Fetal Olfactory Cognition Preadapts Neonatal Behavior in Mammals

Abstract

Several evolutionary adaptations have appeared in mammals that allow them to cope with the physical challenges presented during the early postnatal period. One set of general adaptations facilitates the maternal transmission of sensory information to the fetal and neonatal niches. The other set of adaptations results in fetuses and neonates developing the necessary sensory, cognitive, and motor abilities to be fully prepared to utilize maternally-provided information, even during the traumatic interval surrounding birth.
