Evolution Site - Teaching About Evolution

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

This rich Web site, which is a companion to the PBS program that provides teachers with resources that promote evolution education while avoiding the types of misconceptions that can undermine it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

Evolution is a complex and 에볼루션바카라사이트 difficult subject matter to teach well. Non-scientists often misunderstand the subject, and some scientists even use a definition that confuses it. This is especially true when discussing the meaning of the words themselves.

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 serves as an accompanying site for the 2001 series, but also a resource on its own. The material is organized in a way that makes it easy to navigate and comprehend.

The site defines terms such as common ancestor and the gradual process. These terms help define the nature of evolution and its relationship to evolution with other scientific concepts. The website provides a summary of the ways the concept of evolution has been examined. This information can be used to dispel myths that have been propagated by the creationists.

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

Adaptation is the process of changing hereditary traits to become more suitable to their environment. This is the result of natural selection. It occurs when organisms that have better-adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.

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

Deoxyribonucleic Acid: A large biological molecular containing the information needed for cell replication. The information is stored in nucleotide sequences that are strung into long chains, referred to as chromosomes. Mutations are the basis for new genetic information within cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes 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 characteristics of their offspring. The causes of these changes are numerous factors, like natural selection, gene drift, and mixing of the gene pool. The evolution of new species could take thousands of years. Environmental conditions, 에볼루션 사이트 such as climate change or competition for food and habitat can impede or accelerate the process.

The Evolution site follows the emergence of various groups of animals and plants, focusing on major transitions in each group's past. It also focuses on the evolutionary history of humans, a topic that is crucial for students to know.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been found. The skullcap that is famous, along with the bones that accompanied it, was discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now known as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, a year after the publication of the first edition of The Origin.

The site is mostly a biology site however it also includes lots of information about paleontology and geology. The website has numerous features that are particularly impressive, including a timeline of how geological and climate conditions have changed over time. It also includes maps that show the locations of fossil groups.

While the site is a companion to a PBS television series, it also stands on its own as an excellent source for teachers and students. The site is well-organized and provides clear links to the introduction content of Understanding Evolution (developed under the National Science Foundation's funding) and 에볼루션 카지노 the more specialized features of the museum website. These hyperlinks make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are also links to John Endler's experiments with guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to an array of animals, plants and insects. Paleobiology is the study of these creatures within their geological context and has a number of advantages over modern observational and experimental methods in its exploration of evolutionary phenomena. Paleobiology can examine not only processes and events that take place regularly or over time, 에볼루션카지노사이트 but also the distribution and frequency of different groups of animals in space over the course of the geological time.

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

Each of the other major sections of the Evolution site is equally developed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. In addition to the general textual content, the site also has an extensive selection of multimedia and interactive content like videos, animations and virtual laboratories. The content is laid out in a nested bread crumb fashion that aids navigation and orientation within the vast web site.

The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of the coral's relationships, their interaction with other organisms and then zooms in to one clam that can communicate with its neighbours and respond to changes in conditions of the water at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages gives a good introduction to the many areas of evolutionary biology. The material also provides an overview of the importance of natural selection as well as the concept of phylogenetic analysis, which is a key tool for understanding the evolution of change.

Evolutionary Theory

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

One resource, which is the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that provides depth and broadness in terms of educational resources. The site offers a variety of interactive learning modules. It also features an embedded "bread crumb" structure that allows students to move from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the world of research science. An animation that introduces the concept of genetics, which links to a page that highlights John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.

Another useful resource is the Evolution Library on this site, which has an extensive library of multimedia assets related to evolution. The contents are organized into curriculum-based paths that parallel the learning objectives outlined in the standards for biology. It contains seven videos specifically designed for use in classrooms, and can be streamed at no cost or purchased on DVD.

Many important questions remain at the heart of evolutionary biology, including the factors that trigger evolution and how fast it occurs. This is particularly true in the case of human evolution, where it was difficult to reconcile religious beliefs that held that humans have a distinct place in the creation and a soul with the idea that innate physical traits were derived from apes.

In addition there are a variety of ways that evolution can 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 inquiry have a conflict with literal interpretations of religious texts, evolutionary biology has been the subject of controversial debate and resistance from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, other religions aren't.
