Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, there are still a lot of misconceptions about evolution. People who have been exposed to pop science nonsense often assume that biologists don't believe in evolution.

This rich website - companion to the PBS series offers teachers with resources which support evolution education and avoids the kinds of misinformation that can make it difficult to understand. It's organized in a nested "bread crumb" format for ease of 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 particularly applicable to discussions on the nature of the word.

It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The site is both an accompaniment to the 2001 series, and 에볼루션 카지노 also a resource of its own. The material is presented in a structured manner that makes it simpler to navigate and understand.

The site defines terms like common ancestor and gradual process. These terms help to define the nature of evolution as well as its relationship to other concepts in science. The site gives a comprehensive overview of the manner in which evolution has been tested. This information can be used to dispel misconceptions that have been propagated by creationists.

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

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

Common ancestor: The latest common ancestor of two or more different species. By analyzing the DNA from these species, it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are the source of new genetic information within cells.

Coevolution is the relationship between two species where evolution of one species influence evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey, or parasite and host.

Origins

Species (groups which can interbreed) develop by a series of natural variations in their offspring's traits. The changes can be triggered by a variety that include natural selection, genetic drift and mixing of gene pools. The development of a new species could take thousands of years and the process can be slowed or increased by environmental factors like climate change or the competition for food or habitat.

The Evolution site traces through time the evolution of various groups of animals and plants, focusing on major transitions in each group's past. It also focuses on the evolutionary history of humans, a topic that is particularly important for students to know.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. Among them was the famous skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year after the first edition of the Origin was published, 에볼루션 사이트 it's highly unlikely that Darwin had heard or seen of it.

While the site is focused on biology, it also includes a good deal of information about geology as well as paleontology. The Web site has numerous features that are particularly impressive, including an overview of how geological and climate conditions have changed over time. It also has a map showing the distribution of fossil groups.

While the site is a companion to the PBS television series however, it can stand on its own as an excellent source for teachers and students. The site is well-organized and provides clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's funding) as well as the more specialized features of the museum website. These links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. In particular there are hyperlinks to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to a variety of plants, animals and insects. Paleobiology is the study of these creatures in their geographical context and offers numerous advantages over modern observational and experimental methods in its exploration of evolutionary phenomena. In addition to studying the processes and 에볼루션 슬롯게임 (woodard-gamble-2.Blogbright.net) events that happen regularly or over a lengthy period of time, paleobiology is able to study the relative abundance of different kinds of organisms as well as their distribution in space over the course of geological time.

The website is divided into several optional ways to learn about evolution that include "Evolution 101," which takes the user on a linear path through the science of nature and the evidence supporting the theory of evolution. The path also explores misconceptions regarding evolution, and 에볼루션사이트 the background of evolutionary thought.

Each of the other major sections of the Evolution site is equally well created, with resources that support a variety of different pedagogical levels and curriculum levels. The site offers a wide array of interactive and multimedia content, including animations, video clips and virtual laboratories in addition to general textual content. The content is presented in a nested bread crumb-like fashion that helps with navigation and 에볼루션카지노 orientation on the web site.

The page "Coral Reef Connections", for example, provides an overview of the relationships between corals and their interactions with other organisms, and then is enlarged to show one clam that is able communicate with its neighbors and react to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary, multimedia and [empty] interactive pages on the site, provide an excellent introduction to a wide range of topics in evolutionary biology. The information also includes an explanation of the role of natural selection as well as the concept of phylogenetic analysis, which is a crucial method to understand evolutionary changes.

Evolutionary Theory

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

One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of an Web site that offers both the depth and breadth of its educational resources. The site offers a range of interactive learning modules. It also has a nested "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely linked to the field of research science. For instance an animation that introduces the concept of genetic inheritance links to a page highlighting John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

Another useful resource is the Evolution Library on this web site, which has an extensive library of multimedia items connected to evolution. The content is organized into curricula-based pathways that correspond to the learning objectives outlined in the standards for biology. It contains seven short videos designed for classroom use. These can be streamed or purchased as DVDs.

A variety of crucial questions remain in the midst of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is particularly true for the evolution of humans where it was a challenge to reconcile religious beliefs that humanity has a unique place in creation and a soul with the notion that our physical traits were derived from the apes.

There are also a number of other ways evolution could occur, with natural selection as the most popular theory. Scientists also study other types like mutation, genetic drift and sexual selection.

While many fields of scientific study conflict with the literal interpretations of religious texts, the concept of evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. Certain religions have reconciled their beliefs with evolutionary biology, but others haven't.
