Newborn human brains are relatively small due to evolutionary adaptations that prioritize safe childbirth and maternal health. The human pelvis has evolved to accommodate bipedal locomotion, making it narrower, which limits the size of the baby's head at birth. Additionally, a smaller brain at birth allows for rapid postnatal growth and development, enabling the brain to adapt to environmental influences and experiences during early life. This balance of size and adaptability is crucial for survival and development.
They have a brain the size that is proportional to their small bodies.

Babies have small stomachs and they metabolize their food quickly, so they need to be fed small amounts often.
Some examples of big animals with relatively small brains are elephants, blue whales, and sperm whales. These animals have massive bodies, but their brain size in proportion to their body size is smaller compared to other animals.
