WebThe FEL method found evidence of pervasive positive diversifying selection in all 12 PCGs except for nad3, which only had 30 sites under negative selection (at p ≤ 0.05; Supplementary Table S4). Intriguingly, nad1 was special again, with only one site under pervasive positive diversifying selection and 137 sites under negative selection ...
