Evolution Site - Teaching About Evolution

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

This rich Web site, a companion to the PBS program offers teachers resources that support the evolution of education while avoiding the types of misconceptions which undermine it. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It is difficult to properly teach evolution. Many non-scientists are unable to grasp the concept, and some scientists even employ a definition that confuses it. This is particularly true when discussing the meaning of the words themselves.

It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful way. The site is both a companion for the 2001 series, but also a resource on its own. The content is presented in a nested fashion that assists in navigation and orientation.

The site defines terms such as common ancestor (or common ancestor), gradual process, 에볼루션 바카라 사이트 and adaptation. These terms help to define 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 help dispel myths created by creationists.

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

Adaptation: 무료 에볼루션 무료체험 (www.Hondacityclub.Com) The tendency for heritable characteristics to become more suited to a particular environment. This is the result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adapted traits to survive and reproduce.

Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified by studying the DNA of these species.

Deoxyribonucleic Acid: A huge biological molecular containing the information needed for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are the cause of new genetic information in cells.

Coevolution is a relation between two species, where the evolution of one species are influenced evolutionary changes in the other. Coevolution can be observed in the interaction of predator 에볼루션 바카라 사이트 and prey, or parasite and hosts.

Origins

Species (groups of individuals that can interbreed) develop through a series of natural changes in the characteristics of their offspring. Changes can be caused by various factors, including natural selection, gene drift and 에볼루션바카라 mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, like climate change or 에볼루션게이밍 competition for food or habitat, can slow or accelerate the process.

The Evolution site tracks through time the evolution of various animal and plant groups and focuses on major changes within each group's past. It also focuses on the evolutionary history of humans which is especially important for students to understand.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The famous skullcap, with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, one year after the publication of the first edition of The Origin.

While the site focuses on biology, it includes a good deal of information about geology and paleontology. The most impressive features of the website are a timeline of events that illustrate how geological and climatic conditions changed over time, as well as a map of the geographical distribution of some of the fossil groups featured on the site.

The site is a companion for the PBS television series, but it could also be used as a resource for teachers and students. The site is well-organized and provides clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized features of the museum website. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are hyperlinks to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has resulted in a variety of plants, animals, and insects. Paleobiology is the study of these creatures in their geological environment offers many advantages over modern observational or experimental methods for studying evolutionary phenomena. Paleobiology focuses on not only the process and events that take place regularly or over time, but also the relative abundance and distribution of various animal groups in space over the course of the geological time.

The site is divided into a variety of pathways to understanding 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 explores common misconceptions about evolution as well as the history of evolutionary thought.

Each of the other main sections of the Evolution site is similarly created, 에볼루션 사이트 with resources that support a variety of curriculum levels and pedagogical styles. The site includes a variety of interactive and multimedia resources which include videos, animations, and virtual laboratories in addition to general textual content. The breadcrumb-like organization of the content helps with navigation and orientation on the massive Web site.

For example the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms. Then, it narrows down to a single clam that can communicate with its neighbours and respond to changes in water conditions that take place at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, offers a great introduction to the many areas of evolutionary biology. The content also includes a discussion on the significance of natural selectivity and the concept of phylogenetics analysis which is a crucial method for understanding the evolution of changes.

Evolutionary Theory

For biology students, evolution is a key thread that weaves together all the branches of the field. A wide selection of resources helps teachers teach evolution across the disciplines of life sciences.

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of an Web site that provides depth and broadness in terms of educational resources. The site offers a range of interactive learning modules. It also features a nested "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely tied to the world of research science. For example an animation that explains the idea of genetic inheritance connects to a page highlighting John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

The Evolution Library on this website is a vast multimedia library of assets related with evolution. The content is organized into curriculum-based pathways that correspond to the learning goals set forth in biology standards. It contains seven videos designed specifically for classroom use, which can be streamed for free or purchased on DVD.

Evolutionary biology is a field of study that has many important questions, including what triggers evolution and the speed at which it occurs. This is particularly relevant to human evolution, where it's been difficult to reconcile the notion that the innate physical characteristics of humans were derived from apes and religious beliefs that claim that humanity is unique in the universe and has a special place in creation. It is a soul.

Additionally there are a myriad of ways that evolution could occur, with natural selection being the most widely accepted theory. However scientists also study different kinds of evolution, such as mutation, genetic drift and sexual selection, among other things.

While many fields of scientific study are in conflict with literal interpretations in religious texts, the concept of evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
