To evaluate whether protein and nucleotide divergence patterns align with non-Darwinian neutral evolution rather than natural selection.
Modeled expected rates and distributions of amino acid changes under neutral evolutionary assumptions.
Compared theoretical model expectations against observed rates of protein and DNA sequence variations across taxa.
Demonstrated that observed amino acid and nucleotide substitution rates correspond closely to expectations from neutral drift models.
Identified that a significant proportion of molecular divergence accumulates without direct adaptive selective advantages.

Implication

Theoretical study uncovers neutral substitution dynamics across protein and DNA sequences, indicating that random genetic drift drives molecular evolutionary changes.
