What Is The Evolution Site Term And How To Use It
Evolution Site - Teaching About Evolution

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

This rich Web site, a companion to the PBS program that provides teachers with resources that promote evolution education while avoiding the types of misconceptions that can make it difficult to understand. 에볼루션 바카라 's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to effectively teach evolution. Many non-scientists are unable to grasp the concept, and some scientists even employ a definition that confuses it. This is particularly relevant when it comes to the nature of the words themselves.

Therefore, it is important to define terms that are used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful way. It is an accompaniment to the 2001 series, but it is also a resource on its own. The information is presented in a structured way that makes it easy to navigate and comprehend.

The site defines terms such as common ancestor, gradual process and so on. These terms help frame the nature of evolution as well as its relation to other concepts in science. The site then offers an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel the myths that are created by the creationists.

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

Adaptation: The tendency of heritable characteristics to become more adaptable to a specific environment. This is the result of natural selection, which occurs when organisms that are better adapted traits are more likely survive and reproduce than those with less adapted characteristics.

Common ancestor (also known as common ancestor): The most recent ancestor shared by two or more species. By analyzing the DNA from these species, it is possible to identify the common ancestor.

Deoxyribonucleic acid: A huge biological molecule that contains the information required for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be seen in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups which can interbreed), evolve through a series natural changes in the traits of their offspring. The changes can be triggered by a variety of causes, including natural selection, genetic drift and gene pool mixing. The evolution of new species could take thousands of years. Environmental circumstances, such as climate change or competition for food or habitat, can slow or accelerate the process.

The Evolution site tracks the development of a number of different species of plants and animals over time and focuses on the most significant changes that took place in each group's history. It also focuses on human evolution and is a subject that is particularly important for students.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The famous skullcap, along with the bones associated with it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was one year before the first edition of the Origin was published, it is extremely unlikely that Darwin had seen or heard of it.

The site is primarily one of biology however, it also has lots of information about paleontology and geology. The website has a number of features that are particularly impressive, such as the timeline of how geological and climate conditions have changed over time. It also has an interactive map that shows the location of fossil groups.

The site is a companion to a PBS TV series but it can be used as a resource for teachers and students. The site is very well organized and provides clear links between the introduction material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized components of the museum's Web site. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular there are links to John Endler's research with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and has a number of advantages over modern observational and experimental methods in its exploration of evolutionary phenomena. Paleobiology focuses on not only the process and events that occur regularly or over time, but also the distribution and frequency of various animal groups in space throughout the geological time.

The site is divided into several optional paths to learning evolution, including "Evolution 101," which takes the user on a linear path through the scientific process and the evidence supporting the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the history of evolutionary thought.

Each of the main sections on the Evolution website is equally well-developed, and includes materials that are suited to a variety of levels of curriculum and teaching methods. In addition to general textual content, the site offers a wide range of interactive and multimedia resources including videos, animations, and virtual laboratories. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the large web site.

For instance the page "Coral Reef Connections" provides an overview of the relationships between corals and their interaction with other organisms, then concentrates on a specific clam that can 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, gives a good introduction to the many areas of evolutionary biology. The content also includes an overview of the role of natural selectivity and the concept of phylogenetics analysis as a key tool for understanding evolutionary changes.

Evolutionary Theory

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

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


The Evolution Library on this website is a vast multimedia library of resources that are associated to evolution. The content is organized according to curricula-based paths that correspond to the learning objectives set out in the biology standards. It contains seven videos that are designed for classroom use. They can be streamed or purchased as DVDs.

Evolutionary biology is a field of study with a lot of important questions to answer, such as what causes evolution and the speed at which it happens. This is especially relevant to human evolution, where it has been difficult to reconcile the idea that the physical traits of humans were derived from apes and religious beliefs that claim that humans are unique in the universe and has an enviable place in creation with soul.

There are a variety of other ways evolution can take place including natural selection, which is the most popular theory. Scientists also study other types like mutation, genetic drift, and sexual selection.

Many fields of inquiry conflict with literal interpretations of the Bible Evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. Certain religions have reconciled their beliefs with evolution, while others haven't.
