Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution persist. Pop science nonsense has led people to believe that biologists aren't believers in evolution.

This rich Web site - companion to the PBS series It provides teachers with materials that promote evolution education and help avoid the kinds of myths that make it difficult to understand. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It's not easy to properly teach evolution. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is particularly relevant when discussing the nature of the words themselves.

It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The website is a companion to the series that first aired in 2001, but also functions as an independent resource. The content is presented in a nested manner that assists in navigation and orientation.

The site defines terms such as common ancestor (or 에볼루션카지노 common ancestor), gradual process and adaptation. These terms help frame the nature and relationship of evolution to other scientific concepts. The website provides a summary of the manner the concept of evolution has been examined. This information can help dispel the myths that are created by the creationists.

You can also access a glossary which contains terms used in evolutionary biology. These terms include:

Adaptation is the tendency of heritable traits to become more suitable to their environment. This is the result of natural selection. Organisms with more adaptable traits are more likely than those with less adaptable characteristics to survive and reproduce.

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

Deoxyribonucleic acid: A massive biological molecule that contains information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

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

Origins

Species (groups that can crossbreed) change by a series of natural variations in the traits of their offspring. These changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, like climate changes or competition for food and habitat, can slow or accelerate the process.

The Evolution site follows the evolution of various groups of animals and plants, focusing on major transitions in each group's history. It also examines the evolutionary origin of humans and humans, a subject that is especially important for students to know.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans had been found. One of them was the infamous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was first published in 1858, a year after the publication of the first edition of The Origin. Origin.

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

While the site is a companion piece to the PBS television show however, it can stand on its own as an excellent resource for teachers and students. The site is well-organized and provides easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features of the museum website. 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, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in an array of animals, plants and insects. Paleobiology, the study of these creatures within their geological context offers many advantages over modern observational or experimental methods of studying evolutionary phenomena. Paleobiology is able to study not only the process and events that happen regularly or over time but also the relative abundance and distribution of different species of animals in space throughout geological time.

The site is divided into several optional ways to learn about evolution, including "Evolution 101," which takes the viewer on a line through the nature of science and the evidence to support the theory of evolution. The course also focuses on the most common misconceptions about evolution, 에볼루션 코리아 as well as the history of evolutionary thought.

Each of the other sections of the Evolution site is similarly constructed, with materials that can be used to support a range of curriculum levels and pedagogical styles. In addition to the general textual content, the site features an extensive selection of multimedia and 에볼루션카지노 interactive resources including videos, animations, and virtual labs. The content is laid out in a nested bread crumb fashion that aids navigation and orientation on the web site.

For instance, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interactions with other organisms, then concentrates on a specific clam that can communicate with its neighbors and react to changes in water conditions at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to the many areas of evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis which is a crucial method to understand evolutionary changes.

Evolutionary Theory

For biology students the concept of evolution is a major thread that connects all branches of the field. A rich collection supports teaching evolution across all disciplines of life sciences.

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

Another resource that is worth mentioning is the Evolution Library on this Web site, which has an extensive multimedia library of assets related to evolution. The content is organized according to curricula-based pathways that correspond to the learning goals established in the standards for biology. It contains seven videos designed specifically for use in classrooms, and can be streamed for free or purchased on DVD.

Evolutionary biology remains an area of study that has many important questions, including what triggers evolution and how fast it happens. This is particularly relevant for humans' evolution, where it was difficult to reconcile religious beliefs that humanity has a unique place in creation and a soul, with the idea that innate physical traits were derived from the apes.

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

Many fields of inquiry are in conflict with 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.
