Find out the background of influenza virus classification, subtypes, and strains. Varieties of Influenza Influenza is an extremely variable, fast-mutating virus. There are three main types, or genera: Influenzavirus A, Influenzavirus B, and Influenzavirus C....http://www.brighthub.com/science/medical/articles/9082.aspxWed, 01 Oct 2008 03:37:57 GMTb133e95a-c263-4882-8f2a-b24547eff78e:9082ginkgo100How is phylogeny related to genealogy? Both study family relationships. Read about concepts relating to phylogeny. What is Phylogeny? Phylogeny is the evolutionary history of an organism. The great 19th century naturalist Ernst Haeckel coined the word phylogeny . It comes from Greek words roughly meaning "birth of races." Phylogen...http://www.brighthub.com/science/medical/articles/9115.aspxMon, 29 Sep 2008 19:32:41 GMTb133e95a-c263-4882-8f2a-b24547eff78e:9115ginkgo100Fungi phylogeny provides a good way to define this diverse group, whose members range from simple to complex. Since Carolus Linnaeus developed the system of biological classification we still use today, biologists have struggled to develop a good working definition of fungi. Fungi were not even placed into their own kingdom until the twentieth cent...http://www.brighthub.com/science/medical/articles/8880.aspxSun, 28 Sep 2008 16:35:52 GMTb133e95a-c263-4882-8f2a-b24547eff78e:8880ginkgo100Phylogeny is not just theoretical science. Researchers in applied fields from medicine to environmental clean-up have found the study of phylogeny to be valuable. Phylogeny is the evolutionary history of a characteristic, individual, population, species, or group of species. It is most often depicted as a branching tree analogous to a family tree. ...http://www.brighthub.com/science/medical/articles/8071.aspxTue, 23 Sep 2008 18:30:19 GMTb133e95a-c263-4882-8f2a-b24547eff78e:8071ginkgo100Mikko's Phylogeny Archive is a project aimed at collecting phylogeny trees to represent all living organisms. Though it is a private, non-scholarly project, this remarkable project is still a respected and valuable source for phylogeny information. Finnish paleontology student Mikko Haaramo began Mikko's Phylogeny Archive ( http://www.helsinki....http://www.brighthub.com/science/medical/articles/8069.aspxTue, 23 Sep 2008 02:22:39 GMTb133e95a-c263-4882-8f2a-b24547eff78e:8069ginkgo100The theory of recapitulation in its strict literal form is now known to have many problems, but it had a notable influence on other areas of science such as the social sciences. Part Two of this series explores these ideas. Problems with the Haeckel model If Haeckel's model, as described in Part One, were literally true, it would make the study of ...http://www.brighthub.com/science/medical/articles/8067.aspxTue, 23 Sep 2008 01:26:53 GMTb133e95a-c263-4882-8f2a-b24547eff78e:8067ginkgo100"Ontology recapitulates phylogeny" is a phrase signifying a relatively old idea in biology. Based on observations of embryos, its meaning and importance have changed through the history of science. Part One of this series examines the origin of this idea. The phrase "ontogeny recapitulates phylogeny," sometimes called simply the t...http://www.brighthub.com/science/medical/articles/8060.aspxTue, 23 Sep 2008 00:54:35 GMTb133e95a-c263-4882-8f2a-b24547eff78e:8060ginkgo100The phrase "ontogeny recapitulates phylogeny" still has some value in modern zoology, even though its original version has been thoroughly rejected. Part Three of this series explains its importance to cladistics. The modern theory of evolution differs enormously from Lamarckian evolution. For example, traits are now known to be inherited s...http://www.brighthub.com/science/medical/articles/7274.aspxMon, 15 Sep 2008 16:43:42 GMTb133e95a-c263-4882-8f2a-b24547eff78e:7274ginkgo100This article is the second in a two-part series on shark phylogeny. It describes the evolutionary relationships between different groups of sharks and includes a shark phylogeny tree in text form. Introduction to Shark Phylogeny Sharks and rays are known as elasmobranchs (subclass Elasmobranchii), and they share a common ancestor separate from that...http://www.brighthub.com/science/medical/articles/4831.aspxThu, 11 Sep 2008 17:42:48 GMTb133e95a-c263-4882-8f2a-b24547eff78e:4831ginkgo100Do any scientists believe that humans evolved from apes? The answer may surprise you. In the creation vs. evolution debate, you will not find a single scientist who believes in ape to human evolution. This fact may seem startling to many observers who are curious about human origins. The truth is that both sides agree on this point -- but they ...http://www.brighthub.com/science/medical/articles/4522.aspxFri, 15 Aug 2008 07:00:46 GMTb133e95a-c263-4882-8f2a-b24547eff78e:4522ginkgo100In the creation vs. evolution debate, this is a big question. To understand the answer, it is important first to understand what the term "theory" means in science. Evolutionary biologists say that evolution is both a fact and a theory. What is a theory? In the creation vs. evolution debate, proponents of Biblical Creationism often asse...http://www.brighthub.com/science/medical/articles/3134.aspxFri, 25 Jul 2008 14:23:46 GMTb133e95a-c263-4882-8f2a-b24547eff78e:3134ginkgo100Cladistic analysis allows biologists to trace evolutionary relationships among organisms by analyzing their characteristics. Sequence analysis made it possible to apply bioinformatics techniques to cladistics and has led to extraordinary discoveries about the history of life on earth. All about Cladistics and Cladograms Cladistics is the field of s...
