Question

Watch the first part of a video about what knowledge babies are born with (0.00-1.44). How are the words below connected to babies’ instincts and abilities —and how are some of these instincts related to other animals?

Answer

  1. If you submerge a baby under water, it’ll intuitively hold its breath. Other mammals, birds and reptiles share the same instinct.
  2. A touch on the cheek makes a baby turn its head and suck.
  3. A touch on the palm of the hand makes a baby grasp your finger – perhaps the trace of an ancestral instinct inherited from monkeys, where the young grasp their mothers’ backs.
  4. A startle causes the baby to throw out its arms and legs – as if to grasp onto a tree branch while falling, like monkeys do.
  5. Babies are pre-programmed to walk. One hour after birth, if a baby’s feet touch the ground, they’ll start to take steps.
