Evolution Site - Teaching About Evolution

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

This site, which is a complement to the PBS program that provides teachers with resources which support evolution education, while avoiding the kinds of misconceptions which undermine it. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It's not easy to properly teach evolution. Non-scientists often misunderstand the subject and some scientists employ a definition that confuses it. This is especially true when discussing the nature of the words themselves.

It is therefore important to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. The site is a companion to the series that first aired in 2001, but it can also function as an independent resource. The content is presented in a nested fashion that aids navigation and orientation.

The site defines terms like common ancestor (or common ancestor), gradual process and adaptation. These terms help define the nature of evolution and 에볼루션 바카라 무료체험 카지노 [79Bo1.com] its relationship to evolution to other scientific concepts. The site provides an overview of the ways that evolution has been tested. This information can be used to dispel the myths that have been engendered by the creationists.

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

Adaptation is the process of changing hereditary traits to become more suitable to their environment. This is due to natural selection, which occurs when organisms with more adaptable traits are more likely survive and reproduce than those with less adapted traits.

Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified by studying the DNA of those species.

Deoxyribonucleic acid: A huge biological molecule that contains the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are the basis for new genetic information within cells.

Coevolution is the relationship between two species where evolutionary changes of one species are influenced evolutionary changes of the other. Coevolution can be seen through the interaction between predator and prey, or parasites and hosts.

Origins

Species (groups that can interbreed) develop through a series natural changes in their offspring's traits. The changes can be caused by a variety of causes, including natural selection, genetic drift, and mixing of genes. The evolution of a new species could take thousands of years, and the process can be slowed down or accelerated due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site follows the emergence of various groups of animals and plants and focuses on major changes in each group's history. It also examines the evolutionary origin of humans which is especially important for 에볼루션 무료 바카라 students to comprehend.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just a year before the first edition of the Origin was published, 에볼루션 코리아 it is extremely unlikely that Darwin had seen or heard of it.

The site is primarily an online biology resource however it also includes lots of information about paleontology and geology. The Web site has a number of features that are particularly impressive, including an overview of the way that climate and geological conditions have changed over the course of time. It also features an interactive map that shows the location of fossil groups.

Although the site is a companion to a PBS television series, it also stands on its own as an excellent resource for teachers and students. The site is well-organized, and provides clear links to the introductory content of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized features of the museum's website. These hyperlinks facilitate the move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. There are also links to John Endler's experiments with guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of plants, animals and insects. Paleobiology is the study of these creatures within their geological context and has a number of advantages over the modern observational and research methods for analyzing evolutionary processes. Paleobiology is able to study not only processes and events that occur regularly or over time, but also the relative abundance and distribution of different groups of animals in space over the course of geological time.

The website is divided into several options to learn about evolution. One of these paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The path also explores misconceptions regarding evolution, and also the history of evolutionary thinking.

Each of the other main sections of the Evolution site is equally constructed, with materials that can be used to support a range of educational levels and pedagogical styles. The site offers a wide array of multimedia and interactive resources that include animations, video clips and virtual labs as well as general textual content. The breadcrumb-like arrangement of the content helps with navigation and orientation on the large website.

The page "Coral Reef Connections", for example, provides an overview of the coral's relationships and their interactions with other organisms, and then zooms in to a single clam, which is able to communicate with its neighbours and respond to changes in the water conditions that occur on the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, offers a great introduction to a variety of topics in evolutionary biology. The content also includes an overview of the importance of natural selection and the concept of phylogenetic analysis which is an important tool for understanding the evolution of changes.

Evolutionary Theory

For biology students the concept of evolution is a major thread that connects all the branches of the field. A rich collection of resources supports teaching about evolution across the life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of a Web site that provides the depth and breadth of its educational resources. The site features a wealth of interactive learning modules. It also features a "bread crumb structure" that helps students move away from the cartoon style that is used in Understanding Evolution and onto elements of this vast website that are closely related to the worlds of research science. For instance an animation that introduces the idea of genetic inheritance connects to a page highlighting John Endler's experiments with artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website contains a large multimedia library of materials that deal with evolution. The content is organized in curriculum-based pathways that correspond to the learning goals set forth in biology standards. It includes seven short videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.

A variety of crucial questions remain in the midst of evolutionary biology, including what triggers evolution and how fast it happens. This is particularly true in the case of human evolution where it was a challenge to reconcile religious beliefs that held that humanity has a unique place in creation and a soul, with the notion that our physical traits were derived from apes.

In addition there are a variety of ways that evolution could be triggered with natural selection being the most popular theory. Scientists also study other types such as mutation, genetic drift and sexual selection.

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