Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions regarding evolution. People who have been exposed to the nonsense of pop science often believe that biologists don't believe in evolution.

This site, a companion to the PBS program that provides teachers with resources which support evolution education, while avoiding the kinds of misconceptions that can undermine it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It's not easy to properly teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition that confuses it. This is particularly true when it comes to discussions on the definition of the word itself.

It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. It is an accompanying site for the 2001 series, but it is also a resource on its own. The content is presented in a structured way that makes it easy to navigate and understand.

The site defines terms such as common ancestor, gradual process, and adaptation. These terms help to define 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 examined. This information can help dispel the myths that are created by the creationists.

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

Adaptation: The tendency of heritable characteristics to become more adaptable to a specific environment. This is a result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adaptable characteristics to survive and reproduce.

Common ancestor: The most recent common ancestor of two or more species. By analyzing DNA from these species it is possible to identify the common ancestor.

Deoxyribonucleic acid: A massive biological molecule that holds the 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: A relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or parasites and hosts.

Origins

Species (groups which can interbreed), evolve through a series natural changes in their offspring's traits. The causes of these changes are numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of a new species can take thousands of years, and the process may be slowed or increased due to environmental conditions, such as climate change or competition for food or habitat.

The Evolution site traces through time the evolution of different groups of animals and plants with a focus on major changes within each group's past. It also examines the evolution of humans, which is a topic that is of particular interest to students.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans had been found. The famous skullcap, with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year before the first edition of the Origin was published, it is extremely unlikely that Darwin had seen or heard of it.

The site is primarily a biology site however it also includes many details on paleontology and geology. One of the most appealing features of the website are a timeline of events that show how geological and climatic conditions have changed over time and an outline of the geographical distribution of some fossil groups that are featured on the site.

The site is a companion for the PBS television series, 무료 에볼루션 but it can be used as a resource by teachers and students. The site is extremely well organized and provides clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These hyperlinks help users move from the engaging 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 demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology is the study of these creatures in their natural environment and has numerous advantages over modern observational and experimental methods in its exploration of evolutionary phenomena. In addition to examining processes and events that take place regularly or over a lengthy period of time, paleobiology can be used to study the relative abundance of different kinds of organisms as well as their distribution in space over the course of geological time.

The site is divided into various ways to learn about evolution, including "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence supporting the theory of evolution. The path also reveals common misconceptions about evolution and 에볼루션 게이밍 the evolution of thought.

Each of the other sections of the Evolution site is equally constructed, with materials that can support a variety of curriculum levels and pedagogical styles. The site has a range of interactive and 에볼루션 카지노 multimedia resources which include animations, video clips and virtual labs as well as general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the vast web site.

For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms. It then concentrates on a specific clam that can communicate with its neighbours and respond to changes in water conditions that occur at the reef level. This page, 에볼루션카지노사이트 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 an overview of the importance of natural selection as well as the concept of phylogenetic analysis, which is an important tool in understanding evolutionary change.

Evolutionary Theory

For biology students, evolution is a key thread that weaves together all the branches of the field. A wide range of resources helps teachers teach about evolution across all life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that offers both the depth and breadth of its educational resources. The site features a wealth of interactive learning modules. It also has an "bread crumb structure" that assists students in moving away from the cartoon style that is used in Understanding Evolution and onto elements on this site that are more closely connected to the fields of research science. An animation that introduces the concept of genetics, which links to a page that highlights John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad.

Another resource that is worth mentioning is the Evolution Library on this web website, which includes an extensive collection of multimedia items related to evolution. The content is organized into curriculum-based pathways that correspond to the learning goals set forth in the standards for biology. It includes seven short videos specifically designed for classroom use. These can be viewed online or purchased as DVDs.

Many important questions remain at the heart of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is particularly true for human evolution, where it has been difficult to reconcile the notion that the innate physical characteristics of humans evolved from apes with religious beliefs that hold that humanity is unique among living things and holds a an exclusive place in the creation, with soul.

There are a variety of other ways evolution could occur including natural selection, which is the most widely accepted theory. Scientists also study other types such as genetic drift and sexual selection.

Although many scientific fields of study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been a source of intense controversy and opposition from religious fundamentalists. Certain religions have embraced their beliefs to evolution but others haven't.
