A new study overturns decades of assumptions about microbial evolution by proving that more genomic data can distort—not clarify—life's earliest branches. The corrected tree reveals how statistical rigor, not data volume, holds the key to understanding primordial life.

Standard methods misplace 33% of deep microbial branches when analyzing >1,000 genomes

The new algorithm reduces errors by 52% using statistical checks against "long-branch attraction" artifacts

Next step: Applying this to controversial Archaea-Eukarya divergence timing

Microbiologists can now trust evolutionary models for synthetic biology applications

The study analyzed 11.4 billion DNA base pairs across 3,072 genomes—the largest test of microbial phylogenetics to date.
