Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions persist about evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.
This site, a companion to the PBS program, provides teachers with materials which support evolution education, while avoiding the kinds of misconceptions that can hinder it. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
It's not easy to properly teach evolution. It is often misunderstood by non-scientists and even scientists use definitions that confuse the issue. This is particularly true when it comes to discussions on the nature of the word.
It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful manner. The site is a companion site to the series that first aired in 2001, but is also an independent resource. The information is presented in a structured way that makes it easy to navigate and understand.
The site defines terms such as common ancestor, gradual process and adaptation. These terms help to define the nature of evolution as well as its relationship to other concepts in science. The site provides an overview of the way in which evolution has been examined. This information can be used to dispel myths that have been engendered by the creationists.
You can also consult a glossary that includes terms that are used in evolutionary biology. These terms include:
Adaptation: The tendency of heritable characteristics to become more adaptable to a specific environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less adaptable traits to reproduce and survive.
Common ancestor (also called common ancestor) The most recent ancestral ancestor shared by two or more species. The common ancestor can be identified by analyzing the DNA of the species.
Deoxyribonucleic Acid: A massive biological molecular that contains the information needed 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 responsible for the creation of new genetic information within cells.
Coevolution is the relationship between two species in which the evolutionary changes of one species are influenced evolutionary changes in the other. Coevolution is evident in the interaction of predator and prey, or parasite and hosts.
Origins
Species (groups of individuals that can interbreed) develop through a series of natural changes in the characteristics of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food and habitat, can slow or accelerate the process.
에볼루션게이밍 through time the evolution of different groups of animals and plants with a focus on major changes within each group's past. It also explores the evolutionary history of humans, a topic that is crucial for students to understand.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The skullcap that is famous, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, one year after the publication of the first edition of The Origin. Origin.
The site is mostly an online biology resource however, it also has a lot of information on paleontology and geology. The Web site has numerous features that are especially impressive, such as an overview of how climate and geological conditions have changed over time. It also has a map showing the distribution of fossil groups.
While the site is a companion piece to a PBS television show however, it can stand on its own as a great resource for teachers and students. The site is well-organized, and provides easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's funding) and the more specialized features of the museum's website. These hyperlinks facilitate the move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also links to John Endler's experiments with guppies that illustrate 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 is the study of these creatures in their natural environment is a superior method of study over modern observational or experimental methods for studying evolutionary processes. Paleobiology focuses on not just the processes and events that occur regularly or over time, but also the relative abundance and distribution of various animal groups in space over the course of geological time.
The site is divided into several optional pathways to understanding evolution that include "Evolution 101," which takes the viewer on a line through the science of nature and the evidence supporting the theory of evolution. The path also explores the most common misconceptions about evolution, as well as the evolution theory's history.
Each of the main sections of the Evolution website is equally well-developed, and includes materials that support a variety curriculum levels and teaching styles. In addition to the general textual content, the site also has a wide range of interactive and multimedia resources, such as videos, animations, and virtual laboratories. The breadcrumb-like arrangement of the content helps with navigation and orientation on the massive website.
For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms. Then, it zooms in on a single clam that can 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 offers a great introduction to the many areas of evolutionary biology. The information also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis which is a key tool in understanding evolutionary changes.
에볼루션 블랙잭 is an underlying thread that connects all branches of biology. A vast collection of resources helps teachers teach about evolution across the life sciences.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that offers both the depth and the broadness in terms of educational resources. The site offers a variety of interactive learning modules. It also features an encased "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this huge site that are more closely linked to the world of research science. For instance, an animation introducing the idea of genetic inheritance connects to a page highlighting John Endler's experiments in artificial selection using guppies in the ponds of his native country of Trinidad.
The Evolution Library on this website has a huge multimedia library of resources that are associated to evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives outlined in the biology standards. It contains seven short videos that are designed for use in classrooms. These are available to stream or purchase as DVDs.
Many important questions remain in the midst of evolutionary biology, including what triggers evolution and how fast it happens. This is especially true in the case of human evolution which was a challenge to reconcile religious beliefs that humanity has a unique position in the universe and a soul with the notion that human beings have innate physical traits were derived from the apes.
Additionally, there are a number of ways that evolution could be triggered with natural selection being the most popular theory. Scientists also study other types such as mutation, genetic drift and sexual selection.
Many fields of inquiry conflict with literal interpretations of religious texts Evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions aren't.
