Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, there are still a lot of misconceptions about evolution. People who have taken in the nonsense of pop science often believe that biologists are saying they don't believe in evolution.

This rich Web site - companion to the PBS series offers teachers with resources that support evolution education and help avoid the kinds of myths that hinder it. It's arranged in a nested "bread crumb" format for ease of navigation and orientation.

Definitions

It is difficult to teach evolution well. It is often misunderstood even by non-scientists, and even scientists have been guilty of using definitions that confuse the issue. This is especially 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 way. The site is a companion to the series that first aired in 2001, but it can also function as an independent resource. The content is presented in a nested manner that aids navigation and orientation.

The site defines terms like common ancestor and gradual process. These terms help to define the nature and relationship of evolution to other concepts in science. The site provides an overview of the way in which evolution has been tested. This information can help dispel the myths created by 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 suited to the environment. This is the result of natural selection, 무료 에볼루션 which happens when organisms that have better-adapted traits are more likely to survive and reproduce than those with less adaptable characteristics.

Common ancestor (also known as common ancestor): The most recent ancestor shared by two or more species. The common ancestor can be identified by analyzing the DNA of the species.

Deoxyribonucleic acid: A massive biological molecule that holds the information necessary for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, called chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is the relationship between two species, where the evolutionary changes of one species influence evolutionary changes of the other. Coevolution can be seen in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups that can crossbreed) change 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 development of new species can take thousands of years. Environmental conditions, like climate change or competition for food resources and habitat can slow or speed up the process.

The Evolution site traces through time the emergence of various species of plants and animals and focuses on major changes in each group's past. It also focuses on the evolutionary origin of humans which is crucial for students to know.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The most famous among them was the skullcap and associated bones found in 1856 in the Little Feldhofer Grotto in Germany that is now thought as an early Homo neanderthalensis. It is unlikely that Darwin knew about the skullcap when it was published in 1858, one year after the first edition of The Origin.

The site is primarily a biology site however it also includes lots of information about geology and paleontology. The website has several features that are particularly impressive, including the timeline of the way that climate and geological conditions have changed over the course of time. It also includes a map showing the distribution of fossil groups.

Although the site is a companion to a PBS television show but it also stands on its own as an excellent source for teachers and students. The site is well-organized and offers clear links to the introduction information of Understanding Evolution (developed under the National Science Foundation's funding) and the more specific features on the museum's website. These links facilitate the transition from the enthralling cartoon style of the Understanding Evolution pages to the more sophisticated world 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 led to many species of plants, animals and insects. Paleobiology, the study of these creatures in their geological environment, has many advantages over modern observational or research methods for exploring evolutionary processes. In addition to examining processes and events that take place regularly or over a lengthy period of time, paleobiology can be used to analyze the diversity of species of organisms and their distribution across geological time.

The site is divided into various pathways to understanding evolution which include "Evolution 101," which takes the viewer on a liner 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 history of evolutionary thought.

Each of the other main sections of the Evolution site is similarly developed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. In addition to the standard textual content, the site also has an array of multimedia and interactive resources, such as videos, animations, and virtual labs. The content is organized 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, it gives a brief overview of the coral's relationships, their interaction with other organisms and then is enlarged to show a single clam, which is able to communicate with its neighbors and respond to changes in the conditions of the water at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages, provides an excellent introduction to the many areas of evolutionary biology. The information also includes an overview of the importance of natural selection as well as the concept of phylogenetic analysis which is an important method to understand 에볼루션 바카라사이트 evolutionary change.

Evolutionary Theory

For biology students the concept of evolution is a major thread that binds all branches of the field. A vast collection of books helps in teaching evolution across the disciplines of life sciences.

One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that provides depth and a variety of educational resources. The site features a wide range of interactive learning modules. It also has an "bread crumb structure" that allows students to move away from the cartoon-like style used in Understanding Evolution and onto elements of this vast website that are closely connected to the realms of research science. An animation that introduces the concept of genetics is linked to a page about John Endler's experiments with artificial selection using guppies on native ponds in Trinidad.

Another useful resource is the Evolution Library on this website, which includes an extensive collection of multimedia assets that are related to evolution. The content is organized according to curriculum-based paths that parallel the learning objectives set out in the standards for biology. It includes seven short videos specifically designed for use in classrooms, 에볼루션 바카라 무료카지노; Http://th.sign-in-thai.com/gourl/index.php?url=evolutionkr.kr/, and can be streamed at no cost or purchased on DVD.

Many important questions remain at the core of evolutionary biology, such as what causes evolution to occur and the speed at which it occurs. This is particularly applicable to human evolution where it has been difficult to reconcile that the innate physical characteristics of humans evolved from apes and religious beliefs that claim that humanity is unique in the universe and has an exclusive place in the creation, with soul.

There are a myriad of other ways in which evolution could occur, with natural selection as the most popular theory. Scientists also study different types like mutation, genetic drift and sexual selection.

While many scientific fields of study conflict with literal interpretations found in religious texts, the concept of evolution biology has been a source of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs to evolution while others haven't.
