Why Evolution Site Could Be More Dangerous Than You Realized

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. People who have absorbed popular science myths often assume that biologists don't believe in evolution.

This site, which is a complement to the PBS program that provides teachers with resources which support evolution education, while avoiding the kinds of misconceptions which make it difficult to understand. It's organized in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to properly teach evolution. Many non-scientists are unable to grasp the concept and some scientists employ a definition that confuses it. This is particularly relevant when discussing the definition of the words.

It is therefore important 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 is both a companion for the 2001 series, but also a resource on its own. The content is presented in a nested manner that aids navigation and orientation.

The site defines terms like common ancestor and gradual process. These terms help to define the nature of evolution and its relation to other scientific concepts. The website provides a summary of the ways in which evolution has been tested. This information can be used to dispel misconceptions that have been propagated by creationists.

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

Adaptation is the tendency of heritable traits to become more suited to the environment. This is the result of natural selection, which occurs when organisms that are better adapted characteristics are more likely to survive and reproduce than those with less adapted traits.

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

Deoxyribonucleic acid: A huge biological molecule that holds the information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form long chains, called chromosomes. Mutations are the cause of new genetic information within cells.

Coevolution is a relation between two species in which the evolution of one species are influenced by evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups of individuals that are able to interbreed) evolve through a series of natural changes in the characteristics of their offspring. These changes are caused by a variety of causes such as natural selection, genetic drift and mixing of genes. The development of a new species could take thousands of years, and the process can be slowed or increased by environmental factors like climate change or the competition for food or habitat.

Darwin's Origin was published in 1859, when just a handful of antediluvian fossils of humans had been found. The famous skullcap, along with the associated bones, 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 knew about the skullcap when it was published in 1858, which was a year following the initial edition of The Origin. Origin.

The site is mostly one of biology however, it also has a lot of information on paleontology and geology. The site offers numerous aspects that are quite impressive, including the timeline of the way that climate and geological conditions have changed over time. It also includes maps that show the locations of fossil groups.

Although the site is a companion to a PBS television series however, it can stand on its own as an excellent source for teachers and students. The site is extremely well organized and provides 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's web site. These links facilitate the transition from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world 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 has produced an array of plants, animals and insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over the modern observational and research methods of examining evolutionary processes. In addition to studying processes and events that occur regularly or over a long period of time, paleobiology is able to examine the relative abundance of various kinds of organisms as well as their distribution across geological time.

The site is divided up into several paths that can be chosen to gain knowledge about evolution. One of the paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The path also explores misconceptions regarding evolution, as well as the history of evolutionary thinking.

Each of the other major sections of the Evolution site is similarly created, with resources that support a variety of curriculum levels and pedagogical styles. In addition to general textual content, the site features a wide range of interactive and multimedia resources, such as videos, animations and virtual laboratories. The content is organized in a nested, bread crumb style that facilitates navigation and orientation on the web site.

This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to many topics in evolutionary biology. The content includes a discussion on the significance of natural selectivity and the concept phylogenetics analysis as a key tool to understand evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A vast collection of resources supports teaching about evolution across the life sciences.

One resource, the companion to PBS's television series Understanding Evolution is an excellent example of an Web site that provides depth and wide range of educational resources. The site features a wealth of interactive learning modules. It also has a "bread crumb structure" that helps students move away from the cartoon-like style used in Understanding Evolution and onto elements on this site that are more closely connected to the fields of research science. Animation that introduces the concept of genetics is linked to a page highlighting John Endler's experiments with artificial selection using Guppies in native ponds in Trinidad.

Another resource that is worth mentioning is the Evolution Library on this web website, which includes an extensive library of multimedia assets connected to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives set out in the biology standards. It contains seven short videos intended for use in the classroom. These are available to stream or purchase as DVDs.

A variety of crucial questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is especially relevant to human evolution, which has made it difficult to reconcile that the innate physical characteristics of humans derived from apes with religious beliefs that claim that humanity is unique among living things and holds a a special place in creation, with a soul.

There are a myriad of other ways in which evolution can take place, with natural selection as the most popular theory. However scientists also study different types of evolution such as mutation, genetic drift, and sexual selection, among other things.

While many fields of scientific inquiry conflict with literal interpretations of religious texts evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, but others haven't.
