Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. People who have absorbed popular science myths often assume that biologists claim they 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 kinds of misconceptions that can hinder it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to teach evolution well. It is often misunderstood by non-scientists and even scientists have been guilty of using definitions that confuse the issue. This is particularly true when discussing the nature of the words themselves.

It is therefore crucial to define the terms that are used in evolutionary biology. The website for 에볼루션 게이밍 the PBS show, Understanding Evolution, does this in a clear and helpful way. The site is a companion to the series that first aired in 2001, but it also functions as an independent resource. The information is organized in a way that makes it easy to navigate and comprehend.

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

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

Adaptation is the process of changing hereditary traits to become more suitable to their environment. This is a 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 distinct species. By analyzing the DNA from these species it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular containing the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution is a relation between two species where evolutionary changes of one species are influenced by evolutionary changes in the other. Coevolution can be seen through the interaction between predator and prey, or parasites and hosts.

Origins

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

The Evolution site traces the emergence of a number of different species of plants and animals over time with a focus on the key changes that took place in each group's history. It also explores human evolution and is a subject that is particularly important to students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The famous skullcap, with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap when it was published in 1858, a year following the initial edition of The Origin. Origin.

While the site is focused on biology, it offers a lot of information on geology and paleontology. The most impressive features of the website are a series of timelines which show the way in which climatic and geological conditions changed over time, and a map of the distribution of a few fossil groups that are featured on the site.

While the site is a companion to a PBS television show however, it can stand on its own as a great resource for teachers and students. The site is very well organized and provides clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated components of the museum's Web site. These hyperlinks facilitate the move from the enthralling 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 illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced a variety of plants, 에볼루션 무료체험 animals and insects. Paleobiology is the study of these creatures within their geological context and has many advantages over modern observational and experimental methods of examining evolutionary processes. Paleobiology is able to study not just the processes and events that happen regularly or over time, but also the distribution and frequency of different groups of animals in space throughout geological time.

The website is divided into various options to study the subject of evolution. One of these paths, "Evolution 101," takes the viewer through the nature and evidence of evolution. The path also explores common misconceptions about evolution as well as the history of evolutionary thought.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that support a variety levels of curriculum and 에볼루션 슬롯게임 teaching methods. The site has a range of interactive and multimedia resources, including video clips, 에볼루션 바카라 무료 무료 에볼루션체험 [right here] animations and virtual laboratories as well as general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the vast website.

For instance, 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 level of the reef. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to a variety of topics in evolutionary biology. The material includes an explanation of the significance of natural selectivity and the concept phylogenetics analysis, an important tool for understanding evolutionary change.

Evolutionary Theory

For biology students, evolution is a key thread that connects all the branches of the field. A vast collection of resources supports teaching about evolution across all life sciences.

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that offers both the depth and the breadth in terms of its educational resources. The site features a wealth of interactive learning modules. It also features a nested "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. An animation that introduces students to the concept of genetics links to a page about John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.

The Evolution Library on this website has a huge multimedia library of resources that are associated to evolution. The content is organized according to curricula-based pathways that correspond to the learning objectives set out in biology standards. It includes seven short videos specifically designed for use in classrooms. They can be streamed or purchased as DVDs.

Many important questions remain at the core of evolutionary biology, including what triggers evolution and the speed at which it occurs. This is especially true for human evolution, where it has been difficult to reconcile the notion that the innate physical characteristics of humans derived from apes with religious beliefs that hold that humans are unique among living things and has a special place in creation, with a soul.

There are a myriad of other ways in which evolution can occur including natural selection, 에볼루션 룰렛 which is the most widely accepted theory. Scientists also study other kinds such as mutation, genetic drift, and sexual selection.

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