Evolution Site - Teaching About Evolution

Despite the best efforts by biology teachers, there are still misconceptions about the evolution. People who have been exposed to the nonsense of pop science often believe that biologists claim they do not believe in evolution.

This rich website - companion to the PBS series - provides teachers with materials that promote evolution education and avoids the kinds of misconceptions that undermine it. It's laid out in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It is difficult to properly teach evolution. It is often misunderstood by non-scientists, and even scientists are guilty of using an interpretation that is confusing the issue. This is especially true when it comes to discussions about the meaning of the word itself.

Therefore, it is important to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The site is both an accompaniment to the 2001 series, but also a resource of its own. The information is presented in an organized manner that makes it simpler to navigate and understand.

The site defines terms like common ancestor, the gradual process, and adaptation. These terms help frame the nature of evolution and its relation to other concepts in science. The site then offers an overview of how the concept of evolution has been researched and verified. This information can help dispel the myths created by creationists.

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

Adaptation is the tendency of heritable traits to be more suitable to their environment. This is a result of natural selection, which happens when organisms that are better-adapted traits are more likely to survive and reproduce than those with less adaptable traits.

Common ancestor (also called common ancestor) is the most recent ancestral ancestor shared by two or more species. By studying the DNA of these species it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A large biological molecular containing the necessary information for cell replication. The information is contained in a sequence of nucleotides that are strung together to form long chains, referred to as chromosomes. Mutations are the cause of new genetic information within cells.

Coevolution is a relationship between two species where evolutionary changes of one species are influenced by evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or the parasite and the host.

Origins

Species (groups which can interbreed) change through a series of natural changes in their offspring's traits. These changes are caused by a variety that include natural selection, genetic drift, and mixing of genes. The development of a new species can take thousands of years and the process could be slowed down or speeded up due to environmental conditions, such as climate change or competition for food or 에볼루션 게이밍 habitat.

The Evolution site tracks the development of a variety of groups of animals and 에볼루션 바카라 무료체험 plants over time, 에볼루션바카라 focusing on the major transitions that occurred in each group's history. It also focuses on the evolutionary history of humans and humans, a subject that is particularly important for students to comprehend.

Darwin's Origin was written in 1859, at a time when only a handful of antediluvian fossils of human beings had been discovered. The skullcap that is famous, along with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was published in 1858, a year after the first edition of The Origin. Origin.

The site is primarily a biology site, but it also contains many details on geology and paleontology. The most impressive features on the site are a timeline of events that illustrate how geological and climatic conditions have changed over time and a 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 can also be used as a resource by teachers and students. The site is extremely well-organized and has clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum Web site. These hyperlinks make it easy to transition from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular there are hyperlinks to John Endler's experiments using Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of plants, 에볼루션 블랙잭 animals and insects. Paleobiology, the study of these creatures in their natural environment is a superior method of study over the current observational or experimental methods for studying evolutionary phenomena. Paleobiology is able to study not only the process and events that occur regularly or over time, but also the distribution and frequency of different groups of animals across geological time.

The Web site is divided into a variety of ways to learn about evolution that include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence that supports the theory of evolution. The course also focuses on misconceptions regarding evolution, and the background of evolutionary thought.

Each of the main sections of the Evolution website is equally well-designed, with materials that support a variety levels of curriculum and teaching methods. The site offers a wide array of interactive and multimedia resources that include animations, video clips and virtual laboratories, in addition to its general textual content. The breadcrumb-like structure of the content aids in navigation and orientation on the vast Web site.

For example, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interaction with other organisms. It then zooms in on a single clam that is able to communicate with its neighbors and react to changes in water conditions that occur at the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the website, provide an excellent introduction to a broad variety of topics in evolutionary biology. The information also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis, which is a crucial tool in understanding evolutionary change.

Evolutionary Theory

For biology students the concept of evolution is a major thread that binds all the branches of the field. A wide selection of resources helps teachers teach evolution across the disciplines of life science.

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web site that provides the depth and the breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also has an "bread crumb structure" that helps students move away from the cartoon-like style used in Understanding Evolution and onto elements on this site that are more closely linked to the fields of research science. For example an animation that introduces the concept of genetic inheritance links to a page that focuses on John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

Another resource that is worth mentioning is the Evolution Library on this Web website, which includes an extensive multimedia library of resources that are related to evolution. The content is organized into curricula-based pathways that correspond to the learning objectives set out in biology standards. It contains seven short videos designed for use in classrooms. They can be viewed online or purchased as DVDs.

Evolutionary biology is still an area of study with a lot of important questions to answer, such as what causes evolution and how quickly it occurs. This is particularly relevant for the evolution of humans, where it was difficult to reconcile religious beliefs that held that humans have a distinct place in the creation and a soul with the notion that our physical traits evolved from apes.

Additionally there are a myriad of ways that evolution can occur with natural selection being the most widely accepted theory. Scientists also study other types such as mutation, genetic drift, and sexual selection.

While many fields of scientific inquiry have a conflict with literal interpretations of the Bible, evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, but others haven't.
