Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. People who have taken in popular science myths often assume that biologists claim they do not believe in evolution.

This rich website - companion to the PBS series It provides teachers with materials that support evolution education and avoids the kinds of misinformation that can make it difficult to understand. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complicated and difficult subject matter to teach effectively. Non-scientists often misunderstand the subject, and some scientists even use a definition that confuses it. This is particularly applicable to discussions on the nature of the word.

As such, it is essential to define terms that are used in evolutionary biology. The website for the PBS show, 에볼루션바카라 Understanding Evolution, does this in a clear and helpful manner. The site is a companion to the show which first aired in 2001, but is also an independent resource. The information is presented in an organized way that makes it easy to navigate and comprehend.

The site defines terms such as common ancestor, gradual process and so on. These terms help to frame the nature of evolution and its relationship to other concepts in science. The site then offers an overview of how the concept of evolution has been vetted and verified. This information can be used to dispel the myths that have been created by creationists.

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

The process of adaptation is the tendency of hereditary traits to become more suitable to their environment. This is a result of natural selection, which occurs when organisms with better adapted traits are more likely survive and reproduce than those with less adapted characteristics.

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

Deoxyribonucleic acid: A huge biological molecule that holds the information required for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

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

Origins

Species (groups of individuals that are able to interbreed) develop through a series of natural changes in the traits of their offspring. The changes can be triggered by a variety of causes such as natural selection, genetic drift, 에볼루션 and mixing of genes. The evolution of new species can take thousands of years. Environmental conditions, like climate change or competition for food or habitat can slow or speed up the process.

The Evolution site traces the emergence of a variety of groups of animals and plants over time with a focus on the key shifts that occurred throughout each group's history. It also focuses on human evolution and is a subject of particular importance for students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was one year after the first edition of the Origin appeared, it is very unlikely that Darwin had ever heard of it.

The site is mostly one of biology however it also includes a lot of information on geology and paleontology. The website has several features that are especially impressive, such as a timeline of how climate and geological conditions have changed over the course of time. It also has a map showing the distribution of fossil groups.

The site is a companion for the PBS TV series but it could also be used as a resource by teachers and students. The site is extremely well-organized and has clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These links facilitate the transition from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are hyperlinks to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of animals, plants and 에볼루션 바카라 무료체험 insects. Paleobiology is the study of these creatures in their natural environment and has many advantages over modern observational and experimental methods for analyzing evolutionary processes. Paleobiology focuses on not only processes and events that happen regularly or over time but also the relative abundance and distribution of different species of animals in space throughout geological time.

The site is divided into several optional pathways to understanding evolution that include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence that supports the theory of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thought.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that are suited to a variety of levels of curriculum and teaching methods. In addition to the standard textual content, the site offers an extensive selection of multimedia and interactive resources, such as videos, animations, and virtual laboratories. The breadcrumb-like structure of the content aids in navigation and orientation on the large web site.

For example the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interaction with other organisms. Then, it zooms in on a single clam that is able to communicate with its neighbors and respond to changes in water conditions at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages offers a great introduction to a variety of topics in evolutionary biology. The material also provides an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is an important method to understand evolutionary change.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A rich collection of resources helps teachers teach about evolution across all life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that provides depth and a variety of educational resources. The site has a variety of interactive learning modules. It also has a nested "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the field of research science. An animation that introduces the concept of genetics, which links to a page highlighting John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated to evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives set out in biology standards. It contains seven short videos specifically intended for use in the classroom. They can be streamed or 에볼루션 무료 바카라 purchased as DVDs.

Evolutionary biology is an area of study that has many important questions, such as what triggers evolution and how fast it takes place. This is particularly true for the evolution of humans, where it was difficult to reconcile religious beliefs that held that humanity has a unique place in creation and a soul, with the idea that innate physical traits originated from apes.

Additionally there are a variety of ways that evolution could be triggered and natural selection is the most widely accepted theory. However scientists also study different kinds of evolution, such as mutation, genetic drift and sexual selection, among others.

While many fields of scientific study are in 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 with evolution, while others haven't.
