Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution persist. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.

This rich Web site, which is a companion to the PBS program, provides teachers with materials that promote evolution education while avoiding the types of misconceptions that can hinder it. It's laid out in a "bread crumb" format to aid in navigation and orientation.

Definitions

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

It is therefore important to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful manner. The site serves as an accompanying site for 에볼루션 바카라 사이트 the 2001 series, and also a resource of its own. The material is presented in an organized way that makes it easy to navigate and understand.

The site defines terms such as common ancestor and gradual process. These terms help define the nature and significance of evolution to other scientific concepts. The website provides a summary of the ways in which evolution has been tested. This information can be used to dispel myths that have been engendered by creationists.

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

Adaptation is the tendency of heritable traits to be better suited to an environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less adaptable traits to survive and reproduce.

Common ancestor (also called common ancestor): The most recent ancestral ancestor shared by two or more species. By studying the DNA of these species it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular containing the information needed for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the cause of new genetic information in cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution include the interactions between predator and prey or parasite and host.

Origins

Species (groups that can crossbreed), evolve 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 mixing of gene pools. The evolution of new species can take thousands of years. Environmental conditions, like climate changes or competition for food resources and habitat, can slow or accelerate the process.

The Evolution site traces through time the evolution of different animal and plant groups and focuses on major changes in each group's past. It also examines the evolutionary origin of humans which is especially important for students to understand.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was first published in 1858, one year following the initial edition of The Origin.

The site is mostly an online biology resource however, it also has many details on paleontology and geology. Among the best features of the website are a series of timelines that show how geological and climatic conditions have changed over time, and a map of the geographical distribution of some fossil groups listed on the site.

Although the site is a companion piece to the PBS television series, it also stands on its own as a valuable source for teachers and students. The site is well-organized, and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features of the museum website. These hyperlinks make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler’s experiments with guppies, which illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced an array of plants, animals and insects. Paleobiology, the study of these creatures in their geological environment is a superior method of study over modern observational or experimental methods of studying evolutionary phenomena. In addition to studying processes and events that take place frequently or over a long period of time, paleobiology can be used to analyze the relative abundance of different species of organisms and their distribution across the course of geological time.

The website is divided into various paths to learning evolution, including "Evolution 101," which takes the viewer on a liner path through the nature of science and 에볼루션 블랙잭 the evidence to support the theory of evolution. The path also explores misconceptions about evolution, as well as the history of evolutionary thought.

Each of the other main sections of the Evolution site is equally developed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. In addition to the standard textual content, the site also has an extensive selection of multimedia and hi-couplering.com interactive resources, such as video clips, animations, and virtual laboratories. The content is organized in a nested, bread crumb style that facilitates navigation and orientation within the vast web site.

For example, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms. It then zooms in on a single clam that can communicate with its neighbors and respond to changes in water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages provides an excellent introduction to many topics in evolutionary biology. The content also includes an overview of the role of natural selectivity and the concept phylogenetics analysis, an important method for understanding the evolution of changes.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A vast collection of resources supports teaching about evolution across the life sciences.

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that offers both depth and 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 helps students transition from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the field of research science. An animation that introduces students to the concept of genetics is linked to a page about John Endler's experiments with artificial selection using Guppies in native ponds in Trinidad.

The Evolution Library on this website contains a large multimedia library of materials that deal with evolution. The content is organized into curricula-based pathways that correspond to the learning objectives outlined in the standards for biology. It contains seven videos designed for use in classrooms. They can be viewed online or purchased as DVDs.

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

In addition, there are a number of ways in which evolution could occur and 에볼루션 게이밍사이트 - http://www.maoflag.cc/home.php?mod=space&Uid=219561 - natural selection is the most popular theory. Scientists also study other types such as genetic drift and sexual selection.

While many fields of scientific study conflict with literal interpretations in religious texts, evolution biology has been the subject of intense debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution but others haven't.
