Here is the news I came across on Internet:
Scientists studying South Africa's Wonderwerk Cave have discovered the world's earliest use of fire, adding fuel to a national obsession with the "braai," the local equivalent of a barbecue.
The braai is considered a unifying force in this diverse country, with cooking on fire an activity common to South Africans of all races, languages and religions.
