When Humans First Began Communicating With Animals . . .

Gray wolf pups are born blind and deaf. They weigh approximately 0.5 kg and depend on the mother for warmth. At ten to fifteen days of age, the pups' blue eyes open, but they only have control over their front legs, thus crawling is their only mode of mobility. Five to ten days later, the young are able to stand, walk, and vocalize. Pups are cared for by all members of the pack. Until they are 45 days old the pups are fed regurgitated food by all pack members. They are fed meat provided by pack members after that age. During the 20th to 77th day, the pups leave the den for the first time and learn to play fight. Interactions at this time, as well as the dominance status of the mother, ultimately determines their position in the pack hierarchy. Wolf pups develop rapidly, they must be large and accomplished enough to hunt with the pack with the onset of winter. At approximately ten months old, the young begin to hunt with the pack.

"I wonder about that cave, the fire that flickered and faded on damp walls as someone in the clan played a flute. Were they a family? Neighbors? What were their dreams and inventions? Did they know the long line of human beings that would follow their impulses to survive, even flourish in moments of reverie?"
