Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution remain. People who have absorbed pop science nonsense often assume that biologists are saying they do not believe in evolution.

This site, which is a companion to the PBS series It provides teachers with materials which support evolution education and help avoid the kinds of myths that hinder it. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

It is difficult to effectively teach evolution. People who are not scientists often have a difficult time understanding the subject, and some scientists even use a definition which confuses it. This is especially applicable to debates about the meaning of the word itself.

It is therefore essential to define the terms used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful manner. It is an accompanying site for the 2001 series, but also a resource on its own. The information is presented in an organized manner that makes it easier to navigate and comprehend.

The site defines terms like common ancestor, the gradual process, and adaptation. These terms help to frame the nature of evolution as well as its relationship to other concepts in science. The site provides an overview of the manner in which evolution has been examined. This information will help to dispel the myths that are created by the creationists.

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

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

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

Deoxyribonucleic acid: A large biological molecule that contains the information required for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is the relationship between two species where evolution of one species influence evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts.

Origins

Species (groups which can interbreed), evolve through a series of natural changes in their offspring's traits. These changes are caused by a variety of factors that include natural selection, genetic drift and mixing of gene pools. The development of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food resources and habitat can slow or speed up the process.

The Evolution site traces the emergence of various groups of animals and plants over time and focuses on the most significant transitions that occurred in each group's history. It also explores the evolutionary history of humans which is crucial for students to know.

When Darwin wrote the Origin, 에볼루션 사이트 only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, 에볼루션 무료 바카라 which was first published in 1858, a year after the first edition of The Origin.

The site is primarily one of biology, but it also contains a lot of information on geology and 에볼루션 바카라 사이트 paleontology. Among the best 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 distribution of a few fossil groups listed on the site.

The site is a companion for a PBS television series, but it can also be used as a source for teachers and students. The site is very well-organized and offers clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. In particular there are links to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology, the study of these creatures within their geological context is a superior method of study over the current observational or experimental methods of studying evolutionary phenomena. In addition to studying processes and events that take place regularly or 에볼루션 룰렛 (www.hondacityclub.com published an article) over a long period of time, paleobiology allows to examine the relative abundance of various groups of organisms and their distribution in space over geological time.

The website is divided into a variety of ways to learn about evolution, including "Evolution 101," which takes the viewer on a liner path through the scientific process and the evidence supporting the theory of evolution. The path also examines myths about evolution and also the history of evolutionary thinking.

Each of the other major sections of the Evolution site is equally created, with resources that support a variety of educational levels and pedagogical styles. The site offers a wide array of multimedia and interactive resources that include videos, animations, and virtual labs in addition to general textual content. The breadcrumb-like arrangement of the content aids in navigation and orientation on the massive web site.

The page "Coral Reef Connections", for example, gives a brief overview of the coral's relationships and interactions with other organisms, and then zooms in on one clam that can communicate with its neighbors and react to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to many topics in evolutionary biology. The content also includes an overview of the importance of natural selection and the concept of phylogenetic analysis which is a crucial method to understand evolutionary change.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A vast collection of books helps in teaching evolution across all disciplines of life science.

One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that provides the depth and breadth of its educational resources. The site has a wide array of interactive learning modules. It also features a nested "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the field of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page highlighting John Endler's experiments in artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related to evolution. The content is organized into curriculum-based paths that parallel the learning goals established in the standards for biology. It contains seven videos that are designed for classroom use. These are available to stream or purchase as DVDs.

Evolutionary biology remains a field of study that has many important questions, such as what triggers evolution and how quickly it occurs. This is particularly relevant to human evolution, where it has been difficult to reconcile the notion that the innate physical characteristics of humans derived from apes and religions that believe that humanity is unique among living things and has a special place in creation with soul.

There are also a number of other ways evolution can occur, with natural selection as the most widely accepted theory. Scientists also study different types like mutation, genetic drift and sexual selection.

While many scientific fields of inquiry are in 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 to evolution while others haven't.
