Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, misconceptions persist about the evolution. People who have been exposed to pop science nonsense often assume that biologists are saying they don't believe in evolution.

This site, which is a companion to the PBS program offers teachers resources which support evolution education while avoiding the types of misconceptions which undermine it. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complicated and difficult subject to teach effectively. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is especially applicable to discussions about the meaning of the word itself.

As such, it is important to define terms that are 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 is also an independent resource. The content is presented in a nested fashion that aids navigation and orientation.

The site defines terms such as common ancestor, the gradual process and adaptation. These terms help to frame the nature of evolution as well as its relation to other concepts in science. The site then offers 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 access a glossary which includes terms used in evolutionary biology. These terms include:

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

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 large biological molecular that contains the information required for cell replication. The information is contained in a sequence of nucleotides that are strung together to form long chains, referred to as chromosomes. Mutations are the source of new genetic information in cells.

Coevolution is a relation between two species, where the evolutionary changes of one species are influenced evolutionary changes of the other. Coevolution can be observed through the interaction between predator and prey, or parasite and hosts.

Origins

Species (groups of individuals who can interbreed) evolve through an array of natural changes in the traits of their offspring. The changes can be caused by a variety of causes such as natural selection, genetic drift, and gene pool mixing. The evolution of new species can take thousands of years. Environmental conditions, 에볼루션 바카라 like changes in the climate or competition for food or habitat can impede or accelerate the process.

The Evolution site tracks through time the evolution of various animal and plant groups with a focus on major changes in each group's past. It also examines the evolution of humans and is a subject that is of particular interest to students.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. One of them was the infamous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap when it was published in 1858, a year after the publication of the first edition of The Origin. Origin.

The site is mostly one of biology, but it also contains a lot of information on geology and paleontology. The Web site has several aspects that are quite impressive, such as an overview of how climate and geological conditions have changed over the course of time. It also features an interactive map that shows the location of fossil groups.

The site is a companion for the PBS television series, but it could be used as a source for teachers and students. The site is well-organized, and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features of the museum website. These links make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are also links to John Endler's experiments with guppies. They demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of animals, plants, and insects. Paleobiology, the study of these creatures within their geological environment offers many advantages over the current observational or experimental methods for exploring evolutionary phenomena. In addition to exploring processes and events that occur regularly or over a lengthy period of time, paleobiology is able to examine the relative abundance of different species of organisms and their distribution in space over the course of geological time.

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

Each of the other major sections of the Evolution site is equally developed, with materials that support a variety of curriculum levels and pedagogical styles. The site offers a wide array of interactive and multimedia content that include animations, video clips and virtual laboratories as well as general textual content. The content is presented in a nested bread crumb-like fashion that helps with navigation and 에볼루션 무료 바카라 [Tp45.Ru] orientation on the web site.

For instance, the page "Coral Reef Connections" provides an overview of coral relationships and their interactions with other organisms, then zooms in on a single clam that is able to communicate with its neighbors and react to changes in water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The material includes a discussion on the role of natural selectivity and the concept phylogenetics analysis as a key tool to understand evolutionary change.

Evolutionary Theory

For biology students, evolution is a key thread that binds all branches of the field. A vast collection of resources supports teaching about evolution across all life sciences.

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of an Web site that provides the depth and the breadth in terms of its educational resources. The site features a wide range of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. For instance, an animation introducing the concept of genetic inheritance links to a page that highlights John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of materials that deal to evolution. The content is organized in curricula-based paths that correspond to the learning goals set forth in the biology standards. It contains seven videos specifically designed for use in the classroom, and can be streamed for no cost or 에볼루션사이트 purchased on DVD.

Many important questions remain in the midst of evolutionary biology, including what triggers evolution and how fast it happens. This is especially true for the evolution of humans which was a challenge to reconcile religious beliefs that held that humanity has a unique position in the universe and a soul, with the notion that our physical traits evolved from apes.

In addition there are a variety of ways that evolution can occur, with natural selection being the most widely accepted theory. Scientists also study other types such as mutation, genetic drift and sexual selection.

Many fields of inquiry are in conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, others aren't.
