*HA, hemagglutinin; HPD, highest posterior density; MP, matrix protein; NP, nucleoprotein; NS, nonstructural protein PA, acidic polymerase; PB1, basic polymerase 1; PB2, basic polymerase 2; tMRCA, time to the most recent common ancestor. †tMRCA estimated by using Bayesian molecular clock analysis. It represents the potential existing timing of a common ancestral node.
