Evolution Site - Teaching About Evolution

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

This rich Web site - companion to the PBS series offers teachers with resources that promote evolution education and avoids the kinds of misconceptions that hinder it. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to teach evolution well. Many non-scientists are unable to grasp the concept and some scientists use a definition which confuses it. This is especially relevant when discussing the nature of the words themselves.

It is essential to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. It is an accompaniment to the 2001 series, but also a resource on its own. The content is organized in a way that makes it easy to navigate and comprehend.

The site defines terms such as common ancestor, 에볼루션 블랙잭 gradual process and so on. These terms help to frame the nature of evolution as well as its relation to other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and validated. This information can help dispel myths created by creationists.

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

Adaptation is the tendency of heritable traits to become more suitable to their environment. This is due to natural selection, which occurs when organisms that are better-adapted traits are more likely to survive and reproduce than those with less adaptable traits.

Common ancestor: The latest common ancestor of two or more species. The common ancestor can be identified by studying the DNA of these species.

Deoxyribonucleic acid: A massive biological molecule that holds the information needed for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, called chromosomes. Mutations are the source of new genetic information in cells.

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

Origins

Species (groups that can interbreed) change through a series of natural changes in the traits of their offspring. These changes are caused by a variety of factors such as natural selection, genetic drift, and mixing of gene pools. The evolution of new species could take thousands of years. Environmental conditions, like climate changes or competition for food and habitat can impede or accelerate the process.

The Evolution site traces the emergence of a variety of animal and plant groups through time and focuses on the most significant shifts that occurred throughout each group's history. It also focuses on 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 recognized as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year before the first edition of the Origin appeared, it is highly unlikely that Darwin had seen or 에볼루션 게이밍 heard of it.

While the site focuses on biology, it also contains a wealth of information on geology and paleontology. The most impressive features of the Web site are a series of timelines that illustrate how geological and climatic conditions have changed over time, and a map of the distribution of some fossil groups listed on the site.

The site is a companion for the PBS TV series but it could be used as a source for teachers and students. The site is extremely well-organized and offers clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These links facilitate the transition from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in many species of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment and has a number of advantages over the current observational and experimental methods of examining evolutionary phenomena. In addition to studying processes and events that occur regularly or over a lengthy period of time, paleobiology allows to examine the relative abundance of various groups of organisms and their distribution in space over geological time.

The website is divided into various paths that can be chosen to study the subject of evolution. One of the paths, "Evolution 101," walks the reader 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 other major sections of the Evolution site is similarly created, with resources that can be used to support a range of educational levels and pedagogical styles. The site has a range of multimedia and interactive resources that include animations, video clips and virtual laboratories as well as general textual content. The breadcrumb-like arrangement of the content helps with navigation and orientation on the vast Web site.

The page "Coral Reef Connections" For instance, it provides a comprehensive overview of coral relationships, their interaction with other organisms and 무료 에볼루션 에볼루션 카지노 사이트 (by 120.zsluoping.cn) then zooms in on one clam, which can communicate with its neighbours and respond to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and multimedia pages provides an excellent introduction to the many areas of evolutionary biology. The content includes an explanation of the role of natural selectivity and the concept of phylogenetics, an important method for 무료에볼루션 understanding the evolution of changes.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A vast collection of resources supports teaching 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 the depth and the breadth in terms of its educational resources. The site has a wide array 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 tied to the world of research science. For example an animation that introduces the notion of genetic inheritance leads to a page highlighting John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.

Another resource that is worth mentioning is the Evolution Library on this web site, which contains an extensive collection of multimedia items that are related to evolution. The content is organized in curricula-based paths that correspond to the learning objectives set out in the standards for biology. 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 at the heart of evolutionary biology, such as the factors that trigger evolution and how fast it occurs. This is particularly relevant for humans' evolution which was a challenge to reconcile religious beliefs that held that humanity has a unique position in the universe and a soul with the notion that human beings have innate physical traits originated from apes.

There are also a number of other ways in which evolution could occur, with natural selection as the most popular theory. Scientists also study different types such as mutation, genetic drift, and sexual selection.

While many fields of scientific study have a conflict with literal interpretations found in religious texts, the concept of evolution biology has been a source of intense controversy and opposition from religious fundamentalists. Certain religions have embraced their beliefs to evolution while others haven't.
