Speak "Yes" To These 5 Evolution Site Tips

Evolution Site - Teaching About Evolution

Despite the best efforts of 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, which is a companion to the PBS series - provides teachers with materials that support evolution education and avoids the kinds of misinformation that can hinder it. It's organized in a "bread crumb" format to make navigation and orientation easier.

Definitions

It's difficult to effectively teach evolution. It is often misunderstood even by non-scientists, and even some scientists are guilty of using an interpretation that is confusing the issue. This is particularly true when discussing the definition of the words.

It is essential to define terms used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient way. It is an accompanying site for the 2001 series, and also a resource of its own. The information is presented in a structured way that makes it easy to navigate and comprehend.

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

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

The process of adaptation is the tendency of heritable traits to be more suitable to their environment. This is the result of natural selection, which occurs when organisms that have better-adapted traits are more likely to survive and reproduce than those with less adapted characteristics.

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

Deoxyribonucleic acid: A massive biological molecule that contains information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, called chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

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

Origins

Species (groups of individuals who can interbreed) develop through natural changes in the characteristics of their offspring. The changes can be caused by a variety of factors, including natural selection, genetic drift, and mixing of genes. The development of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food or habitat can impede or accelerate the process.

The Evolution site tracks the evolution of a variety of animal and 에볼루션바카라 plant groups through time with a focus on the key shifts that occurred throughout each group's history. It also focuses on the human evolutionary roots and humans, a subject that is especially important for students to understand.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany which is now believed to be 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 extremely unlikely that Darwin had heard or seen of it.

The site is primarily one of biology however it also includes a lot of information on geology and paleontology. One of the most appealing features of the website are a set of timelines that illustrate the way in which climatic and geological conditions changed over time, and a map of the geographical distribution of some fossil groups that are featured on the site.

The site is a companion for 에볼루션코리아 a PBS TV series but it can also be used as a source for teachers and students. The site is well-organized and offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also links to John Endler's experiments with guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology, the study of these creatures in their geological environment offers many advantages over the current observational or experimental methods for exploring evolutionary processes. Paleobiology focuses on not only the process and events that happen regularly or over time but also the relative abundance and distribution of different species of animals in space over the course of the geological time.

The site is divided into various paths that can be chosen to learn about evolution. One of these paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The path also examines myths regarding evolution, as well as the history of evolutionary thought.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that can be used to support a variety of levels of curriculum and teaching methods. The site includes a variety of multimedia and interactive resources, including videos, animations, and virtual laboratories in addition to general textual content. The breadcrumb-like arrangement of the content aids in navigation and orientation on the vast website.

The page "Coral Reef Connections", for example, gives a brief overview of the coral's relationships and their interactions with other organisms and is enlarged to show a single clam, 에볼루션코리아 which is able to communicate with its neighbours and respond to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary, multimedia, 에볼루션 and interactive pages on the site, provide an excellent introduction to a wide range of topics in evolutionary biology. The material includes an explanation of the importance of natural selection and the concept phylogenetics analysis as a key method for understanding the evolution of change.

Evolutionary Theory

For biology students evolution is a crucial thread that binds all the branches of the field. A wide range of resources helps teachers teach about evolution across all life sciences.

One resource, 에볼루션 룰렛 which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth as well as wide range of educational resources. The site has a variety of interactive learning modules. It also features an embedded "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this huge site that are closer to the field of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page that highlights John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

Another helpful resource is the Evolution Library on this Web website, which includes an extensive library of multimedia resources that are related to evolution. The content is organized according to curriculum-based paths that parallel the learning objectives set out in biology standards. It contains seven videos designed specifically for use in the classroom, 에볼루션코리아 and can be streamed at no cost or purchased on DVD.

Evolutionary biology remains a field of study with a lot of important questions, including the causes of evolution and the speed at which it happens. This is particularly applicable to human evolution where it's been difficult to reconcile the idea that the physical traits of humans were derived from apes and religious beliefs that hold that humans are unique among living things and has an enviable place in creation. It is soul.

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

While many fields of scientific inquiry have a conflict with the literal interpretations of religious texts Evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Certain religions have reconciled their beliefs to evolution but others haven't.
