Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution remain. Pop science fiction has led a lot of people to think that biologists don't believe in evolution.

This rich Web site, a companion to the PBS program offers teachers resources that promote evolution education while avoiding the types of misconceptions which hinder it. It's organized in the "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and difficult subject matter to teach well. Many non-scientists are unable to grasp the concept and some scientists use a definition that confuses it. This is especially relevant when it comes to the meaning of the words themselves.

It is therefore essential to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient manner. The website is a companion to the show that premiered in 2001, but is also an independent resource. The information 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 frame the nature of evolution and its relationship to evolution to other scientific concepts. The website provides a summary of the manner in which evolution has been examined. This information can help dispel the myths created by creationists.

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

Adaptation is the process of changing heritable traits to become better suited to an environment. This is the result of natural selection. Organisms with better-adapted traits are more likely than those with less-adapted traits to reproduce and survive.

Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified through analyzing the DNA of these species.

Deoxyribonucleic Acid: A large biological molecular that contains the information required for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution is the relationship between two species, where the evolution of one species are influenced by evolutionary changes of the other. Examples of coevolution are the interactions between predator and prey, or host and 에볼루션코리아 parasite.

Origins

Species (groups of individuals that can interbreed) develop through natural changes in the characteristics of their offspring. These changes can be caused by many factors, such as natural selection, gene drift, and mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, like changes in the climate or competition for food or 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 in each group's history. It also focuses on human evolution as a subject that is particularly important for students.

Darwin's Origin was written in 1859, at a time when only a handful of antediluvian fossils of human beings had been 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 before the first edition of the Origin appeared, it is very unlikely that Darwin had seen or heard of it.

While the site is focused on biology, it also contains a wealth of information on geology and paleontology. The website has a number of features that are especially impressive, including an overview of the way that climate and geological conditions have changed over the course of time. It also includes a map showing the distribution of fossil groups.

The site is a companion to a PBS television series, but it could be used as a resource for teachers and 바카라 에볼루션 블랙잭 (the full details) students. The site is well-organized, and provides clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's support) and the more specialized 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 worlds of research science. In particular there are links to John Endler's experiments with Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of plants, animals, and insects. Paleobiology is the study of these creatures within their geographical context and offers a number of advantages over the current observational and experimental methods of examining evolutionary processes. In addition to examining processes and events that take place regularly or over a lengthy period of time, paleobiology is able to examine the diversity of species of organisms and their distribution across the course of geological time.

The website is divided into various paths to learning evolution that include "Evolution 101," which takes the viewer on a liner path through the nature of science and 에볼루션 바카라사이트 the evidence supporting the theory of evolution. The path also explores misconceptions regarding evolution, and the background of evolutionary thought.

Each of the main sections of the Evolution website is equally well-developed, 에볼루션 블랙잭 with materials that are suited to a variety of levels of curriculum and teaching methods. In addition to the standard textual content, the site also has an array of multimedia and interactive resources, such as videos, animations and virtual laboratories. The breadcrumb-like organization of the content helps with navigation and orientation on the large Web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships, their interaction with other organisms and zooms in to one clam, which can communicate with its neighbours and respond to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to a wide variety of 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 tool in understanding evolutionary change.

Evolutionary Theory

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

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that offers both depth as well as breadth in terms of its educational resources. The site features a wide range of interactive learning modules. It also features an encased "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this massive website that are closer to the field of research science. An animation that introduces the concept of genetics links to a page about John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.

Another resource that is worth mentioning is the Evolution Library on this site, which has an extensive multimedia library of items connected to evolution. The content is organized according to curricula-based pathways that correspond to the learning goals established in biology standards. It includes seven short videos specifically designed for classroom use, which can be streamed at no cost or purchased on DVD.

Many important questions remain at the core of evolutionary biology, such as what triggers evolution and the speed at which it occurs. This is particularly relevant to human evolution, 에볼루션 코리아 which has made it difficult to reconcile the idea that the innate physical characteristics of humans were derived from apes and 에볼루션 카지노 religions that believe that humanity is unique among living things and has a special place in creation with a soul.

In addition there are a myriad of ways in which evolution could be triggered and natural selection is the most widely accepted theory. Scientists also study other types such as genetic drift, and sexual selection.

While many fields of scientific study conflict with literal interpretations found in religious texts, the concept of evolution biology has been a source of intense debate and resistance from religious fundamentalists. Certain religions have embraced their beliefs with evolutionary biology, while others haven't.
