Evolution Site - Teaching About Evolution

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

This site, which is a companion to the PBS program offers teachers resources that promote evolution education, while avoiding the kinds of misconceptions that can make it difficult to understand. It's laid out in a "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and difficult subject to teach well. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is especially true when discussing the nature of the words themselves.

It is therefore crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful manner. It is an accompanying site for the 2001 series, and also a resource on its own. The material is presented in a nested manner which aids navigation and orientation.

The site defines terms like common ancestor (or common ancestor), gradual process, and adaptation. These terms help frame the nature and relationship of evolution with other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and validated. This information can be used to dispel misconceptions that have been propagated by creationists.





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

Adaptation: The tendency of hereditary traits to become more suitable to a particular setting. This is a result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted traits to survive and reproduce.

Common ancestor (also known as common ancestor): The most recent ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of the species.

Deoxyribonucleic acid: A huge 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 influenced by evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or parasite and host.

Origins

Species (groups of individuals that can interbreed) change through 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 development of a new species could take thousands of years, and the process may be slowed down or speeded up due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site follows the emergence of various species of plants and animals with a focus on major changes within each group's past. It also explores human evolution and is a subject of particular importance to students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, a year after the publication of the first edition of The Origin. Origin.

The site is mostly an online biology resource however it also includes lots of information about geology and paleontology. The Web site has several features that are particularly impressive, such as a timeline of how geological and climate conditions have changed over the course of time. It also has an interactive map that shows the location of fossil groups.

Although the site is a companion piece to the PBS television show however, it can stand on its own as an excellent source for teachers and students. The site is well-organized, and provides clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features of the museum website. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also links to John Endler's experiments with guppies, which illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in an array of plants, animals and insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over modern observational and experimental methods in its exploration of evolutionary processes. Paleobiology can examine not just the processes and events that occur regularly or over time, but also the distribution and frequency of different groups of animals in space over the course of geological time.

The site is divided into various routes that can be taken to study the subject of evolution. One of these paths, "Evolution 101," walks the reader through the evolution of nature and the evidence of evolution. The path also examines myths regarding evolution, and also the history of evolutionary thought.

Each of the other major sections of the Evolution site is equally developed, with materials that can support a variety of curriculum levels and pedagogical styles. The site has a range of interactive and multimedia resources, including video clips, animations and virtual laboratories in addition to general textual content. 에볼루션 슬롯 is presented in a nested bread crumb fashion that aids navigation and orientation within the vast web site.

The page "Coral Reef Connections" For instance, it provides an overview of coral 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 water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a broad variety of topics in evolutionary biology. The content also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis, which is an important method to understand evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A vast collection of books helps in teaching evolution across all disciplines of life science.

One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that provides the depth and the breadth in terms of its educational resources. The site features a wealth of interactive learning modules. It also features a "bread crumb structure" that helps students move away from the cartoon style used in Understanding Evolution and onto elements of this vast website that are closely connected to the realms of research science. For instance an animation that introduces the concept of genetic inheritance links to a page that focuses on John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of assets related to evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives set out in the standards for biology. It contains seven short videos that are designed for classroom use. They can be viewed online or purchased as DVDs.

Many important questions remain at the heart of evolutionary biology, including what causes evolution to occur and how fast it happens. This is particularly relevant for the evolution of humans, where it was difficult to reconcile religious beliefs that humanity has a unique position in the universe and a soul, with the notion that our physical traits evolved from Apes.

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

Many fields of inquiry have a conflict with literal interpretations of religious texts evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolution, while others haven't.
