Evolution Site - Teaching About Evolution

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

This site, which is a complement to the PBS program offers teachers resources that support the evolution of education, while avoiding the kinds of misconceptions which undermine it. It's organized in a "bread crumb" format to aid in navigation and orientation.

Definitions

It's difficult to effectively teach evolution. It is often misunderstood by non-scientists, and even scientists have been guilty of using a definition that confuses the issue. This is particularly relevant when discussing the meaning of the words themselves.

As such, it is crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful way. It is a companion for the 2001 series, but it is 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 frame the nature of evolution and its relationship to evolution to other concepts in science. The website then provides an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel the myths created by creationists.

It is also possible to access a 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 a result of natural selection, which happens when organisms that have better-adapted characteristics are more likely to survive and reproduce than those with less adaptable traits.

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 contains the information required for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are the cause of new genetic information in cells.

Coevolution: A relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or host and parasite.

Origins

Species (groups of individuals that are able to interbreed) change through natural changes in the traits of their offspring. These changes are caused by a variety of factors that include natural selection, genetic drift and gene pool mixing. The development of new species can take thousands of years. Environmental conditions, like climate change or competition for food resources and habitat can impede or accelerate the process.

The Evolution site tracks the development of a variety of groups of animals and plants over time and focuses on the most significant changes that took place in the history of each group. It also explores the evolutionary history of humans, a topic that is crucial for students to know.

Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans were discovered. Among them was the famous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was one year before the first edition of the Origin was published, it's highly unlikely that Darwin had heard or seen of it.

While the site is focused on biology, it also contains a wealth of information about geology and paleontology. The most impressive features on the site are a timeline of events which show how climatic and geological conditions have changed over time, and a map of the distribution of a few of the fossil groups featured on the site.

The site is a companion for the PBS television series, but it can also be used as a resource by 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 specialized elements of the museum's web site. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology is the study of these creatures within their geological context, has many advantages over modern observational or experimental methods for exploring 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 species of animals in space over the course of the geological time.

The site is divided up into several options to learn about evolution. One of the paths, "Evolution 101," guides the user through the nature and evidence of evolution. The course also focuses on common misconceptions about evolution and the history of evolutionary thought.

Each of the other major sections of the Evolution site is equally constructed, with materials that can support a variety of different pedagogical levels and curriculum levels. In addition to the standard textual content, the site also has an array of multimedia and interactive content, such as videos, animations, and virtual laboratories. The breadcrumb-like structure of the content helps with navigation and orientation on the massive website.

The page "Coral Reef Connections" For instance, it provides a comprehensive overview of coral relationships, their interaction with other organisms, and then is enlarged to show one clam, which is able communicate with its neighbors and react to changes in the water conditions that occur on the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to the broad range of topics in evolutionary biology. The information also includes a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a crucial tool for understanding the evolution of change.

Evolutionary Theory

For biology students, evolution is a key thread that weaves together all branches of the field. A vast collection of books helps in teaching evolution across the disciplines of life sciences.

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that offers both the depth and the breadth in terms of its educational resources. The site offers a variety of interactive learning modules. It also features a nested "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. For example an animation that explains the notion of genetic inheritance leads to a page that highlights John Endler's experiments in artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives set out in the standards for biology. It includes seven short videos specifically designed for use in the classroom, 에볼루션 슬롯게임사이트 - http://www.1moli.Top/home.php?mod=space&uid=864722, and can be streamed for 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 the speed at which it happens. This is especially applicable to human evolution where it has been difficult to reconcile that the physical traits of humans were derived from apes with religions that believe that humanity is unique among living things and has an exclusive place in the creation, with a soul.

Additionally there are a variety of ways in which evolution could occur, with natural selection being the most widely accepted theory. Scientists also study other types such as genetic drift and sexual selection.

While many fields of scientific study are in conflict with literal interpretations in religious texts, the concept of evolution biology has been a source of intense debate and 에볼루션 바카라사이트 (news) resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, while others haven't.
