Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. Pop science nonsense has led many people to think that biologists don't believe 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 which hinder it. It's laid out in a "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and challenging subject to teach well. People who are not scientists often have a difficult time understanding the subject, and some scientists even employ a definition that confuses it. This is particularly true when discussing the nature of the words themselves.

It is therefore essential to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, 에볼루션 바카라 does this in a clear and helpful way. It is an accompanying site for the 2001 series, and also a resource of its own. The material is presented in a nested fashion that aids navigation and orientation.

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

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

Adaptation is the tendency of heritable traits to become more suitable to their environment. This is the result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less-adapted traits to reproduce and survive.

Common ancestor (also known as common ancestor): The most recent ancestral ancestor shared by two or more species. By analyzing DNA from these species, it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

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

Origins

Species (groups that can interbreed) develop through a series of natural changes in the traits of their offspring. The changes can be triggered by a variety of factors, including natural selection, genetic drift and mixing of gene pools. The development of a new species can take thousands of years, and the process can be slowed down or accelerated by environmental factors like climate change or competition for food or habitat.

The Evolution site traces the emergence of a variety of groups of animals and plants over time with a focus on the key changes that took place in each group's history. It also explores the evolutionary origin of humans which is particularly important for students to know.

Darwin's Origin was written in 1859, when only a few antediluvian fossils of humans had been found. One of them was the infamous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year after the first edition of the Origin was published, it is highly unlikely that Darwin had ever heard of it.

The site is mostly an online biology resource however, 에볼루션 무료 바카라 it also has a lot of information on geology and paleontology. The most impressive features on the site are a series of timelines that illustrate the way in which climatic and geological conditions have changed over time, as well as an interactive map of the geographical distribution of some fossil groups listed on the site.

Although the site is a companion piece to the PBS television show but it also stands on its own as a great 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 funding) as well as the more specialized features of the museum's website. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are hyperlinks to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in many species of animals, plants and insects. Paleobiology is the study of these creatures within their geological environment, has many advantages over modern observational or experimental methods for studying evolutionary phenomena. In addition to examining the processes and events that happen regularly or over a lengthy period of time, paleobiology allows to analyze the diversity of species of organisms and their distribution throughout the course of geological time.

The site is divided into a variety of 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 to support the theory of evolution. The path also reveals the most common misconceptions about evolution, as well as the evolution of thought.

Each of the other major sections of the Evolution site is similarly developed, with materials that can be used to support a range of curriculum levels and pedagogical styles. In addition to the general textual content, the site features a wide range of multimedia and interactive content, such as video clips, animations, and virtual labs. The content is laid out in a nested bread crumb style that facilitates navigation and orientation within the vast web site.

For example the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interactions with other organisms, then zooms in on a single clam that can communicate with its neighbours and respond to changes in the water conditions that take place at the level of the reef. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a wide variety of topics in evolutionary biology. The content also includes a discussion of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool in understanding evolutionary change.

Evolutionary Theory

For biology students evolution is a crucial thread that binds all branches of the field. A vast collection of resources can help teachers teach about evolution across the life sciences.

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that offers both depth and breadth in terms of its educational resources. The site has a variety 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 large Web site closer to the field of research science. For example, an animation introducing the concept of genetic inheritance links to a page highlighting John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of resources that are associated with evolution. The contents are organized into courses that are based on curriculum and follow the learning goals established in the standards for biology. It includes seven short videos specifically designed for use in the classroom, and can be streamed at no cost or 에볼루션 바카라 무료 무료 에볼루션 바카라 (Heavenarticle.com) purchased on DVD.

Evolutionary biology is a field of study that has many important questions, such as what triggers evolution and how fast it occurs. This is especially applicable to human evolution which has made it difficult to reconcile that the physical characteristics of humans evolved from apes, and the religious beliefs that claim that humans are unique among living things and holds a an enviable place in creation. It is a soul.

There are a variety of other ways in which evolution can take place including natural selection, which is the most widely accepted theory. Scientists also study other kinds such as mutation, genetic drift and sexual selection.

While many scientific fields of inquiry conflict with literal interpretations of religious texts Evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, others haven't.
