Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution remain. 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 which support evolution education and help avoid the kinds of myths that make it difficult to understand. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.
Definitions
It's not easy to effectively teach evolution. Non-scientists often misunderstand the subject and some scientists use a definition which confuses it. This is especially true when it comes to debates about the meaning of the word itself.
As such, it is important to define terms that are used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful manner. The site serves as a companion for the 2001 series, but also a resource on its own. The content is presented in a way that aids navigation and 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 then offers an overview of how the concept of evolution has been vetted and verified. This information can help dispel the myths created by creationists.
You can also access a glossary which contains terms that are used in evolutionary biology. These terms include:
Adaptation is the process of changing hereditary traits to become more suited to the environment. This is due to natural selection. It occurs when organisms that are better-adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.
Common ancestor (also known as common ancestor) is the most recent ancestor that is shared by two or more species. By analyzing the DNA from these species, it is possible to identify the common ancestor.
Deoxyribonucleic Acid: A large biological molecular containing the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. 에볼루션바카라사이트 are responsible for the creation of new genetic information within 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 that can interbreed) change by a series of natural variations in the traits of their offspring. click the next internet site can be caused by a variety of factors, including natural selection, genetic drift, and mixing of gene pools. The development of a new species could take thousands of years, and the process could be slowed down or speeded up by environmental factors like climate change or competition for food or habitat.
The Evolution site traces the emergence of a number of different groups of animals and plants over time, focusing on the major shifts that occurred throughout each group's history. It also examines the evolutionary history of humans and humans, a subject that is crucial for students to understand.
When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. One of them was the infamous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year before the first edition of the Origin appeared, it is extremely unlikely that Darwin had ever heard of it.
The site is mostly one of biology however, it also has many details on paleontology and geology. The website has several features that are especially impressive, including an overview of how climate and geological conditions have changed over the course of time. It also has a map showing the distribution of fossil groups.
The site is a companion for a PBS television series, but it could also be used as an educational resource by teachers and students. The site is well-organized and provides clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features of the museum 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 에볼루션바카라사이트 to John Endler's experiments with guppies, which illustrate the importance ecology in evolutionary theory.
Diversity
The evolution of life has led to a variety of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment, has many advantages over modern observational or experimental methods for exploring evolutionary processes. In addition to studying processes and events that take place regularly or over a long period of time, paleobiology can be used to examine the relative abundance of different groups of organisms and their distribution across the course of geological time.
The Web site is divided into various paths to learning evolution, including "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence that supports the theory of evolution. The path also reveals the most common misconceptions about evolution, as well as the evolution of thought.
Each of the other sections of the Evolution site is similarly constructed, with materials that support a variety of curriculum levels and pedagogical styles. The site includes a variety of multimedia and interactive resources that include videos, animations, and virtual laboratories as well as general textual content. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the vast Web site.
For example the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms, then narrows down to a single clam that can communicate with its neighbors and respond to changes in the water conditions that occur at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages offers a great introduction to the many areas of evolutionary biology. The information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is a crucial method to understand evolutionary change.
Evolutionary Theory
For biology students evolution is a crucial thread that connects all branches of the field. A vast collection of resources supports teaching about evolution across the life sciences.
One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web site that provides depth and broadness in terms of educational resources. The site has a wide array of interactive learning modules. It also has a "bread crumb structure" that allows students to move away from the cartoon style of Understanding Evolution and onto elements on this large website more closely connected to the realms of research science. An animation that introduces students to the concept of genetics, which links to a page about John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad.
The Evolution Library on this website has a huge multimedia library of materials that deal with evolution. The content is organized into courses that are based on curriculum and follow the learning objectives set out in biology standards. It includes seven short videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD.
Evolutionary biology is a field of study with a lot of important questions to answer, such as the causes of evolution and the speed at which it occurs. This is especially relevant to human evolution, where it's been difficult to reconcile that the innate physical characteristics of humans derived from apes and religious beliefs that hold that humanity is unique among living things and holds a a special place in creation with soul.
There are a myriad of other ways in which evolution can take place and natural selection being the most popular theory. However, scientists also study other kinds of evolution, such as mutation, genetic drift and sexual selection, among others.
While many scientific fields of study are in conflict with literal interpretations found in religious texts, evolution biology has been a subject of intense debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, other religions haven't.
