Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution remain. Pop science fiction has led a lot of 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 misinformation that can make it difficult to understand. It's organized in the "bread crumb" format to aid in navigation and orientation.

Definitions

It's difficult to teach evolution well. People who are not scientists often have a difficult time understanding the subject, and some scientists even use a definition which confuses it. This is especially true when it comes to discussions on the nature of the word.

As such, it is essential to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The site serves as a companion for the 2001 series, and it is also a resource on its own. The material is presented in an organized manner that makes it easier to navigate and understand.

The site defines terms such as common ancestor and the gradual process. These terms help to define the nature and relationship of evolution to other concepts in science. The site then offers an overview of how the concept of evolution has been tested and confirmed. This information can be used to dispel misconceptions that have been engendered by creationists.

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

The process of adaptation is the tendency of hereditary traits to become better suited to an environment. This is the result of natural selection, which happens when organisms that are better-adapted traits are more likely survive and reproduce than those with less adapted traits.

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

Deoxyribonucleic acid: A huge biological molecule that holds the information necessary for cell replication. The information is stored in nucleotide sequences which are strung into long chains, 에볼루션 무료 바카라 referred to as chromosomes. Mutations are the source of new genetic information in cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be seen in the interactions between predator and prey, or parasite and hosts.

Origins

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

The Evolution site tracks through time the evolution of different animal and plant groups with a focus on major changes in each group's history. It also explores the evolutionary origin of humans and humans, 에볼루션 코리아 a subject that is especially important for students to comprehend.

Darwin's Origin was published in 1859, when just a handful of antediluvian fossils of humans were discovered. The skullcap that is famous, along with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just a year before the first edition of the Origin was published, 에볼루션바카라사이트 it's very unlikely that Darwin had seen or heard of it.

The site is mostly an online biology resource however, it also has lots of information about geology and paleontology. The most impressive features of the website are a set of timelines that illustrate how climatic and geological conditions have changed over time and an outline of the distribution of a few fossil groups that are featured on the site.

The site is a companion for the PBS television series, but it could also be used as a resource by teachers and students. The site is well-organized and offers clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features on the museum's website. These hyperlinks make it easy 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 led to a variety of animals, plants and insects. Paleobiology is the study of these creatures within their geological context and has numerous advantages over the current observational and experimental methods of examining evolutionary processes. Paleobiology focuses on not only the process and events that take place frequently or over time, 에볼루션 슬롯게임 but also the relative abundance and distribution of different species of animals across geological time.

The site is divided up into different routes that can be taken to gain knowledge about evolution. One of these paths, "Evolution 101," takes the viewer through the nature and evidence of evolution. The path also examines myths about evolution and the background of evolutionary thinking.

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. The site includes a variety of interactive and multimedia resources that include videos, animations, and virtual labs in addition to general textual content. The content is laid out in a nested bread crumb style that facilitates navigation and orientation on the Web site.

For example the page "Coral Reef Connections" provides an overview of coral relationships and their interactions with other organisms, then concentrates on a specific clam that is able to communicate with its neighbors and react to changes in water conditions that occur at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to the broad variety of topics in evolutionary biology. The material also provides a discussion of the role of natural selection as well as the concept of phylogenetic analysis which is a key method to understand evolutionary changes.

Evolutionary Theory

For biology students the concept of evolution is a major thread that weaves together all branches of the field. A wide selection of resources helps teachers teach evolution across all disciplines of life sciences.

One resource, the companion to PBS's television series Understanding Evolution is an excellent example of a Web site that provides depth and breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also features an "bread crumb structure" that allows students to move away from the cartoon-like style used in Understanding Evolution and onto elements on this large website more closely connected to the realms of research science. Animation that introduces the concept of genetics links to a page that highlights John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.

The Evolution Library on this website has a huge multimedia library of resources that are associated with evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives outlined in biology standards. It contains seven videos specifically designed for use in classrooms, and 에볼루션 코리아 can be streamed at no cost or purchased on DVD.

Evolutionary biology remains a field of study with a lot of important questions to answer, 에볼루션 슬롯 such as the causes of evolution and the speed at which it takes place. This is especially true for humans' evolution which was a challenge to reconcile religious beliefs that held that humanity has a unique place in creation and a soul, with the idea that innate physical traits evolved from the apes.

There are a variety of other ways evolution can occur including natural selection, which is the most well-known theory. However scientists also study other types of evolution such as mutation, genetic drift and sexual selection, among others.

While many fields of scientific study have a conflict with the literal interpretations of religious texts, evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, others aren't.
