Species Tree Likelihood Computation Given SNP Data Using Ancestral Configurations
Species Tree Likelihood Computation Given SNP Data Using Ancestral Configurations DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Hang Fan, M.S. Graduate Program in Statistics The Ohio State University 2013 Dissertation Committee: Professor Laura Kubatko, Advisor Professor Bryan Carstens Professor Radu Herbei 1 Copyright by Hang Fan 2013 2 Abstract Inferring species trees given genetic data has been a challenge in the field of phylogenetics because of the high intensity during computation. In the coalescent framework, this dissertation proposes an innovative method of estimating the likelihood of a species tree directly from Single Nucleotide Polymorphism (SNP) data with a certain nucleotide substitution model. This method uses the idea of Ancestral Configurations (Wu, 2011) to avoid the computation burden brought by the enumeration of coalescent histories. Importance sampling is used to in Monte Carlo integration to approximate the expectations in the computation, where the accuracy of the approximation is tested in different tree models. The SNP data is processed beforehand which vastly boosts the efficiency of the method. Gene tree sampling given the species tree under the coalescent model is employed to make the computation feasible for large trees. Further, the branch lengths on the species tree are optimized according to the computed species tree likelihood, which provides the likelihood of the species tree topology given the SNP data. For inference, this likelihood computation method is implemented in the stepwise addition algorithm to infer the maximum likelihood species tree in the tree space given the SNP data, and simulations are conduced to test the performance. -

Language and Geometry a Method for Comparing the Genealogical and Structural Relatedness Between Pairs of European Languages
4 Journal for EuroLinguistiX 11 (2014): 4-13 Jacques François Language and Geometry A Method for Comparing the Genealogical and Structural Relatedness between Pairs of European Languages Abstract In the second half of 19th century, two German linguists, August Schleicher and Johannes Schmidt, worked out a method of genealogical comparison of the Indo-European languages which crucially rested on inflectional morphology and phonology (so-called Stammbaum hypothesis by Schleicher) supplemented by wave-like spreading (so-called wave-hypothesis by Schmidt) of such properties amongst geographically neighbouring languages. First, this method is applied to four European languages: Dutch, English, French and German. Next, a list of 18 structural properties of the four languages is collected in order to assess the structural relatedness of each pair of languages. The two resulting charts turn out to be similar concerning the proximity between Dutch vs. German, but quite disparate concerning the latter vs. English and French. The structural chart is insightful, but weighting the collected structural properties (on the basis of criteria to be justified) might generate a differently shaped chart. Sommaire Dans la seconde moitié du 19e siècle, deux linguistes allemands, August Schleicher et Johannes Schmidt, ont élaboré une méthode de comparaison généalogique des langues indo-européennes essentiellement basée sur la morphologie flexionnelle et la phonologie (hypothèse du Stammbaum de Schleicher) complétée par une dissémination ‘ondulatoire’ (hypothèse de Schmidt) de propriétés de ce type entre des langues géographiquement voisines. En premier lieu, cette méthode est appliquée à quatre langues européennes : allemand, anglais, français et néerlandais. Ensuite, une liste de 18 propriétés structurales des quatre langues est établie afin de mesurer la proximité structurale entre celles-ci. -
Outer and Inner Indo-Aryan, and Northern India As an Ancient Linguistic Area
Acta Orientalia 2016: 77, 71–132. Copyright © 2016 Printed in India – all rights reserved ACTA ORIENTALIA ISSN 0001-6483 Outer and Inner Indo-Aryan, and northern India as an ancient linguistic area Claus Peter Zoller University of Oslo Abstract The article presents a new approach to the old controversy concerning the veracity of a distinction between Outer and Inner Languages in Indo-Aryan. A number of arguments and data are presented which substantiate the reality of this distinction. This new approach combines this issue with a new interpretation of the history of Indo- Iranian and with the linguistic prehistory of northern India. Data are presented to show that prehistorical northern India was dominated by Munda/Austro-Asiatic languages. Keywords: Indo-Aryan, Indo-Iranian, Nuristani, Munda/Austro- Asiatic history and prehistory. Introduction This article gives a summary of the most important arguments contained in my forthcoming book on Outer and Inner languages before and after the arrival of Indo-Aryan in South Asia. The 72 Claus Peter Zoller traditional version of the hypothesis of Outer and Inner Indo-Aryan purports the idea that the Indo-Aryan Language immigration1 was not a singular event. Yet, even though it is known that the actual historical movements and processes in connection with this immigration were remarkably complex, the concerns of the hypothesis are not to reconstruct the details of these events but merely to show that the original non-singular immigrations have left revealing linguistic traces in the modern Indo-Aryan languages. Actually, this task is challenging enough, as the long-lasting controversy shows.2 Previous and present proponents of the hypothesis have tried to fix the difference between Outer and Inner Languages in terms of language geography (one graphical attempt as an example is shown below p. -
