Heather Driscoll, Botany & Mycology 2009 Poster Interviews Molecular phylogeny of the genus Costus (Costaceae). Co-authors: Irene T. Liao, Yizhuo Wang and Chelsea Specht The genus Costus (Costaceae) is a large group of perennial herbs distributed in the moist rainforests of both the New and Old World tropics with its center of species diversity in the neotropics. A genus-wide molecular phylogeny for Costus, including 84 ingroup taxa and two outgroup taxa (Monocostus uniflorus and Chamaecostus lanceolatus), was reconstructed to explore evolutionary trends in floral morphology, pollination biology, and biogeography of the group. The phylogenetic ***ysis is based on two nuclear ribosomal sequences — the internal and external transcribed spacers (ITS and ETS) —and the 23rd intron of the low copy nuclear gene RNA polymerase II (RPB2) from a taxonomically and geographically diverse sample. Parsimony and Bayesian phylogenetic ***yses of the combined data support a monophyletic Costus and corroborate recent hypotheses as to membership and sequence of origin of the major groups within the genus. Neotropical Costus represents a rapidly evolving, monophyletic group, which remains inadequately resolved, while African Costus form a paraphyletic group comprised of several early-diverging lineages each comprised of a few closely related species.

Nairi Hartooni - Botany 2010 Phylogenetic Relationships in the Genus Lewisia (Montiaceae), Inferred Using nrDNA (ITS, ETS) and cpDNA (rps16). Co-authors: C. Matt Guilliams and Bruce G. Baldwin The genus Lewisia comprises between 25 and 30 taxa of perennial flowering plants in the Montia family, or Montiaceae. This variable, western North American genus has been the subject of three recent monographic treatments, each of which has proposed slightly different infrageneric classifications. Molecular phylogenetic data have been lacking to resolve evolutionary relationships and evaluate these classifications, however. Here we examine evolutionary relationships in the genus Lewisia using DNA sequence data from the internal and external transcribed spacer regions of the nuclear genome as well as rps16 intron of the chloroplast genome. Sequence data have been obtained for nearly all recently recognized Lewisia taxa and for many outgroups in the Montiaceae, including Calandrinia, Calyptridium, Cistanthe, Claytonia, Lenzia, Lewisiopsis, Montia, Montiopsis, and Phemeranthus. Hypotheses of relationships in Lewisia resulting from phylogenetic ***yses are congruent with some elements of each of the previous classifications. Lewisia is recovered as a monophyletic group with strong support in all ***yses, and several clades within the genus are resolved. Increased taxon sampling within Lewisia and including additional DNA regions in ***yses are likely to improve phylogenetic understanding and allow for a more ...

Morphing Arachnids Using Phylogenies for Time Travel Each feature of the living species at the tips of a phylogenetic tree can be mapped onto the tree to determine where evolutionary changes likely occurred. Then, at each branching point (or internal node), the features can be blended together to form am overall picture of what the ancestral species may have looked like. In this video from the Peabody Museums Travels in the Great Tree of Life exhibit, the left hand side of the animation shows a phylogenetic tree of selected arachnids (spiders, scorpions, and their relatives); on the right hand side you can see an animation that shows what the ancestral species may have looked like at different points in the tree. Travels in the Great Tree of Life" was produced for the Yale Peabody Museum of Natural History with the support from the US National Science Foundation through the CIPRes and Angiosperm Tree of Life Programs.

