What Is Evolution Site? To Make Use Of It

Evolution Site - Teaching About Evolution

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

This site, which is a companion to the PBS series It provides teachers with materials that promote evolution education and avoid the kinds of myths that undermine it. It's arranged in a nested "bread crumb" format to facilitate navigation and orientation.

Definitions

It's not easy to teach evolution well. It is often misunderstood by non-scientists and even scientists use a definition that confuses the issue. This is especially true when it comes to discussions about the definition of the word itself.

Therefore, it is crucial to define the terms used in evolutionary biology. Understanding Evolution's website provides this in an easy and helpful way. The website is a companion to the show that premiered in 2001, but it is also an independent resource. The content is presented in a nested fashion that aids navigation and orientation.

The site defines terms like common ancestor and gradual process.  에볼루션  help to define the nature and significance of evolution with other scientific concepts. The site gives a comprehensive overview of the manner that evolution has been tested. This information can be used to dispel the myths that have been created by creationists.

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

The process of adaptation is the tendency of heritable traits to be more suitable to their environment. This is due to natural selection. It occurs when organisms that are more adaptable traits are more likely survive and reproduce than those with less adaptable characteristics.

Common ancestor (also called common ancestor): The most recent ancestral ancestor shared by two or more species. By studying the DNA of these species, it is possible to identify the common ancestor.

Deoxyribonucleic acid: A huge biological molecule that holds the information necessary for cell replication. The information is contained in sequences of nucleotides that are strung together into long chains, referred to as chromosomes. Mutations are the cause of new genetic information within cells.

Coevolution: A relationship between two species in which evolutionary changes in one species are affected by changes in evolutionary processes in the other. Examples of coevolution include the interactions between predator and prey or host and parasite.

Origins

Species (groups of individuals that can interbreed) change through a series of natural changes in the traits of their offspring. The changes can be triggered by a variety of causes, including natural selection, genetic drift, and mixing of genes. The evolution of new species could take thousands of years. Environmental conditions, such as climate changes or competition for food or habitat can impede or accelerate the process.

The Evolution site traces the emergence of various animal and plant groups through time with a focus on the key transitions that occurred in each group's history. It also examines the evolution of humans as a subject that is of particular interest to students.

When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been found. Among them was the famous skullcap and the associated bones discovered in 1856 in the Little Feldhofer Grotto in Germany that is now thought to be an early Homo neanderthalensis. While the skullcap wasn't published until 1858, just one 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 also offers a lot of information about geology as well as paleontology. The most impressive features of the website are a set of timelines which show how climatic and geological conditions changed over time, and an outline of the distribution of some of the fossil groups featured on the site.

The site is a companion for a PBS TV series but it could also be used as an educational resource by teachers and students. The site is well-organized, and provides clear links to the introduction material of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specific features of the museum website.  에볼루션 바카라 무료체험  make it easy to move from the cartoon-style Understanding Evolution pages into the more sophisticated worlds of research science. There are also links to John Endler's experiments with guppies, which illustrate the importance of ecology in evolutionary theory.

Diversity

The evolution of life has produced an array of animals, plants and insects. Paleobiology is the study of these creatures in their geographical context and offers many advantages over modern observational and experimental methods for analyzing evolutionary phenomena. In addition to exploring processes and events that occur frequently or over a long period of time, paleobiology allows to examine the relative abundance of various kinds of organisms as well as their distribution in space over geological time.

The site is divided into various paths to learning evolution which include "Evolution 101," which takes the viewer on a line through the nature of science and the evidence to support the theory of evolution. The course also focuses on misconceptions regarding evolution, and also the history of evolutionary thinking.

Each of the other major sections of the Evolution site is equally well constructed, with materials that support a variety of educational levels and pedagogical styles. In addition to the general textual content, the site offers a wide range of multimedia and interactive content like video clips, animations, and virtual labs. The breadcrumb-like arrangement of the content helps with navigation and orientation on the large website.

For example, the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interaction with other organisms. Then, it zooms in on a single clam that can communicate with its neighbours and respond to changes in water conditions 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 material also provides an explanation of the role of natural selection and the concept of phylogenetic analysis which is a crucial tool for understanding the evolution of change.

Evolutionary Theory

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

One resource, which is a companion to the PBS television series Understanding Evolution, is an exceptional 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 encased "bread crumb" structure that allows students to transition from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. For example an animation that introduces the notion of genetic inheritance leads to a page highlighting John Endler's experiments with artificial selection with guppies from the native ponds of Trinidad.

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

Evolutionary biology is still an area of study that poses many important questions, such as what triggers evolution and how fast it occurs. This is particularly true for human evolution, which has made it difficult to reconcile the notion that the physical characteristics of humans derived from apes, and the religions that believe that humanity is unique in the universe and has an enviable place in creation, with a soul.

In addition, there are a number of ways that evolution could occur, with natural selection being the most popular theory. However scientists also study other kinds of evolution, such as genetic drift, mutation, and sexual selection, among other things.

While many scientific fields of inquiry are in conflict with the literal interpretations of religious texts Evolutionary biology has been the subject of particularly fierce debate and opposition from religious fundamentalists. While some religions have been able to reconcile their beliefs with the ideas of evolution, others haven't.
