Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, there are still misconceptions about the evolution. People who have been exposed to popular science myths often assume that biologists are saying they don't believe in evolution.
This site, which is a companion to the PBS series offers teachers with resources that support evolution education and avoid the kinds of myths that undermine it. It's organized in a "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complex and challenging subject to teach effectively. 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 it comes to discussions about the meaning of the word itself.
It is therefore essential to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site is both a companion for the 2001 series, but also a resource on its own. The material is organized in a manner that makes it easier to navigate and comprehend.
The site defines terms such as common ancestor, gradual process and so on. These terms help to frame the nature of evolution as well as its relation to other concepts in science. The site also provides an overview of how the concept of evolution has been researched and verified. This information can be used to dispel the myths that have been engendered by creationists.
You can also access a glossary which contains terms that are used in evolutionary biology. These terms include:
Adaptation is the process of changing hereditary traits to become more suitable to their environment. This is a result of natural selection, which happens when organisms that are better-adapted traits are more likely to survive and reproduce than those with less adaptable traits.
Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified through analyzing the DNA of those species.
Deoxyribonucleic Acid: A large biological molecular that contains the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains called chromosomes. Mutations are the cause of new genetic information within cells.
Coevolution is the relationship between two species, where the evolution of one species influence evolutionary changes in the other. Coevolution can be observed in the interaction of predator and prey, or parasites and hosts.
Origins
Species (groups that can interbreed) change by a series of natural variations in the traits of their offspring. These changes are caused by a variety of causes, including natural selection, genetic drift and mixing of genes. The development of a new species may take thousands of years and the process can be slowed down or speeded up due to environmental conditions, such as climate change or the competition for food or habitat.
The Evolution site tracks through time the emergence of various animal and plant groups and focuses on major changes in each group's past. It also focuses on the human evolutionary roots which is especially important for students to understand.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The famous skullcap, along with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap when it was published in 1858, which was a year after the publication of the first edition of The Origin. Origin.
While the site is focused on biology, it contains a wealth of information about geology and paleontology. Among the best features of the Web site are a timeline of events which show how climatic and geological conditions changed over time, as well as an interactive map of the distribution of a few fossil groups that are featured on the site.
The site is a companion to a PBS television series, but it can also be used as a source for teachers and students. The site is well-organized and 에볼루션 바카라 체험 provides clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features of the museum website. These links 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, which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a variety of plants, animals, and insects. Paleobiology is the study of these creatures in their natural environment and has a number of advantages over modern observational and experimental methods of examining evolutionary processes. In addition to exploring processes and events that take place frequently or over a long period of time, paleobiology can be used to analyze the diversity of kinds of organisms as well as their distribution throughout the course of geological time.
The website is divided into several optional paths to learning evolution which include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence that supports the theory of evolution. The course also focuses on common misconceptions about evolution and the evolution theory's history.
Each of the other sections of the Evolution site is equally constructed, with materials that can be used to support a range of curriculum levels and 에볼루션사이트 pedagogical styles. The site has a range of multimedia and interactive resources which include animations, video clips and virtual labs, in addition to its general textual content. The content is organized in a nested, 무료에볼루션 bread crumb style that facilitates navigation and orientation within the vast web site.
For example the page "Coral Reef Connections" provides an overview of the relationships between corals and their interaction with other organisms. Then, it concentrates on a specific clam that is able to communicate with its neighbors and react to changes in the water conditions that take place at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages provides an excellent introduction to many topics in evolutionary biology. The content also includes an overview of the importance of natural selection and the concept of phylogenetic analysis which is a crucial method to understand evolutionary changes.
Evolutionary Theory
For 에볼루션코리아 biology students, evolution is a key thread that weaves together 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 site that provides the depth and the wide range of educational resources. The site has a wide array of interactive learning modules. It also features 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 connected to the worlds of research science. An animation that introduces students to the concept of genetics is linked to a page that highlights John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.
Another helpful resource is the Evolution Library on this site, which has an extensive library of multimedia resources that are related to evolution. The content is organized in curricula-based paths that correspond to the learning objectives set out in the standards for biology. It contains seven videos specifically intended for use in the classroom. These can be viewed online or purchased as DVDs.
Evolutionary biology remains an area of study that poses many important questions, such as what triggers evolution and how fast it occurs. This is particularly true for the evolution of humans which was a challenge to reconcile religious beliefs that held that humans have a distinct position in the universe and a soul with the notion that human beings have innate physical traits originated from Apes.
In addition, there are a number of ways in which evolution could occur, with natural selection being the most popular theory. However, scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among other things.
While many fields of scientific study have a conflict with the literal interpretations of religious texts, evolution biology has been a source of intense debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolution, but others haven't.
