South Africans have taken to Twitter to share an unusual practice referred to as the "African DNA test".
A father was photographed taking two babies to a farm and leaving them on the floor, surrounded by cows.South African Twitter users immediately understood what the picture meant and said it's a form of DNA test.
They revealed that if the child belongs to the man, the cows will not attack the baby, but if the child is not the man's biological child, the cows will attack. See some comments below.
