Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. People who have absorbed the nonsense of pop science often believe that biologists claim they don't believe in evolution.

This rich website - companion to the PBS series offers teachers with resources that promote evolution education and help avoid the kinds of myths that undermine it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complicated and difficult subject to teach well. It is often misunderstood by non-scientists and even some scientists are guilty of using definitions that confuse the issue. This is especially true when it comes to discussions on the definition of the word itself.

As such, 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. The site is both a companion for the 2001 series, and also a resource of its own. The content is presented in a structured manner that makes it simpler to navigate and 에볼루션 코리아 understand.

The site defines terms such as common ancestor, gradual process and adaptation. These terms help define the nature of evolution and its relationship to evolution with other scientific concepts. The site gives a comprehensive overview of the ways the concept of evolution has been examined. This information can help dispel the myths created by creationists.

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

Adaptation is the process of changing heritable traits to become more suitable to their environment. This is the result of natural selection. Organisms with better-adapted characteristics are more likely than those with less adaptable traits to survive and reproduce.

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

Deoxyribonucleic acid: A large biological molecule that contains information required for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form long chains, 에볼루션 바카라 체험 also known as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be observed through the interaction between predator and prey, or parasites and hosts.

Origins

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

The Evolution site traces the emergence of a number of different animal and plant groups through time and focuses on the most significant changes that took place in each group's history. It also focuses on the evolutionary origin of humans which is especially important for students to understand.

Darwin's Origin was written in 1859, at a time when only a handful of antediluvian fossils of humans were discovered. Among them was the famous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year after the first edition of the Origin appeared, it is highly unlikely that Darwin had heard or seen of it.

While the site is focused on biology, it also contains a wealth of information on geology and paleontology. One of the most appealing features of the Web site are a timeline of events which show how geological and climatic conditions have changed over time and a map of the distribution of a few of the fossil groups featured on the site.

The site is a companion for the PBS television series, 무료에볼루션 but it could also be used as a resource for teachers and students. The site is extremely well-organized and 에볼루션 바카라 체험 has clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are links to John Endler's research with Guppies, which demonstrate the importance of 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 in their geological context and has many advantages over modern observational and experimental methods for analyzing evolutionary processes. In addition to exploring processes and events that occur frequently or over a long period of time, paleobiology is able to examine the relative abundance of various species of organisms and their distribution across the course of geological time.

The site is divided into a variety of ways to learn about evolution which include "Evolution 101," which takes the viewer on a line through the nature of science and the evidence to support the theory of evolution. The course also focuses on misconceptions about evolution, as well as the history of evolutionary thought.

Each of the other major sections of the Evolution site is equally well created, with resources that can support a variety of educational levels and pedagogical styles. In addition to the general textual content, the site offers an array of multimedia and interactive resources like videos, animations and virtual laboratories. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation on the Web site.

The page "Coral Reef Connections", for example, provides an overview of coral relationships and interactions with other organisms and is enlarged to show one clam that can communicate with its neighbors and respond to changes in conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to the broad variety of topics in evolutionary biology. The content also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is a key tool for understanding the evolution of changes.

Evolutionary Theory

For biology students, evolution is a key thread that connects all the branches of the field. A rich collection of resources helps teachers teach about evolution across all life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that provides the depth and breadth of its educational resources. The site has a variety of interactive learning modules. It also features an encased "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. For instance an animation that introduces the notion of genetic inheritance leads to a page that focuses on John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of resources that are associated with evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives outlined in the standards for biology. It contains seven videos specifically designed for use in classrooms, 에볼루션 바카라 무료체험 바카라 에볼루션 체험; 2ch-Ranking.Net, and can be streamed at no cost or purchased on DVD.

Evolutionary biology is still an area of study with a lot of important questions, such as what triggers evolution and how fast it occurs. This is particularly true for the evolution of humans, where it was difficult to reconcile religious beliefs that humans have a distinct place in the creation and a soul with the idea that innate physical traits originated from Apes.

Additionally there are a myriad of ways that evolution can be triggered and natural selection is the most widely accepted theory. Scientists also study different types such as genetic drift, and sexual selection.

While many fields of scientific study conflict with literal interpretations in religious texts, evolution biology has been a subject of intense debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
