Why All The Fuss Over Evolution Site

Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, there are still a lot of misconceptions about evolution. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.

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

Definitions

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

As such, it is essential to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site is a companion site to the series that first aired in 2001, but also functions as an independent resource. The information is presented in a structured way that makes it easy 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 relationship to evolution to other scientific concepts. The site provides an overview of the manner in which evolution has been tested. This information will help to dispel the myths created by creationists.

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

Adaptation: The tendency for heritable traits to become better adaptable to a specific environment. This is due to natural selection. It occurs when organisms with more adaptable traits are more likely survive and reproduce than those with less adaptable traits.

Common ancestor (also called common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified by studying the DNA of these species.

Deoxyribonucleic acid: A large biological molecule that holds the information required for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form long chains, called chromosomes. Mutations are the cause of new genetic information in cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution is evident in the interaction of 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 triggered by a variety of causes, including natural selection, genetic drift, and mixing of genes. The development 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 competition for food or habitat.

The Evolution site traces through time the evolution of different species of plants and animals, focusing on major 에볼루션바카라 transitions in each group's past. It also examines the evolutionary history of humans, a topic that is especially important for students to understand.

Darwin's Origin was published in 1859, when only a handful of antediluvian fossils of human beings had been discovered. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany, which is now known as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, one year after the first edition of the Origin was published, it's very unlikely that Darwin had ever heard of it.

While the site focuses on biology, it also includes a good deal of information about geology as well as paleontology. Among the best features on the site are a set of timelines which show the way in which climatic and geological conditions have changed over time and an interactive map of the distribution of some fossil groups that are featured on the site.

The site is a companion for a PBS television series, but it can be used as a source 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 elements of the museum's web site. These hyperlinks make it easy 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 research with Guppies that 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 within their geological context and has numerous advantages over modern observational and experimental methods in its exploration of evolutionary processes. In addition to studying the processes and events that happen regularly or over a lengthy period of time, 에볼루션 바카라 체험 paleobiology allows to examine the relative abundance of different kinds of organisms as well as their distribution in space over the course of geological time.

The site is divided into various ways to learn about evolution which include "Evolution 101," which takes the user on a linear path through the nature of science and the evidence to support the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that support a variety curriculum levels and teaching styles. In addition to the standard textual content, the site also has an array of interactive and multimedia resources like videos, animations, and virtual laboratories. The content is presented in a nested bread crumb-like fashion that helps with navigation and orientation on the web site.

For example the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interaction with other organisms, then narrows down to a single clam that is able to communicate with its neighbours and respond to changes in the water conditions that occur at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to a wide range of topics in evolutionary biology. The content includes an overview of the significance of natural selectivity and the concept of phylogenetics which is a crucial method for understanding the evolution of change.

Evolutionary Theory

Evolution is a common thread that connects all branches of biology. A rich collection of resources supports teaching about evolution across all life sciences.

One resource, a companion to the PBS television series Understanding Evolution, 에볼루션 바카라 무료체험 is an excellent example of an Web site that offers both depth and breadth in its educational resources. The site features a wide range of interactive learning modules. It also has an encased "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this large Web site closer to the world of research science. For instance an animation that explains the notion of genetic inheritance leads to a page highlighting John Endler's experiments in 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 to evolution. The content is organized in curriculum-based pathways that correspond to the learning goals set forth in the standards for biology. It contains seven videos that are designed for 바카라 에볼루션 use in classrooms. These can be viewed online or purchased as DVDs.

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

There are a myriad of other ways evolution can take place and natural selection being the most widely accepted theory. Scientists also study other types such as genetic drift, and sexual selection.

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