15 Evolution Site Benefits Everyone Must Be Able To

Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions regarding evolution. People who have been exposed to pop science nonsense often assume that biologists claim they don't believe in evolution.

This site, which is a companion to the PBS series - provides teachers with materials which support evolution education and avoid the kinds of myths that hinder it. It's organized in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

Evolution is a complex and difficult subject matter to teach effectively. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is especially applicable to debates about the nature of the word.

It is essential to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site serves as a companion for the 2001 series, and also a resource of its own. The material is organized in a way that makes it easy to navigate and understand.

The site defines terms like common ancestor, gradual process and adaptation. These terms help to frame the nature of evolution as well as its relation to other scientific concepts. The site provides an overview of the ways in which evolution has been examined.  에볼루션 슬롯  can be used to dispel myths that have been engendered by 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 more suitable to their environment. This is the result of natural selection, which happens when organisms that are more adaptable traits are more likely survive and reproduce than those with less adaptable traits.

Common ancestor: The most recent common ancestor of two or more species. The common ancestor can be identified by analyzing the DNA of these species.

Deoxyribonucleic Acid: A huge biological molecular containing the necessary information for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, also known as chromosomes. Mutations are the cause of new genetic information in cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be seen in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups which can interbreed), evolve by a series of natural variations in their offspring's traits. These changes can be caused by numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of a new species can take thousands of years and the process may be slowed down or accelerated by environmental factors like climate change or the competition for food or habitat.

The Evolution site traces through time the evolution of different species of plants and animals with a focus on major changes within each group's past. It also examines the evolutionary origin of humans, a topic that is particularly important for students to know.

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

While the site focuses on biology, it also includes a good deal of information about geology as well as paleontology. The Web site has several features that are especially impressive, including the timeline of how climate and geological conditions have changed over the course of time. It also has a map showing the distribution of fossil groups.

Although the site is a companion to a PBS television show but it also stands on its own as a valuable source for teachers and students. The site is well-organized and offers clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features on the museum's website. These hyperlinks make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are links to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced an array of animals, plants and insects. Paleobiology, the study of these creatures within their geological context, has many advantages over modern observational or research methods for exploring evolutionary phenomena. Paleobiology is able to study not only the process and events that take place regularly or over time, but also the relative abundance and distribution of different groups of animals in space throughout the geological time.

The website is divided into a variety of pathways to understanding evolution, including "Evolution 101," which takes the viewer on a line through the scientific process and the evidence that supports the theory of evolution. The course also focuses on misconceptions about evolution and also the history of evolutionary thought.

Each of the main sections of the Evolution website is equally well-designed, with materials that are suited to a variety of educational levels and teaching styles. The site has a range of interactive and multimedia content that include video clips, animations and virtual labs as well as general textual content. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the vast web site.

For instance, the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interaction with other organisms, then concentrates on a specific clam that is able to communicate with its neighbors and respond to changes in water conditions that occur at the level of the reef. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The content includes a discussion on the importance of natural selection and the concept of phylogenetics analysis, an important tool for understanding evolutionary changes.

Evolutionary Theory

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

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that provides the depth and the wide range of educational resources. The site has a wide array of interactive learning modules.  무료 에볼루션  features an "bread crumb structure" that helps students move away from the cartoon-like style used in Understanding Evolution and onto elements on this large website more closely linked to the fields of research science. For example, an animation introducing the concept of genetic inheritance links to a page that highlights John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website contains a large multimedia library of materials that deal to evolution. The contents are organized into curriculum-based paths that parallel the learning objectives set out in the biology standards. It includes seven short videos specifically designed for use in the classroom, and can be streamed for free or purchased on DVD.

Evolutionary biology is an area of study that poses many important questions, including what causes evolution and how quickly it happens. This is especially relevant to human evolution, which has made it difficult to reconcile the notion that the physical traits of humans were derived from apes and religions that believe that humanity is unique in the universe and has a special place in creation with soul.

There are a variety of other ways in which evolution can occur, with natural selection as the most popular theory. Scientists also study other types such as genetic drift and sexual selection.

Although many scientific fields of study conflict with literal interpretations in religious texts, the concept of evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, others aren't.
