10 Healthy Evolution Site Habits
Evolution Site - Teaching About Evolution
Despite the best efforts of biology teachers, there are still misconceptions regarding evolution. People who have been exposed to pop science nonsense often assume that biologists claim they do not believe in evolution.
This rich Web site, a companion to the PBS program that provides teachers with resources that promote evolution education while avoiding the types of misconceptions that can undermine it. It's organized in the "bread crumb" format to facilitate navigation and orientation.
Definitions
It's not easy to properly teach evolution. 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 important to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in a straightforward and useful way. The site is a companion site to the series that first aired in 2001, but it is also an independent resource. The material is presented in a nested fashion which aids navigation and 에볼루션 바카라 무료체험 orientation.
The site defines terms like common ancestor and gradual process. These terms help to define the nature of evolution as well as its relationship to other concepts in science. The site also provides an overview of how the concept of evolution has been tested and confirmed. This information can help dispel the myths created by creationists.
You can also access a glossary that contains terms used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to become more suitable to their environment. This is the result of natural selection, which occurs when organisms that are better-adapted traits are more likely survive and reproduce than those with less adaptable characteristics.
Common ancestor (also known as common ancestor) The most recent ancestor shared by two or more species. By analyzing DNA from these species, it is possible to determine the common ancestor.
Deoxyribonucleic Acid: A massive biological molecular containing the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the reason behind the creation of new genetic information inside cells.
Coevolution is a relation between two species, where the evolution of one species are influenced by evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey or parasite and host.
Origins
Species (groups of individuals that are able to interbreed) evolve through a series of natural changes in the characteristics of their offspring. Changes can be caused by various factors, including natural selection, gene drift and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, like climate changes or competition for food resources and habitat can impede or accelerate the process.
The Evolution site tracks the evolution of a number of different species of plants and 에볼루션 코리아 animals over time and focuses on the most significant changes that took place in the history of each group. It also explores human evolution as a subject that is particularly important for students.
When Darwin wrote the Origin in 1859, 에볼루션사이트 only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year after the first edition of the Origin appeared, it is highly unlikely that Darwin had seen or heard of it.
While the site is focused on biology, it also offers a lot of information on geology and paleontology. Among the best features on the site are a timeline of events that show how geological and climatic conditions changed over time, as well as an interactive map of the distribution of a few of the fossil groups featured on the site.
Although the site is a companion piece to a PBS television show but it also stands on its own as an excellent source for teachers and students. The site is extremely well organized and provides clear links between the introductory content in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized components of the museum's Web site. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler’s experiments with guppies that illustrate the importance of ecology in evolutionary theory.
Diversity
The evolution of life on Earth has produced a diversity of plants, 에볼루션 바카라 무료 animals, and insects. Paleobiology is the study of these creatures within their geological environment offers many advantages over modern observational or research methods for studying evolutionary processes. In addition to exploring processes and events that take place frequently or over a long period of time, paleobiology is able to analyze the relative abundance of different kinds of organisms as well as their distribution in space over geological time.
The website is divided into several routes that can be taken to gain knowledge about evolution. One of the paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also reveals common misconceptions about evolution and the evolution theory's history.
Each of the main sections of the Evolution website is equally well-developed, and includes materials that can be used to support a variety of levels of curriculum and teaching methods. The site has a range of interactive and multimedia content that include videos, animations, and virtual labs, in addition to its general textual content. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation within the large web site.
The page "Coral Reef Connections" For instance, it provides an overview of the relationships between corals, their interaction with other organisms and zooms in on one clam that is able communicate with its neighbours and respond to changes in the conditions of the water that occur at the reef level. This page, 에볼루션 바카라 사이트 along with the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a broad variety of topics in evolutionary biology. The information 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 evolution is a crucial thread that binds all branches of the field. A rich collection supports teaching evolution across all disciplines of life science.
One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that provides depth and breadth in its educational resources. The site features a wealth of interactive learning modules. It also features an "bread crumb structure" that assists students in moving away from the cartoon-like style of Understanding Evolution and onto elements on this site that are more closely linked to the fields of research science. An animation that introduces the concept of genetics links to a page that highlights John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.
Another helpful resource is the Evolution Library on this Web site, which contains an extensive collection of multimedia assets connected to evolution. The content is organized in curricula-based paths that correspond to the learning objectives set out in the biology standards. It contains seven videos that are designed for classroom use. These can be viewed online or purchased as DVDs.
Evolutionary biology remains an area of study that poses many important questions, including the causes of evolution and how fast it happens. This is especially true for the evolution of humans where it was a challenge to reconcile religious beliefs that humanity has a unique position in the universe and a soul, with the notion that human beings have innate physical traits originated from apes.
Additionally there are a variety of ways in which evolution could occur and natural selection is the most popular theory. However, scientists also study other kinds of evolution like genetic drift, mutation, and sexual selection, among other things.
While many scientific fields of study are in conflict with literal interpretations found in religious texts, evolution biology has been a source of intense debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions have not.
