Comment on 'Phylogenomics resolves the timing and pattern of insect evolution'

摘要

Misof et al. (Reports, 7 November 2014, p. 763) used a genome-scale data set to estimate the relationships among insect orders and the time scale of their evolution. Here, we reanalyze their data and show that their method has led to systematic underestimation of the evolutionary time scale. We find that key insect groups evolved up to 100 million years earlier than inferred in their study.
