Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions about the evolution. Pop science nonsense has led many people to think that biologists don't believe in evolution.

This rich Web site, a companion to the PBS program, provides teachers with materials which support evolution education, while avoiding the kinds of misconceptions which undermine it. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complex and difficult subject matter to teach well. It is often misunderstood by non-scientists and even some scientists use a definition that confuses the issue. This is particularly true when it comes to discussions on the definition of the word itself.

It is therefore crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The website is a companion to the show that premiered in 2001, but can also function as an independent resource. The information is presented in a structured manner that makes it easier to navigate and understand.

The site defines terms like common ancestor, gradual process and so on. These terms help to frame the nature of evolution and its relation to other concepts in science. The website provides a summary of the ways in which evolution has been tested. This information can be used to dispel misconceptions that have been created by the creationists.

You can also access a glossary which includes 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 a result of natural selection, which occurs when organisms that are better-adapted characteristics are more likely to survive and reproduce than those with less adaptable characteristics.

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

Deoxyribonucleic Acid: 에볼루션 사이트 A huge biological molecular that holds the necessary information for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are the cause of new genetic information within cells.

Coevolution is a relation between two species, where the evolution of one species influence evolutionary changes of the other. Examples of coevolution include the interactions between predator and 에볼루션 코리아 prey or the parasite and the host.

Origins

Species (groups of individuals who can interbreed) evolve through an array of natural changes in the characteristics of their offspring. The changes can be triggered by a variety of causes, including natural selection, genetic drift, and mixing of genes. The evolution of new species can take thousands of years. Environmental circumstances, such as climate change or competition for food resources and habitat, can slow or accelerate the process.

The Evolution site traces the emergence of a number of different groups of animals and plants over time and focuses on the most significant shifts that occurred throughout each group's history. It also examines the evolutionary history of humans which is especially important for students to know.

Darwin's Origin was published in 1859, at a time when only a handful of antediluvian fossils of humans had been found. The famous skullcap, along with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was published in 1858, a year after the first edition of The Origin.

The site is mostly a biology site however it also includes lots of information about geology and paleontology. The website has numerous features that are especially impressive, such as a timeline of how climate and geological conditions have changed over the course of time. It also includes an interactive map that shows the location of fossil groups.

While the site is a companion piece to a PBS television series but it also stands on its own as an excellent resource for teachers and 무료에볼루션 students. The site is well-organized and 에볼루션 블랙잭 offers clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's support) and 에볼루션 슬롯게임 블랙잭 (mouse click the next document) the more specific features of the museum website. These hyperlinks facilitate the move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies that illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology is the study of these creatures within their geological context and has numerous advantages over the modern observational and research methods for analyzing evolutionary phenomena. In addition to exploring processes and events that occur regularly or over a lengthy period of time, paleobiology can be used to analyze the relative abundance of various species of organisms and their distribution in space over the geological time.

The Web site is divided into a variety of pathways to understanding evolution, including "Evolution 101," which takes the user on a linear path through the science of nature and the evidence that supports the theory of evolution. The path also reveals common misconceptions about evolution and the history of evolutionary 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 offers a wide array of multimedia and interactive resources, including video clips, animations and virtual labs in addition to general textual content. The content is presented in a nested bread crumb-like fashion that helps with navigation and orientation on the web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of the relationships between corals, their interaction with other organisms and zooms in to one clam that is able communicate with its neighbours and respond to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a wide variety of topics in evolutionary biology. The material also provides a discussion of the role of natural selection as well as the concept of phylogenetic analysis, which is a crucial method to understand evolutionary change.

Evolutionary Theory

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

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that offers both the depth and the breadth in terms of its educational resources. The site has a variety of interactive learning modules. It also features an "bread crumb structure" that helps students move away from the cartoon style used in Understanding Evolution and onto elements on this site that are more closely linked to the worlds of research science. Animation that introduces the concept of genetics links to a page highlighting John Endler's experiments with artificial selection using Guppies in native ponds in Trinidad.

Another helpful resource is the Evolution Library on this site, which contains an extensive library of multimedia resources that are related to evolution. The content is organized into curricula-based paths that correspond to the learning objectives outlined in biology standards. It contains seven videos that are designed for use in classrooms. They can be viewed online or purchased as DVDs.

Evolutionary biology is still a field of study that poses many important questions, including what causes evolution and the speed at which it happens. This is especially applicable to human evolution where it has been difficult to reconcile that the physical traits of humans were derived from apes and 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 widely accepted theory. Scientists also study other kinds such as genetic drift, 에볼루션 무료체험 (this website) and sexual selection.

While many scientific 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 embraced their beliefs with evolution, while others haven't.
