에볼루션 바카라 - Teaching About Evolution

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

This rich website - companion to the PBS series offers teachers with resources that support evolution education and avoids the kinds of myths that undermine it. It's laid out in a "bread crumb" format to make navigation and orientation easier.

Definitions

It's difficult to teach evolution well. It is often misunderstood even by non-scientists, and even scientists are guilty of using an interpretation that is confusing the issue. This is particularly relevant to discussions about the meaning of the word itself.

As such, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The site is both an accompaniment to the 2001 series, but also a resource on its own. The content is presented in a nested manner that assists in navigation and orientation.

The site defines terms such as common ancestor, the gradual process, and adaptation. These terms help frame the nature of evolution as well as its relation to other concepts in science. The site then offers an overview of how the concept of evolution has been tested and validated. This information will help to dispel the myths that are created by the creationists.

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

Adaptation: The tendency for heritable traits to become better suitable to a particular setting. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less adapted traits to survive and reproduce.


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

Deoxyribonucleic Acid: A massive biological molecular that contains the information needed for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

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

Origins

Species (groups of individuals that are able to interbreed) change through a series of natural changes in the characteristics of their offspring. These changes are caused by a variety, including natural selection, genetic drift, and gene pool mixing. The development of a new species may take thousands of years, and the process may be slowed down or accelerated by environmental conditions such as climate change or competition for food or habitat.

The Evolution site traces through time the evolution of different species of plants and animals with a focus on major changes within each group's past. It also focuses on the human evolutionary roots and humans, a subject that is particularly important for students to know.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. simply click the following site of them was the infamous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap, which was first published in 1858, one year following the initial edition of The Origin.

The site is mostly an online biology resource however it also includes lots of information about geology and paleontology. The site offers numerous features that are particularly impressive, including an overview of how climate and geological conditions have changed over time. It also has maps that show the locations of fossil groups.

The site is a companion for the PBS TV series but it could be used as a resource by teachers and students. The site is well-organized and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features of the museum website. These hyperlinks make it easy to move 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 that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment and has many advantages over the current observational and experimental methods for analyzing evolutionary phenomena. Paleobiology can examine not only processes and events that happen frequently or over time, but also the relative abundance and distribution of various animal groups in space throughout geological time.

The website is divided into several paths that can be chosen to study the subject of evolution. One of the paths, "Evolution 101," guides the user through the nature and evidence of evolution. The path also examines myths about evolution and the background of evolutionary thinking.

Each of the other sections of the Evolution site is similarly developed, with materials that can be used to support a range of educational levels and pedagogical styles. The site offers a wide array of multimedia and interactive resources which include videos, animations, and virtual labs as well as general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the large Web site.

For example the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interaction with other organisms. Then, it narrows down to a single clam that can communicate with its neighbors and react to changes in the water conditions at the level of the reef. This page, as well as the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a wide range of topics in evolutionary biology. The material also provides an overview of the importance of natural selection and the concept of phylogenetic analysis which is a key tool in understanding evolutionary change.

Evolutionary Theory

For biology students the concept of evolution is a major thread that binds all the branches of the field. A vast collection of books helps in teaching evolution across all disciplines of life sciences.

One resource, 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 offers a range of interactive learning modules. It also has a nested "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely tied to the field of research science. An animation that introduces the concept of genetics, which links to a page highlighting John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.

Another helpful resource is the Evolution Library on this website, which includes an extensive multimedia library of assets related to evolution. The contents are organized into curriculum-based paths that parallel the learning objectives set out in the biology standards. 에볼루션게이밍 contains seven short videos that are designed for use in classrooms. These are available to stream or purchase as DVDs.

A number of important questions remain in the midst of evolutionary biology, including what triggers evolution and how fast it occurs. This is especially true for human evolution, where it's been difficult to reconcile the notion that the physical characteristics of humans were derived from apes and religions that believe that humanity is unique in the universe and has an enviable place in creation, with a soul.

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

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. While some religions have been able to reconcile their beliefs with the notions of evolution, other religions have not.
