Body odours as putative chemosignals in the father-child relationship: New insights on paternal olfactory kin recognition and preference from infancy to adolescence Physiol. Behav. (IF 2.9) Pub Date : 2024-03-01 Laura Schäfer, Agnieszka Sorokowska, Kerstin Weidner, Jürgen Sauter, Alexander H. Schmidt, Ilona Croy
Children's body odours are effective chemical cues in the parent-child relationship. Mothers can recognize the odour of their child and prefer this odour over that of unfamiliar children. This effect is mediated by genetic similarity and developmental stage and is therefore suited to promote parental care at pre-pubertal stage, while facilitating incest avoidance at (post-)pubertal stage. The present
