Evolution Site - Teaching About Evolution

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

This site, a companion to the PBS program, provides teachers with materials that promote evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

It's not easy to teach evolution well. Non-scientists often misunderstand the subject and some scientists use a definition which confuses it. This is particularly true when discussing the nature of the words themselves.

It is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful manner. The website is a companion to the show which first aired in 2001, but also functions as an independent resource. The material is presented in a nested fashion that aids navigation and orientation.

The site defines terms such as common ancestor and the gradual process. These terms help to frame the nature of evolution and its relation to other concepts in science. The site then offers an overview of how the concept of evolution has been researched and confirmed. This information will help to dispel the myths created by creationists.

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

Adaptation: The tendency of hereditary traits to become more adaptable to a specific environment. This is due to natural selection, which happens when organisms that have better-adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.

Common ancestor (also known as common ancestor): 에볼루션 바카라 체험 The most recent ancestral ancestor shared by two or more species. By studying the DNA of these species it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A huge biological molecular containing the necessary information for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, 에볼루션 슬롯게임 referred to as chromosomes. Mutations are the source of new genetic information in cells.

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

Origins

Species (groups of individuals who can interbreed) develop through natural changes in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of a new species could take thousands of years, and the process can be slowed down or speeded up by environmental factors like climate change or competition for food or habitat.

The Evolution site tracks the development of a number of different species of plants and animals over time and focuses on the most significant changes that took place in the evolution of each group's history. It also focuses on the evolutionary origin of humans, a topic that is especially 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 associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, a year before the first edition of the Origin was published, 에볼루션 슬롯게임 it is extremely unlikely that Darwin had seen or heard of it.

The site is primarily a biology site however it also includes lots of information about paleontology and geology. The most impressive features on the site are a timeline of events that illustrate the way in which climatic and geological conditions have changed over time, as well as an interactive map of the distribution of a few fossil groups that are featured on the site.

While the site is a companion piece to a PBS television show, it also stands on its own as a valuable resource for teachers and students. The site is well-organized and offers clear links to the introduction content of Understanding Evolution (developed under the National Science Foundation's support) and the more specific features of the museum's website. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are also links to John Endler's experiments with guppies. They illustrate 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 geographical context and offers numerous advantages over the current observational and experimental methods of examining evolutionary phenomena. Paleobiology focuses on not only processes and events that take place regularly or over time but also the relative abundance and distribution of different groups of animals across geological time.

The Web site is divided into various ways to learn about evolution that include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence that supports the theory of evolution. The path also examines myths about evolution, and also the history of evolutionary thought.

Each of the main sections of the Evolution website is equally well-designed, with materials that support a variety levels of curriculum and teaching methods. In addition to general textual content, the site also has a wide range of interactive and multimedia resources like videos, animations and virtual labs. The breadcrumb-like arrangement of the content helps with navigation and 바카라 에볼루션 orientation on the massive Web site.

The page "Coral Reef Connections", for example, provides a comprehensive overview of the coral's relationships, their interaction with other organisms and then zooms in to a single clam, which is able communicate with its neighbors and react to changes in the conditions of the water at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, provides an excellent introduction to a variety of topics in evolutionary biology. The material includes an overview of the role of natural selectivity and 에볼루션 무료체험 the concept of phylogenetics as a key method for understanding the evolution of changes.

Evolutionary Theory

For 에볼루션 슬롯게임 biology students, evolution is a key thread that binds all branches of the field. A rich collection supports teaching evolution across the disciplines of life sciences.

One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web site that provides depth as well as wide range 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 large Web site more closely tied to the world of research science. For instance, an animation introducing the idea of genetic inheritance connects to a page highlighting John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

Another useful resource is the Evolution Library on this Web site, which contains an extensive collection of multimedia assets connected 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 short videos that are designed for use in classrooms. These can be streamed or purchased as DVDs.

Evolutionary biology is still an area of study that poses many important questions to answer, such as what causes evolution and how quickly it takes place. This is particularly relevant in the case of human evolution where it was a challenge to reconcile religious beliefs that humanity has a unique position in the universe and a soul, with the notion that our physical traits originated from apes.

There are a myriad of other ways evolution could occur, with natural selection as the most well-known theory. Scientists also study other kinds such as mutation, genetic drift, and sexual selection.

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