10 Healthy Evolution Site Habits
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution persist. Pop science nonsense has led many people to believe that biologists don't believe evolution.
This rich Web site, a companion to the PBS program, provides teachers with materials that support the evolution of education, while avoiding the kinds of misconceptions that can hinder it. It's organized in a "bread crumb" format to make navigation and orientation easier.
Definitions
Evolution is a complicated and difficult subject matter to teach effectively. It is often misunderstood by non-scientists and even some scientists have been guilty of using a definition that confuses the issue. This is particularly relevant when it comes to the definition of the words.
It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site serves as a companion for the 2001 series, and also a resource on its own. The material is presented in a nested fashion that assists in navigation and orientation.
The site defines terms like common ancestor, gradual process and so on. These terms help to define the nature of evolution and its relationship to evolution to other scientific concepts. The website provides a summary of the ways the concept of evolution has been examined. This information can help dispel the myths that are created by the creationists.
It is also possible to access the glossary of terms used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to become more suited to the environment. This is the result of natural selection, which happens when organisms with better adapted traits are more likely to survive and reproduce than those with less adaptable traits.
Common ancestor: The most recent common ancestor of two or more species. The common ancestor can be identified by studying the DNA of these species.
Deoxyribonucleic acid: A large biological molecule that contains information necessary for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, called chromosomes. Mutations are the source of new genetic information in cells.
Coevolution is a relation between two species in which the evolutionary changes of one species are influenced evolutionary changes of the other. Coevolution is evident in the interaction of predator and prey, or parasites and hosts.
Origins
Species (groups of individuals that are able to interbreed) develop through an array of natural changes in the traits of their offspring. The changes can be caused by a variety that include natural selection, genetic drift, and gene pool mixing. The evolution of a new species can take thousands of years and the process may be slowed down or speeded up by environmental factors like climate change or the competition for food or habitat.
The Evolution site traces through time the evolution of various animal and plant groups and focuses on major changes within each group's past. It also focuses on the evolutionary history of humans and humans, a subject that is particularly important for students to comprehend.
Darwin's Origin was published in 1859, when only a handful of 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 that is now thought to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was a year before the first edition of the Origin appeared, it is highly unlikely that Darwin had seen or heard of it.
While the site focuses on biology, it also contains a wealth of information about geology and paleontology. One of the most appealing features on the site are a set of timelines that show how climatic and geological conditions changed over time, as well as an outline of the distribution of some fossil groups that are featured on the site.
The site is a companion to a PBS TV series but it could be used as a resource for 에볼루션게이밍 (Read More In this article) teachers and students. The site is well-organized and 에볼루션 무료 바카라 블랙잭 (you could look here) offers easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features of the museum website. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler's experiments with guppies. They demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology, the study of these creatures within their natural environment, has many advantages over the current observational or experimental methods for studying evolutionary phenomena. In addition to exploring processes and events that take place regularly or over a long period of time, paleobiology can be used to examine the relative abundance of various species of organisms and their distribution throughout geological time.
The site is divided into a variety of pathways to understanding evolution, including "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 misconceptions about evolution as well as the history of evolutionary 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 curriculum levels and teaching styles. In addition to the general textual content, the site offers an array of multimedia and interactive content, such as video clips, animations, and virtual labs. The breadcrumb-like structure of the content assists with navigation and orientation on the large Web site.
For example the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms. It then concentrates on a specific clam that is able to communicate with its neighbors and react to changes in water conditions that take place at the level of the reef. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great introduction to many topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is an important tool for understanding the evolution of change.
Evolutionary Theory
Evolution is a common thread that runs through all branches of biology. A vast collection of books helps in teaching evolution across all disciplines of life science.
One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth and wide range of educational resources. The site has a wide array of interactive learning modules. It also has an "bread crumb structure" that allows students to move away from the cartoon style used in Understanding Evolution and onto elements of this vast website that are closely related to the worlds of research science. For instance an animation that introduces the idea of genetic inheritance connects to a page that highlights John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad.
The Evolution Library on this website contains a large multimedia library of assets related to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning goals set forth in the standards for biology. It contains seven videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD.
Many important questions remain in the midst of evolutionary biology, including the factors that trigger evolution and how fast it happens. This is particularly applicable to human evolution where it has been difficult to reconcile the idea that the physical traits of humans evolved from apes and religions that believe that humanity is unique in the universe and has an enviable place in creation with soul.
There are a myriad of other ways in which evolution could occur and 에볼루션카지노사이트 natural selection being the most popular theory. Scientists also study other types such as mutation, genetic drift and sexual selection.
While many scientific fields of study conflict with literal interpretations in religious texts, 에볼루션 바카라 evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
