Evolution Site - Teaching About Evolution

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

This rich Web site, which is a complement to the PBS program, provides teachers with materials which support evolution education while avoiding the types of misconceptions that can make it difficult to understand. It's laid out in a "bread crumb" format to facilitate navigation and orientation.

Definitions

Evolution is a complicated and difficult subject to teach effectively. It is often misunderstood even by non-scientists, and even some scientists use a definition that confuses the issue. This is especially applicable to discussions on the nature of the word.

It is therefore crucial to define the terms used in evolutionary biology. Understanding Evolution's website helps you define these terms in an easy and helpful manner. It is an accompanying site for the 2001 series, and it is also a resource on its own. The information is presented in a structured manner that makes it simpler to navigate and understand.

The site defines terms such as common ancestor and gradual process. These terms help define the nature and relationship of evolution to other concepts in science. The site gives a comprehensive overview of the way the concept of evolution has been examined. This information can help dispel myths created by creationists.

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

Adaptation is the process of changing hereditary traits to become more suitable to their environment. This is a result of natural selection, 에볼루션사이트 which happens when organisms that have better adapted traits are more likely to survive and reproduce than those with less adaptable characteristics.

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

Deoxyribonucleic acid: 에볼루션 코리아 A massive biological molecule that contains information needed for cell replication. The information is stored in nucleotide sequences, which are strung into long chains known as chromosomes. Mutations are the reason behind the creation of new genetic information within cells.

Coevolution is a relation between two species, where the evolution of one species influence evolutionary changes in the other. Examples of coevolution include the interactions between predator and prey or 에볼루션 바카라 사이트 무료 바카라; evolutionblackjack03281.Azzablog.Com, host and parasite.

Origins

Species (groups that can interbreed) develop by a series of natural variations in their offspring's traits. These changes are caused by a variety of causes, including natural selection, genetic drift and mixing of gene pools. The evolution of new species can take thousands of years. Environmental conditions, such as climate change or competition for food or habitat can slow or speed up the process.

The Evolution site tracks the evolution of a variety of groups of animals and plants over time and focuses on the most significant shifts that occurred throughout the history of each group. It also focuses on human evolution as a subject of particular importance to students.

Darwin's Origin was written in 1859, when only a handful of antediluvian fossils of humans had been found. The most famous among them was the skullcap and bones that were discovered in 1856 in the Little Feldhofer Grotto in Germany, which is now known to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, which was a year before the first edition of the Origin was published, it is extremely 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 series of timelines that show how climatic and geological conditions have changed over time and a map of the geographical distribution of some fossil groups that are featured on the site.

The site is a companion for the PBS TV series but it could also be used as a resource by teachers and students. The site is extremely well organized and provides clear links between the introduction information in Understanding Evolution (developed with support from the National Science Foundation) and the more sophisticated elements of the museum's web site. These hyperlinks make it easy to move from the cartoon style of Understanding Evolution pages into the more sophisticated worlds of research science. There are also links to John Endler's experiments with guppies. They illustrate the importance ecology in evolutionary theory.

Diversity

The evolution of life on Earth has resulted in a variety of animals, plants, and insects. Paleobiology is the study of these creatures in their natural environment and has many advantages over the current observational and experimental methods for analyzing evolutionary phenomena. Paleobiology is able to study not only the process and events that take place regularly or over time but also the relative abundance and distribution of various animal groups in space over the course of geological time.

The website is divided into various paths to learning evolution that include "Evolution 101," which takes the viewer on a liner path through the nature of science and the evidence supporting the theory of evolution. The path also reveals common misconceptions about evolution and the history of evolutionary thought.

Each of the other major sections of the Evolution site is equally well created, with resources that support a variety of curriculum levels and pedagogical styles. In addition to the general textual content, the site offers an array of interactive and multimedia resources including videos, animations and virtual labs. The content is laid out in a nested bread crumb style that facilitates navigation and orientation on the web site.

The page "Coral Reef Connections", for example, 에볼루션 카지노 provides a comprehensive overview of the coral's relationships, their interaction with other organisms, and then zooms in on a single clam, which can communicate with its neighbors and react to changes in conditions of the water at the reef level. This page, along with the other multidisciplinary interactive and multimedia pages provides an excellent introduction to a variety of topics in evolutionary biology. The material includes a discussion on the importance of natural selection and the concept of phylogenetics analysis as a key tool to understand evolutionary changes.

Evolutionary Theory

For biology students, evolution is a key thread that connects all the branches of the field. A wide range of resources supports teaching about evolution across the life sciences.

One resource, the companion to PBS's television series Understanding Evolution is an excellent example of an Web page that offers both depth as well as wide range of educational resources. The site has a wide array of interactive learning modules. It also has an embedded "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this massive website that are more closely tied to the field of research science. An animation that introduces the concept of genetics links to a page that highlights John Endler's artificial-selection experiments with guppies on native ponds in Trinidad.

Another resource that is worth mentioning is the Evolution Library on this site, which has an extensive multimedia library of resources related to evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives outlined in the biology standards. It contains seven videos specifically designed for use in the classroom, and can be streamed at no cost or purchased on DVD.

Evolutionary biology is a field of study with a lot of important questions to answer, such as the causes of evolution and the speed at which it happens. This is especially true for humans' evolution, where it was difficult to reconcile religious beliefs that held that humanity has a special place in creation and a soul with the notion that our physical traits were derived from the apes.

There are also a number of other ways evolution can take place, with natural selection as the most popular theory. Scientists also study different types like mutation, genetic drift and sexual selection.

Many fields of inquiry have a conflict with the literal interpretations of religious texts evolutionary biology has been the subject of particularly intense controversy and resistance from religious fundamentalists. While certain religions have been able to reconcile their beliefs with the ideas of evolution, other religions haven't.
