Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.

This site, which is a companion to the PBS series - provides teachers with materials that support evolution education and help avoid the kinds of misinformation that can undermine it. It's laid out in the "bread crumb" format to make navigation and orientation easier.

Definitions

It's not easy to teach evolution well. It is often misunderstood even by non-scientists, and even some scientists use a definition that confuses the issue. This is particularly true when it comes to discussions on the nature of the word.

It is important to define terms used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient manner. It is an accompaniment to the 2001 series, but it is also a resource on its own. The material is presented in a nested fashion that assists in navigation and orientation.

The site defines terms like common ancestor and gradual process. These terms help frame the nature of evolution and 에볼루션 바카라 무료 its relationship to evolution to other concepts in science. The website provides a summary of the way in which evolution has been tested. This information can help dispel 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 hereditary traits to become more suited to a particular environment. This is a result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adapted traits to reproduce and 에볼루션 바카라 survive.

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

Deoxyribonucleic Acid: A massive biological molecular that contains the information required for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

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

Origins

Species (groups of individuals who can interbreed) develop through a series of natural changes in the traits of their offspring. Changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The development 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 competition for food or habitat.

The Evolution site follows the evolution of various species of plants and animals with a focus on major changes within each group's past. It also explores human evolution as a subject of particular importance to students.

Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans were discovered. One of them was the infamous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was published in 1858, one year after the first edition of The Origin.

While the site focuses on biology, it includes a good deal of information about geology and paleontology. The Web site has a number of features that are especially impressive, including a timeline of how climate and geological conditions have changed over time. It also features maps that show the locations of fossil groups.

The site is a companion for 에볼루션 바카라 무료 the PBS television series, but it could be used as a resource for teachers and students. The site is well-organized, and provides clear links to the introductory content of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features of the museum website. These hyperlinks help users move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly 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 resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures within their geological environment, has many advantages over modern observational or experimental methods of studying evolutionary processes. In addition to examining the processes and events that happen frequently or over a long period of time, paleobiology allows to examine the relative abundance of various kinds of organisms as well as their distribution throughout geological time.

The site is divided into different routes that can be taken to study the subject of evolution. One of these paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also explores misconceptions about evolution and also the history of evolutionary thought.

Each of the main sections on the Evolution website is equally well-developed, 에볼루션 블랙잭 and includes materials that support a variety levels of curriculum and teaching methods. The site offers a wide array of interactive and multimedia content that include animations, video clips and virtual labs, in addition to its general textual content. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the large Web site.

For example the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms, then narrows down to a single clam that can communicate with its neighbours and respond to changes in the water conditions that occur at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, offers a great introduction to the many areas of evolutionary biology. The content includes an explanation of the importance of natural selection and the concept of phylogenetics as a key tool to understand evolutionary change.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A rich collection of resources supports teaching about evolution across all life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides depth and a variety of educational resources. The site features a wide range of interactive learning modules. It also has an "bread crumb structure" that helps students move away from the cartoon style of Understanding Evolution and onto elements on this large website more closely related to the fields of research science. For example an animation that introduces the concept of genetic inheritance links to a page that highlights John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives set out in biology standards. It contains seven short videos intended for use in the classroom. They can be viewed online or purchased as DVDs.

Evolutionary biology remains an area of study that has many important questions to answer, such as what triggers evolution and how quickly it occurs. This is particularly true for the evolution of humans where it was a challenge to reconcile religious beliefs that held that humans have a distinct position in the universe and 에볼루션 바카라 무료 a soul, with the idea that innate physical traits originated from the apes.

In addition there are a myriad of ways in which evolution could be triggered and natural selection is the most widely accepted theory. Scientists also study other types such as mutation, genetic drift, and sexual selection.

While many scientific fields of study conflict with literal interpretations found in religious texts, evolution biology has been a source of intense debate and resistance from religious fundamentalists. Certain religions have embraced their beliefs to evolution while others haven't.
