Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. Pop science nonsense has led many people to believe that biologists don't believe evolution.

This rich website - companion to the PBS series It provides teachers with materials that support evolution education and help avoid the kinds of misinformation that can undermine it. It's arranged in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

Evolution is a complicated and 에볼루션 무료체험 카지노 사이트 (Eurodyn2020.Org) difficult subject to teach well. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is particularly relevant when it comes to the meaning of the words themselves.

Therefore, it is crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site serves as an accompanying site for the 2001 series, and also a resource of its own. The content is organized in a manner that makes it easier to navigate and comprehend.

The site defines terms such as common ancestor, gradual process and adaptation. These terms help frame the nature of evolution and its relationship to evolution to other concepts in science. The site then offers an overview of how the concept of evolution has been vetted and validated. This information can be used to dispel the 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: The tendency of hereditary traits to become more adaptable to a specific environment. This is a result of natural selection. It 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 [empty] of two or more distinct species. By studying the DNA of these species it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A large biological molecular that contains the information needed for cell replication. The information is stored in nucleotide sequences, which are strung into long chains called chromosomes. Mutations are the source 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. Coevolution is evident through the interaction between predator and prey, or parasite and hosts.

Origins

Species (groups that can interbreed) change by a series of natural variations in their offspring's traits. The causes of these changes are 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 changes or competition for food resources and habitat can impede or accelerate the process.

The Evolution site traces the emergence of a variety of groups of animals and plants over time, focusing on the major shifts that occurred throughout the evolution of each group's history. It also explores human evolution, which is a topic that is particularly important for students.

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, which is now known to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year after the first edition of the Origin was published, it's extremely unlikely that Darwin had seen or heard of it.

The site is mostly a biology site however it also includes many details on geology and paleontology. Among the best features of the Web site are a timeline of events that show how geological and climatic conditions have changed over time, and an interactive map of the distribution of a few fossil groups listed on the site.

The site is a companion for a PBS television series, but it could also be used as a source for teachers and students. The site is well-organized and provides easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features of the museum website. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has resulted in a variety of animals, plants, and 에볼루션 코리아 insects. Paleobiology is the study of these creatures within their geological context and has numerous advantages over modern observational and experimental methods in its exploration of evolutionary phenomena. In addition to examining processes and 무료 에볼루션 (Visit Homepage) events that take place regularly or over a lengthy period of time, paleobiology can be used to study the relative abundance of various groups of organisms and their distribution across the geological time.

The website is divided into a variety of pathways to understanding evolution that include "Evolution 101," which takes the user on a linear path through the scientific process and the evidence to support the theory of evolution. The course also focuses on common misconceptions about evolution and the history of evolutionary thought.

Each of the main sections on the Evolution website is equally well-developed, and includes materials that are suited to a variety of educational levels and teaching styles. In addition to general textual content, the site offers an extensive selection of interactive and multimedia resources, such as videos, animations, and virtual laboratories. The content is presented in a nested bread crumb style that facilitates navigation and orientation within the vast web site.

For example, the page "Coral Reef Connections" provides an overview of the relationships between corals and [empty] their interaction with other organisms, then narrows down to a single clam that can communicate with its neighbors and react to changes in the water conditions that occur 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 the broad spectrum of topics in evolutionary biology. The content also includes a discussion of the role of natural selection and the concept of phylogenetic analysis, which is a key tool for understanding the evolution of change.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A rich collection supports teaching evolution across the disciplines of life science.

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web page that offers both depth as well as breadth in terms of its educational resources. The site offers a range of interactive learning modules. It also features a "bread crumb structure" that helps students move away from the cartoon-like style of Understanding Evolution and onto elements of this vast website that are closely connected to the worlds of research science. An animation that introduces students to 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 website, which includes an extensive library of multimedia items related to evolution. The content is organized into curricula-based paths that correspond to the learning objectives outlined in the standards for biology. It contains seven videos designed specifically for classroom use, which can be streamed for free or purchased on DVD.

A number of important questions remain at the core of evolutionary biology, including what causes evolution to occur and the speed at which it occurs. This is particularly relevant to human evolution, which has made it difficult to reconcile the idea that the physical traits of humans were derived from apes, and the religions that believe that humans are unique in the universe and has an enviable place in creation with soul.

Additionally, there are a number of ways in which evolution could occur with 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 fields of scientific inquiry are in conflict with literal interpretations of the Bible, evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, others haven't.