Phylogenetic Approaches to the study of Vertebrate Classification, UCLA Dr. Michael Alfaro, Department of Ecology and Evolutionary Biology lecture from 10/28/2009
Christian Matthiessen -- Language evolving: Notes towards a semiotic history of humanity Webcast sponsored by the Irving K. Barber Learning Centre, and hosted by the Department of Language and Literacy Education and the Faculty of Education as part of the plenary session at the 37th International Systemic Functional Congress, Matthiessen poses the theme that is "language evolving". This can be interpreted either very generally or more technically. (1) Taken very generally, this could mean language changing in any of the three time-frames that have been explored in systemic functional linguistics phylogenetic change (language changing in the human species, or in human societies, over a long period of time ranging from generations to history of the human species), ontogenetic change (language changing in human individuals [seen as organisms or as persons] in the course of a lifetime, or logogenetic change (language changing in the course of the unfolding of text). (2) Taken more technically (ie with "evolution" in the technical sense introduced by Darwin), this means language changing phylogenetically language evolving as part of the evolution of the human species (in biological terms) and as part of the evolution of human groups (in social terms), these two being complementary aspects of human evolution. However, Matthiesson focuses on the narrower, technical sense of "language evolving". More specifically, he explores the "big history" of humans - a deep time view of human evolution in linguistic, or more generally in semiotic terms, starting with the ...
Phylogenetic Independent Contrasts in iPlant's Discovery Environment Phylogenetic Independent Contrasts (PIC) is a subset of phylogenetic comparative methods, which use information on the evolutionary relationships of organisms (phylogenetic trees) to test for correlated evolutionary changes in two or more traits. PIC is a statistically-based approach that uses the phylogenetic tree and evolutionary branch lengths as a guide to determine whether two or more quantitative characters are evolutionarily correlated. PIC can help users discern between characters that are similar because of a common evolutionary history from those which are similar for other reasons, such as an adaptive response to environmental conditions.

BLOSSOMS - Classifying Animals by Appearance Versus DNA Sequence Visit the MIT BLOSSOMS website at blossoms.mit.edu Video Summary: The topic of this video module is how to classify animals based on how closely related they are. The main learning objective is that students will learn how to make phylogenetic trees based on both physical characteristics and on DNA sequence. Students will also learn why the objective and quantitative nature of DNA sequencing is preferable when it come to classifying animals based on how closely related they are. Knowledge prerequisites to this lesson include that students have some understanding of what DNA is and that they have a familiarity with the base-pairing rules and with writing a DNA sequence. However, these topics are covered briefly in the lesson. All necessary hand-outs and worksheets are downloadable in Word and PDF formats, and materials needed for the lesson are only paper and pen/pencil. The types of in-class activities for this lesson include creating phylogenetic trees, calculating pair-wise differences of the gene sequences of 10 animals, and group discussions. This learning video also includes a lesson extension for teachers and students with access to a computer and the Internet. (See Teacher Guide segment) This extension introduces teachers to free online software that will allow students to use the program written by scientists to examine the hundreds and thousands of letters of the DNA sequences of mammals, count the pair-wise differences and make phylogenetic trees.

Sir Peter Crane, Darwin and modern science, Thurs 9 July chicago, The importance of trees: recent progress with understanding the history of plant life Professor Sir Peter Crane (University of Chicago, Illinois, USA) Summary: Much was learnt about plant evolution in the first 100 years following On the Origin of Species, but progress in recent decades has been equally rapid, especially with new approaches to develop and test different kinds of evolutionary trees that model the specific pathways of plant evolution. Such trees provide a basis for understanding how the major groups of living and fossil plants are interrelated, and in turn, this has opened up possibilities for research in many new areas. In this lecture, I will review our current understanding of the origin and early diversification of land plants, vascular plants, seed plants and flowering plants. In all four cases, many questions remain to be answered, but improved insights have come, most reliably, by integrating information from living and fossil plants towards the development of increasingly robust phylogenetic and stratigraphic patterns. Among living plants, the widespread application of phylogenetic techniques based on molecular sequence data, together with new studies of plant structure, function and development, have been especially influential. Among fossil plants, new perspectives continue to come from studies of recently discovered and classic localities, as well as from information obtained through the application of new techniques.

