  • Employing methods for calculating evolutionary rates.
  • Constructing molecular evolutionary trees by estimating nucleotide substitutions and amino acid changes.

Main Results:

  • The study outlines a framework for quantitative analysis of viral evolution.
  • Methods are demonstrated for estimating evolutionary rates and divergence times.
  • Application to HBV and HCV provides insights into their specific evolutionary patterns.

Conclusions:

  • The described methods provide a robust approach for analyzing hepatitis virus evolution.
  • Quantitative analysis of genetic sequences aids in understanding viral adaptation and diversification.
