Sporting activities are essentially modified forms of hunting behavior.
Viewing biologically, the modern footballer is revealed as a member of a disguised __1
hunting pack. His killing weapon has turned into a harmless football and his prey into a goal-mouth. If his aim is inaccurate and he scores a goal, __2
enjoys the hunter’s triumph of killing his prey. __3
To understand how this transformation has taken place we must briefly look up at our ancient ancestors. They spent over a million __4
year evolving as co-operative hunters. Their very survival depended on success __5
in the hunting-field. Under this pressure their whole way of life, even if their __6
bodies, became radically changed. They became chasers, runners, jumpers, aimers, throwers and prey-killers. They co-operate as skillful male-group __7
attackers.
Then, about ten thousand years ago, when this immensely long formative __8
period of hunting for food, they became farmers. Their improved intelligence,
so vital to their old hunting life, were put to a new use—that of penning, __9
controlling and domesticating their prey. The food was there on the farms,awaiting their needs. The risks and uncertainties of farming were no longer __10
essential for survival.
