Margaret Mead's famous line reframes fatherhood as a cultural choice rather than a biological mandate. The evolutionary baseline from hunter-gatherer societies shows men holding babies only 3–22% of the time—even in the most father-involved foraging groups, mothers still do the bulk of childcare. Modern involved fatherhood is therefore an upgrade built on top of a sparse evolutionary foundation.
