  1. a Averages of the divergence times estimated using the 2.3 Ga minimum constraint and the five ingroup root constraints (nodes A-K) and using the 1.198 ± 0.022 Ga constraint and the five ingroup root constraints (nodes L-P).
  2. b Credibility interval (minimum and maximum averages of the analyses under the five ingroup root constraints)
