work for his livingbut only when he can do his genes more good by
leaving his mother free to rear his little brothers and sistersthan by
staying behind himself. The older a child isthe less relative benefit
does he derive from each pint of milk. This is because he is bigger
and a pint of milk is therefore a smaller proportion of his require-
mentand also he is becoming more capable offending for himself if
he is forced to. Therefore when an old child drinks a pint that could
have been invested in a younger childhe is taking relatively more
parental investment for himself than when a young child drinks a
pint. As a child grows olderthere will come a moment when it would
pay his mother to stop feeding himand invest in a new child instead.
Somewhat later there will come a time when the old child too would
benefit his genes most by weaning himself. This is the moment when
a pint of milk can do more good to the copies of his genes that may be
present in his brothers and sisters than it can to the genes that are
present in himself.
