Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution persist. People who have taken in popular science myths often assume that biologists don't believe in evolution.

This site, which is a companion to the PBS series It provides teachers with materials that support evolution education and help avoid the kinds of misconceptions that hinder it. It's laid out in a "bread crumb" format to aid in 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 particularly true when it comes to discussions on the definition of the word itself.

It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site is both an accompaniment to the 2001 series, but it is also a resource on its own. The content is presented in a nested fashion that assists in navigation and orientation.

The site defines terms like common ancestor and 에볼루션 슬롯 the gradual process. These terms help to define the nature and relationship of evolution with other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and validated. This information can be used to dispel myths that have been created by creationists.

You can also consult a glossary that includes terms that are used in evolutionary biology. These terms include:

Adaptation: The tendency of heritable characteristics to become more suitable to a particular setting. This is a result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adapted traits to survive and reproduce.

Common ancestor: The latest common ancestor of two or more distinct species. The common ancestor can be identified by analyzing the DNA of these species.

Deoxyribonucleic Acid: A massive biological molecular containing the information needed for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, called chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is a relationship between two species in which the evolutionary changes of one species influence evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey or host and parasite.

Origins

Species (groups which can interbreed) change through a series natural changes in the traits of their offspring. These changes can be caused by many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of a new species can take thousands of years, and the process may be slowed or increased by environmental factors like climate change or the competition for food or habitat.

The Evolution site traces the emergence of various groups of animals and plants over time and focuses on the most significant shifts that occurred throughout the history of each group. It also explores human evolution as a subject of particular importance for students.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, one year after the first edition of the Origin appeared, 에볼루션 코리아 it is extremely unlikely that Darwin had heard or seen of it.

While the site is focused on biology, it also includes a good deal of information on geology and paleontology. Among the best features of the website are a series of timelines which show the way in which climatic and geological conditions have changed over time, and a map of the distribution of some fossil groups that are featured on the site.

While the site is a companion to the PBS television series however, it can stand on its own as an excellent source for teachers and 에볼루션 슬롯게임 students. The site is well-organized and offers clear links to the introductory content of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features on the museum's website. These hyperlinks make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. In particular there are hyperlinks to John Endler's experiments with Guppies, which demonstrate 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 natural environment and has many advantages over the current observational and experimental methods for analyzing evolutionary processes. In addition to studying processes and events that take place frequently or over a long period of time, paleobiology can be used to study the relative abundance of various species of organisms and their distribution throughout the course of geological time.

The site is divided into different paths that can be chosen to gain knowledge about evolution. One of these paths, "Evolution 101," guides the user through the nature and evidence of evolution. The path also explores common misconceptions about evolution and the evolution theory's history.

Each of the other sections of the Evolution site is equally constructed, with materials that can support a variety of educational levels and pedagogical styles. The site offers a wide array of interactive and multimedia resources that include video clips, animations and virtual laboratories in addition to general textual content. The content is organized in a nested, bread crumb fashion that aids navigation and 에볼루션코리아 orientation within the vast web site.

The page "Coral Reef Connections", for example, gives a brief overview of coral relationships and interactions with other organisms and then zooms in on one clam that is able communicate with its neighbors and 에볼루션 바카라 체험 블랙잭 (discover this info here) react to changes in the water conditions that occur on the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages provides an excellent introduction to a variety of topics in evolutionary biology. The material also provides an explanation of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool for understanding the evolution of change.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A wide range of resources supports teaching about evolution across all life sciences.

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that provides the depth and the broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also has an "bread crumb structure" that assists students in moving away from the cartoon-like style that is used in Understanding Evolution and onto elements on this large website more closely connected to the realms of research science. An animation that introduces the concept of genetics is linked to a page about John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.

Another helpful resource is the Evolution Library on this Web site, which has an extensive library of multimedia resources that are related to evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives outlined in the biology standards. It contains seven videos that are intended for use in the classroom. These can be viewed online or purchased as DVDs.

Many important questions remain at the core of evolutionary biology, including what causes evolution to occur and how fast it occurs. This is particularly relevant for the evolution of humans where it was a challenge to reconcile religious beliefs that humans have a distinct place in the creation and a soul with the notion that our physical traits were derived from apes.

There are a myriad of other ways evolution could occur, with natural selection as the most well-known theory. Scientists also study other types such as mutation, genetic drift, and sexual selection.

While many scientific fields of inquiry have a conflict with the literal interpretations of religious texts Evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions aren't.
