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

Definitions

Evolution is a complicated and difficult subject to teach effectively. It is often misunderstood even by non-scientists, and even scientists use definitions that confuse the issue. This is particularly relevant when discussing the nature of the words themselves.

Therefore, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site serves as a companion for the 2001 series, but also a resource on its own. The content is presented in a nested fashion that assists in navigation and orientation.

The site defines terms like common ancestor, gradual process and adaptation. These terms help to define the nature of evolution and its relation to other concepts in science. The website then provides an overview of how the concept of evolution has been researched and confirmed. This information can be used to dispel the myths that have been created by the creationists.

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

Adaptation: The tendency for heritable characteristics to become more suitable to a particular setting. This is a result of natural selection, which happens when organisms that are better-adapted traits are more likely to survive and reproduce than those with less adapted traits.

Common ancestor (also called common ancestor): The most recent ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of those species.

Deoxyribonucleic Acid: A massive biological molecular containing the necessary information for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the source of new genetic information within cells.

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

Origins

Species (groups of individuals that are able to interbreed) evolve through natural changes in the characteristics of their offspring. The causes of these changes are 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 circumstances, such as climate change or 에볼루션 바카라 competition for food or habitat can impede or 에볼루션 코리아 accelerate the process.

The Evolution site tracks through time the evolution of various groups of animals and plants and focuses on major 무료 에볼루션 에볼루션 무료 바카라 (kingranks.com) changes in each group's past. It also explores human evolution, which is a topic that is of particular interest to students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was a year before the first edition of the Origin appeared, it is extremely unlikely that Darwin had seen or heard of it.

While the site is focused on biology, it also includes a good deal of information about geology as well as paleontology. The website has a number of aspects that are quite impressive, such as a timeline of how geological and climate conditions have changed over time. It also features an interactive map that shows the location of fossil groups.

Although the site is a companion piece to a PBS television show but it also stands on its own as an excellent source for teachers and students. The site is well-organized, and provides easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features of the museum's website. These hyperlinks facilitate the move from the cartoon-like 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. They illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life has produced many species of plants, animals and insects. Paleobiology is the study of these creatures in their natural environment and has numerous advantages over modern observational and experimental methods of examining evolutionary phenomena. In addition to examining processes and events that occur frequently or over a long period of time, 에볼루션카지노 paleobiology is able to study the relative abundance of various groups of organisms and their distribution throughout the geological time.

The website is divided into a variety of paths to learning evolution, including "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence supporting the theory of evolution. The path also explores misconceptions about evolution, and the background of evolutionary thinking.

Each of the main sections of the Evolution website is equally well-designed, with materials that are suited to a variety of levels of curriculum and teaching methods. The site offers a wide array of multimedia and interactive resources that include videos, animations, and virtual laboratories as well as general textual content. The content is organized in a nested, bread crumb fashion that aids navigation and orientation within the large Web site.

For example, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interaction with other organisms. Then, it zooms in on a single clam that is able to communicate with its neighbors and react to changes in the water conditions that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages provides an excellent introduction to a variety of topics in evolutionary biology. The information also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is a key method to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that connects all branches of biology. A vast collection of resources can help teachers teach about evolution across all life sciences.

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides the depth and the broadness in terms of educational resources. The site offers a range of interactive learning modules. It also features an "bread crumb structure" that assists students in moving away from the cartoon-like style of Understanding Evolution and onto elements on this site that are more closely connected to the worlds of research science. An animation that introduces the concept of genetics links to a page highlighting John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.

Another resource that is worth mentioning is the Evolution Library on this web site, which has an extensive collection of multimedia assets connected to evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives set out in biology standards. It includes seven short videos that are intended for use in the classroom. They can be viewed online or purchased as DVDs.

Evolutionary biology is a field of study that poses many important questions, including what causes evolution and 무료 에볼루션 how quickly it occurs. This is particularly true for the evolution of humans 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 notion that human beings have innate physical traits were derived from Apes.

There are a myriad of other ways evolution can occur including natural selection, which is the most popular theory. However scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among other things.

While many fields of scientific study have a conflict with literal interpretations found in religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, while others haven't.
