nuzzling superiors
What does "nuzzling superiors" mean? Does it mean humbling in front of more powerful animals?
We do not know when feelings such as love and grief became more complex than the simple intuitions of animals compelled by an overriding drive to survive and breed, opportunistically fondling their mates, nurturing their young or nuzzling their superiors, briefly grieving when they go.or it may mean showing respect to the elderly?
