A Step-By-Step Guide To Evolution Site From Start To Finish
Evolution Site - Teaching About Evolution
Despite the best efforts of biology educators, misconceptions about evolution persist. Pop science fiction has led a lot of people to believe that biologists don't believe evolution.
This rich Web site, which is a companion to the PBS program offers teachers resources that promote evolution education, while avoiding the kinds of misconceptions which hinder it. It's laid out in the "bread crumb" format to facilitate navigation and orientation.
Definitions
Evolution is a complicated and difficult subject to teach well. It is often misunderstood even by non-scientists, and even scientists are guilty of using definitions that confuse the issue. This is especially true when it comes to discussions about the nature of the word.
It is therefore important to define the terms 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 which first aired in 2001, but also functions as an independent resource. The material is presented in a way which aids navigation and orientation.
The site defines terms such as common ancestor (or common ancestor), gradual process, and adaptation. These terms help frame the nature and significance of evolution to other scientific concepts. The site also provides an overview of how the concept of evolution has been vetted and confirmed. This information can help dispel the myths that are created by the creationists.
It is also possible to get a glossary of terms used in evolutionary biology. These terms include:
Adaptation: The tendency for 에볼루션 룰렛 heritable traits to become better suited to a particular environment. This is a result of natural selection. Organisms with better-adapted traits are more likely than those with less-adapted traits to survive and reproduce.
Common ancestor: The latest common ancestor of two or more different species. The common ancestor 에볼루션 바카라 체험 코리아 (118.89.58.19) can be identified through analyzing the DNA of those species.
Deoxyribonucleic Acid: A huge biological molecular that contains the necessary information for cell replication. The information is contained in a sequence of nucleotides that are strung together to form long chains, also known as chromosomes. Mutations are responsible for the creation of new genetic information inside cells.
Coevolution is a relationship between two species where evolutionary changes in one species are dependent on evolutionary changes in the other. Examples of coevolution include the interaction between predator and prey, or host and parasite.
Origins
Species (groups that can crossbreed), evolve through a series natural changes in their offspring's traits. These changes can be caused by 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 changes or competition for food resources and habitat can impede or accelerate the process.
The Evolution site tracks through time the emergence of various animal and plant groups, focusing on major transitions in each group's history. It also focuses on human evolution, which is a topic that is of particular interest for students.
When Darwin wrote the Origin, only a handful of antediluvian human fossils had been discovered. One of them was the infamous 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. Although the skullcap was not published until 1858, just a year before the first edition of the Origin was published, it's extremely unlikely that Darwin had ever heard of it.
While the site is focused on biology, it includes a good deal of information on geology and paleontology. The most impressive features of the website are a series of timelines that show how climatic and 에볼루션 룰렛 geological conditions changed over time, as well as an outline of the distribution of a few of the fossil groups featured on the site.
The site is a companion to a PBS television series, but it can also be used as a resource by teachers and students. The site is well-organized, and provides clear links to the introduction content of Understanding Evolution (developed under the National Science Foundation's assistance) and the more specialized features on the museum's website. These hyperlinks make it easy to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. Particularly there are links to John Endler's experiments using Guppies that demonstrate the importance of 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 geological context offers many advantages over modern observational or research methods for exploring evolutionary processes. In addition to exploring processes and events that occur frequently or over a long period of time, paleobiology allows to analyze the relative abundance of different groups of organisms and their distribution across the geological time.
The site is divided into various routes that can be taken to gain knowledge about evolution. One of these paths, "Evolution 101," guides the user through the evolution of nature and the evidence of evolution. The path also examines myths regarding evolution, and the background of evolutionary thought.
Each of the main sections of the Evolution website is equally well-developed, with materials that are suited to a variety of levels of curriculum and teaching methods. In addition to the standard textual content, the site offers an array of interactive and multimedia resources, such as videos, animations and virtual laboratories. The breadcrumb-like arrangement of the content assists with navigation and orientation on the massive web site.
The page "Coral Reef Connections" For instance, the page "Coral Reef Connections" gives a brief overview of coral relationships, their interaction with other organisms, and then zooms in on one clam that can communicate with its neighbors and respond to changes in the conditions of the water that occur at the reef level. This page, along with the other multidisciplinary, multimedia, and interactive pages on the site, provide an excellent introduction to a broad range of topics in evolutionary biology. The information also includes an explanation of the role of natural selection and the concept of phylogenetic analysis which is a key tool in understanding evolutionary change.
Evolutionary Theory
Evolution is an underlying thread that runs through all branches of biology. A wide range of resources helps teachers teach about evolution across the life sciences.
One resource, a companion to the PBS television series Understanding Evolution, is an outstanding example of an Web site that offers both depth and a variety of educational resources. The site offers a variety of interactive learning modules. It also has an embedded "bread crumb" structure that helps students move from the cartoon style of Understanding Evolution to elements on this large Web site more closely tied to the field of research science. Animation that introduces the concept of genetics is linked to a page that highlights John Endler's experiments with artificial selection using Guppies living in ponds native to Trinidad.
The Evolution Library on this website is a vast multimedia library of materials that deal with evolution. The contents are organized into curricula-based pathways that correspond to the learning objectives set out in the standards for biology. It contains seven videos designed specifically for classroom use, which can be streamed at no cost or purchased on DVD.
Evolutionary biology remains an area of study that poses many important questions to answer, such as what triggers evolution and how quickly it happens. This is especially true for human evolution, where it's been difficult to reconcile the notion that the physical characteristics of humans derived from apes, and the religious beliefs that claim that humans are unique in the universe and 에볼루션 바카라 무료 has an exclusive place in the creation, with soul.
There are a myriad of other ways in which evolution can take place including natural selection, which is the most widely accepted theory. However, scientists also study other kinds of evolution like mutation, genetic drift, and sexual selection, among others.
While many scientific fields of study are in conflict with literal interpretations found in religious texts, the concept of evolution biology has been a subject of intense controversy and opposition from religious fundamentalists. Some religions have reconciled their beliefs with evolution, while others haven't.
