A Guide To Evolution Site From Beginning To End
Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, there are still a lot of misconceptions regarding evolution. People who have been exposed to popular science myths often assume that biologists claim they don't believe in evolution.
This rich Web site, which is a complement to the PBS program that provides teachers with resources which support evolution education while avoiding the types of misconceptions which make it difficult to understand. It's laid out in the "bread crumb" format to facilitate navigation and orientation.
Definitions
It is difficult to properly teach evolution. It is often misunderstood by non-scientists, and even scientists use definitions that confuse the issue. This is particularly relevant to discussions on the nature of the word.
As such, it is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient manner. It is a companion for the 2001 series, but also a resource on its own. The information is presented in an organized way that makes it easy to navigate and comprehend.
The site defines terms such as common ancestor, gradual process and so on. These terms help frame the nature and relationship of evolution to other concepts in science. The website then provides an overview of how the concept of evolution has been vetted and verified. This information can be used to dispel myths that have been engendered by the creationists.
It is also possible to find the glossary of terms used in evolutionary biology. These terms include:
Adaptation is the tendency of heritable traits to be more suited to the environment. This is the result of natural selection. Organisms with better-adapted characteristics are more likely than those with less-adapted traits to reproduce and survive.
Common ancestor: 에볼루션 무료체험 The most recent common ancestor of two or more distinct species. By studying the DNA of these species it is possible to identify the common ancestor.
Deoxyribonucleic Acid: A huge biological molecular containing the information required for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are the cause of new genetic information within cells.
Coevolution is a relationship between two species, where the evolution of one species are influenced evolutionary changes in the other. Coevolution can be observed in the interactions between predator and prey, or 에볼루션 코리아 parasites and hosts.
Origins
Species (groups of individuals who can interbreed) evolve through an array of natural changes in the characteristics of their offspring. These changes can be caused by numerous factors, like natural selection, gene drift and mixing of the gene pool. The development of a new species may take thousands of years and the process could be slowed or increased due to environmental conditions, such as climate change or 에볼루션 무료체험 슬롯게임 (https://telegra.Ph/) the competition for food or habitat.
The Evolution site traces the emergence of a variety of species of plants and animals over time and focuses on the most significant transitions that occurred in the evolution of each group's history. It also explores the human evolutionary roots, a topic that is crucial for students to know.
Darwin's Origin was written in 1859, when just a few antediluvian fossils of humans had been found. Among them was the famous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, just one year after the first edition of the Origin was published, it's highly unlikely that Darwin had ever heard of it.
The site is mostly an online biology resource however, it also has a lot of information on geology and paleontology. The most impressive features of the Web site are a set of timelines which show how climatic and geological conditions have changed over time and an interactive map of the geographical distribution of some of the fossil groups featured on the site.
Although the site is a companion to the PBS television show, it also stands on its own as a valuable resource for teachers and students. The site is very well-organized and has clear links between the introductory material 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 transition from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. In particular there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life has resulted in an array of animals, plants and insects. Paleobiology is the study of these creatures within their geological environment, has many advantages over modern observational or research methods of studying evolutionary processes. Paleobiology can examine not only processes and events that happen regularly or over time but also the distribution and frequency of different species of animals across the geological time.
The website is divided into different paths that can be chosen to gain knowledge about evolution. One of these paths, "Evolution 101," walks the reader through the nature and evidence of evolution. The course also focuses on misconceptions about evolution as well as the history of evolutionary thinking.
Each of the other main sections of the Evolution site is equally well created, with resources that support a variety of curriculum levels and pedagogical styles. In addition to the standard textual content, the site also has a wide range of multimedia and interactive content like videos, animations, 에볼루션코리아 and virtual labs. The content is presented in a nested bread crumb fashion that aids navigation and orientation within the large web site.
For instance, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms. Then, it concentrates on a specific clam that can communicate with its neighbors and respond to changes in the water conditions at the level of the reef. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a broad spectrum of topics in evolutionary biology. The content also includes an explanation of the role of natural selection and the concept of phylogenetic analysis, which is an important tool in understanding evolutionary changes.
Evolutionary Theory
For biology students the concept of evolution is a major thread that weaves together all the branches of the field. A wide range of resources supports teaching about evolution across all life sciences.
One resource, the companion to PBS's television series Understanding Evolution is an excellent example of an Web page that provides depth as well as breadth in terms of its educational resources. The site offers a range of interactive learning modules. It also features a nested "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely linked to the world of research science. Animation that introduces the concept of genetics is linked to a page highlighting John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.
The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized into curricula-based paths that correspond to the learning objectives outlined in the biology standards. It includes seven short videos specifically designed for use in the classroom, and 무료 에볼루션, Wifidb.Science, can be streamed for no cost or purchased on DVD.
A number of important questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it happens. This is particularly relevant in the case of human evolution which was a challenge to reconcile religious beliefs that humanity has a special position in the universe and a soul, with the idea that innate physical traits evolved from apes.
There are also a number of other ways in which evolution can occur and natural selection being the most popular theory. Scientists also study other kinds such as genetic drift and sexual selection.
While many scientific fields of study conflict with the literal interpretations of religious texts, evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. Certain religions have reconciled their beliefs to evolution while others haven't.
