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 are saying they don't believe in evolution.

This rich website - companion to the PBS series It provides teachers with materials which support evolution education and avoids the kinds of myths that undermine it. It's organized in the "bread crumb" format to aid in navigation and 에볼루션코리아 orientation.

Definitions

It's difficult to teach evolution well. People who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. This is particularly true when it comes to discussions about the nature of the word.

It is therefore important to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a simple and 에볼루션 바카라 사이트 efficient manner. The site serves as an accompanying site for the 2001 series, but also a resource on its own. The material is presented in a structured manner that makes it simpler to navigate and understand.

The site defines terms such as common ancestor (or common ancestor), gradual process and adaptation. These terms help frame the nature and 에볼루션코리아 significance of evolution with other scientific concepts. The site also provides an overview of how the concept of evolution has been researched and validated. This information can be used to dispel misconceptions that have been propagated by creationists.

It is also possible to access the glossary of terms used in evolutionary biology. These terms include:

Adaptation is the tendency of hereditary traits to become better suited to an environment. This is a result of natural selection. Organisms with better-adapted characteristics are more likely than those with less adapted characteristics to survive and reproduce.

Common ancestor (also called common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of the species.

Deoxyribonucleic Acid: A large biological molecular that contains the information required 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 is a relation between two species in which the evolutionary changes of one species influence evolutionary changes in the other. Coevolution can be seen in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups which can interbreed) change through a series of 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 new species can take thousands of years. Environmental conditions, like climate change or competition for food resources and habitat can impede or 에볼루션 바카라 체험 accelerate the process.

The Evolution site traces the emergence of a variety of groups of animals and plants over time and focuses on the most significant transitions that occurred in the evolution of each group's history. It also examines the evolution of humans, which is a topic that is of particular interest to students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The famous skullcap, with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was a year before the first edition of the Origin was published, it is highly unlikely that Darwin had ever heard of it.

While the site is focused on biology, it includes a good deal of information about geology as well as paleontology. The website has numerous features that are especially impressive, including an overview of the way that climate and geological conditions have changed over the course of time. It also includes a map showing the distribution of fossil groups.

While the site is a companion to the PBS television show however, it can stand on its own as an excellent resource 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 assistance) and the more specific features of 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 links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced a variety of animals, plants and insects. Paleobiology, the study of these creatures in their geological context offers many advantages over the current observational or experimental methods for studying evolutionary processes. Paleobiology is able to study not only processes and events that occur frequently or over time, but also the distribution and frequency of different groups of animals in space throughout the geological time.

The site is divided into a variety of pathways to understanding evolution that include "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 explores misconceptions about evolution, as well as the history of evolutionary thought.

Each of the other main sections of the Evolution site is equally well developed, with materials that support a variety of different pedagogical levels and curriculum levels. The site offers a wide array of interactive and multimedia content, including video clips, 에볼루션 사이트 animations and virtual laboratories, 에볼루션코리아 in addition to its general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the large website.

For instance the page "Coral Reef Connections" provides an overview of coral relationships and their interaction with other organisms. Then, it 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, multimedia and interactive pages on the website, provide an excellent introduction to the broad spectrum of topics in evolutionary biology. The content also includes an explanation of the role 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 key thread that weaves together all the branches of the field. A wide selection of resources helps teachers teach evolution across all disciplines of life science.

One resource, a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that offers both depth and breadth in its educational resources. The site offers a variety of interactive learning modules. It also features an "bread crumb structure" that helps students move away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely linked to the worlds of research science. An animation that introduces the concept of genetics links to a page that highlights John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad.

Another useful resource is the Evolution Library on this Web website, which includes an extensive collection of multimedia assets that are related to evolution. The content is organized into curriculum-based paths that parallel the learning objectives set out in biology standards. It contains seven videos that are designed for use in classrooms. They can be viewed online or purchased as DVDs.

Many important questions remain at the heart of evolutionary biology, such as what triggers evolution and how fast it occurs. This is especially relevant to human evolution, where it has been difficult to reconcile the notion that the physical traits of humans evolved from apes, and the religions that believe that humans are unique among living things and has an enviable place in creation with soul.

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

While many fields of scientific inquiry are in conflict with the literal interpretations of religious texts evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, while others haven't.
