Evolution Site - Teaching About Evolution

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

This site, a companion to the PBS program that provides teachers with resources which support evolution education while avoiding the types of misconceptions that can hinder it. It's organized in a "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complex and difficult subject to teach well. It is often misunderstood by non-scientists, and even scientists use a definition that confuses the issue. This is particularly relevant when it comes to the nature of the words themselves.

It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and helpful manner. It is a companion for the 2001 series, but also a resource on its own. The information is presented in an organized way that makes it easy to navigate and comprehend.

The site defines terms such as common ancestor, gradual process and adaptation. These terms help to define the nature and relationship of evolution to other concepts in science. The website then provides an overview of how the concept of evolution has been researched and confirmed. This information can help dispel myths created by creationists.

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

Adaptation is the process of changing hereditary traits to become better suited to an environment. This is a result of natural selection, which happens when organisms with better-adapted characteristics are more likely to survive and reproduce than those with less adaptable traits.

Common ancestor: The latest common ancestor of two or more species. By analyzing DNA from these species, it is possible to determine the common ancestor.

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

Coevolution is a relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be observed through the interaction between predator and prey, or parasites and hosts.

Origins

Species (groups that can interbreed) develop through a series of natural changes in the traits of their offspring. These changes can be caused by numerous factors, like natural selection, gene drift and mixing of the gene pool. The evolution of a new species could take thousands of years, and the process may be slowed down or speeded up by environmental factors like climate change or competition for food or habitat.

The Evolution site tracks the development of a number of different animal and plant groups through time with a focus on the key changes that took place in the evolution of each group's history. It also explores human evolution and is a subject that is of particular interest for students.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The famous skullcap, along with the bones that accompanied it were 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 published in 1858, 에볼루션 바카라 무료 a year after the first edition of The Origin. Origin.

The site is primarily an online biology resource however it also includes lots of information about paleontology and geology. Among the best features of the website are a series of timelines which show how climatic and 바카라 에볼루션 바카라 무료체험 (http://www.e10100.com/Home.Php?mod=Space&uid=2870229) geological conditions changed over time, as well as a map of the distribution of some of the fossil groups featured on the site.

While the site is a companion piece to a PBS television show but it also stands on its own as a great source for 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 에볼루션코리아 the more specialized features of the museum's website. These links make it easier 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 animals, plants and insects. Paleobiology is the study of these creatures within their geological context and has numerous advantages over modern observational and experimental methods of examining evolutionary phenomena. Paleobiology is able to study not just the processes and events that take place frequently or over time, but also the distribution and frequency of different species of animals in space throughout the geological time.

The Web site is divided into a variety of paths to learning evolution that include "Evolution 101," which takes the user on a linear path through the science of nature and the evidence to support the theory of evolution. The course also focuses on common misconceptions about evolution and the evolution theory's history.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that support a variety levels of curriculum and teaching methods. The site has a range of multimedia and 에볼루션 사이트 interactive resources that include videos, animations, and virtual labs in addition to general textual content. The breadcrumb-like organization of the content assists with navigation and orientation on the massive Web site.

The page "Coral Reef Connections", for example, gives a brief overview of the relationships between corals, their interaction with other organisms, 에볼루션 바카라 무료체험 and then is enlarged to show one clam, 에볼루션코리아 which is able communicate with its neighbors and react to changes in the conditions of the water at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the website, provide an excellent introduction to a broad spectrum of topics in evolutionary biology. The material also provides an explanation of the role of natural selection and the concept of phylogenetic analysis which is a crucial method to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that connects all branches of biology. A vast collection of books helps in teaching evolution across the life science disciplines.

One resource, which is a companion to the PBS television series Understanding Evolution, is an excellent example of an Web site that provides depth and a variety of educational resources. The site offers a range of interactive learning modules. It also features an "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 related to the realms of research science. An animation that introduces students to the concept of genetics, which links to a page that highlights John Endler's experiments with artificial selection using guppies on native ponds in Trinidad.

The Evolution Library on this website contains a large multimedia library of assets related to evolution. The content is organized into curriculum-based pathways that correspond to the learning goals set forth in biology standards. It contains seven videos that are designed for use in classrooms. They can be viewed online or purchased as DVDs.

Many important questions remain at the heart of evolutionary biology, including what causes evolution to occur and the speed at which it occurs. This is particularly relevant to human evolution, where it has been difficult to reconcile the idea that the physical characteristics of humans were derived from apes and religious beliefs that claim that humanity is unique among living things and has an exclusive place in the creation, with soul.

There are a variety of other ways in which evolution could occur and natural selection being the most well-known theory. However scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among other things.

Many fields of inquiry conflict with literal interpretations of religious texts evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. Certain religions have embraced their beliefs with evolution, but others haven't.
