What Evolution Site Experts Want You To Be Educated
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution remain. People who have taken in popular science myths often assume that biologists claim they do not believe in evolution.
This rich Web site - companion to the PBS series - provides teachers with materials that promote evolution education and help avoid the kinds of misconceptions that undermine it. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach well. It is often misunderstood by non-scientists and even some scientists have been guilty of using definitions that confuse the issue. This is especially true when discussing the meaning of the words themselves.
It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. It is an accompanying site for the 2001 series, and also a resource of its own. The material is presented in an organized manner that makes it simpler to navigate and comprehend.
The site defines terms like common ancestor (or common ancestor), gradual process and adaptation. These terms help to define the nature and significance of evolution with other scientific concepts. The site provides an overview of the ways in which evolution has been tested. This information can be used to dispel myths that have been created by the creationists.
You can also consult a glossary that includes terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to be better suited to an environment. This is the result of natural selection, which happens when organisms that are more adaptable traits are more likely to survive and reproduce than those with less adaptable traits.
Common ancestor (also known as common ancestor) The most recent ancestral ancestor shared by two or more species. By analyzing the DNA from these species it is possible to identify the common ancestor.
Deoxyribonucleic acid: A massive biological molecule that contains the information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together to form long chains, also known as chromosomes. Mutations are the basis for new genetic information within cells.
Coevolution is a relation between two species in which the evolution of one species are influenced by evolutionary changes of the other. Coevolution can be observed in the interaction of predator and prey, or parasite and hosts.
Origins
Species (groups that can interbreed) change through a series of natural changes in their offspring's traits. The causes of these changes are various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of a new species can take thousands of years, and the process can be slowed down or speeded up by environmental factors like climate change or the competition for food or habitat.
The Evolution site tracks through time the emergence of various groups of animals and plants, focusing on major transitions in each group's past. It also explores the human evolutionary roots and humans, a subject that is crucial for students to understand.
Darwin's Origin was published in 1859, at a time when only a handful of antediluvian fossils of human beings had been discovered. The skullcap that is famous, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was one year after the first edition of the Origin appeared, it is extremely unlikely that Darwin had heard or seen of it.
The site is mostly an online biology resource however, it also has many details on geology and paleontology. One of the most appealing features on the site are a series of timelines which show the way in which climatic and geological conditions have changed over time as well as a map of the geographical distribution of some fossil groups that are featured on the site.
The site is a companion to a PBS TV series but it can also be used as an educational resource for teachers and students. The site is very well-organized and offers clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks make it easy to transition from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are also 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 produced a diversity of animals, plants, and insects. Paleobiology, the study of these creatures within their natural environment offers many advantages over modern observational or research methods for exploring evolutionary phenomena. In addition to exploring the processes and events that happen regularly or over a lengthy period of time, paleobiology allows to analyze the diversity of groups of organisms and their distribution in space over geological time.
The site is divided up into several options to gain knowledge about evolution. One of the paths, "Evolution 101," takes the viewer through the nature and evidence of evolution. The path also examines myths about evolution as well as the history of evolutionary thinking.
Each of the other main sections of the Evolution site is similarly developed, with materials that can be used to support a range of curriculum levels and pedagogical styles. In addition to the general textual content, the site features a wide range of multimedia and interactive content like videos, animations and virtual labs. The breadcrumb-like arrangement of the content helps with navigation and orientation on the vast Web site.
For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interaction with other organisms, then zooms in on a single clam that can communicate with its neighbors and respond to changes in the water conditions that occur at the level of the reef. This page, along with the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to a broad spectrum of topics in evolutionary biology. The content includes an explanation of the importance of natural selection and the concept of phylogenetics which is a crucial method for understanding the evolution of changes.
Evolutionary Theory
For biology students, evolution is a key thread that weaves together all the branches of the field. A vast collection of books helps in teaching evolution across all life science disciplines.
One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides depth and a variety of educational resources. The site has a wide array of interactive learning modules. It also features a "bread crumb structure" that allows students to move away from the cartoon-like style of Understanding Evolution and onto elements on this large website more closely related to the worlds of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page highlighting John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad.
The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives outlined in the biology standards. It contains seven videos that are designed for classroom use. These can be viewed online or purchased as DVDs.
에볼루션 바카라사이트 of important questions remain in the midst of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is particularly true for humans' evolution which was a challenge to reconcile religious beliefs that held that humanity has a unique place in the creation and a soul, with the notion that our physical traits evolved from apes.
In addition, there are a number of ways that evolution can occur and natural selection is the most popular theory. 에볼루션 카지노 사이트 study other kinds such as mutation, genetic drift, and sexual selection.
While many scientific fields of inquiry conflict with the literal interpretations of religious texts, evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, but others haven't.
