Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution persist. People who have absorbed pop science nonsense often assume that biologists don't believe in evolution.

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

Definitions

Evolution is a complicated and challenging subject to teach well. Non-scientists often misunderstand the subject, and some scientists even use a definition which confuses it. This is especially true when it comes to debates about the definition of the word itself.

Therefore, it is important to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. It is an accompaniment to the 2001 series, but it is also a resource on its own. The content is presented in a way that aids navigation and 에볼루션 코리아 orientation.

The site defines terms like common ancestor and gradual process. These terms help to define the nature of evolution as well as its relationship to other concepts in science. The site provides an overview of the manner that evolution has been tested. This information will help to dispel the myths that are created by the creationists.

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

The process of adaptation is the tendency of heritable traits to become better suited to an environment. This is a result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted traits to survive and reproduce.

Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified by analyzing the DNA of those species.

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

Coevolution is a relation between two species in which the evolutionary changes of one species are influenced evolutionary changes of the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts.

Origins

Species (groups of individuals that can interbreed) change through an array of natural changes in the characteristics of their offspring. The changes can be caused by a variety such as natural selection, genetic drift, and mixing of genes. The development of new species can take thousands of years. Environmental circumstances, such as climate change or competition for food and habitat, can slow or accelerate the process.

The Evolution site traces the emergence of a number of different species of plants and animals over time with a focus on the key changes that took place in the evolution of each group's history. 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 few antediluvian fossils of humans were discovered. The skullcap that is famous, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap when it was published in 1858, which was a year after the first edition of The Origin.

The site is primarily an online biology resource however it also includes many details on paleontology and geology. One of the most appealing features of the website are a timeline of events which show how climatic and geological conditions have changed over time as well as a map of the distribution of a few fossil groups that are featured on the site.

While the site is a companion piece to a PBS television show but it also stands on its own as a great source for teachers and students. The site is well-organized, and provides clear links to the introductory content of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features of the museum's website. These hyperlinks help users move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also links to John Endler's experiments with guppies that illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology is the study of these creatures within their geological context is a superior method of study over modern observational or research methods for exploring evolutionary phenomena. Paleobiology is able to study not just the processes and 에볼루션 카지노 사이트 무료체험 (yanyiku.Cn) events that take place frequently or over time, but also the distribution and frequency of various animal groups in space over the course of the geological time.

The site is divided up into different paths that can be chosen to learn about evolution. One of the paths, "Evolution 101," guides the user through the nature and evidence of evolution. The path also reveals common misconceptions about evolution as well as the evolution of thought.

Each of the main sections on the Evolution website is equally well-designed, with materials that support a variety levels of curriculum and teaching methods. In addition to the standard textual content, the site also has an extensive selection of multimedia and interactive resources including videos, animations, and virtual labs. The breadcrumb-like organization of the content aids in navigation and orientation on the vast website.

For example the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interactions with other organisms. Then, it narrows down to a single clam that can communicate with its neighbors and react to changes in the water conditions that occur at the level of the reef. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The content also includes an explanation of the role of natural selection and the concept of phylogenetic analysis which is a key tool for 에볼루션 무료체험 understanding the evolution of changes.

Evolutionary Theory

For biology students evolution is a crucial thread that weaves together all branches of the field. A wide selection of resources helps teachers teach evolution across all disciplines of life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides the depth and breadth of its educational resources. The site offers a range of interactive learning modules. It also has a "bread crumb structure" that helps students move away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely connected to the fields of research science. For example an animation that introduces the notion of genetic inheritance leads to a page that highlights John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

Another useful resource is the Evolution Library on this site, which contains an extensive multimedia library of resources connected to evolution. The content is organized according to curriculum-based paths that parallel the learning goals established in the biology standards. It includes seven short videos that are designed for use in classrooms. They are available to stream or purchase as DVDs.

Evolutionary biology is still an area of study that has many important questions, such as the causes of evolution and how fast it takes place. This is particularly relevant in the case of human evolution, where it was difficult to reconcile religious beliefs that humanity has a unique place in creation and a soul with the idea that innate 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 well-known theory. Scientists also study other kinds such as mutation, genetic drift, and sexual selection.

Depositphotos_274035516_XL-scaled.jpgWhile many fields of scientific study are in conflict with the literal interpretations of religious texts, evolution biology has been a source of intense debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, others haven't.
