 from place to place by taking a branch that was 

 on fire and starting another piece burning before 

 the old one was entirely destroyed. After a while, 

 they learned that it was just as easy to carry fire 

 smouldering in a bit of punk as it was to carry a 

 flaming branch. Still, they did not know how to 

 preserve it except by constantly carrying it around, 

 and tribes must have been wiped out from time 

 to time by the loss of their fire. Then somebody 

 overed that it was possible to make fire by 

 rubbing one piece of wood against another until 

 sufficient heat was secured to burst into flame. 

 So they answered the question of how fire could 

 be produced and that took them a long step for*
