Evolution Site - Teaching About Evolution

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

This rich website - companion to the PBS series offers teachers with resources which support evolution education and avoid the kinds of myths that hinder it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It is difficult to teach evolution well. It is often misunderstood by non-scientists and even some scientists are guilty of using an interpretation that is confusing the issue. This is especially applicable to discussions on the meaning of the word itself.

As such, it is important to define terms that are used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful manner. The site is a companion to the show that premiered in 2001, but also functions as an independent resource. The information is organized in a manner that makes it simpler to navigate and understand.

The site defines terms such as common ancestor, gradual process and so on. These terms help to frame the nature of evolution as well as its relationship to other scientific concepts. The site also provides an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel myths created by creationists.

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

The process of adaptation is the tendency of heritable traits to be more suitable to their environment. This is the result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less adaptable traits to survive and reproduce.

Common ancestor: The most recent common ancestor of two or more distinct species. By analyzing the DNA from these species it is possible to identify the common ancestor.

Deoxyribonucleic acid: A large biological molecule that contains information required for cell replication. The information is stored in a sequence of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the source of new genetic information in cells.

Coevolution is a relationship between two species where evolution of one species are influenced evolutionary changes of the other. Coevolution is evident through the interaction between predator and prey, or 에볼루션 코리아 parasites and hosts.

Origins

Species (groups of individuals who can interbreed) evolve through a series of natural changes in the characteristics of their offspring. The changes can be caused by a variety of causes that include natural selection, genetic drift, and mixing of genes. The evolution of new species can take thousands of years. Environmental conditions, like climate changes or competition for food or habitat can impede or accelerate the process.

The Evolution site tracks through time the emergence of various animal and plant groups, focusing on major transitions in each group's past. It also focuses on human evolution, which is a topic of particular importance to students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The famous skullcap, 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. While the skullcap wasn't published until 1858, which was one year after the first edition of the Origin was published, it's very unlikely that Darwin had heard or seen of it.

While the site focuses on biology, it offers a lot of information about geology and paleontology. Among the best features of the Web site are a set of timelines that illustrate how climatic and geological conditions have changed over time, as well as an outline of the geographical distribution of some fossil groups that are featured on the site.

While the site is a companion piece to a PBS television series however, it can stand on its own as an excellent source for teachers and students. The site is extremely well organized and 에볼루션카지노 provides clear links between the introductory content 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 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 using Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced many species of plants, animals and insects. Paleobiology is the study of these creatures in their geological context is a superior method of study over the current observational or experimental methods for exploring evolutionary phenomena. Paleobiology focuses on not only processes and events that occur regularly or over time but also the distribution and frequency of different groups of animals in space over the course of geological time.

The site is divided into several routes that can be taken to study the subject of evolution. One of the paths, "Evolution 101," walks the reader through the nature and evidence of evolution. The path also examines myths about evolution, as well as the history of evolutionary thinking.

Each of the other main sections of the Evolution site is similarly developed, with materials that support a variety of educational levels and pedagogical styles. The site includes a variety of multimedia and interactive resources, including video clips, animations and virtual labs, in addition to its general textual content. The breadcrumb-like organization of the content assists with navigation and orientation on the massive website.

The page "Coral Reef Connections" For instance, it provides an overview of the relationships between corals, their interaction with other organisms, and then is enlarged to show one clam that can communicate with its neighbors and respond to changes in conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a broad range of topics in evolutionary biology. The information also includes a discussion of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool in understanding evolutionary changes.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A rich collection supports teaching evolution across the disciplines of life science.

One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both the depth and breadth of its educational resources. The site has a variety of interactive learning modules. It also features a "bread crumb structure" that assists students in moving away from the cartoon-like style used in Understanding Evolution and 에볼루션 카지노 - click the up coming post - onto elements on this site that are more closely linked to the worlds of research science. For example, 에볼루션게이밍 an animation introducing the idea of genetic inheritance connects to a page highlighting John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

Another helpful resource is the Evolution Library on this Web site, which has an extensive multimedia library of assets related to evolution. The contents are organized into curriculum-based paths that parallel the learning objectives set out in biology standards. It contains seven videos designed for classroom use. These can be streamed or purchased as DVDs.

Many important questions remain at the core of evolutionary biology, including what triggers evolution and the speed at which it occurs. This is particularly relevant for the evolution of humans where it was a challenge to reconcile religious beliefs that humanity has a special place in the creation and a soul with the idea that innate physical traits were derived from the apes.

There are also a number of other ways evolution could occur, with natural selection as the most widely accepted theory. However, scientists also study other types of evolution such as mutation, genetic drift, and sexual selection, among other things.

While many scientific fields of inquiry are in conflict with the literal interpretations of religious texts, evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution but others haven't.
