Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, misconceptions persist about the evolution. People who have taken in pop science nonsense often assume that biologists claim they don't believe in evolution.

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

Definitions

Evolution is a complex and challenging subject to teach effectively. It is often misunderstood by non-scientists, and even scientists are guilty of using a definition that confuses the issue. This is especially relevant when it comes to the nature of the words themselves.

It is therefore essential to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The site is a companion to the show that premiered in 2001, but can also function as an independent resource. The content is presented in a structured manner that makes it simpler to navigate and understand.

The site defines terms such as common ancestor and the gradual process. These terms help to define the nature and significance of evolution to other concepts in science. The website then provides an overview of how the concept of evolution has been researched and confirmed. This information will help to dispel the myths that are created by the creationists.

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

Adaptation: 에볼루션 블랙잭 The tendency for hereditary traits to become more suitable to a particular setting. This is a result of natural selection, which occurs when organisms that are better-adapted traits are more likely to survive and reproduce than those with less adapted traits.

Common ancestor (also known as common ancestor) The most recent ancestral ancestor shared by two or more species. By analyzing the DNA from these species, it is possible to determine the common ancestor.

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

Coevolution is a relation between two species where evolution of one species influence evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey, 에볼루션바카라 or the parasite and the host.

Origins

Species (groups which can interbreed), evolve by a series of natural variations in the traits of their offspring. The causes of these changes are 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 could be slowed down or accelerated by environmental conditions such as climate change or competition for food or habitat.

The Evolution site traces the emergence of various species of plants and animals over time with a focus on the key changes that took place in the history of each group. It also focuses on human evolution and is a subject of particular importance for students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, one year after the publication of the first edition of The Origin. Origin.

While the site focuses on biology, it also offers a lot of information about geology as well as paleontology. Among the best features of the website are a timeline of events which show the way in which climatic and geological conditions changed over time, as well as an outline of the distribution of some of the fossil groups featured on the site.

Although the site is a companion piece to a PBS television series but it also stands on its own as a valuable resource for teachers and students. The site is extremely well organized and provides clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. These hyperlinks make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular there are links to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to many species of animals, plants and insects. Paleobiology is the study of these creatures in their geographical context and offers a number of advantages over the current observational and experimental methods of examining evolutionary phenomena. Paleobiology can examine not only processes and events that take place regularly or over time but also the relative abundance and distribution of various animal groups in space throughout geological time.

The site is divided into various routes that can be taken to study the subject of evolution. One of these paths, "Evolution 101," guides the user through the evolution of nature and the evidence of evolution. The course also focuses on common misconceptions about evolution and the history of evolutionary thought.

Each of the other sections of the Evolution site is equally constructed, with materials that can support a variety of curriculum levels and pedagogical styles. The site has a range of interactive and 에볼루션 무료체험 multimedia resources which include video clips, animations and virtual laboratories, in addition to its general textual content. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the vast web site.

The page "Coral Reef Connections", for 에볼루션 블랙잭 example, provides an overview of the coral's relationships and their interactions with other organisms and zooms in to one clam that is able communicate with its neighbours and respond to changes in the conditions of the water that occur at the reef level. This page, 에볼루션 룰렛 as well as the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is a crucial tool in understanding evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A wide range of resources helps teachers teach about evolution across all life sciences.

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 에볼루션코리아 breadth of its educational resources. The site offers a variety of interactive learning modules. It also has a "bread crumb structure" that assists students in moving away from the cartoon-like style of Understanding Evolution and onto elements on this large website more closely linked to the fields of research science. For example an animation that introduces the concept of genetic inheritance links to a page that highlights John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad.

The Evolution Library on this website contains a large multimedia library of resources that are associated to evolution. The content is organized according to curricula-based paths that correspond to the learning goals set forth in biology standards. It contains seven videos designed for use in classrooms. These can be streamed or purchased as DVDs.

A number of important questions remain at the core of evolutionary biology, such as what triggers evolution and how fast it occurs. This is especially true for humans' evolution, where it was difficult to reconcile religious beliefs that held that humanity has a unique place in creation and a soul, 에볼루션 블랙잭 with the notion that human beings have innate physical traits originated from the apes.

In addition there are a variety of ways that evolution could occur with natural selection being the most popular theory. However scientists also study different types of evolution such as genetic drift, mutation, and sexual selection, among others.

Although many scientific fields of study are in conflict with literal interpretations in religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, others haven't.
