There’s a theory about the specific suckling technique the breast engenders, which develops the muscles needed for speech. Williams becomes convinced – and has convinced me – that breasts evolved as a driver of female and infant survival, and men’s obsession with them arrived not “in lockstep”, but some time later. “Perhaps, all along, the breasts were calling the shots,” she concludes.
The composition of the breast makes …[breastmilk]… a magnet for environmental toxins, so they “carry the burden of the mistakes we have made in our stewardship of the planet”.
This is from a book review on guardian. Interesting but not something that will be in my read stack anytime soon.