Why Study the Tree of Life? The Tree of Life is of great scientific interest, but does it have immediate practical value? The answer is a definite Yes! By providing a chronicle of past evolutionary events, phylogenetic trees have become central to understanding the process of evolution, and therefore to the interpretation of all biological information. Phylogenetic comparisons with model organisms (such as the chimpanzee, mouse, zebra fish, and yeast) are providing major insights into the structure and function of the human genome, knowledge that will enable us to address a wide variety of human disorders. Medical journals routinely publish phylogenetic trees, which have proven to be critical in identifying and tracing the origins of emerging infectious diseases such as HIV, the Ebola and West Nile viruses, anthrax, and influenza. Travels in the Great Tree of Life was produced for the Yale Peabody Museum of Natural History with the support from the US National Science Foundation through the CIPRes and Angiosperm Tree of Life Programs.

Evolution Within the Human Forebrain.wmv The Evolution of the Human Forebrain based upon the Parameters of Input Specificity and Phylogenetic Age. The cortical and thalamic parcellations of Brodmann, von Economo and Hassler are each quantitatively correlated to a specific Cartesian coordinate value designating discrete levels for both age and input basic parameters. The variable of phylogenetic age is represented in the cortex by the five circumferential growth rings demonstrated by Sanides, plus an additional growth ring detected intermediate to the fifth and sixth age levels and designated as "prekoniocortex." The paleocortex and the archaecortex are the two primordial neocortical precursors that form the mammalian neocortex. In contrast to the arrangement in the planar cortex, six phylogenetically distinct "growth shells" are detected in the three-dimensional thalamus and are designated after the corresponding schematic levels of Rolf Hassler's paradigm of hexapartition of unit-thalamic inputs. The subthalamus and the epithalamus ***ogously represent the primordial diencephalic precursors of the mammalian dorsal thalamus, Both the neocortex and the dorsal thalamus evolved in response to the necessity for a more comprehensive blending of inputs from differing neuraxial levels. Unlike the age variable, the parameter of input specificity is most readily apparent in the dorsal thalamus; which is the site of termination for each major forebrain input. Accordingly, the four*** individual units of the parameter of ...

The Lie of Evolution - i succeed where Kirk Cameron Failed When i saw Kirk Cameron's Crocoduck it immediately smashed my outlook on evolution because such a creature is impossible within evolutiionary theory. However, it turned out to be a fabricated drawing in order to highlight missing evidence for evolution. The Crocoduck maybe a figment of brother Kirk's mind but i can demonstrate some genuine evidence that smashes the phylogenetic tree to smithereens.

Phylograms - evolutionary trees made using proteins Response to C0nc0rdance. Thankyou C0nc0rdance, I had fun making phylogenetic trees using protein sequences. Pause for influenza, I made an interesting discovery. Different protein sequences showed a different evolutionary origin for viruses (including swine flu and bird flu). These results were very puzzling. This is because viruses can swap their genes when two infect the same cell of an animal, such as a pig in the case of swine flu. This complicates matters for studying the evolution of viruses, maybe it makes more sense to study the evolution of individual proteins? anyway peace :) European Molecular Biology Laboratory (EMBL) ClustalW2 National Center for Biotechnology Information (NCBI) m.nih.gov

Evolution vs. Intelligent Design: Does Homology = Relatedness? Paternity tests use inherited DNA markers as a way to determine relatedness. So does phylogenetics. If you want to learn to make your own phylograms: Here's some resources for more info on phylograms. The Wikipedia article on phylogenetic trees Science and Sensibility does a phylogenetic tree of science blogs science_ The Tree of Life web project, based on 16S rDNA sequences Here's a poster you can order if you love phylogenetics as much as I do. A dendrogram is a broad term for the diagrammatic representation of a phylogenetic tree. A cladogram is a tree formed using cladistic methods. This type of tree only represents a branching pattern, ie, its branch lengths do not represent time. A phylogram is a phylogenetic tree that explicitly represents number of character changes through its branch lengths. An ultrametric tree or chronogram is a phylogenetic tree that explicitly represents evolutionary time through its branch lengths.
