TL;DR: Traditional theoretical models for the evolution of paternal care can be reexamined, focusing on male-female interactions as a possible key to understanding parental strategies, and a multidisciplinary approach that also considers epigenetic and transgenerational effects promises to open new avenues to explain the flexible nature of paternal Care in primates.
