Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution remain. Pop science nonsense has led people to believe that biologists aren't believers in evolution.

This rich Web site, which is a complement to the PBS program, provides teachers with materials that support the evolution of education while avoiding the types of misconceptions which make it difficult to understand. It's laid out in the "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to teach evolution well. It is often misunderstood by non-scientists, and even some scientists are guilty of using an interpretation that is confusing the issue. This is especially relevant when discussing the definition of the words.

Therefore, it is essential to define terms that are used in evolutionary biology. Understanding Evolution's website does this in a simple and efficient way. It is a companion for the 2001 series, 무료에볼루션 but also a resource of its own. The information is organized in a way that makes it easy 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 concepts in science. The site gives a comprehensive overview of the manner the concept of evolution has been examined. This information can help dispel the myths created by creationists.

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

Adaptation is the process of changing heritable traits to become better suited to an environment. This is a result of natural selection, which happens when organisms with better adapted traits are more likely survive and reproduce than those with less adapted traits.

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

Deoxyribonucleic acid: A massive biological molecule that holds the information necessary 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 within cells.

Coevolution is a relation between two species in which the evolution of one species are influenced by evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey or host and parasite.

Origins

Species (groups of individuals that can interbreed) change through an array of natural changes in the traits of their offspring. The changes can be triggered by a variety of factors, including natural selection, genetic drift and mixing of genes. The development of a new species could take thousands of years and the process could be slowed down or speeded up due to environmental conditions, such as climate change or competition for food or habitat.

The Evolution site traces the emergence of a variety of species of plants and animals over time, focusing on the major changes that took place in the evolution of each group's history. It also focuses on human evolution as a subject of particular importance for students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. Among them was the famous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap when it was published in 1858, which was a year following the initial edition of The Origin. Origin.

While the site is focused on biology, it includes a good deal of information on geology and paleontology. The most impressive features of the website are a set of timelines that show how geological and climatic conditions changed over time, and 에볼루션 코리아 an interactive map of the distribution of a few of the fossil groups featured on the site.

The site is a companion for the PBS TV series but it could also be used as an educational resource for teachers and students. The site is very well-organized and has clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum's web site. 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, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures within their geographical context and offers numerous advantages over modern observational and experimental methods for analyzing evolutionary phenomena. In addition to exploring processes and events that take place frequently or over a long period of time, paleobiology is able to examine the relative abundance of various species of organisms and their distribution across the geological time.

The Web site is divided into various paths to learning evolution, including "Evolution 101," which takes the viewer on a liner path through the science of nature and the evidence supporting the theory of evolution. The course also focuses on common misconceptions about evolution and the history of evolutionary thought.

Each of the other sections of the Evolution site is equally well created, with resources that support a variety of different pedagogical levels and curriculum levels. The site includes a variety of multimedia and interactive resources which include animations, video clips and virtual laboratories as well as general textual content. The content is organized in a nested, bread crumb-like fashion that helps with navigation and orientation within the vast web site.

The page "Coral Reef Connections", for example, 에볼루션 바카라사이트 provides a comprehensive overview of the relationships between corals and their interactions with other organisms and 에볼루션사이트 then is enlarged to show a single clam, which can communicate with its neighbors and respond to changes in conditions of the water at the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages gives a good introduction to the many areas of evolutionary biology. The information also includes an overview of the importance of natural selection and the concept of phylogenetic analysis, which is an important tool in understanding evolutionary change.

Evolutionary Theory

For biology students, evolution is a key thread that weaves together all the branches of the field. A rich collection supports teaching evolution across the disciplines of life science.

One resource, which is a companion to the PBS television series Understanding Evolution, is an outstanding example of a Web site that offers both depth and breadth in its educational resources. The site offers a variety of interactive learning modules. It also has an "bread crumb structure" that helps students move away from the cartoon-like style that is used in Understanding Evolution and onto elements on this site that are more closely connected to the worlds of research science. For instance an animation that introduces the notion of genetic inheritance leads to a page that highlights John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.

Another resource that is worth mentioning is the Evolution Library on this web site, which contains an extensive multimedia library of items connected to evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives set out in biology standards. It includes seven short videos that are intended for use in the classroom. They can be streamed or purchased as DVDs.

Evolutionary biology remains a field of study with a lot of important questions to answer, such as what causes evolution and the speed at which it occurs. This is particularly true in the case of human evolution where it was a challenge to reconcile religious beliefs that held that humans have a distinct place in creation and a soul, with the notion that our physical traits originated from Apes.

There are a variety of other ways evolution could occur, with natural selection as the most popular theory. However scientists also study other kinds of evolution like mutation, genetic drift and sexual selection, among others.

While many scientific fields of inquiry conflict with literal interpretations of religious texts Evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Some religions have reconciled their beliefs with evolutionary biology, but others haven't.
