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 are saying they don't believe in evolution.

This site, which is a companion to the PBS series - provides teachers with materials that support evolution education and avoids the kinds of misinformation that can make it difficult to understand. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to properly teach evolution. It is often misunderstood even by non-scientists, and even scientists are guilty of using definitions that confuse the issue. This is especially true when discussing the meaning of the words themselves.

It is therefore crucial to define the terms that are used in evolutionary biology. The website for the PBS show, 에볼루션 바카라 사이트 코리아; Xojh.Cn, Understanding Evolution, does this in a simple and efficient way. The site serves as an accompanying site for the 2001 series, but also a resource on its own. The content is presented in a structured manner that makes it simpler to navigate and comprehend.

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 concepts in science. The site gives a comprehensive overview of the manner in which evolution has been tested. This information can be used to dispel misconceptions that have been created by creationists.

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

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

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

Deoxyribonucleic acid: A massive biological molecule that contains information required for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are responsible for the creation of new genetic information within cells.

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

Origins

Species (groups which can interbreed) develop through a series natural changes in the traits of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental circumstances, such as climate change or competition for food or habitat can slow or speed up the process.

The Evolution site tracks the evolution of various species of plants and 에볼루션 바카라 체험 animals over time and focuses on the most significant transitions that occurred in the evolution of each group's history. It also focuses on human evolution, which is a topic that is of particular interest to students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was one year after the first edition of the Origin appeared, it is extremely unlikely that Darwin had ever heard of it.

While the site focuses on biology, it contains a wealth of information about geology and paleontology. Among the best features on the site are a series of timelines that illustrate the way in which climatic and 무료에볼루션 geological conditions have changed over time, as well as an interactive map of the distribution of some fossil groups that are featured on the site.

The site is a companion for the PBS TV series but it can also be used as a source for teachers and students. The site is well-organized and provides clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features of the museum's website. These links make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are links to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in many species of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and has many advantages over the modern observational and research methods in its exploration of evolutionary phenomena. In addition to studying processes and events that occur regularly or over a lengthy period of time, paleobiology is able to examine the diversity of kinds of organisms as well as their distribution throughout the course of geological time.

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

Each of the main sections of the Evolution website is equally well-designed, with materials that can be used to support a variety of curriculum levels and teaching styles. The site has a range of interactive and multimedia resources that include video clips, animations and 에볼루션카지노사이트 virtual labs as well as general textual content. The breadcrumb-like structure of the content assists with navigation and orientation on the large web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and 에볼루션바카라 interactions with other organisms, and then zooms in on one clam that can communicate with its neighbours and respond to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a wide range of topics in evolutionary biology. The information also includes a discussion of the role of natural selection and the concept of phylogenetic analysis which is a key tool in understanding evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A wide range of resources helps teachers teach about evolution across the life sciences.

One resource, [empty] which is a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that offers both depth and breadth in its educational resources. The site has a wide array of interactive learning modules. It also has an encased "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely linked to the field of research science. For instance an animation that explains 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 is a vast multimedia library of resources that are associated to evolution. The content is organized according to curriculum-based paths that parallel the learning objectives outlined in the standards for biology. It contains seven videos designed specifically for use in classrooms, and can be streamed at no cost or purchased on DVD.

A number of important questions remain in the midst of evolutionary biology, including what causes evolution to occur and how fast it occurs. This is particularly true for the evolution of humans which was a challenge to reconcile religious beliefs that humanity has a unique place in creation and a soul with the notion that human beings have innate physical traits evolved from Apes.

There are a myriad of other ways in which evolution can occur and natural selection being the most popular theory. Scientists also study other types such as mutation, genetic drift and sexual selection.

While many fields of scientific inquiry have a conflict with literal interpretations of religious texts, evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, others aren't.
