Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution persist. People who have absorbed pop science nonsense often assume that biologists are saying they don't believe in evolution.

This site, which is a companion to the PBS series offers teachers with resources that promote evolution education and avoid the kinds of misconceptions that undermine it. It's laid out in the "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complex and difficult subject matter to teach well. People who are not scientists often have a difficult time understanding the subject and some scientists use a definition which confuses it. This is particularly true when discussing the nature of the words themselves.

It is therefore crucial to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient way. The site is a companion site to the show that premiered in 2001, but is also an independent resource. The information is presented in a structured manner that makes it simpler to navigate and understand.

The site defines terms like common ancestor and gradual process. These terms help to define 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 confirmed. This information can help dispel the myths created by creationists.

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

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

Common ancestor: 에볼루션코리아 The latest common ancestor of two or more distinct species. The common ancestor can be identified by analyzing the DNA of those species.

Deoxyribonucleic acid: A huge biological molecule that contains information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains called chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is the relationship between two species where evolution of one species influence evolutionary changes of the other. Examples of coevolution include the interaction between predator and prey, or host and parasite.

Origins

Species (groups that can interbreed) develop by a series of natural variations in the traits of their offspring. The changes can be caused by a variety of factors, including natural selection, genetic drift and mixing of gene pools. The development of a new species could take thousands of years, and the process may be slowed or increased by environmental factors like climate change or the competition for food or habitat.

The Evolution site tracks through time the emergence of various species of plants and animals and focuses on major changes in each group's past. It also explores the evolutionary origin of humans, a topic that is crucial for students to understand.

Darwin's Origin was written in 1859, when just a few antediluvian fossils of human beings had been discovered. The famous skullcap, along with the bones that accompanied it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is unlikely that Darwin was aware of the skullcap, which was published in 1858, which was a year after the first edition of The Origin. Origin.

While the site focuses on biology, it also includes a good deal of information about geology and paleontology. The most impressive features on the site are a series of timelines that show the way in which climatic and geological conditions have changed over time as well as a map of the distribution of a few of the fossil groups featured on the site.

Although the site is a companion piece to the PBS television show but it also stands on its own as an excellent resource for teachers and students. The site is extremely well-organized and 에볼루션 바카라 무료 offers clear links between the introductory content 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 engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are hyperlinks to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures within their geological context is a superior method of study over the current observational or experimental methods of studying evolutionary phenomena. In addition to studying processes and events that occur regularly or over a long period of time, paleobiology allows to analyze the relative abundance of different species of organisms and their distribution in space over the course of geological time.

The Web site is divided into several optional pathways to understanding evolution, including "Evolution 101," which takes the viewer on a line through the science of nature and the evidence that supports the theory of evolution. The path also explores misconceptions about evolution and also the history of evolutionary thinking.

Each of the other sections of the Evolution site is similarly developed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. In addition to the general textual content, the site offers a wide range of interactive and multimedia resources like videos, animations and virtual labs. 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 에볼루션 사이트 example, provides an overview of the relationships between corals, their interaction with other organisms and zooms in to one clam that is able communicate with its neighbours and respond to changes in conditions of the water at the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The content also includes an overview of the importance of natural selection and the concept of phylogenetics analysis as a key method for understanding the evolution of changes.

Evolutionary Theory

Evolution is a common thread that connects all branches of biology. A wide selection of resources helps teachers teach evolution across the life science disciplines.

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of a Web page that provides the depth and the broadness in terms of educational resources. The site features a wealth of interactive learning modules. It also features a nested "bread crumb" structure that helps students transition from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the field of research science. For example, an animation introducing the idea of genetic inheritance connects to a page that highlights John Endler's experiments in artificial selection with guppies from the native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of materials that deal with evolution. The content is organized according to curriculum-based pathways that correspond to the learning objectives outlined in the standards for 에볼루션 무료체험 biology. It includes seven short videos specifically designed for classroom use, which can be streamed for free or purchased on DVD.

Evolutionary biology is a field of study with a lot of important questions to answer, such as what causes 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 humanity has a special position in the universe and a soul, with the notion that human beings have innate physical traits evolved from apes.

There are a myriad of other ways evolution can take place, with natural selection as the most popular theory. However scientists also study different kinds of evolution, such as mutation, genetic drift and sexual selection, among others.

While many fields of scientific study conflict with literal interpretations found in religious texts, the concept of evolution biology has been the subject of intense debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, while others haven't.
