The Good And Bad About Evolution Site
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution remain. 바카라 에볼루션 has led many people to believe that biologists don't believe evolution.
This rich Web site - companion to the PBS series offers teachers with resources that promote evolution education and avoids the kinds of misinformation that can make it difficult to understand. It's laid out in a nested "bread crumb" format for ease of navigation and orientation.
Definitions
Evolution is a complicated and difficult subject to teach well. People who are not scientists often have a difficult time understanding the subject, and some scientists even use a definition which confuses it. This is particularly relevant when discussing the nature of the words themselves.
It is therefore important to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The website is a companion to the series that first aired in 2001, but is also an independent resource. The information is organized in a manner that makes it simpler to navigate and comprehend.
The site defines terms such as common ancestor and the gradual process. These terms help frame the nature of evolution as well as its relationship to other scientific concepts. The site gives a comprehensive overview of the way in which evolution has been examined. This information can be used to dispel myths that have been created by the creationists.
It is also possible to get the glossary of terms used in evolutionary biology. These terms include:
Adaptation is the process of changing heritable traits to be more suited to the environment. This is the result of natural selection. Organisms with more adaptable characteristics are more likely than those with less-adapted traits to survive and reproduce.
Common ancestor (also called common ancestor) The most recent ancestor shared by two or more species. By analyzing the DNA from these species it is possible to determine the common ancestor.
Deoxyribonucleic acid: A large biological molecule that contains information needed for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the basis for new genetic information within cells.
Coevolution is a relation between two species where evolution of one species influence evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or parasite and host.
Origins
Species (groups of individuals who can interbreed) change through a series of natural changes in the traits of their offspring. Changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The development of a new species can take thousands of years, and the process may be slowed down or accelerated by environmental conditions such as climate change or competition for food or habitat.
The Evolution site traces through time the emergence of various species of plants and animals, focusing on major transitions in each group's history. It also focuses on human evolution and is a subject that is particularly important for students.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was one year before the first edition of the Origin appeared, it is very unlikely that Darwin had seen or heard of it.
The site is mostly a biology site however, it also has lots of information about paleontology and geology. Among 에볼루션 바카라 of the website are a timeline of events that show the way in which climatic and geological conditions have changed over time, and a map of the distribution of some of the fossil groups featured on the site.
The site is a companion for the PBS TV series but it can also be used as a resource for teachers and students. The site is very well organized and provides clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These hyperlinks make it easier to move from the cartoon style of 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 produced a diversity of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment, has many advantages over modern observational or research methods for exploring evolutionary processes. In addition to exploring processes and events that take place frequently or over a long period of time, paleobiology allows to examine the relative abundance of different kinds of organisms as well as their distribution across the geological time.
The Web site is divided into various ways to learn about evolution, including "Evolution 101," which takes the user on a linear path through the nature of science and the evidence supporting the theory of evolution. The path also examines myths about evolution, and the background of evolutionary thinking.
Each of the main sections of the Evolution website is equally well-developed, with materials that can be used to support a variety of educational levels and teaching styles. In addition to general textual content, the site offers an array of interactive and multimedia resources, such as video clips, animations, and virtual labs. The breadcrumb-like arrangement of the content helps with navigation and orientation on the vast website.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of the coral's relationships and interactions with other organisms, and then is enlarged to show a single clam, which can communicate with its neighbors and respond to changes in conditions of the water that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages offers a great introduction to a variety of topics in evolutionary biology. The information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is a key tool in understanding evolutionary changes.
Evolutionary Theory
Evolution is a common thread that runs through all branches of biology. A wide range of resources helps teachers teach about evolution across all life sciences.
One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both depth and breadth in its educational resources. The site offers a variety of interactive learning modules. It also has a nested "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the field of research science. Animation that introduces the concept of genetics is linked to a page highlighting John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.
Another resource that is worth mentioning is the Evolution Library on this Web site, which has an extensive collection of multimedia items that are related to evolution. The content is organized into courses that are based on curriculum and follow the learning goals established in the standards for biology. It contains seven short videos designed for use in classrooms. They can be viewed online or purchased as DVDs.
A variety of crucial questions remain at the core of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is particularly true for the evolution of humans which was a challenge to reconcile religious beliefs that humanity has a unique place in creation and a soul, with the idea that innate physical traits evolved from the apes.
There are also a number of other ways in which evolution could occur and natural selection being the most well-known theory. Scientists also study other kinds like mutation, genetic drift, and sexual selection.
Many fields of inquiry have a conflict with literal interpretations of religious texts evolutionary biology has been the subject of fierce debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution but others haven't.
