"maternal instincts" are species specific, may be many in number
in a given species, or, completely lacking etc. Maternal
investment is
used to describe benefits confered upon offspring by mothers, and
includes developmental/energy cost of producing egg, gestation,
lactation, paying for college etc. So, thinking about the adaptations
that underlie these and the conditions which elicit them is preferable to me
than to simply say maternal instinct. But thats just my opinion.
