But who taught them? All modern pack animals teach their young how to hunt
in a pack. The main point is that why would you take a juvinile animal, who
will no doubt screw up the hunt and risk loosing a meal and possibly starve.

The juviniles needed to be taught by the most experiance hunters in the pack
and I don't think sub adults fit this bill. Look at modern pack animals if
you have any questions. The young are not allowed to participate in the hunt
until the adults are sure they won't screw it up. So why would they leave
such an important job to the sub adults.
