Sequencing the genomes of all species would result in completely congruent phylogenies
the verdict
REFUTED
the evidence says no
confidence 14/100
Sequencing the genomes of all species would not produce completely congruent phylogenies because biological processes like incomplete lineage sorting, introgression, and rapid radiation naturally generate pervasive gene tree discordance.