Georg Von Der Gabelentz the Published Version of This Article Is In
Georg von der Gabelentz The published version of this article is in the Oxford Research Encyclopedia of Linguistics: http://linguistics.oxfordre.com/abstract/10.1093/acrefore/9780199384655.001.0001/acrefore- 9780199384655-e-379 James McElvenny [email protected] Summary The German sinologist and general linguist Georg von der Gabelentz (1840–1893) occupies an interesting place at the intersection of several streams of linguistic scholarship at the end of the nineteenth century. As Professor of East-Asian languages at the University of Leipzig from 1878 to 1889 and then Professor for Sinology and General Linguistics at the University of Berlin from 1889 until his death, Gabelentz was present at some of the main centers of linguistics at the time. He was, however, generally critical of mainstream historical-comparative linguistics as propagated by the neogrammarians and instead emphasized approaches to language inspired by a line of researchers including Wilhelm von Humboldt (1767–1835), H. Steinthal (1823–1899), and his own father, Hans Conon von der Gabelentz (1807–1874). Today Gabelentz is chiefly remembered for several theoretical and methodological innovations which continue to play a role in linguistics. Most significant among these are his contributions to cross-linguistic syntactic comparison and typology, grammar-writing, and grammaticalization. His earliest linguistic work emphasized the importance of syntax as a core part of grammar and sought to establish a framework for the cross-linguistic description of word order, as had already been attempted for morphology by other scholars. The importance he attached to syntax was motivated by his engagement with Classical Chinese, a language almost devoid of morphology and highly reliant on syntax. -
The Shape of Phylogenetic Trees (Review Paper)
REVIEW PAPER: THE SHAPE OF PHYLOGENETIC TREESPACE KATHERINE ST. JOHN Abstract: Trees are a canonical structure for representing evolutionary histories. Many popular criteria used to infer optimal trees are computationally hard, and the number of possible tree shapes grows super-exponentially in the number of taxa. The underlying structure of the spaces of trees yields rich insights that can improve the search for optimal trees, both in accuracy and running time, and the analysis and visualization of results. We review the past work on analyzing and comparing trees by their shape as well as recent work that incorporates trees with weighted branch lengths. Keywords: tree metrics, treespace, maximum parsimony, maximum likelihood. Tree structures have long been used to represent the evolutionary histories of sets of species. For example, the tips of the trees represent extant species and the internal nodes represent speciation events. Despite its simplicity, the tree model captures much of the complexity of the underlying phenomena. However, the sheer number of possibilities forces many simply presented operations on trees to be computationally hard. For example, the maximum parsimony criteria (Farris, 1970; Fitch, 1971) that seeks the tree with the minimal number of changes across the edges is compu- tationally hard to compute exactly (Foulds and Graham, 1982). The addition of weights on the branches, to denote quantities such as amount of evolutionary change, the time, or the confidence on the existence of the branch, adds complexity to the model (Felsenstein, 1973, 1978). A pop- ular corresponding optimality criteria for weighted trees, the maximum likelihood criteria, is also computationally hard (Roch, 2006). -

Verifying the Consistency of the Digitized Indo-European Sound Law System Generating the Data of the 120 Most Archaic Languages from Proto-Indo-European
