10 Healthy Evolution Site Habits

Evolution Site - Teaching About Evolution

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

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

Definitions

Evolution is a complicated and challenging subject to teach effectively. It is often misunderstood even by non-scientists, and even some scientists use an interpretation that is confusing the issue. This is particularly true when discussing the meaning of the words themselves.

Therefore, it is important to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site serves as an accompaniment to the 2001 series, and also a resource on its own. The information is presented in a structured way that makes it easy to navigate and understand.

The site defines terms like common ancestor, gradual process and 에볼루션 룰렛 adaptation. These terms help frame the nature and significance of evolution to other concepts in science. The website provides a summary of the manner that evolution has been examined. This information can be used to dispel the myths that have been propagated by the creationists.

It is also possible to get a glossary of terms used in evolutionary biology. These terms include:

Adaptation is the tendency of heritable traits to be better suited to an environment. This is the result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adapted characteristics to survive and reproduce.

Common ancestor (also called common ancestor): The most recent ancestor that is shared by two or more species. The common ancestor 에볼루션 게이밍 can be identified by analyzing the DNA of the species.

Deoxyribonucleic Acid: A massive biological molecular that contains the information needed for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, 에볼루션 슬롯코리아 (click4r.com) called chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is the relationship between two species where evolution of one species are influenced evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey or the parasite and the host.

Origins

Species (groups that can interbreed) develop through a series of natural changes in their offspring's traits. The causes of these changes are various factors, including natural selection, gene drift and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, like climate change or competition for food and habitat can impede or accelerate the process.

The Evolution site follows the evolution of various animal and plant groups and focuses on major changes in each group's history. It also examines the evolutionary origin of humans which is particularly important for students to know.

Darwin's Origin was written in 1859, when only a few antediluvian fossils of human beings had been discovered. The famous skullcap, along with the bones that accompanied it 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 first published in 1858, one year after the publication of the first edition of The Origin.

While the site is focused on biology, it also contains a wealth of information on geology and paleontology. Among the best features on the site are a series of timelines that show how geological and climatic conditions have changed over time, and a map of the distribution of a few fossil groups listed on the site.

While the site is a companion to a PBS television series, it also stands on its own as a great source for teachers and students. The site is well organized and provides clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler's experiments with guppies, which illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life has resulted in an array of animals, plants and insects. Paleobiology is the study of these creatures in their geographical context and offers a number of advantages over the modern observational and research methods for analyzing evolutionary phenomena. Paleobiology is able to study not only processes and events that take place regularly or over time but also the relative abundance and distribution of different groups of animals across geological time.

The Web site is divided into several optional paths to learning evolution, including "Evolution 101," which takes the user on a linear path through the scientific process and the evidence that supports the theory of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thinking.

Each of the main sections on the Evolution website is equally well-developed, with materials that support a variety levels of curriculum and 바카라 에볼루션게이밍; Read A lot more, teaching methods. The site offers a wide array of multimedia and interactive resources, including video clips, animations and virtual labs, in addition to its general textual content. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation within the large web site.

The page "Coral Reef Connections", for example, provides an overview of the relationships between corals and interactions with other organisms and then zooms in to one clam that can communicate with its neighbors and respond to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and multimedia pages gives a good introduction to many topics in evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis which is a crucial method to understand evolutionary changes.

Evolutionary Theory

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

One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that offers both the depth and breadth of its educational resources. The site offers a variety of interactive learning modules. It also features a "bread crumb structure" that assists students in moving away from the cartoon-like style of Understanding Evolution and onto elements of this vast website that are closely linked to the realms of research science. Animation that introduces the concept of genetics links to a page that highlights John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.

Another helpful resource is the Evolution Library on this web website, which includes an extensive library of multimedia resources related to evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives set out in biology standards. It contains seven videos specifically designed for classroom use. These can be streamed or purchased as DVDs.

Many important questions remain in the midst of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is especially true for human evolution, where it has been difficult to reconcile the notion that the physical traits of humans were derived from apes, and the religious beliefs that hold that humans are unique in the universe and has a special place in creation with a soul.

There are a myriad of other ways evolution could occur, with natural selection as the most popular theory. However scientists also study other types of evolution such as genetic drift, mutation, and sexual selection, among others.

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