10 Healthy Evolution Site Habits

Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, there are still a lot of misconceptions regarding evolution. Pop science nonsense has led people to believe that biologists aren't believers in evolution.

This rich Web site, which is a companion to the PBS program offers teachers resources which support evolution education, while avoiding the kinds of misconceptions that undermine it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to properly teach evolution. It is often misunderstood even by non-scientists, and even scientists are guilty of using an interpretation that is confusing the issue. This is particularly true when it comes to debates about the definition of the word itself.

It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site is a companion to the show which first aired in 2001, but also functions as an independent resource. The material is presented in a way that assists in navigation and orientation.

The site defines terms like common ancestor and the gradual process. These terms help to define the nature and relationship of evolution to other concepts in science. The website then provides an overview of how the concept of evolution has been tested and verified. This information can help dispel the myths that are created by the creationists.

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

Adaptation is the tendency of hereditary traits to become better suited to an environment. This is due to natural selection, which occurs when organisms with better-adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.

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

Deoxyribonucleic Acid: A large biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

Coevolution is a relationship between two species where evolution of one species are influenced by evolutionary changes of the other. Examples of coevolution include the interactions between predator and prey or host and parasite.

Origins

Species (groups of individuals who can interbreed) change through a series of natural changes in the traits of their offspring. The causes of these changes are 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 could be slowed down or accelerated due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site tracks through time the evolution of various animal and plant groups with a focus on major changes within each group's past. It also examines the evolution of humans and is a subject that is of particular interest to students.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans were discovered. The famous skullcap, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap when it was published in 1858, which was a year after the publication of the first edition of The Origin. Origin.

While the site is focused on biology, it also includes a good deal of information about geology as well as paleontology. One of the most appealing features of the Web site are a series of timelines which show how geological and climatic conditions changed over time, as well as a map of the distribution of some of the fossil groups featured on the site.

The site is a companion for a PBS TV series but it could also be used as a resource by teachers and students. The site is very well-organized and has clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and 에볼루션바카라 the more specific elements of the museum's web site. These hyperlinks facilitate the move from the enthralling 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. They illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced an array of animals, plants and insects. Paleobiology, 에볼루션 사이트 the study of these creatures in their geological environment, has many advantages over the current observational or experimental methods for studying evolutionary processes. In addition to examining processes and 에볼루션게이밍 events that occur regularly or 에볼루션 바카라 over a lengthy period of time, paleobiology allows to analyze the relative abundance of various groups of organisms and their distribution throughout geological time.

The site is divided into several optional ways to learn about evolution which include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence supporting the theory of evolution. The course also focuses on misconceptions about evolution and also the history of evolutionary thought.

Each of the other 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. The site offers a wide array of interactive and multimedia content which include video clips, 에볼루션 무료체험 animations and virtual labs, in addition to its general textual content. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the vast Web site.

The page "Coral Reef Connections", for example, provides a comprehensive overview of the coral's relationships and their interactions with other organisms, and then zooms in on one clam that is able communicate with its neighbours and respond to changes in the conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to the broad spectrum of topics in evolutionary biology. The material includes an explanation of the importance of natural selection and the concept of phylogenetics as a key tool to understand evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life science.

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that offers both depth as well as wide range of educational resources. The site offers a variety of interactive learning modules. It also features an "bread crumb structure" that helps students move away from the cartoon-like style that is used in Understanding Evolution and onto elements on this site that are more closely linked to the worlds of research science. An animation that introduces students to the concept of genetics is linked to a page about John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.

The Evolution Library on this website contains a large multimedia library of materials that deal to evolution. The content is organized into curricula-based pathways that correspond to the learning objectives outlined in biology standards. It includes seven short videos specifically designed for use in the classroom, and can be streamed for free or purchased on DVD.

A variety of crucial questions remain at the core of evolutionary biology, including what causes evolution to occur and the speed at which it occurs. This is especially true for human evolution, where it's been difficult to reconcile that the physical traits of humans evolved from apes with religions that believe that humanity is unique among living things and has a special place in creation with a soul.

There are a variety of other ways in which evolution can take place and natural selection being 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 scientific fields of inquiry are in conflict with the literal interpretations of religious texts, evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs to evolution but others haven't.
