Evolution Site - Teaching About Evolution

Despite the best efforts by biology teachers, there are still misconceptions about the evolution. Pop science nonsense has led many people to believe that biologists don't believe evolution.

This rich website - companion to the PBS series It provides teachers with materials which support evolution education and help avoid the kinds of misconceptions that hinder it. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

Evolution is a complex and 에볼루션바카라사이트 challenging subject to teach well. Non-scientists often misunderstand the subject and some scientists use a definition that confuses it. This is especially relevant to discussions about the meaning of the word itself.

It is therefore important to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. It is an accompaniment to the 2001 series, and 에볼루션 블랙잭 it is also a resource on its own. The content is organized in a manner that makes it simpler to navigate and comprehend.

The site defines terms like common ancestor and the gradual process. These terms help frame the nature and relationship of evolution to other scientific concepts. The site gives a comprehensive overview of the ways the concept of evolution has been tested. This information can be used to dispel myths that have been engendered by creationists.

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

Adaptation is the process of changing hereditary traits to become more suited to the environment. This is a result of natural selection, which happens when organisms that have more adaptable traits are more likely to survive and reproduce than those with less adaptable characteristics.

Common ancestor (also called common ancestor): The most recent ancestor 에볼루션 코리아 룰렛 - Lovewiki.faith - shared by two or more species. The common ancestor can be identified by studying the DNA of those species.

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

Coevolution is a relationship between two species where evolution of one species are influenced by evolutionary changes of the other. Examples of coevolution are the interactions between predator and prey or 에볼루션 바카라 host and parasite.

Origins

Species (groups of individuals who can interbreed) change through natural changes in the characteristics of their offspring. Changes can be caused by various factors, including natural selection, gene drift, and mixing of the gene pool. The development of a new species can take thousands of years, and the process can be slowed down or speeded up due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site traces the emergence of a number of different animal and plant groups through time and focuses on the most significant changes that took place in the history of each group. It also examines the human evolutionary roots which is especially important for students to comprehend.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans were discovered. Among them was the famous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just a year before the first edition of the Origin appeared, it is very unlikely that Darwin had ever heard of it.

The site is mostly a biology site, but it also contains a lot of information on geology and paleontology. The Web site has several features that are particularly impressive, such as an overview of how climate and geological conditions have changed over the course of time. It also features a map showing the distribution of fossil groups.

The site is a companion for the PBS television series, but it can also be used as a resource by 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 sophisticated elements of the museum 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. There are links to John Endler's experiments with guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geographical context and offers many advantages over modern observational and experimental methods in its exploration of evolutionary processes. In addition to studying the processes and events that happen frequently or over a long period of time, paleobiology can be used to examine the relative abundance of various kinds of organisms as well as their distribution across the course of geological time.

The site is divided into various pathways to understanding 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 about evolution, as well as the history of evolutionary thought.

Each of the other main sections of the Evolution site is similarly created, with resources that can support a variety of curriculum levels and pedagogical styles. In addition to general textual content, the site offers an array of interactive and multimedia resources including video clips, animations, and virtual laboratories. The content is laid out in a nested bread crumb style that facilitates navigation and orientation on the web site.

The page "Coral Reef Connections" For instance, it gives a brief overview of coral relationships and their interactions with other organisms and then zooms in on a single clam, which can communicate with its neighbors and react to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a broad spectrum 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 key tool for understanding the evolution of change.

Evolutionary Theory

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

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides depth as well as broadness in terms of educational resources. The site offers a variety of interactive learning modules. It also has a nested "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the world of research science. An animation that introduces the concept of genetics, which links to a page highlighting John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad.

The Evolution Library on this website contains a large multimedia library of resources that are associated with evolution. The content is organized according to courses that are based on curriculum and follow the learning objectives outlined in biology standards. It includes seven short videos that are designed for use in classrooms. These are available to stream or purchase as DVDs.

A number of important questions remain at the core of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is especially true in the case of human evolution where it was a challenge to reconcile religious beliefs that humans have a distinct place in creation and a soul with the notion that our physical traits were derived from Apes.

Additionally there are a variety of ways that evolution could be triggered and natural selection is the most popular theory. Scientists also study other types like mutation, genetic drift and sexual selection.

While many fields of scientific inquiry have a conflict with literal interpretations of the Bible evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution but others haven't.
