It is based on a variety of well-established and observable facts such as the fact that more offspring are produced than could possibly survive; that individuals differ from each other in their physical characteristics (phenotype) and that distinct traits confer varying rates of reproduction and survival; and that traits can be passed on to the next generation.

Therefore, the theory of evolution has been repeatedly proven out, as have the related theories of Copernican, germ and atomic theory.<br><br>What is the Process of Evolution?<br><br>The process of evolution is the gradual shift over time in the ratio of genetically distinct individuals within a certain species. This change is a result of the natural selection of those who are better adapted to their environment. The better-adapted individuals have a greater chance of survival and reproduction.

Evolution Site - Teaching About Evolution

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

This site, a companion to the PBS program offers teachers resources that support the evolution of education, while avoiding the kinds of misconceptions that can hinder it. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It's not easy to teach evolution well. People who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. This is especially relevant to debates about the definition of the word itself.

It is essential to define terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful manner. The website is a companion to the show that premiered in 2001, but it is also an independent resource. The content is organized in a way that makes it easy to navigate and understand.

The site defines terms such as common ancestor and the gradual process. These terms help frame the nature and relationship of evolution to other concepts in science. The site then offers an overview of how the concept of evolution has been researched and validated. This information can be used to dispel myths that have been engendered by the creationists.

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

Adaptation: The tendency for heritable traits to become better adaptable to a specific environment. This is a result of natural selection. Organisms with better-adapted characteristics are more likely than those with less-adapted traits to survive and reproduce.

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

Deoxyribonucleic acid: A massive biological molecule that contains information required for cell replication. The information is stored in sequences of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution is evident in the interactions between predator and prey, or parasite and hosts.

Origins

Species (groups of individuals who can interbreed) develop through a series of natural changes in the characteristics of their offspring. These changes are caused by a variety that include natural selection, genetic drift, and mixing of gene pools. The evolution of new species could take thousands of years. Environmental conditions, like climate change or competition for food and habitat can slow or speed up the process.

The Evolution site tracks the development of a variety of animal and plant groups through time, focusing on the major shifts that occurred throughout the evolution of each group's history. It also examines the evolutionary origin of humans, a topic that is especially important for students to comprehend.

Darwin's Origin was published in 1859, at a time when only a handful of antediluvian fossils of human beings had been discovered. The most famous among them was the skullcap and bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was a year before the first edition of the Origin was published, it is extremely unlikely that Darwin had heard or seen of it.

The site is mostly a biology site, but it also contains many details on geology and paleontology. The Web site has a number of features that are particularly impressive, including the timeline of how geological and climate conditions have changed over the course of time. It also has a map showing the distribution of fossil groups.

The site is a companion for the PBS TV series but it can be used as a resource by 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 assistance) and the more specialized features of the museum website. These hyperlinks help users move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are links to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of animals, 에볼루션사이트 plants and insects. Paleobiology, the study of these creatures within their natural environment, has many advantages over modern observational or experimental methods of studying evolutionary phenomena. In addition to exploring the processes and events that happen regularly or over a lengthy period of time, paleobiology allows to examine the relative abundance of various species of organisms and 에볼루션 슬롯 (Our Web Site) their distribution across geological time.

The Web site is divided into several optional paths to learning evolution that include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence to support the theory of evolution. The path also reveals common misconceptions about evolution as well as the evolution of thought.

Each of the main sections on the Evolution website is equally well-developed, with materials that are suited to a variety of curriculum levels and teaching styles. The site has a range of multimedia and interactive resources which include animations, video clips and virtual laboratories in addition to general textual content. The content is organized in a nested, bread crumb style that facilitates navigation and orientation within the vast Web site.

The page "Coral Reef Connections", for example, provides a comprehensive overview of the relationships between corals and their interactions with other organisms, and then zooms in to one clam, which is able to communicate with its neighbours and respond to changes in water conditions that occur on the reef level. This page, as well as the other multidisciplinary multimedia and interactive pages, offers a great introduction to the many areas of evolutionary biology. The content also includes an explanation of the role of natural selectivity and the concept of phylogenetics analysis, an important tool to understand evolutionary change.

Evolutionary Theory

Evolution is a common thread that runs through 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 an Web page that offers both the depth and the broadness in terms of educational resources. The site features a wide range of interactive learning modules. It also has a "bread crumb structure" that helps students move away from the cartoon style that is used in Understanding Evolution and onto elements on this site that are more closely related to the worlds of research science. For instance an animation that introduces the notion of genetic inheritance leads to a page that highlights John Endler's artificial selection experiments with guppies in native ponds of Trinidad.

Another helpful resource is the Evolution Library on this Web site, which contains an extensive collection of multimedia resources that are related to evolution. The content is organized into curricula-based pathways that correspond to the learning objectives outlined in the standards for biology. It includes seven short videos specifically designed for 에볼루션 게이밍 use in classrooms, and can be streamed for no cost or purchased on DVD.

A number of important questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it happens. This is particularly true in the case of human evolution where it was a challenge to reconcile religious beliefs that held that humanity has a unique position in the universe and 무료 에볼루션 a soul with the idea that innate physical traits originated from the apes.

There are a myriad of other ways in which evolution could occur and natural selection being the most popular theory. Scientists also study other kinds like mutation, genetic drift and sexual selection.

While many fields of scientific inquiry are in conflict with literal interpretations of religious texts, evolutionary biology has been the subject of particularly controversial debate and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the ideas of evolution, other religions have not.
