Evolution Site - Teaching About Evolution

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

This site, which is a complement to the PBS program offers teachers resources that support the evolution of education, while avoiding the kinds of misconceptions which undermine it. It's laid out in a nested "bread crumb" format to make it easy for navigation and orientation.

Definitions

Evolution is a complicated and difficult subject to teach well. It is often misunderstood by non-scientists and even scientists have been guilty of using definitions that confuse the issue. This is especially true when it comes to discussions about the definition of the word itself.

It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and 에볼루션 바카라 무료 useful manner. The site is a companion site to the show which first aired in 2001, but can also function as an independent resource. The information is presented in a structured way that makes it easy to navigate and comprehend.

The site defines terms like common ancestor, gradual process and adaptation. These terms help frame the nature of evolution and its relation to other scientific concepts. The website then provides an overview of how the concept of evolution has been tested and validated. This information can help dispel myths created by creationists.

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

Adaptation: The tendency for hereditary traits to become more suited to a particular environment. This is due to natural selection, which happens when organisms that have better adapted traits are more likely survive and reproduce than those with less adapted traits.

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

Deoxyribonucleic acid: A huge biological molecule that contains information needed for cell replication. The information is contained in nucleotides arranged in sequences that are strung together into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution is a relationship between two species where evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution can be seen in the interaction of predator and prey, or parasite and hosts.

Origins

Species (groups of individuals that can interbreed) evolve through an array of natural changes in the characteristics of their offspring. These changes are caused by a variety of factors such as natural selection, genetic drift, and mixing of genes. The evolution of new species can take thousands of years. Environmental circumstances, such as changes in the climate or competition for food resources and habitat can impede or accelerate the process.

The Evolution site tracks through time the evolution of various species of plants and animals, focusing on major transitions in each group's history. It also examines the evolutionary origin of humans which is especially important for students to know.

Darwin's Origin was written in 1859, at a time when only a few antediluvian fossils of human beings had been discovered. One of them was the infamous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany that is now thought 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 is highly unlikely that Darwin had heard or seen of it.

The site is mostly an online biology resource however, it also has lots of information about geology and paleontology. The website has a number of features that are particularly impressive, such as a timeline of how climate and geological conditions have changed over the course of time. It also features an interactive map that shows the location of fossil groups.

While the site is a companion piece to the PBS television series but it also stands on its own as an excellent resource for teachers and students. The site is well-organized, and provides clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's support) and 에볼루션 슬롯게임, evolution47242.Wizzardsblog.Com, the more specialized features of the museum's website. These hyperlinks make it easier to move 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. They illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has led to a wide variety of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment and has many advantages over modern observational and experimental methods in its exploration of evolutionary processes. Paleobiology is able to study not only the process and events that take place regularly or over time but also the relative abundance and distribution of different groups of animals in space over the course of geological time.

The website is divided into different options to study the subject of evolution. One of these paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The path also explores common misconceptions about evolution and the evolution theory's history.

Each of the other sections of the Evolution site is equally developed, with materials that can support a variety of different pedagogical levels and curriculum levels. The site has a range of interactive and multimedia resources which include videos, animations, and virtual laboratories, in addition to its general textual content. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation on the Web site.

The page "Coral Reef Connections", for example, provides a comprehensive overview of the coral's relationships, their interaction with other organisms and is enlarged to show a single clam, which can communicate with its neighbours and respond to changes in the conditions of the water that occur at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages gives a good introduction to the many areas of evolutionary biology. The information also includes 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 change.

Evolutionary Theory

For biology students the concept of evolution is a major thread that connects all the branches of the field. A rich collection supports teaching evolution across all life science disciplines.

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of an Web site that provides depth as well as breadth in terms of its educational resources. The site has a wide array of interactive learning modules. It also features a "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 linked to the worlds of research science. An animation that introduces the concept of genetics is linked to a page about John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.

Another useful resource is the Evolution Library on this site, which has an extensive multimedia library of items that are related to evolution. The content is organized according to curricula-based paths that correspond to the learning objectives set out in the standards for biology. It contains seven videos designed specifically for classroom use, which can be streamed for no cost or purchased on DVD.

Evolutionary biology is a field of study with a lot of important questions, such as the causes of evolution and the speed at which it takes place. This is especially true for humans' evolution where it was a challenge to reconcile religious beliefs that humans have a distinct position in the universe and a soul, with the idea that innate physical traits were derived from Apes.

Additionally there are a myriad of ways that evolution could be triggered and natural selection is the most popular theory. Scientists also study other kinds like mutation, genetic drift and sexual selection.

Although many scientific fields of study have a conflict with literal interpretations in religious texts, the concept of evolution biology has been a source of intense controversy and 에볼루션 사이트 블랙잭 (talks about it) opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the theories of evolution, other religions have not.
