Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. Pop science fiction has led a lot of people to think that biologists don't believe in evolution.

This rich Web site - companion to the PBS series offers teachers with resources that support evolution education and avoid the kinds of myths that hinder it. It's organized in the "bread crumb" format to make navigation and orientation easier.

Definitions

It's difficult to effectively teach evolution. It is often misunderstood even by non-scientists, and even scientists are guilty of using a definition that confuses the issue. This is particularly relevant to debates about the meaning of the word itself.

Therefore, it is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in a simple and efficient manner. It is an accompaniment to the 2001 series, and also a resource of its own. The information is presented in an organized way that makes it easy to navigate and comprehend.

The site defines terms like common ancestor, gradual process and adaptation. These terms help to frame the nature of evolution as well as its relation to other scientific concepts. The site provides an overview of the way the concept of evolution has been examined. This information can be used to dispel myths that have been created by the creationists.

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

The process of adaptation is the tendency of hereditary traits to become 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 survive and 무료에볼루션 reproduce.

Common ancestor: The most recent common ancestor of two or more distinct species. By studying the DNA of these species it is possible to identify the common ancestor.

Deoxyribonucleic acid: A huge biological molecule that contains information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

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

Origins

Species (groups of individuals that can interbreed) change through natural changes in the characteristics of their offspring. The changes can be caused by a variety of causes, including natural selection, genetic drift and mixing of gene pools. The evolution of a new species could take thousands of years, and the process could be slowed down or accelerated due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site tracks through time the evolution of various species of plants and animals with a focus on major changes in each group's past. It also focuses on human evolution, which is a topic that is of particular interest for students.

Darwin's Origin was published in 1859, when only a handful of antediluvian fossils of humans had been found. The famous skullcap, with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, a year after the publication of the first edition of The Origin.

The site is mostly a biology site however it also includes a lot of information on geology and 에볼루션사이트 paleontology. The most impressive features of the website are a set of timelines that illustrate how climatic and geological conditions have changed over time, and a map of the geographical distribution of some fossil groups that are featured on the site.

While the site is a companion piece to a PBS television series however, it can stand on its own as an excellent resource for teachers and students. The site is very well-organized and offers clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum Web site. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular, there are links to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of plants, 바카라 에볼루션 무료체험 (Ucgp.jujuy.edu.Ar) animals and insects. Paleobiology is the study of these creatures within their geological context, has many advantages over modern observational or experimental methods for studying evolutionary phenomena. In addition to exploring processes and events that take place regularly or over a lengthy period of time, paleobiology can be used to analyze the relative abundance of various species of organisms and their distribution across geological time.

The website is divided into several optional paths to learning evolution, including "Evolution 101," which takes the viewer on a liner path through the scientific process and the evidence to support the theory of evolution. The course also focuses on misconceptions about evolution and also the history of evolutionary thought.

Each of the main sections on the Evolution website is equally well-developed, and includes materials that support a variety curriculum levels and teaching styles. In addition to general textual content, 에볼루션 게이밍 the site features a wide range of multimedia and interactive content like video clips, animations, and virtual labs. The breadcrumb-like structure of the content assists with navigation and orientation on the vast web site.

For instance the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms, then zooms in on a single clam that can communicate with its neighbors and react to changes in the water conditions that take place at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to the broad range of topics in evolutionary biology. The content also includes an explanation of the importance of natural selection and the concept of phylogenetics which is a crucial method for understanding the evolution of change.

Evolutionary Theory

Evolution is a common thread that runs through all branches of biology. A rich collection of resources helps teachers teach about evolution across the life sciences.

One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both depth and wide range of educational resources. The site features a wealth of interactive learning modules. It also features an encased "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this large Web site closer to the field of research science. An animation that introduces students to the concept of genetics, which links to a page about John Endler's experiments with artificial selection using guppies on native ponds in Trinidad.

The Evolution Library on this website contains a large multimedia library of assets related with evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives set out in biology standards. It includes seven short videos intended for use in the classroom. These can be viewed online or purchased as DVDs.

A variety of crucial questions remain at the heart of evolutionary biology, including what triggers evolution and the speed at which it occurs. This is especially applicable to human evolution where it has been difficult to reconcile that the innate physical characteristics of humans were derived from apes and religious beliefs that claim that humanity is unique among living things and has an enviable place in creation with a soul.

There are a myriad of other ways in which evolution can occur, with natural selection as the most well-known theory. Scientists also study different types such as genetic drift and sexual selection.

While many fields of scientific study conflict with literal interpretations found in religious texts, evolution biology has been the subject of intense debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, other religions have not.
