Evolution Site - Teaching About Evolution

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

This site, a companion to the PBS program, provides teachers with materials that support the evolution of education, while avoiding the kinds of misconceptions that undermine it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It's not easy to properly teach evolution. It is often misunderstood by non-scientists, and even some scientists are guilty of using definitions that confuse the issue. This is especially relevant to discussions on the meaning of the word itself.

It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful way. The site is both a companion for the 2001 series, but also a resource on its own. The content is presented in a way which aids navigation and orientation.

The site defines terms like common ancestor, the gradual process and adaptation. These terms help to frame the nature of evolution and its relation to other scientific concepts. The site then offers 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.

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

Adaptation is the process of changing heritable traits to become more suitable to their environment. This is due to natural selection, which occurs when organisms with better-adapted traits are more likely survive and reproduce than those with less adaptable traits.

Common ancestor: 에볼루션 무료 바카라 The latest common ancestor of two or 에볼루션 사이트 more different species. The common ancestor can be identified by studying the DNA of the species.

Deoxyribonucleic Acid: A large biological molecular containing the information required for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution: A relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be seen through the interaction between predator and prey, or parasites and hosts.

Origins

Species (groups that can crossbreed) change through a series natural changes in the traits of their offspring. Changes can be caused by various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, such as clolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures in their geological context and has a number of advantages over the modern observational and research methods in its exploration of evolutionary processes. In addition to studying the processes and events that happen frequently or over a long period of time, paleobiology is able to examine the relative abundance of different groups of organisms and 에볼루션 바카라사이트 their distribution across geological time.

The site is divided into several paths that can be chosen to gain knowledge about evolution. One of the paths, "Evolution 101," walks the reader through the nature and evidence of evolution. The course also focuses on common misconceptions about evolution as well as the evolution of thought.

Each of the other sections of the Evolution site is equally well constructed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. In addition to general textual content, the site also has an array of multimedia and interactive resources including videos, animations and virtual labs. The breadcrumb-like arrangement of the content aids in navigation and orientation on the large Web site.

The page "Coral Reef Connections", for example, provides an overview of the relationships between corals, their interaction with other organisms, 에볼루션 사이트 and then zooms in to a single clam, 무료에볼루션 which is able to communicate with its neighbors and 에볼루션 바카라 무료 respond to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a wide spectrum of topics in evolutionary biology. The information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is an important tool for understanding the evolution of change.

Evolutionary Theory

Evolution is a common thread that runs through all branches of biology. A vast collection of books helps in teaching evolution across all disciplines of life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that offers both depth and a variety of educational resources. The site offers a range of interactive learning modules. It also features an embedded "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this massive website that are more closely linked to the world of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page highlighting John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

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

Evolutionary biology is a field of study that poses many important questions, such as what triggers evolution and how quickly it takes place. This is especially applicable to human evolution where it's been difficult to reconcile that the physical characteristics of humans derived from apes with religious beliefs that claim that humans are unique in the universe and has an enviable place in creation, with a soul.

There are a variety of other ways evolution could occur, with natural selection as the most popular theory. However scientists also study other types of evolution such as genetic drift, mutation, and sexual selection, among others.

While many fields of scientific inquiry are in conflict with literal interpretations of religious texts evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolution, but others haven't.
