This Is The Complete Guide To Evolution Site

Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, misconceptions persist about evolution. People who have taken in popular science myths often assume that biologists are saying they don't believe in evolution.

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

Definitions

It's not easy to effectively teach evolution. Non-scientists often misunderstand the subject, and some scientists even use a definition that confuses it. This is especially applicable to discussions on the meaning of the word itself.

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 manner. It is an accompaniment to the 2001 series, but it is also a resource on its own. The information is presented in a structured way that makes it easy to navigate and comprehend.

The site defines terms like common ancestor, the gradual process and adaptation. These terms help define the nature and significance of evolution with other scientific concepts. The website provides a summary of the manner that evolution has been tested. This information can help dispel the myths that are created by the creationists.

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

The process of adaptation is the tendency of heritable traits to become more suitable to their environment. This is a result of natural selection. It occurs when organisms that are more adaptable traits are more likely survive and reproduce than those with less adapted characteristics.

Common ancestor (also called common ancestor) The most recent ancestor that is shared by two or more species. By analyzing the DNA from these species it is possible to determine the common ancestor.

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

Coevolution is a relationship between two species in which the evolution of one species influence evolutionary changes of the other. Examples of coevolution are the interactions between predator and prey, or parasite and host.

Origins

Species (groups that can interbreed) change through a series natural changes in the traits of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift, and mixing of the gene pool. The development of a new species could take thousands of years and the process could be slowed or increased due to environmental conditions, such as climate change or competition for food or habitat.

The Evolution site tracks the evolution of various groups of animals and plants over time and focuses on the most significant transitions that occurred in the history of each group. It also examines the evolution of humans as a subject that is particularly important for students.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of human beings had been discovered. One of them was the infamous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was first published in 1858, one year after the first edition of The Origin. Origin.

The site is primarily a biology site, but it also contains a lot of information on geology and paleontology. One of the most appealing features on the site are a set of timelines that illustrate the way in which climatic and geological conditions changed over time, and an interactive map of the distribution of a few fossil groups listed on the site.

While the site is a companion piece to the PBS television show, it also stands on its own as a great source for teachers and students. The site is well-organized and has clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated components of the museum's 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 hyperlinks to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in many species of animals, plants and insects. Paleobiology is the study of these creatures within their natural environment and has a number of advantages over modern observational and experimental methods in its exploration of evolutionary phenomena. In  에볼루션 무료 바카라  to studying processes and events that take place regularly or over a lengthy period of time, paleobiology allows to analyze the relative abundance of different kinds of organisms as well as their distribution throughout the geological time.

The website is divided into several options to study the subject of evolution. One of these paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thought.

Each of the other major sections of the Evolution site is equally created, with resources that can be used to support a range of curriculum levels and pedagogical styles. The site includes a variety of interactive and multimedia content, including animations, video clips and virtual labs, in addition to its general textual content. The breadcrumb-like organization of the content aids in navigation and orientation on the vast website.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and interactions with other organisms and zooms in to one clam that is able to communicate with its neighbours and respond to changes in the conditions of the water 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 content includes a discussion on the role of natural selectivity and the concept of phylogenetics, an important tool for understanding evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A wide range of resources supports teaching about evolution across all life sciences.

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth and broadness in terms of educational resources. The site has a variety of interactive learning modules. It also features an "bread crumb structure" that allows students to move away from the cartoon style that is used in Understanding Evolution and onto elements of this vast website that are closely related to the fields of research science. An animation that introduces 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 has a huge multimedia library of resources that are associated to evolution. The content is organized according to curricula-based paths that correspond to the learning objectives set out in the biology standards. It contains seven videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD.

Many important questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it happens. This is especially true for humans' evolution which was a challenge to reconcile religious beliefs that humans have a distinct place in creation and a soul with the notion that our physical traits originated from the apes.

There are a variety of other ways in which evolution can occur, with natural selection as the most widely accepted theory. However, scientists also study other types of evolution such as genetic drift, mutation, and sexual selection, among others.

While many scientific fields of inquiry conflict with literal interpretations of religious texts, evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, other religions aren't.
