Evolution Site Tips That Will Change Your Life
Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, misconceptions persist about evolution. Pop science nonsense has led many people to believe that biologists aren't believers in evolution.
This rich Web site - companion to the PBS series offers teachers with resources that support evolution education and help avoid the kinds of misinformation that can hinder it. It's laid out in a "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach effectively. It is often misunderstood even by non-scientists, and even some scientists are guilty of using a definition that confuses the issue. This is particularly relevant when discussing the nature of the words themselves.
It is crucial 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 manner. The site is a companion to the show that premiered in 2001, but is also an independent resource. The material is presented in a way that assists in navigation and orientation.
The site defines terms such as common ancestor and gradual process. These terms help frame the nature and significance of evolution with other scientific concepts. The site gives a comprehensive overview of the ways in which evolution has been examined. This information can help dispel myths that are created by the creationists.
You can also access a glossary which includes terms that are used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to become more suited to the environment. This is the result of natural selection, which occurs when organisms that are more adaptable characteristics are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor: The most recent common ancestor of two or more species. By studying the DNA of these species, it is possible to identify the common ancestor.
Deoxyribonucleic Acid: A massive biological molecular containing the necessary information for cell replication. The information is stored in a sequence of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the cause of new genetic information within cells.
Coevolution: A relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey or the parasite and the host.
Origins
Species (groups that can interbreed), evolve through a series natural changes in their offspring's traits. The changes can be triggered by a variety of causes that include natural selection, genetic drift and mixing of gene pools. The development of new species can take thousands of years. Environmental conditions, such as climate change or competition for food and habitat can slow or speed up the process.
The Evolution site tracks through time the evolution of various animal and plant groups, focusing on major transitions in each group's past. It also explores the human evolutionary roots and humans, a subject that is particularly important for students to understand.
Darwin's Origin was published in 1859, when just a few antediluvian fossils of human beings had been discovered. The famous skullcap, 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 highly unlikely that Darwin knew about the skullcap, which was first published in 1858, a year following the initial edition of The Origin.
While the site focuses on biology, it contains a wealth of information on geology and paleontology. The website has several aspects that are quite impressive, such as an overview of how climate and 에볼루션 슬롯게임 블랙잭 (Git.Fuwafuwa.Moe) geological conditions have changed over time. It also includes an interactive map that shows the location of fossil groups.
The site is a companion to the PBS television series, but it could also be used as a source for teachers and students. The site is well-organized and offers clear links to the introductory content of Understanding Evolution (developed under the National Science Foundation's assistance) as well as the more specialized features of the museum's website. These links facilitate the transition 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. They illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has led to many species of plants, animals and insects. Paleobiology is the study of these creatures in their geographical context and offers a number of advantages over the modern observational and research methods of examining evolutionary phenomena. In addition to examining processes and events that take place frequently or over a long period of time, paleobiology allows to analyze the diversity of species of organisms and their distribution across geological time.
The Web site is divided into various ways to learn about evolution that include "Evolution 101," which takes the user on a linear path through the scientific process and the evidence supporting the theory of evolution. The path also reveals common misconceptions about evolution and the evolution of thought.
Each of the main sections of the Evolution website is equally well-designed, with materials that are suited to a variety of educational levels and teaching styles. The site has a range of interactive and 무료 에볼루션 multimedia resources, including animations, video clips and virtual labs in addition to general textual content. The breadcrumb-like organization of the content helps with navigation and orientation on the vast Web site.
The page "Coral Reef Connections" For instance, it gives a brief overview of coral relationships and their interactions with other organisms and then zooms in to one clam, which can communicate with its neighbors and respond to changes in conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to the many areas of evolutionary biology. The content also includes a discussion on the importance of natural selection and the concept phylogenetics analysis as a key method for understanding the evolution of change.
Evolutionary Theory
For biology students, evolution is a key thread that weaves together all the branches of the field. A vast collection of resources can help teachers teach about evolution across all life sciences.
One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page 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 allows students to move from the cartoon-like style of Understanding Evolution to elements on this massive website that are more closely tied to the field of research science. Animation that introduces the concept of genetics, which links to a page highlighting John Endler's experiments with artificial selection using guppies on native ponds in Trinidad.
The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized into courses that are based on curriculum and follow the learning objectives outlined in biology standards. It contains seven videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.
Evolutionary biology is a field of study that has many important questions to answer, such as what triggers evolution and how fast it happens. This is particularly true for humans' evolution, where it was difficult to reconcile religious beliefs that humans have a distinct position in the universe and a soul with the notion that our physical traits evolved from apes.
Additionally there are a variety of ways that evolution can be triggered and 에볼루션 바카라 (xintangtc.com) natural selection is the most widely accepted theory. However scientists also study different kinds of evolution like genetic drift, mutation, and sexual selection, among other things.
While many scientific fields of study have a conflict with literal interpretations found in religious texts, the concept of evolution biology has been a subject of intense debate and opposition from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, but others haven't.
