How Evolution Site Influenced My Life For The Better
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 - companion to the PBS series It provides teachers with materials that promote evolution education and help avoid the kinds of misinformation that can hinder it. It's organized in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
Evolution is a complex and difficult subject to teach well. People who are not scientists often have a difficult time understanding the subject, and some scientists even use a definition which confuses it. This is particularly true when it comes to discussions on the definition of the word itself.
As such, it is 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 is a companion to the show that premiered in 2001, but it also functions as an independent resource. The material is presented in a nested manner that assists in navigation and orientation.
The site defines terms such as common ancestor (or common ancestor), gradual process and adaptation. These terms help define the nature of evolution and its relationship to evolution to other scientific concepts. The site also provides an overview of how the concept of evolution has been researched and confirmed. This information can be used to dispel the myths that have been propagated by the creationists.
It is also possible to access a glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency for 에볼루션 heritable characteristics to become more suitable to a particular setting. This is the result of natural selection, which occurs when organisms that have better-adapted traits are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified by studying the DNA of the species.
Deoxyribonucleic acid: A large biological molecule that contains information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, called chromosomes. Mutations are the basis for new genetic information in cells.
Coevolution is a relationship between two species where evolution of one species influence evolutionary changes of the other. Examples of coevolution are the interactions between predator and prey or parasite and host.
Origins
Species (groups that can interbreed), evolve by a series of natural variations in their offspring's traits. These changes are caused by a variety such as natural selection, genetic drift, and mixing of genes. The development of new species can take thousands of years. Environmental conditions, such as climate changes or competition for food resources and habitat can slow or speed up the process.
The Evolution site traces the emergence of various groups of animals and plants over time with a focus on the key shifts that occurred throughout the history of each group. It also focuses on human evolution, which is a topic of particular importance to students.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. One of them was the infamous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known 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 publication of the first edition of The Origin. Origin.
While the site focuses on biology, it also offers a lot of information about geology as well as paleontology. Among the best features on the site are a series of timelines that show how climatic and geological conditions have 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 for the PBS television series, but it could be used as a source for teachers and students. The site is well-organized and offers clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These hyperlinks help users move from the enthralling 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 that illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has led to a wide variety of animals, plants, and insects. Paleobiology, the study of these creatures in their geological context, has many advantages over modern observational or experimental methods for exploring evolutionary phenomena. Paleobiology is able to study not only processes and events that take place frequently or over time, but also the distribution and frequency of different groups of animals across geological time.
The site is divided into various pathways to understanding evolution that include "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence to support the theory of evolution. The path also examines myths regarding evolution, and also the history of evolutionary thinking.
Each of the other main sections of the Evolution site is equally developed, 에볼루션 바카라 사이트 with materials that can support a variety of educational levels and pedagogical styles. In addition to the general textual content, the site offers a wide range of multimedia and interactive content including video clips, animations, and virtual labs. The content is organized in a nested, bread crumb style that facilitates navigation and 무료에볼루션 orientation within the vast Web site.
The page "Coral Reef Connections", for example, gives a brief overview of the coral's relationships and their interactions with other organisms, and then zooms in to one clam that can communicate with its neighbors and respond to changes in the conditions of the water at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a wide variety 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 crucial tool for understanding the evolution of changes.
Evolutionary Theory
For biology students evolution is a crucial thread that connects all branches of the field. A wide selection of resources helps teachers teach evolution across the life science disciplines.
One resource, the companion to PBS's television series Understanding Evolution is an excellent example of an Web site that provides depth and wide range of educational resources. The site offers a range of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. An animation that introduces the concept of genetics links to a page that highlights John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.
The Evolution Library on this website is a vast multimedia library of resources that are associated to evolution. The content is organized according to curriculum-based paths that parallel the learning objectives set out in the standards for 바카라 에볼루션 biology. It contains seven videos specifically designed for use in classrooms. They are available to stream or purchase as DVDs.
A variety of crucial questions remain at the heart of evolutionary biology, including what causes evolution to occur and 에볼루션 바카라 체험코리아, clarke-morris-3.technetbloggers.de, the speed at which it occurs. This is particularly true for human evolution, where it has been difficult to reconcile the idea that the physical characteristics of humans evolved from apes, and the religions that believe that humanity is unique among living things and has an enviable place in creation. It is a soul.
In addition there are a myriad of ways that evolution could occur and natural selection is the most popular theory. However scientists also study different types of evolution such as genetic drift, mutation, and sexual selection, among others.
Many fields of inquiry have a conflict with the literal interpretations of religious texts evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the ideas of evolution, other religions aren't.
