Evolution Site - Teaching About Evolution

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

This site, which is a companion to the PBS series - provides teachers with materials that promote evolution education and avoid the kinds of myths that hinder it. It's organized in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It's difficult to properly teach evolution. Non-scientists often misunderstand the subject and some scientists use a definition which confuses it. This is especially relevant to discussions about the meaning of the word itself.

Therefore, it is essential to define terms that are used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful way. The site is a companion to the show which first aired in 2001, but also functions as an independent resource. The content is organized in a manner that makes it simpler to navigate and understand.

The site defines terms such as common ancestor and gradual process. These terms help to frame the nature of evolution as well as its relation to other concepts in science. The website then provides an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel myths that are created by the creationists.

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

Adaptation is the tendency of heritable traits to be more suitable to their environment. This is due to natural selection, which occurs when organisms that are better adapted characteristics are more likely to survive and reproduce than those with less adapted characteristics.

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

Deoxyribonucleic Acid: A huge biological molecular containing the information needed for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is a relation between two species where evolution of one species influence evolutionary changes of the other. Coevolution can be observed in the interactions between predator and prey, or parasite and 에볼루션 블랙잭 hosts.

Origins

Species (groups of individuals that can interbreed) develop through an array of natural changes in the characteristics of their offspring. These changes are caused by a variety of factors that include natural selection, genetic drift and 에볼루션 블랙잭 gene pool mixing. The development of a new species could take thousands of years, and 에볼루션 무료 바카라 블랙잭 (Xintangtc.com) the process may be slowed down or accelerated due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site traces the emergence of a variety of species of plants and animals over time and focuses on the most significant transitions that occurred in the history of each group. It also focuses on human evolution as a subject of particular importance to students.

When Darwin wrote the Origin of Species, only a handful of antediluvian human fossils had been found. The famous skullcap, along with the associated bones 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 first published in 1858, one year after the publication of the first edition of The Origin. Origin.

The site is mostly one of biology however it also includes many details on paleontology and geology. Among the best features of the website are a timeline of events that show how geological and 에볼루션 코리아 climatic conditions have changed over time and an interactive map of the distribution of some fossil groups that are featured on the site.

The site is a companion to a PBS TV series but it can also be used as a source for teachers and students. The site is very well-organized and offers clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum Web site. These hyperlinks make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are links to John Endler's experiments with guppies. They illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life has resulted in a variety of animals, plants and insects. Paleobiology is the study of these creatures in their natural environment and has a number of advantages over the modern observational and research methods for analyzing evolutionary processes. Paleobiology focuses on not just the processes and events that take place regularly or over time, but also the relative abundance and distribution of various animal groups in space throughout geological time.

The Web site is divided into several optional paths to learning evolution that include "Evolution 101," which takes the viewer on a line through the scientific process and the evidence supporting the theory of evolution. The path also explores misconceptions about evolution, and the background of evolutionary thinking.

Each of the main sections of the Evolution website is equally well-developed, and includes materials that support a variety educational levels and teaching styles. In addition to general textual content, the site features an extensive selection of multimedia and interactive content, such as video clips, animations, and virtual labs. The content is laid out in a nested bread crumb-like fashion that helps with navigation and orientation within the vast web site.

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

Evolutionary Theory

Evolution is an underlying thread that runs through all branches of biology. A wide range of resources helps teachers teach about evolution across the life sciences.

One resource, the companion to PBS's TV series Understanding Evolution is an excellent example of an Web page that offers both depth as well as broadness in terms of educational resources. The site has a variety of interactive learning modules. It also features an "bread crumb structure" that allows students to move away from the cartoon style that is used in Understanding Evolution and onto elements on this site that are more closely connected to the realms of research science. Animation that introduces the concept of genetics links to a page about John Endler's experiments in artificial selection using guppies on native ponds in Trinidad.

Another resource that is worth mentioning is the Evolution Library on this website, which includes an extensive collection of multimedia assets connected to evolution. The content is organized into curriculum-based paths that parallel the learning objectives outlined in the biology standards. It includes seven short videos specifically designed for use in the classroom, and can be streamed for no cost or purchased on DVD.

A variety of crucial questions remain in the midst of evolutionary biology, such as what triggers evolution and how fast it occurs. This is especially true for the evolution of humans where it was a challenge to reconcile religious beliefs that humanity has a special place in creation and a soul with the notion that human beings have innate physical traits originated from Apes.

There are a variety of other ways evolution can occur and natural selection being the most popular theory. Scientists also study other kinds such as genetic drift, and sexual selection.

Many fields of inquiry are in conflict with literal interpretations of religious texts, evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. Certain religions have embraced their beliefs to evolution but others haven't.
