Are Evolution Site Just As Important As Everyone Says?

Evolution Site - Teaching About Evolution

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

This site, a companion to the PBS program, provides teachers with materials that promote evolution education while avoiding the types of misconceptions which hinder it. It's organized in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to teach evolution well. It is often misunderstood even by non-scientists, and even some scientists are guilty of using an interpretation that is confusing the issue. This is especially true when it comes to discussions about the definition of the word itself.

As such, it is essential to define 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 an accompaniment to the 2001 series, and also a resource on its own. The material is organized in a way that makes it easy to navigate and understand.

The site defines terms such as common ancestor, the gradual process, and adaptation. These terms help to define the nature and relationship of evolution to other concepts in science. The site provides an overview of the way the concept of evolution has been tested. This information can be used to dispel misconceptions that have been engendered by creationists.

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

Adaptation is the process of changing heritable traits to be better suited to an environment. This is a result of natural selection, which happens when organisms that have more adaptable traits are more likely to survive and reproduce than those with less adaptable characteristics.

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

Deoxyribonucleic Acid: A massive biological molecular that holds the necessary information 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 within cells.

Coevolution is a relation between two species in which the evolutionary changes of one species are influenced evolutionary changes of the other. Coevolution is evident in the interaction of predator and prey, or parasite and hosts.

Origins

Species (groups that can crossbreed), evolve through a series of natural changes in their offspring's traits. Changes can be caused by numerous factors, like natural selection, gene drift and mixing of the gene pool. The development of a new species may take thousands of years, and the process could be slowed down or speeded up by environmental factors like climate change or the competition for food or habitat.

Darwin's Origin was written in 1859, when only a few antediluvian fossils of humans had been found. The famous skullcap, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was published in 1858, one year after the first edition of The Origin. Origin.

The site is primarily an online biology resource, but it also contains a lot of information on geology and paleontology. The website has numerous features that are particularly impressive, including the timeline of how geological and climate conditions have changed over the course of time. It also features an interactive map that shows the location of fossil groups.

Although the site is a companion to the PBS television series however, it can stand on its own as a great source for teachers and students. The site is well-organized and has clear links between the introductory material 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 research with Guppies, which 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 geographical context and offers many advantages over the modern observational and research methods for analyzing evolutionary phenomena. In addition to studying the processes and events that happen frequently or over a long period of time, paleobiology allows to study the relative abundance of different species of organisms and their distribution across the course of 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 scientific process and the evidence supporting the theory of evolution. The path also explores misconceptions about evolution and also the history of evolutionary thinking.

Each of the other sections of the Evolution site is equally well created, with resources that can support a variety of curriculum levels and pedagogical styles. In addition to the standard textual content, the site offers an array of multimedia and interactive content, such as video clips, animations, and virtual laboratories. The content is laid out in a nested bread crumb style that facilitates 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 the coral's relationships, their interaction with other organisms and zooms in to one clam, which is able communicate with its neighbours and respond to changes in conditions of the water at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to the broad spectrum of topics in evolutionary biology. The material also provides an overview of the importance of natural selection and the concept of phylogenetic analysis which is a key method to understand evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A wide range of resources helps teachers teach about evolution across all life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that provides depth and a variety of educational resources. The site offers a variety of interactive learning modules. It also features an "bread crumb structure" that assists students in moving away from the cartoon-like style that is used in Understanding Evolution and onto elements on this large website more closely linked to the worlds of research science. For example, an animation introducing the concept of genetic inheritance links to a page highlighting John Endler's experiments in artificial selection 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 into curricula-based paths that correspond to the learning goals set forth in biology standards. It contains seven videos specifically designed for use in the classroom, and can be streamed for free or purchased on DVD.

A variety of crucial questions remain at the core of evolutionary biology, including what causes evolution to occur and how fast it happens. This is especially true for humans' evolution where it was a challenge to reconcile religious beliefs that held that humanity has a unique place in the creation and a soul with the idea that innate physical traits originated from Apes.

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

While many fields of scientific inquiry are in conflict with the literal interpretations of religious texts Evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the theories of evolution, other religions aren't.
