Evolution Site - Teaching About Evolution

Despite the best efforts by biology educators, misconceptions persist about the evolution. Pop science nonsense has led people to think that biologists don't believe in evolution.

This rich website - companion to the PBS series - provides teachers with materials that promote evolution education and avoids the kinds of misconceptions that hinder it. It's laid out in a "bread crumb" format to aid in navigation and orientation.

Definitions

It's not easy to properly teach evolution. Many non-scientists are unable to grasp the concept and 에볼루션 바카라 some scientists use a definition which confuses it. This is particularly 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 provides this in an easy and helpful manner. The site is a companion site to the series that first aired in 2001, but also functions as an independent resource. The material is presented in a nested fashion which aids navigation and orientation.

The site defines terms such as common ancestor, gradual process, and adaptation. These terms help frame the nature and significance of evolution to other concepts in science. The site gives a comprehensive overview of the way that evolution has been tested. This information can be used to dispel the myths that have been engendered by creationists.

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

Adaptation: The tendency of hereditary traits to become more adaptable to a specific environment. This is the result of natural selection, which occurs when organisms that have more adaptable traits are more likely survive and reproduce than those with less adaptable characteristics.

Common ancestor: The most recent common ancestor of two or more different species. The common ancestor can be identified by analyzing the DNA of those species.

Deoxyribonucleic Acid: A large 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 source of new genetic information in cells.

Coevolution is a relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution are the interactions between predator and prey or host and parasite.

Origins

Species (groups of individuals that can interbreed) develop through natural changes in the characteristics of their offspring. Changes can be caused by many factors, such as natural selection, gene drift and 에볼루션 게이밍 mixing of the gene pool. The evolution of a new species could take thousands of years, and the process could be slowed or increased by environmental conditions such as climate change or the competition for food or habitat.

The Evolution site tracks the evolution of various animal and plant groups through time with a focus on the key shifts that occurred throughout each group's history. It also examines the evolutionary origin of humans which is crucial for 에볼루션 students to know.

Darwin's Origin was published in 1859, 에볼루션 무료 바카라 when only a handful of antediluvian fossils of humans had been found. The famous skullcap, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as 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 heard or seen of it.

While the site is focused on biology, it includes a good deal of information about geology and paleontology. The website has numerous aspects that are quite impressive, including an overview of the way that climate and geological conditions have changed over time. It also has an interactive map that shows the location of fossil groups.

The site is a companion for the PBS TV series but it can also be used as an educational resource by teachers and students. The site is well-organized and offers clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features of the museum's website. These links 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 illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology, the study of these creatures in their natural environment offers many advantages over modern observational or 에볼루션 게이밍 experimental methods for studying evolutionary processes. In addition to studying processes and events that occur regularly or over a lengthy period of time, paleobiology can be used to analyze the diversity of kinds of organisms as well as their distribution throughout geological time.

The website is divided into various ways to learn about evolution that include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence supporting the theory of evolution. The path also examines myths about evolution, and the background of evolutionary thinking.

Each of the other sections of the Evolution site is similarly developed, with materials that can support a variety of curriculum levels and pedagogical styles. In addition to the general textual content, the site also has an extensive selection of interactive and multimedia resources like video clips, animations, and virtual laboratories. The breadcrumb-like organization of the content helps with navigation and orientation on the vast Web site.

The page "Coral Reef Connections" For instance, it gives a brief overview of coral relationships and interactions with other organisms, and then is enlarged to show one clam that is able communicate with its neighbors and react to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary, multimedia, and 에볼루션 게이밍 interactive pages on the site, offer an excellent introduction to a broad range of topics in evolutionary biology. The content includes a discussion on the importance of natural selection and the concept of phylogenetics analysis which is a crucial tool for understanding evolutionary change.

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A rich collection of resources helps teachers teach about evolution across the life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that provides depth and a variety of educational resources. The site offers a 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 huge site that are closer to the field of research science. For example, an animation introducing the notion of genetic inheritance leads to a page that highlights John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

Another helpful resource is the Evolution Library on this web website, which includes an extensive collection of multimedia assets connected to evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives set out in the biology standards. It includes seven short videos that are designed for classroom use. These can be viewed online or purchased as DVDs.

Evolutionary biology is still an area of study that poses many important questions to answer, such as the causes of evolution and how quickly it happens. This is particularly true for humans' evolution, where it was difficult to reconcile religious beliefs that held that humanity has a special place in creation and a soul, with the notion that our physical traits originated from Apes.

There are a myriad of other ways in which evolution can take place and natural selection being the most widely accepted theory. Scientists also study other kinds like mutation, genetic drift, and sexual selection.

While many fields of scientific inquiry have a conflict with literal interpretations of the Bible Evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the ideas of evolution, other religions haven't.
