5 Evolution Site Projects For Any Budget
Evolution Site - Teaching About Evolution
Despite the best efforts by biology educators, there are still a lot of misconceptions regarding evolution. People who have taken in popular science myths often assume that biologists are saying they do not believe in evolution.
This rich website - companion to the PBS series - provides teachers with materials that promote evolution education and avoid the kinds of myths that make it difficult to understand. It's laid out in a "bread crumb" format to aid in navigation and orientation.
Definitions
Evolution is a complicated and difficult subject matter to teach 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 relevant to discussions about the nature of the word.
It is therefore essential to define the terms used in evolutionary biology. The website for the PBS show, Understanding Evolution, does this in a clear and useful way. The site is both a companion for the 2001 series, and also a resource on its own. The information is organized in a manner that makes it easier to navigate and comprehend.
The site defines terms like common ancestor and gradual process. These terms help to define the nature of evolution as well as its relation to other scientific concepts. The site gives a comprehensive overview of the way in which evolution has been tested. This information can help dispel the myths created by creationists.
You can also access a glossary that contains terms that are used in evolutionary biology. These terms include:
Adaptation: The tendency for heritable traits to become better suitable to a particular setting. This is the result of natural selection. Organisms that have better-adapted characteristics are more likely than those with less-adapted traits to survive and reproduce.
Common ancestor (also called common ancestor): 에볼루션 바카라 체험 슬롯, Recommended Looking at, The most recent ancestor that is shared by two or more species. By analyzing the DNA from these species it is possible to identify the common ancestor.
Deoxyribonucleic acid: A massive biological molecule that contains information necessary for cell replication. The information is stored in sequences of nucleotides that are strung together into long chains, also known as chromosomes. Mutations are the source of new genetic information in cells.
Coevolution is a relationship between two species where evolutionary changes in one species are affected by changes in evolutionary processes in the other. Coevolution is evident through the interaction between predator and prey, or parasite and hosts.
Origins
Species (groups of individuals that are able to interbreed) develop through a series of natural changes in the characteristics of their offspring. These changes are caused by a variety of causes, including natural selection, genetic drift and mixing of genes. The development of a new species may take thousands of years and the process may be slowed or increased by environmental conditions such as climate change or competition for food or habitat.
The Evolution site tracks the development of various groups of animals and plants over time and focuses on the most significant changes that took place in each group's history. It also examines the evolutionary history of humans which is especially important for students to know.
When Darwin wrote the Origin in 1859, only a handful of antediluvian human fossils had been discovered. One of them was the infamous skullcap and 바카라 무료 에볼루션 (one-time offer) bones that were discovered in 1856 at the Little Feldhofer Grotto in Germany which is now believed to be an early Homo neanderthalensis. It is highly unlikely that Darwin knew about the skullcap when it was published in 1858, which was a year after the publication of the first edition of The Origin. Origin.
While the site focuses on biology, it also includes a good deal of information about geology as well as paleontology. Among the best features of the website are a series of timelines that illustrate the way in which climatic and geological conditions changed over time, as well as a map of the distribution of a few of the fossil groups featured on the site.
While the site is a companion to the PBS television series but it also stands on its own as a valuable source for teachers and students. The site is well organized and provides clear links between the introductory material in Understanding Evolution (developed with support from the National Science Foundation) and the more specific elements of the museum Web site. These hyperlinks make it easy to move from the cartoon style of Understanding Evolution pages into the more sophisticated realms of research science. There are links to John Endler's experiments with guppies that illustrate the importance ecology in evolutionary theory.
Diversity
The evolution of life on Earth has produced a diversity of animals, plants, and insects. Paleobiology is the study of these creatures within their geological context and has numerous advantages over the modern observational and research methods in its exploration of evolutionary phenomena. Paleobiology can examine not just the processes and events that happen frequently or over time, but also the distribution and frequency of different species of animals in space throughout geological time.
The Web site is divided into various pathways to understanding evolution that include "Evolution 101," which takes the user on a linear path through the scientific process and the evidence to support the theory of evolution. The path also reveals common misconceptions about evolution as well as the history of evolutionary thought.
Each of the other sections of the Evolution site is similarly constructed, with materials that can be used to support a range of different pedagogical levels and curriculum levels. The site has a range of multimedia and interactive resources, including videos, animations, and virtual laboratories in addition to general textual content. The breadcrumb-like arrangement of the content assists with navigation and orientation on the massive Web site.
For instance, the page "Coral Reef Connections" provides a comprehensive overview of the relationships between corals and their interactions with other organisms. Then, it narrows down to a single clam that can communicate with its neighbors and react to changes in water conditions that occur at the reef level. This page, as well as the other multidisciplinary, multimedia, and interactive pages on the site, offer an excellent introduction to a wide variety of topics in evolutionary biology. The material includes an overview of the significance of natural selectivity and the concept phylogenetics analysis, an important tool for understanding evolutionary changes.
Evolutionary Theory
Evolution is an underlying thread that connects all branches of biology. A rich collection supports teaching evolution across the life science disciplines.
One resource, which is the companion to PBS's television series Understanding Evolution is an excellent example of an Web page that offers both depth and breadth in terms of its educational resources. The site offers a variety of interactive learning modules. It also features an "bread crumb structure" that assists students in moving away from the cartoon style used in Understanding Evolution and onto elements on this large website more closely linked to the fields of research science. For instance an animation that introduces the concept of genetic inheritance links to a page that highlights John Endler's artificial selection experiments with guppies from the native ponds of Trinidad.
The Evolution Library on this website contains a large multimedia library of materials that deal to evolution. The content is organized into curricula-based paths that correspond to the learning objectives outlined in the biology standards. It contains seven videos designed specifically for classroom use, which can be streamed for free or purchased on DVD.
Evolutionary biology is still an area of study that has many important questions, including what causes evolution and how fast it occurs. This is particularly true for the evolution of humans where it was a challenge to reconcile religious beliefs that humanity has a unique position in the universe and a soul with the notion that human beings have innate physical traits originated from Apes.
Additionally there are a myriad of ways in which evolution could be triggered, with natural selection being the most widely accepted theory. However, scientists also study other types of evolution such as genetic drift, mutation, and sexual selection, among others.
While many scientific fields of study have a conflict with the literal interpretations of religious texts, the concept of evolution biology has been the subject of intense debate and opposition from religious fundamentalists. While certain religions have managed to reconcile their beliefs with the notions of evolution, other religions haven't.
