Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, misconceptions persist regarding evolution. Pop science fiction has led a lot of people to think that biologists don't believe in evolution.

This rich website - companion to the PBS series It provides teachers with materials that support evolution education and help avoid the kinds of myths that undermine it. It's laid out in the "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 have been guilty of using definitions that confuse the issue. This is especially relevant when it comes to the meaning of the words themselves.

It is important to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient 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 nested fashion which aids navigation and orientation.

The site defines terms like common ancestor and gradual process. These terms help frame the nature of evolution as well as its relationship to other concepts in science. The site also provides an overview of how the concept of evolution has been vetted and validated. This information can help dispel myths that are created by the creationists.

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

Adaptation: The tendency of hereditary traits to become more adaptable to a specific 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 ancestral ancestor shared by two or more species. The common ancestor can be identified by analyzing the DNA of the species.

Deoxyribonucleic Acid: A large biological molecular containing the necessary information for cell replication. The information is stored in nucleotide sequences which are strung into long chains called chromosomes. Mutations are the cause of new genetic information in cells.

Coevolution is the relationship between two species in which the evolutionary changes of one species are influenced by evolutionary changes of the other. Coevolution can be observed in the interactions between predator and prey, or parasites and hosts.

Origins

Species (groups of individuals that are able to interbreed) change through an array of natural changes in the characteristics of their offspring. The changes can be triggered by a variety such as natural selection, genetic drift and 에볼루션 무료 바카라 gene pool mixing. The development of a new species could take thousands of years and the process may be slowed or increased by environmental conditions such as climate change or competition for food or habitat.

The Evolution site tracks through time the evolution of various species of plants and animals and focuses on major 에볼루션 무료 바카라 changes within each group's past. It also focuses on human evolution as a subject that is of particular interest to students.

When Darwin wrote the Origin of Species, 에볼루션코리아 only a handful of antediluvian human fossils 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 recognized as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, a year after the publication of the first edition of The Origin. Origin.

The site is primarily one of biology, but it also contains lots of information about paleontology and geology. The most impressive features on the site are a set of timelines which show how climatic and geological conditions changed over time, as well as an interactive map of the geographical distribution of some fossil groups that are featured on the site.

Although the site is a companion piece to the PBS television series but it also stands on its own as an excellent resource for teachers and students. The site is extremely well organized and provides 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's web site. These links make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are also links to John Endler's experiments with guppies. They demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment and has a number of advantages over the modern observational and research methods for analyzing evolutionary processes. Paleobiology is able to study not only the process and events that happen frequently or over time, but also the distribution and frequency of different species of animals in space throughout geological time.

The site is divided into several paths that can be chosen to study the subject of evolution. One of the paths, "Evolution 101," guides the user through the complexities and evidence of evolution. The path also examines myths about evolution as well as the history of evolutionary thought.

Each of the other sections of the Evolution site is similarly constructed, with materials that support a variety of educational levels and pedagogical styles. In addition to general textual content, the site also has an extensive selection of multimedia and interactive resources like videos, animations and virtual labs. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the vast web site.

The page "Coral Reef Connections", for example, provides a comprehensive overview of the relationships between corals, 에볼루션 게이밍 their interaction with other organisms, and then zooms in to one clam, which is able to 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 interactive and multimedia pages gives a good introduction to many topics in evolutionary biology. The material includes an overview of the significance of natural selectivity and the concept of phylogenetics which is a crucial tool for understanding evolutionary change.

Evolutionary Theory

Evolution is a common thread that runs through all branches of biology. A vast collection of books helps in teaching evolution across the disciplines of life sciences.

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

Another resource that is worth mentioning is the Evolution Library on this web site, which contains an extensive collection of multimedia resources that are related to evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives outlined in the biology standards. It contains seven videos that are designed for use in classrooms. They can be streamed or purchased as DVDs.

A number of important questions remain in the midst of evolutionary biology, such as what causes evolution to occur and how fast it happens. This is especially applicable to human evolution which has made it difficult to reconcile the idea that the innate physical characteristics of humans derived from apes, and the religious beliefs that claim that humans are unique among living things and has a special place in creation. It is a soul.

There are a variety of other ways in which evolution can take place including natural selection, which is the most well-known theory. However scientists also study other kinds of evolution, such as mutation, genetic drift, and sexual selection, among others.

Although many scientific fields of study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been a 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 aren't.
