Evolution Site Tips That Will Change Your Life

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution persist. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.

This rich Web site, which is a complement to the PBS program that provides teachers with resources that promote evolution education, while avoiding the kinds of misconceptions that can hinder it. It's organized in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

It's difficult to properly teach evolution. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. This is particularly true when discussing the meaning of the words themselves.

Therefore, it is essential to define terms that are used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful way. The site is a companion to the series that first aired in 2001, but it also functions as an independent resource. The content is presented in a way which aids navigation and orientation.

The site defines terms like common ancestor, gradual process and so on. These terms help define the nature and relationship of evolution with other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and verified. This information can help dispel the myths that are created by the creationists.

You can also access a glossary which contains terms used in evolutionary biology. These terms include:

Adaptation is the process of changing heritable traits to become more suited to the environment. This is a result of natural selection. Organisms with more adaptable traits are more likely than those with less-adapted characteristics to survive and reproduce.

Common ancestor: 에볼루션 사이트 The most recent common ancestor of two or more different species. By analyzing DNA from these species it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular that contains the information required for cell replication. The information is stored in a sequence of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the basis for new genetic information within cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey or host and parasite.

Origins

Species (groups that can interbreed) develop through a series of natural changes in the traits of their offspring. These changes are caused by a variety of causes, including natural selection, genetic drift, and mixing of gene pools. The evolution of new species can take thousands of years. Environmental conditions, like changes in the climate or competition for food or habitat can impede or accelerate the process.

The Evolution site traces the emergence of various species of plants and animals over time with a focus on the key transitions that occurred in the evolution of each group's history. It also examines the evolution of humans as a subject that is of particular interest to students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. The famous skullcap, along with the bones associated with it, 에볼루션 바카라 무료 was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded 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 set of timelines that show how climatic and geological conditions changed over time, as well as an outline of the distribution of a few fossil groups that are featured on the site.

Although the site is a companion to the PBS television series however, it can stand on its own as an excellent resource 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 links facilitate the transition 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 demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has resulted in a variety of plants, animals, and insects. Paleobiology, the study of these creatures within their geological context is a superior method of study over modern observational or experimental methods for studying evolutionary phenomena. In addition to exploring processes and events that occur frequently or over a long period of time, paleobiology allows to study the relative abundance of various kinds of organisms as well as their distribution throughout geological time.

The site is divided up into various routes that can be taken to learn about evolution. One of the paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The path also explores common misconceptions about evolution and the evolution of thought.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that are suited to a variety of curriculum levels and teaching styles. The site has a range of interactive and multimedia resources that include video clips, 에볼루션 무료 바카라 animations and virtual laboratories, in addition to its general textual content. The content is presented in a nested bread crumb fashion that aids navigation and 에볼루션 바카라 사이트 orientation on the Web site.

For example the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms. It then narrows down to a single clam that can communicate with its neighbors and react to changes in water conditions at the level of the reef. This page, along with the other multidisciplinary interactive and multimedia pages provides an excellent introduction to many topics in evolutionary biology. The material also provides an explanation of the role of natural selection and the concept of phylogenetic analysis, 에볼루션 바카라 which is a key method to understand evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A rich collection supports teaching evolution across the life science disciplines.

One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides depth and breadth in its educational resources. The site features a wealth of interactive learning modules. It also features an "bread crumb structure" that assists students in moving away from the cartoon style of Understanding Evolution and onto elements on this large website more closely linked to the realms of research science. For example an animation that explains the notion of genetic inheritance leads to a page that focuses on John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized into curricula-based paths that correspond to the learning objectives set out in biology standards. It includes seven short videos designed specifically for use in classrooms, and can be streamed for free or purchased on DVD.

Evolutionary biology remains a field of study that poses many important questions, such as what triggers evolution and how quickly it takes place. This is particularly true for humans' evolution where it was a challenge to reconcile religious beliefs that humanity has a unique position in the universe and a soul, with the notion that our physical traits were derived from Apes.

In addition there are a myriad of ways in which evolution could occur and natural selection is the most widely accepted theory. However, scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among other things.

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