Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. People who have been exposed to popular science myths often assume that biologists don't believe in evolution.

This rich Web site - companion to the PBS series - provides teachers with materials that support evolution education and avoids the kinds of myths that undermine it. It's organized in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to effectively teach evolution. People who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. This is especially relevant when discussing the nature of the words themselves.

It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site is a companion site to the series that first aired in 2001, but can also function as an independent resource. The content is presented in an organized way that makes it easy to navigate and comprehend.

The site defines terms like common ancestor, the gradual process and adaptation. These terms help frame the nature and relationship of evolution with other scientific concepts. The site then offers an overview of how the concept of evolution has been vetted and validated. This information can be used to dispel misconceptions that have been created by creationists.

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

Adaptation is the tendency of hereditary traits to become more suited to the environment. This is a result of natural selection. Organisms with better-adapted 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. By analyzing the DNA from these species, it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A huge biological molecular that contains the information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution is the relationship between two species in which the evolutionary changes of one species are influenced evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or the parasite and the host.

Origins

Species (groups of individuals that are able to interbreed) evolve through a series of natural changes in the traits of their offspring. The changes can be triggered by a variety of causes that include natural selection, genetic drift and gene pool mixing. The evolution of a new species can take thousands of years, and the process can be slowed down or accelerated by environmental factors like climate change or competition for food or habitat.

The Evolution site tracks through time the emergeu/go?http://planforexams.com/q2a/user/maskbite58">[Redirect-302] research methods for 무료에볼루션 studying evolutionary phenomena. Paleobiology is able to study not only the process and events that happen regularly or over time, but also the distribution and frequency of different groups of animals in space throughout the geological time.

The website is divided into different options to gain knowledge about evolution. One of these paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The path also explores the most common misconceptions about evolution, as well as the evolution of thought.

Each of the other major sections of the Evolution site is equally developed, with materials that support a variety of educational levels and pedagogical styles. The site offers a wide array of multimedia and interactive resources that include animations, video clips and virtual laboratories in addition to general textual content. The content is organized in a nested, bread crumb-like fashion that helps with navigation and 에볼루션 바카라 코리아 (relevant resource site) orientation on the Web site.

For instance the page "Coral Reef Connections" provides an overview of coral relationships and their interaction with other organisms, then narrows down to a single clam that is able to communicate with its neighbours and respond to changes in the water conditions at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages provides an excellent introduction to many topics in evolutionary biology. The content also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is a key tool in understanding evolutionary changes.

Evolutionary Theory

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

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that provides the depth and the broadness in terms of educational resources. The site offers a variety of interactive learning modules. It also features an embedded "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely tied to the field of research science. For example, an animation introducing the notion of genetic inheritance leads to a page highlighting John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of assets related with evolution. The content is organized in curricula-based paths that correspond to the learning objectives set out in the 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 an area of study that poses many important questions to answer, such as what causes evolution and how quickly it happens. This is particularly relevant for humans' evolution where it was a challenge to reconcile religious beliefs that held that humanity has a unique position in the universe and a soul, with the idea that innate physical traits originated from apes.

There are a variety of other ways evolution can occur and natural selection being the most widely accepted theory. However scientists also study different types of evolution such as mutation, genetic drift and [Redirect Only] sexual selection, among other things.

While many fields of scientific study conflict with literal interpretations found in religious texts, the concept of evolution biology has been a source of intense controversy and opposition from religious fundamentalists. Certain religions have embraced their beliefs to evolution while others haven't.
