Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, there are still a lot of misconceptions regarding evolution. People who have been exposed to popular science myths often assume that biologists are saying they do not believe in evolution.

This rich Web site - companion to the PBS series offers teachers with resources that support evolution education and 에볼루션 바카라 avoids the kinds of misinformation that can undermine it. It's laid out 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 have been guilty of using a definition that confuses the issue. This is particularly relevant to discussions about the definition of the word itself.

As such, it is essential to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site is both a companion for the 2001 series, but also a resource on its own. The content is presented in a nested fashion that assists in navigation and orientation.

The site defines terms like common ancestor, the gradual process and adaptation. These terms help to define the nature of evolution and its relation to other scientific concepts. The site also provides an overview of how the concept of evolution has been researched and confirmed. This information can help dispel myths that are created by the creationists.

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

The process of adaptation is the tendency of hereditary traits to become better suited to an environment. This is the result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less-adapted characteristics to survive and reproduce.

Common ancestor: The latest common ancestor of two or more distinct species. The common ancestor can be identified by analyzing the DNA of the species.

Deoxyribonucleic acid: A large biological molecule that contains the information required for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, referred to as chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or host and parasite.

Origins

Species (groups of individuals who can interbreed) change through a series of natural changes in the characteristics of their offspring. The changes can be triggered by a variety of causes that include natural selection, 에볼루션 무료 바카라 바카라 (Happy-magazine.Net) genetic drift, 에볼루션게이밍 and mixing of gene pools. The evolution of a new species could take thousands of years and the process can be slowed or increased by environmental conditions such as climate change or the competition for food or habitat.

The Evolution site tracks the development of a variety of groups of animals and plants over time with a focus on the key shifts that occurred throughout each group's history. It also examines the evolution of humans as a subject that is particularly important to students.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The famous skullcap, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was first published in 1858, which was a year following the initial edition of The Origin.

While the site focuses on biology, it contains a wealth of information about geology and paleontology. One of the most appealing features of the Web site are a timeline of events which show how geological and climatic conditions changed over time, as well as a map of the distribution of a few fossil groups listed on the site.

Although the site is a companion to a PBS television show, it also stands on its own as an excellent source for teachers and students. The site is well-organized and offers clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler’s experiments with guppies, which illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of plants, animals, and 에볼루션코리아 (this link) insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over modern observational and experimental methods of examining evolutionary phenomena. Paleobiology focuses on not only the process and events that take place regularly or over time, but also the relative abundance and distribution of different groups of animals in space throughout geological time.

The website is divided into a variety of paths to learning evolution that include "Evolution 101," which takes the user on a linear path through the nature of science and the evidence supporting the theory of evolution. The path also examines myths about evolution and the background of evolutionary thinking.

Each of the other major sections of the Evolution site is equally constructed, 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 array of interactive and multimedia resources like videos, animations and virtual laboratories. The breadcrumb-like arrangement of the content helps with navigation and orientation on the vast Web site.

For example, 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 the water conditions that occur at the level of the reef. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to a variety of topics in evolutionary biology. The content includes a discussion on the role of natural selectivity and the concept phylogenetics analysis as a key tool for understanding evolutionary changes.

Evolutionary Theory

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

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that provides the depth and the breadth in terms of its educational resources. The site has a variety of interactive learning modules. It also features a nested "bread crumb" structure that helps students move from the cartoon-like 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 is linked to a page that highlights John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.

Another resource that is worth mentioning is the Evolution Library on this Web website, which includes an extensive collection of multimedia assets connected to evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning objectives outlined in the standards for biology. It contains seven videos specifically designed for use in classrooms. These can be viewed online or purchased as DVDs.

Evolutionary biology is an area of study that poses many important questions to answer, such as the causes of evolution and how fast it happens. This is particularly applicable to human evolution where it's been difficult to reconcile the notion that the innate physical characteristics of humans evolved from apes, and the religions that believe that humans are unique among living things and holds a an enviable place in creation. It is a soul.

Additionally there are a variety of ways in which evolution could occur with natural selection being the most popular theory. However scientists also study other kinds of evolution, such as genetic drift, mutation, and sexual selection, among others.

Many fields of inquiry are in conflict with the literal interpretations of the Bible evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, other religions have not.
