Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misconceptions about evolution remain. People who have been exposed to popular science myths often assume that biologists are saying they don't believe in evolution.

This rich website - companion to the PBS series offers teachers with resources that support evolution education and help avoid the kinds of misinformation that can make it difficult to understand. It's laid out in a "bread crumb" format to aid in navigation and orientation.

Definitions

It's difficult to teach evolution well. People who are not scientists often have a difficult time understanding the subject and some scientists employ a definition that confuses it. This is especially true when it comes to debates about the nature of the word.

It is therefore important to define the terms that are used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a simple and efficient manner. The website is a companion to the show that premiered in 2001, but it can also function as an independent resource. The content is presented in a nested fashion which aids navigation and orientation.

The site defines terms like common ancestor and gradual process. These terms help frame the nature of evolution as well as its relationship to other concepts in science. The site also provides an overview of how the concept of evolution has been researched and verified. This information can be used to dispel myths that have been engendered by the creationists.

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

Adaptation is the tendency of heritable traits to become better suited to an environment. This is the result of natural selection, which happens when organisms that have more adaptable traits are more likely to survive and reproduce than those with less adaptable traits.

Common ancestor: 에볼루션 무료 바카라 The latest common ancestor of two or more species. The common ancestor can be identified through analyzing the DNA of those species.

Deoxyribonucleic acid: A massive biological molecule that holds the information necessary for cell replication. The information is stored in nucleotide sequences that are strung into long chains known as chromosomes. Mutations are the basis for new genetic information in cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are influenced by evolutionary changes in the other. Coevolution is evident in the interaction of predator and prey, or parasites and hosts.

Origins

Species (groups that can crossbreed), evolve through a series natural changes in their offspring's traits. The causes of these changes are many factors, such as natural selection, gene drift and mixing of the gene pool. The evolution of a new species may take thousands of years, and the process could be slowed down or accelerated due to environmental conditions, such as climate change or the competition for food or habitat.

The Evolution site traces through time the evolution of different animal and plant groups, focusing on major transitions in each group's past. It also examines the human evolutionary roots and humans, a subject that is especially important for students to know.

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 bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap, which was first published in 1858, which was a year following the initial edition of The Origin.

The site is mostly an online biology resource, but it also contains lots of information about geology and paleontology. One of the most appealing features on the site are a timeline of events that show how geological and climatic conditions changed over time, as well as an interactive map of the distribution of some of the fossil groups featured on the site.

Although the site is a companion piece to a PBS television show however, it can stand on its own as a great source for teachers and students. The site is extremely well-organized and offers clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more specialized elements of the museum's web site. These links make it easier to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. Particularly, there are links to John Endler's experiments with Guppies, which demonstrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has led to a variety of plants, animals and insects. Paleobiology is the study of these creatures within their natural environment, has many advantages over modern observational or research methods for studying evolutionary processes. Paleobiology can examine not only the process and events that occur frequently or over time, but also the distribution and frequency of different species of animals in space over the course of geological time.

The site is divided into several optional ways to learn about evolution which include "Evolution 101," which takes the user on a linear path through the science of nature and the evidence supporting the theory of evolution. The course also focuses on misconceptions about evolution and also the history of evolutionary thought.

Each of the main sections on the Evolution website is equally well-developed, with materials that can be used to support a variety of educational levels and teaching styles. The site offers a wide array of interactive and multimedia content, including animations, video clips and virtual labs in addition to general textual content. The breadcrumb-like organization of the content helps with navigation and orientation on the massive website.

For instance, 에볼루션 the page "Coral Reef Connections" provides an overview of the relationships between corals and their interactions with other organisms. Then, it zooms in on a single clam that is able to communicate with its neighbors and respond to changes in the water conditions that take place at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to the broad variety of topics in evolutionary biology. The material also provides a discussion of the role of natural selection and the concept of phylogenetic analysis which is an important tool in understanding evolutionary changes.

Evolutionary Theory

For biology students evolution is a crucial thread that weaves together all branches of the field. A vast collection of resources can help teachers teach about evolution across the life sciences.

One resource, which is a companion to the PBS television series Understanding Evolution, 에볼루션 바카라사이트 is an excellent example of a Web site that provides the depth and 에볼루션 슬롯 breadth of its educational resources. The site offers a range of interactive learning modules. It also features a "bread crumb structure" that assists students in moving away from the cartoon style of Understanding Evolution and onto elements on this site that are more closely related to the worlds of research science. For example an animation that explains the concept of genetic inheritance links to a page highlighting John Endler's experiments in artificial selection with guppies in native ponds of Trinidad.

The Evolution Library on this website has a huge multimedia library of assets related to evolution. The content is organized into curricula-based pathways that correspond to the learning goals established in the biology standards. It includes seven short videos that are designed for use in classrooms. These are available to stream or purchase as DVDs.

A variety of crucial questions remain in the midst of evolutionary biology, including the factors that trigger evolution and the speed at which it occurs. This is particularly true for 에볼루션 the evolution of humans, where it was difficult to reconcile religious beliefs that held that humans have a distinct position in the universe and a soul, with the notion that our physical traits evolved from apes.

In addition there are a variety of ways that evolution can occur with natural selection being the most widely accepted theory. However scientists also study different types of evolution such as mutation, genetic drift and sexual selection, among others.

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