Area of Science:

  • Evolutionary Biology
  • Digital Humanities
  • Computational Linguistics

Background:

  • Phylogenetic methods are increasingly applied beyond evolutionary biology to fields like linguistics and textual criticism.
  • Despite widespread adoption, critical evaluations of these methods' suitability for non-biological data are limited.

Purpose of the Study:

  • To critically assess the effectiveness of phylogenetic methods in reconstructing the evolutionary history of manuscript texts.
  • To validate these methods using artificial manuscripts with a known, true phylogeny.

Main Methods:

  • Application of phylogenetic methods to a dataset of artificial manuscripts created by modern scribes.
  • Analysis of manuscript evolution, considering factors like ancestral form survival and multiple descendant lineages.

Related Experiment Videos

  • Statistical analysis of rate variation in textual change.

    • Main Results:

    • Phylogenetic methods successfully reconstructed a significant portion of the known true phylogeny for artificial manuscripts.
    • The study confirmed the applicability of these methods despite differences between manuscript and biological evolution (e.g., higher rates of common descent).
    • Variation in rates of textual change across different locations was found to follow a gamma distribution, similar to DNA sequence evolution.

    Conclusions:

    • Phylogenetic methods are a valuable tool for reconstructing manuscript evolution and understanding textual relationships.
    • The findings support the growing use of phylogenetic approaches in textual criticism and the creation of critical editions.
    • The observed rate variation pattern suggests underlying similarities in evolutionary processes across diverse data types.
