Brain growth in babies is linked to the amount of time and energy mothers "invest," according to new research. The study of 128 mammal species, including humans, shows that brain growth in babies is determined by the duration of pregnancy and how long they suckle. The research concludes that the longer the pregnancy and breastfeeding period in mammals, the bigger the baby's brain grows.
