Have you ever wondered why men have nipples if they never breastfeed?
The answer lies deep in human embryonic development. During the first weeks in the womb, male and female embryos follow the same biological blueprint. Nipples form before gender is even determined. Only later does the Y chromosome activate, triggering male development — but by then, the nipples are already there.
This fascinating evolutionary byproduct reveals how closely connected we all are at the earliest stages of life.
