Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution persist. People who have taken in the nonsense of pop science often believe that biologists are saying they do not believe in evolution.

This rich Web site, which is a complement to the PBS program that provides teachers with resources that support the evolution of education, while avoiding the kinds of misconceptions which hinder it. It's arranged in a nested "bread crumb" format for ease of navigation and 에볼루션 사이트 에볼루션 바카라 무료체험 사이트 (Lt.Dananxun.cn) orientation.

Definitions

Evolution is a complex and difficult subject to teach well. It is often misunderstood by non-scientists and even some scientists are guilty of using an interpretation that is confusing the issue. This is especially relevant to discussions about the nature of the word.

It is therefore important to define the terms used in evolutionary biology. Understanding Evolution's website does this in a straightforward and useful way. The site is a companion site to the show which first aired in 2001, but it is also an independent resource. The content is presented in an organized way that makes it easy to navigate and comprehend.

The site defines terms such as common ancestor, the gradual process, and adaptation. These terms help frame the nature of evolution as well as its relation to other scientific concepts. The site provides an overview of the way in which evolution has been tested. This information can be used to dispel misconceptions that have been engendered by creationists.

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

Adaptation is the tendency of heritable traits to be more suited to the environment. This is a result of natural selection. It occurs when organisms with more adaptable traits are more likely to survive and reproduce than those with less adaptable traits.

Common ancestor (also called common ancestor) The most recent 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 containing the information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are the source of new genetic information in cells.

Coevolution: A relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey, or the parasite and the host.

Origins

Species (groups of individuals that can interbreed) evolve through an array of natural changes in the traits of their offspring. The changes can be caused by a variety that include natural selection, genetic drift, and mixing of gene pools. The evolution of new species could take thousands of years. Environmental conditions, such as changes in the climate or competition for food or habitat, can slow or accelerate the process.

The Evolution site follows the emergence of various groups of animals and plants and focuses on major changes in each group's past. It also focuses on the evolutionary history of humans which is particularly important for students to know.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. One of them was the infamous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was first published in 1858, a year following the initial edition of The Origin.

While the site focuses on biology, it also offers a lot of information about geology as well as paleontology. One of the most appealing features of the website are a timeline of events that illustrate how climatic and geological conditions have changed over time, as well as an outline of the geographical distribution of some fossil groups that are featured on the site.

The site is a companion for a PBS television series, but it can be used as a resource by teachers and students. The site is very 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 components of the museum's Web site. These hyperlinks make it easy to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. In particular there are links to John Endler's research with Guppies, 에볼루션 카지노 바카라 체험; www.thehomeautomationhub.com, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants, 에볼루션 바카라 체험 and insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over the current observational and experimental methods of examining evolutionary processes. In addition to examining processes and events that take place regularly or over a lengthy period of time, paleobiology allows to study the relative abundance of different kinds of organisms as well as their distribution in space over the course of geological time.

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

Each of the main sections of the Evolution website is equally well-developed, with materials that support a variety curriculum levels and teaching styles. The site includes a variety of interactive and multimedia resources that include animations, video clips and virtual labs as well as general textual content. The breadcrumb-like arrangement of the content helps with navigation and orientation on the massive web site.

The page "Coral Reef Connections", for example, gives a brief overview of the relationships between corals and interactions with other organisms, and then zooms in to one clam that is able communicate with its neighbors and 에볼루션 바카라 체험 respond to changes in the conditions of the water that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages provides an excellent introduction to many topics in evolutionary biology. The information 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

Evolution is a common thread that connects all branches of biology. A vast collection of resources can help teachers teach about evolution across the life sciences.

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that provides depth as well as wide range of educational resources. The site features a wide range of interactive learning modules. It also has an embedded "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely linked to the field of research science. For example an animation that introduces the concept of genetic inheritance links to a page that focuses on John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website is a vast multimedia library of assets related with evolution. The content is organized according to curriculum-based paths that parallel the learning goals established in the standards for biology. It includes seven short videos designed specifically for classroom use, which can be streamed for free or purchased on DVD.

Evolutionary biology remains an area of study that poses many important questions, such as what causes evolution and how quickly it happens. This is particularly true for human evolution, where it's been difficult to reconcile the idea that the innate physical characteristics of humans were derived from apes with religious beliefs that claim that humans are unique among living things and has an exclusive place in the creation, with a soul.

In addition there are a myriad of ways in which evolution could be triggered with natural selection being the most popular theory. Scientists also study different types such as genetic drift and sexual selection.

Many fields of inquiry are in conflict with literal interpretations of religious texts Evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, while others haven't.
