Evolution Site - Teaching About Evolution

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

This rich Web site - companion to the PBS series offers teachers with resources that promote evolution education and avoid the kinds of misinformation that can undermine 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 difficult subject matter to teach well. It is often misunderstood by non-scientists, and even scientists use a definition that confuses the issue. This is especially relevant when discussing the meaning of the words themselves.

It is therefore crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The site is both a companion for the 2001 series, but also a resource of its own. The content is presented in an organized manner that makes it simpler to navigate and comprehend.

The site defines terms like common ancestor, gradual process and so on. These terms help to define the nature of evolution and its relation to other concepts in science. The website provides a summary of the way that evolution has been examined. 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 tendency of hereditary traits to become more suitable to their environment. This is a result of natural selection. Organisms with better-adapted characteristics are more likely than those with less adaptable traits to survive and reproduce.

Common ancestor: The latest common ancestor of two or more different species. The common ancestor can be identified by analyzing the DNA of the species.

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

Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be observed through the interaction between predator and prey, or parasite and hosts.

Origins

Species (groups that can crossbreed) develop through a series of natural changes in the traits of their offspring. These changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, such as climate changes or competition for food resources and habitat can slow or speed up the process.

The Evolution site tracks through time the evolution of various groups of animals and plants with a focus on major changes within each group's past. It also focuses on the human evolutionary roots and 에볼루션 바카라 무료체험 humans, a subject that is especially important for students to understand.

When Darwin wrote the Origin of Species, 에볼루션 바카라 무료체험 only a handful of antediluvian human fossils had been found. One of them was the infamous skullcap and the associated bones discovered in 1856 at 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 before the first edition of the Origin appeared, it is highly unlikely that Darwin had ever heard of it.

The site is primarily one of biology however it also includes many details on geology and paleontology. The most impressive features on the site are a set of timelines that show how geological and climatic conditions have changed over time and a map of the distribution of a few of the fossil groups featured on the site.

While the site is a companion piece to a PBS television show but it also stands on its own as a great resource for teachers and students. The site is well-organized, and provides clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) and 에볼루션 바카라 무료체험 the more specialized features on the museum's website. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are hyperlinks to John Endler's experiments with guppies that illustrate 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 numerous advantages over modern observational and 에볼루션 바카라 experimental methods in its exploration of evolutionary phenomena. Paleobiology can examine not only the process and events that happen regularly or over time but also the distribution and frequency of different groups of animals in space over the course of the geological time.

The site is divided up into several options to learn about evolution. One of these paths, "Evolution 101," guides the user through the evolution of nature and the evidence of evolution. The path also explores misconceptions about evolution and also the history of evolutionary thinking.

Each of the main sections on the Evolution website is equally well-designed, with materials that support a variety educational levels and teaching styles. The site has a range of interactive and multimedia content that include videos, animations, and virtual labs in addition to general textual content. The breadcrumb-like arrangement of the content helps with navigation and orientation on the massive web site.

For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships and their interaction with other organisms. It then concentrates on a specific clam that can communicate with its neighbors and react to changes in water conditions at the level of the reef. This page, as well as the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to many topics in evolutionary biology. The material includes an overview of the importance of natural selection and the concept of phylogenetics analysis as a key tool for understanding evolutionary change.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A rich collection of resources helps teachers teach about evolution across all life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that offers both 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 assists students in moving away from the cartoon style used in Understanding Evolution and onto elements on this large website more closely linked to the fields of research science. An animation that introduces students to the concept of genetics, which links to a page highlighting John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.

Another useful resource is the Evolution Library on this web site, which has an extensive multimedia library of resources that are related to evolution. The content is organized according to curricula-based paths that correspond to the learning objectives set out in the standards for biology. It contains seven videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.

A variety of crucial questions remain at the heart 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 held that humans have a distinct place in creation and a soul, with the notion that human beings have innate physical traits originated from Apes.

Additionally there are a myriad of ways that evolution can occur with natural selection being the most widely accepted theory. However, scientists also study other kinds of evolution, such as genetic drift, mutation, and sexual selection, among other things.

While many scientific fields of inquiry are in conflict with literal interpretations of religious texts, evolutionary biology has been the subject of particularly intense controversy and 에볼루션 바카라 무료체험 에볼루션 바카라 사이트 체험 (Fewpal.com) resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
