Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, there are still misconceptions regarding evolution. People who have taken in the nonsense of pop science often believe that biologists are saying they don't believe in evolution.

1-5-890x664.jpgThis rich Web site, a companion to the PBS program that provides teachers with resources that support the evolution of education, while avoiding the kinds of misconceptions that make it difficult to understand. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

It's difficult to effectively teach evolution. Non-scientists often misunderstand the subject, and some scientists even use a definition which confuses it. This is particularly true when it comes to discussions on the definition of the word itself.

It is therefore crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful way. It is an accompaniment to the 2001 series, and it is also a resource on its own. The material is presented in a structured manner that makes it easier to navigate and understand.

The site defines terms such as common ancestor and gradual process. These terms help to define the nature and significance of evolution to other scientific concepts. The site also provides 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 consult a glossary that includes terms used in evolutionary biology. These terms include:

Adaptation is the tendency of heritable traits to become better suited to an environment. This is a result of natural selection. Organisms with more adaptable characteristics are more likely than those with less adaptable characteristics to survive and reproduce.

Common ancestor (also called common ancestor) The most recent ancestral ancestor shared by two or more species. The common ancestor can be identified by analyzing the DNA of these species.

Deoxyribonucleic acid: A large biological molecule that contains information needed for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the source of new genetic information within cells.

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

Origins

Species (groups of individuals who can interbreed) evolve through a series of natural changes in the characteristics of their offspring. The changes can be caused by a variety such as natural selection, genetic drift, and mixing of genes. The evolution of a new species could take thousands of years, and the process could be slowed down or accelerated by environmental conditions such as climate change or competition for food or habitat.

The Evolution site tracks the evolution of a number of different animal and plant groups through time and focuses on the most significant changes that took place in the history of each group. It also focuses on the human evolutionary roots, 에볼루션 바카라 사이트 a topic that is particularly important for students to know.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. One of them was the infamous 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. Although the skullcap was not published until 1858, one year before the first edition of the Origin was published, 에볼루션 it is highly unlikely that Darwin had heard or seen of it.

The site is mostly a biology site however, it also has a lot of information on geology and paleontology. The site offers a number of features that are particularly impressive, such as the timeline of the way that climate and geological conditions have changed over time. It also includes a map showing the distribution of fossil groups.

The site is a companion to the PBS television series, but it could be used as a resource by teachers and students. The site is extremely well-organized and 에볼루션 바카라 offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks make it easy 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 that illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of plants, animals and insects. Paleobiology, the study of these creatures in their geological context, has many advantages over the current observational or experimental methods for exploring evolutionary processes. In addition to examining processes and events that occur frequently or over a long period of time, paleobiology is able to analyze the relative abundance of various species of organisms and their distribution across the geological time.

The site is divided into several optional paths to learning evolution that include "Evolution 101," which takes the viewer on a liner path through the scientific process and the evidence that supports the theory of evolution. The path also reveals the most common misconceptions about evolution, as well as the evolution of thought.

Each of the other sections of the Evolution site is similarly developed, with materials that support a variety of educational levels and pedagogical styles. In addition to the general textual content, the site features an array of multimedia and interactive content including videos, animations, and virtual laboratories. The content is organized in a nested, bread crumb style that facilitates navigation and orientation within the vast Web site.

The page "Coral Reef Connections" For instance, it provides a comprehensive overview of the relationships between corals and their interactions with other organisms and then is enlarged to show one clam, which can 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 multimedia and interactive pages, provides an excellent introduction to many topics in evolutionary biology. The information also includes an explanation of the role of natural selection and the concept of phylogenetic analysis, which is a key method to understand evolutionary change.

Evolutionary Theory

Evolution is a common thread that runs through all branches of biology. A rich collection supports teaching evolution across the life science disciplines.

One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both depth and breadth in its educational resources. The site features a wealth of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this huge site that are more closely tied to the field of research science. For example, an animation introducing the notion of genetic inheritance leads to a page highlighting John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized according to curriculum-based paths that parallel the learning objectives outlined in the standards for biology. It contains seven videos designed specifically for use in the classroom, and can be streamed for no cost or purchased on DVD.

Evolutionary biology remains an area of study that has many important questions to answer, such as what triggers evolution and how fast it takes place. This is particularly applicable to human evolution which has made it difficult to reconcile the idea that the innate physical characteristics of humans evolved from apes, and the religions that believe that humanity is unique in the universe and has a special place in creation with soul.

There are a variety of other ways evolution could occur including natural selection, which is the most widely accepted theory. Scientists also study different types like mutation, genetic drift and sexual selection.

Depositphotos_274035516_XL-scaled.jpgWhile many scientific fields of study have a conflict with the literal interpretations of religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, 에볼루션 바카라 체험 while others haven't.
