Speak "Yes" To These 5 Evolution Site Tips

Evolution Site - Teaching About Evolution

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

This site, which is a complement to the PBS program, provides teachers with materials which support evolution education while avoiding the types of misconceptions which hinder it. It's organized in the "bread crumb" format to make navigation and orientation easier.

Definitions

It is difficult to effectively teach evolution. It is often misunderstood even by non-scientists, and even some scientists use definitions that confuse the issue. This is especially true when discussing the nature of the words themselves.

It is therefore essential to define the terms used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful manner. The site is a companion to the series that first aired in 2001, but it can also function as an independent resource. The material is presented in a nested fashion that assists in navigation and orientation.

The site defines terms such as common ancestor and gradual process. These terms help frame the nature of evolution and its relationship to other scientific concepts. The site provides an overview of the manner that evolution has been examined. This information can help dispel myths that are created by the creationists.

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

The process of adaptation is the tendency of heritable traits to be more suitable to their environment. This is the result of natural selection, which happens when organisms that are better adapted traits are more likely to survive and reproduce than those with less adaptable characteristics.

Common ancestor (also known as common ancestor) The most recent ancestor shared by two or more species. By studying the DNA of these species it is possible to identify the common ancestor.

Deoxyribonucleic Acid: A huge biological molecular that contains the necessary information for cell replication. The information is stored in nucleotide sequences which are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or the parasite and the host.

Origins

Species (groups of individuals who can interbreed) change through natural changes in the traits of their offspring. These changes are caused by a variety of causes that include natural selection, genetic drift and gene pool mixing. The evolution of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food and habitat, can slow or accelerate the process.

The Evolution site traces the emergence of a variety of groups of animals and plants over time, focusing on the major transitions that occurred in the history of each group. It also focuses on human evolution and is a subject of particular importance to students.

Darwin's Origin was published in 1859, when only a handful of antediluvian fossils of humans were discovered. The most famous among them was the skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, a year before the first edition of the Origin appeared, it is highly unlikely that Darwin had ever heard of it.

While the site is focused on biology, it also offers a lot of information about geology and paleontology. One of the most appealing features on the site are a series of timelines which show how geological and climatic conditions have changed over time as well as a map of the distribution of some fossil groups that are featured on the site.

Although the site is a companion to the PBS television show however, it can stand on its own as a great source for teachers and students. The site is extremely well-organized and has clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These hyperlinks facilitate the move from the cartoon-like style of the Understanding Evolution pages to the more sophisticated world of research science. There are links to John Endler's experiments with 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, the study of these creatures within their geological context, has many advantages over modern observational or experimental methods for exploring evolutionary processes. Paleobiology can examine not just the processes and events that happen regularly or over time, but also the relative abundance and distribution of different species of animals across geological time.

The Web site is divided into several optional paths to learning evolution, including "Evolution 101," which takes the viewer on a line through the science of nature and the evidence to support the theory of evolution. The course also focuses on the most common misconceptions about evolution, as well as the evolution of thought.

Each of the main sections of the Evolution website is equally well-designed, with materials that are suited to a variety of curriculum levels and teaching styles. In addition to the general textual content, the site also has an array of multimedia and interactive content like videos, animations, 에볼루션 바카라 and virtual laboratories. The breadcrumb-like structure of the content assists with navigation and orientation on the vast web site.

For example, the page "Coral Reef Connections" provides a comprehensive overview of coral relationships and their interactions with other organisms, then zooms in on a single clam that is able to communicate with its neighbors and react to changes in the water conditions that occur at the level of the reef. This page, along with the other multidisciplinary, multimedia and interactive pages on the site, offer an excellent introduction to a broad variety of topics in evolutionary biology. The content also includes a discussion of the role of natural selection as well as the concept of phylogenetic analysis, which is an important method to understand evolutionary change.

Evolutionary Theory

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

One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that offers both the depth and breadth of its educational resources. The site offers a variety of interactive learning modules. It also has an "bread crumb structure" that assists students in moving away from the cartoon-like style that is used in Understanding Evolution and 에볼루션 코리아 onto elements on this large website more closely linked to the realms of research science. For instance, an animation introducing the notion of genetic inheritance leads to a page that focuses on John Endler's artificial selection experiments using guppies in the ponds of his native country of Trinidad.

Another useful resource is the Evolution Library on this web website, which includes an extensive library of multimedia assets related to evolution. The content is organized according to curriculum-based pathways that correspond to the learning goals set forth in biology standards. It includes seven short videos designed specifically for use in classrooms, and can be streamed for no cost or 바카라 에볼루션 purchased on DVD.

Evolutionary biology remains a field of study that poses many important questions, including what causes evolution and how fast it takes place. This is particularly relevant for the evolution of humans, where it was difficult to reconcile religious beliefs that held that humanity has a special place in the creation and a soul with the idea that innate physical traits evolved from Apes.

There are a myriad of other ways in which evolution can occur and 에볼루션 바카라 사이트 natural selection being the most popular theory. Scientists also study different types like mutation, genetic drift and sexual selection.

Although many scientific fields of study have a conflict with literal interpretations found in religious texts, evolution biology has been the subject of intense controversy and 에볼루션 무료체험 opposition from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the ideas of evolution, others haven't.
