Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, misconceptions persist about evolution. People who have been exposed to pop science nonsense often assume that biologists claim they do not believe in evolution.

This rich Web site, which is a complement to the PBS program that provides teachers with resources that support the evolution of education, while avoiding the kinds of misconceptions that make it difficult to understand. It's laid out in the "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and difficult subject matter to teach well. Many non-scientists are unable to grasp the concept and some scientists employ a definition that confuses it. This is especially true when it comes to discussions on the meaning of the word itself.

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

The site defines terms such as common ancestor, gradual process and so on. These terms help frame the nature and relationship of evolution to other scientific concepts. The site also provides an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel the myths created by creationists.

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

The process of adaptation is the tendency of heritable traits to become more suitable to their environment. This is a result of natural selection, which occurs when organisms that are better adapted traits are more likely survive and reproduce than those with less adaptable traits.

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

Deoxyribonucleic Acid: A large biological molecular containing the information needed for 무료 에볼루션 cell replication. The information is contained in a sequence of nucleotides that are strung together to form long chains, called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be observed through the interaction between predator 에볼루션 블랙잭 and prey, or parasites and hosts.

Origins

Species (groups of individuals who can interbreed) change through an array of natural changes in the traits of their offspring. The causes of these changes are many factors, such as natural selectisticated realms of research science. There are links to John Endler's experiments with guppies, which illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and has many advantages over the current observational and experimental methods for analyzing evolutionary phenomena. Paleobiology is able to study not only processes and events that take place regularly or over time, but also the distribution and frequency of different groups of animals across geological time.

The website is divided into various paths to learning evolution that include "Evolution 101," which takes the viewer on a liner path through the scientific process and the evidence to support the theory of evolution. The path also reveals common misconceptions about evolution as well as the evolution theory's history.

Each of the other major sections of the Evolution site is equally well created, with resources that can be used to support a range of different pedagogical levels and curriculum levels. In addition to the general textual content, the site offers an array of interactive and multimedia resources including video clips, animations, and virtual laboratories. The content is laid out in a nested bread crumb style that facilitates navigation and orientation on the Web site.

The page "Coral Reef Connections" For instance, it provides an overview of the relationships between corals and interactions with other organisms, and then zooms in on one clam that can communicate with its neighbours and respond to changes in the water conditions that occur on the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a broad spectrum of topics in evolutionary biology. The content includes a discussion on the role of natural selectivity and the concept of phylogenetics analysis which is a crucial tool for understanding evolutionary change.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A rich collection of resources supports teaching about evolution across the life sciences.

One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both depth as well as broadness in terms of educational resources. The site has a variety of interactive learning modules. It also has an "bread crumb structure" that allows students to move away from the cartoon-like style that is used in Understanding Evolution and onto elements on this site that are more closely related to the worlds of research science. An animation that introduces the concept of genetics links to a page about John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.

Another useful resource is the Evolution Library on this Web website, which includes an extensive library of multimedia resources related to evolution. The content is organized according to curriculum-based paths that parallel the learning goals established in the standards for biology. It contains seven videos designed specifically for use in the classroom, and can be streamed at no cost or purchased on DVD.

A variety of crucial questions remain at the core of evolutionary biology, such as the factors that trigger evolution and the speed at which it occurs. This is especially true for human evolution, where it has been difficult to reconcile the notion that the physical traits of humans derived from apes, and the religious beliefs that hold that humans are unique in the universe and 에볼루션 사이트 무료 에볼루션체험 (you can try these out) has an enviable place in creation, with a soul.

Additionally, there are a number of ways in which evolution could occur and natural selection is the most widely accepted theory. However scientists also study other kinds of evolution, such as genetic drift, mutation, and sexual selection, among others.

While many fields of scientific inquiry conflict with literal interpretations of the Bible evolutionary biology has been the subject of intense controversy and 에볼루션 무료체험 resistance from religious fundamentalists. Certain religions have embraced their beliefs to evolution while others haven't.
