15 Evolution Site Benefits You Should All Know
Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, misinformation about evolution persist. People who have been exposed to popular science myths often assume that biologists don't believe in evolution.
This rich Web site - companion to the PBS series It provides teachers with materials which support evolution education and help avoid the kinds of misconceptions that make it difficult to understand. It's organized in the "bread crumb" format to make navigation and orientation easier.
Definitions
It is difficult to teach evolution 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 to discussions about the meaning 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 helpful manner. The site is a companion site to the show which first aired in 2001, but it can also function as an independent resource. The content is presented in a structured way that makes it easy to navigate and comprehend.
The site defines terms like common ancestor, gradual process and so on. These terms help define the nature and significance of evolution to other scientific concepts. The site provides an overview of the ways that evolution has been examined. This information can be used to dispel misconceptions that have been propagated by the creationists.
You can also access a glossary that contains terms used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable characteristics to become more suited to a particular environment. This is the result of natural selection, which occurs when organisms with more adaptable traits are more likely survive and reproduce than those with less adaptable traits.
Common ancestor: The most recent common ancestor of two or more different species. The common ancestor can be identified by studying the DNA of these species.
Deoxyribonucleic Acid: A huge biological molecular that holds the necessary information for cell replication. The information is contained in a sequence of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
무료 에볼루션 is a relation between two species, where the evolution of one species are influenced evolutionary changes of the other. Coevolution is evident through the interaction between predator and prey, or parasite and hosts.
Origins
Species (groups that can crossbreed) change by a series of natural variations in the traits of their offspring. These changes can be caused by various factors, including natural selection, gene drift, and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, like changes in the climate or competition for food and habitat can slow or speed up the process.
The Evolution site tracks the evolution of various groups of animals and plants over time with a focus on the key changes that took place in the evolution of each group's history. It also focuses on the evolutionary origin of humans, a topic that is particularly important for students to understand.
When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. One of them was the infamous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is highly unlikely that Darwin was aware of the skullcap when it was published in 1858, a year after the first edition of The Origin. Origin.
While the site focuses on biology, it also contains a wealth of information on geology and paleontology. The site offers a number of features that are particularly impressive, including the timeline of the way that climate and geological conditions have changed over the course of time. It also has an interactive map that shows the location of fossil groups.
The site is a companion to a PBS TV series but it can also be used as an educational resource by teachers and students. 에볼루션 무료 바카라 is well-organized and offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's 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 that illustrate the importance ecology in evolutionary theory.
Diversity
The evolution of life 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 in its exploration of evolutionary phenomena. Paleobiology is able to study not only the process and events that take place regularly or over time, but also the relative abundance and distribution of various animal groups in space over the course of the geological time.
The Web site is divided into various pathways to understanding evolution which include "Evolution 101," which takes the viewer on a line through the science of nature and the evidence that supports the theory of evolution. The course also focuses on common misconceptions about evolution as well as the evolution of thought.
Each of the main sections of the Evolution website is equally well-designed, with materials that can be used to support a variety of educational levels and teaching styles. In addition to general textual content, the site also has an array of interactive and multimedia resources, such as videos, animations, and virtual laboratories. The breadcrumb-like organization of the content aids in navigation and orientation on the vast web site.
에볼루션 슬롯게임 For instance, it provides a comprehensive overview of the relationships between corals and interactions with other organisms and is enlarged to show one clam, which is able communicate with its neighbors and respond to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The information also includes a discussion of the role of natural selection and the concept of phylogenetic analysis which is a key tool for understanding the evolution of change.
Evolutionary Theory
Evolution is an underlying thread that runs through all branches of biology. A wide range of resources can help teachers teach about evolution across the life sciences.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth as well as wide range of educational resources. The site has a wide array of interactive learning modules. It also features an embedded "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the world of research science. For instance an animation that explains the concept of genetic inheritance links to a page that highlights John Endler's artificial selection experiments with guppies in native ponds of Trinidad.
Another useful resource is the Evolution Library on this website, which includes an extensive multimedia library of resources connected to evolution. The content is organized into curriculum-based pathways that correspond to the learning goals set forth in the biology standards. It contains seven videos specifically designed for classroom use, which can be streamed for no cost or purchased on DVD.
A number of important questions remain at the heart of evolutionary biology, including the factors that trigger evolution and the speed at which it occurs. This is particularly true for the evolution of humans which was a challenge to reconcile religious beliefs that humanity has a special place in creation and a soul, with the notion that our physical traits originated from Apes.
There are a myriad of other ways in which evolution can take place including natural selection, which is the most well-known theory. Scientists also study other types such as genetic drift, and sexual selection.
While many fields of scientific study have a conflict with literal interpretations found in religious texts, the concept of evolution biology has been a source of intense debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, other religions aren't.
