The Good And Bad About Evolution Site

Evolution Site - Teaching About Evolution

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

This rich website - companion to the PBS series offers teachers with resources that promote evolution education and help avoid the kinds of myths that hinder it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to teach evolution well. Many non-scientists are unable to grasp the concept and some scientists employ a definition that confuses it. This is especially applicable to discussions about the meaning of the word itself.

It is important to define terms that are used in evolutionary biology. Understanding Evolution's website does this in a straightforward and useful manner. It is an accompanying site for the 2001 series, but also a resource on its own. The information is presented in a structured manner that makes it easier to navigate and understand.

The site defines terms such as common ancestor and gradual process. These terms help to define the nature of evolution as well as its relation to other concepts in science. The site gives a comprehensive overview of the way that evolution has been examined. This information can be used to dispel myths that have been propagated by the creationists.

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

Adaptation: The tendency for heritable traits to become better adaptable to a specific environment. This is the result of natural selection. It occurs when organisms with more adaptable characteristics are more likely to survive and reproduce than those with less adapted traits.

Common ancestor (also known as common ancestor) The most recent ancestral ancestor shared by two or more species. The common ancestor can be identified by analyzing the DNA of these species.

Deoxyribonucleic Acid: A massive biological molecular that contains the information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, referred to as chromosomes. Mutations are the basis for new genetic information within cells.

Coevolution is a relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be seen in the interactions between predator and prey, or parasites and hosts.

Origins

Species (groups that can interbreed), evolve through a series natural changes in their offspring's traits. These changes are caused by a variety, including natural selection, genetic drift and gene pool mixing. The evolution of a new species may take thousands of years, and the process could be slowed or increased by environmental conditions such as climate change or competition for food or habitat.

The Evolution site traces through time the evolution of different groups of animals and plants, focusing on major transitions within each group's past. It also examines the evolutionary history of humans and humans, a subject that is crucial for students to know.

Darwin's Origin was published in 1859, at a time when only a few antediluvian fossils of human beings had been discovered. The most famous among them was the skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was published in 1858, which was a year after the publication of the first edition of The Origin.

While the site is focused on biology, it contains a wealth of information about geology as well as paleontology. One of the most appealing features of the website are a series of timelines that illustrate how geological and climatic conditions changed over time, 에볼루션 바카라코리아 (crocusdance7.bravejournal.net) and a map of the distribution of some of the fossil groups featured on the site.

The site is a companion to the PBS TV series but it could also be used as an educational resource for 에볼루션 사이트 바카라사이트 (www.Nlvbang.com) teachers and students. The site is well-organized, and provides clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features on the museum's website. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are links to John Endler's research with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in many species of animals, plants and 에볼루션게이밍 insects. Paleobiology, the study of these creatures in their natural environment, has many advantages over modern observational or experimental methods for studying evolutionary processes. In addition to examining the processes and events that happen regularly or over a long period of time, paleobiology is able to study the relative abundance of various kinds of organisms as well as their distribution across the geological time.

The Web site is divided into several optional pathways to understanding evolution which include "Evolution 101," which takes the viewer on a line through the nature of science and the evidence to support the theory of evolution. The path also explores misconceptions about evolution, and the background of evolutionary thinking.

Each of the other sections of the Evolution site is equally developed, with materials that can support a variety of different pedagogical levels and curriculum levels. In addition to the standard textual content, the site also has an extensive selection of interactive and multimedia resources like video clips, animations, and virtual labs. The content is laid out in a nested bread crumb-like fashion that helps with 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 narrows down to a single clam that can communicate with its neighbours and respond to changes in water conditions that take place at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a broad range of topics in evolutionary biology. The content also includes an overview of the role of natural selectivity and the concept phylogenetics analysis which is a crucial method for understanding the evolution of change.

Evolutionary Theory

For biology students, evolution is a key thread that binds all branches of the field. A wide range of resources can help teachers teach about evolution across the life sciences.

One resource, the companion to PBS's television show 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 wealth of interactive learning modules. It also has an "bread crumb structure" that helps students move away from the cartoon style of Understanding Evolution and 에볼루션바카라 onto elements on this large website more closely related to the fields of research science. For instance an animation that introduces the idea of genetic inheritance connects to a page highlighting John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The contents are organized into courses that are based on curriculum and follow the learning objectives set out in the standards for biology. It contains seven short videos specifically designed for classroom use. These can be viewed online or purchased as DVDs.

Many important questions remain at the heart of evolutionary biology, including the factors that trigger evolution and the speed at which it occurs. This is especially true in the case of human evolution where it was a challenge to reconcile religious beliefs that humans have a distinct position in the universe and a soul with the idea that innate physical traits evolved from apes.

Additionally, there are a number of ways that evolution can occur, with natural selection being the most widely accepted theory. Scientists also study other types such as genetic drift and sexual selection.

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