Evolution Site - Teaching About Evolution

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

This site, which is a companion to the PBS series - provides teachers with materials which support evolution education and avoid the kinds of misconceptions that hinder it. It's laid out in the "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to effectively teach evolution. Non-scientists often misunderstand the subject, and some scientists even employ a definition that confuses it. This is especially relevant when discussing the nature of the words themselves.

As such, it is important to define terms used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful way. The site is both an accompanying site for the 2001 series, but it is also a resource on its own. The material is presented in a structured manner that makes it easier to navigate and comprehend.

The site defines terms such as common ancestor, the gradual process, and adaptation. These terms help frame the nature and relationship of evolution to other concepts in science. The website provides a summary of the ways the concept of evolution has been examined. This information will help to dispel the myths created by creationists.

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

Adaptation is the tendency of heritable traits to be more suited to the environment. This is a result of natural selection, which occurs when organisms that have better-adapted traits are more likely survive and reproduce than those with less adaptable traits.

Common ancestor (also known as common ancestor): The most recent ancestral ancestor shared by two or more species. By studying the DNA of these species, it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular that holds the information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution: 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 에볼루션바카라사이트 host and parasite.

Origins

Species (groups that can interbreed) develop through a series of natural changes in their offspring's traits. These changes can be caused by numerous factors, like natural selection, 에볼루션 룰렛 gene drift and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food resources and habitat, can slow or accelerate the process.

The Evolution site traces through time the evolution of various animal and 에볼루션 바카라 체험 plant groups and focuses on major changes in each group's history. It also examines the evolutionary history of humans and humans, a subject that is crucial for students to know.

Darwin's Origin was written in 1859, when only a few antediluvian fossils of human beings had been discovered. The famous skullcap, with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. Although the skullcap was not published until 1858, just a year before the first edition of the Origin was published, it is extremely unlikely that Darwin had seen or 에볼루션 룰렛 heard of it.

While the site is focused on biology, it contains a wealth of information about geology as well as paleontology. The most impressive features of the Web site are a set of timelines that illustrate how climatic and geological conditions have changed over time, and an interactive map of the geographical distribution of some fossil groups that are featured on the site.

While the site is a companion piece to a PBS television show however, it can stand on its own as a valuable resource for teachers and students. The site is well-organized, and provides easy links to the introductory material of Understanding Evolution (developed under the National Science Foundation's support) and the more specific features of the museum's website. These hyperlinks make it easier to transition 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 plants, animals and insects. Paleobiology is the study of these creatures within their natural environment and has many advantages over the modern observational and research methods for analyzing evolutionary phenomena. In addition to exploring processes and events that occur frequently or over a long period of time, paleobiology is able to examine the diversity of species of organisms and their distribution throughout the geological time.

The Web site is divided into various paths to learning evolution that include "Evolution 101," which takes the user on a linear path through the science of nature and the evidence that supports the theory of evolution. The path also explores misconceptions about evolution and also the history of evolutionary thinking.

Each of the main sections of the Evolution website is equally well-developed, with materials that support a variety levels of curriculum and teaching methods. In addition to general textual content, the site features an array of multimedia and interactive resources including videos, animations and virtual labs. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the vast web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" provides a comprehensive overview of the coral's relationships and interactions with other organisms and is enlarged to show a single clam, which is able to communicate with its neighbours and respond to changes in the conditions of the water at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages gives a good introduction to many topics in evolutionary biology. The content also includes an explanation of the role of natural selection and the concept of phylogenetic analysis, which is an important method to understand evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that connects all branches of biology. A rich collection supports teaching evolution across the life science disciplines.

One resource, 에볼루션 룰렛 which is the companion to PBS's television series Understanding Evolution is an excellent example of an Web site that provides the depth and the breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also has an "bread crumb structure" that allows students to move away from the cartoon style of Understanding Evolution and 에볼루션 사이트 [Juniorshop.Ru] onto elements of this vast website that are closely connected to the worlds of research science. For instance an animation that introduces the notion of genetic inheritance leads to a page highlighting 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 materials that deal with evolution. The content is organized according to curricula-based pathways that correspond to the learning goals established in the biology standards. It contains seven videos that are designed for use in classrooms. They are available to stream or purchase as DVDs.

Many important questions remain at the core of evolutionary biology, such as what triggers evolution and how fast it happens. This is especially true for the evolution of humans, where it was difficult to reconcile religious beliefs that humans have a distinct position in the universe and a soul with the notion that our physical traits were derived from the apes.

There are a myriad of other ways evolution can take place and natural selection being the most well-known theory. Scientists also study different types such as mutation, genetic drift and sexual selection.

Although many scientific fields of study are in conflict with literal interpretations found in religious texts, the concept of evolution biology has been the subject of intense debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, others have not.
