Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution persist. People who have absorbed popular science myths often assume that biologists don't believe in evolution.

This site, which is a companion to the PBS series - provides teachers with materials that support evolution education and help avoid the kinds of myths that hinder it. It's laid out in a "bread crumb" format to make navigation and orientation easier.

Definitions

It's difficult to teach evolution well. People who are not scientists often have a difficult time understanding the subject, and 에볼루션게이밍 some scientists even use a definition that confuses it. This is particularly relevant to debates about the nature of the word.

As such, it is important to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site is a companion site to the show which first aired in 2001, but can also function as an independent resource. The material is presented in a nested manner that aids navigation and orientation.

The site defines terms like common ancestor and the gradual process. These terms help frame the nature and relationship of evolution with other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and validated. This information can help dispel the myths created by creationists.

It is also possible to find a glossary of terms that are used in evolutionary biology. These terms include:

Adaptation is the tendency of hereditary traits to become more suited to the environment. This is the result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adaptable traits to reproduce and survive.

Common ancestor: 에볼루션 바카라 무료 The most recent common ancestor of two or more distinct species. By analyzing DNA from these species it is possible to identify the common ancestor.

Deoxyribonucleic acid: A huge biological molecule that contains the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are responsible for 에볼루션 바카라 체험 the creation of new genetic information inside cells.

Coevolution is a relationship between two species in which 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 crossbreed) change by a series of natural variations in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, like changes in the climate or competition for food resources and habitat can impede or accelerate the process.

The Evolution site follows the evolution of different groups of animals and plants, focusing on major transitions within each group's past. It also focuses on human evolution and is a subject of particular importance to students.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The famous skullcap, with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just a year before the first edition of the Origin appeared, it is extremely unlikely that Darwin had seen or heard of it.

While the site is focused on biology, it includes a good deal of information about geology and paleontology. The most impressive features on the site are a series of timelines which show how geological and climatic conditions have changed over time as well as an outline of the distribution of a few of the fossil groups featured on the site.

Although the site is a companion to the PBS television show, it also stands on its own as a great resource for teachers and 에볼루션 바카라 무료체험 students. The site is well-organized and offers clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. In particular, there are links to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants and insects. Paleobiology is the study of these creatures within their geological context and has a number of advantages over modern observational and experimental methods of examining evolutionary processes. Paleobiology can examine not only the process and events that take place frequently or over time, but also the distribution and frequency of different groups of animals across the geological time.

The Web site is divided into a variety of paths to learning evolution that include "Evolution 101," which takes the viewer on a line through the nature of science and the evidence to support the theory of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thought.

Each of the other sections of the Evolution site is equally well developed, with materials that can be used to support a range of curriculum levels and pedagogical styles. The site includes a variety of interactive and multimedia content that include videos, animations, and virtual labs as well as general textual content. The breadcrumb-like organization of the content helps with navigation and orientation on the massive 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 zooms in to one clam, which is able to communicate with its neighbors and react to changes in conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a wide range of topics in evolutionary biology. The content also includes a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a crucial tool for understanding the evolution of change.

Evolutionary Theory

For biology students the concept of evolution is a major thread that binds all branches of the field. A rich collection supports teaching evolution across the disciplines of life sciences.

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that provides depth and broadness in terms of educational resources. The site has a variety of interactive learning modules. It also features an "bread crumb structure" that assists students in moving away from the cartoon-like style that is used in Understanding Evolution and 에볼루션 바카라 무료체험 onto elements on this site that are more closely connected to the worlds of research science. For example an animation that explains the idea of genetic inheritance connects to a page highlighting John Endler's experiments in artificial selection with guppies in native ponds of Trinidad.

The Evolution Library on this website is a vast multimedia library of assets related with evolution. The content is organized according to curricula-based paths that correspond to the learning goals set forth in the standards for 에볼루션 바카라 무료체험 biology. It contains seven videos intended for 에볼루션 코리아코리아 (https://radiospot61.werite.Net/) use in the classroom. They are available to stream or purchase as DVDs.

A number of important questions remain at the core of evolutionary biology, such as the factors that trigger evolution and how fast it occurs. This is particularly true in the case of human evolution where it was a challenge to reconcile religious beliefs that held that humans have a distinct place in the creation and a soul with the notion that our physical traits evolved from Apes.

There are also a number of other ways in which evolution can take place and natural selection being the most popular theory. Scientists also study different types such as mutation, genetic drift and sexual selection.

While many fields of scientific inquiry have a conflict with literal interpretations of the Bible, evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions have not.
