Overview

New two-step method efficiently combines gene trees for accurate species tree inference, hinting at further optimization needs.

Key Points

  • Our method shows promise for species tree inference while addressing gene tree estimation uncertainties.
  • Joint estimation (using BPP) shows superior performance compared to two-step methods under high incomplete lineage sorting.
  • Two-step approaches like RevBayes-MSC achieve better accuracy with known gene trees, highlighting their advantages.
  • Empirical analysis on gibbon data indicates conflicting phylogenetic signals, demonstrating the challenges in tree inference.
