Evolution Site - Teaching About Evolution

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

This rich Web site, which is a companion to the PBS program offers teachers resources which support evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's organized in the "bread crumb" format to make navigation and orientation easier.

Definitions

Evolution is a complex and challenging subject to teach well. Non-scientists often misunderstand the subject and some scientists use a definition which confuses it. This is especially applicable to discussions on the definition of the word itself.

It is therefore important 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. The website is a companion to the show that premiered in 2001, but it is also an independent resource. The material is organized in a manner that makes it simpler to navigate and comprehend.

The site defines terms such as common ancestor, gradual process and so on. These terms help to define the nature of evolution as well as its relation to other scientific concepts. The site gives a comprehensive overview of the way the concept of evolution has been tested. This information will help to dispel the myths created by creationists.

It is also possible to get a glossary of terms that are 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 with more adaptable characteristics are more likely than those with less adapted characteristics to survive and reproduce.

Common ancestor: The latest common ancestor of two or more species. By analyzing the DNA from these species it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A large biological molecular that holds the information required for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are the source of new genetic information within cells.

Coevolution: A relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey, or host and parasite.

Origins

Species (groups of individuals who can interbreed) develop through a series of natural changes in the traits of their offspring. The causes of these changes are numerous factors, 에볼루션카지노 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 can be slowed or increased by environmental conditions such as climate change or the competition for food or habitat.

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 each group's history. It also explores the evolutionary history of humans which is particularly important for students to comprehend.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The famous skullcap, along with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just a year before the first edition of the Origin was published, it is highly unlikely that Darwin had seen or heard of it.

While the site is focused on biology, it also contains a wealth of information about geology and paleontology. The site offers numerous aspects that are quite impressive, such as a timeline of how geological and climate conditions have changed over time. It also has an interactive map that shows the location of fossil groups.

The site is a companion to the PBS TV series but it could also be used as a resource by teachers and students. The site is well-organized, and 에볼루션카지노사이트 provides easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features of the museum website. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler’s experiments with guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced many species of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment offers many advantages over the current observational or experimental methods of studying evolutionary processes. Paleobiology focuses on not only the process and events that take place frequently or over time, but also the distribution and frequency of different species of animals in space over the course of geological time.

The website is divided into various options to gain knowledge about evolution. One of these paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The path also examines myths regarding evolution, and the background of evolutionary thought.

Each of the main sections on the Evolution website is equally well-developed, 에볼루션 사이트 with materials that support a variety levels of curriculum and teaching methods. The site has a range of interactive and multimedia content that include animations, video clips and virtual laboratories, in addition to its general textual content. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation within the large Web site.

The page "Coral Reef Connections", for example, gives a brief overview of the relationships between corals, their interaction with other organisms and then zooms in on one clam, which can communicate with its neighbours and respond to changes in conditions of the water at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to many topics in evolutionary biology. The information also includes a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a key method to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that runs through all branches of biology. A rich collection supports teaching evolution across all disciplines of life science.

One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that offers both the depth and breadth of its educational resources. The site has a variety of interactive learning modules. It also features 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 linked to the fields of research science. An animation that introduces the concept of genetics is linked to a page that highlights John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.

Another helpful resource is the Evolution Library on this website, which includes an extensive collection of multimedia items related to evolution. The contents are organized into courses that are based on curriculum and follow the learning objectives set out in biology standards. It includes seven short videos designed for classroom use. They can be streamed or 에볼루션 사이트 purchased as DVDs.

A number of important questions remain at the heart of evolutionary biology, such as the factors that trigger evolution and the speed at which it occurs. This is especially applicable to human evolution where it's been difficult to reconcile the idea that the physical characteristics of humans were derived from apes, and the religions that believe that humanity is unique in the universe and has an exclusive place in the creation with a soul.

There are a myriad of other ways in which evolution can take place including natural selection, which is the most popular theory. Scientists also study other types like mutation, genetic drift, and sexual selection.

While many fields of scientific inquiry are in conflict with literal interpretations of religious texts, 에볼루션 게이밍카지노사이트 [simply click the up coming website] evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, others aren't.
