Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution remain. People who have been exposed to the nonsense of pop science often believe that biologists claim they do not believe in evolution.

This site, a companion to the PBS program offers teachers resources that support the evolution of education while avoiding the types of misconceptions that hinder it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

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

As such, it is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site is a companion to the show that premiered in 2001, but it is also an independent resource. The material is presented in a structured manner that makes it simpler to navigate and understand.

The site defines terms like common ancestor, gradual process and so on. These terms help frame the nature of evolution as well as its relationship to other concepts in science. The site then offers an overview of how the concept of evolution has been researched and validated. This information can help dispel the myths created by creationists.

You can also access a glossary that includes terms used in evolutionary biology. These terms include:

Adaptation: The tendency for hereditary traits to become more adaptable to a specific environment. This is a result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adaptable traits to reproduce and survive.

Common ancestor (also known as common ancestor) is the most recent ancestor shared by two or more species. By studying the DNA of these species, it is possible to determine the common ancestor.

Deoxyribonucleic acid: A huge biological molecule that holds the information required for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

Coevolution is the relationship between two species, where the evolution of one species influence evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey, or host and 에볼루션 슬롯게임 parasite.

Origins

Species (groups of individuals that can interbreed) evolve through natural changes in the characteristics of their offspring. The changes can be triggered by a variety of factors that include natural selection, genetic drift and mixing of gene pools. The development of new species can take thousands of years. Environmental conditions, like climate changes or competition for food and habitat can slow or speed up the process.

The Evolution site tracks the evolution of a number of different animal and plant groups through time with a focus on the key transitions that occurred in the evolution of each group's history. It also examines the evolution of humans as a subject that is particularly important for students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year after the first edition of the Origin was published, it is highly unlikely that Darwin had heard or seen of it.

The site is mostly an online biology resource, but it also contains many details on geology and paleontology. The most impressive features on the site are a timeline of events that show how geological and climatic conditions have changed over time, and an interactive map of the distribution of a few fossil groups that are featured on the site.

The site is a companion to a PBS TV series but it could also be used as an educational resource for teachers and students. The site is well-organized and provides easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized features of the museum website. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. In particular there are hyperlinks to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in an array of animals, plants and insects. Paleobiology, the study of these creatures in their natural environment offers many advantages over the current observational or experimental methods for exploring evolutionary phenomena. Paleobiology is able to study not only processes and 에볼루션바카라 - covington-santana.technetbloggers.De, events that happen frequently or over time, but also the relative abundance and distribution of various animal groups in space throughout the geological time.

The website is divided into different paths that can be chosen to learn about evolution. One of the paths, "Evolution 101," walks the reader through the evolution of nature and the evidence of evolution. The path also explores common misconceptions about evolution as well as the evolution of thought.

Each of the other sections of the Evolution site is equally well created, with resources that support a variety of educational levels and pedagogical styles. In addition to the standard textual content, the site features an array of multimedia and interactive content like video clips, animations, and virtual laboratories. The breadcrumb-like arrangement of the content helps with navigation and orientation on the large web site.

For example, the page "Coral Reef Connections" provides an overview of coral relationships and their interactions with other organisms, then narrows down to a single clam that can communicate with its neighbors and respond to changes in the water conditions at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to many topics in evolutionary biology. The content includes an overview of the significance of natural selectivity and the concept of phylogenetics which is a crucial method for understanding the evolution of change.

Evolutionary Theory

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

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 features a wide range of interactive learning modules. It also features an encased "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the world of research science. For example an animation that introduces the concept of genetic inheritance links to a page highlighting John Endler's experiments in artificial selection with guppies in native ponds of Trinidad.

Another helpful resource is the Evolution Library on this web website, which includes an extensive collection of multimedia items that are related to evolution. The content is organized into curricula-based pathways that correspond to the learning goals established in biology standards. It contains seven short videos that are intended for use in the classroom. They can be streamed or purchased as DVDs.

Many important questions remain at the core of evolutionary biology, including what causes evolution to occur and how fast it occurs. This is especially true for humans' evolution, where it was difficult to reconcile religious beliefs that humanity has a special place in the creation and a soul with the idea that innate physical traits were derived from Apes.

Additionally there are a myriad of ways that evolution can occur, with natural selection being the most widely accepted theory. However, scientists also study other kinds of evolution, such as mutation, genetic drift, and sexual selection, 에볼루션 블랙잭 among others.

While many fields of scientific study conflict with the literal interpretations of religious texts, evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the ideas of evolution, other religions haven't.
