How To Choose The Right Evolution Site On The Internet

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. People who have absorbed the nonsense of pop science often believe that biologists are saying they do not believe in evolution.

This rich Web site, a companion to the PBS program, provides teachers with materials that support the evolution of education while avoiding the types of misconceptions which make it difficult to understand. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complicated and difficult subject matter to teach effectively. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is especially relevant when it comes to the nature of the words themselves.

It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site serves as a companion for the 2001 series, but it is also a resource on its own. The content is presented in an organized manner that makes it easier to navigate and understand.

The site defines terms such as 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 provides an overview of the ways the concept of evolution has been tested. This information can be used to dispel myths that have been created by creationists.

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

Adaptation is the process of changing 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 species. By analyzing DNA from these species, it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular containing the information required for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be observed through the interaction between predator and prey, or parasites and hosts.

Origins

Species (groups that can crossbreed), evolve through a series natural changes in the traits of their offspring. These changes are caused by a variety of factors, including natural selection, genetic drift and mixing of gene pools. 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 the competition for 에볼루션 무료 바카라 food or habitat.

The Evolution site follows the emergence of various animal and plant groups and focuses on major changes in each group's past. It also explores human evolution and 무료 에볼루션 룰렛 (navigate to this web-site) is a subject of particular importance for students.

Darwin's Origin was published in 1859, when only a handful of antediluvian fossils of humans had been found. One of them was the infamous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany, 에볼루션 룰렛 which is now known to be an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, which was a year after the publication of the first edition of The Origin.

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

The site is a companion for the PBS television series, but it can also be used as an educational resource for teachers and students. The site is extremely well-organized and has clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These hyperlinks make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are hyperlinks to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of animals, plants, and insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over the current observational and experimental methods in its exploration of evolutionary processes. In addition to studying the processes and events that happen regularly or over a lengthy period of time, paleobiology can be used to analyze the relative abundance of various species of organisms and their distribution across geological time.

The website is divided into various routes that can be taken to learn about evolution. One of these paths, "Evolution 101," guides the user through the evolution of nature and the evidence of evolution. The path also reveals the most common misconceptions about evolution, as well as the evolution of thought.

Each of the other sections of the Evolution site is similarly created, with resources that can support a variety of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia content that include video clips, animations and virtual labs as well as general textual content. The breadcrumb-like organization of the content aids in navigation and orientation on the massive Web site.

The page "Coral Reef Connections", for example, provides a comprehensive overview of the relationships between corals and interactions with other organisms and then zooms in on a single clam, which is able communicate with its neighbors and react to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a wide range of topics in evolutionary biology. The material includes an explanation of the significance of natural selectivity and 에볼루션 무료 바카라 the concept of phylogenetics, an important tool to understand evolutionary changes.

Evolutionary Theory

For biology students the concept of evolution is a major thread that connects all the branches of the field. A vast 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 offers both the depth and breadth of its educational resources. The site offers a range of interactive learning modules. It also has an encased "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. An animation that introduces the concept of genetics is linked to a page about John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.

Another useful resource is the Evolution Library on this website, which includes an extensive multimedia library of resources connected to evolution. The content is organized into curricula-based paths that correspond to the learning objectives set out in the standards for biology. It includes seven short videos designed specifically for classroom use, which can be streamed for free or purchased on DVD.

Evolutionary biology is still an area of study with a lot of important questions to answer, such as the causes of evolution and how fast it happens. This is particularly relevant for humans' evolution where it was a challenge to reconcile religious beliefs that held that humanity has a special position in the universe and a soul with the idea that innate physical traits evolved from apes.

In addition, there are a number of ways that evolution can occur with natural selection being the most widely accepted theory. Scientists also study other kinds such as genetic drift and sexual selection.

While many scientific fields of inquiry have a conflict with the literal interpretations of the Bible Evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs to evolution while others haven't.
