10 Books To Read On Evolution Site

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, 에볼루션코리아 misinformation about evolution remain. People who have taken in popular science myths often assume that biologists are saying they do not believe in evolution.

This rich website - companion to the PBS series offers teachers with resources that support evolution education and avoid the kinds of misinformation that can hinder it. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It's not easy to properly teach evolution. It is often misunderstood even by non-scientists, and even some scientists use a definition that confuses the issue. This is particularly relevant when discussing the nature of the words themselves.

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 helpful manner. The site is a companion to the series that first aired in 2001, but it also functions as an independent resource. The information is organized in a manner that makes it easier to navigate and understand.

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

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

Adaptation: The tendency for heritable traits to become better suited to a particular environment. This is the result of natural selection, which happens when organisms that are more adaptable traits are more likely to survive and reproduce than those with less adapted characteristics.

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

Deoxyribonucleic acid: A massive biological molecule that contains the information needed for cell replication. The information is contained in sequences of nucleotides that are strung together to form long chains, called chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is a relationship between two species where 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 host and parasite.

Origins

Species (groups of individuals that are able to interbreed) change through an array of natural changes in the traits of their offspring. Changes can be caused by various factors, including natural selection, gene drift, and mixing of the gene pool. The evolution of a new species can take thousands of years and the process can 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 number of different groups of animals and plants over time with a focus on the key shifts that occurred throughout the evolution of each group's history. It also examines the evolution of humans, which is a topic 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 most famous among them was the skullcap and 에볼루션 무료 바카라 the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. While the skullcap wasn't published until 1858, one year after the first edition of the Origin appeared, it is very unlikely that Darwin had ever heard of it.

While the site is focused on biology, it contains a wealth of information about geology as well as paleontology. One of the most appealing features of the website are a timeline of events that illustrate the way in which climatic and geological conditions have changed over time as well as an interactive map of the distribution of a few fossil groups that are featured on the site.

The site is a companion for a PBS TV series but it could 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 specific elements of the museum Web site. These hyperlinks help users move from the engaging cartoon style of the Understanding Evolution pages to the more sophisticated world of research science. In particular there are hyperlinks to John Endler's experiments using Guppies that demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced a variety of animals, plants and insects. Paleobiology is the study of these creatures in their geological context and has many advantages over the modern observational and research methods in its exploration of evolutionary processes. Paleobiology focuses on not only the process and events that occur regularly or over time, but also the distribution and frequency of different groups of animals across geological time.

The site is divided into several routes that can be taken to gain knowledge about evolution. One of these paths, "Evolution 101," takes the viewer through the complexities and evidence of evolution. The path also examines myths about evolution and the background of evolutionary thinking.

Each of the other sections of the Evolution site is similarly created, with resources that can be used to support a range of curriculum levels and pedagogical styles. In addition to the standard textual content, the site also has an array of multimedia and interactive content, such as video clips, animations, and virtual labs. The content is laid out in a nested bread crumb style that facilitates navigation and orientation within the large Web site.

The page "Coral Reef Connections", for example, provides an overview of coral relationships and their interactions with other organisms, and then zooms in on one clam that is able communicate with its neighbors and react to changes in the water conditions that occur on the reef level. This page, along with the other multidisciplinary interactive and 에볼루션 블랙잭 무료 바카라 (Ongoing) multimedia pages, offers a great introduction to many topics in evolutionary biology. The material includes an overview of the role of natural selectivity and the concept phylogenetics analysis which is a crucial tool to understand evolutionary changes.

Evolutionary Theory

Evolution is a common thread that is found throughout all branches of biology. A wide selection of resources helps teachers teach evolution across the life science disciplines.

One resource, which is the companion to PBS's television show Understanding Evolution is an excellent example of an Web page that provides depth as well as wide range of educational resources. The site offers a variety of interactive learning modules. It also features a "bread crumb structure" that helps students move away from the cartoon-like style used in Understanding Evolution and onto elements on this large website more closely linked to the fields of research science. For example, an animation introducing the notion of genetic inheritance leads to a page that focuses on John Endler's experiments in artificial selection using guppies in the ponds of his native country of Trinidad.

The Evolution Library on this website is a vast multimedia library of materials that deal with evolution. The content is organized according to the form of curriculum-based pathways that are in line with the learning objectives set out in biology standards. It contains seven short videos specifically designed for classroom use. They can be viewed online or purchased as DVDs.

Evolutionary biology is an area of study that poses many important questions, such as what triggers evolution and how fast it takes place. This is particularly relevant for humans' evolution where it was a challenge to reconcile religious beliefs that held that humanity has a special place in creation and a soul with the idea that innate physical traits were derived from apes.

There are a myriad of other ways evolution can occur, with natural selection as the most widely accepted theory. Scientists also study different types such as genetic drift, and sexual selection.

While many scientific fields of study are in conflict with literal interpretations found in religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, other religions have not.
