(Top) MHD of dp4 plotted against cranial length. The dashed line illustrates the negative slope for the significant correlation of dp4 in strepsirrhines. (Bottom) MHD of M1 plotted against cranial length. The dashed line illustrates the negative slope for the significant correlation of M1 in strepsirrhines; the solid line illustrates the positive slope for the significant correlation of M1 in Old and New World monkeys. Hg, Hapalemur griseus; Ll, Lepilemur leucopus; Pc, Propithecus coquereli
