5 Evolution Site Lessons From The Pros
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution persist. Pop science nonsense has led many people to believe that biologists don't believe evolution.
This site, a companion to the PBS program, provides teachers with materials that support the evolution of education while avoiding the types of misconceptions which make it difficult to understand. It's organized in a "bread crumb" format to aid in navigation and orientation.
Definitions
Evolution is a complex and difficult subject to teach effectively. It is often misunderstood by non-scientists, and even scientists have been guilty of using a definition that confuses the issue. This is especially relevant when discussing the nature of the words themselves.
It is therefore important to define the terms used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful way. The site is a companion site to the show which first aired in 2001, but also functions as an independent resource. The information is presented in an organized manner that makes it simpler to navigate and comprehend.
The site defines terms such as common ancestor, gradual process, and adaptation. These terms help to frame the nature of evolution and its relation to other concepts in science. The site provides an overview of the ways that evolution has been tested. This information can help dispel myths created by creationists.
You can also access a glossary that contains terms that are used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable traits to become better suitable to a particular setting. This is the result of natural selection. Organisms with better-adapted traits are more likely than those with less adapted traits to survive and reproduce.
Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified by studying the DNA of the species.
Deoxyribonucleic Acid: A large biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.
Coevolution is a relation between two species, where the evolutionary changes of one species influence evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey or the parasite and the host.
Origins
Species (groups that can crossbreed) change by a series of natural variations in their offspring's traits. The changes can be caused by a variety such as natural selection, genetic drift and mixing of gene pools. The evolution of new species can take thousands of years. Environmental circumstances, such as changes in the climate or 에볼루션바카라사이트 competition for food resources and habitat can slow or speed up the process.
The Evolution site tracks the development of a number of different animal and plant groups through time and focuses on the most significant transitions that occurred in the history of each group. It also focuses on human evolution as a subject that is particularly important to students.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The famous skullcap, with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap when it was published in 1858, one year after the first edition of The Origin.
The site is mostly an online biology resource however it also includes a lot of information on paleontology and geology. Among the best features of the Web site are a series of timelines that illustrate how geological and climatic conditions changed over time, as well as a map of the distribution of some fossil groups that are featured on the site.
The site is a companion for a PBS TV series but it can be used as a source for teachers and students. The site is extremely well-organized and has clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with guppies. They demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has resulted in a variety of animals, plants, and insects. Paleobiology, the study of these creatures within their geological environment offers many advantages over modern observational or experimental methods for exploring evolutionary phenomena. Paleobiology focuses on not only processes and events that take place regularly or over time, but also the relative abundance and distribution of different species of animals across the geological time.
The website is divided into various paths that can be chosen to gain knowledge about evolution. One of the paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The path also explores misconceptions regarding evolution, as well as the history of evolutionary thought.
Each of the main sections of the Evolution website is equally well-developed, and includes materials that can be used to support a variety of educational levels and teaching styles. The site includes a variety of interactive and multimedia resources which include video clips, animations and virtual labs, in addition to its 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.
The page "Coral Reef Connections" For instance, it provides an overview of the coral's relationships and interactions with other organisms and then zooms in on one clam, which is able to communicate with its neighbors and respond to changes in water conditions that occur on 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 explanation of the importance of natural selection and the concept of phylogenetics, an important tool for understanding evolutionary changes.
Evolutionary Theory
For biology students, evolution is a key thread that weaves together all branches of the field. A vast collection of books helps in teaching evolution across the life science disciplines.
One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and breadth in its educational resources. The site has a variety of interactive learning modules. It also has an "bread crumb structure" that allows students to move away from the cartoon-like style that is used in Understanding Evolution and onto elements on this site that are more closely linked to the realms of research science. An animation that introduces students to the concept of genetics, which links to a page about John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad.
The Evolution Library on this website is a vast multimedia library of assets related with evolution. The content is organized in curriculum-based pathways that correspond to the learning goals set forth in the standards for biology. It includes seven short videos intended for 에볼루션 use in the classroom. These are available to stream or purchase as DVDs.
Evolutionary biology is still a field of study that has many important questions, including what causes evolution and the speed at which it happens. This is particularly relevant to human evolution, which has made it difficult to reconcile that the physical characteristics of humans derived from apes, and 에볼루션 사이트 (just click the up coming website) the religious beliefs that hold that humanity is unique among living things and has a special place in creation. It is soul.
There are a variety of other ways in which evolution can take place and natural selection being the most widely accepted theory. However, scientists also study other types of evolution such as genetic drift, mutation, and sexual selection, among other things.
While many fields of scientific inquiry are in conflict with the 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, others aren't.
