Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misinformation about evolution persist. Pop science nonsense has led people to believe that biologists don't believe evolution.
This rich Web site, which is a companion to the PBS program offers teachers resources that support the evolution of education while avoiding the types of misconceptions which undermine it. It's laid out in a "bread crumb" format to aid in navigation and orientation.
Definitions
It's not easy to effectively teach evolution. It is often misunderstood by non-scientists, and even scientists are guilty of using definitions that confuse the issue. This is especially true when discussing the definition of the words.
As such, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site serves as a companion for the 2001 series, and also a resource on its own. The content is presented in a nested manner that assists in navigation and orientation.
The site defines terms like common ancestor and gradual process. These terms help frame the nature and significance of evolution to other scientific concepts. The website then provides an overview of how the concept of evolution has been vetted and validated. This information will help to dispel the myths that are created by the creationists.
You can also access a glossary that contains terms used in evolutionary biology. These terms include:
Adaptation: The tendency of hereditary traits to become more suitable to a particular setting. This is the result of natural selection, which occurs when organisms with better adapted characteristics are more likely to survive and reproduce than those with less adaptable characteristics.
Common ancestor: The most recent common ancestor of two or more different species. The common ancestor can be identified through analyzing the DNA of the species.
Deoxyribonucleic Acid: A huge biological molecular that holds the necessary information for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, referred to as chromosomes. Mutations are the basis for new genetic information in cells.
Coevolution: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution are the interactions between predator and prey, or the parasite and the host.
Origins
Species (groups of individuals that can interbreed) evolve through an array of natural changes in the characteristics of their offspring. The causes of these changes are many factors, such as natural selection, gene drift and mixing of the gene pool. The development of a new species may take thousands of years and the process may be slowed down or speeded up by environmental conditions such as climate change or the competition for food or habitat.
The Evolution site traces the emergence of various groups of animals and plants over time with a focus on the key changes that took place in each group's history. It also examines the evolutionary origin of humans, a topic that is particularly important for students to comprehend.
When 에볼루션 블랙잭 wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the associated bones, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, a year after the first edition of The Origin.
The site is mostly an online biology resource however it also includes many details on geology and paleontology. The site offers a number of features that are especially impressive, including a timeline of how geological and climate conditions have changed over the course of time. It also includes a map showing the distribution of fossil groups.
The site is a companion for the PBS TV series but it could also be used as an educational resource by teachers and students. mouse click the up coming post is well-organized and offers clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These links facilitate the transition from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world 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 animals, plants, and insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over the modern observational and research methods in its exploration of evolutionary processes. In addition to exploring processes and events that take place regularly or over a long period of time, paleobiology can be used to analyze the relative abundance of different species of organisms and their distribution in space over the geological time.
The site is divided into a variety of pathways to understanding evolution which include "Evolution 101," which takes the user on a linear path through the nature of science and the evidence supporting the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the history of evolutionary thought.
Each of the other major sections of the Evolution site is equally well developed, with materials that support a variety of different pedagogical levels and curriculum levels. In addition to the standard textual content, the site features an extensive selection of interactive and multimedia resources, such as videos, animations and virtual labs. The breadcrumb-like arrangement of the content assists with navigation and orientation on the large Web site.
The page "Coral Reef Connections" For instance, it provides a comprehensive overview of the coral's relationships and interactions with other organisms, and then zooms in on one clam, which can communicate with its neighbors and react to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to many topics in evolutionary biology. The content also includes an overview of the importance of natural selection and the concept of phylogenetic analysis, which is a key tool in understanding evolutionary changes.
Evolutionary Theory
For biology students the concept of evolution is a major thread that binds all branches of the field. A rich collection supports teaching evolution across all life science disciplines.
One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides the depth and breadth of its educational resources. The site offers a range of interactive learning modules. It also has a nested "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this large Web site closer to the world of research science. Animation that introduces the concept of genetics, which links to a page that highlights John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.
The Evolution Library on this website is a vast multimedia library of materials that deal to evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives set out in the standards for biology. It contains seven videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.
Many important questions remain at the core of evolutionary biology, including the factors that trigger evolution and the speed at which it occurs. discover here is particularly relevant in the case of human evolution where it was a challenge to reconcile religious beliefs that humanity has a unique place in the creation and a soul, with the notion that human beings have innate physical traits were derived from the apes.
Additionally there are a myriad of ways in which evolution could be triggered with natural selection being the most widely accepted theory. Scientists also study other types such as mutation, genetic drift and sexual selection.
While many fields of scientific inquiry have a conflict with the literal interpretations of religious texts, evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, others aren't.
