Evolution Site - Teaching About Evolution

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

This rich Web site - companion to the PBS series offers teachers with resources that promote evolution education and help avoid the kinds of misconceptions that make it difficult to understand. It's organized in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

It's difficult to teach evolution well. It is often misunderstood by non-scientists and even some scientists are guilty of using definitions that confuse the issue. This is especially relevant to debates about the meaning of the word itself.

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 에볼루션 helpful way. The site is a companion site to the series that first aired in 2001, 에볼루션 사이트 but it can also function as an independent resource. The content is presented in a nested fashion that aids navigation and orientation.

The site defines terms such as common ancestor and the gradual process. These terms help frame the nature of evolution and its relation to other concepts in science. The website provides a summary of the way the concept of evolution has been tested. This information can be used to dispel the myths that have been propagated by creationists.

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

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

Common ancestor [Redirect Only] (also called common ancestor): The most recent ancestor 에볼루션 사이트 that is shared by two or more species. The common ancestor can be identified through analyzing the DNA of those species.

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

Coevolution is a relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Coevolution can be seen in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups that can interbreed), evolve through a series natural changes in the traits of their offspring. The changes can be triggered by a variety of causes such as natural selection, genetic drift and mixing of gene pools. The development of new species can take thousands of years. Environmental conditions, such as climate change or competition for food or habitat, can slow or accelerate the process.

The Evolution site tracks the evolution of various species of plants and animals over time and focuses on the most significant shifts that occurred throughout the evolution of each group's history. It also focuses on human evolution as a subject of particular importance to students.

Darwin's Origin was written in 1859, when only a handful of antediluvian fossils of humans had been found. The famous skullcap, with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was published in 1858, one year following the initial edition of The Origin.

While the site is focused on biology, it includes a good deal of information about geology and paleontology. Among the best features of the Web site are a timeline of events that show how geological and climatic conditions have changed over time, as well as an outline of the geographical distribution of some fossil groups listed on the site.

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

Diversity

The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology, the study of these creatures within their natural environment, has many advantages over the current observational or experimental methods for exploring evolutionary phenomena. Paleobiology is able to study not just the processes and events that occur frequently or 에볼루션 무료 바카라 over time, but also the distribution and frequency of various animal groups in space throughout the geological time.

The site is divided into several optional ways to learn about evolution which include "Evolution 101," which takes the viewer on a line through the science of nature and the evidence to support the theory of evolution. The path also reveals common misconceptions about evolution as well as the history of evolutionary thought.

Each of the other main sections of the Evolution site is similarly constructed, with materials that support a variety of educational levels and pedagogical styles. The site includes a variety of interactive and multimedia resources which include animations, video clips and virtual laboratories as well as general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the vast Web site.

For example, the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interactions 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 that take place at the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to the broad spectrum of topics in evolutionary biology. The content includes a discussion on the importance of natural selection and the concept of phylogenetics as a key tool for understanding evolutionary change.

Evolutionary Theory

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

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that provides depth as well as wide range of educational resources. The site features a wealth 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 huge site that are closer to the field of research science. An animation that introduces the concept of genetics is linked to a page that highlights John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.

Another useful resource is the Evolution Library on this web site, which has an extensive multimedia library of assets that are related to evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives outlined in the biology standards. It includes seven short videos specifically designed for classroom use, which can be streamed at no cost or purchased on DVD.

Many important questions remain at the core of evolutionary biology, including the factors that trigger evolution and 바카라 에볼루션사이트; Https://Www.Bitsdujour.Com/Profiles/M35YPR, how fast it occurs. This is particularly relevant for humans' evolution which was a challenge to reconcile religious beliefs that humanity has a special place in the creation and a soul, with the idea that innate physical traits originated from Apes.

There are also a number of other ways in which evolution can occur and natural selection being the most widely accepted theory. Scientists also study other kinds such as genetic drift, 에볼루션 바카라 and sexual selection.

While many fields of scientific inquiry have a conflict with the literal interpretations of religious texts, evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, other religions haven't.
