Speak "Yes" To These 5 Evolution Site Tips

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions persist about evolution. People who have absorbed popular science myths often assume that biologists don't believe in evolution.

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

Definitions

It's not easy to properly teach evolution. It is often misunderstood even by non-scientists, and even some scientists are guilty of using definitions that confuse the issue. This is particularly true when discussing the nature of the words themselves.

It is essential to define terms used in evolutionary biology. Understanding Evolution's website does this in a straightforward and 에볼루션 바카라 useful way. The site is a companion to the show that premiered in 2001, but it also functions as an independent resource. The content is presented in a nested manner that assists in navigation and orientation.

The site defines terms such as common ancestor (or common ancestor), gradual process and adaptation. These terms help to define the nature of evolution and its relationship to evolution with other scientific concepts. The site gives a comprehensive overview of the way in which evolution has been tested. This information will help to dispel the myths created by creationists.

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

Adaptation: The tendency of heritable traits to become better suitable to a particular setting. This is a result of natural selection. Organisms that have 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 through analyzing 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, which 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 where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey or host and parasite.

Origins

Species (groups of individuals that can interbreed) change 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 a new species may take thousands of years, and the process can be slowed or increased due to environmental conditions, such as climate change or competition for food or habitat.

The Evolution site traces the emergence of a variety of animal and plant groups through time, focusing on the major changes that took place in the history of each group. It also explores human evolution and is a subject that is particularly important for students.

Darwin's Origin was written in 1859, 에볼루션 슬롯 at a time when only a handful of antediluvian fossils of humans were discovered. The most famous among them was the skullcap and the associated bones 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, which was one year after the first edition of the Origin was published, it is very unlikely that Darwin had heard or 에볼루션 무료체험 seen of it.

The site is mostly one of biology however, it also has a lot of information on paleontology and geology. One of the most appealing features on the site are a series of timelines that show how climatic and geological conditions changed over time, as well as an interactive map of the geographical distribution of some fossil groups listed on the site.

The site is a companion for the PBS TV series but it can also be used as an educational source for teachers and students. The site is well-organized, and provides easy links to the introductory content of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features of the museum website. These links facilitate the transition from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced many species of plants, animals and insects. Paleobiology, the study of these creatures within their natural environment offers many advantages over the current observational or experimental methods of studying evolutionary phenomena. Paleobiology is able to study not only processes and events that happen regularly or over time but also the relative abundance and distribution of different species of animals in space over the course of the geological time.

The website is divided into several optional paths to learning evolution that include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence supporting the theory of evolution. The path also explores the most common misconceptions about evolution, as well as the history of evolutionary thought.

Each of the main sections on the Evolution website is equally well-developed, and includes materials that support a variety educational levels and teaching styles. The site has a range of multimedia and interactive resources that include animations, video clips and virtual labs, in addition to its general textual content. The content is organized in a nested, 에볼루션 룰렛 bread crumb fashion that aids navigation and orientation within the vast web site.

The page "Coral Reef Connections" For instance, it provides an overview of coral relationships and interactions with other organisms and then zooms in to one clam, which is able to communicate with its neighbours and respond to changes in the conditions of the water that occur at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a wide variety of topics in evolutionary biology. The material includes a discussion on the role of natural selectivity and 에볼루션 바카라 사이트 the concept phylogenetics analysis, an important method for understanding the evolution of change.

Evolutionary Theory

For biology students evolution is a crucial thread that binds all the branches of the field. A rich collection supports teaching evolution across the life science disciplines.

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

The Evolution Library on this website is a vast multimedia library of assets related to evolution. The contents are organized into curriculum-based paths that parallel the learning objectives set out in the biology standards. It contains seven videos designed specifically for use in classrooms, and can be streamed for free or purchased on DVD.

A number of important questions remain at the heart of evolutionary biology, such as what causes evolution to occur and how fast it occurs. This is especially true for the evolution of humans, where it was difficult to reconcile religious beliefs that held that humanity has a unique place in creation and a soul, with the idea that innate physical traits evolved from Apes.

Additionally there are a myriad of ways in which evolution could occur with natural selection being the most widely accepted theory. Scientists also study other kinds such as genetic drift, and sexual selection.

While many fields of scientific inquiry have a 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 but others haven't.
