Clock model makes a large difference to age estimates of long-stemmed clades with no internal calibration: a test using Australian grasstrees
BACKGROUND: Estimating divergence times in phylogenies using a molecular clock depends on accurate modeling of nucleotide substitution rates in DNA sequences. Rate heterogeneity among lineages is likely to affect estimates, especially in lineages with long stems and short crowns (“broom” clades) and...
