Evolution Site - Teaching About Evolution

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

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

Definitions

It is difficult to properly teach evolution. It is often misunderstood even by non-scientists, and even some scientists have been guilty of using definitions that confuse the issue. This is especially true when discussing the meaning of the words themselves.

Therefore, 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 clear and helpful way. The site is a companion site to the show which first aired in 2001, but can also function as an independent resource. The material is presented in a nested fashion that aids navigation and orientation.

The site defines terms such as common ancestor (or common ancestor), gradual process, and adaptation. These terms help frame the nature of evolution as well as its relationship to other scientific concepts. The site gives a comprehensive overview of the manner the concept of evolution has been tested. This information can help dispel myths created by creationists.

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

Adaptation: The tendency of heritable traits to become better suited to a particular environment. This is a result of natural selection, which happens when organisms that are more adaptable characteristics are more likely to survive and reproduce than those with less adapted traits.

Common ancestor (also called common ancestor) is the most recent ancestor 에볼루션 무료 바카라 (http://Douerdun.com) that is shared by two or more species. The common ancestor can be identified by analyzing the DNA of the species.

Deoxyribonucleic Acid: A huge biological molecular containing the necessary information for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, 바카라 에볼루션 (https://www.meetme.com/Apps/redirect/?url=https://telegra.ph/Evolution-Gamings-History-History-Of-Evolution-Gaming-12-30) called chromosomes. Mutations are the source of new genetic information in cells.

Coevolution is the relationship between two species where evolution of one species are influenced evolutionary changes of the other. Coevolution is evident in the interaction of predator and prey, or parasites and hosts.

Origins

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

The Evolution site traces through time the evolution of different groups of animals and plants with a focus on major changes in each group's past. It also examines the evolution of humans, which is a topic of particular importance to students.

Darwin's Origin was published in 1859, when just a handful of antediluvian fossils of humans had been found. The famous skullcap, along with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. Although the skullcap was not published until 1858, a year before the first edition of the Origin was published, it is very unlikely that Darwin had seen or heard of it.

While the site focuses on biology, it offers a lot of information about geology as well as paleontology. Among the best features of the Web site are a timeline of events which show the way in which climatic and geological conditions have changed over time as well as an outline of the distribution of a few fossil groups listed on the site.

The site is a companion for the PBS television series, but it could also be used as an educational resource by teachers and students. The site is well-organized and provides clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features of the museum website. 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, which illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of plants, animals and insects. Paleobiology is the study of these creatures in their geological environment is a superior method of study over the current observational or experimental methods of studying evolutionary phenomena. Paleobiology focuses on not only processes and events that take place frequently or over time, but also the relative abundance and distribution of different groups of animals in space throughout geological time.

The Web site is divided into various paths to learning evolution, including "Evolution 101," which takes the viewer on a line through the scientific process and the evidence supporting the theory of evolution. The path also explores misconceptions about evolution and also the history of evolutionary thought.

Each of the other sections of the Evolution site is equally developed, with materials that support a variety of curriculum levels and pedagogical styles. The site includes a variety of multimedia and interactive resources that include animations, video clips and virtual laboratories as well as general textual content. The breadcrumb-like arrangement of the content aids in navigation and orientation on the vast Web site.

For instance the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interactions with other organisms. Then, it zooms in on a single clam that can communicate with its neighbors and react to changes in water conditions that occur at the level of the reef. This page, as well as the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a wide variety of topics in evolutionary biology. The content also includes an overview of the significance of natural selectivity and the concept of phylogenetics analysis as a key method for understanding the evolution of changes.

Evolutionary Theory

Evolution is an underlying thread that connects all branches of biology. A rich collection supports teaching evolution across the disciplines of life science.

One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and a variety of educational resources. The site has a wide array of interactive learning modules. It also features a "bread crumb structure" that allows students to move away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely related to the realms of research science. For example, 에볼루션 바카라 무료체험사이트 - dokuwiki.Stream - an animation introducing the notion of genetic inheritance leads to a page that focuses on John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized according to curriculum-based paths that parallel the learning goals established in the standards for biology. It includes seven short videos designed specifically for use in the classroom, and can be streamed for no cost or purchased on DVD.

A variety of crucial questions remain at the core of evolutionary biology, such as what triggers evolution and how fast it happens. This is especially true for the evolution of humans which was a challenge to reconcile religious beliefs that humans have a distinct position in the universe and a soul with the notion that our physical traits were derived from Apes.

There are also a number of other ways in which evolution can take place, with natural selection as the most widely accepted theory. Scientists also study other kinds like mutation, genetic drift and sexual selection.

While many scientific fields of inquiry are in conflict with literal interpretations of religious texts Evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, other religions have not.
