A skua steals milk from an elephant seal's teat |
It certainly feels like it, at times. Like at 4am when papa is snoring and you’ve got a biro wedged under each eye lid, willing baby darling to suck its last so you can sink back into oblivion. Or, several months down the line, when the little monkey gets a mischievous glint in his eye and goes in for an experimental chew. But we must distinguish psychological from biological altruism here.
