Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution remain. People who have been exposed to the nonsense of pop science often believe 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 types of misconceptions that hinder it. It's laid out in the "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complex and challenging subject to teach effectively. It is often misunderstood by non-scientists, and even scientists are guilty of using an interpretation that is confusing the issue. This is especially applicable to debates about the meaning of the word itself.

It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site serves as an accompaniment to the 2001 series, but also a resource on its own. The information is presented in an organized manner that makes it simpler to navigate and comprehend.

The site defines terms such as common ancestor (or common ancestor), gradual process, and adaptation. These terms help to define the nature of evolution as well as its relation to other scientific concepts. The site also provides an overview of how the concept of evolution has been researched and verified. This information can help dispel the myths created by creationists.

You can also consult a glossary that includes terms that are used in evolutionary biology. These terms include:

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

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

Deoxyribonucleic acid: A huge biological molecule that holds the information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, called chromosomes. Mutations are the source of new genetic information within cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be seen through the interaction between predator and prey, or parasite and 에볼루션사이트 hosts.

Origins

Species (groups of individuals who can interbreed) develop through natural changes in the characteristics of their offspring. These changes are caused by a variety of factors that include natural selection, genetic drift, and mixing of genes. The evolution of a new species can take thousands of years, and the process could be slowed or increased by environmental conditions such as climate change or the competition for food or habitat.

The Evolution site tracks through time the evolution of different species of plants and animals and focuses on major 무료에볼루션 changes in each group's history. It also explores the evolutionary history of humans which is crucial for students to understand.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The famous skullcap, along with the associated bones were 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 when it was published in 1858, one year following the initial edition of The Origin.

The site is primarily one of biology however it also includes a lot of information on paleontology and geology. Among the best features of the website are a timeline of events that illustrate how geological and climatic conditions have changed over time, as well as an interactive map of the distribution of some of the fossil groups featured on the site.

The site is a companion for the PBS TV series but it could also be used as an educational resource by teachers and students. The site is well-organized and offers clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler’s experiments with guppies. They illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life has produced many species of animals, plants and insects. Paleobiology is the study of these creatures within their natural environment and has many advantages over modern observational and experimental methods in its exploration of evolutionary processes. Paleobiology focuses on not just the processes and 에볼루션사이트 events that occur regularly or over time but also the distribution and frequency of various animal groups across the geological time.

The site is divided into different paths that can be chosen to gain knowledge about evolution. One of the paths, "Evolution 101," walks the reader through the evolution of nature and the evidence of evolution. The path also explores misconceptions about evolution, and also the history of evolutionary thinking.

Each of the other major sections of the Evolution site is equally well created, with resources that can support a variety of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia resources that include animations, video clips and virtual laboratories in addition to general textual content. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the vast web site.

For example, the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interaction with other organisms. It then narrows down to a single clam that is able to communicate with its neighbours and respond to changes in the water conditions that occur at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages, gives a good introduction to the many areas of evolutionary biology. The material includes an explanation of the importance of natural selection and the concept of phylogenetics which is a crucial method for understanding the evolution of changes.

Evolutionary Theory

For biology students evolution is a crucial thread that connects all the branches of the field. A rich collection supports teaching evolution across all disciplines of life sciences.

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that offers both the depth and the broadness in terms of educational resources. The site offers a range 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 huge site that are closer to the world of research science. For instance an animation that introduces the idea of genetic inheritance connects to a page that highlights John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

Another useful resource is the Evolution Library on this Web website, which includes an extensive multimedia library of resources related to evolution. The content is organized into curriculum-based pathways that correspond to the learning goals set forth in biology standards. It contains seven short videos that are intended for use in the classroom. These are available to stream or purchase as DVDs.

A variety of crucial questions remain in the midst of evolutionary biology, including the factors that trigger evolution and the speed at which it occurs. This is particularly relevant to human evolution, where it's been difficult to reconcile the idea that the physical traits of humans were derived from apes with religious beliefs that claim that humans are unique in the universe and has a special place in creation, with a soul.

There are also a number of other ways in which evolution can occur including natural selection, which is the most widely accepted theory. However, scientists also study other kinds of evolution, such as genetic drift, mutation, 에볼루션바카라 (Stokes-Phelps.Technetbloggers.De) and sexual selection, among others.

While many fields of scientific study are in conflict with literal interpretations found in religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions haven't.
