Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution persist. Pop science nonsense has led many people to think that biologists don't believe in evolution.
This rich Web site, which is a companion to the PBS program, provides teachers with materials which support evolution education while avoiding the types of misconceptions that hinder it. It's laid out in the "bread crumb" format to aid in navigation and orientation.
Definitions
Evolution is a complicated and challenging subject to teach well. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. This is especially true when it comes to debates about the definition of the word itself.
It is therefore crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The website is a companion to the series that first aired in 2001, but it also functions as an independent resource. The material is presented in a nested manner which aids navigation and orientation.
The site defines terms such as common ancestor and the gradual process. These terms help frame the nature of evolution as well as its relationship to other scientific concepts. The site then offers an overview of how the concept of evolution has been vetted and verified. This information can help dispel myths that are created 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 hereditary traits to become more adaptable to a specific environment. This is the result of natural selection, which happens when organisms that have more adaptable traits are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor: The most recent common ancestor of two or more distinct species. By analyzing the DNA from these species it is possible to identify the common ancestor.
Deoxyribonucleic Acid: A massive biological molecular that contains the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains known 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 are influenced evolutionary changes in the other. Coevolution can be observed through the interaction between predator and prey,

Origins
Species (groups that can crossbreed) develop through a series natural changes in their offspring's traits. The changes can be triggered by a variety of factors that include natural selection, genetic drift, and gene pool mixing. The development of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food or habitat can slow or speed up the process.
The Evolution site traces the emergence of a number of different species of plants and animals over time with a focus on the key shifts that occurred throughout each group's history. It also explores human evolution, which is a topic that is of particular interest for students.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The most famous among them was the skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was a year before the first edition of the Origin was published, it's extremely unlikely that Darwin had ever heard of it.
While the site focuses on biology, it also offers a lot of information on geology and paleontology. Among the best features on the site are a series of timelines that illustrate how climatic and geological conditions changed over time, and an outline of the distribution of some fossil groups that are featured on the site.
The site is a companion to the PBS TV series but it could be used as a source for teachers and students. The site is well-organized and offers clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features of the museum website. These hyperlinks make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler's experiments with guppies that illustrate the importance ecology in evolutionary theory.
Diversity
The evolution of life has resulted in an array of plants, animals and insects. Paleobiology, the study of these creatures within their natural environment, has many advantages over modern observational or research methods for exploring evolutionary processes. Paleobiology focuses on not only the process and events that occur frequently or over time, but also the relative abundance and distribution of different species of animals across geological time.
The site is divided up into several paths that can be chosen to study the subject of evolution. One of these paths, "Evolution 101," takes the viewer through the nature and evidence of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thinking.
Each of the other main sections of the Evolution site is equally well developed, 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 as well as general textual content. The content is presented in a nested bread crumb-like fashion that helps with navigation and orientation within the large Web site.
For instance the page "Coral Reef Connections" gives a brief overview of coral relationships and their interaction with other organisms. Then, it narrows down to a single clam that can communicate with its neighbors and respond to changes in the water conditions at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a broad variety of topics in evolutionary biology. The content also includes an overview of the significance of natural selectivity and

https://dg-Network.it) the concept of phylogenetics, an important method for understanding the evolution of changes.
Evolutionary Theory
For biology students,
에볼루션 무료 바카라 evolution is a key thread that binds all the branches of the field. A wide range of resources helps teachers teach about evolution across all life sciences.
One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of an Web site that provides the depth and the wide range of educational resources. The site has a variety of interactive learning modules. It also has an "bread crumb structure" that assists students in moving away from the cartoon style that is used in Understanding Evolution and onto elements on this large website more closely connected to the realms of research science. For instance an animation that introduces the concept of genetic inheritance links to a page highlighting John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.
Another useful resource is the Evolution Library on this Web site, which contains an extensive collection of multimedia assets related to evolution. The content is organized in the form of curriculum-based pathways that are in line with the learning objectives outlined in the standards for biology. It includes seven short videos designed specifically for classroom use, which can be streamed for free or purchased on DVD.
Evolutionary biology is an area of study that has many important questions, including what causes evolution and how quickly it takes place. This is particularly relevant to human evolution, where it has been difficult to reconcile the idea that the physical characteristics of humans derived from apes and religions that believe that humans are unique among living things and holds a a special place in creation, with a soul.
In addition there are a variety of ways in which evolution could occur with natural selection being the most widely accepted theory. Scientists also study other kinds such as genetic drift, and sexual selection.
Although many scientific fields of study have a conflict with literal interpretations in religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, while others haven't.
