Comprehensive Guide To Evolution Site
Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, there are still a lot of misconceptions regarding evolution. People who have taken in pop science nonsense often assume that biologists claim they do not believe in evolution.
This rich Web site - companion to the PBS series - provides teachers with materials that promote evolution education and help avoid the kinds of misinformation that can undermine it. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complex and difficult subject to teach well. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is especially true when discussing the nature of the words themselves.
As such, it is important to define terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful manner. The site is a companion site to the show that premiered in 2001, but it also functions as an independent resource. The content is presented in an organized manner that makes it easier to navigate and comprehend.
The site defines terms like common ancestor, gradual process, and adaptation. These terms help to frame the nature of evolution and its relationship to other concepts in science. The site gives a comprehensive overview of the ways that evolution has been tested. This information can be used to dispel misconceptions that have been created by creationists.
You can also access a glossary which includes terms used in evolutionary biology. These terms include:
Adaptation is the tendency of heritable traits to be more suitable to their environment. This is a result of natural selection. Organisms with more adaptable traits are more likely than those with less-adapted traits to survive and reproduce.
Common ancestor: The most recent common ancestor of 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 needed for cell replication. The information is stored in nucleotide sequences, which are strung into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.
Coevolution: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution is evident in the interaction of predator and prey, or parasites and hosts.
Origins
Species (groups that can interbreed) change through a series of natural changes in the traits of their offspring. The changes can be triggered by a variety of factors, including natural selection, genetic drift, and gene pool mixing. The evolution of new species could take thousands of years. Environmental conditions, such as climate changes or competition for food and habitat can slow or speed up the process.
The Evolution site traces the emergence of a number of different animal and plant groups through time, focusing on the major shifts that occurred throughout the history of each group. It also focuses on the human evolutionary roots, a topic that is especially important for students to comprehend.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap when it was published in 1858, one year after the first edition of The Origin. Origin.
The site is primarily an online biology resource, but it also contains many details on geology and paleontology. The site offers a number of features that are especially impressive, including a timeline of how geological and climate conditions have changed over time. It also features maps that show the locations of fossil groups.
The site is a companion to a 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 information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These hyperlinks help users move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology, the study of these creatures within their natural environment, has many advantages over modern observational or experimental methods for studying evolutionary phenomena. In addition to studying processes and events that take place frequently or 에볼루션바카라사이트 over a long period of time, paleobiology can be used to study the relative abundance of different species of organisms and their distribution in space over the geological time.
The Web site is divided into various pathways to understanding evolution, including "Evolution 101," which takes the viewer on a line through the science of nature and the evidence that supports the theory of evolution. The path also examines myths about evolution, and also the history of evolutionary thought.
Each of the other major sections of the Evolution site is equally well developed, with materials that can be used to support a range of curriculum levels and pedagogical styles. In addition to the standard textual content, the site also has an extensive selection of interactive and multimedia resources including videos, animations, and virtual labs. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation within the vast web site.
The page "Coral Reef Connections", for example, provides a comprehensive overview of the relationships between corals and their interactions with other organisms and zooms in to one clam that can communicate with its neighbors and respond to changes in the water conditions that occur on the reef level. This page, 에볼루션바카라 as well as the other multidisciplinary, multimedia and interactive pages on the website, 바카라 에볼루션카지노 - Read the Full Posting, provide an excellent introduction to the broad range of topics in evolutionary biology. The content also includes a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a crucial tool for understanding the evolution of changes.
Evolutionary Theory
Evolution is an underlying thread that is found throughout all branches of biology. A wide range of resources supports teaching about evolution across the life sciences.
One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that provides depth and breadth in terms of its educational resources. The site offers a variety of interactive learning modules. It also has a "bread crumb structure" that allows students to move away from the cartoon-like style that is used in Understanding Evolution and onto elements on this large website more closely linked to the worlds of research science. For example an animation that explains the concept of genetic inheritance links to a page that highlights John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.
Another helpful resource is the Evolution Library on this Web site, 에볼루션 바카라 무료 which contains an extensive collection of multimedia assets connected to evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives set out in the standards for biology. It contains seven short videos designed for use in classrooms. These can be streamed or purchased as DVDs.
Evolutionary biology is still an area of study with a lot of important questions, such as what triggers evolution and how fast it occurs. This is particularly applicable to human evolution where it's been difficult to reconcile the idea that the innate physical characteristics of humans were derived from apes with religious beliefs that claim that humans are unique in the universe and has an enviable place in creation. It is a soul.
Additionally there are a variety of ways in which evolution could be triggered with natural selection being the most popular theory. Scientists also study different types such as mutation, genetic drift and sexual selection.
While many fields of scientific study conflict with the literal interpretations of religious texts, the concept of evolution biology has been a subject of intense debate and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, while others haven't.
