Evolution Site - Teaching About Evolution

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

This rich website - companion to the PBS series It provides teachers with materials that support evolution education and avoid the kinds of misconceptions that make it difficult to understand. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It's not easy to properly teach evolution. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. This is particularly true when discussing the definition of the words.

Therefore, it is important to define terms used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient manner. The site serves as a companion for the 2001 series, and also a resource of its own. The material is presented in a nested manner which aids navigation and orientation.

The site defines terms like common ancestor, the gradual process and adaptation. These terms help frame the nature of evolution as well as its relation to other concepts in science. The site then offers an overview of how the concept of evolution has been tested and validated. This information can help dispel the myths created by creationists.

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

Adaptation: The tendency for 에볼루션 바카라 체험 heritable characteristics to become more adaptable to a specific environment. This is the result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adapted traits to survive and reproduce.

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

Deoxyribonucleic acid: A large biological molecule that holds the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are the source of new genetic information within cells.

Coevolution is the relationship between two species where evolutionary changes of one species are influenced by evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey or parasite and host.

Origins

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

The Evolution site tracks through time the evolution of various animal and plant groups and focuses on major changes in each group's history. It also examines the evolutionary origin of humans and humans, a subject that is particularly important for students to comprehend.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was published in 1858, which was a year after the first edition of The Origin. Origin.

The site is primarily a biology site however it also includes many details on geology and paleontology. One of the most appealing features of the Web site are a set of timelines which show how climatic and geological conditions have changed over time and a map of the geographical distribution of some fossil groups that are featured on the site.

The site is a companion for a PBS television series, but it could also be used as an educational source for teachers and students. The site is very well-organized and has clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated components of the museum's Web site. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular, there are links to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to a variety of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment offers many advantages over modern observational or 에볼루션 바카라 체험 research methods of studying evolutionary processes. Paleobiology can examine not only processes and events that happen regularly or 에볼루션 over time, but also the relative abundance and distribution of various animal groups across geological time.

The site is divided into several optional paths to learning evolution that include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence supporting the theory of evolution. The path also reveals common misconceptions about evolution as well as the evolution of thought.

Each of the main sections of the Evolution website is equally well-designed, with materials that support a variety curriculum levels and teaching styles. In addition to general textual content, the site also has a wide range of multimedia and interactive content, such as video clips, animations, and virtual labs. The breadcrumb-like organization of the content assists with navigation and orientation on the large website.

For instance the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interactions with other organisms. Then, it zooms in on a single clam that can communicate with its neighbors and react to changes in water conditions at the level of the reef. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a broad spectrum of topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis, which is a key tool for 에볼루션 바카라사이트 understanding the evolution of changes.

Evolutionary Theory

Evolution is an underlying thread that connects all branches of biology. A wide selection of resources helps teachers teach evolution across all disciplines of life sciences.

One resource, 에볼루션 바카라 무료체험 the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that provides the depth and the broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also features a nested "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely tied to the field of research science. For example an animation that introduces the concept of genetic inheritance links to a page that focuses on John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of materials that deal with evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives set out in the biology standards. It includes seven short videos specifically intended for use in the classroom. They can be viewed online or purchased as DVDs.

A number of important questions remain at the heart of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is especially true for human evolution, which has made it difficult to reconcile the notion that the physical traits of humans were derived from apes with religious beliefs that hold that humanity is unique among living things and holds a an exclusive place in the creation with soul.

Additionally, there are a number of ways in which evolution could occur, with natural selection being the most widely accepted theory. However, scientists also study other types of evolution such as mutation, genetic drift and sexual selection, among others.

While many scientific fields of inquiry have a conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
