Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution remain. Pop science nonsense has led people to think that biologists don't believe in evolution.

This rich website - companion to the PBS series - provides teachers with materials that support evolution education and avoid the kinds of myths that hinder it. It's organized in a "bread crumb" format to make navigation and orientation easier.

Definitions

Evolution is a complex and difficult subject matter to teach effectively. Many non-scientists are unable to grasp the concept, and some scientists even use a definition which confuses it. This is especially relevant to debates about the definition of the word itself.

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 an accompaniment to the 2001 series, but also a resource on its own. The material is presented in a structured manner that makes it simpler to navigate and comprehend.

The site defines terms such as common ancestor, the gradual process and adaptation. These terms help to define the nature of evolution as well as its relationship to other scientific concepts. The site then offers an overview of how the concept of evolution has been tested and validated. This information can be used to dispel myths that have been created by creationists.

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

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

Common ancestor: The latest common ancestor of two or more different species. By analyzing DNA from these species it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A huge biological molecular that holds the information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, referred to as chromosomes. Mutations are the source of new genetic information within cells.

Coevolution: A relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be seen in the interactions between predator and prey, or parasites and hosts.

Origins

Species (groups of individuals that are able to interbreed) change through natural changes in the characteristics of their offspring. These changes are caused by a variety such as natural selection, genetic drift, and gene pool mixing. The evolution of a new species can take thousands of years and the process could be slowed down or speeded up by environmental conditions such as climate change or competition for food or habitat.

The Evolution site traces the emergence of a number of different animal and 에볼루션 바카라사이트 plant groups through time, 에볼루션 바카라 체험 focusing on the major shifts that occurred throughout each group's history. It also focuses on the human evolutionary roots, a topic that is especially important for students to know.

Darwin's Origin was written in 1859, when only a few antediluvian fossils of human beings had been discovered. The famous skullcap, 에볼루션 바카라 무료 with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was published in 1858, one year after the publication of the first edition of The Origin.

The site is primarily an online biology resource however it also includes lots of information about paleontology and geology. One of the most appealing features on the site are a series of timelines which show the way in which climatic and geological conditions have changed over time, and an outline of the geographical distribution of some of the fossil groups featured on the site.

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

Diversity

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

The site is divided into various pathways to understanding evolution which include "Evolution 101," which takes the user on a linear 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 on the Evolution website is equally well-developed, with materials that can be used to support a variety of educational levels and teaching styles. The site offers a wide array of multimedia and interactive resources, including videos, animations, and virtual laboratories in addition to general textual content. The content is presented in a nested bread crumb fashion that aids navigation and orientation within the vast Web site.

For example the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interactions with other organisms. Then, it concentrates on a specific clam that is able to communicate with its neighbours and respond to changes in the water conditions that take place 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 material includes an overview of the importance of natural selection and the concept of phylogenetics as a key method for understanding the evolution of changes.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life science.

One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both the depth and breadth of its educational resources. The site offers a variety of interactive learning modules. It also features a "bread crumb structure" that helps students move away from the cartoon-like style used in Understanding Evolution and 에볼루션 바카라 무료 onto elements of this vast website that are closely linked to the fields of research science. For example an animation that introduces the notion of genetic inheritance leads to a page that highlights John Endler's experiments in artificial selection using guppies in the ponds of his native country of Trinidad.

Another helpful resource is the Evolution Library on this site, which has an extensive multimedia library of assets that are related to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives outlined in the biology standards. It contains seven short videos intended for use in the classroom. They can be viewed online or purchased as DVDs.

A number of important questions remain at the core of evolutionary biology, including what causes evolution to occur and the speed at which it occurs. This is particularly true for humans' evolution where it was a challenge to reconcile religious beliefs that held that humans have a distinct place in creation and 에볼루션 a soul with the notion that our physical traits evolved from apes.

In addition, there are a number of ways that evolution can occur, with natural selection being the most widely accepted theory. However, scientists also study other kinds of evolution like mutation, genetic drift and sexual selection, among others.

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