59. Researchers are reconstructing a phylogeny for five vertebrate taxa. Two distantly related desert species exhibit nearly identical limb morphology adapted for burrowing, yet multilocus genomic analyses reveal thousands of shared derived nucleotide substitutions between one of these desert species and a forest-dwelling taxon. Which line of evidence provides the strongest support for inferring true common ancestry among these taxa?
(A) Overlapping geographic distributions
(B) Occupation of comparable ecological niches
(C) Similar limb morphology associated with burrowing behavior
(D) Convergent morphological traits shaped by environmental pressure
(E) Shared derived DNA sequence substitutions across multiple independent loci
