Predator Call

Hunting has been a part of human activities for a long period of time.  Even before there were Homo sapiens, there were hunters.  The reason for the shift from primary gathering to a varied diet consisting of meat is still a topic of debate.  One theory is that environmental factors changed the landscape and necessitated the development of hunting.  Another theory is that our growing brains needed added nutrients to sustain, which correlated with our increased intelligence and the ability to hunt.  No matter what the real root, it is accepted that hunting has been an integral part of our species. 
 
Even with the advent of animal domestication and agriculture, hunting still remained a contributing factor to the human food supply.  The materials gathered from hunting animals (fur, leather, sinew, bone, protein) were valuable commodities, even among early farmers.  The hunting tools man used at the first hunts were rock and crude spears.  They soon learned various techniques that made hunting an easier task, such as using animal calls to lure animals.  Outsmarting animals has been an essential part of human development.
