Bearing or producing live fetuses; relating to viviparous reproduction (giving birth to live young).
From Latin 'foetus' (fetus) + '-parous' (from 'parere,' meaning 'to give birth'). This biological term distinguishes organisms that develop fetuses internally from those that lay eggs.
This word highlights a major evolutionary divide: mammals like humans are foetiparous, meaning we invest heavily in developing each baby internally, which is much riskier but allows for smarter, more dependent babies.