Verifying the Consistency of the Digitized Indo-European Sound Law System Generating the Data of the 120 Most Archaic Languages from Proto-Indo-European Jouna Pyysalo, Aleksi Sahala, and Mans Hulden ABSTRACT: Using state-of-the-art finite-state technology (FST) we automatically generate data of the some 120 most archaic Indo-European (IE) languages from reconstructed Proto-Indo-European (PIE) by means of digitized sound laws. The accuracy rate of the automatic generation of the data exceeds 99%, which also applies in the generation of new data that were not observed when the rules representing the sound laws were originally compiled. After testing and verifying the consistency of the sound law system with regard to the IE data and the PIE reconstruction, we report the following results: a) The consistency of the digitized sound law system generating the data of the 120 most archaic Indo-European languages from Proto-Indo-European is verifiable. b) The primary objective of Indo-European linguistics, a reconstruction theory of PIE in essence equivalent to the IE data (except for a limited set of open research problems), has been provably achieved. The results are fully explicit, repeatable, and verifiable. 1. On the digitalization of Indo-European sound laws with finite-state technology (FST) 1.1 Sir William JONES’ (1788) groundbreaking announcement of a genetic relationship between European languages including Greek and Latin, Sanskrit, and other language groups and the existence of a common ancestor of these Indo- European (IE) languages marks the birth of modern comparative linguistics. Soon after, the pioneers Rasmus RASK, Franz BOPP, and others confirmed the existence of systematic correspondences between the ‘letters’ (phonemes) of the IE languages, thus verifying Sir William’s initial assessment: the Indo-European languages are indeed genetically related and descended from a common source, now known as Proto-Indo-European (PIE). -
The Past in the Present
The Past in the Present THOMAS R. TRAUTMANN University of Michigan [email protected] Abstract: The theory-deadness of antiquity under the ideology of modernism, the theory-deadness of Asia under Eurocentrism, and the theory-deadness of the precolonial under post-colonial theory converge to hide the aliveness of ancient Indian phonological analysis in the present. This case study of the hiddenness of the past in the present leads to a consideration of how historians of the ancient world may act to illuminate the present. Faulkner has said, “The past is not dead, it is not even past.” The objective of this paper is to show, rigorously and through a par- ticular case, that the ancient past is essential to the understanding of the present, because the past lives in the present. If the argument succeeds it follows that the study of ancient history is not something that comes to an end at some date in the past, but has a continuing life in the present. It also follows that historians of the recent past cannot elucidate their field fully without the help of historians of the ancient past. It is not easy to demonstrate, because contemporary forces actively hide the continuing life of the past in the present. The hiddenness of this history is produced. There are, to be sure, areas of contemporary life whose pastness is not obscure. Everyday life contains abundant material contrivances and prac- tical routines that we know we owe to the ancestors. Learning from our parents how to button a button or tie a shoe, we set out upon a lifetime of performed routines that reenact techniques and use products of human inventiveness that we vaguely know we owe to some anonymous fore- bear, transmitted to us by an unbroken chain of teaching and performed iterations. -
The Indo-Europeanization of the World from a Central Asian Homeland: New Approaches, Paradigms and Insights from Our Research Publications on Ancient India
Journal of Social Science Studies ISSN 2329-9150 2016, Vol. 3, No. 1 The Indo-Europeanization of the World from a Central Asian Homeland: New Approaches, Paradigms and Insights from Our Research Publications on Ancient India Sujay Rao Mandavilli (Corresponding author) Independent Scholar, India E-mail: [email protected] Received: August 3, 2015 Accepted: September 8, 2015 Published: September 10, 2015 doi:10.5296/jsss.v3i1.8278 URL: http://dx.doi.org/10.5296/jsss.v3i1.8278 Abstract In this paper, we bring together the concepts put forth in our previous papers and throw new light on how the Indo-Europeanization of the world may have happened from the conventional Central Asian homeland and explain the same using maps and diagrams. We also propose the ‘Ten modes of linguistic transformations associated with Human migrations.’ With this, the significance of the proposed term ‘Base Indo-European’ in lieu of the old term ‘Proto Indo-European’ will become abundantly clear to most readers. The approaches presented in this paper are somewhat superior to existing approaches, and as such are expected to replace them in the longer run. Detailed maps and notes demonstrating and explaining how linguistic transformations might have taken place in South Asia are available in this paper as understood from our previous research papers, and scholars from other parts of the world are invited to develop similar paradigms with regard to their home countries as far as the available data or evidence will allow them. This will help piece together a gigantic jig-saw puzzle, and lead to a revolution of sorts in the field, leading to a ripple-effect that will strongly impact several other related fields of study as well.
