Evolution Site - Teaching About Evolution

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

This rich website - companion to the PBS series - provides teachers with materials that promote evolution education and avoids the kinds of misconceptions that make it difficult to understand. It's laid out in a "bread crumb" format to make navigation and orientation easier.

Definitions

Evolution is a complicated and 에볼루션 무료체험 difficult subject to teach well. Many non-scientists are unable to grasp the concept and some scientists employ a definition that confuses it. This is especially relevant when discussing the meaning of the words themselves.

It is crucial to define the terms that are used in evolutionary biology. Understanding Evolution's website provides this in a straightforward and useful manner. The site is both an accompanying site for the 2001 series, and also a resource on its own. The material is presented in a way which aids navigation and orientation.

The site defines terms such as common ancestor 에볼루션 바카라 (or common ancestor), gradual process, and adaptation. These terms help to frame the nature of evolution as well as its relation to other concepts in science. The website provides a summary of the manner that evolution has been tested. This information can be used to dispel myths that have been created by creationists.

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

Adaptation is the tendency of heritable traits to be better suited to an environment. This is a result of natural selection. It occurs when organisms with better adapted characteristics are more likely to survive and reproduce than those with less adaptable characteristics.

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

Deoxyribonucleic acid: A massive biological molecule that holds the information required for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is the relationship between two species, 에볼루션 사이트 where the evolutionary changes of one species are influenced evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey or the parasite and 에볼루션 사이트 the host.

Origins

Species (groups of individuals that can interbreed) change through an array of natural changes in the characteristics of their offspring. These changes can be caused by numerous factors, like natural selection, gene drift, 에볼루션 사이트 and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental circumstances, such as climate changes or competition for food resources and habitat, can slow or accelerate the process.

The Evolution site traces through time the evolution of various species of plants and animals and focuses on major changes in each group's history. It also examines the evolutionary history of humans which is especially important for students to understand.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. One of them was the infamous skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just a year before the first edition of the Origin was published, it's extremely unlikely that Darwin had heard or seen of it.

The site is primarily an online biology resource however it also includes a lot of information on paleontology and geology. The most impressive features of the website are a timeline of events that illustrate how geological and climatic conditions have changed over time and an outline of the distribution of some fossil groups listed on the site.

Although the site is a companion to a PBS television show but it also stands on its own as a great resource for teachers and students. The site is well-organized and has clear links between the introduction content in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These hyperlinks make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are hyperlinks to John Endler's research with guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of plants, animals and insects. Paleobiology is the study of these creatures in their geological environment is a superior method of study over modern observational or experimental methods for studying evolutionary phenomena. In addition to exploring the processes and events that happen regularly or over a long period of time, paleobiology allows to analyze the relative abundance of different kinds of organisms as well as their distribution across geological time.

The website is divided into several optional paths to learning evolution which include "Evolution 101," which takes the user on a linear path through the nature of science and the evidence supporting the theory of evolution. The course also focuses on common misconceptions about evolution as well as the history of evolutionary thought.

Each of the other major sections of the Evolution site is equally well created, with resources that support a variety of educational levels and pedagogical styles. In addition to the general textual content, the site offers an array of multimedia and interactive resources like videos, animations, and virtual laboratories. 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, provides an overview of the relationships between corals and interactions with other organisms and is enlarged to show one clam, which is able communicate with its neighbours and respond to changes in water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and multimedia pages offers a great introduction to the many areas of evolutionary biology. The information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is a key method to understand evolutionary changes.

Evolutionary Theory

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

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that provides depth and breadth in terms of its educational resources. The site features a wide range of interactive learning modules. It also has a nested "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this large Web site closer to the world of research science. An animation that introduces the concept of genetics, which links 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 web website, which includes an extensive library of multimedia items that are related to evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives outlined in biology standards. It contains seven videos designed specifically for 에볼루션 룰렛 use in the classroom, and can be streamed for no cost or purchased on DVD.

A variety of crucial questions remain at the core of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is especially true for humans' evolution, where it was difficult to reconcile religious beliefs that held that humanity has a unique place in creation and 무료에볼루션 a soul with the idea that innate physical traits were derived from Apes.

In addition, there are a number of ways that evolution could be triggered with natural selection being the most popular theory. Scientists also study other types such as genetic drift, and sexual selection.

While many scientific fields of study conflict with the literal interpretations of religious texts, the concept of evolution biology has been a subject of intense debate and resistance from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
