Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution persist. 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 series - provides teachers with materials which support evolution education and avoids the kinds of misinformation that can hinder it. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to effectively teach evolution. Many non-scientists are unable to grasp the concept and some scientists use a definition which confuses it. This is especially true when it comes to debates about the meaning of the word itself.

As such, it is essential to define terms used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient manner. The site is a companion site to the show that premiered in 2001, 무료 에볼루션 무료체험 (have a peek at this web-site) but can also function as an independent resource. The content is presented in a nested manner which aids navigation and orientation.

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

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

Adaptation: The tendency of heritable characteristics to become more suitable to a particular setting. This is the result of natural selection, which happens when organisms with better-adapted traits are more likely survive and reproduce than those with less adapted traits.

Common ancestor: The most recent common ancestor of two or more different species. The common ancestor can be identified through analyzing the DNA of those species.

Deoxyribonucleic acid: A massive biological molecule that holds the information required for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form long chains, also known as chromosomes. Mutations are the source of new genetic information within cells.

Coevolution is the relationship between two species, where the evolution of one species are influenced evolutionary changes in the other. Coevolution is evident in the interaction of predator and prey, or parasite and hosts.

Origins

Species (groups of individuals that are able to interbreed) evolve through a series of natural changes in the traits of their offspring. The causes of these changes are various factors, including natural selection, gene drift, and mixing of the gene pool. The development of a new species could take tce of ecology in evolutionary theory.

Diversity

The evolution of life has produced many species of plants, animals and insects. Paleobiology, the study of these creatures in their natural environment, has many advantages over the current observational or experimental methods for 무료 에볼루션 exploring evolutionary processes. In addition to exploring the processes and events that happen regularly or over a lengthy period of time, paleobiology is able to examine the diversity of species of organisms and their distribution in space over geological time.

The site is divided into various pathways to understanding evolution which include "Evolution 101," which takes the viewer on a line through the nature of science and the evidence that supports the theory of evolution. The path also explores misconceptions about evolution and the background of evolutionary thought.

Each of the other main sections of the Evolution site is equally well created, with resources that can be used to support a range of curriculum levels and pedagogical styles. The site has a range of multimedia and interactive resources, including videos, animations, and virtual labs, 에볼루션 슬롯 in addition to its general textual content. The content is laid out in a nested bread crumb style that facilitates navigation and 에볼루션 바카라 체험 orientation within the large Web site.

For example the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms. Then, it narrows down to a single clam that can communicate with its neighbors and respond to changes in the water conditions that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages gives a good introduction to the many areas of evolutionary biology. The content includes a discussion on the role of natural selectivity and the concept of phylogenetics as a key tool for understanding evolutionary change.

Evolutionary Theory

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

One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that offers both depth and a variety of educational resources. The site has a wide array of interactive learning modules. It also features an embedded "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. For instance an animation that introduces the concept of genetic inheritance links to a page that highlights John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives set out in the biology standards. It contains seven videos specifically designed 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 the factors that trigger evolution and the speed at which it occurs. This is especially true for the evolution of humans where it was a challenge to reconcile religious beliefs that held that humanity has a special place in the creation and 무료 에볼루션 a soul, with the notion that our physical traits evolved from apes.

Additionally there are a variety of ways that evolution could be triggered, 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 conflict with literal interpretations of religious texts, evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
