Three generations, one body

⭐ The strongest thing in this room, and it is ordinary embryology.

A human female does not make her eggs in adulthood. Her oogonia proliferate before she is born — reaching a peak of roughly seven million around the fifth month of gestation — and then enter meiosis and arrest, mid-division, in prophase I. Most are lost; about one to two million remain at birth, a few hundred thousand by puberty, and each one finishes the division it started only in the month it is ovulated, decades later.

Which means: the egg you came from was already present in your mother's ovaries while your mother was a fetus inside your grandmother. Three generations physically nested in one body, simultaneously, for a few months in the 1900s or whenever your family's dates fall. The worm-tree is not a metaphor for this. Nesting is what it literally looks like. Note the pause, too: your first cell division began before your mother was born and finished shortly before you did. One cell, holding its breath, for a generation.
