Evolution Site - Teaching About Evolution

Depositphotos_218520288_XL-scaled.jpgDespite the best efforts by biology educators, there are still a lot of misconceptions regarding evolution. Pop science nonsense has led people to think that biologists don't believe in evolution.

This rich Web site - companion to the PBS series - provides teachers with materials that promote evolution education and avoid the kinds of misinformation that can make it difficult to understand. It's laid out in the "bread crumb" format to aid in navigation and orientation.

Definitions

Evolution is a complicated and challenging subject to teach well. People who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. This is especially applicable to discussions about the nature of the word.

It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site is a companion to the show which first aired in 2001, but it can also function as an independent resource. The information is presented in an organized manner that makes it simpler to navigate and understand.

The site defines terms such as common ancestor and gradual process. These terms help to define the nature of evolution and its relation to other scientific concepts. The website provides a summary of the way in which evolution has been examined. This information can be used to dispel misconceptions that have been created by creationists.

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

The process of adaptation is the tendency of heritable traits to be better suited to an environment. This is the result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adapted traits to survive and reproduce.

Common ancestor 에볼루션 바카라 (also called common ancestor) is the most recent ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of the species.

Deoxyribonucleic Acid: A large biological molecular containing the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution is a relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution include the interactions between predator and prey or host and parasite.

Origins

Species (groups that can interbreed) develop through a series natural changes in their offspring's traits. These changes are caused by a variety of causes such as natural selection, genetic drift and gene pool mixing. The evolution of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food resources and habitat can slow or speed up the process.

The Evolution site tracks the development of a number of different species of plants and animals over time and focuses on the most significant changes that took place in the evolution of each group's history. It also examines the evolutionary history of humans, a topic that is crucial for students to understand.

Darwin's Origin was published in 1859, when only a handful of antediluvian fossils of humans were discovered. The famous skullcap, along with the bones associated with it, was 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, 에볼루션 블랙잭 a year before the first edition of the Origin was published, it's very unlikely that Darwin had seen or heard of it.

The site is mostly an online biology resource however it also includes a lot of information on paleontology and geology. One of the most appealing features of the Web site are a set of timelines that illustrate how climatic and geological conditions have changed over time as well as a map of the geographical distribution of some of the fossil groups featured on the site.

The site is a companion for the PBS television series, 에볼루션 바카라 but it could be used as a source for teachers and students. The site is well-organized, and provides easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features of the museum's website. These hyperlinks make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular there are hyperlinks to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures in their geological context, has many advantages over the current observational or 에볼루션 사이트 바카라 무료 (Ramsey-hvass-3.Technetbloggers.De) experimental methods for studying evolutionary processes. Paleobiology is able to study not only processes and events that take place 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 website is divided into several optional ways to learn about evolution, including "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence to support the theory of evolution. The course also focuses on misconceptions regarding evolution, and the background of evolutionary thinking.

Each of the other major sections of the Evolution site is equally well developed, with materials that can support a variety of educational levels and pedagogical styles. The site offers a wide array of multimedia and interactive resources, including animations, video clips and virtual laboratories in addition to general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the large Web site.

For instance the page "Coral Reef Connections" gives a brief overview of coral relationships and their interaction with other organisms. It then concentrates on a specific clam that is able to communicate with its neighbours and respond to changes in the water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to a variety of topics in evolutionary biology. The content also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis, which is a crucial tool in understanding evolutionary change.

Evolutionary Theory

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

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that provides depth as well as broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also features a nested "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. An animation that introduces the concept of genetics links to a page highlighting John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.

Another helpful resource is the Evolution Library on this site, which has an extensive multimedia library of items connected to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives set out in biology standards. It contains seven videos designed specifically for classroom use, which can be streamed for no cost or purchased on DVD.

A variety of crucial questions remain in the midst of evolutionary biology, 에볼루션 코리아 including what causes evolution to occur and how fast it happens. This is especially true for human evolution, where it has been difficult to reconcile the idea that the physical traits of humans derived from apes with religions that believe that humans are unique among living things and holds a an exclusive place in the creation, with a soul.

In addition there are a myriad of ways that evolution could be triggered and natural selection is the most popular theory. Scientists also study other types such as genetic drift and sexual selection.

Depositphotos_73724137_XL-890x664.jpgWhile many scientific fields of inquiry are in conflict with the literal interpretations of religious texts evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions haven't.
