10 Healthy Evolution Site Habits

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. People who have been exposed to the nonsense of pop science often believe that biologists do not believe in evolution.

This rich website - companion to the PBS series - provides teachers with materials which support evolution education and help avoid the kinds of myths that make it difficult to understand. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to effectively teach evolution. It is often misunderstood by non-scientists, and even some scientists use an interpretation that is confusing the issue. This is especially relevant to debates about the nature of the word.

It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. It is an accompaniment to the 2001 series, but also a resource on its own. The material is presented in a nested fashion that aids navigation and orientation.

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

You can also consult a glossary that contains terms that are used in evolutionary biology. These terms include:

Adaptation: The tendency of heritable characteristics to become more adaptable to a specific environment. This is the result of natural selection, which occurs when organisms that have more adaptable characteristics are more likely to survive and reproduce than those with less adapted characteristics.

Common ancestor: The most recent common ancestor of two or more different species. By analyzing the DNA from these species, 에볼루션 슬롯 무료 바카라 (similar webpage) it is possible to determine the common ancestor.

Deoxyribonucleic acid: A massive biological molecule that contains the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is the relationship between two species, where the evolution of one species influence evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasite and hosts.

Origins

Species (groups that can crossbreed) change by a series of natural variations in the traits of their offspring. These changes are caused by a variety such as natural selection, genetic drift, and mixing of gene pools. The evolution of new species could take thousands of years. Environmental conditions, like climate changes or competition for food or habitat can slow or speed up the process.

The Evolution site tracks through time the evolution of various animal and plant groups with a focus on major changes within each group's past. It also explores the evolutionary origin of humans which is crucial for students to comprehend.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. Among them was the famous skullcap and the associated bones discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year before the first edition of the Origin appeared, it is extremely unlikely that Darwin had heard or seen of it.

The site is mostly a biology site however it also includes many details on geology and paleontology. The site offers numerous features that are particularly impressive, including an overview of how geological and climate conditions have changed over the course of time. It also has an interactive map that shows the location of fossil groups.

The site is a companion for the PBS TV series but it could also be used as a source for teachers and students. The site is very well organized and provides clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are 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 plants, animals, and 에볼루션코리아 insects. Paleobiology is the study of these creatures within their geological environment, has many advantages over modern observational or experimental methods for exploring evolutionary processes. Paleobiology can examine not just the processes and events that happen regularly or over time, but also the distribution and frequency of various animal groups 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," takes the viewer through the nature and evidence of evolution. The course also focuses on misconceptions regarding evolution, and the background of evolutionary thinking.

Each of the main sections on the Evolution website is equally well-developed, and includes materials that can be used to support a variety of educational levels and teaching styles. The site includes a variety of interactive and multimedia resources that include videos, 에볼루션 바카라 체험 animations, and virtual labs as well as general textual content. The breadcrumb-like arrangement of the content helps with navigation and orientation on the vast website.

For instance, the page "Coral Reef Connections" gives a brief overview of the relationships between corals and their interaction with other organisms. It then narrows down to a single clam that can communicate with its neighbours and 에볼루션 무료 바카라 respond to changes in water conditions that occur at the level of the reef. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a wide range of topics in evolutionary biology. The content also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is a key tool in understanding evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A vast collection of resources can help teachers teach about evolution across the life sciences.

One resource, the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both the depth and the wide range of educational resources. The site offers a range of interactive learning modules. It also features an encased "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 world of research science. For example an animation that explains the notion of genetic inheritance leads to a page highlighting John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.

Another helpful resource is the Evolution Library on this site, which contains an extensive library of multimedia items that are related to evolution. The content is organized according to curriculum-based paths that parallel the learning goals established in biology standards. It contains seven videos specifically designed for use in classrooms, and can be streamed for free or purchased on DVD.

Evolutionary biology remains a field of study with a lot of important questions, including what triggers evolution and the speed at which it takes place. This is especially applicable to human evolution which has made it difficult to reconcile that the innate physical characteristics of humans were derived from apes, and the religious beliefs that claim that humanity is unique in the universe and has a special place in creation, 에볼루션 무료 바카라 with soul.

In addition there are a myriad of ways that evolution can occur with natural selection being the most popular theory. Scientists also study other types like mutation, genetic drift and sexual selection.

Although many scientific fields of study conflict with the literal interpretations of religious texts, evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
