Lesson 20-1     Snake poison

How it came aboutthat snakes manufactured poison is a mystery. Over the periods their saliva, amild, digestive juice like our own, was converted into a poison that defiesanalysis even today. It was not forced upon them by the survival competition;they could have caught and lived on prey without using poison, just as thethousands of non- poisonous snakes still do. Poison to a snake is merely aluxury; it enables it to get its food with very little effort, no more effortthan one bite. And why only snakes? Cats, for instance, would be greatlyhelped; no running fights with large, fierce rats or tussles with grown rabbits-- just a bite and no more effort needed.
