5 Evolution Site Projects For Any Budget

Evolution Site - Teaching About Evolution

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

This rich website - companion to the PBS series It provides teachers with materials that support evolution education and avoids the kinds of misinformation that can make it difficult to understand. It's laid out in the "bread crumb" format to aid in navigation and orientation.

Definitions

It's not easy to effectively teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition that confuses it. This is especially relevant when discussing the meaning of the words themselves.

It is crucial to define the terms used in evolutionary biology. Understanding Evolution's website provides this in an easy and 에볼루션 바카라 체험카지노사이트; Www.meetme.com, helpful manner. The website is a companion to the series that first aired in 2001, but it also functions as an independent resource. The content is presented in a nested manner which aids navigation and orientation.

The site defines terms such as common ancestor, gradual process and so on. These terms help frame 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 tested and verified. This information can be used to dispel the myths that have been engendered by the creationists.

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

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

Common ancestor: The most recent common ancestor of two or more species. By analyzing the DNA from these species it is possible to identify the common ancestor.

Deoxyribonucleic acid: A large biological molecule that contains the information required for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, called chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is a relationship between two species where evolution of one species influence evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or host and parasite.

Origins

Species (groups of individuals that are able to interbreed) change through an array of natural changes in the characteristics of their offspring. Changes can be caused by various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental circumstances, such as climate changes or competition for food and habitat can impede or accelerate the process.

The Evolution site follows the emergence of various groups of animals and plants and focuses on major changes in each group's past. It also examines the human evolutionary roots, a topic that is particularly important for students to understand.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. One of them was the infamous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, a year before the first edition of the Origin was published, it is extremely unlikely that Darwin had seen or heard of it.

The site is mostly one of biology however it also includes lots of information about paleontology and geology. The most impressive features of the website are a series of timelines that show how climatic and geological conditions have changed over time, and an outline of the geographical distribution of some fossil groups listed on the site.

While the site is a companion to the PBS television series but it also stands on its own as a great resource for teachers and students. The site is well-organized and offers easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features on the museum's website. These hyperlinks facilitate the move from the enthralling 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 has resulted in an array of animals, plants and insects. Paleobiology is the study of these creatures within their geographical context and offers a number of advantages over the modern observational and 에볼루션 무료체험 research methods of examining evolutionary processes. In addition to studying the processes and events that happen regularly or over a long period of time, paleobiology can be used to examine the diversity of groups of organisms and their distribution throughout the geological time.

The site is divided into several optional paths to learning evolution, including "Evolution 101," which takes the viewer on a line through the science of nature and the evidence that supports the theory of evolution. The path also examines myths about evolution, and the background of evolutionary thinking.

Each of the main sections of the Evolution website is equally well-designed, with materials that can be used to support a variety of levels of curriculum and teaching methods. In addition to the standard textual content, the site features a wide range of interactive and multimedia resources like videos, animations and virtual laboratories. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the vast Web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships, their interaction with other organisms and is enlarged to show one clam that can communicate with its neighbors and respond to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to many topics in evolutionary biology. The content also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis, 에볼루션 which is an important tool for understanding the evolution of changes.

Evolutionary Theory

For biology students evolution is a crucial thread that connects all the branches of the field. A wide range of resources supports teaching about evolution across the life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and breadth in its educational resources. The site offers 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, which links to a page that highlights John Endler's experiments with artificial selection using Guppies in native ponds in Trinidad.

Another helpful resource is the Evolution Library on this web site, which contains an extensive collection of multimedia items related to evolution. The content is organized according to curriculum-based paths that parallel the learning objectives set out in the biology standards. It contains seven videos specifically designed for classroom use, which can be streamed for no cost or purchased on DVD.

Many important questions remain in the midst of evolutionary biology, including what causes evolution to occur and how fast it occurs. This is especially true for humans' evolution where it was a challenge to reconcile religious beliefs that held that humans have a distinct position in the universe and a soul, with the idea that innate physical traits evolved from the apes.

There are also a number of other ways evolution can take place including natural selection, which is the most widely accepted theory. Scientists also study different types such as mutation, genetic drift and sexual selection.

While many fields of scientific inquiry conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
