Newborn babies' brains aren't "underdeveloped" compared with those of other primates at birth, a new study suggests.
In the past, scientists typically compared brain development between species by measuring how much each species' newborn brain size differs from its adult brain size. Compared with other primates, human babies' brains are significantly smaller than adults' brains. Meanwhile, newborn and adult primates have a smaller gap, which has led to the popular misconception that human newborns are "underdeveloped" in comparison.
