Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution remain. People who have taken in popular science myths often assume that biologists claim they do not believe in evolution.

This site, a companion to the PBS program offers teachers resources that promote evolution education while avoiding the types of misconceptions that 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 challenging subject to teach well. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition which confuses it. This is especially true when discussing the meaning of the words themselves.

It is essential to define terms that are used in evolutionary biology. Understanding Evolution's website does this in a straightforward and useful way. The site is a companion to the show which first aired in 2001, but can also function as an independent resource. The material is organized in a manner that makes it easier to navigate and 에볼루션 무료체험 comprehend.

The site defines terms like common ancestor, gradual process and adaptation. These terms help to define the nature of evolution and its relationship to other scientific concepts. The site provides an overview of the manner that evolution has been tested. This information can be used to dispel myths that have been propagated by the creationists.

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

Adaptation: The tendency of hereditary traits to become more suitable to a particular setting. This is the result of natural selection. It occurs when organisms that have more adaptable traits are more likely survive and reproduce than those with less adaptable traits.

Common ancestor (also known as common ancestor): The most recent ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of those species.

Deoxyribonucleic Acid: A large biological molecular that contains the information needed for cell replication. The information is stored in nucleotide sequences, which are strung into long chains called chromosomes. Mutations are the source of new genetic information in cells.

Coevolution: 에볼루션 코리아 (read this post from 123.60.103.97) A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution are the interactions between predator and prey, 에볼루션 게이밍 or host and parasite.

Origins

Species (groups that can interbreed), evolve through a series natural changes in the traits of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift and 에볼루션 룰렛 mixing of the gene pool. The development of new species can take thousands of years. Environmental circumstances, such as climate changes or competition for food or habitat, can slow or accelerate the process.

The Evolution site tracks through time the evolution of different animal and plant groups with a focus on major changes in each group's history. It also focuses on the human evolutionary roots, a topic that is particularly important for students to understand.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans had been found. The famous skullcap, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. Although the skullcap was not published until 1858, a year before the first edition of the Origin was published, it's highly unlikely that Darwin had seen or heard of it.

The site is primarily an online biology resource however it also includes many details on geology and paleontology. The most impressive features of the Web site are a set of timelines that illustrate how climatic and geological conditions have changed over time and an interactive map of the distribution of a few fossil groups listed on the site.

While the site is a companion piece to the PBS television show however, it can stand on its own as an excellent source for teachers and students. The site is extremely well-organized and has clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum Web site. These hyperlinks make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler's experiments with guppies, which illustrate the importance 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 geological context offers many advantages over modern observational or research methods of studying evolutionary phenomena. In addition to examining processes and events that occur regularly or over a long period of time, paleobiology is able to examine the relative abundance of different kinds of organisms as well as their distribution throughout the course of geological time.

The site is divided up into several routes that can be taken to learn about evolution. One of these paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The path also examines myths about evolution, as well as the history of evolutionary thought.

Each of the other major sections of the Evolution site is similarly constructed, with materials that can support a variety of curriculum levels and pedagogical styles. In addition to the general textual content, the site offers an array of multimedia and interactive content including videos, animations, and virtual laboratories. The breadcrumb-like organization of the content aids in navigation and orientation on the vast web site.

The page "Coral Reef Connections" For instance, it provides a comprehensive overview of coral relationships, 에볼루션 무료 바카라 their interaction with other organisms, and then zooms in to one clam that is able communicate with its neighbors and respond to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, offers a great introduction to the many areas of evolutionary biology. The content includes an explanation of the significance of natural selectivity and the concept phylogenetics analysis which is a crucial tool for understanding evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A vast collection of books helps in teaching evolution across all disciplines of life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and breadth in its educational resources. The site has a wide array of interactive learning modules. It also features a nested "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely tied to the world of research science. Animation that introduces the concept of genetics is linked to a page highlighting John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.

The Evolution Library on this website has a huge multimedia library of materials that deal with evolution. The contents are organized into curriculum-based paths that parallel the learning objectives set out in the standards for biology. It contains seven short videos that are designed for use in classrooms. They can be viewed online or purchased as DVDs.

Evolutionary biology remains an area of study that has many important questions, such as what triggers evolution and how quickly it happens. This is especially relevant to human evolution, which has made it difficult to reconcile the idea that the physical traits of humans derived from apes with religions that believe that humans are unique among living things and holds a an enviable place in creation, with soul.

There are also a number of other ways evolution can take place including natural selection, which is the most widely accepted theory. However scientists also study other types of evolution such as mutation, genetic drift, and sexual selection, among other things.

While many scientific fields of study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been a subject of intense debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, other religions aren't.
