of it.
While the site focuses on biology, it includes a good deal of information about geology and paleontology. The website has a number of features that are particularly impressive, including an overview of how climate and geological conditions have changed over time. It also has an interactive map that shows the location of fossil groups.
The site is a companion for the PBS TV series but it could also be used as a resource for teachers and students. The site is very well organized and provides clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum Web site. These hyperlinks make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over the current observational and experimental methods for analyzing evolutionary phenomena. In addition to studying the processes and events that happen regularly or over a lengthy period of time, paleobiology allows to examine the diversity of groups of organisms and their distribution in space over the course of geological time.
The site is divided into a variety of ways to learn about evolution that include "Evolution 101," which takes the user on a linear path through the scientific process and the evidence supporting the theory of evolution. The path also examines myths about evolution and the background of evolutionary thinking.
Each of the main sections on the Evolution website is equally well-designed, with materials that support a variety levels of curriculum and teaching methods. The site has a range of multimedia and interactive resources which include videos, animations, and virtual laboratories 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 vast web site.
For instance the page "Coral Reef Connections" provides an overview of coral relationships and their interaction with other organisms. It then narrows down to a single clam that is able to communicate with its neighbors and react to changes in water conditions that occur at the level of the reef. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a wide range of topics in evolutionary biology. The information also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis, which is a key method to understand evolutionary change.
Evolutionary Theory
Evolution is an underlying thread that runs through all branches of biology. A vast collection of books helps in teaching evolution across all disciplines of life sciences.
One resource, the companion to PBS's television series Understanding Evolution is an excellent example of an Web page that provides depth and breadth in terms of its educational resources. The site features a wealth of interactive learning modules. It also features 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 worlds of research science. Animation that introduces the concept of genetics links to a page that highlights John Endler's experiments with artificial selection using Guppies in native ponds in Trinidad.
에볼루션 슬롯 is the Evolution Library on this Web site, which has an extensive collection of multimedia resources connected to evolution. The content is organized into curricula-based pathways that correspond to the learning objectives set out in the standards for biology. It contains seven videos designed specifically for classroom use, which can be streamed for free or purchased on DVD.
Many important questions remain in the midst of evolutionary biology, such as the factors that trigger evolution and how fast it happens. This is especially true for human evolution, where it's been difficult to reconcile the idea that the physical characteristics of humans evolved from apes and religions that believe that humanity is unique among living things and has an exclusive place in the creation with a soul.
There are a variety of other ways evolution could occur, with natural selection as the most well-known theory. However, scientists also study other kinds of evolution like genetic drift, mutation, and sexual selection, among others.
While many scientific fields of inquiry have a conflict with literal interpretations of religious texts, evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, others aren't.
