10 Evolution Site Strategies All The Experts Recommend

Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, there are still a lot of misconceptions regarding evolution. People who have absorbed popular science myths often assume that biologists do not believe in evolution.

This site, a companion to the PBS program offers teachers resources that promote evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to properly teach evolution. People who are not scientists often have a difficult time understanding the subject, and some scientists even use a definition that confuses it. This is especially applicable to discussions about the nature of the word.

As such, it is crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site is a companion site to the show which first aired in 2001, but it also functions as an independent resource. The material is presented in a way that aids navigation and orientation.

The site defines terms such as common ancestor, gradual process and adaptation. These terms help to define the nature of evolution and its relationship to other scientific concepts. The site provides an overview of the manner the concept of evolution has been tested. This information can help dispel the myths that are 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 become more suitable to their environment. This is due to natural selection, which occurs when organisms that are more adaptable traits are more likely survive and reproduce than those with less adapted characteristics.

Common ancestor: 에볼루션 룰렛 무료체험 (click this) The most recent common ancestor of two or more distinct species. By studying the DNA of these species, it is possible to determine the common ancestor.

Deoxyribonucleic acid: A massive biological molecule that contains information required for cell replication. The information is contained in a sequence of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the cause of new genetic information within cells.

Coevolution is the relationship between two species in which the evolutionary changes of one species are influenced evolutionary changes of the other. Coevolution can be seen in the interactions between predator and prey, 에볼루션사이트 or parasites and hosts.

Origins

Species (groups that can crossbreed) develop by a series of natural variations in the traits of their offspring. These changes are caused by a variety of causes that include natural selection, genetic drift, and gene pool mixing. The evolution of a new species can take thousands of years, 에볼루션 바카라 무료 and the process could be slowed down or accelerated due to environmental conditions, such as climate change or competition for food or habitat.

The Evolution site tracks the development of a variety of groups of animals and plants over time with a focus on the key changes that took place in each group's history. It also examines the evolution of humans, which is a topic that is particularly important to students.

Darwin's Origin was published in 1859, when only a handful of antediluvian fossils of humans were discovered. The most famous among them was the skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be 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.

While the site focuses on biology, it contains a wealth of information about geology as well as paleontology. The Web site has numerous aspects that are quite impressive, such as a timeline of how geological and climate conditions have changed over the course of time. It also features maps that show the locations of fossil groups.

The site is a companion for the PBS television series, but it can also be used as a resource for teachers and students. The site is very well organized and provides clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. In particular there are hyperlinks to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has resulted in a variety of animals, plants, and insects. Paleobiology is the study of these creatures within their natural environment and has a number of advantages over the current observational and experimental methods for analyzing evolutionary processes. Paleobiology is able to study not just the processes and events that occur regularly or over time but also the distribution and frequency of different species of animals in space throughout geological time.

The website is divided into different routes that can be taken to learn about evolution. One of the paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also reveals common misconceptions about evolution as well as the history of evolutionary thought.

Each of the other sections of the Evolution site is equally developed, with materials that can be used to support a range of curriculum levels and pedagogical styles. The site includes a variety of interactive and multimedia content that include animations, video clips and virtual laboratories, in addition to its general textual content. The breadcrumb-like structure of the content helps with navigation and orientation on the vast web site.

For example the page "Coral Reef Connections" provides an overview of coral relationships and their interactions with other organisms. Then, it concentrates on a specific clam that is able to communicate with its neighbours and respond to changes in water conditions at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages, offers a great introduction to the many areas of evolutionary biology. The information also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis which is a key tool for understanding the evolution of changes.

Evolutionary Theory

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

One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that provides the depth and breadth 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 move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely linked to the world of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page highlighting John Endler's experiments in artificial selection with guppies in native ponds of Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized according to curriculum-based paths that parallel the learning objectives outlined in the biology standards. It includes seven short videos designed specifically for use in classrooms, and can be streamed for no cost or purchased on DVD.

A number of important questions remain at the heart of evolutionary biology, including what causes evolution to occur and the speed at which it occurs. This is particularly true for human evolution, which has made it difficult to reconcile the idea that the physical characteristics of humans derived from apes, and the religious beliefs that hold that humans are unique among living things and holds a an exclusive place in the creation, with soul.

In addition, there are a number of ways that evolution can be triggered, with natural selection being the most popular theory. Scientists also study other kinds such as mutation, genetic drift and sexual selection.

Although many scientific fields of study are in conflict with literal interpretations found in religious texts, evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, while others haven't.
