Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution remain. People who have absorbed the nonsense of pop science often believe that biologists do not believe in evolution.

This rich Web site - companion to the PBS series It provides teachers with materials that support evolution education and avoid the kinds of myths that make it difficult to understand. It's organized in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It's difficult to properly teach evolution. People who are not scientists often have a difficult time understanding the subject, and 에볼루션카지노 some scientists even use a definition which confuses it. This is particularly true when discussing the nature of the words themselves.

Therefore, it is important to define terms used in evolutionary biology. Understanding Evolution's website does this in an easy and helpful manner. The site serves as an accompanying site for the 2001 series, and also a resource on its own. The content is organized in a manner that makes it simpler to navigate and understand.

The site defines terms like common ancestor 에볼루션코리아 and gradual process. These terms help to frame the nature of evolution and its relationship to other scientific concepts. The website then provides an overview of how the concept of evolution has been vetted and confirmed. This information can be used to dispel the myths that have been propagated by creationists.

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

The process of adaptation is the tendency of heritable traits to become better suited to an environment. This is a result of natural selection. Organisms with better-adapted traits are more likely than those with less adapted traits to survive and reproduce.

Common ancestor: The latest common ancestor of two or more different species. The common ancestor can be identified by analyzing the DNA of those species.

Deoxyribonucleic acid: A massive biological molecule that contains information required for cell replication. The information is stored in nucleotide sequences, which are strung into long chains, referred to as chromosomes. Mutations are responsible for the creation of new genetic information within cells.

Coevolution is a relation between two species in which the evolution of one species are influenced by evolutionary changes of the other. Examples of coevolution are the interactions between predator and prey or the parasite and the host.

Origins

Species (groups that can crossbreed) change through a series of natural changes in their offspring's traits. The changes can be caused by a variety of factors such as natural selection, genetic drift, and mixing of gene pools. The development of new species can take thousands of years. Environmental circumstances, such as climate changes or competition for food or habitat, can slow or accelerate the process.

The Evolution site traces the emergence of a variety of animal and plant groups through time, focusing on the major transitions that occurred in each group's history. It also examines the evolution of humans, which is a topic of particular importance to students.

Darwin's Origin was written in 1859, when just a handful of antediluvian fossils of humans were discovered. Among them was the famous skullcap and associated bones found in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap, which was first published in 1858, a year following the initial edition of The Origin.

The site is mostly an online biology resource however it also includes a lot of information on geology and paleontology. Among the best features on the site are a series of timelines which show how geological and 에볼루션 무료 바카라카지노사이트 (fatahal.com) climatic conditions have changed over time, as well as an outline of the distribution of some fossil groups listed 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 resource for teachers and students. The site is well-organized, and provides clear links to the introductory information of Understanding Evolution (developed under the National Science Foundation's support) as well as the more specialized features on the museum's website. These links make it easier to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. In particular there are hyperlinks to John Endler's research with Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life on Earth has produced a diversity of plants, animals, and insects. Paleobiology is the study of these creatures within their geographical context and offers a number of advantages over the current observational and experimental methods for 에볼루션코리아 analyzing evolutionary processes. In addition to examining the processes and events that happen regularly or over a lengthy period of time, paleobiology can be used to examine the relative abundance of various groups of organisms and their distribution in space over the course of geological time.

The Web site is divided into various paths to learning evolution, including "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 path also examines myths regarding evolution, and also the history of evolutionary thought.

Each of the main sections on the Evolution website is equally well-developed, and includes materials that are suited to a variety of educational levels and teaching styles. In addition to general textual content, the site features an array of multimedia and interactive content like videos, animations, and virtual labs. The content is presented in a nested bread crumb fashion that aids navigation and orientation within the large Web site.

The page "Coral Reef Connections", for example, provides a comprehensive overview of the coral's relationships, their interaction with other organisms, and then zooms in on a single clam, which is able to communicate with its neighbors and react to changes in the water conditions that occur on the reef level. This page, as well as the other multidisciplinary interactive and multimedia pages, gives a good introduction to the many areas of evolutionary biology. The material also provides a discussion of the role of natural selection as well as the concept of phylogenetic analysis, which is a key method to understand evolutionary change.

Evolutionary Theory

For biology students evolution is a crucial thread that weaves together all the branches of the field. A vast collection of books helps in teaching evolution across all disciplines of life science.

One resource, the companion to PBS's television show Understanding Evolution is an excellent example of a Web site that provides depth as well as breadth in terms of its educational resources. The site features a wide range of interactive learning modules. It also has a "bread crumb structure" that allows students to move away from the cartoon style that is used in 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 links to a page that highlights John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.

Another resource that is worth mentioning is the Evolution Library on this web site, which has an extensive collection of multimedia items that are related to evolution. The content is organized into curricula-based pathways that correspond to the learning objectives outlined in the standards for biology. It includes seven short videos specifically designed for use in classrooms. These can be streamed or purchased as DVDs.

A variety of crucial questions remain in the midst of evolutionary biology, 에볼루션카지노 such as the factors that trigger evolution and how fast it happens. This is particularly applicable to human evolution which has made it difficult to reconcile the notion that the physical characteristics of humans were derived from apes, 에볼루션 코리아카지노 - Scdmtj.Com, and the religions that believe that humanity is unique in the universe and has an enviable place in creation, with soul.

Additionally there are a myriad of ways that evolution could occur and natural selection is the most widely accepted theory. Scientists also study other kinds such as mutation, genetic drift, and sexual selection.

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