Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, there are still a lot of misconceptions regarding evolution. People who have been exposed to pop science nonsense often assume that biologists are saying they do not believe in evolution.

This rich Web site, a companion to the PBS program, provides teachers with materials which support evolution education, while avoiding the kinds of misconceptions that can undermine it. It's laid out in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complex and challenging subject to teach effectively. It is often misunderstood by non-scientists, and even scientists have been guilty of using a definition that confuses the issue. This is especially relevant to discussions about the meaning of the word itself.

It is therefore crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The site is a companion to the series that first aired in 2001, but it also functions as an independent resource. The content is presented in a way which aids navigation and orientation.

The site defines terms such as common ancestor, gradual process and adaptation. These terms help frame the nature of evolution as well as its relationship to other scientific concepts. The site gives a comprehensive overview of the way the concept of evolution has been examined. This information can be used to dispel misconceptions that have been engendered by creationists.

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

Adaptation is the tendency of heritable traits to become better suited to an 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 에볼루션 슬롯 (what is it worth) (also called common ancestor) The most recent ancestor shared by two or more species. The common ancestor can be identified by analyzing the DNA of the species.

Deoxyribonucleic Acid: A massive biological molecular that holds the necessary information for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are the source of new genetic information within cells.

Coevolution is a relation between two species in which the evolutionary changes of one species are influenced evolutionary changes in the other. Coevolution is evident in the interaction of predator and prey, 에볼루션 슬롯게임 [read more on Bookmarkingbay`s official blog] or 에볼루션 무료체험 사이트 (Evolutioncasino78766.blogdun.com) parasite and hosts.

Origins

Species (groups that can crossbreed) change through a series of natural changes in their offspring's traits. The changes can be caused by a variety of factors that include natural selection, genetic drift, and mixing of genes. The development of a new species could take thousands of years and the process could be slowed down or accelerated by environmental factors like climate change or the competition for food or habitat.

The Evolution site tracks the evolution of various groups of animals and plants over time with a focus on the key changes that took place in the evolution of each group's history. It also focuses on human evolution and is a subject that is of particular interest to students.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been 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 believed as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, one year after the first edition of the Origin was published, it is highly unlikely that Darwin had seen or 에볼루션 슬롯 heard of it.

While the site focuses on biology, it also includes a good deal of information on geology and paleontology. The Web site has numerous features that are particularly impressive, including a timeline of how climate and geological conditions have changed over the course of time. It also includes an interactive map that shows the location of fossil groups.

While 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 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 Web site. These hyperlinks make it easy to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler’s experiments with guppies, which demonstrate 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 geographical context and offers a number of advantages over the modern observational and research methods for analyzing evolutionary phenomena. In addition to examining the processes and events that happen frequently or over a long period of time, paleobiology can be used to study the relative abundance of different kinds of organisms as well as their distribution throughout the geological time.

The site is divided up into various routes that can be taken to study the subject of evolution. One of the paths, "Evolution 101," walks the reader through the complexities and evidence of evolution. The path also explores misconceptions about evolution and also the history of evolutionary thinking.

Each of the main sections of the Evolution website is equally well-developed, with materials that are suited to a variety of levels of curriculum and teaching methods. The site has a range of multimedia and interactive resources, including animations, video clips and virtual laboratories, in addition to its general textual content. The breadcrumb-like organization of the content aids in navigation and 에볼루션 슬롯 orientation on the massive website.

For instance, the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interactions with other organisms. It then zooms in on a single clam that is able to communicate with its neighbors and respond to changes in water conditions that take place at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, offers a great introduction to many topics in evolutionary biology. The content also includes an overview of the importance of natural selection and the concept of phylogenetic analysis, which is an important tool in understanding evolutionary change.

Evolutionary Theory

For biology students the concept of evolution is a major thread that weaves together all the branches of the field. A wide selection of resources helps teachers teach evolution across the disciplines of life science.

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of a Web site that provides depth as well as broadness in terms of educational resources. The site features a wealth of interactive learning modules. It also has a "bread crumb structure" that assists students in moving away from the cartoon style of Understanding Evolution and onto elements on this large website more closely connected to the worlds of research science. Animation that introduces the concept of genetics, which links to a page highlighting John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.

Another helpful resource is the Evolution Library on this Web website, which includes an extensive library of multimedia items connected to evolution. The contents are organized into curriculum-based paths that parallel the learning objectives set out in the standards for biology. It includes seven short videos designed specifically for 에볼루션바카라 classroom use, which can be streamed at no cost or purchased on DVD.

Evolutionary biology remains a field of study that poses many important questions, such as what causes evolution and the speed at which it happens. This is particularly true for humans' evolution which was a challenge to reconcile religious beliefs that held that humanity has a special place in creation and a soul with the notion that our physical traits originated from Apes.

Additionally, there are a number of ways that evolution could be triggered and natural selection is the most popular theory. Scientists also study different types such as mutation, 에볼루션 무료체험 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. Some religions have reconciled their beliefs with evolution, while others haven't.
