Evolution Site - Teaching About Evolution

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

This rich Web site - companion to the PBS series offers teachers with resources that promote evolution education and help avoid the kinds of misinformation that can hinder it. It's laid out in a "bread crumb" format to aid in navigation and orientation.

Definitions

Evolution is a complex and difficult subject to teach well. It is often misunderstood even by non-scientists, and even some scientists use a definition that confuses the issue. This is especially true when discussing the nature of the words themselves.

It is therefore crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient manner. The website is a companion to the show that premiered in 2001, but can also function as an independent resource. The content is presented in an organized way that makes it easy to navigate and understand.

The site defines terms like common ancestor, gradual process, and adaptation. These terms help to define the nature of evolution as well as its relation to other concepts in science. The website then provides an overview of how the concept of evolution has been researched and confirmed. This information can be used to dispel misconceptions that have been engendered by the creationists.

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

Adaptation: The tendency for heritable traits to become better adaptable to a specific environment. This is a result of natural selection. Organisms that have better-adapted traits 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 can be identified through analyzing the DNA of those species.

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

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

Origins

Species (groups that can interbreed), evolve through a series natural changes in their offspring's traits. These changes can be caused by many factors, such as natural selection, 에볼루션바카라 gene drift, and mixing of the gene pool. The development of a new species may take thousands of years and the process can be slowed down or speeded up by environmental factors like climate change or the competition for food or habitat.

The Evolution site tracks through time the evolution of different species of plants and animals with a focus on major changes in each group's history. It also focuses on the human evolutionary roots which is particularly important for students to understand.

Darwin's Origin was published in 1859, at a time when only a few antediluvian fossils of humans were discovered. Among them was the famous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, one year before the first edition of the Origin was published, it's highly unlikely that Darwin had seen or 에볼루션 무료 바카라 heard of it.

While the site focuses on biology, it also contains a wealth of information on geology and paleontology. Among the best features of the website are a timeline of events which show how geological and climatic conditions changed over time, and an interactive map of the distribution of some fossil groups that are featured on the site.

The site is a companion for the PBS TV series but it could also be used as an educational source for teachers and students. The site is well-organized and 에볼루션 무료체험 offers clear links to the introduction content of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features on the museum's website. These links make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. Particularly 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 produced an array of animals, 에볼루션 바카라 무료체험 plants and 에볼루션 insects. Paleobiology is the study of these creatures within their geographical context and offers many advantages over modern observational and experimental methods of examining evolutionary processes. Paleobiology can examine not only processes and events that occur regularly or over time, but also the distribution and frequency of different groups of animals in space over the course of the geological time.

The site is divided into several options to study the subject of evolution. One of these paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also explores misconceptions about evolution, as well as the history of evolutionary thinking.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that support a variety educational levels and teaching styles. The site offers a wide array of multimedia and interactive resources, including video clips, animations and virtual labs as well as general textual content. The breadcrumb-like structure of the content assists with navigation and orientation on the vast Web site.

For instance the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interaction with other organisms. Then, it concentrates on a specific clam that is able to 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 spectrum of topics in evolutionary biology. The content also includes an overview of the significance of natural selectivity and the concept phylogenetics analysis which is a crucial method for understanding the evolution of change.

Evolutionary Theory

For biology students evolution is a crucial thread that connects all the branches of the field. A wide range of resources can help teachers teach about evolution across the life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both depth and breadth in its educational resources. The site features a wealth of interactive learning modules. It also has an embedded "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this huge site that are more closely linked to the field of research science. Animation that introduces the concept of genetics links to a page highlighting John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized according to curricula-based pathways that correspond to the learning objectives outlined in the standards for biology. It contains seven videos that are designed for classroom use. They are available to stream or purchase as DVDs.

A number of important questions remain at the heart of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is particularly applicable to human evolution which has made it difficult to reconcile that the innate physical characteristics of humans evolved from apes, and the religious beliefs that claim that humans are unique among living things and has an enviable place in creation, with soul.

There are a myriad of other ways in which evolution could occur and natural selection being the most well-known theory. However, scientists also study other kinds of evolution, such as mutation, 에볼루션바카라 genetic drift and sexual selection, among others.

Many fields of inquiry have a conflict with the literal interpretations of religious texts evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolution, 에볼루션 카지노 사이트바카라 (my-social-box.com) but others haven't.
