The History Of Evolution Site In 10 Milestones

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution remain. People who have been exposed to popular science myths often assume that biologists claim they do not believe in evolution.

This rich website - companion to the PBS series offers teachers with resources which support evolution education and avoid the kinds of myths that make it difficult to understand. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It's difficult to effectively teach evolution. It is often misunderstood by non-scientists, and even scientists are guilty of using a definition that confuses the issue. This is particularly relevant to debates about the definition of the word itself.

It is important to define terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. The site is a companion to the series that first aired in 2001, but it is also an independent resource. The material is presented in an organized manner that makes it simpler to navigate and understand.

The site defines terms such as common ancestor (or common ancestor), gradual process and adaptation. These terms help frame the nature and significance of evolution with other scientific concepts. The site also provides an overview of how the concept of evolution has been researched and validated. This information can be used to dispel the myths that have been created by the creationists.

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

Adaptation is the tendency of heritable traits to be more suited to the environment. This is the result of natural selection. Organisms that have better-adapted traits are more likely than those with less-adapted traits to reproduce and 에볼루션 코리아 (Http://planforexams.Com) survive.

Common ancestor 에볼루션사이트 (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 determine the common ancestor.

Deoxyribonucleic Acid: A massive biological molecular that holds the information required for cell replication. The information is stored in nucleotides arranged in sequences that are strung together into long chains, also known as chromosomes. Mutations are the cause of new genetic information in cells.

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

Origins

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

The Evolution site tracks the evolution of a variety of animal and plant groups through time, focusing on the major transitions that occurred in the evolution of each group's history. It also focuses on the evolutionary origin of humans, a topic that is crucial for students to comprehend.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of human beings had been discovered. The famous skullcap, with the bones associated with it were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now recognized as an early Homo neanderthalensis. Although the skullcap was not published until 1858, which was one year after the first edition of the Origin was published, it is extremely unlikely that Darwin had heard or seen of it.

The site is primarily one of biology, but it also contains many details on geology and paleontology. One of the most appealing features of the Web site are a series of timelines that show how climatic and geological conditions have changed over time as well as a map of the distribution of a few fossil groups listed on the site.

The site is a companion to the PBS TV series but it can also be used as an educational resource by teachers and students. The site is extremely 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 components of the museum's Web site. These links facilitate the transition 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 plants, animals, and insects. Paleobiology is the study of these creatures in their geological environment, has many advantages over modern observational or research methods for exploring evolutionary phenomena. Paleobiology focuses on not just the processes and events that happen regularly or over time, but also the distribution and frequency of different species of animals in space over the course of geological time.

The website is divided into various paths that can be chosen to study the subject of evolution. One of the paths, "Evolution 101," walks the reader through the complexities and evidence 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 on the Evolution website is equally well-developed, with materials that are suited to a variety of educational levels and teaching styles. The site includes a variety of multimedia and interactive resources, including animations, video clips and virtual laboratories as well as general textual content. The content is laid out in a nested bread crumb style that facilitates navigation and orientation on the Web site.

The page "Coral Reef Connections", for 에볼루션 게이밍 룰렛; fox-devine.Hubstack.net, example, provides an overview of coral relationships, their interaction with other organisms, and then is enlarged to show one clam that is able to communicate with its neighbors and react to changes in water conditions that occur on the reef level. This page, as well as the other multidisciplinary, multimedia and interactive pages on the site, provide an excellent introduction to the broad range of topics in evolutionary biology. The content also includes a discussion on the significance of natural selectivity and the concept of phylogenetics as a key method for understanding the evolution of changes.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A wide range of resources helps teachers teach about evolution across all life sciences.

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of a Web site that provides the depth and the broadness in terms of educational resources. The site has a wide array of interactive learning modules. It also features an "bread crumb structure" that helps students move away from the cartoon-like style used in Understanding Evolution and onto elements on this large website more closely connected to the fields of research science. An animation that introduces the concept of genetics, which links to a page about John Endler's artificial-selection experiments with Guppies in native ponds in Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related with evolution. The content is organized into curriculum-based pathways that correspond to the learning objectives set out in the standards for biology. It includes seven short videos specifically designed for use in the classroom, and 무료 에볼루션 can be streamed at no cost or purchased on DVD.

A variety of crucial questions remain in the midst of evolutionary biology, including what triggers evolution and the speed at which it occurs. This is particularly relevant to human evolution, where it's been difficult to reconcile the notion that the physical characteristics of humans evolved from apes with religious beliefs that claim that humanity is unique in the universe and has an enviable place in creation, with a soul.

Additionally there are a myriad of ways in which 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 fields of scientific inquiry are in conflict with the literal interpretations of the Bible, evolutionary biology has been the subject of intense controversy and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, others have not.
