Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, there are still a lot of misconceptions about evolution. People who have taken in pop science nonsense often assume that biologists do not believe in evolution.

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

Definitions

Evolution is a complex and difficult subject matter to teach well. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. This is particularly relevant to discussions about the nature of the word.

Therefore, it is important to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site is a companion site to the show that premiered in 2001, but it also functions as an independent resource. The information is presented in an organized manner that makes it simpler to navigate and understand.

The site defines terms like common ancestor, gradual process and adaptation. These terms help to define the nature of evolution and its relationship to evolution with other scientific concepts. The website provides a summary of the way in which evolution has been tested. This information can help dispel myths that are created by the creationists.

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

Adaptation: The tendency of heritable characteristics to become more suited to a particular environment. This is due to natural selection, 에볼루션 룰렛 which happens when organisms with better adapted traits are more likely to survive and 에볼루션 룰렛 reproduce than those with less adapted traits.

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

Deoxyribonucleic acid: A huge biological molecule that contains information required for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the source of new genetic information within cells.

Coevolution is a relationship between two species where 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 natural changes in the traits of their offspring. The changes can be triggered by a variety of factors, including natural selection, genetic drift, and mixing of genes. The evolution of new species could take thousands of years. Environmental conditions, like climate change or competition for food and habitat can slow or speed up the process.

The Evolution site tracks the development of a variety of animal and plant groups through time and focuses on the most significant shifts that occurred throughout each group's history. It also focuses on human evolution, which is a topic that is particularly important for students.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of human beings had been discovered. The most famous among them was the skullcap and associated bones found 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 knew about the skullcap, which was first published in 1858, one year following the initial edition of The Origin. Origin.

The site is primarily an online biology resource however it also includes a lot of information on geology and paleontology. The Web site has several aspects that are quite impressive, including a timeline of how climate and geological conditions have changed over time. It also features a map showing the distribution of fossil groups.

While the site is a companion to the PBS television series, it also stands on its own as an excellent source for teachers and students. The site is extremely well-organized and 에볼루션 바카라 무료 has clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly, there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in an array of plants, animals and insects. Paleobiology is the study of these creatures within their geological context and has a number of advantages over the modern observational and research methods in its exploration of evolutionary processes. Paleobiology focuses on not only the process and events that happen frequently or over time, but also the distribution and frequency of different species of animals in space over the course of the geological time.

The website is divided into various ways to learn about evolution which include "Evolution 101," which takes the viewer on a line through the scientific process and 에볼루션사이트 the evidence supporting the theory of evolution. The path also examines myths about evolution, 에볼루션 블랙잭 and also the history of evolutionary thinking.

Each of the other major 에볼루션사이트 sections of the Evolution site is equally created, with resources that can support a variety of educational levels and pedagogical styles. In addition to the general textual content, the site offers an extensive selection of multimedia and interactive content like video clips, animations, and virtual laboratories. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the vast web site.

For example, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms. It then narrows down to a single clam that can communicate with its neighbours and respond to changes in the water conditions that occur at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to many topics in evolutionary biology. The material includes an overview of the importance of natural selection and the concept of phylogenetics analysis which is a crucial tool to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that connects all branches of biology. A rich collection supports teaching evolution across all life science disciplines.

One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that offers both depth and a variety of educational resources. The site features a wealth of interactive learning modules. It also features an embedded "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this huge site that are more closely tied to the world of research science. For instance an animation that introduces the idea of genetic inheritance connects to a page that highlights John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

Another useful resource is the Evolution Library on this web website, which includes an extensive multimedia library of items that are related to evolution. The contents are organized into curriculum-based paths that parallel the learning goals established in the biology standards. It includes seven short videos designed for use in classrooms. These can be streamed or purchased as DVDs.

A number of important questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is especially true for humans' evolution where it was a challenge to reconcile religious beliefs that humanity has a unique place in the creation and a soul with the notion that our physical traits originated from the apes.

There are also a number of other ways evolution can occur and natural selection being the most well-known theory. Scientists also study different types like mutation, genetic drift, and 에볼루션사이트 sexual selection.

While many fields of scientific study conflict with the literal interpretations of religious texts, evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, but others haven't.
