Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. Pop science nonsense has led many people to believe that biologists don't believe evolution.

This rich Web site, which is a companion to the PBS program offers teachers resources that promote evolution education, while avoiding the kinds of misconceptions which make it difficult to understand. It's organized in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

It's difficult to effectively teach evolution. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. This is especially applicable to discussions on the meaning of the word itself.

It is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and 에볼루션 바카라 체험 helpful manner. The website is a companion to the show that premiered in 2001, but can also function as an independent resource. The content is organized in a manner that makes it simpler to navigate and understand.

The site defines terms such as common ancestor, gradual process, and adaptation. These terms help frame the nature and relationship of evolution to other concepts in science. The website provides a summary of the manner that evolution has been tested. This information can be used to dispel the myths that have been created by the creationists.

It is also possible to find a glossary of terms used in evolutionary biology. These terms include:

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

Common ancestor (also known as common ancestor) The most recent ancestral ancestor shared by two or 에볼루션 more species. By analyzing the DNA from these species, it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A huge biological molecular containing the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution include the interactions between predator and prey or host and parasite.

Origins

Species (groups which can interbreed) develop by a series of natural variations in their offspring's traits. The causes of these changes are many factors, such as 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 by environmental conditions such as climate change or the competition for food or habitat.

The Evolution site tracks through time the evolution of various animal and plant groups and focuses on major changes in each group's history. It also examines the evolution of humans, which is a topic of particular importance to students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, a year before the first edition of the Origin appeared, it is extremely unlikely that Darwin had heard or seen of it.

While the site focuses on biology, it includes a good deal of information about geology as well as paleontology. Among the best features of the website are a series of timelines which show the way in which climatic and geological conditions changed over time, and a map of the distribution of a few fossil groups that are featured on the site.

The site is a companion for the PBS TV series but it can be used as a resource for teachers and students. The site is extremely 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's web site. These links make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are also links to John Endler's experiments with guppies that illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life on Earth has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over the modern observational and research methods for analyzing evolutionary processes. Paleobiology focuses on not just the processes and events that happen regularly or over time, but also the distribution and frequency of various animal groups in space over the course of the geological time.

The site is divided up into several options to study the subject of evolution. One of the paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The path also explores the most common misconceptions about evolution, as well as the evolution of thought.

Each of the other major 에볼루션 사이트 sections of the Evolution site is equally constructed, with materials that support a variety of educational levels and pedagogical styles. The site has a range of interactive and multimedia content, including animations, video clips and virtual laboratories in addition to general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the massive website.

For example the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interaction with other organisms. Then, it zooms in on a single clam that can communicate with its neighbours and respond to changes in water conditions that take place at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to a variety of topics in evolutionary biology. The content also includes an explanation of the role of natural selectivity and the concept phylogenetics analysis as a key tool for understanding evolutionary change.

Evolutionary Theory

For biology students evolution is a crucial thread that binds all branches of the field. A wide range of resources can help teachers teach about evolution across the life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that offers both depth and breadth in its educational resources. The site has a variety of interactive learning modules. It also features a nested "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this huge site that are more closely tied to the world of research science. An animation that introduces the concept of genetics, which 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 contains a large multimedia library of materials that deal with evolution. The content is organized into curriculum-based paths that parallel the learning goals established in the standards for biology. It includes seven short videos designed specifically for use in the classroom, and can be streamed at no cost or purchased on DVD.

Evolutionary biology is an area of study that has many important questions, 에볼루션 게이밍 블랙잭 (Http://Www.Infinitymugenteam.Com:80/Infinity.Wiki/Mediawiki2/Index.Php/User:Evolution0581) such as what causes evolution and how fast it occurs. This is particularly true for human evolution, where it's been difficult to reconcile the idea that the physical characteristics of humans evolved from apes and religions that believe that humanity is unique among living things and has a special place in creation. It is a soul.

Additionally there are a myriad of ways in which evolution could be triggered with natural selection being the most popular theory. Scientists also study other types such as genetic drift, and sexual selection.

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