A small point not to be overlooked: it's a heckuva lot easier to drive a
pack of hyenas away from their kill if you're a lion in a pack of your own
than it is if your alone.
In fact, ignore hunting for a second - or accept at face value the fact
that there is no energy benefit to pack-hunting. Just look at pirating
kills from other animals.
A lone lion can only take prey from a cheetah (or three) or a leopard if it
hasn't yet treed its booty.
A pack of lions could do the same, and drive off a pack of dogs, hyenas, or
any lesser sized hunter.
The cost of taking kills from others is significantly less than the cost of
hunting for yourself. But you can't take on a pack of enemies alone.
I think this might only apply to lions, however - and perhaps savannah
Africa has undergone an evolutionary social arms race. Lions are pretty
much the only cats that hang in packs, after all. Would it apply to
wolves? Not presently, but perhaps canid ancestors faced just this same
arms race in the past, and now live with that legacy.
Then again, maybe I just need a nap....
