Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. People who have been exposed to pop science nonsense often assume that biologists claim they do not believe in evolution.

This rich Web site - companion to the PBS series It provides teachers with materials that promote evolution education and avoid the kinds of misinformation that can make it difficult to understand. It's laid out in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to teach evolution well. It is often misunderstood by non-scientists, and even some scientists use an interpretation that is confusing the issue. This is particularly applicable to discussions on the nature of the word.

It is therefore important to define the terms used in evolutionary biology. Understanding Evolution's website does this in a straightforward and useful way. The site serves as an accompaniment to the 2001 series, but it is also a resource on its own. The material is presented in a structured way that makes it easy to navigate and comprehend.

The site defines terms like common ancestor, the gradual process, and adaptation. These terms help to define the nature and relationship of evolution with other scientific concepts. The website provides a summary of the way the concept of evolution has been tested. This information can help dispel myths created by creationists.

You can also access a glossary which contains terms 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 with better-adapted traits are more likely than those with less-adapted characteristics to survive and reproduce.

Common ancestor (also known as common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified through analyzing the DNA of those species.

Deoxyribonucleic acid: A massive biological molecule that contains information necessary for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution is a relation between two species in which the evolution of one species influence evolutionary changes of the other. Coevolution is evident in the interactions between predator and prey, or parasite and hosts.

Origins

Species (groups of individuals who can interbreed) evolve through a series of natural changes in the traits 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 could take thousands of years, and the process could be slowed down or speeded up due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site tracks the development of various animal and plant groups through time, focusing on the major transitions that occurred in the history of each group. It also examines the human evolutionary roots and humans, a subject that is particularly important for students to understand.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. One of them was the infamous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was published in 1858, one year after the publication of the first edition of The Origin.

While the site is focused on biology, it also includes a good deal of information about geology and paleontology. The most impressive features of the Web site are a series of timelines that illustrate the way in which climatic and geological conditions changed over time, and an interactive map of the distribution of a few fossil groups that are featured on the site.

Although the site is a companion piece to a PBS television series but it also stands on its own as an excellent source for 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) and the more specialized features of the museum's website. These links make it easier to transition 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 plants, 에볼루션 게이밍 animals, and insects. Paleobiology is the study of these creatures in their geological context offers many advantages over modern observational or research methods for studying evolutionary processes. In addition to examining the processes and events that happen regularly or over a long period of time, paleobiology allows to examine the relative abundance of different kinds of organisms as well as their distribution throughout the geological time.

The site is divided into several routes that can be taken to study the subject of evolution. One of these paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The course also focuses on the most common misconceptions about evolution, 에볼루션 코리아 as well as the evolution theory's history.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that can be used to support a variety of levels of curriculum and teaching methods. In addition to general textual content, the site also has a wide range of multimedia and interactive content including videos, animations and virtual laboratories. The breadcrumb-like arrangement of the content assists with navigation and 에볼루션 코리아 orientation on the large website.

For example, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms, then concentrates on a specific clam that is able to communicate with its neighbors and react to changes in water conditions that take place at the reef level. This page, along with the other multidisciplinary, multimedia, and 에볼루션 룰렛 interactive pages on the site, provide an excellent introduction to the broad variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis, which is a crucial tool in understanding evolutionary changes.

Evolutionary Theory

For biology students, evolution is a key thread that weaves together all branches of the field. A vast collection of books helps in teaching evolution across the disciplines of life sciences.

One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that provides the depth and the wide range of educational resources. The site offers a variety of interactive learning modules. It also has a "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 site that are more closely related to the realms of research science. An animation that introduces the concept of genetics, which links to a page highlighting John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.

Another useful resource is the Evolution Library on this website, which includes an extensive collection of multimedia resources that are related to evolution. The content is organized into curricula-based paths that correspond to the learning objectives outlined in the biology standards. It contains seven short videos that are designed for classroom use. These can be viewed online or purchased as DVDs.

A number of important questions remain in the midst of evolutionary biology, such as the factors that trigger evolution and how fast it happens. This is especially true for human evolution, where it has been difficult to reconcile that the physical characteristics of humans derived from apes, and the religious beliefs that hold that humans are unique in the universe and has an exclusive place in the creation. It is a soul.

There are a variety of other ways in which evolution could occur and natural selection being the most popular theory. Scientists also study other types such as genetic drift and sexual selection.

While many fields of scientific study conflict with the literal interpretations of religious texts, evolution biology has been the subject of intense controversy and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the notions of evolution, others have not.
