5 Evolution Site Lessons Learned From The Professionals

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution persist. People who have been exposed to pop science nonsense often assume that biologists claim they don't believe in evolution.

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

Definitions

It's not easy to effectively teach evolution. It is often misunderstood even by non-scientists, and even some scientists are guilty of using an interpretation that is confusing the issue. This is especially relevant to discussions on the definition of the word itself.

It is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient manner. The website is a companion to the show which first aired in 2001, but it can also function as an independent resource. The content is presented in a nested fashion that aids navigation and orientation.

The site defines terms like common ancestor, the gradual process and adaptation. These terms help frame the nature of evolution and 에볼루션 바카라 체험 its relation to other concepts in science. The site then offers an overview of how the concept of evolution has been vetted and verified. This information can be used to dispel myths that have been created by creationists.

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

Adaptation: The tendency of heritable traits to become better suitable to a particular setting. This is the result of natural selection, which happens when organisms that have better-adapted traits are more likely survive and reproduce than those with less adaptable characteristics.

Common ancestor (also called 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 massive biological molecular that holds the necessary information for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are the cause of new genetic information in cells.

Coevolution is a relation between two species where evolutionary changes of one species influence evolutionary changes of the other. Coevolution can be seen through the interaction between predator and prey, or parasite and hosts.

Origins

Species (groups of individuals that are able to interbreed) develop through natural changes in the characteristics of their offspring. The changes can be caused by a variety of factors that include natural selection, genetic drift, and mixing of genes. The evolution of new species can take thousands of years. Environmental conditions, like changes in the climate or competition for food and habitat, can slow or accelerate the process.

The Evolution site tracks through time the emergence of various animal and plant groups with a focus on major changes in each group's past. It also focuses on human evolution as a subject that is particularly important to students.

Darwin's Origin was published in 1859, 에볼루션 무료체험 when only a handful of antediluvian fossils of humans had been found. The famous skullcap, with the associated bones 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, one year before the first edition of the Origin was published, it's highly unlikely that Darwin had ever heard of it.

The site is primarily a biology site however it also includes many details on paleontology and geology. Among the best features of the Web site are a set of timelines which show the way in which climatic and geological conditions changed over time, and a map of the distribution of a few of the fossil groups featured on the site.

The site is a companion for a PBS television series, but it can also be used as an educational resource by 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 assistance) and the more specific features on the museum's website. These hyperlinks help users move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. Particularly there are links to John Endler's research with guppies that illustrate 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 modern observational and research methods of examining evolutionary processes. In addition to examining processes and events that occur frequently or over a long period of time, paleobiology is able to examine the relative abundance of different species of organisms and their distribution throughout geological time.

The site is divided into different routes that can be taken to learn about evolution. One of these paths, "Evolution 101," takes the viewer through the evolution of nature and the evidence of evolution. The path also reveals common misconceptions about evolution and the evolution of thought.

Each of the other sections of the Evolution site is equally developed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. The site offers a wide array of interactive and multimedia resources that include videos, animations, and virtual labs in addition to general textual content. The content is presented in a nested bread crumb style that facilitates navigation and orientation on the Web site.

For instance, the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms. It then concentrates on a specific clam that can communicate with its neighbours and respond to changes in the water conditions that occur at the level of the reef. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a broad range of topics in evolutionary biology. The material also provides an explanation of the role of natural selection as well as the concept of phylogenetic analysis, which is an important tool for understanding the evolution of changes.

Evolutionary Theory

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

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of a Web site that provides the depth and the broadness in terms of educational resources. The site offers a variety of interactive learning modules. It also has an encased "bread crumb" structure that allows students to move from the cartoon-like style of Understanding Evolution to elements on this large Web site more closely linked to the field of research science. For example an animation that introduces the notion of genetic inheritance leads to a page that focuses on John Endler's experiments with artificial selection with guppies in native ponds of Trinidad.

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

Evolutionary biology remains an area of study that has many important questions, such as what triggers evolution and how quickly it happens. This is especially true in the case of human evolution, where it was difficult to reconcile religious beliefs that held that humans have a distinct position in the universe and a soul with the notion that human beings have innate physical traits were derived from the apes.

Additionally there are a variety of ways in which evolution could be triggered and natural selection is the most popular theory. However scientists also study different kinds of evolution like mutation, genetic drift and sexual selection, among other things.

Many fields of inquiry are in conflict with literal interpretations of religious texts evolutionary biology has been the subject of intense controversy and 무료 에볼루션 블랙잭 (read article) resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, other religions aren't.
