7 Things You ve Never Learned About Evolution Site
Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, misconceptions persist regarding evolution. Pop science nonsense has led people to think that biologists don't believe in evolution.
This site, 에볼루션 바카라사이트 which is a complement to the PBS program offers teachers resources that promote evolution education, while avoiding the kinds of misconceptions that make it difficult to understand. It's laid out in the "bread crumb" format to make navigation and 에볼루션 슬롯 orientation easier.
Definitions
Evolution is a complex and difficult subject matter to teach effectively. It is often misunderstood by non-scientists, and even some scientists are guilty of using definitions that confuse the issue. This is especially relevant when it comes to the meaning of the words themselves.
It is therefore crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful way. The site is both an accompaniment to the 2001 series, and also a resource of its own. The content is presented in a nested fashion which aids navigation and orientation.
The site defines terms like common ancestor and the gradual process. These terms help define the nature and relationship of evolution to other scientific concepts. The site provides an overview of the manner in which evolution has been tested. This information can be used to dispel misconceptions that have been engendered by creationists.
You can also consult 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 due to natural selection. It occurs when organisms that have better-adapted traits are more likely survive and reproduce than those with less adapted traits.
Common ancestor (also known as common ancestor) The most recent ancestor that is shared by two or more species. The common ancestor can be identified by studying the DNA of those species.
Deoxyribonucleic acid: A large biological molecule that holds the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the source of new genetic information in cells.
Coevolution is a relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be observed in the interaction of predator and prey, or 에볼루션 사이트 - Planforexams.com - parasites and hosts.
Origins
Species (groups that can crossbreed) change through a series natural changes in their offspring's traits. These changes are caused by a variety such as natural selection, genetic drift and gene pool mixing. The evolution of new species can take thousands of years. Environmental conditions, like climate change or competition for food and habitat can slow or speed up the process.
The Evolution site traces the emergence of various species of plants and animals over time, focusing on the major shifts that occurred throughout the evolution of each group's history. It also focuses on the evolutionary origin of humans which is particularly important for students to comprehend.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The famous skullcap, with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, one year before the first edition of the Origin appeared, it is highly unlikely that Darwin had heard or seen of it.
While the site focuses on biology, it contains a wealth of information about geology as well as paleontology. The website has numerous features that are particularly impressive, such as a timeline of the way that climate and geological conditions have changed over time. It also includes maps that show the locations of fossil groups.
The site is a companion for the PBS TV series but it could also be used as a resource for teachers and students. The site is very well-organized and offers clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. In particular there are hyperlinks to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has produced a variety of animals, plants and insects. Paleobiology is the study of these creatures within their geological context and has numerous advantages over the modern observational and research methods for analyzing evolutionary phenomena. Paleobiology is able to study not only processes and events that occur regularly or over time, but also the relative abundance and distribution of different species of animals in space throughout geological time.
The website is divided into several optional pathways to understanding evolution that include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence that supports the theory of evolution. The path also examines myths about evolution and the background of evolutionary thinking.
Each of the other major sections of the Evolution site is equally well constructed, with materials that can be used to support a range of educational levels and pedagogical styles. The site has a range of interactive and multimedia resources that include videos, animations, and virtual laboratories as well as general textual content. The breadcrumb-like arrangement of the content aids in navigation and orientation on the vast web site.
The page "Coral Reef Connections" For instance, 에볼루션사이트 it provides a comprehensive overview of coral relationships and interactions with other organisms, and then zooms in to one clam that is able communicate with its neighbors and react to changes in the conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to a broad range of topics in evolutionary biology. The material includes an explanation of the importance of natural selection and the concept of phylogenetics as a key tool for understanding evolutionary changes.
Evolutionary Theory
For biology students the concept of evolution is a major thread that connects all the branches of the field. A wide selection of resources helps teachers teach evolution across the disciplines of life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that offers both depth and breadth in its educational resources. The site has a variety of interactive learning modules. It also features an encased "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this large Web site closer to the world of research science. For instance an animation that introduces the concept of genetic inheritance links to a page that focuses on John Endler's artificial selection experiments with guppies in native ponds of Trinidad.
The Evolution Library on this website contains a large multimedia library of materials that deal with evolution. The content is organized according to curriculum-based paths that parallel the learning goals established in the biology standards. It includes seven short videos designed specifically for use in classrooms, and can be streamed for 에볼루션 무료체험 no cost or purchased on DVD.
Many important questions remain in the midst of evolutionary biology, such as what triggers evolution and how fast it occurs. This is especially relevant to human evolution, which has made it difficult to reconcile that the physical characteristics of humans evolved from apes and religious beliefs that claim that humanity is unique among living things and holds a a special place in creation, with soul.
In addition there are a myriad of ways that evolution can be triggered, with natural selection being the most widely accepted theory. Scientists also study different types such as mutation, genetic drift, and sexual selection.
Many fields of inquiry are in conflict with the literal interpretations of religious texts, evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, others have not.
