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 aren't believers in evolution.

This rich Web site - companion to the PBS series offers teachers with resources that support evolution education and help avoid the kinds of misinformation that can hinder it. It's organized in a "bread crumb" format to make navigation and orientation easier.

Definitions

Evolution is a complex and challenging subject to teach effectively. It is often misunderstood even by non-scientists, and even scientists are guilty of using definitions that confuse the issue. This is particularly true when discussing the definition of the words.

Therefore, 에볼루션코리아 it is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, 에볼루션바카라 does this in a clear and helpful manner. The site is a companion site to the series that first aired in 2001, but it also functions 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, gradual process and adaptation. These terms help to define the nature of evolution as well as its relation to other concepts in science. The website then provides an overview of how the concept of evolution has been researched and validated. This information will help to dispel the myths that are created by the creationists.

You can also consult a glossary that contains terms used in evolutionary biology. These terms include:

Adaptation: The tendency for heritable traits to become better suited to a particular environment. This is a result of natural selection, which occurs when organisms with better-adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.

Common ancestor: 에볼루션 The most recent common ancestor of two or more species. The common ancestor can be identified through analyzing the DNA of those species.

Deoxyribonucleic acid: A large biological molecule that contains information necessary for cell replication. The information is stored in nucleotide sequences which are strung into long chains called chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey or the parasite and the host.

Origins

Species (groups of individuals who can interbreed) develop through natural changes in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The development of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food or habitat can impede or accelerate the process.

The Evolution site traces through time the emergence of various animal and plant groups with a focus on major changes within each group's past. It also examines the evolution of humans as a subject that is of particular interest for students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was one year before the first edition of the Origin was published, it is extremely unlikely that Darwin had heard or seen of it.

The site is primarily a biology site however it also includes lots of information about geology and paleontology. One of the most appealing features of the Web site are a series of timelines that illustrate the way in which climatic and geological conditions changed over time, as well as an outline of the geographical distribution of some fossil groups that are featured on the site.

The site is a companion for a PBS TV series but it can be used as a resource for teachers and students. The site is very well-organized and offers 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 Web site. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies. They illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced many species of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment is a superior method of study over modern observational or research methods for studying evolutionary phenomena. Paleobiology can examine not just the processes and events that occur regularly or over time but also the distribution and frequency of various animal groups across the geological time.

The Web site is divided into various pathways to understanding evolution which include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence that supports the theory of evolution. The path also examines myths about evolution as well as the history of evolutionary thinking.

Each of the other major sections of the Evolution site is similarly developed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. In addition to the general textual content, the site also has an extensive selection of multimedia and interactive content including videos, animations, and virtual laboratories. The content is presented in a nested bread crumb fashion that aids navigation and orientation within the vast web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and interactions with other organisms and then is enlarged to show one clam, which can communicate with its neighbors and react to changes in conditions of the water at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to the broad range of topics in evolutionary biology. The material includes an explanation of the importance of natural selection and the concept of phylogenetics which is a crucial method for understanding the evolution of changes.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach 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 offers both the depth and the breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also features an encased "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page that highlights John Endler's experiments in artificial selection with guppies in native ponds of Trinidad.

Another helpful resource is the Evolution Library on this web website, which includes an extensive library of multimedia items that are related to evolution. The content is organized in curricula-based paths that correspond to the learning objectives outlined in biology standards. It contains seven short videos intended for use in the classroom. They can be streamed or purchased as DVDs.

Evolutionary biology is still an area of study that has many important questions, including the causes of evolution and the speed at which it occurs. This is especially applicable to human evolution where it has been difficult to reconcile the notion that the innate physical characteristics of humans derived from apes and religions that believe that humanity is unique among living things and holds a a special place in creation with a soul.

There are a variety of other ways evolution could occur including natural selection, which is the most widely accepted theory. However, scientists also study other types of evolution such as mutation, genetic drift, 에볼루션 바카라 체험 룰렛 (39.98.88.1) and 에볼루션바카라 sexual selection, 에볼루션 슬롯게임 among others.

Although many scientific fields of study conflict with the literal interpretations of religious texts, evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, others haven't.
