Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution persist. 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 avoids the kinds of misconceptions that make it difficult to understand. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and challenging subject to teach effectively. Many non-scientists are unable to grasp the concept and some scientists use a definition which confuses it. This is especially true when discussing the definition of the words.

It is essential to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The website is a companion to the show that premiered in 2001, but it is also an independent resource. The material is presented in an organized manner that makes it simpler to navigate and comprehend.

The site defines terms like common ancestor and the gradual process. These terms help define the nature and relationship of evolution to other scientific concepts. The site provides an overview of the way in which evolution has been examined. This information can help dispel myths that are created by the creationists.

You can also consult a glossary that includes 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, which occurs when organisms with better-adapted traits are more likely survive and reproduce than those with less adaptable traits.

Common ancestor: The latest common ancestor of two or more distinct species. The common ancestor can be identified through analyzing the DNA of those species.

Deoxyribonucleic acid: A large biological molecule that contains the information necessary for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution: A relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution include the interaction between predator and prey, or the parasite and 에볼루션카지노 the host.

Origins

Species (groups of individuals that can interbreed) develop through an array of natural changes in the traits of their offspring. 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 circumstances, such as climate change or competition for food resources and habitat can slow or speed up the process.

The Evolution site traces through time the evolution of various species of plants and animals, focusing on major transitions in each group's past. It also focuses on the human evolutionary roots which is especially important for students to know.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was published in 1858, which was a year following the initial edition of The Origin.

While the site is focused on biology, it offers a lot of information about geology as well as paleontology. One of the most appealing features of the Web site are a series of timelines that show how geological and climatic conditions have changed over time and an interactive map of the geographical distribution of some fossil groups listed on the site.

While the site is a companion piece to a PBS television series, it also stands on its own as a great resource for teachers and students. The site is extremely well organized and provides clear links between the introductory information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific components of the museum's Web site. These hyperlinks make it easier to transition from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler’s experiments with guppies. They illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, 에볼루션카지노 (More Help) plants and insects. Paleobiology is the study of these creatures in their natural environment is a superior method of study over modern observational or experimental methods for exploring evolutionary phenomena. Paleobiology focuses on not only the process 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 Web site is divided into a variety of paths to learning evolution that include "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence that supports the theory of evolution. The course also focuses on common misconceptions about evolution as well as the evolution of thought.

Each of the other sections of the Evolution site is equally created, with resources that support a variety of curriculum levels and pedagogical styles. The site has a range of multimedia and interactive resources which include animations, video clips and virtual laboratories as well as general textual content. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation on the Web site.

The page "Coral Reef Connections", for example, provides an overview of the coral's relationships and their interactions with other organisms and then zooms in to one clam, which can 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 interactive pages on the website, provide an excellent introduction to a broad variety of topics in evolutionary biology. The material includes a discussion on the importance of natural selection and the concept of phylogenetics which is a crucial tool to understand evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach evolution across all disciplines of life science.

One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that provides depth and breadth in its educational resources. The site has a variety of interactive learning modules. It also has a nested "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely linked to the field of research science. An animation that introduces students to the concept of genetics links to a page that highlights John Endler's artificial-selection experiments with Guppies living in ponds native to Trinidad.

The Evolution Library on this website is a vast multimedia library of resources that are associated with evolution. The content is organized into the form of curriculum-based pathways that are in line with the learning objectives set out in the biology standards. It includes seven short videos designed for classroom use. They can be streamed or purchased as DVDs.

Evolutionary biology is still a field of study that poses many important questions, including what triggers evolution and the speed at which it occurs. This is especially relevant to human evolution, 에볼루션 바카라 사이트 where it has been difficult to reconcile the idea that the physical traits of humans were derived from apes and religious beliefs that hold that humanity is unique among living things and 에볼루션카지노 holds a an exclusive place in the creation. It is soul.

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

While many scientific fields of study conflict with literal interpretations in religious texts, evolution biology has been a subject of intense debate and 무료에볼루션 resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the notions of evolution, other religions have not.
