Evolution Site - Teaching About Evolution

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

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

Definitions

Evolution is a complicated and challenging subject to teach well. It is often misunderstood by non-scientists and even some scientists have been guilty of using an interpretation that is confusing the issue. This is especially true when discussing the definition of the words.

It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. It is an accompanying site for the 2001 series, but it is also a resource on its own. The content is organized in a manner that makes it simpler to navigate and understand.

The site defines terms such as common ancestor, gradual process, and adaptation. These terms help to frame the nature of evolution as well as its relationship to other concepts in science. The site gives a comprehensive overview of the ways that evolution has been tested. This information can be used to dispel the myths that have been created by the creationists.

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

The process of adaptation is the tendency of heritable traits to become better suited to an environment. This is due to natural selection. It occurs when organisms that are better adapted traits are more likely survive and reproduce than those with less adaptable traits.

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

Deoxyribonucleic Acid: A massive biological molecular containing the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the source of new genetic information in cells.

Coevolution is the relationship between two species in which the evolution of one species are influenced evolutionary changes of the other. Coevolution can be observed through the interaction between predator and prey, or parasite and hosts.

Origins

Species (groups of individuals that can interbreed) evolve through an array of natural changes in the characteristics of their offspring. These changes are caused by a variety of factors such as natural selection, genetic drift, and mixing of genes. The development of a new species could take thousands of years and the process can be slowed down or accelerated by environmental factors like climate change or the competition for food or habitat.

The Evolution site tracks through time the evolution of different animal and plant groups, focusing on major transitions within each group's past. It also focuses on the human evolutionary roots which is particularly important for students to understand.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of human beings had been discovered. 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 as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap when it was published in 1858, a year after the publication of the first edition of The Origin. Origin.

The site is primarily an online biology resource, but it also contains many details on geology and paleontology. One of the most appealing features of the website are a timeline of events that illustrate how climatic and geological conditions changed over time, as well as an outline of the distribution of a few of the fossil groups featured on the site.

Although the site is a companion to a PBS television series, it also stands on its own as a valuable source for teachers and students. The site is very well organized and provides clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has resulted in a variety of plants, animals, and insects. Paleobiology is the study of these creatures within their natural environment and has numerous advantages over the current observational and experimental methods in its exploration of evolutionary phenomena. Paleobiology can examine not only the process and events that take place frequently or over time, but also the relative abundance and distribution of different species of animals in space throughout geological time.

The Web site is divided into a variety of paths to learning evolution that include "Evolution 101," which takes the viewer on a liner path through the scientific process and the evidence that supports the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought.

Each of the other main sections of the Evolution site is similarly constructed, with materials that support a variety of different pedagogical levels and curriculum levels. The site offers a wide array of interactive and multimedia resources that include animations, video clips and virtual labs, in addition to its general textual content. The breadcrumb-like structure of the content assists with navigation and orientation on the massive Web site.

For instance the page "Coral Reef Connections" gives a brief overview of coral relationships and their interaction with other organisms, then narrows down to a single clam that can communicate with its neighbors and react to changes in the water conditions that take place at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages offers a great introduction to many topics in evolutionary biology. The information also includes an overview of the importance of natural selection and the concept of phylogenetic analysis which is a key tool in understanding evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life sciences.

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides the depth and the wide range of educational resources. The site features a wide range of interactive learning modules. It also features a "bread crumb structure" that allows students to move away from the cartoon style used in Understanding Evolution and onto elements on this site that are more closely linked to the fields of research science. For 에볼루션 example an animation that introduces the notion of genetic inheritance leads to a page that highlights John Endler's experiments in artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives set out in biology standards. It contains seven videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.

A number of important questions remain at the heart of evolutionary biology, 에볼루션 카지노 사이트 바카라 - Www.youtube.com, including what triggers evolution and how fast it occurs. This is especially true for humans' evolution which was a challenge to reconcile religious beliefs that humans have a distinct place in the creation and a soul, with the notion that human beings have innate physical traits evolved from apes.

There are also a number of other ways evolution could occur including natural selection, which is the most well-known theory. Scientists also study different types such as mutation, genetic drift and 에볼루션코리아 sexual selection.

Although many scientific fields of study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been a source of intense debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, but others haven't.
