Evolution Site - Teaching About Evolution

Despite the best efforts of biology teachers, misinformation about evolution remain. People who have been exposed to pop science nonsense often assume that biologists don't believe in evolution.

This rich Web site, which is a complement to the PBS program, provides teachers with materials that promote evolution education, 무료에볼루션 while avoiding the kinds of misconceptions which hinder it. It's laid out in a "bread crumb" format to facilitate navigation and orientation.

Definitions

It's not easy to teach evolution well. It is often misunderstood by non-scientists and even scientists have been guilty of using definitions that confuse the issue. This is especially relevant to debates about the definition of the word itself.

Therefore, it is crucial to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful way. It is a companion for the 2001 series, but it is also a resource on its own. The content is presented in a nested fashion that aids navigation and orientation.

The site defines terms such as common ancestor, the gradual process, and 바카라 에볼루션 adaptation. These terms help define the nature of evolution and its relationship to evolution with other scientific concepts. The website then provides an overview of how the concept of evolution has been vetted and verified. This information can be used to dispel misconceptions that have been propagated by the creationists.

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

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

Common ancestor: The most recent common ancestor of two or more distinct species. The common ancestor can be identified by studying the DNA of the species.

Deoxyribonucleic Acid: A massive biological molecular that holds the information needed for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are responsible for the creation 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 can be observed through the interaction between predator and prey, or parasite and hosts.

Origins

Species (groups that can interbreed) develop through a series of natural changes in their offspring's traits. The causes of these changes are various factors, including natural selection, gene drift, and mixing of the gene pool. The evolution of new species can take thousands of years. Environmental conditions, such as climate changes or competition for food and habitat, can slow or accelerate the process.

The Evolution site tracks the development of a number of different animal and plant groups through time and focuses on the most significant changes that took place in the history of each group. It also explores human evolution, 에볼루션 룰렛 which is a topic that is particularly important for students.

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

The site is primarily one of biology however it also includes lots of information about geology and paleontology. The Web site has a number of features that are particularly impressive, such as 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 a great source for teachers and students. The site is very well organized and provides 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 links make it easier to transition from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. Particularly there are links to John Endler's experiments using guppies that illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to a variety of plants, animals and insects. Paleobiology is the study of these creatures within their geographical context and offers a number of advantages over the modern observational and research methods in its exploration of evolutionary processes. Paleobiology is able to study not just the processes and events that happen regularly or over time, but also the distribution and frequency of different groups of animals across geological time.

The website is divided into a variety of ways to learn about 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 misconceptions about evolution and the background of evolutionary thought.

Each of the other main sections of the Evolution site is similarly developed, with materials that support a variety of curriculum levels and 에볼루션 룰렛 pedagogical styles. The site includes a variety of interactive and multimedia content which include animations, video clips and virtual laboratories in addition to general textual content. The content is organized in a nested, bread crumb fashion that aids navigation and 에볼루션 코리아 orientation within the vast web site.

The page "Coral Reef Connections", for example, provides a comprehensive overview of the relationships between corals, their interaction with other organisms and then is enlarged to show one clam that can 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 interactive and multimedia pages provides an excellent introduction to many 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 change.

Evolutionary Theory

For biology students evolution is a crucial thread that connects all branches of the field. A vast collection of resources can help teachers teach about evolution across all life sciences.

One resource, the companion to PBS's television series Understanding Evolution is an excellent example of a Web site that provides depth and wide range of educational resources. The site offers a range of interactive learning modules. It also has an embedded "bread crumb" structure that helps students move from the cartoon-like style of Understanding Evolution to elements on this huge site that are closer to the field of research science. An animation that introduces students to the concept of genetics links to a page about John Endler's experiments in artificial selection using Guppies living in ponds native to Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related to evolution. The content is organized into courses that are based on curriculum and 에볼루션 바카라 무료체험 follow the learning objectives outlined in the standards for biology. It includes seven short videos designed specifically for use in the classroom, and can be streamed for free or purchased on DVD.

A variety of crucial questions remain in the midst of evolutionary biology, such as the factors that trigger evolution and the speed at which it occurs. This is particularly relevant to human evolution, which has made it difficult to reconcile the idea that the innate physical characteristics of humans evolved from apes with religious beliefs that claim that humanity is unique among living things and 에볼루션 바카라 체험 has an exclusive place in the creation with a soul.

There are also a number of other ways in which evolution can take place and natural selection being the most well-known theory. However scientists also study other types of evolution such as mutation, genetic drift, and sexual selection, among others.

While many fields of scientific inquiry conflict with the literal interpretations of religious texts, 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 notions of evolution, others haven't.
