Evolution Site - Teaching About Evolution

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

This rich Web site, which is a complement to the PBS program offers teachers resources that support the evolution of education, while avoiding the kinds of misconceptions that undermine it. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to effectively teach evolution. It is often misunderstood by non-scientists and even some scientists have been guilty of using definitions that confuse the issue. This is particularly relevant when it comes to the nature of the words themselves.

Therefore, it is important to define terms used in evolutionary biology. Understanding Evolution's website does this in a straightforward and useful way. The site serves as an accompanying site for the 2001 series, and it is also a resource on its own. The material is presented in a nested manner that aids navigation and orientation.

The site defines terms like common ancestor, gradual process and so on. These terms help frame the nature of evolution as well as its relation to other concepts in science. The site provides an overview of the manner in which evolution has been tested. This information can help dispel myths created by creationists.

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

The process of adaptation is the tendency of hereditary traits to become more suited to the environment. This is due to natural selection, which occurs when organisms that have better adapted traits are more likely survive and reproduce than those with less adaptable traits.

Common ancestor (also called common ancestor) The most recent ancestor that is shared by two or more species. By analyzing DNA from these species it is possible to determine the common ancestor.

Deoxyribonucleic acid: 에볼루션바카라 A large biological molecule that contains information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution are the interactions between predator and prey, or the parasite and the host.

Origins

Species (groups of individuals who can interbreed) change through a series of natural changes in the traits of their offspring. The causes of these changes are many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, like changes in the climate or competition for food resources 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 history of each group. It also explores the evolutionary history of humans, a topic that is especially important for students to comprehend.

Darwin's Origin was published in 1859, 무료에볼루션 무료체험 (visit this link) when only a few antediluvian fossils of human beings had been discovered. The famous skullcap, with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, a year following the initial edition of The Origin.

The site is mostly an online biology resource, but it also contains lots of information about paleontology and geology. The site offers numerous features that are especially impressive, such as an overview of how geological and climate conditions have changed over the course of time. It also features an interactive map that shows the location of fossil groups.

Although the site is a companion piece to the PBS television show but it also stands on its own as a valuable source for teachers and students. The site is well-organized and provides clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features of the museum website. These hyperlinks make it easy to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. In particular there are hyperlinks to John Endler's research with Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures within their geographical context and offers a number of advantages over the modern observational and research methods for analyzing evolutionary processes. In addition to exploring processes and events that occur regularly or over a lengthy period of time, paleobiology is able to examine the relative abundance of different kinds of organisms as well as their distribution across geological time.

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

Each of the main sections on the Evolution website is equally well-developed, with materials that can be used to support a variety of educational levels and teaching styles. The site has a range of multimedia and interactive resources which include video clips, animations and virtual labs, in addition to its general textual content. The breadcrumb-like organization of the content helps with navigation and orientation on the massive website.

For example, the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interaction with other organisms. Then, it narrows down to a single clam that can communicate with its neighbors and respond to changes in the water conditions that take place at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages gives a good introduction to many topics in evolutionary biology. The content also includes an explanation of the importance of natural selection and the concept of phylogenetics analysis which is a crucial tool to understand evolutionary change.

Evolutionary Theory

For biology students, evolution is a key thread that binds all the branches of the field. A vast collection of resources can help teachers teach about evolution across the life sciences.

One resource, the companion to PBS's television series Understanding Evolution is an excellent example of a Web site that provides depth and breadth in terms of its educational resources. The site has a variety 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 large Web site more closely linked to the field of research science. Animation that introduces the concept of genetics links to a page that highlights John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized into courses that are based on curriculum and 에볼루션 사이트 follow the learning goals established in the biology standards. It contains seven short videos intended for use in the classroom. They are available to stream or purchase as DVDs.

Many important questions remain at the heart of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is especially relevant to human evolution, where it has been difficult to reconcile that the physical traits of humans derived from apes with religious beliefs that claim that humanity is unique in the universe and has an enviable place in creation, with a soul.

There are a variety of other ways evolution can occur, with natural selection as the most well-known theory. However scientists also study different kinds of evolution, such as genetic drift, mutation, and 바카라 에볼루션 sexual selection, among others.

Many fields of inquiry are in conflict with literal interpretations of religious texts, evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the theories of evolution, other religions haven't.
