Q

What evidence supports this theory?

A
  • African mothers spend much time stretching and dangling their babies, this lead to more muscle strength in babies and early walking ages
  • It is also necessary because African babies spend much time bundled up in clothes and strapped onto the mothers
  • Variability in timing of milestones due to experience
