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 claim they don't believe in evolution.

This rich Web site - 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 arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complex and challenging subject to teach effectively. It is often misunderstood even by non-scientists, and even scientists are guilty of using an interpretation that is confusing the issue. This is particularly relevant when discussing the meaning of the words themselves.

It is therefore important to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. It is an accompanying site for the 2001 series, and also a resource of its own. The material is presented in a nested fashion that aids navigation and orientation.

The site defines terms such as common ancestor 에볼루션 사이트 and gradual process. These terms help to frame the nature of evolution as well as its relation to other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and confirmed. This information can be used to dispel the myths that have been created by the creationists.

It is also possible to find the 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 the result of natural selection. Organisms with more adaptable characteristics are more likely than those with less-adapted characteristics to survive and reproduce.

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

Deoxyribonucleic acid: A large biological molecule that holds the information required for cell replication. The information is stored in nucleotide sequences, which are strung into long chains called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution is a relationship between two species where evolutionary changes 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 who can interbreed) change through a series of natural changes in the characteristics 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 new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for 에볼루션 바카라 무료체험 food resources and habitat can slow or speed up the process.

The Evolution site traces through time the evolution of various species of plants and animals, focusing on major transitions in each group's history. It also focuses on human evolution and is a subject that is particularly important to students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year after the first edition of the Origin was published, it's highly unlikely that Darwin had seen or heard of it.

While the site focuses on biology, 에볼루션 바카라 it also contains a wealth of information about geology and paleontology. The site offers a number of features that are particularly impressive, including an overview of the way that climate and geological conditions have changed over time. It also includes an interactive map that shows the location of fossil groups.

Although the site is a companion to a PBS television series, it also stands on its own as an excellent resource for teachers and students. The site is well-organized and 무료에볼루션 offers easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features of the museum's website. These hyperlinks help users move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly, there are links to John Endler's research with guppies that illustrate 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 is a superior method of study over modern observational or experimental methods for exploring evolutionary processes. Paleobiology can examine not only the process and events that happen regularly or over time but also the relative abundance and distribution of various animal groups in space throughout geological time.

The Web site is divided into several optional paths to learning evolution which include "Evolution 101," which takes the viewer on a line through the nature of science and the evidence to support the theory of evolution. The course also focuses on misconceptions regarding evolution, and also the history of evolutionary thinking.

Each of the other main sections of the Evolution site is similarly constructed, with materials that support a variety of curriculum levels and pedagogical styles. The site has a range of interactive and multimedia content that include videos, animations, 에볼루션 사이트 and virtual labs as well as general textual content. The breadcrumb-like organization of the content helps with navigation and orientation on the vast Web site.

The page "Coral Reef Connections" For instance, 에볼루션 사이트 the page "Coral Reef Connections" provides an overview of the coral's relationships, their interaction with other organisms, and then zooms in to one clam, which can communicate with its neighbours and respond to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, gives a good introduction to a variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis, which is a crucial tool for understanding the evolution of change.

Evolutionary Theory

Evolution is a common thread that runs through all branches of biology. A vast collection of resources can help teachers teach about evolution across all life sciences.

One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that provides the depth and the broadness in terms of educational resources. The site offers a range of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the world of research science. For example an animation that introduces the concept of genetic inheritance links to a page that highlights John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of materials that deal to evolution. The contents are organized into curriculum-based paths that parallel the learning goals established in the biology standards. It contains seven videos designed specifically for use in classrooms, and can be streamed at no cost or purchased on DVD.

Evolutionary biology is still a field of study that poses many important questions, such as the causes of evolution and how fast it occurs. This is particularly relevant to human evolution, which has made it difficult to reconcile that the physical characteristics of humans were derived from apes, and 무료에볼루션 the religious beliefs that hold that humanity is unique among living things and has an exclusive place in the creation with soul.

In addition, there are a number of ways that evolution can occur with natural selection being the most popular theory. Scientists also study other types like mutation, genetic drift and sexual selection.

While many scientific fields of inquiry conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
