Why Evolution Site Is Your Next Big Obsession

Evolution Site - Teaching About Evolution

Despite the best efforts of biology educators, misinformation about evolution remain. People who have absorbed pop science nonsense often assume that biologists are saying they don't believe in evolution.

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

Definitions

It's difficult to effectively teach evolution. Many non-scientists are unable to grasp the concept, and some scientists even employ a definition that confuses it. This is particularly relevant when discussing the definition of the words.

It is therefore important to define the terms used in evolutionary biology. Understanding Evolution's website provides this in a simple and efficient way. The site serves as an accompaniment to the 2001 series, but also a resource on its own. The content is presented in a structured manner that makes it easier to navigate and comprehend.

The site defines terms such as common ancestor, gradual process and so on. These terms help define the nature and significance of evolution with other scientific concepts. The site gives a comprehensive overview of the manner in which evolution has been tested. This information can help dispel myths created by creationists.

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

Adaptation is the process of changing heritable traits to be better suited to an environment. This is due to natural selection, which happens when organisms with more adaptable characteristics are more likely to survive and reproduce than those with less adapted characteristics.

Common ancestor: 에볼루션 무료체험 The most recent common ancestor of two or more different species. By analyzing the DNA from these species it is possible to determine the common ancestor.

Deoxyribonucleic Acid: A large biological molecular that contains the information needed for cell replication. The information is stored in nucleotide sequences which are strung into long chains known as chromosomes. Mutations are the cause of new genetic information in cells.

Coevolution is a relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution can be seen in the interaction of predator and prey, or parasite and hosts.

Origins

Species (groups of individuals that can interbreed) develop through an array of natural changes in the traits of their offspring. Changes can be caused by numerous factors, like natural selection, gene drift and 무료 에볼루션 바카라 체험 (look here) mixing of the gene pool. The development of new species can take thousands of years. Environmental conditions, such as changes in the climate or competition for food and habitat can slow or speed up the process.

The Evolution site tracks the evolution of a number of different animal and plant groups through time, focusing on the major transitions that occurred in each group's history. It also explores the human evolutionary roots which is especially important for students to know.

When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. The skullcap that is famous, along with the associated bones were discovered in 1856 in the Little Feldhofer Grotto of Germany. It is now regarded as an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap when it was published in 1858, one year following the initial edition of The Origin.

While the site is focused on biology, 에볼루션 사이트 it also offers a lot of information about geology and paleontology. The most impressive features of the website are a timeline of events that show how geological and 에볼루션 무료체험 climatic conditions have changed over time, as well as an interactive map of the distribution of a few of the fossil groups featured on the site.

Although the site is a companion piece to the PBS television show however, it can stand on its own as a valuable resource 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 specialized features of the museum website. These links facilitate the transition from the engaging 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, which 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 within their geological context, has many advantages over the current observational or experimental methods of studying evolutionary processes. In addition to studying processes and events that occur regularly or over a long period of time, paleobiology can be used to study the relative abundance of various species of organisms and their distribution throughout the course of geological time.

The site is divided up into different paths that can be chosen to gain knowledge about evolution. One of these paths, "Evolution 101," walks the reader through the evolution of nature and 에볼루션코리아 the evidence of evolution. The path also explores misconceptions about evolution and the background of evolutionary thought.

Each of the other main sections of the Evolution site is equally well created, with resources that can be used to support a range of different pedagogical levels and curriculum levels. The site includes a variety of interactive and multimedia resources which include animations, video clips and virtual labs as well as general textual content. The breadcrumb-like arrangement of the content aids in navigation and orientation on the vast website.

For instance the page "Coral Reef Connections" gives a brief overview of coral relationships and their interactions with other organisms. It then narrows down to a single clam that can communicate with its neighbours and respond to changes in water conditions that take place at the reef level. This page, along with the other multidisciplinary multimedia and interactive pages, gives a good introduction to the many areas of evolutionary biology. The content also includes an overview of the role of natural selectivity and the concept of phylogenetics as a key tool for understanding evolutionary change.

Evolutionary Theory

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

One resource, a companion to the PBS television series Understanding Evolution, is an exceptional example of a Web site that offers both depth and breadth in its 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 large Web site more closely linked to the world of research science. An animation that introduces students to the concept of genetics is linked to a page about John Endler's experiments in artificial selection using Guppies in native ponds in Trinidad.

The Evolution Library on this website has a huge multimedia library of resources that are associated to evolution. The content is organized in curriculum-based pathways that correspond to the learning objectives set out in the biology standards. It includes seven short videos specifically designed for classroom use, which can be streamed at no cost or purchased on DVD.

Many important questions remain at the core of evolutionary biology, such as the factors that trigger evolution and the speed at which it occurs. This is particularly relevant to human evolution, where it has been difficult to reconcile the notion that the physical characteristics of humans evolved from apes, and the religious beliefs that claim that humans are unique in the universe and has an exclusive place in the creation. It is soul.

There are a variety of other ways evolution can occur including natural selection, which is the most popular theory. Scientists also study other kinds such as genetic drift, and sexual selection.

Although many scientific fields of study have a conflict with literal interpretations found in religious texts, evolution biology has been a subject of intense debate and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, but others haven't.
