Evolution Site - Teaching About Evolution

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

This rich website - companion to the PBS series It provides teachers with materials that promote evolution education and avoid the kinds of misinformation that can make it difficult to understand. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and challenging subject to teach effectively. It is often misunderstood by non-scientists and even scientists are guilty of using an interpretation that is confusing the issue. This is especially true when it comes to discussions about the meaning of the word itself.

It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and 에볼루션게이밍 useful way. The website is a companion to the series that first aired in 2001, but it can also function as an independent resource. The material is presented in a nested fashion that aids navigation and orientation.

The site defines terms such as common ancestor, gradual process and so on. These terms help to frame the nature of evolution as well as its relation to other scientific concepts. The site gives a comprehensive overview of the ways that evolution has been examined. This information can be used to dispel misconceptions that have been created by the creationists.

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

Adaptation is the tendency of hereditary traits to become more suitable to their environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted traits to reproduce and survive.

Common ancestor: The latest common ancestor of two or more distinct species. By analyzing 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 sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution: A relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be seen in the interaction of predator and prey, or parasite and 무료 에볼루션 hosts.

Origins

Species (groups that can crossbreed), evolve through a series natural changes in the traits of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, like climate changes or competition for food and habitat, can slow or accelerate the process.

The Evolution site tracks through time the emergence of various species of plants and animals and focuses on major changes in each group's history. It also examines the evolution of humans, which is a topic that is of particular interest for students.

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

While the site focuses on biology, it includes a good deal of information on geology and paleontology. One of the most appealing features on the site are a timeline of events that show how climatic and 에볼루션 사이트 geological conditions have changed over time and an outline of the distribution of some of the fossil groups featured on the site.

The site is a companion for the PBS TV series but it can also be used as a source for teachers and students. The site is well-organized, and provides easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features of the museum's website. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also 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 resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment is a superior method of study over modern observational or experimental methods for studying evolutionary phenomena. Paleobiology is able to study not only the process and events that happen regularly or 에볼루션 슬롯게임 over time but also the distribution and frequency of different species of animals in space throughout the geological time.

The site is divided up into different routes that can be taken to gain knowledge about evolution. One of these paths, "Evolution 101," takes the viewer through the nature and evidence of evolution. The path also explores misconceptions about evolution, as well as the history of evolutionary thinking.

Each of the other sections of the Evolution site is equally constructed, 에볼루션 with materials that can be used to support a range of educational levels and pedagogical styles. The site includes a variety of multimedia and interactive resources that include animations, video clips and virtual laboratories as well as general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the massive web site.

For example, the page "Coral Reef Connections" provides an overview of coral relationships and 에볼루션 사이트 their interaction with other organisms, then narrows down to a single clam that is able to communicate with its neighbors and respond to changes in water conditions that take place at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, gives a good introduction to a variety of topics in evolutionary biology. The material includes a discussion on the importance of natural selection and the concept of phylogenetics analysis, an important method for 에볼루션 게이밍 understanding the evolution of change.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A rich collection supports teaching evolution across the disciplines of life science.

One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both depth and a variety of educational resources. The site features a wealth of interactive learning modules. It also features an encased "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this massive website that are more closely linked to the world of research science. Animation that introduces the concept of genetics, which links to a page about John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.

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

A variety of crucial questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it happens. This is especially applicable to human evolution where it's been difficult to reconcile the notion that the physical traits of humans evolved from apes, and the religious beliefs that claim that humans are unique in the universe and has an enviable place in creation with a soul.

There are a variety of other ways in which evolution can take place and natural selection being the most well-known theory. However scientists also study other types of evolution such as mutation, genetic drift and sexual selection, among others.

Many fields of inquiry are in conflict with literal interpretations of religious texts, evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions aren't.
