Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution remain. People who have taken in popular science myths often assume that biologists don't believe in evolution.

This site, which is a complement to the PBS program offers teachers resources that support the evolution of education while avoiding the types of misconceptions that can make it difficult to understand. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and difficult subject to teach well. It is often misunderstood by non-scientists, and even some scientists are guilty of using a definition that confuses the issue. This is especially relevant when it comes to the nature of the words themselves.

It is therefore crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful way. The website is a companion to the show that premiered in 2001, but also functions as an independent resource. The material is organized in a manner that makes it simpler to navigate and comprehend.

The site defines terms like common ancestor and gradual process. These terms help to define the nature of evolution as well as its relationship to other concepts in science. The site gives a comprehensive overview of the ways the concept of evolution has been tested. This information can help dispel myths that are created by the creationists.

You can also access a glossary which 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 with better-adapted characteristics are more likely than those with less adapted characteristics to survive and reproduce.

Read More Listed here : The latest common ancestor of two or more distinct species. By studying the DNA of these species, it is possible to determine the common ancestor.

Deoxyribonucleic acid: A large biological molecule that contains the information required for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is a relation between two species, where the evolution of one species influence evolutionary changes in the other. Coevolution can be observed through the interaction between predator and prey, or parasites and hosts.

Origins

Species (groups which can interbreed) develop by a series of natural variations in their offspring's traits. 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 speeded up by environmental conditions such as climate change or competition for food or habitat.

The Evolution site traces through time the evolution of different animal and plant groups with a focus on major changes within each group's past. It also explores human evolution and is a subject that is particularly important to students.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans were discovered. The skullcap that is famous, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just a year before the first edition of the Origin was published, it's highly unlikely that Darwin had seen or heard of it.

While the site focuses on biology, it contains a wealth of information about geology and paleontology. The website has numerous aspects that are quite impressive, including an overview of how climate and geological conditions have changed over time. It also includes a map showing the distribution of fossil groups.

While the site is a companion to the PBS television show however, it can stand on its own as a great source for teachers and students. The site is extremely well-organized and offers clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler's experiments with guppies, which illustrate the importance 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 geological context and has many advantages over the modern observational and research methods of examining evolutionary phenomena. 에볼루션 바카라 무료체험 can examine not just the processes and events that occur regularly or over time but also the relative abundance and distribution of different species of animals in space over the course of geological time.

The site is divided into a variety of ways to learn about evolution that include "Evolution 101," which takes the viewer on a line through the science of nature and the evidence to support the theory of evolution. The course also focuses on common misconceptions about evolution and the evolution of thought.

Each of the other major sections of the Evolution site is equally well developed, with materials that can be used to support a range of educational levels and pedagogical styles. The site includes a variety of interactive and multimedia content which include animations, video clips and virtual laboratories, in addition to its general textual content. The content is laid out in a nested bread crumb fashion that aids navigation and orientation on the web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides an overview of coral relationships and interactions with other organisms and then is enlarged to show a single clam, which can communicate with its neighbours and respond to changes in water conditions that occur on the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, provides an excellent introduction to a variety of topics in evolutionary biology. The content includes a discussion on the role of natural selectivity and the concept of phylogenetics which is a crucial tool for understanding evolutionary change.

Evolutionary Theory

Evolution is a common thread that connects all branches of biology. A wide selection of resources helps teachers teach evolution across the disciplines of life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both the depth and breadth of its educational resources. 에볼루션 게이밍 features a wealth of interactive learning modules. It also features a "bread crumb structure" that allows students to move away from the cartoon-like style of Understanding Evolution and onto elements on this large website more closely connected to the realms of research science. For example an animation that explains the idea of genetic inheritance connects to a page that highlights John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.

Another helpful resource is the Evolution Library on this web site, which has an extensive multimedia library of assets connected to evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives set out in biology standards. It contains seven videos designed specifically for classroom use, which can be streamed for no cost or purchased on DVD.


Evolutionary biology is an area of study that has many important questions, such as what triggers evolution and how fast it happens. This is especially true for the evolution of humans which was a challenge to reconcile religious beliefs that held that humanity has a unique position in the universe and a soul with the notion that human beings have innate physical traits were derived from apes.

Additionally there are a variety of ways that evolution can be triggered, with natural selection being the most widely accepted theory. Scientists also study different types such as mutation, genetic drift and sexual selection.

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