文摘
- •
Phylogenetics combining NGS and Sanger sequences elucidate an ancient divergence.
- •
Sub-sampling suggests supermatrix more accurate than partially parametric coalescent analyses.
- •
The root of Ischyropsalidoidea is characterized by high levels of gene tree conflict.
- •
Concordance factors reject ILS as the sole contributor to gene tree conflict.
- •
Increased taxon sampling is important for estimating ancient radiations.
