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 aren't believers in evolution.

This rich website - companion to the PBS series - provides teachers with materials which support evolution education and avoid the kinds of misinformation that can undermine it. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and difficult subject matter to teach well. Non-scientists often misunderstand the subject and some scientists use a definition which confuses it. This is particularly relevant when discussing the nature of the words themselves.

It is therefore important to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful manner. The site is both a companion for the 2001 series, and also a resource of its own. The material is presented in a nested manner that aids navigation and orientation.

The site defines terms such as common ancestor, the gradual process and adaptation. These terms help frame the nature of evolution and its relationship to evolution to other concepts in science. The site then offers an overview of how the concept of evolution has been tested and validated. This information can be used to dispel myths that have been created by the creationists.

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

Adaptation: The tendency for hereditary traits to become more adaptable to a specific environment. This is a result of natural selection. Organisms with better-adapted traits are more likely than those with less adapted traits to reproduce and survive.

Common ancestor (also known as common ancestor) is the most recent ancestor that is shared by two or 바카라 에볼루션 (Xintangtc.Com) more species. By analyzing the DNA from these species it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular that contains the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are the source of new genetic information in cells.

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

Origins

Species (groups which can interbreed) develop through a series of natural changes in the traits of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, like climate changes or competition for food resources and habitat, can slow or accelerate the process.

The Evolution site tracks the development of a number of different animal and plant groups through time, focusing on the major changes that took place in the history of each group. It also examines the evolution of humans, which is a topic that is of particular interest for students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. Although the skullcap was not published until 1858, one year after the first edition of the Origin appeared, it is very unlikely that Darwin had seen or 무료에볼루션 바카라 무료 (Yates-albertsen.Thoughtlanes.net) heard of it.

The site is mostly an online biology resource however, it also has a lot of information on geology and paleontology. The most impressive features of the website are a timeline of events that illustrate how climatic and geological conditions have changed over time, as well as an interactive map of the distribution of some of the fossil groups featured on the site.

Although the site is a companion to a PBS television series however, it can stand on its own as an excellent resource for teachers and students. The site is well-organized, and provides easy links to the introductory information of Understanding Evolution (developed under the National Science Foundation's support) and the more specific features on the museum's website. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated realms of research science. There are also links to John Endler's experiments with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has resulted in a variety of plants, animals, and insects. Paleobiology is the study of these creatures in their geological context and has numerous advantages over the current observational and experimental methods for analyzing evolutionary processes. Paleobiology is able to study not just the processes and events that take place frequently or over time, but also the distribution and frequency of different groups of animals in space throughout the geological time.

The website 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 that supports the theory of evolution. The course also focuses on misconceptions about evolution, and also the history of evolutionary thought.

Each of the main sections on the Evolution website is equally well-designed, with materials that can be used to support a variety of educational levels and teaching styles. The site offers a wide array of multimedia and interactive resources that include animations, video clips and virtual labs, in addition to its general textual content. The content is presented in a nested bread crumb-like fashion that helps with navigation and orientation on the Web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of the relationships between corals and 에볼루션카지노 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, as well as the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a wide range of topics in evolutionary biology. The information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is an important method to understand evolutionary changes.

Evolutionary Theory

For biology students the concept of evolution is a major thread that connects all the branches of the field. A vast collection of resources helps teachers teach about evolution across all life sciences.

One resource, the companion to PBS's television series Understanding Evolution is an excellent example of a Web page that offers both depth as well as broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also has an encased "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this massive website that are closer to the field of research science. For instance, an animation introducing the idea of genetic inheritance connects to a page highlighting John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related to evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning goals set forth in biology standards. It contains seven short videos specifically designed for use in classrooms. They can be streamed or purchased as DVDs.

A number of important questions remain at the core of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is especially relevant to human evolution, where it has been difficult to reconcile that the innate physical characteristics of humans evolved from apes, and the religious beliefs that hold that humanity is unique among living things and has an enviable place in creation, with soul.

In addition, there are a number of ways that evolution can occur, with natural selection being the most widely accepted theory. Scientists also study other kinds like mutation, 에볼루션 게이밍 genetic drift, and sexual selection.

While many fields of scientific inquiry are in conflict with literal interpretations of religious texts evolutionary biology has been the subject of controversial debate and 에볼루션 게이밍 resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the ideas of evolution, other religions haven't.
