Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions persist 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 offers teachers with resources that promote evolution education and help avoid the kinds of myths that undermine it. It's organized in the "bread crumb" format to make navigation and orientation easier.

Definitions

It's difficult to effectively teach evolution. It is often misunderstood by non-scientists and even some scientists use definitions that confuse the issue. This is especially relevant when discussing the definition of the words.

It is therefore important to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and 에볼루션 바카라 체험게이밍 (click here now) efficient way. The website is a companion to the show that premiered in 2001, but also functions as an independent resource. The content is organized in a manner that makes it easier to navigate and comprehend.

The site defines terms such as common ancestor (or common ancestor), gradual process and adaptation. These terms help frame the nature and relationship of evolution to other concepts in science. The site gives a comprehensive overview of the ways that evolution has been examined. This information can help dispel the myths that are created by the creationists.

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

Adaptation: The tendency for hereditary traits to become more adaptable to a specific environment. This is due to natural selection. It occurs when organisms that have better adapted traits are more likely survive and reproduce than those with less adapted characteristics.

Common ancestor (also known as common ancestor) is the most recent ancestor that is shared by two or more species. The common ancestor can be identified by studying the DNA of these species.

Deoxyribonucleic Acid: A large biological molecular containing the information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together to form long chains, also known as chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is a relation between two species where evolutionary changes of one species are influenced evolutionary changes of the other. Coevolution can be seen in the interactions between predator 에볼루션 바카라 and prey, or 에볼루션 바카라 무료 parasite and hosts.

Origins

Species (groups of individuals who can interbreed) develop through natural changes in the traits of their offspring. These changes are caused by a variety of causes that include natural selection, genetic drift, and gene pool mixing. The evolution of new species could take thousands of years. Environmental conditions, such as climate changes or competition for food or habitat can slow or speed up the process.

The Evolution site follows the evolution of different animal and plant groups with a focus on major changes in each group's history. It also examines the evolutionary origin of humans, a topic that is particularly important for 에볼루션 바카라 무료 students to understand.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been discovered. The famous skullcap, with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one year before the first edition of the Origin was published, it is highly unlikely that Darwin had seen or heard of it.

The site is mostly one of biology however, it also has many details on paleontology and geology. One of the most appealing features of the website are a timeline of events that illustrate how climatic and geological conditions have changed over time, and a map of the geographical distribution of some of the fossil groups featured on the site.

The site is a companion to the PBS television series, but it can be used as a source 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 funding) and the more specific features of the museum's website. These hyperlinks facilitate the move from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly 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, the study of these creatures within their geological environment, has many advantages over modern observational or experimental methods for studying evolutionary processes. In addition to studying processes and events that take place regularly or over a lengthy period of time, paleobiology allows to analyze the relative abundance of various kinds of organisms as well as their distribution across the course of geological time.

The website is divided into various paths to learning evolution which include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence supporting the theory of evolution. The course also focuses on misconceptions about evolution, and the background of evolutionary thinking.

Each of the other main sections of the Evolution site is equally well constructed, with materials that support a variety of educational levels and pedagogical styles. The site offers a wide array of multimedia and interactive resources which include video clips, animations and virtual laboratories in addition to general textual content. The content is organized in a nested, bread crumb-like fashion that helps with navigation and 에볼루션 바카라 orientation within the vast Web site.

For example the page "Coral Reef Connections" gives a brief overview of coral relationships and 에볼루션 바카라 무료 their interactions with other organisms. Then, it zooms in on a single clam that can communicate with its neighbors and respond to changes in water conditions that take place at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to the many areas of evolutionary biology. The information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is a crucial tool in understanding evolutionary changes.

Evolutionary Theory

For biology students, evolution is a key thread that connects all branches of the field. A vast collection of books helps in teaching evolution across all disciplines of life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that provides the depth and breadth of 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 that is used in Understanding Evolution and onto elements on this large website more closely connected to the fields of research science. For example an animation that explains the idea of genetic inheritance connects to a page that focuses on John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

The Evolution Library on this website is a vast multimedia library of assets related to evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives set out in biology standards. It includes seven short videos designed specifically for use in classrooms, and can be streamed at no cost or purchased on DVD.

Many important questions remain at the core of evolutionary biology, including what causes evolution to occur and how fast it occurs. This is especially applicable to human evolution which has made it difficult to reconcile that the physical characteristics of humans derived from apes with religions that believe that humans are unique in the universe and has an exclusive place in the creation with a soul.

Additionally there are a myriad of ways in which evolution could occur and natural selection is the most popular theory. However, scientists also study other kinds of evolution, such as mutation, genetic drift and sexual selection, among other things.

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 opposition from religious fundamentalists. Certain religions have reconciled their beliefs to evolution but others haven't.
