The Little Known Benefits Of Evolution Site
Evolution Site - Teaching About Evolution
Despite the best efforts by biology teachers, there are still misconceptions about evolution. Pop science nonsense has led many people to believe that biologists don't believe evolution.
This rich Web site - companion to the PBS series It provides teachers with materials that support evolution education and avoids the kinds of myths that undermine it. It's organized in a nested "bread crumb" format to make it easy for navigation and orientation.
Definitions
It's not easy to effectively teach evolution. It is often misunderstood even by non-scientists, and even scientists have been guilty of using definitions that confuse the issue. This is particularly true when discussing the nature of the words themselves.
It is essential to define terms used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful manner. The site serves as an accompanying site for 에볼루션 룰렛 the 2001 series, but also a resource of its own. The content is presented in a nested manner that aids navigation and orientation.
The site defines terms like common ancestor and gradual process. These terms help define the nature and significance of evolution to other scientific concepts. The site then offers an overview of how the concept of evolution has been researched and confirmed. This information can be used to dispel myths that have been engendered by the creationists.
It is also possible to access a glossary of terms used in evolutionary biology. These terms include:
The process of adaptation is the tendency of heritable traits to be better suited to an environment. This is a result of natural selection. Organisms that have better-adapted traits are more likely than those with less adaptable traits to reproduce and survive.
Common ancestor (also known as common ancestor): The most recent ancestral ancestor shared by two or more species. By studying the DNA of these species it is possible to identify the common ancestor.
Deoxyribonucleic Acid: A large biological molecular that holds the necessary information for cell replication. The information is stored in nucleotides arranged in sequences 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 influenced by evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey or parasite and host.
Origins
Species (groups of individuals that are able to interbreed) develop through natural changes in the traits of their offspring. Changes can be caused by numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, such as climate change or competition for food and habitat can impede or accelerate the process.
The Evolution site follows the emergence of various species of plants and animals with a focus on major 에볼루션코리아 changes in each group's history. It also focuses on the human evolutionary roots, 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. The skullcap that is famous, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. Although the skullcap was not published until 1858, a year before the first edition of the Origin was published, it's extremely unlikely that Darwin had seen or heard of it.
While the site focuses on biology, it offers a lot of information about geology and paleontology. One of the most appealing features of the website are a timeline of events that illustrate how climatic and geological conditions changed over time, as well as a map of the distribution of a few of the fossil groups featured on the site.
While the site is a companion piece to the PBS television series, it also stands on its own as an excellent source for teachers and students. The site is well organized and provides clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. 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 has resulted in an array of plants, animals and insects. Paleobiology, the study of these creatures within their geological context offers many advantages over modern observational or research methods of studying evolutionary phenomena. In addition to examining processes and events that take place frequently or over a long period of time, paleobiology is able to examine the diversity of groups of organisms and their distribution across geological time.
The website is divided into several routes that can be taken to learn about evolution. One of the paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The path also examines myths about evolution, and the background of evolutionary thinking.
Each of the other sections of the Evolution site is equally well developed, with materials that support a variety of curriculum levels and pedagogical styles. In addition to general textual content, the site features an array of interactive and multimedia resources, 에볼루션 such as video clips, animations, and virtual labs. The breadcrumb-like arrangement of the content assists with navigation and orientation on the massive Web site.
The page "Coral Reef Connections" For instance, it provides an overview of the relationships between corals and their interactions with other organisms and zooms in to one clam, which can 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 site, provide an excellent introduction to a wide spectrum of topics in evolutionary biology. The content includes an overview of the role of natural selectivity and the concept of phylogenetics analysis as a key tool for understanding evolutionary changes.
Evolutionary Theory
Evolution is an underlying thread that runs through all branches of biology. A rich collection of resources supports teaching about evolution across the life sciences.
One resource, 에볼루션 슬롯 which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that provides depth and broadness in terms of educational resources. The site offers a range of interactive learning modules. It also has a "bread crumb structure" that allows students to move away from the cartoon-like style of Understanding Evolution and onto elements on this large website more closely related to the realms of research science. Animation that introduces the concept of genetics is linked to a page highlighting John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.
The Evolution Library on this website has a huge multimedia library of resources that are associated to evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning objectives set out in the standards for biology. It includes seven short videos designed specifically for use in the classroom, and can be streamed for no cost or purchased on DVD.
Many important questions remain in the midst of evolutionary biology, including what triggers evolution and the speed at which it occurs. This is particularly relevant for humans' evolution where it was a challenge to reconcile religious beliefs that humans have a distinct place in creation and a soul, with the idea that innate physical traits were derived from the apes.
Additionally, there are a number of ways that evolution can be triggered with natural selection being the most popular theory. However, scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among others.
While many fields of scientific study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the theories of evolution, others haven't.
