15 Amazing Facts About Evolution Site You ve Never Heard Of
Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, there are still misconceptions regarding evolution. People who have absorbed popular science myths often assume that biologists are saying they do not believe in evolution.
This rich website - companion to the PBS series - provides teachers with materials that support evolution education and avoid the kinds of misconceptions that hinder it. It's organized in a "bread crumb" format to facilitate navigation and orientation.
Definitions
It's difficult to properly teach evolution. It is often misunderstood by non-scientists, and 바카라 에볼루션코리아 - these details, even scientists have been guilty of using a definition that confuses the issue. This is particularly applicable to debates about the meaning of the word itself.
It is therefore crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful manner. The site is a companion site to the show which first aired in 2001, but it also functions as an independent resource. The information is organized in a way that makes it easy to navigate and comprehend.
The site defines terms like common ancestor and 에볼루션게이밍 gradual process. These terms help define the nature and significance of evolution with other scientific concepts. The site gives a comprehensive overview of the way the concept of evolution has been examined. This information can be used to dispel myths that have been engendered by creationists.
It is also possible to find the glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable traits to become better suited to a particular environment. This is the result of natural selection. Organisms with better-adapted characteristics are more likely than those with less adaptable traits to reproduce and survive.
Common ancestor: The most recent common ancestor of two or more species. By analyzing DNA from these species it is possible to determine the common ancestor.
Deoxyribonucleic Acid: A massive biological molecular that holds the information required for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, called chromosomes. Mutations are responsible for the creation of new genetic information within cells.
Coevolution is a relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution include the interaction between predator 에볼루션카지노사이트 (http://appc.cctvdgrw.com/home.php?mod=space&uid=1966208) and prey, or parasite and host.
Origins
Species (groups of individuals that can interbreed) develop through an array of natural changes in the characteristics of their offspring. The causes of these changes are various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental circumstances, such as climate change or competition for food or habitat, can slow or accelerate the process.
The Evolution site tracks through time the evolution of various groups of animals and plants with a focus on major changes in each group's history. It also examines the evolutionary history of humans, a topic that is crucial for students to comprehend.
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 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year after the first edition of the Origin was published, it's extremely unlikely that Darwin had seen or heard of it.
The site is primarily one of biology however it also includes many details on geology and paleontology. The site offers several features that are especially impressive, including an overview of how geological and climate conditions have changed over the course of time. It also includes a map showing the distribution of fossil groups.
Although the site is a companion to the PBS television show, it also stands on its own as a great source for teachers and students. The site is well-organized and offers clear links to the introductory material of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized features of the museum website. These links facilitate the transition from the enthralling 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 illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology is the study of these creatures within their geographical context and offers a number of advantages over the modern observational and research methods of examining evolutionary processes. Paleobiology is able to study not only the process and events that occur frequently or over time, but also the distribution and frequency of various animal groups in space throughout the geological time.
The Web site is divided into various pathways to understanding evolution that include "Evolution 101," which takes the user on a linear path through the scientific process and the evidence that supports the theory of evolution. The path also explores common misconceptions about evolution and the evolution of thought.
Each of the main sections on the Evolution website is equally well-designed, with materials that can be used to support a variety of curriculum levels and teaching styles. The site offers a wide array of multimedia and interactive resources that include video clips, animations and virtual laboratories, in addition to its general textual content. The content is organized in a nested, bread crumb fashion that aids navigation and orientation on the web site.
For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms. Then, it concentrates on a specific clam that can communicate with its neighbors and respond to changes in the water conditions that take place at the level of the reef. This page, 에볼루션 바카라 along with the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a broad range of topics in evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a crucial method to understand evolutionary changes.
Evolutionary Theory
Evolution is a common thread that is found throughout 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 television series Understanding Evolution is an excellent example of a Web site that provides depth as well as breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also has an "bread crumb structure" that assists students in moving away from the cartoon style used in Understanding Evolution and onto elements of this vast website that are closely connected to the realms of research science. For example an animation that explains the idea of genetic inheritance connects to a page that focuses on John Endler's experiments in artificial selection with guppies in native ponds of Trinidad.
Another useful resource is the Evolution Library on this site, which has an extensive library of multimedia assets that are related to evolution. The content is organized according to curricula-based pathways that correspond to the learning objectives outlined in the standards for biology. It contains seven videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD.
A variety of crucial questions remain in the midst of evolutionary biology, including what triggers evolution and 에볼루션바카라 the speed at which it occurs. This is particularly true for humans' evolution where it was a challenge to reconcile religious beliefs that humanity has a unique place in the creation and a soul with the notion that human beings have innate physical traits were derived from the apes.
There are a myriad of other ways in which evolution could occur including natural selection, which is the most popular theory. Scientists also study different types such as genetic drift, and sexual selection.
While many scientific fields of study have a conflict with literal interpretations found in religious texts, the concept of evolution biology has been the subject of intense debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, while others haven't.
