Final answer:
Human infants and children differ from young nonhuman primates such as chimpanzees or bonobos in social behavior, cognitive development, and physical development.
Step-by-step explanation:
Human infants and children differ from young nonhuman primates such as chimpanzees or bonobos in several ways. One significant difference is in their social behavior. Human infants and children are highly dependent on their caregivers for a longer period of time compared to nonhuman primates. They also have a greater capacity for language and complex communication. In terms of cognitive development, human infants and children show a much faster rate of learning and problem-solving abilities compared to young nonhuman primates. They have a larger brain size and are capable of more advanced cognitive processes. Additionally, there are differences in physical development. Human infants have a longer period of dependency and slower maturation compared to nonhuman primates. They also have a unique upright bipedal posture that allows them to walk on two feet.
