Final answer:
Primitive reflexes in newborns have adaptive value as they help the baby survive and meet their basic needs. The sucking reflex allows newborns to extract milk from the mother's nipple or a bottle, while the grasp reflex helps them hold onto objects and maintain physical contact with their caregiver.
Step-by-step explanation:
The adaptive value of primitive reflexes in newborns is that they help the baby survive and meet their basic needs. For example, the sucking reflex allows newborns to extract milk from the mother's nipple or a bottle, increasing their chances of feeding and surviving. The grasp reflex helps babies hold onto objects placed in their hands, which can be important for maintaining physical contact with their caregiver and satisfying their need for touch and support.
