Evolution Site - Teaching About Evolution

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

This site, which is a companion to the PBS series offers teachers with resources that promote evolution education and avoid the kinds of misinformation that can undermine it. It's laid out in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to properly teach evolution. Many non-scientists are unable to grasp the concept and some scientists employ a definition that confuses it. This is particularly relevant to discussions on the nature of the word.

It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful way. The website is a companion to the show that premiered in 2001, but is also an independent resource. The content is presented in a nested manner that assists in navigation and orientation.

The site defines terms such as common ancestor and the gradual process. These terms help to define the nature of evolution as well as its relationship to other scientific concepts. The website provides a summary of the way in which evolution has been examined. This information can be used to dispel myths that have been engendered by creationists.

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

Adaptation: 에볼루션 사이트 The tendency for heritable traits to become better suitable to a particular setting. This is a result of natural selection, which happens when organisms that are more adaptable characteristics are more likely to survive and reproduce than those with less adaptable characteristics.

Common ancestor (also known as common ancestor) The most recent ancestor shared by two or more species. By analyzing the DNA from these species it is possible to identify the common ancestor.

Deoxyribonucleic Acid: 에볼루션 무료체험 A huge biological molecular that contains the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be observed in the interactions between predator and prey, or parasite and hosts.

Origins

Species (groups that can interbreed) develop through a series of natural changes in the traits of their offspring. The changes can be triggered by a variety of factors that include natural selection, genetic drift, and mixing of gene pools. The evolution of a new species could take thousands of years and the process can be slowed down or accelerated due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site traces the emergence of various groups of animals and 에볼루션 plants over time with a focus on the key changes that took place in the evolution of each group's history. It also focuses on the evolutionary history of humans, a topic that is particularly important for students to know.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap when it was published in 1858, 에볼루션 바카라 무료 a year following the initial edition of The Origin. Origin.

While the site is focused on biology, it also includes a good deal of information about geology and paleontology. The website 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.

Although the site is a companion to the PBS television series, it also stands on its own as a valuable source for teachers and students. The site is extremely well organized and provides clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated components of the museum's Web site. These hyperlinks help users move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are hyperlinks to John Endler's research with Guppies, which demonstrate 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 is the study of these creatures within their geological context offers many advantages over modern observational or experimental 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 in space over the geological time.

The site is divided into various options to study the subject of evolution. One of the paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The course also focuses on misconceptions about evolution, and the background of evolutionary thinking.

Each of the other sections of the Evolution site is equally well constructed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. The site offers a wide array of interactive and multimedia content which include videos, animations, and virtual laboratories in addition to general textual content. The content is presented in a nested bread crumb style that facilitates navigation and orientation within the large Web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships and interactions with other organisms and then zooms in to one clam that is able to communicate with its neighbours and respond to changes in the conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, 에볼루션 바카라 무료 offers a great introduction to many topics in evolutionary biology. The information also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is an important tool for understanding the evolution of changes.

Evolutionary Theory

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

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that offers both depth as well as wide range of educational resources. The site features a wealth of interactive learning modules. It also has a "bread crumb structure" that assists students in moving away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely related to the realms of research science. For example an animation that introduces the concept of genetic inheritance links to a page highlighting John Endler's experiments in artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website contains a large multimedia library of assets related to evolution. The content is organized according to curricula-based pathways that correspond to the learning objectives set out in the standards for biology. It includes seven short videos designed specifically for use in classrooms, and can be streamed at no cost or purchased on DVD.

Evolutionary biology is a field of study with a lot of important questions, including the causes of evolution and how quickly it takes place. This is especially true for the evolution of humans, where it was difficult to reconcile religious beliefs that humanity has a unique place in creation and a soul, with the notion that our physical traits originated from Apes.

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

Although many scientific fields of study are in conflict with literal interpretations found in religious texts, evolution biology has been a source of intense debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
