Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation 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 offers teachers resources that support the evolution of education while avoiding the types of misconceptions that can undermine it. It's arranged in a nested "bread crumb" format to make it easy for 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 that confuses it. This is particularly relevant when it comes to the nature of the words themselves.
It is essential to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site is a companion to the show that premiered in 2001, but also functions as an independent resource. The material is presented in an organized way that makes it easy to navigate and comprehend.
The site defines terms like common ancestor (or common ancestor), gradual process, and adaptation. These terms help to frame the nature of evolution and its relationship to other concepts in science. The site provides an overview of the way that evolution has been tested. This information can be used to dispel the myths that have been created by creationists.
It is also possible to get the glossary of terms used in evolutionary biology. These terms include:
Adaptation is the process of changing heritable traits to be more suited to the environment. This is the result of natural selection, which happens when organisms with better adapted characteristics are more likely to survive and reproduce than those with less adapted traits.
Common ancestor (also called common ancestor) The most recent ancestor that is shared by two or more species. By studying the DNA of these species,
에볼루션 바카라 체험 it is possible to determine the common ancestor.
Deoxyribonucleic Acid: A massive biological molecular that holds 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 source of new genetic information within cells.
Coevolution is a relationship between two species, where the evolution of one species are influenced by evolutionary changes of the other. Examples of coevolution include the interactions between predator and prey or
무료에볼루션 host and parasite.
Origins
Species (groups which can interbreed) develop through a series of natural changes in the traits of their offspring. Changes can be caused by various factors, including natural selection, gene drift, and
에볼루션게이밍 mixing of the gene pool. The evolution of new species could take thousands of years. Environmental circumstances, such as climate changes or competition for food resources and habitat, can slow or accelerate the process.
The Evolution site traces the emergence of a variety of species of plants and animals over time and focuses on the most significant transitions that occurred in the history of each group. It also explores human evolution and is a subject that is of particular interest to students.
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 which is now believed to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was one year after the first edition of the Origin was published, it's highly unlikely that Darwin had seen or heard of it.
The site is primarily one of biology however,
에볼루션 바카라 it also has many details on geology and paleontology. One of the most appealing features on the site are a timeline of events that show how geological and climatic conditions have changed over time, as well as an outline of the distribution of some of the fossil groups featured on the site.
Although the site is a companion piece to the PBS television show however, it can stand on its own as a great source for teachers and students. The site is very well organized and provides clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms 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 on Earth has produced a diversity of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and
에볼루션게이밍 has many advantages over the modern observational and research methods of examining evolutionary processes. Paleobiology focuses on not only the process and events that take place regularly or over time, but also the relative abundance and
에볼루션 슬롯게임게이밍 (
click through the following website) distribution of different species of animals across the geological time.
The site is divided up into several routes that can be taken to learn about evolution. One of the paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The course also focuses on the most common misconceptions about evolution, as well as the history of evolutionary thought.
Each of the other sections of the Evolution site is similarly created, with resources that can be used to support a range of educational levels and pedagogical styles. The site includes a variety of interactive and multimedia resources, including animations, video clips and
에볼루션 virtual labs in addition to general textual content. The content is organized in a nested, bread crumb style that facilitates navigation and orientation on the web site.
The page "Coral Reef Connections" For instance, it provides a comprehensive overview of the coral's relationships and interactions with other organisms, and then is enlarged to show one clam that can communicate with its neighbours 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, provides an excellent introduction to many topics in evolutionary biology. The content also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis, which is a crucial tool for understanding the evolution of changes.
Evolutionary Theory
For biology students evolution is a crucial thread that connects all branches of the field. A wide selection of resources helps teachers teach evolution across all disciplines of life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides depth and breadth in its educational resources. The site features a wealth of interactive learning modules. It also features a "bread crumb structure" that assists students in moving away from the cartoon style that is used in Understanding Evolution and onto elements on this site that are more closely linked to the fields of research science. An animation that introduces the concept of genetics is linked to a page highlighting John Endler's experiments with artificial selection using guppies on native ponds in Trinidad.
