Babies as young as 18 months old can tell when adults need help and will
often do their best to assist.
Lifting things, opening doors, picking up objects.
These early signs of helpfulness is a sign of humsns' altruism.. This is
rare in the animals. Chimps also display such kind of helpfulness. This
suggests that the evolutionary roots of altruism go back to common
ancestors shared beteen humans and chimpanzees.
Tests also show that if an adult struggles to pick up a dropped
clothespin in front of an infant, it quickly crawls over picks up the
clothespin and hands it over to the adult. Chimpanzees performed a
similar task. But human babies were found to perform better at opening
up doors and stacking books in case the adult had his ands full.
